OUCE 2015 – Hot Chicks

As you all know, we don’t spend a lot of time in marketing and I got a pro-tip to add hot chicks on the website. I don’t have any idea why but if it helps. JOIN OUCE 2015 NOW!

OUCE 2015: Bad Voltage Live

Every year at the OpenNMS Users Conference (OUCE) we have a good time. In fact, learning a lot about OpenNMS goes hand in hand with having fun.

At this year’s SCaLE conference, the team behind the Bad Voltage podcast was there to do a live version of the show. You can watch it on-line and see it went pretty well, and this gave me the idea to invite the gang over to Germany to do it again at the OUCE.

Since there may be one or two of my three readers who are unaware of Bad Voltage, I thought I’d post this little primer to bring you up to speed.

Bad Voltage is a biweekly podcast focused on open source software, technology in general and pretty much anything else that comes across the sometimes twisted minds of the hosts. They deliver it in a funny manner, sometimes NSFW, and for four guys with big personalities they do a good job of sharing the stage with each other. As I write this they have done 47 episodes, which is actually quite a nice run. For anyone who has done one or thought about doing a periodic podcast or column, know that after the first few it can be hard to keep going. It is a testament to how well these guys work together that the show has endured. Believe it or not, I actually put time into these posts and even I find it hard to produce a steady amount of content. I can’t imagine the work needed to coordinate four busy guys to create what is usually a good hour or three of podcast. (grin)

Bad Voltage as The Beatles

Anyway, I want to introduce you to the four Bad Voltage team members, and I thought it would be a useful analogy to compare them to the Beatles. As I doubt anyone who finds this blog is too young to not know of the Beatles, it should aid in getting to understand the players.

Bad Voltage - Jono Bacon Jono Bacon is Paul. If you have heard of anyone from Bad Voltage, chances are it is Jono. He’s kind of like the Elvis of open source. He was a presenter for LugRadio but is probably best known for his time at Canonical where he served as the community manager for Ubuntu. He literally wrote the book on open source communities. He is now building communities for the XPRIZE foundation as well as writing articles for opensource.com and Forbes and occasionally making loud music. He’s Paul because is he one of the most recognizable people on the team, and he secretly wishes I had compared him to John.

Bad Voltage - Bryan Lunduke Bryan Lunduke is John. He gets to be John because he has heartfelt opinions about everything, and usually good arguments (well, arguments at least) to back them up. He has passion, much of which he puts into promoting OpenSUSE. I’ve never met Bryan in person, but we’ve missed each other on numerous occasions. I missed him at SCaLE, he missed the Bad Voltage show I was on, and I missed him again at OSCON. And I’ll miss him in Fulda, as his wife is due to deliver their second child about that time, but he will be there virtually. He adds depth the the team.

Bad Voltage - Jeremy Garcia Jeremy Garcia is George. Although none of these guys could be described as “quiet”, he is the most reserved of the bunch, but when he opens his mouth he always has something interesting to say. You can’t be part of this group and be a wallflower. I’m not sure if he has a day job, but fifteen (!) years ago he founded Linuxquestions.org and has been a supporter of open source software even longer. He adds a nice, rational balance to the group.

 

Bad Voltage - Stuart Langridge Stuart is Ringo, known to his friends as “Aq” (short for “Aquarius” – long story). He is pretty unfiltered and will hold forth on topics as wide ranging as works of science fiction or why there should be no fruit in beer. He was also a member of LugRadio as well as an employee of Canonical, and now codes and runs his own consulting firm (when he is not selling his body on the streets of Birmingham). If there was a Bad Voltage buzzword bingo, you could count on him to be the first to say “bollocks”. He adds a random element to the group that can often take the discussion in interesting directions.

They have been working hard behind the scenes to plan out a great show for the OUCE. Since many of the attendees tend not to be from the US or the UK, it is hoped that the show will translate well for the whole audience, and to make sure that happens we will be serving beer (if you are into that sort of thing). If you were thinking about coming to the conference, perhaps this will push you over the top and make you register.

But remember, you don’t have to attend the OUCE to see the show. We do ask that you register and pony up 5€. Why? Because we know you slackers all too well and you might sign up and then decide to blow it off to binge on Regular Ordinary Swedish Meal Time. Space is limited, and we don’t want to turn people away and then have space left open. Plus, you’ll be able to get that back in beer, and the show itself promises to be priceless and something you don’t want to miss.

If that isn’t enough, there is a non-zero chance that at least one of the performers will do something obscenely biological (and perhaps even illegal in Germany), and you could say “I was there”.

Convince Your Boss to Send You to the OUCE

With this year’s OpenNMS Users Conference a little over a month away, I plan to be writing about it more in the run up to the event. I figured I should probably start on why you should go and, better yet, how to convince your boss to pay for the trip.

First off, if you aren’t using OpenNMS, why not? (grin)

In all seriousness, if you are happy with your network management solution you can stop reading now. But if you aren’t happy, are in the process of considering alternatives, or if you have a serious interest in discovering the benefits of an open source network management platform, the money you will spend to investigate OpenNMS through the Users Conference is a rounding error compared to the price of similar commercial solutions.

Second, OpenNMS is more of a platform than an application. I know of a number of organizations who manage billion dollar budgets using Microsoft Excel, but it didn’t work for them out of the box. They had to build the spreadsheets, integrate it with databases and other applications, but now they have a custom system that fits their needs. Most network management applications require the user to adapt their processes to fit the application. For most IT organizations those processes are what differentiate them from their competitors, so it makes more sense to use a platform like OpenNMS which can be customized to better complement them instead of the other way around.

Third, OpenNMS does have a steep learning curve. It is a broad and powerful tool but it does require an investment in time in order to realize its full potential. One way to get such knowledge would be to attend a week-long training class at the OpenNMS HQ. The cost would be US$2500 plus travel.

Contrast this with the OUCE. The full four day package runs 1000€, currently about US$1100, or less than half the price of the standard training course. Even with travel expenses (assuming you aren’t in Germany in particular or Europe in general) it should make more sense to go to the OUCE than to the usual training course (plus, the next one isn’t until January of next year). If you don’t have the need to go to the one day OpenNMS Bootcamp, it is even less expensive. It makes good financial sense.

Fourth, this is a *users* conference. If you come to training you will most likely get to listen to me for five days. At the OUCE you get to meet and talk with the people who *use* OpenNMS. Got a common problem? Find out how others solved it using OpenNMS. Got a weird problem? I can guarantee that someone at the conference will have a weirder one that they used OpenNMS to fix. The initial list of accepted talks is awesome and will only get better.

Fifth, a lot of the key people behind OpenNMS will be there as well (including yours truly) and so you can experience first hand what makes the OpenNMS community so special. Plus, since we don’t “unveil” new features, you can see first hand what is currently available in the development version of OpenNMS, including “big data” storage, new and improved graphing, elasticsearch integration and distributed polling via “minions”.

Finally, it’s a lot of fun. I can remember meeting Ian Norton during an OUCE several years ago. He had been forced to attend the conference by his (now previous) employer and was very unhappy about it. Not knowing who I was, he candidly ranted about issues he saw with the product. I assured him that we would work hard over the next two days to address them. Now he is one of our biggest supporters, and all it took was two days to “get it” and understand what makes OpenNMS so magical (in the interest of full disclosure, schnapps was involved).

In conclusion, if you are not using OpenNMS you are probably paying too much for a lesser solution. This may not be true in your particular case, but you should at least seriously investigate the possibility. It makes financial sense to do this at the Users Conference, even with travel expenses, plus you can see how real users, just like you, are getting the most value out of the tool. And even if you decide OpenNMS is not for you, you’ll have had some fun and can rest assured you did your due diligence when examining management options for your employer.

Hope to see you there.

Case Study: Why You Want OpenNMS Support

I wanted to share a story about a support case I worked on recently that might serve to justify the usefulness of commercial OpenNMS Support to folks thinking about it. As always, OpenNMS is published under an open source license and so commercial support is never a requirement, but as this story involves commercial software I thought it might be useful to share it.

We have a client that handles a lot of sensitive information, to the point that they have an extremely hardened network environment that makes it difficult to manage. They place a separate copy of OpenNMS into this “sphere” just to manage the machines inside it, and they have configured the webUI to be accessed over HTTPS as the only access from the outside.

Recently, a security audit turned up this message:


Red Hat Linux 6.6 weak-crypto-key
3 Weak Cryptographic Key Fail "The following TLS cipher suites use
Diffie-Hellman keys smaller than 1024 bits: *
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA (768-bit DH key) *
TLS_DHE_RSA_WITH_AES_128_CBC_SHA (768-bit DH key)" "Use a Stronger Key If
the weak key is used in an X.509 certificate (for example for an HTTPS
server), generate a longer key and recreate the certificate. Please also
refer to NIST's recommendations on cryptographic algorithms and key
lengths (http://csrc.nist.gov/publications/nistpubs/800-131A/sp800-131A.pdf
) ." Vulnerable

and they opened a support ticket asking for advice on how to fix it.

I had some issues with the error message right off the bat. The key used was 2048 bits, so my guess is that the algorithm is weak and not the key. The error message seems to suggest, however, that a longer key would fix the problem.

Anyway, this should be simple to fix. The jetty.xml file in the OpenNMS configuration directory lets you exclude certain ciphers, so I just had the customer add these two to the list and restart OpenNMS.

And then we waited for the nightly scan to run.

This fixed the issue with the TLS_DHE_RSA_WITH_AES_128_CBC_SHA cipher but not the first one. Nothing we did seemed to help, so I installed sslscan on my test machine to try and duplicate the issue. I got a different list of ciphers, and since openssl uses different name for the ciphers than Java, and it was a bit of a pain to try and map them. I couldn’t get sslscan to show the same vulnerabilities as the tool they were using.

We finally found out that the tool was Nexpose by Rapid 7. I wasn’t familiar with the tool, but I found that I could download a trial version. So I set up a VM and installed the “Community Edition”.

Note: this has nothing to do with open core, which often refers to their “free” version as the “community” version. Nexpose is 100% commercial. They use “community” to mean “community supported”, but it is kind of confusing, like when Bertolli’s markets “light” olive oil which means “light tasting” and not low in calories.

I had to fill out a web form and wait about a day for the key to show up. I had installed the exact version of OpenNMS that the client was using on my VM, so my hope was that I could recreate the errors.

First, I had to increase the memory to the VM. Nexpose is written in Java and is a memory hog, but so is OpenNMS, and it was some work to get them to play nice together on the same machine. But once I got it running, it wasn’t too hard to recreate the problem.

The Nexpose user interface isn’t totally intuitive, but I was able to add the IP address of the local machine and get a scan to kick off without having to read any documentation. The output came as a CVS file, but you could also examine the output from within the UI.

The scan reported the same two errors, and just like before I was able to remove the “TLS_DHE_RSA_WITH_AES_128_CBC_SHA” one just by excluding it in jetty.xml, but the second one would not go away. I found a list of ciphers supported by Java, but nothing exactly matched “TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA” and I tried almost all of the combinations for similar TLS ciphers.

Then it dawned on me to try “SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA” and the error went away. I guess in retrospect it was obvious but I was pretty much focused on TLS based ciphers and it didn’t dawn on me that this would be the error with Nexpose.

It was extremely frustrating, but as my customer was being beat up about it I was glad that we could get the system to pass the audit. While this was totally an issue with the scanning software and not OpenNMS, it would have been hard to figure out without the help we were happy to give.

It may not surprise anyone that a large number of OpenNMS support issues tend to be related to products from other vendors. Usually most of them can be classified as a poor implementation of the SNMP standard, but occasionally we get something like this.

Our clients tend to be incredibly smart and good at their jobs, but having access to the folks that actually make OpenNMS can sometimes save enough time and headache to more than offset the cost of support.

2015 O’Reilly Open Source Conference

I think this year marks the eighth OSCON I’ve attended. I’m not sure of that, but I am sure that every year I can meet up with a number of interesting people that I just don’t see elsewhere.

I used to get the conference pass so I could see the presentations, and while they tend to be of a very high quality, I often found myself spending most of my time outside of those rooms, either on the Expo floor or just sitting and talking, so this year I just got the Expo pass.

OSCON 2015 - Entrance

I have a love/hate relationship with OSCON. It seems to be skewed toward large companies, and this year was no exception.

I got to see the jugglers at Paypal:

OSCON 2015 - Paypal

(Note: Jason, who used to work with us at OpenNMS, is now at Paypal and so I get to hear about some of the stuff they are doing around open source it is pretty exciting).

and Microsoft was back with the photo booth:

OSCON 2015 - Microsoft

There were also some smaller companies in attendance. I had to go by and say “hi” to the Atlassian team as we happily use a number of their products to make OpenNMS happen, such as Bamboo and Jira:

OSCON 2015 - Atlassian

and it was nice to run into Chris Aniszczyk, the open source guy at Twitter.

OSCON 2015 - Chris Aniszczyk

I had not talked to Chris since last year’s OSCON and it was cool to learn that he’s doing well.

One thing I’ve been looking at for OpenNMS is the best configuration platform with which to integrate. It is hard to choose between Puppet, Chef, Ansible and Salt (and we should probably do all four) but if the choice was solely based on the friendliest staff Chef would probably win.

OSCON 2015 - Chef

I never did get the full story on what happened with their booth.

Right around the corner was the Kaltura booth with its incredibly shy and withdrawn Director of Marketing, Meytal:

OSCON 2015 - Meytal Burstein

She was also at CLS and our paths crossed a lot, and I’m certain I’ll run into her in the future. Oh, and if you want her opinion, you’ll have to drag it out of her.

(Note: some of the above is not true)

OSCON 2015 - CDK Global

It was also cool to see a booth for CDK Global. CDK was formed by merging Cobalt and ADP Dealer Services, and the latter uses OpenNMS. Sam (the guy in the middle) was also a Frontalot fan, so we got along well.

I spent most of my time off to the side of the Expo floor on a row I called the “Geek Ghetto”. These are booths that OSCON offers to open source projects and organizations. It was cool to see that it was almost always packed with people.

OSCON 2015 - Geek Ghetto

I got to talk to the team at the Linuxfest Northwest. This is one conference I have yet to attend but I’m going to make an effort to get there next year. I’m hoping to convince the Bad Voltage guys to come along and do a live show (they will be with us at the OUCE this September in Germany)

OSCON 2015 - Linuxfest Northwest

Next to them was a booth from the EFF. Maggie, who was at the anniversary show in San Francisco, was also doing booth duty at OSCON.

OSCON 2015 - EFF

I believe in what the EFF is doing so it was nice to get to talk with them.

Last year I spent a lot of time learning about Free Geek:

OSCON 2015 - Free Geek

and it was nice to chat with them again. If you are in a Free Geek city, you should get involved.

It was good to see a large number of women in attendance, although it was still not reflective of the population as a whole. One group working to change that is Chicktech:

OSCON 2015 - Chicktech

Note that my picture got photobombed by “Open Source Man”.

Also in the Geek Ghetto was the Software Freedom Conservancy, run in part by Bradley Kuhn and Karen Sandler. I think highly of them both and enjoyed the time I got to spend with them.

OSCON 2015 - Karen Sandler

Now, I should probably explain my shirt.

Bryan Lunduke is one-fourth of the Bad Voltage team. While I have known Jono Bacon for some time, I didn’t get to meet Jeremy Garcia or Stuart Langridge until this year’s SCaLE conference. I never got to meet Bryan. To be honest, a lot of these “meetings” happened in bars and Bryan doesn’t drink, and I did try to get his attention on the show floor but he obviously didn’t hear me.

Then I was on the Bad Voltage podcast talking about OpenNMS. This was an episode where Bryan was ill, so outside of signing in to say he couldn’t do the show, I didn’t see much of him.

Finally, we are planning on having Bad Voltage come out to the OpenNMS User’s Conference this September. Bryan is expecting the arrival of his second child, so he had to beg off.

Now I just see these things as coincidences, but the guys in the office suggested the real reason is that Bryan hates me. Jessica, our graphic designer, took the bait and made up a graphic, and my friend Jason at Princredible printed a few really nice shirts.

I wanted to meet up with him in Portland, but he was only at CLS the second day (I was there the first). He was at OSCON on Wednesday. I wandered around the Expo floor trying to find him but we could never meet up.

It started to become amusing. People would stop me and say “Bryan was just here looking for you”. After awhile I thought it might be even funnier if we never met, just circled each other at the conference and to this day we still haven’t stood next to each other (he and Jono did call me later in the day, but I had already left).

Anyway, if you think Bryan Lunduke hates you too, you can get a nifty shirt just like mine. Jason will take orders until 10 August. These are high quality shirts that are actually printed – the image is dyed into the fabric and not screened on top were it is likely to crack and peel.

OSCON 2015 - Jono Bacon

Speaking of Jono, he did an “Ask Me Anything” session and I was very eager to get some of the burning questions off my chest. Unfortunately, it was subtitled to limit the questions to things like “community management” and “leadership”. Mine were, to a fault, all obscenely biological.

I want to end this note with a picture of one of my favorite people, within or outside of open source, Stephen Walli.

OSCON 2015 - Stephen Walli

I usually only see him at OSCON, and while in his sunset years he has quieted down a bit (grin), I always welcome the time I get to spend with him.

Hope to see everyone in Austin in 2016, if not sooner.

Review: MC Frontalot with The Doubleclicks

Best OSCON after-party ever! – Satisfied Customer

Even though OpenNMS has been around for over 15 years now, a lot of people, including open source people, don’t know we exist. In an attempt to fix that, we’ve been experimenting with various marketing efforts, and in keeping with our mission statement of “Help Customers – Have Fun – Make Money” we also want them to be fun.

I have a love/hate relationship with the O’Reilly Open Source Conference (OSCON) but I can be assured that many of my friends who are into free and open source software will be there. This year I thought it would be fun to host a concert featuring MC Frontalot. Not only is his music awesome, it should appeal to many of the attendees. We lined up a venue (the amazing Dante’s) and an opening act, The Doubleclicks.

My one fear was that no one would show up, so I was relieved when I rushed from a previous meeting to Dante’s to find the place full, and by the time the show started it was packed.

Prior to setting this up, I had not heard of The Doubleclicks. Angela and Aubrey Webber are sisters who sing about geek things. Prior to the show I listened to a lot of their music, and since I was paying for this gig they even did one of my favorites, “This Fantasy World (Dungeons and Dragons)“. When they sang the lyric “and their primarily Windows-based computers” it got a big laugh.

The Doubleclicks

One thing we struggle with in the tech world in general and open source communities in particular is how to encourage more women to get involved. As a male dominated industry, women can face particular challenges. When The Doubleclicks sang “Nothing to Prove” I realized I couldn’t have asked for a better set list if I’d tried:

We read books, we played games, we made art, we watched Lost
We said things like “D20”, “shipping” and “Mana cost”
It felt good to be myself, not being mocked
Still self-conscious, though, we whispered things about jocks

But one day, you grow up, come into your own
Now geek’s not rejection – it’s a label I own
Then ignorant haters come to prove me wrong
Tell me I’m not nerdy enough to belong

I’ve got nothing to prove
I’ve got nothing to prove
I’ve got nothing to prove

This rang particularly true due to OSCON being hit with a “gamergate“-like attack for having Randi Harper speak. Considering the number of women at the show, I think we succeeded in promoting an all-inclusive environment.

After their great set, MC Frontalot and the band prepared to take the stage. This was the fourth Frontalot show I’d organized but the first with the band. The reason I hadn’t hired the whole band before was simple: it’s more expensive. Plus, from the videos I’d seen on the Intertoobz, I didn’t think they added all that much.

I was so wrong.

It’s hard to capture on video the energy these four gentlemen bring to the stage. The man driving the beat on drums is The Sturgenius (aka Sturgis Cunningham). Blak Lotus (aka Brandon Patton) is the whirling dervish on bass. I sat an watched him spin from stage left, often winding the cord to his bass around his legs and then unwinding it just in time to avoid tripping. Vic-20 (aka Ken Flagg) played wireless keytar, and while everyone was mic’d, turns out he has the voice of an angel and did the most duty on backup vocals.

MC Frontalot and Band

They played all of my favorites, such as “Critical Hit” and “Stoop Sale“, and while Front has always given 110% at my shows, being with the band brought out something more.

When I walked around OSCON inviting people to the show, a lot of people were psyched but I still got that weird “Nerdcore Hip Hop?” look from many. I don’t think that anyone who has seen them live could mistake them for anything other than truly original musical artists.

OCSON is moving to May and to Austin, Texas, next year, and my hope is to bring the band out again. And I do actually plan to write up my thoughts on OSCON itself, but as I got almost no sleep in the last week that will have to wait. The fourteen and a half hours I slept last night seemed to have helped a lot, though.

2015 OSCON MC Frontalot and Doubleclicks Party

I just wanted to post a short note about tonight’s concert.

WHAT: MC Frontalot and The Doubleclicks
WHERE: Dante’s, Portland, OR, USA
WHY: To give back to our Free and Open Source Software Friends, and to promote OpenNMS
WHEN: Doors open at 8pm, Doubleclicks sometime after 9pm, Frontalot around 10pm

If you are still reading, OpenNMS has been able to get Frontalot to perform at a number of Linux conferences, but this is the first time we’ve been able to bring out the whole band (2015 is shaping up to be a good year). So in addition to the man himself, we have Blak Lotus on bass, The Sturgenius on drums and Vic-20 on the key-tar. This promises to explode with awesomeness.

Since this is Portland, we wanted to get a local group to open and The Doubleclicks were kind enough to join us. They are the sister duo of Angela and Aubrey Webber, who will entertain with their particular brand of nerd folk. I was introduced to their work just recently, and I think it will be the perfect way to start the evening.

We also want to thank O’Reilly for continuing to produce OSCON. In many cases, it is the only time in a year where I get to see friends of mine in person, and they bring together all different type of people from the free and open source community.

Finally, last but not least is Dante’s itself. The venue was kind enough to let us schedule this free event there, and while I’ve never been, I’ve only heard great things. The only downside is that I’ve been told it is somewhat small. Since we are not selling tickets, I have no idea how many people are showing up, but from the feedback I’ve been getting from OSCON attendees, we’ll probably pack the place.

To guarantee you get to see the show, doors open a 8pm, but since some of you might still be enjoying OSCON events at that time, please note that the show won’t start until sometime after 9pm, so we hope you can make it.

Oh, if you do come and like it, please give a nod to @opennms as we are working hard to correct the fact that it is the greatest open source project you have never heard of.

See you there.

Solution for One Trackpad Issue for the XPS 13

My new laptop is the beautiful new Dell XPS 13 running Ubuntu Gnome 15.04.

It is not perfect, but it is getting close. Lightweight, beautiful screen and awesome battery life (nearly 8 hours the way I use it).

One thing that was killing me, though, was that after a certain amount of time (on the order of tens of minutes and not hours), the trackpad/clickpad thingie would start misbehaving under Gnome Shell, registering bogus clicks. There wasn’t an easy way to fix it outside of a) reboot or b) use an external mouse.

It seems that this issue has been addressed in the 4.1 kernel, so I decided to try it. I’m not sure if Ubuntu is going to support the 4 kernel series officially before 15.10 so I didn’t want to wait.

I downloaded the 4.1.1 kernel here (you’ll need three debs: the “all” headers deb and the image and headers debs for your CPU – I used “generic” and “amd64”), installed them with “sudo dpkg -i” and rebooted. The problem seems to be fixed.

But, my Broadcom wireless driver wouldn’t work. I had to download one more deb from here (via my phone – never play with kernels when you are on a long road trip), install it and now wireless is back.

Now if we could just get palm detection fixed …

2015 Community Leadership Summit

I’ve been working full time with open source software for fourteen years, and I can remember a time when we were pretty much making everything up. No one had experience with this market which most of us now take for granted, and there were a lot of questions about dealing with an open source “community” versus paying customers for open source related software and services.

Out of this arose a role, for lack of a better word, called a “Community Manager”. It doesn’t quite fit since “manage” isn’t accurate. It is hard to apply old school management techniques to a group of sometimes anonymous volunteers, many of whom you might only know by a name such as “Zaxxon476”.

One of the first people to document this role was Jono Bacon. He was one of the leaders of the Ubuntu community, one of the larger of such communities in existence. He wrote a book called The Art of Community and he also founded the Community Leadership Summit (CLS) which meets the weekend before OSCON. Due to scheduling I have never been able to be there, but OpenNMS has been a sponsor every year it has been around.

CLS - Sponsors

This year I was finally able to attend, and I wasn’t disappointed. A large, eager group of people showed up, and I really enjoyed the diversity. Not only were women strongly represented (in both attendees and session leaders) there were many people from outside of the United States.

Jono kicked off the conference:

CLS - Jono Bacon, the delicious meat

with help from another amazing fellow, Stephen Walli:

CLS - Stephen Walli, the other white meat

The format was in the “unconference” style, meaning that the attendees set the agenda. After an initial group of planned 15-minute presentations, those people wanting to host a session would write a short description on a card, get up in front of everyone and announce the session, and then go post it on a large schedule “wall” in the main hallway.

I’ve been to a number of such conferences but rarely seen such participation levels. We actually ran out of Saturday spots, but in the true cooperative style a number of people were able to combine sessions so I think it all worked out.

CLS - Schedule

The whole event had a really good vibe. It wasn’t just open source people, either. The “open source way” can be applied to a number of different fields, and it had to be stressed that in any given session you couldn’t make assumptions about the open source knowledge of the people in the room. One woman discussed how she was dealing with mental illness, and an on-line community was key to her becoming healthy. Another woman was discussing how concepts from the formal study of psychology could be applied to make communities stronger. Even proprietary companies such as New Relic were there because the user community has become key to the success of almost any technology endeavor.

I got to make new friends and catch up with old ones, so I have to admit like many conferences I spent more time chatting in the hallway than in actual sessions (as some of those session were in the hallway, I had to be reminded that my voice carries. Ooops and sorry).

For high school I went to the North Carolina School of Science and Mathematics, and I constantly run into alumni in this field. OpenNMS’s own Seth Leger went there, as did Spot Callaway and Gina Likins from Red Hat. I got a cute picture of Gina (pronounced “Jenna”) with Ulf.

CLS - Gina Likins

It looks like the second day might even be stronger than the first, but unfortunately I won’t be able to make it. As OSCON is moving to Austin next year, it will be interesting to see how that changes CLS, and I plan to make every effort to be there.

Adventures in Open Source

The EFF Turns 25

In 1990, when the Internet was much smaller and slower than it is today, a bunch of forward-thinking people realized that this new technological wonder would create some unique issues for our society, and they formed the Electronic Frontier Foundation to protect people from its negative effects.

I can’t remember the first time I got involved with the EFF, but for years I’ve followed their efforts and cheered them on. Before I wore it to shreads, my “Protect Bloggers Rights” T-shirt was one of my favorites, and I still carry my passport in an EFF-badged wallet that blocks RFID transmission.

Earlier this year, the animator Chad Essley auctioned off the chance to be added to his video for the MC Frontalot song “Shudders” with all proceeds going to the EFF. The result was that the OpenNMS mascot Ulf gets a few seconds of much deserved fame and I got an invitation to the EFF’s 25th anniversary party.

I wasn’t going to make it (I don’t live in the Bay Area) but when I decided to attend this week’s Community Leadership Summit followed by OSCON up in Portland, it turned out that it wasn’t much more expensive to fly here first before heading up to Oregon. I know several people in the area and I figured I could find something to do before the party, but then the EFF created a half-day “minicon” so I decided to attend that as well.

EFF - DNA Lounge

The minicon consisted of three panel discussions. It was held at a nightclub called the DNA Lounge and when I got there just before noon the line to get in was already stretching down the block. When I did get in, there was a stage set up for the panels (a moderator’s podium and a table with four chairs for the panelists) as well as two banners describing what the EFF does.

EFF Banner

I thought the left one was pretty succinct: Free Speech, Privacy, Innovation, Transparency, Fair Use, International. Yup, that about covers it.

I didn’t take any pictures of the attendees (this group does attract a contingent from the “black helicopters” crowd) so while I probably had the right to take pictures as part of a public gathering it would have been rude. It was nice to see a fairly even split between men and women, and for once I wasn’t the oldest person in the room. It was mainly Caucasian and Asian faces that I saw (hey, that’s pretty much Silicon Valley) and I did see people with colorful hair (bright pink, electric blue, etc.) That part was similar to the open source conferences I attend, but there wasn’t a single utilikilt. The vibe was also different. Whereas FOSS conferences also attract technical people with a strong libertarian bent, this crowd included a lot more people concerned with social activism.

Which brings us to the first panel: Activism.

EFF - Panel 1

Not only does the EFF identify threats to liberty brought on by new technology, one of their pillars is to mobilize people to effect change, so this panel discussed ways to more effectively do just that. Should you call your Congressional Representative or e-mail them? Is publicly tweeting about them better than a private correspondence? One panelist commented on the fact that you can’t A/B test reality so it can be hard to determine the best action. Plus, if a particular effort is successful, such as with SOPA, the bar is set high for the next one, which can cause its own problems.

It was the first time I had been introduced to Annalee Newitz, and I really liked her comments. Yet another person to follow on the Twitters.

They also announced a project by Sina Khanifar called democracy.io which is supposed to make it easier for people to contact those in government.

The second panel focused on Copyright.

EFF - Panel 2

I am not an anti-copyright person. Copyright law is what makes free and open source software possible. However, it is obvious that it is broken. As a process created to mainly protect things like the written word, it doesn’t lend itself well to computer code. Plus, some copyright holders have a track record of abuse. I’ve even experienced it in such things as bogus DMCA takedown notices.

Part of this discussion focused on the concept of “fair use”. If I am given something or I pay for something, does the person from whom I got that something have a right to set limits on what I can do with it? It’s a tricky question. If I use someone’s song in a television commercial, it seems obvious that I should have to pay the owner of that song, especially since it may imply that the creator of the music endorses my product or service. But what if I invite 30 people over for a party and put on some music? Does that count as a “public performance”? It’s tricky.

The EFF is very concerned with transparency, and quite naturally has issues with secret negotiations such as the Trans-Pacific Partnership agreement (TPP). Proponents of keeping trade negotiations secret will claim that they don’t want the discussion to disrupt markets. For example, if the discussion was about whether or not to place tariffs on corn exports, whether or not they would actually come about, this could cause undue fluctuations in the market for corn.

As one of the panelists noted: Copyright is not corn.

The TPP has a focus on intellectual property rights which will have far reaching repercussions for users of technology. Without oversight, the government’s zeal to protect, say, the movie and music industry, may result in actions that are detrimental to end users. People in government don’t tend to have strong technical experience, so it is important that these discussion take place in the open.

Privacy was the topic of the final panel.

EFF - Panel 3

This panel included Bruce Schneier. This was the first time I had seen him speak, and I was not disappointed. One of the questions was to predict privacy challenges due to technology 25 years from now. Bruce pointed out that it was harder to predict the impact of new tech on society than the tech itself. For example, we now have flying robots that kill people. On the one hand this is very frightening, and on the other hand, in a way, it is really, really cool.

He was referring to drones of course, and I couldn’t help but think of the trauma some drone operators are now facing even though they are thousands of miles from actual combat. Tech has also created an “interrupt driven” culture that may be fostering short attention spans. Heck, I’ll be surprised if even one of my three blog readers makes it this far in this long post, and we’ve had to come up with tags like “TL;DR” to deal with things like this. I can’t imagine what changes this will bring about in 25 years.

I was also impressed by panelist Parisa Tabriz. She is the “Security Princess” at Google and a solid public speaker. She pointed out that at Google they sometimes struggle with security versus privacy, in that certain security tech can leave a fingerprint that might weaken anonymity.

It is hard to talk about Google without bringing up Apple, and it was pointed out that Apple fails miserably on the transparency front but does do a good job when it comes to privacy. The argument goes that since Apple makes money on hardware (compared to Google’s model) they have less motivation to look at their users’ data. It would have been nice to have someone from Apple on the panel, but I’m not sure if they were asked. I did ask the EFF via a tweet, but didn’t get a response.

While most panel discussions suck, I enjoyed these, and I’m glad I went. The minicon ended around 4pm and since the party didn’t start until 8pm I decided to head back to the hotel, work on some e-mail and take a nap.

That was a mistake.

When my alarm went off at 7pm, I was so tired I considered blowing off the party entirely. I decided to go because Maggie had managed to find another RFID blocking passport wallet, as my EFF-branded one is pretty tattered, and I need another. It doesn’t have the EFF logo on it, but I hope they make more in the future.

EFF Passport Holder

My passport has had RFID technology embedded in it for years, but in all my travels it has never been legitimately accessed. It is just another example of technology being chosen because it exists without a firm plan on how to use it. I like knowing that I now can chose when to enable it or not (and yes, I know I could nuke it in the microwave but I’m not ready to go that far, yet).

Another thing I wish the EFF would do is advertise more about Amazon Smile. If you shop on Amazon Smile you can choose to have a portion of your purchase benefit a specific organization. It doesn’t cost you anything, and while I can’t find an actual total, since I shop on Amazon a lot I feel that I’ve probably sent a significant amount of money to the EFF. Of course, I can’t imagine that they are happy with things like Amazon Echo, so perhaps there is a conflict of interest, but I still wanted to make people aware of it.

EFF - Party Stage

So, I grabbed an Uber, went to the party, met Maggie and got my new passport holder. I then made a pass around the club but didn’t really feel comfortable. These were my people but then again not my people. It was obvious many knew each other, and while I’ve never been one to have a problem with a room full of strangers (in most situations I make new friends) the environment was pretty loud and not conducive to conversation. I just didn’t have the energy so I left.

This means I missed seeing Wil Wheaton and Cory Doctorow, two more people I’ve never seen in person but would like to one day. From social media it seems like it was a good time, but I just wanted to grab some dinner and sleep.

EFF - Wil Wheaton

Overall, I had a good time with the EFF. It is rare that I agree with everything even people I like do, but I can’t think of something the EFF has done in the last 25 years that bothered me or pissed me off. It is one of the few organizations that I regularly donate to, and I plan to leave them some money in my estate (if there is any left, I also plan to live for another 100 years and die after I’ve spent my last dime). If you haven’t supported them yet, I’d like to suggest that you do so.

Today I’m off to Portland for the CLS and OSCON, and these really are my people. I’ll let you know how it goes.

Uber vs. Taxi

Back in 2012, I first experienced Uber. While I assume everyone knows what Uber is, just in case you don’t, it is a ride service that heavily leverages modern technology to disrupt the livery/taxi industry.

When I first used Uber in 2012, it was limited to “black cars”, vehicles like Town Cars on the higher end of the scale, and the price reflected it. Now they have a number of different options, such as UberX (similar to a taxi), UberPool (more of a ride share version of UberX), UberSushi, UberMusic, etc. (okay, I made the last two up).

I had a rather positive experience with Uber back in 2012, but I rarely had the chance to use it much after that. Later, when I started reading about some “evil” things they were doing, I wasn’t inclined to call on them when I needed a ride, and their Android app seems to need an awful lot of permissions in order to work correctly, so I wouldn’t install it.

I am currently spending a few days in San Francisco, and when I landed at SFO I decided to take a taxi instead of BART. I like BART, but I was running late and also had a fairly large suitcase with me, so I opted for the convenience of a cab.

It was a bad experience.

When I approached the cab stand, I was assigned the next cab in line. This was car 226 from “Veteran’s Cab Company” and it was a very tired Toyota Prius. The driver seemed more interested in listening to music on his phone and texting than getting me to my hotel.

Texting Taxi Driver

He repeatedly ignored my requests that he not text and drive, and as I was watching for the best routes on Google Maps, he also ignored my requests to take me on the faster route. Outside of putting my life in danger, he probably cost me an extra $10 and an extra 15 minutes.

I did survive the trip, and I checked into the hotel, dropped my bags and headed back out because I was meeting a friend and we were going to take BART to the East Bay.

Although her house was only a 10-15 minute walk from BART, she was in heels and decided that we would catch a ride with Uber. This was UberX. The driver was waiting for us in an immaculate Prius and promptly took us to the house. As I ended up staying there past the time that BART stopped running, they called me another UberX ride to take me back to the hotel. This was also in a Prius, clean, and the driver was very friendly and safe.

It is hard to express the stark contrast between the experience of a normal taxi versus Uber.

I was in town for the EFF’s 25th anniversary party. While I walked to the “minicon” they held during the day, I decided to take Uber to the evening party. I dusted off my Uber account, updated the credit card, and called for a ride.

Within three minutes Ye showed up in a nice Toyota Camry. The route to the DNA Lounge was already in his phone, adjusted to avoid traffic, and the trip was quick and pleasant. As everything is paid for via the app, I had nothing to do but enjoy the ride.

I can see why people could get used to this.

For the ride back, I used Uber again. This time Allam picked me up in a Honda CR-V. Again, he arrived within three minutes. I was his first customer for the night and we hit it off to the point where I didn’t want the ride to end (he was originally from the West Bank of Israel and we talked a lot about the Middle East, which I’ve enjoyed visiting).

When I go to the airport tomorrow to head to CLS and OSCON, I plan to take UberX, or I might try UberPool.

While I still have concerns about some of Uber’s policies, and I probably need to check out Lyft (a competing service), we are talking about an experience that is orders of magnitude better than the old status quo. I’ll be hard pressed to take a taxi again.

Adventures in Open Source

The OpenNMS Calendar

As I was spending this morning trying to get organized, I thought it would help me to post some of the OpenNMS events coming up over the next few months.

July: OSCON

The O’Reilly Open Source Conference, being held the week of 20 July in Portland, OR, USA, is probably the last great commercial open source conference. I’ll be there on the Expo floor and would love to chat with folks about OpenNMS and open source. We are also sponsoring a free concert with MC Frontalot and the Doubleclicks at Dante’s on Thursday night the 23rd:

August: Training

We are holding our formal week-long OpenNMS training course the week of 10 August at OpenNMS HQ in Pittsboro, NC. This is the best way to get up to speed with OpenNMS, plus you get to meet a lot of the people who make it happen.

September: Users Conference

This year’s users conference is shaping up to be the best yet. It will be held from 28 September to 1 October at the University of Applied Science in Fulda, Germany, which is just outside of Frankfurt.

Sponsored by the independent OpenNMS Foundation, The Call for Papers is still open. Also this year we’ll have the gang from the Bad Voltage podcast doing a live show for your entertainment.

October: All Things Open

From 18-20 October, the All Things Open conference returns to America’s Open City: Raleigh, NC (home of Red Hat). This is a great time and OpenNMS will be a sponsor this year.

Hope to see you at one or all of these events.

2015 Mini Dev-Jam

So, after this year’s Dev-Jam, several people followed us back to Pittsboro. Markus von Rüden, Ronny, Christian and Dustin all came to visit, as did Antonio. It was an extra week to get even more work done and a chance for us to socialize.

On Thursday Ben suggested we visit a really nice Japanese restaurant called Dashi in Durham. While downstairs serves noodles, upstairs is a bar with small plates. We rented the place out for a few hours.

Dinner at Dashi

It was excellent. The food was delicious and unusual, and the drinks were splendid as well.

Since our guests weren’t leaving until July the 5th, it was only appropriate to have everyone over to celebrate July the 4th. I was finally able to make Fish House Punch (there is so much of it you need a large number of people to help drink it) and we did the usual 4th of July things such as cooking out on the grill.

The one thing we couldn’t do was fireworks, as there are pretty strict limits on them in North Carolina. I thought we could substitute a bonfire (I generate a lot of stuff to burn on the farm) but with the large amounts of rain we have been getting it really wouldn’t catch.

Then Jesse asked “Do you have any gasoline?”

Against my better judgment, I got some gas and while it improved things, the fire still wasn’t blazing like a bonfire should. Then someone suggested I get the leaf blower.

Tweet about the 4th party

Now, I have a really nice leaf blower. It’s a four-cycle Makita that makes me feel like Magneto. It did the job.

4th of July Bonfire

Remember, don’t try this at home.

Speaking of home, everyone made it back safely. It was nice seeing them for an extended period of time.

The next chance I get to see old friends will be OSCON coming up in two weeks. Remember that OpenNMS is sponsoring an MC Frontalot concert with the whole band at Dante’s on July 23rd. Hope to see you there.

Linux Mint 17.2 “Rafaela”

Just a quick post as I’ve now upgraded two desktops to the latest Linux Mint, version 17.2, code named “Rafaela”.

The upgrade process was pretty painless. I was on 17.1 “Rebecca” so I made sure all the packages were up to date. Then I launched the “Update Manager” application and chose “Upgrade to 17.2″ under the “Edit” menu.

Easy-peasy.

I haven’t seen any new issues and some of the old ones seem to have disappeared. I used to have issues with a) the desktop background going all wonky, b) the screen resolution dropping down to 640×480 that was only fixable via reboot, and c) the screen not being responsive at all, necessitating Ctl-Alt-Fx and then back to Ctl-Alt-F8. No biggies and they were pretty infrequent, so I’m not certain they are fixed (I have an ATI Radeon PRO card in the desktop with the issue) but I haven’t seen them since the upgrade.

Plus, yay!, the screensaver is back. Ubuntu decided a long time ago to basically nix the screensaver and just power off the screen. I like screensavers, but I also like an integration with the desktop environment so I never hacked in xscreensaver. Well, in 17.2, they did. You will have to install the xscreensaver packages to get choices (well, more than the default two) and it is missing a randomizer (sniff) but one step at a time.

I just wish I could get the clickpad to work correctly on my new laptop. I’ve posted my problem to the forum but so far no suggestions.

Anyway, I’d recommend Mint users upgrade when able. So far so good.

Update: Problem a) is still happening. When the system comes back from a suspend the desktop background is distorted into squares of mainly black and white pixels. I have to change the desktop background away from what it is and then back to restore. Doesn’t happen on my NVidia desktop.

2015 Dev-Jam: Day Five

Sorry for the week delay on this post, but this happened.

The last day of Dev-Jam is always bittersweet for me. I’m sad that it is over, but I also get to see all the wonderful “new shiny” people have been working on. Friday we do demos.

This year we made an attempt to record each demo. Just click on the picture to see it on the YooToobz. Videos, yay!

First up was Ben. Ben is the architect of our new mobile app, OpenNMS Compass. Available for both iOS and Android, it may even turn into our next overall user interface. To do that, it needs graphs, so Ben demonstrated how you can now display graphs in Compass. You can even set “favorites” so they show up on your main screen.

Dev-Jam Demos: Ben

Markus von Rüden spent the week working on something fun: digitizing our mascot and kiwi overlord, Ulf. He demonstrated this work in a game. While it wasn’t completely finished, when Ulf died would he split in half to reveal a kiwi (fruit) center. Cute. Unfortunately, no video and no wiki page (yet).

Dev-Jam Demos: MvR

Christian presented a new way to represent issues within OpenNMS, a “heat map“. It works with both alarms and outages.

Dev-Jam Demos: Christian

Jesse presented something that literally gave me goosebumps. Using our new integration with Newts, you can search for similar data within OpenNMS. So if there is say, a spike, you can search through all the other metrics to see if there are other data sources that spike at the same time.

Dev-Jam Demos: Jesse

David S. presented a new northbound interface for sending alarms to other systems via JMS. He used ActiveMQ as a proof of concept.

Dev-Jam Demos: David S.

Ron created a couple of new features. The first was the ability to see polls as events, including how long each poll took (if available). He also added the ability to create a consistent color scheme across performance graphs.

Dev-Jam Demos: Ron

Umberto created another real exciting feature – the ability to export in real time OpenNMS events to Elasticsearch. Since OpenNMS can handle thousands of events a second, sending them to a system built to analyze such data could be very useful. Umberto was sponsored to attend by the OpenNMS Foundation.

Dev-Jam Demos: Umberto

A second OpenNMS Foundation attendee was Marcel. He worked on improving data collection for Fortinet devices.

Dev-Jam Demos: Marcel

Another cool feature was Dustin’s custom data collection script tool. Sometimes OpenNMS gets criticized for not using SSH to collect data and perform montoring. The reason it doesn’t is rather simple: it’s a stupid idea. It usually requires that you set up keys with null passphrases, and often they connect as root. Despite the security issues, it is also a resource hog and can’t scale. We have always recommended using an extensible SNMP agent like Net-SNMP, but it can be some effort to set up.

Dustin’s feature allows you to put collection scripts in a special folder on the server, and OpenNMS will automatically collect the data. All you need to do then is to add a graph definition and you’re done.

Dev-Jam Demos: Dustin

Ronny discussed running OpenNMS in Vagrant and Docker containers. Neato.

Dev-Jam Demos: Ronny

DJ was frustrated in how long it can take to compile OpenNMS if tests are enabled. OpenNMS is heavily instrumented with software tests. These can be broken into “unit” tests and “integration” tests. Maven (the build system used by OpenNMS) can be configured to separate them. Since unit tests should be small and quick, they can be run every time with the integration tests only run for regression.

Dev-Jam Demos: DJ

Finally, Seth presented the work he did this week which was focused on changes needed to support OpenNMS Minion. Minions are little, stand alone processes that can perform basic monitoring and data collection, which is then forwarded up to an OpenNMS Dominion instance.

Dev-Jam Demos: Seth

While the last Dev-Jam always seems to be the best Dev-Jam, I think it was true this year. This work will go along way toward positioning OpenNMS for the coming Internet of Things, and as always it is amazing to see what brilliant people can do when given the opportunity to work together.

We ended the day at Surly Brewing Company. The beer was delicious and the company stimulating. I only got one non-blurry picture, and unfortunately my pants fell down when I stood up to take it.

Dev-Jam: Surly Brewing

Sorry.

I hope to see everyone at the OpenNMS Users Conference in September. I promise to keep my pants on.

OpenNMS Foundation Europe

DevJam 2015 Demos

The basic idea is put a bunch of smart good looking people from the OpenNMS community in one room, take care about fun, food, sleep and see what happens. We had this year 27 people from the U.S. and Europe to spend one week in our adventure to Open Source. Special thanks to Mike Huot, his family and The OpenNMS group to make this event happen. We had also the first time two community members sponsored by the OpenNMS Foundation at the conference. This year was amazing and we had a small demo session on the last day. Here are the videos if you are interested and can wait until next years DEVJAM!!!

Code refactoring with Seth Leger

Unit Test improvements with DJ Gregor

Vagrant and Docker with Ronny Trommer

Performance data correlation with Jesse White

Script data collection with Dustin Frisch

Adventures in Open Source

Review: Dell XPS 13 (9343) Ubuntu Edition

Okay. When it comes to tech, I want the latest and greatest. To me, the “greatest” must include as much open software as possible. As an ex-Apple user, I want the same experience I used to get with that gear, but with free and open source software.

It can be hard. Rarely is the open source world involved in new hardware decisions by the major vendors, so we learn about new devices after the fact. Thus there is an inevitable delay between when a product is announced and when it properly works with FOSS.

Such was the case with the new XPS 13 laptop from Dell.

Now, I vote with my wallet, so back in 2012 when I needed a laptop I bought the second edition “Sputnik” Dell XPS 13, which shipped with Ubuntu. It served me well for many years and currently runs Linux Mint 17.1 with no problems. When the latest edition XPS 13 was announced, I immediately ordered it, but it didn’t work out so well.

When I discovered that the other option from Dell, the M3800, wasn’t for me, I decided to wait until they officially supported Ubuntu on the new XPS 13. I didn’t have to wait long, and I placed my order the day I learned it was available (I was happy to learn that they had to fix some kernel-level issues and it wasn’t just me).

Why didn’t I wait longer? The XPS 13 is gorgeous. I haven’t felt this strongly about a laptop since my 12-inch Powerbook back in 2013. Others seem to agree, with even Forbes praising this machine.

Anyway, the order process was simple. I got the XPS 13 with the i7 processor, 8GB of RAM, 512GB SSD and the HiDPI touchscreen. The laptop arrived about a week before it was scheduled. Go Dell.

Now for the obligatory unboxing pictures. The outer box arrived undamaged:

Dell XPS 13 Unboxing Pic 1

The laptop itself came in a separate box:

Dell XPS 13 Unboxing Pic 2

with the accessories shipped in a cardboard “square tube”:

Dell XPS 13 Unboxing Pic 3

While the small power supply came with a longer power cable with a “mickey mouse” connector, the XPS 13 comes with a small adapter that gets rid of the cable entirely (like the Apple laptop power bricks).

Dell XPS 13 Unboxing Pic 4

The laptop pretty much fills up its box:

Dell XPS 13 Unboxing Pic 5

Like with my original XPS, there is a cool little intro video that plays when you first start it up:

Please note that it only runs on the first start – you will not have to wait 40+ seconds to boot your system (usually less than 10).

The XPS 13 Ubuntu Developer Edition ships with 14.04, but I had some issues with it. First, it didn’t have the option for encrypting the home directory. I’m not sure how or why that got removed. The system also crashed when I attempted to make a backup image to a USB stick. Finally, there are apparently still outstanding issues with 14.04:

Ubuntu 14.04 includes kernel 3.13. The touchpad will run in PS2 mode and the soundcard will run in HDA mode. Currently (4/15) out of the box the HDA microphone will not work, and you will need some packages from the factory shipped image to make it work properly.

While I knew I was going to base the system, I logged in to the stock image to check out the apt repository. There really wasn’t anything outside of the vanilla Ubuntu (the few Dell packages seem to be just for recovery) so I felt fairly safe in reinstalling.

I immediately went to my default distro, Linux Mint 17.1, but found that a lot of things, especially the touchpad, didn’t work as expected. It did handle HiDPI screens just fine (you could actually see the mouse pointer increase in size when logging in). I figured I’d wait until 17.2 comes out and try it again.

On a side note, I don’t know why it is so hard to get a decent touchpad under Linux. We’re getting closer, but still, it tends to be the weakest point of the Linux laptop experience.

In search of a solution, I found Barton’s Blog and read the following:

With BIOS A00 or BIOS A01 the touchpad will run in I2C mode and the sound will not function. Please update to at least BIOS A02 and the touchpad will run in I2C mode and the sound in HDA mode. (4/15) All of the relevant patches have been backported and all functions will work out of the box.

I really liked the “will work out of the box” bit, so I installed Ubuntu 15.04.

It had been awhile since I’d used Unity, and it has really matured. I especially liked the little touches. When I changed my desktop background, the background of the Dock changed color to match it. Neat.

Where Unity still has some way to go is in HiDPI support. There is a scaling factor you can set, but it only applies to a small part of the UI. I still ended up having to customize many of my apps. For example, if you look at the settings page with scaling, a lot of the text under the icons are cropped:

Dell XPS 13 Ubuntu Text Cropped

Not a show stopper, and I used it for over a month without getting too annoyed.

Last week I saw that the release candidate for Mint 17.2 was out, so I dutifully backed up my Ubuntu install, based the system and installed Mint. Things seems to work better (although HiDPI support was not working by default), but I ran into a weird problem with trying to click and drag.

While everyone seems to deal with trackpads differently, the way I click and drag is to use the index finger of my left hand to click and hold the lower left corner of the trackpad, and then I use the index finger of my right hand to move the mouse pointer. This works fine under most desktop environments, but under Cinnamon it seems to interpret it as a right click (which usually causes a menu to drop down). If I just used a single finger to click on the window header and then move it, it worked as expected, but I couldn’t get used to it enough to continue to use it.

Oh well. I’ve posted a question on the Mint forums but no one has been able to help.

Anyhoos, since my system was based I decided to try out some other 15.04-based distros while I had the chance. I had heard great things about the new Plasma interface in KDE, so Kubuntu was next.

I can’t say much about Kubuntu since its HiDPI support is worse than Unity. Everything was so tiny I couldn’t spend much time in the UI. Oh well, what I saw was pretty.

And I should stress that this was a recurring theme in my experiments with desktop environments. Every UI I’ve tried has been beautiful and more than able to compete with, say, OS X.

By this point I decided to punt and just search on “Linux Desktop HiDPI”. Several of the results touted that Ubuntu Gnome was the best desktop to use for HiDPI systems. So, before going back to Unity I decided to give it a shot.

Wow.

I haven’t used Gnome 3 in awhile, but I was encouraged in that even the install process handled the HiDPI screen well. It has become really mature, and so far has provided by far the best experience with the XPS 13. I’ve had to do little to get it to work for me.

Is it flawless? No. There is an issue with the touchpad where it occasionally translates touches into click (kernel patch approved). If you sleep the system, the touchscreen will stop working (but you can reload its module). Sometimes, the system doesn’t sleep when you close the screen, which can cause the laptop to get really, really hot.

But these are minor issues and I expect them to be addressed in the near future. I am confident that I’ve found a great combination of software and hardware, and that it will only get better from here.

I have just a few more notes to share. The battery life is outstanding – I can get 6-7 hours of use without recharging. The “infinity screen” is beautiful and bright, but by having almost no bezel they had to move the camera to the lower left corner, which creates a slightly odd viewing angle.

In closing, here are a couple of shots comparing the XPS 13 with the M3800.

2015 Dev-Jam: Day Four

Since I sincerely doubt even my loyal readers get to the bottom of my long posts, I figured I’d start this one with the group picture:

Dev-Jam Group Picture

That antenna behind Goldy’s head is part of Jonathan’s project to use OpenNMS to collect and aggregate FunCube data from around the world. Can I get an “Internet of Things“? (grin)

There is this myth that just by making your software open source, thousands of qualified developers will give up their spare time to work on your project. While there are certainly projects with lots of developers, I am humbled by the fact that we have 30-40 hard core people involved with OpenNMS.

Unless you’ve gone through this, it is hard to understand. At one time, OpenNMS was pretty much me in my attic and an IRC channel. Luckily for the project that didn’t last long. My one true talent is getting amazing people to work with me. Then all I have to do is create an environment where they can be awesome.

It’s why I love Dev-Jam.

I also love pizza. Chris at Papa Johns was kind enough to send us some free pie for dinner:

Dev-Jam Pizza

Today we spent time talking about documentation. Documentation tends to be the weak point of a lot of software, and open source software in particular. The Arch Linux people do about the best job I’ve seen, but even then it is hard to keep everything current. For over a year now a group of people has been working very hard to improve the documentation for OpenNMS, and the new documentation site is most excellent.

It does take a little time to understand the navigation. The documentation is included in the source and managed on GitHub, so there is a new version for each release. But just as an example, check out the Administrator’s Guide for 16.0.2.

Written in AsciiDoc, it is now the best place for accurate information on how to use the software. We also want to extend a special thanks to the Atom project for creating the editor used to create it.

One of the things we discussed was how to deal with the wiki and the .org website. It’s not practical to duplicate the AsciiDoc information on the wiki, so the plan is to include the relevant part from the documentation in something like an iframe and use the wiki more for user stories. The “talk” page can then be used for suggestions on improving the documentation, and once those suggestions are merged they can be removed.

I had suggested that we make the wiki page the default landing page for the .org site, but Markus pointed out that we need to do a better job of marketing OpenNMS, and the landing page should be more about “why to use OpenNMS” versus “how”. I had to agree, as we need to do a better job of marketing the software. My friend Waleed pointed out in Twitter this weakness:

Twitter Comment 1 from Waleed

Twitter Comment 2 from Waleed

To better educate folks about why OpenNMS is so amazing, we are considering merging the .com and .org sites and using the .com WordPress instance for the “why you should use OpenNMS” with a very obvious link to the wiki so people can learn how to use OpenNMS. Part of me has always wanted to keep the project and commercial aspects of OpenNMS separate, but it then becomes really hard to maintain both sites.

In case you haven’t guessed, we do spend a lot of time thinking about stuff like this. (grin)

Dev-Jam Thursday

A lot of other cool stuff got done on Thursday. DJ announced that he had separated out the unit tests in OpenNMS (for features) from the integration tests (for regression). OpenNMS has nearly 7,000 junit tests (and growing). It’s the main way we insure that nothing breaks as we work to add new things to the software. But with so many tests it can take a real long time to see if your commit worked or not. This should make things easier for the developers.

It’s hard to believe that Dev-Jam is almost over. Luckily, it sets the stage for the next year’s worth of work. Since our goal is nothing less than making OpenNMS the de facto network management platform of choice, there is a lot of work to be done.

Adventures in Open Source

Review: Nexus 6

As most of my three readers know by now, I was a big fan of the OnePlus One handset until I experienced their customer support (which seems intent on covering up a major defect in the touchscreen of their devices).

So, it was time to get another smart phone. Andrea had been using a Nexus 6 for awhile, I thought the phone might be too big for me. The phone is huge.

David pointed out that the OnePlus was huge compared to my previous HTC One, and it only took me a day or so to get used to that size change, so I’d probably feel the same way about the Nexus 6.

He was right.

I ordered it from the Play Store and it showed up a couple of days later. The name of the phone was actually on the bottom of the box:

Nexus 6 Unboxing Pic 1

and once I cut the “tape” I flipped it over so I could open it.

Nexus 6 Unboxing Pic 2

The phone sits in a little cardboard cradle

Nexus 6 Unboxing Pic 3

and if you remove it you can see a little packet with documentation.

Nexus 6 Unboxing Pic 4

Under that is a high amp charger and that’s about it.

Nexus 6 Unboxing Pic 5

The phone has a gorgeous display and its six inch screen is big enough that I can watch movies on it, so I loaned my Nexus 7 (that I used to use when traveling) to Ben so he could play with OpenNMS Compass on Android.

Nexus 6 Specs

It’s also blazingly fast, but all that power does come with a price: battery life. With the OnePlus I could easily go a day, even with playing Ingress to some degree, the Nexus 6 needs a little more juice. It is in no way horrible, and is much better than the HTC One, but it is still a factor. I just ended up buying a TYLT wireless charger for my desk so I can sit the handset there all day and it stays charged (yay wireless charging).

I did buy a case for the phone but that pushed it over the size limit for even my large hands. Caseless, I was worried about dropping it, so I bought a “grip” pad that sticks to the back and makes it feel less like a slippery bar of soap. So far so good.

The best thing is that, thanks in large part to Jake Whatley, I can now put OmniROM on it. It was a pretty simple process to unlock the phone using adb, install TWRP and then flash the latest OmniROM nightly. I was surprised at how much my Android experience was truncated by the stock ROM. I couldn’t shake my phone to dismiss an alarm or augment the power menu to add options like a reboot instead of just powering off. So far no problems.

The size of the Nexus 6 will be off-putting for some, but it is about the same size as an iPhone 6 Plus, so perhaps not.

Nexus 6 vs. iPhone 6+

As I was investigating alternative ROMs for the Nexus 6, I thought it was funny when I found out the code name for the device. Nexus devices tend to be named after fish.

The code name for the Nexus 6? Shamu.

Review: LG Watch Urbane

Even though I am no longer a user of Apple products, I was eagerly awaiting the release of the Apple Watch. Why? Because Steve Jobs had a way of making stuff for me that I didn’t know I wanted. While I’ve owned an LG G Watch R for awhile now, the experience hasn’t been life changing (unlike using an iPhone was) and so I was looking for Apple to really “wow” me.

My friend Ben (who knows more about Apple products than anyone I know) thinks I’m more critical of Apple than the fiercest “fanboi” and he’s probably right, so I want to make sure to expressly state that I haven’t used an Apple Watch so anything I say about it needs to be taken in that context.

However, Matthew Inman, another person whose opinion I respect, recently did a comic on his experience with the Apple Watch, and his experience is very similar to mine with Android Wear. It’s interesting, it has potential, but it isn’t life changing … yet.

To me, my watch is like having a second screen on my phone. Remember when people first started getting dual monitors? It’s like that – it makes me more productive when using my phone but it is more of an extension than a feature in and of itself.

The main thing my watch gives me is a socially acceptable way to keep up with notifications. If I’m in a meeting, or at a meal, or in any other social situation where pulling out my phone and looking at it would be rude, I can glance at my watch and see if I need to address that text or e-mail.

The main difference between Wear devices and the Apple Watch is that the latter has a crown that spins and can be used scroll the display. Inman points out that he doesn’t use it, and so you are pretty safe choosing the smart watch you like that works best in your digital ecosystem.

The main thing I want from a watch is a stylish accessory that actually looks like a watch. Enter the LG Watch Urbane.

Urbane Watch Face

After my horrible experience with the OnePlus One phone, I was shopping for a replacement handset when I came across the Watch Urbane. I fell in love immediately.

I got the G Watch R because it looked like a watch and not a slab of glass. The Urbane takes that experience to a new level by adding a rose gold bezel and a nice leather strap. The display is amazing. The default watch faces are amazing. In short it is the perfect evolution for my favorite smart watch to date.

It’s a powerful watch with great battery life. While I tend to charge it overnight, I can get over two days of normal use out of it easily (I’ve had to test that when flying overseas).

Urbane Specifications

I bought it on Amazon, and it showed up protected in a rather easy to open plastic cover:

Urbane Unboxing Pic 1

The box was similar to other mechanical watches I have bought:

Urbane Unboxing Pic 2

and opening it immediately revealed the watch:

Urbane Unboxing Pic 3

The band was a little stiff at first, but after wearing it for a day or so it softened up a bit.

Urbane Unboxing Pic 4

It came with a number of accessories. Like the LG G Watch R it requires a charging cradle that is powered via a microUSB connector.

Urbane Unboxing Pic 5

The Urbane was one of the first watches to ship with the Andoird Wear 5.1.1 update that allows for such things as talking to the phone over Wi-Fi, but about a day after I got the watch the update was generally available for other devices, including my G Watch R.

Urbane vs. G Watch R

The Urbane is a little smaller, and while I liked the “tick” marks around the outside of the G Watch R, so many watch faces include them due to the popularity of the Moto 360 that I was happy to see them removed on the Urbane (having two sets of tick marks is a little cluttered).

While I still wear the G Watch R if I’m going to be active (i.e. sweating), the Urbane is my go-to wrist accessory. I am constantly getting compliments on it, and I think the biggest problem LG has is that no one has heard of it.

Perhaps this post will help.

2015 Dev-Jam: Day Three

It’s hard to believe that this year’s Dev Jam is half over. It seems to take forever to get here and then it is over too soon.

Lots of cool stuff going on. David Schlenk has written a Java Message Service (JMS) northbounder interface. While targeted at Apache ActiveMQ, it should work with any JMS provider, and it is another great tool to have for the OpenNMS platform.

Christian did a cool little hack using a Blink(1) USB light. If you have a Blink(1) you can plug it into your laptop and then run a little Java app. The app will connect to your OpenNMS instance and then the color will change based on the severity of alarms. Cool.

Dev-Jam Key Blink(1)

I also participated in my first GPG key signing. Jeff organized it to increase our “web of trust” and once I got into it, it was kind of fun.

Dev-Jam Key Signing

He promised cake, and for once the cake wasn’t a lie:

Dev-Jam Key Signing Cake

The cake went well with dinner, which came from the always amazing Brasa:

Dev-Jam Key Brasa

Most of us ate out on the deck. This is the view looking out toward the Mississippi:

Dev-Jam View

While we have held Dev-Jam in locations other than UMN, it has become a lot harder to do so since we get treated so well here. While most attendees have been to previous Dev-Jam events, we always have a few new people, and many of them end up staying off campus in a nearby hotel. There is something about staying in a dorm room that bothers them – perhaps it was a bad experience in college.

So I thought it would be a public service to actually show the rooms we get at Yudof Hall.

Each person at Dev-Jam gets their own room. While these rooms tend to hold at least two students when classes are in session, during the summer they are singles. You get a sink and a little kitchen with a microwave, two burner stove and refrigerator.

Dev-Jam Dorm Kitchen

There is a single bed, desk, an armoire (closet) and a chest of drawers.

Dev-Jam Dorm Bed

You even get to control the temperature in the room. I like mine on the cool side and the air conditioning works quite well.

Each room shares a bathroom with a toilet and a shower with one other person from Dev-Jam. While these rooms might be a little close with two people, they are perfect for one. Plus they are incredibly convenient since the event is held in the downstairs Club Room.

So, if you ever decide to come to Dev-Jam, don’t hesitate to stay on campus.

Linux on the Dell M3800

I am way behind on a number of tech reviews, but I’m hoping to catch up soon. Please bear with me.

Earlier in the year I had a disappointing experience with the new Dell XPS 13 and Linux. It was especially hard because I really loved that hardware – not since my first Powerbook have I felt such an attachment to a laptop. I was happy to learn later that there were kernel-level issues with the hardware that had to be addressed, so it wasn’t just my lack of ability in dealing with Linux.

While that story is not over, I did send it back and decided to check out Dell’s other Ubuntu offering, the powerful M3800.

I dutifully placed an order for the Ubuntu version of the laptop, and since it is much larger than the XPS 13 there were more options. I liked the fact that I could get an SSD as well as a standard HDD, so I chose the 256GB SSD option and a 1TB HDD. I travel a lot and thought it would be cool to carry more media with me while still having a fast primary drive.

The order process was pretty painless. Still not as streamlined as the Apple Store, but not too bad.

Then I waited.

My expected arrival date kept slipping. This went on for several weeks until I got an e-mail that, due to a misconfiguration, my order was canceled.

What?

Considering that the website pretty much walks you through the ordering process and indicates any kind of impossible combination (such as a larger battery and an extra drive, since they can’t both occupy the same space) I was confused and a little torqued off.

After a few days to calm down, I decided to retry the process. It turns out that the “misconfiguration” was due to the extra drive, which was surprising. Order it with Windows? No problem. Check Ubuntu and it fails.

Grrr.

I did some investigation and was led to believe that the M3800 Ubuntu version ships with a vanilla 14.04 install. So I decided to pay the Microsoft tax and order the hardware I wanted, and then to base it and install Ubuntu.

This time the process was much smoother, and the laptop even arrived about a week earlier than they told me it would. It was a pleasant surprise.

The shipping box was a bit dinged up:

Dell M3800 Unboxing - Picture 1

But they did a good job of protecting the actual laptop box:

Dell M3800 Unboxing - Picture 2

There were actually two boxes, one holding the laptop and one holding accessories:

Dell M3800 Unboxing - Picture 3

All in all, it was a decent unboxing experience:

Dell M3800 Unboxing - Picture 4

The accessories included the power brick, a restore USB stick and a USB Ethernet adapter.

Dell M3800 Unboxing - Accesories

I liked having the Ethernet adapter since I’ve found installing Linux on a laptop works best when wired. While a lot of modern distros ship the proprietary wireless drivers needed, many times they aren’t enabled during install.

I got the HiDPI touchscreen option (3840×2160) and so I decided to install Linux Mint on it. I figured that if Ubuntu worked on it, I should be able to get Mint to work, and I prefer Cinnamon to Unity, plus Mint handles HiDPI screens much better than Ubuntu. Ubuntu has a scaling factor but it doesn’t really apply across the board, so you end up seeing things like clipped text under icons, etc., and sometimes the selection boxes can be very small. I believe Mint does what Apple does and just doubles everything (i.e. represents system graphics with four pixels instead of one).

This system is screamingly fast (I got the Quad Core 3.3GHz CPU and 16GB of RAM) and the display is solid, but as someone who uses desktops primarily, I wasn’t used to using such a large laptop (although it was quite thin).

Dell M3800 - Mint Login Screen

Mint worked pretty well, but there was a frustrating issue with the clickpad. Sometimes I was unable to select a piece of text on the first try. On a second (or sometimes third attempt) it worked fine, but I could never get the behavior to go away entirely. I have found hints on the Intertoobz that suggest it is a known issue with Cinnamon, so perhaps it will be addressed in 17.2.

My main issue with the unit, outside of the size, was the battery life. I could sit and watch the battery percentage drop, about one percent a minute. This was in light duty mode, such as writing e-mails and browsing the web. While 100 minutes of battery life isn’t terrible, it is less than half of what I am used to.

I took a guess that part of the problem could be in the weird hybrid video controller setup they use. There is both an NVidia card and an Intel card in the unit. I installed bumblebee and that seemed to help some, but it didn’t make the power issue go away.

[Note: as an aside, many thanks to Arch for having such amazing documentation]

Dell M3800 - Mint desktop

Overall, if I was looking for a laptop to replace my desktops, I would have tried to stick with it longer. But the size coupled with the battery issues made me send it back. I was still in love with the XPS 13 so I decided to just wait until they supported Linux on it.

2015 Dev-Jam: Day Two

I should mention that so far the weather in Minnesota has been outstanding. Highs in the low 80s (mid-20s for those of you in the rest of the world) and low humidity.

Too bad I spend most of my time indoors.

When we did our first Dev-Jam back in 2005, we learned a lot. The main issue was that people have different schedules, so being able to come and go whenever was important. That also applies for things like meals. While we strive to be together as a group for dinner (which often involves catering or pizza), everyone is on their own for breakfast and lunch. Since we want to cover all the expenses for the conference as part of the conference, we usually find some way to give people money to spend on food and sundries.

At UMN they have something called “Gopher Gold” which allows students to use their access card to buy things on campus. This works really well, but the problem is that if the funds are not used by the time the conference is over, they are gone. This usually resulted in a mad dash to the student store on the last day.

This year I got the idea of getting a custom pre-paid debit card. With the artistic talents of Jessica, we came up with Kiwi Kash:

Dev-Jam Kiwi Kash

So far it has worked out pretty well.

Day Two of Dev-Jam, for me, was spent working with a client. We don’t stop support during this week and I needed to get one of our customers up on Meridian. As it is a migration and not an upgrade, it took a little longer than usual, and we had to do some database optimization which took longer than I would have liked.

Everyone else, however, seemed to be having a lot of fun. Jesse did a presentation on some of the graphics work he’s been doing.

Dev-Jam Jesse Presentation

This includes the OpenNMS integration with Grafana as well as a new library written in Javascript to generate RRDtool-like graphs. This will help us get graphing into Compass as well as other things.

In the evening we all went to see the Minnesota Twins lose to the Chicago White Sox. The Twins are now 1-3 on OpenNMS Project night (sigh).

Dev-Jam Twins Sign

But everyone seemed to have a good time. I spent part of the evening trying to explain the game to the Europeans, and the stranger behind me pointed out I was doing it wrong, but still is was a great night to be outside with friends.

2015 Dev-Jam: Day One

Ah, it’s that most wonderful time of the year: Dev Jam. Once again we have gathered at Yudof Hall on the University of Minnesota campus.

Dev-Jam OpenNMS Sign

This year marks the tenth time we’ve gathered together to spend a week hacking on OpenNMS. The first one was held in 2005 at my house, and every year since then (with the exception of 2009) we’ve managed to have another one. I’m being sincere when I say that I look forward to this week almost more than any other.

Plus, I get to wear my “special” Dev-Jam T-shirt:

Kiwis come from T-rex

Our project’s mascot, Ulf, showed up at a Dev-Jam many years ago as a gift from Craig Miskell (who came from New Zealand). That he became our mascot wasn’t intentional, but then again it seems in open source all that is required is to create an environment conducive to great things and great things will happen. This year we have people from the US, Canada, Germany, Italy and the UK, all working to make OpenNMS even more awesome.

I wore that shirt as I kicked off this year’s conference. I also got to announce that Dustin Frisch and Jesse White have been inducted into the Order of the Green Polo. It is important to note that both Dustin and Jesse worked with us in the Google Summer of Code project and now are key members of our team. I also got to formally announce that Jesse is now the Chief Technical Officer of The OpenNMS Group. I then turned the meeting over to Seth Leger (our VP of Engineering) and Jesse as Dev-Jam is more about coding than me running my mouth. My main role is to serve as “Julie” the cruise director.

Dev-Jam gives us, as a community, a chance to work:

and a chance to share:

Dev-Jam Presentation

Here, Umberto talks about his work integrating OpenNMS with Elasticsearch and Kibana (code available on GitHub).

We also get to play. Here, MvR and Jessica are working on modeling Ulf in 3D:

Dev-Jam MvR and Jessica

and DJ and Mike Huot (my co-cruise director) play with a 3D printer:

The first day of Dev-Jam seemed to fly by this year. Now that light rail is available from UMN we can travel more easily about the city. In the evening, some of us went to Mall of America while I and others saw Mad Max: Fury Road (which I highly recommend).

Day Two? Minnesota Twins, baby.

DevJam 2015

On 22nd June the 5th season of the year is going to start … OpenNMS DevJAM! We have one week with ~30 attendees from Europe and the United States at the University of Minnesota in Minneapolis to hack and learn with OpenNMS. The event is an unconference style and we gathered projects people want to investigate. We gathered the projects on the Wiki in DevJam 2015 page. If you are interested hit the opennms-devel list or go to real life IRC chat.

We have for the first time Umberto Nicoletti and Marcel Fuhrmann at the conference. Both are sponsored by the OpenNMS Foundation and the OpenNMS Group, the proposed projects around documentation and integration for ElasticSearch. For my point of view, I would like to make two workshops around our current documentation project and how we can improve the handling of configuration in OpenNMS.

I wish all a great time and happy DevJamming

2015 SELF – Day Three

After a rather active night on Saturday, Day Three of SELF was more sedate. I took some time to take pictures.

As a sponsor we had a room named after us, which was cool:

SELF OpenNMS Classroom

The project booths/tables were set up in the hallway around the meeting rooms. There was a table staffed by Google:

Google at SELF

and I was able to get a “Google Cardboard” kit which I plan to review a bit later. The Ubuntu folks were there as well:

Ubuntu at SELF

and Spot was there representing Red Hat with his 3D printer. Mini-Groot from Guardians of the Galaxy seemed a popular choice.

Spot at SELF

Overall, while this conference wasn’t as heavily attended as, say, SCaLE, the average knowledge of the attendees was much higher and we had some great conversations. The people who stopped by the booth seemed genuinely interested in learning about OpenNMS versus gathering swag, although we managed to give most of the stuff we brought away.

OpenNMS Booth at SELF

Since we were monitoring the show network, we decided to leave when the number of associated devices dropped below 60, which turned out to be about an hour before the show was supposed to end. I always feel bad if I leave early, but we’ve been pretty slammed lately, so being able to get home a couple of hours early was nice, and now I have next year’s show to look forward to as well.

2015 SELF – Day Two

Day Two of SELF was a bit of a whirlwind. While I love going to conferences, “booth duty” can sometimes be a bit tiring, but for some reason the time just seems to fly at this conference.

Speaking of booths, I got to stop by the Rackspace table. I have a soft spot for Rackspace since they were our first major customer at OpenNMS and if it weren’t for them we probably wouldn’t be here.

They have a reputation for hiring top-notch people, and at the show they have a little “break/fix” challenge. You are given ten minutes to complete eight tasks, and like Spinal Tap the score goes to eleven.

I was a little disappointed with my score of seven, but I can always claim I was distracted by a couple of people coming by to say “hi” while I was taking the test. Not that it would have made any real difference, but what is a day without at least one good rationalization.

I asked Jesse to give it a shot and he score a more respectable nine, and I didn’t hear of anyone getting it completely right, but it was fun to do.

Monitoring the SELF Network

Speaking of fun (well, if you are a network management geek) we set up some more data collection on the show network. We added graphs for the number of people connected to each SSID, as well as the max and average association time between devices and APs. It was cool to see a dip around lunch time as a number of people left to get food, and then it came back up as they returned.

I often talk about how important it is to not only be able to collect data about the network but also to understand why the data is what it is, and it was cool to be surrounded by other geeks who liked to look at the output from OpenNMS and to understand it.

SELF Cards Against Humanity

That evening there was a social gathering sponsored by Linode. I was able to hang out until a little after midnight and everyone seemed to be having a good time. There was the obligatory Cards Against Humanity game going on, and it was one of the largest I had seen. Not sure the game play works that well with so many people but those playing seemed to enjoy it.
