Ampelmännchen

2010-03-15T18:43:58+00:00

Just a quick post between a lovely weekend at the beach and the Open Source Business Conference.

Last year I managed to visit Dresden where I saw for the first time, in person, the ampelmännchen. These are the rather unique street crossing lights that can be found in the former East Germany. It wasn’t the first time I was introduced to them, however. That was at the house of Jonathan Sartin (OGP) in the UK, where his son Eddie had plastic toy versions of them.

In fact, there are a number of shops dedicated to the symbols.

However, I was unable to find ampelmännchen cufflinks. Since I live in a area that has a high density of artisans, I decided to have a pair made.

I think they turned out rather well. They were made by Sandra McEwen in silver and enamel.

This Week in OpenNMS: Move Along, Nothing to See Here

2010-03-15T14:00:47+00:00

It's time for This Week in OpenNMS. In the last (half) week, we did more bug fixing and specifying of new work. But, since it's only been a few work days since the last TWiO, there isn't too much to report. :)

Project Updates

Stable: Current Release is 1.6.10

1.6.10 is the current stable release, tagged March 9th. It adds a few small features and fixes a few bugs. For a full list, see the bugzilla 1.6.10 milestone. This is a non-critical but recommended upgrade for anyone on OpenNMS versions older than 1.6.10.
Unstable: Current Release is 1.7.10

1.7.10 is the current unstable release, tagged March 9th. Since 1.7.9, there have been quite a few bug fixes, and a few new features, including allowing the remote monitor to phone home over HTTP, pushing data collection to a TCP daemon, and integration of the Jasper reporting engine. A full list of changes is in the release notes.
Unstable: Bugzilla Triaging

Seth spent more time going through Bugzilla, fixing some of the low-hanging fruit and getting everything categorized in preparation for 1.8. If you know of a particular bug that is vexing you, please vote for it in bugzilla. We can't close everything for 1.8.0, but we can try to get to as many of the top hits as possible before release.
Unstable: Reporting

Jason and Jonathan are both working on a bit more cleanup in the reporting engine, and we're also starting to see some nice sample reports trickling in.
Unstable: New Remote Monitoring UI

Matt and I spent some time fleshing out the specification for the new GWT-based Remote Monitoring UI. I think this is the first time ever I've been excited about maps. ;)

Upcoming Events

March 17th-18th, 2010: Tarus will be at the Computerworld Open Source Business Conference. Drop him a note if you want to chat. Tarus loves to discuss rare 16th-century vases, I swear! So, do your homework! ;)
April 10th, 2010: Jeff Gehlbach will be speaking at the Texas Linux Fest on using OpenNMS in enterprise environments.
April 19th-23rd, 2010: OpenNMS training will be available through The OpenNMS Group at the OpenNMS training facility in Pittsboro, NC.
May 6th-7th, 2010: The second annual OpenNMS Users Conference will be held in Frankfurt, Germany, thanks again to Nethinks. The call for papers ends January 31st, if you are interested in presenting.
May 18th-20th, 2010: David Hustace, Craig Gallen, and Tarus Balog will be attending the TeleManagement Forum's ManagementWorld conference in Nice, France. If you use or are interested in OpenNMS and will be at the conference, please let them know, they'd love to meet.
June 12th-13th, 2010: The OpenNMS Group is a platinum sponsor of the Southeastern Linuxfest to be held in South Carolina. Since it's close, we expect a lot of the OpenNMS crew will be able to make it.

If you have anything to add to the events list, please let me know.

Until Next Week...

As always, if there's anything you'd like me to talk about in a future TWiO, or you just have a comment, criticism, or GWT tutorials you'd like to share, don't hesitiate to say hi.

We just came back from our local farm shop and I was surprised to see a picture of mine hanging on the wall in it:

I did not see the dog anymore around and he was old, the picture is actually form 2008. So might be he is no more and they put up the picture as a memorial.

Ok, ich hatte geschlafen.

Open for Business

2010-03-12T15:50:50+00:00

A few weeks ago I wrote about the new “opensource.com” website. I’m pretty happy with it and since they were looking for people to get involved I offered to write a column on running an open source business based on my experiences with OpenNMS.

I’m calling it “Open for Business”.

The first column was published today, and I love the logo they created for it. Please let me know what you think, but better yet, sign up on their site and post comments there.

New Stable and Unstable Releases

2010-03-11T22:30:50+00:00

The gang has moved up to monthly releases, so hot on the heels of the February updates are two new releases this week.

The latest stable release is OpenNMS 1.6.10. This release contains bug fixes and while not critical, all users of 1.6.x before 1.6.10 should consider upgrading.

The latest development release is OpenNMS 1.7.10. This has a rather large number of bug fixes and features, including the ability to use the remote monitors over HTTP, push collected data out over a TCP port, and the much talked about JasperReports integration.

Ben has included more information in This Week in OpenNMS.

This Week in OpenNMS: Catching Up

2010-03-10T15:46:48+00:00

It's time for This ~~Week~~Month in OpenNMS. In the last month or so, we did a lot of bug fixes as well as finishing up a whole raft of new features.

Project Updates

Stable: Current Release is 1.6.10

1.6.10 is the current stable release, tagged March 9th. It adds a few small features and fixes a few bugs. For a full list, see the bugzilla 1.6.10 milestone. This is a non-critical but recommended upgrade for anyone on OpenNMS versions older than 1.6.10.
Unstable: Current Release is 1.7.10

1.7.10 is the current unstable release, tagged March 9th. Since 1.7.9, there have been quite a few bug fixes, and a few new features, including allowing the remote monitor to phone home over HTTP, pushing data collection to a TCP daemon, and integration of the Jasper reporting engine. A full list of changes is in the release notes.
Unstable: Reporting

Jason Aras and Jonathan Sartin both completed their reporting work, and it has all been integrated into the OpenNMS 1.7 series. The new reporting engine is available in 1.7.10.
Unstable: MultiOutputRrdStrategy

Seth's RRD strategy, which will let you write performance data to RRDs as well as a TCP socket, was released in the 1.7.10 release.
Unstable: Remote Poller Updates

The remote poller HTTP RMI work has been completed, and integrated into the 1.7 series.
Unstable: Hyperic Alarm State Integration

Seth and Jason finished up work on support for pushing Hyperic alarm state to OpenNMS, expanding upon the existing Hyperic HQ integration.
Unstable: Move to Spring 3.0

We've updated our plumbing to use Spring 3.0.
Unstable: MMTM Updates

The SMS monitor infrastructure has gone through a lot of bugfixing in the past weeks, and is solidifying nicely.
Unstable: Eclipse Updates

A number of changes have been made to make it easier to use m2eclipse with Eclipse. Updated instructions on doing OpenNMS development in eclipse are on the wiki.
Unstable: Bug Triaging

Seth has spent a bunch of time triaging (and fixing) bugs in preparation for 1.8. Yes, seriously, we are actually in the home stretch of preparing for 1.8. It would be foolish to give a date, but it will be soon. :)
Unstable: Build System Cleanups

We did a bunch of rearranging the build system to speed things up (get rid of extraneous repositories, etc.) It trims build time down by a noticeable amount.
Unstable: Thresholding Without Storing

Alejandro implemented a long-desired feature, thresholding on collected data without needing to persist it.
Unstable: New Remote Monitoring UI

I've been working on a new remote monitoring UI. The current UI we have for displaying remote monitor status has a rather odd algorithm for determining status, and it is a time-consuming one which does not scale to many monitors, as well.

I am instead writing an entirely new UI in GWT which will include a Google Maps integration. You will be able to geotag monitoring locations and use the map to "drill down" into specific areas to view location status by region.

Upcoming Events

Difference between raw and reworked images (Schiffenensee)

2010-03-10T08:50:11+00:00

Fribourg – genevainformation::pictures.

That’s the image as it comes out of the camera when shooting RAW. The camera has done nothing at all to it, so I pass it into Lightroom, twist the colours, sharpen, push the blue a bit:

I think it’s impressive to see the difference. On the other hand the first image is very dusty, a better picture would have had better results.

Upcoming OpenNMS Events

2010-03-09T20:01:32+00:00

Lots of events going on in OpenNMS-land. I thought I’d list a few here:

Early bird registration for the OpenNMS Users Conference to be held in Frankfurt, Germany on May 6th and 7th ends tomorrow. This is the place to be to hear all about OpenNMS, and early registration can save attendees €60.
Next week I’ll be at the Computerworld Open Source Business Conference in San Francisco. Drop me a note if you are going and want to meet up.
On April 10th, Jeff Gehlbach will be speaking at the Texas Linux Fest 2010 on using OpenNMS in enterprise environments. If you have seen any of his OpenNMS and Asterisk presentations in the past, you know how good they are and won’t want to miss this one.
We once again have training scheduled in metropolitan Pittsboro, NC, USA for the week of the 19th of April. These classes are both a lot of fun and the best way to get started with OpenNMS.
David Hustace, Craig Gallen and myself will be attending the TeleManagement Forum’s ManagementWorld conference in Nice, France, on 18-20 May. Again, if you use or are interested in OpenNMS and you’ll be at the conference, please let us know. We’d love to meet you.
And finally, The OpenNMS Group is a platinum sponsor of the Southeastern Linuxfest to be held in South Carolina the weekend of June 12th. Since this is close expect a lot of the OpenNMS crew to be there, and I’ve submitted a couple of talks but haven’t heard back if they have been accepted.

Of course, I’m able to talk, in depth and at length, about OpenNMS pretty much anywhere and anytime (grin). Hope to meet you in person soon.

OpenNMS in Botswana

2010-03-09T18:13:37+00:00

Just a quick post that pictures from Craig Gallen’s trip to Botswana are now available. He told me he had a great time, and perhaps I can visit one day.

Linux Link Tech Show Available for Download

2010-03-04T15:37:32+00:00

Last night I had a lot of fun chatting with the Linux Link Tech Show guys. It is episode #343 and it is available for download.

I love any forum where I can run my mouth for an hour and a half talking about OpenNMS and open source software, and I can’t wait to meet these guys in person at SELF (where we are a diamond sponsor).

Note that it is subtitled “linux talk. unfiltered” and I do use the occasional profanity. The spirit took me toward the end and I did drop one “f-bomb” so if you are sensitive to such things you should probably avoid this podcast.

The bad thing about outsourcing is..

2010-03-04T11:22:42+00:00

..that you pay experts to install a server which leaves a server without any swap space. I’m flabbergasted.

The good thing about outsourcing..

2010-03-04T06:33:06+00:00

..is that it’s not me who has to teach a system administrator that “rebooting the server” is not really a way to fix an issue.

The Tail of the Dragon

2010-03-02T19:59:41+00:00

One of my favorite business books is Geoffrey Moore’s Crossing the Chasm. Perhaps it is time to order the follow up book, Inside the Tornado.

Lately, working at OpenNMS has been like holding on to the tail of a dragon. Moore uses the tornado analogy, but I think I understand now what he means. Since last fall we’ve added five people, and each time we add more resources, we end up with more business and more work. It’s crazy. It’s fun.

It’s a little scary.

But what really excites me is that we are finally getting some traction in positioning OpenNMS as a replacement for tools such as OpenView and Tivoli. Our guy in the UK, Dr. Craig Gallen, gave a presentation today in Dubai on the work we’ve done with the TeleManagement Forum to bring open source development and ideals to the world’s largest telecommunication companies and vendors, so it was appropriate that today we also found out that we have been nominated for the TMForum Excellence Awards in the Leadership category.

The award will go to “the member company demonstrating leadership, dedication and commitment to the Forum’s industry collaboration activities, and overall progress in the industry” and while I hope we win, just being nominated is a win for open source.

If any of my three readers will be in Nice at the TMForum conference this May, be sure to let me know.

New Order of the Green Polo Members

2010-03-02T19:10:04+00:00

OpenNMS has survived and grown mainly through the support of its community. The core of that community is represented by an organization called “The Order of the Green Polo” (OGP) and it is the governing body of the OpenNMS project.

Membership must be earned, and current members are responsible for voting in new members. In fact, there are a number of OpenNMS Group employees who are not members of the OGP – while I tend to hire out of that group it is not something I always do, and membership must be earned regardless of where you work.

It is with great pleasure that I am able to announce today two new members of the OGP. They both hail from Germany, and they, along with Alex Finger (already a member) are responsible for the upcoming OpenNMS book.

I am constantly humbled by what our community is able to accomplish. We had been talking about an OpenNMS book for years, but it took three guys in Germany to actually make it a reality (well, at least real enough to pre-order).

Klaus Thielking-Riechert has been involved with OpenNMS since the spring of 2008 and is a regular contributor to the discussion lists. He and his wife are also fine hosts and have great taste in beer.

Ronny Trommer works for our partner in Germany, Nethinks, and while also involved in the book he has done a lot of work on the code as well. He gave us the idea for integrating with JasperReports. Here is a “morning” outage report he created (click for a larger image):

We have now formally integrated it into OpenNMS and it will be included in the next release, along with a large number of “canned” reports.

In an environment where the role of community in open source is being questioned, I am both excited and humbled to see ours doing so well. Come meet us at the OpenNMS Users Conference (early-bird registration ending soon).

The Open Core Functionality Ceiling

2010-03-02T13:11:37+00:00

Jack Hughes has a great post on The Tech Teapot today. He has been examining the effects of an “open core” licensing model on open source communities, and he hypothesized a “functionality ceiling” in such projects as the feature needs of the pay or commercial version outweigh those of the free or community edition.

Using Ohloh he was able to examine graphs of the code for two well-known open core projects. Both of them show a large plateau, seeming to demonstrate his point.

So I decided to look at the OpenNMS graph. It’s considerably different.

This is pretty cool. You can see a bump when I took over the project in 2002, but due to my limited Java skills it doesn’t grow much until 2004 when Matt Brozowski joined the project. After that the growth is pretty phenomenal. We do have a slight plateau as we are preparing for our next stable release, but nothing like the 18+ month long ones for the other projects, and the size of our code base is much, much larger.

Great idea, Jack.

sportivo.

Corrado e’ stato un giocatore di Rugby molto forte ma soprattutto intelligente.

There’s a first time for everything: Calling the SDIS

2010-03-01T08:56:59+00:00

SDIS is the abbreviation (french is full of abbreviations..) for the “Service Départemental d’incendie et de secours”, the emergency services.

When we came into Cruseilles this morning, there was a scooter crashed on the right side of the road, a boy sitting on the roadside and an adult consoling him – we stopped and we were the first on site. The adult wanted to take a left turn with his car (a small bus) and the boy came up with his scooter – the black ice let him slip, the scooter crashed in the bus and the driver fell on the ground.

He got hurt, but not a lot, mostly scratches on the hands and the ego.

First time to call the emergency services in France then for me – as opposed to my experiences in germany, I had an immediate response and a couple of minutes later the ambulance rushed in.

I hope the week continues in a less dramatic fashion.

Earthquake in Chile

2010-02-28T16:26:37+00:00

One of the major things I love about OpenNMS is its worldwide scope. Last fall we had two students, Javier and Cristian, attend our training course in Pittsboro. They work for Telmex in Chile, and the office is just outside of Santiago.

When I heard about the magnitude 8.8 quake, my first thought was to hope that they were okay. I did get an e-mail from them and they are fine, although Cristian writes “I am hoping the earth stops moving … it is a worrying feeling all day long to feel the floor moving and not knowing when it will come.”

Our best thoughts go out to everyone affected by this earthquake, as well as our hopes for a speedy recovery.

Country side.

Open Source and Building Networks

2010-02-27T06:16:51+00:00

Geoff Davis, a friend of mine from high school who now works at Google, wrote a post about how open source software projects can be used to build up a social network.

I sometimes get jealous of college kids today. When I was in school, computer networking was pretty much limited to BBSs and 2400 baud modems (although the college did have Internet access). I wonder what would have happened to me if open source had be prevalent in those days. All the time I spent drinking beer could have been turned into something more productive. (grin)

As Geoff points out, not only does working on open source projects give you something to put on your resumé, it allows you to make the connections to get that job in the first place.

David

2010-02-26T20:43:50+00:00

David e’ l’ultimo del gruppo di OpenNMS con il quale ho lavorato.

Sono ormai due anni che ci frequentiamo. Che dire…….mi sono trovato molto bene.

Come tutti gli altri lavora molto e non lo fa molto pesare. E’ un buon compagno.

Forse io lo sono un po’ meno in questo periodo perche’ sono molto stanco.

Avrei bisogno di una vacanza.

The Linux Link Tech Show

2010-02-26T19:57:41+00:00

Okay, I’m scared. I was recently invited to participate on The Linux Link Tech Show (check it out on Wednesday, 3 March). I said, sure, but that was before I actually listened to an episode. It’s pretty wide open.

At least I should be able to deal with the format, since each show is over 2+ hours long. I once applied to participate in a 5 minute lightening talk and the guys at the office just laughed, saying that it takes me more than 5 minutes to say my name.

Also, there doesn’t seem to be many limitations on language. I got bleeped on FLOSS for a rather minor vulgarity, so it will be interesting to see if I can keep it clean.

Anyway, if you have a couple of hours to kill next Wednesday, check it out.

OpenNMS in Africa

2010-02-24T18:50:25+00:00

For over three years now, OpenNMS has been heavily involved in bringing open source development techniques to the world’s largest telecommunications providers through the TeleManagement Forum (TMForum).

Dr. Craig Gallen (OGP) is the leader of the TMForum Interface Program (TIP) and he is making a number of presentations about our work with TIP. The first one is being held at the Management World Africa conference tomorrow (25 February).

For many years carriers have be asking for a greater number of open interfaces so that the various management products they need can more easily interact. Needless to say, getting proprietary software companies to share their work has been difficult, but the hope is that by using open source techniques along with permissive licensing we can both increase the number of open interfaces as well as speed their development.

Craig will also be at the Management World Middle East conference, and both of us will be at the main Management World conference in Nice, France in May. If you are going to be at any of these, please stop by and introduce yourself, and we can explain in more depth what we are trying to accomplish.

Race Update: BMWCCA Road Atlanta

2010-02-23T21:38:32+00:00

Jason has posted the results of the OpenNMS Spec E30 BMW from this weekend’s race at BMWCCA Road Atlanta.

He managed a second place finish on Sunday. Go, speed racer, go.

The next two events are driving schools, but they should be followed by our first first place finish. Right Jason? (grin)

SCaLE 8x

2010-02-22T23:08:12+00:00

I have safely made it back home from SCaLE 8x. Once again it was a great show. Unfortunately, I didn’t get to see many talks since I was manning the OpenNMS booth, but the feedback I hear was that most of them were excellent. I really hate the fact that I missed seeing Brian Aker, although he posted some interesting comments on his blog about the show.

My Sunday keynote seemed to be well received. I was a little nervous – not because I was speaking in front of a large crowd, but because I like the show so much I didn’t want to disappoint. If you were unable to see it and are curious about my thoughts on starting an open source business, it is available via streaming on-line.

I made some new friends and after the show managed to spend some time with Karen Sandler and Bradley Kuhn. Bradley and I were able to continue our debate on copyright assignment, with me firmly in the camp of dual copyright and him warning that the potential for evil is still too high. I don’t think we changed each others mind any, but like any rational argument I hope that we each can see better into the others reasoning.

I always love the fact that user group and volunteer driven conferences like SCaLE seem to be better than the “professional” conferences I attend. I am looking forward to SELF in June, where we are a diamond sponsor. Jeff went last year and said it was great, but this will be my first time attending.

More importantly, I am getting more and more excited every day about the OpenNMS users conference in May. I couldn’t be happier with the speakers. The first day, with the exception of my talks, is completely made up of users of OpenNMS who can tell their stories of how they use it, why they like it, and how it makes their jobs easier.

The second day features some of the main developers of the project giving in-depth workshops on the internals of OpenNMS. If you ever wanted to get started customizing the software, this is the place to be.

Remember, early-bird registration is available at a discount and we are required to limit the number of attendees due to space constraints, so if you are interested in coming be sure to register early and often.

Hope to see you there, at SCaLE or at SELF. Be sure to stop by and say “hi”.

WTF II

2010-02-22T21:38:44+00:00

Small update: The roofs of several neighbours broke away as well.

While this might not look all too serious, imagine a solid wooden plank fall from 6m on your head. We’re glad nobody was in the way, because what would have hit you after the wood would have been ICE. Not much better.

Intermission: Business nearly finished

So it’s 10:05 here in the UK, and I’m sitting in the kitchen, listening to verity coughing on the baby monitor, drinking beer and watching Bamboo chug through my latest commit. Not very productive use of a Friday night, I think an Amateur Developer SITREP is in order.

At Dev-Jam 2006, David was kind enough to hand me an assignment use case that, at the time, was more flattering than productive. I spent the best part of the week baffled by maven, Spring and the time zone change, and didn’t make much progress. I did make some lasting friends though, went home fitter than I arrived and also found out why urandom gets through so much lotion.

Anyway, the problem has been bugging me ever since. I think I’ve got it nailed now, but it’s been nearly 4 years. I’ve had intermittent goes at it, including an aborted attempt to completely rewrite the report code. At one point, it started to resemble my own small-scale Project Xanadu. In February last year, whilst “resting” between jobs, I changed focus and started work on an API that could eventually allow the existing reports to be replaced using Jasper Reports or BIRT. Some of the work made it into the 1.7.9 release, but I was effectively stalled.

Interestingly, the impetus to finish the work came from others. Ronny and Jay have been working on Jasper Reports integration, which is now up in the main 1.7 branch. Their efforts prompted me to get my act together, and with some help from Ben, Alejandro and others got the branch cleaned up and tracking 1.7.

I’ve got a deadline now, too. I’ve been accepted as a speaker at the OpenNMS User Conference Europe in May, so I’d better get the code merged up into a release before then. Early-Bird registration is still open, and on the plus side, there will be some proper developers and actual users present. There may even be beer.

In the meantime, it would appear that Bamboo has finally decided that the branch passes all our tests. So it’s probably time to say hi to everyone on #opennms before they quit for the weekend.

Expect another update from me sometime in 2011….

WTF?

I was uploading pictures from our meeting today and compiling nginx (I need a SMTP Proxy..) when suddenly..I don’t know. It made the impression as if someone would be ripping out the garage door or so. Big noise in front of the house.
I looked outside the window and saw snow and parts of my roof hanging down. Apparently the snow had decided to go down the roof in one go, and ripped part of the carpentry with it – on the cars.
Thanks god nobody go hurt in the process. But – I have a roof and two cars to fix now :-/

OpenVPN

2010-02-18T07:16:17+00:00

Among the most useful open source projects (besides OpenNMS, obviously, and RT) is OpenVPN. OpenVPN provides Virtual Private Networks (that’s the VPN), alas secures connections between Servers over unsecure networks (that’s the internet, for example).

OpenVPN is simple. You can start with little effort and accomplish a good level of security straight away from the start. And when you become more complicated, OpenVPN has no barriers imposed – it simply does its job (I see a major role for OpenVPN in constructing Internet 2, but that’s another topic). It’s as well simple from an administrators point of view – the configuration
is straightforward (and not a pain in the butt like IPSec), and in the end you have an interface.
Having an interface for the VPN makes things like routing and firewalling very simple – whatever you have learned about routing or firewalling on Unix applies to the VPN as well. Can’t be much easier.

OpenVPN is as well Open Source Software, fully GPL’d, included or available in all major distributions.

A few years ago, James Yonan, the initiator and programmer of OpenVPN founded a company, probably to satisfy his need to eat regularily. Now the interesting question on companies in Open Source is – where’s the business model?

Tarus bashes regularily the “fauxpen” source-approach where you get a free, but cut-down version for no money but need to pay big bucks for “the real” software.

OpenVPN seems to go a different way: The basis is GPL’ed, free, under development. What they did is to develop an Administration Server which facilitates all the things you need to do to manage a population of VPN-Users. The per user fee is at 5 USD per year per concurrent user, which is well below the market price charged by the competitors.

This fee represents easily the added value – in fact, doing the stuff the server does for you manually would require much more time than the equivalent of 5$.

So there’s a product worth paying for, and it’s based on OpenVPN. Nothing prevents anybody, by the way, to develop a similar product and use OpenVPN as the basis.

I have been using OpenVPN in a commercial context before, and it did safe the company a good amount of money – but as opposed to other tools which did the same, we never got to actually pay or contribute to OpenVPN (I still feel bad about that one). The Server would have been of interest to us (we did develop the functionality ourselves in the end, VPNs were deployed
with a few clicks), but we spent more inernal effort on that than the five bucks per user, that’s for sure.

NASA-SE Winter Meltdown at CMP

2010-02-17T18:40:02+00:00

Jason has posted an update for the first race of the OpenNMS Spec E30 BMW.

Notable takeaways:

Personal best lap of 1:54.2, beating the previous time by 1.5 seconds
… glued to Brian’s bumper for the next two laps before executing a spectacular 360 degree spin in the kink … finished tenth but lowered personal best to 1:53.3
made one last pass on the final lap and held Steven off for eighth place

Unfortunately, his camera rig failed to work so there is no video of Sunday. Next week is Road Atlanta for a BMWCCA race.

Kevin Smith – Too Fat to Fly?

2010-02-16T23:58:34+00:00

I saw a news article this weekend concerning the director/actor/writer Kevin Smith. It seems he was bumped from a Southwest Airlines flight from Oakland to Burbank because a Southwest employee determined he was too big to qualify to travel in just one seat.

He apparently used his powerful social networking presence to “scorch the earth” with his complaints.

The first thought that went my mind was, dude, I really like your movies and Chasing Amy is a classic, but as a frequent flyer, if you are too big to fit in a seat you should have to buy two tickets. Otherwise, you end up in part of my seat that I paid to use, small as it is.

But the second thought that went through my head, hot on the heels of the first, was, wait a second, Kevin is a big boy and I’ve never seen him in person, but he’s not that big. I’ve sat next to much larger people.

Perhaps the media is, err, making a bigger deal (forgive the pun) of this than is warranted?

I was catching up on my RSS feeds this morning and noticed that Kevin had posted on his blog (which is rare). In it he tells his side of the story, which is quite at odds with the published accounts, where it turns out he was flying standby and Southwest made the decision that they could not accommodate him. For some reason they used his size as the excuse to bump him from the flight.

What is really making him angry is that now he has to carry around this very public stigma of being “Too Fat to Fly”.

Look, as someone who has been overweight much of my life, I can sympathize. One of the reasons I work so hard is to overcome the stereotype that fat people are lazy. If you haven’t lived through it you can’t understand.

Now this doesn’t mean I’m forgiving of having an extra-large person sitting next to me on a flight. It’s not an issue of discrimination, it’s an issue of my rights. I paid for a certain amount of room and I should get to use all of it. If you need more room than the default, buy more.

However, Kevin met all the criteria for flying in one seat, and telling people otherwise is discrimination.

I’m a frequent flyer, and it is amazing how many frequent flyers have my approximate body shape. Stick three of us in the exit row of an MD-80 and, yes, we’re going to be a little cramped. We all fit into the seats but there isn’t always enough shoulder room. That’s just the way modern coach seats are laid out. Since it helps to have “elite” status from frequent flying to get in the exit row in the first place, you can imagine that this occurrence isn’t all that unusual.

But I think Kevin’s treatment is a symptom of a much greater problem in air travel. Somewhere in the last 20 years we’ve gone from honored guests to criminals.

First, there is the demoralizing security process. You might claim that it is for our own safety, but the fact of the matter is that it is security theatre. The process didn’t stop a man in the UK from trying to bring a liquid bomb on board, but it now requires every one of us to have our shampoo bottles scrutinized. A man flying into Detroit tried to set his undies on fire, and now every one of us has the potential to be photographed basically naked, even though it has been demonstrated that it is still possible for a determined person to get a weapon on a plane even with full body scans.

One of the most sane articles on the subject comes from the Salon “Ask the Pilot” column which states in part:

… over the five-year span between 1985 and 1989 we can count at least six high-profile terrorist attacks against commercial planes or airports. In addition … were the horrific bombings of Pan Am 103 and UTA 772, the bombing of an Air India 747 over the North Atlantic that killed 329 people, and the saga of TWA Flight 847.

We’ve been dealing with issues of air terrorism for years now, but why in the world have we gone so crazy insane about it? There are over 50,000 traffic fatalities in the US every year, but we accept that in exchange for the ability to drive at 70 mph. Instead of theatre there are things that can be done to minimize the risk to air travelers without treating them like baggage.

Second, there is the plane flight itself. Gone are complimentary snacks and in some cases complimentary beverages. The planes are cramped and often dirty, as there is no time between flights to clean them properly.

Finally, financial conditions are such that many planes in the air are rather old. I know pilots and understand from them that even old planes that are well maintained are very safe, but I’ve personally experienced problems with the aging American Airlines fleet of MD-80s which results in delays and cancellations as repair parts have to be brought in (the problem being dutifully caught in the pre-flight check).

This subject is on my mind since tomorrow I fly for the first time in 2010. It will be a little less traumatic for me since my elite status gets me upgraded to first class. Even then, I still was nearly molested by an American Airlines flight attendant and have never received an acknowledgement to the letters I wrote complaining about it.

What’s the use of working toward elite status if you don’t want to fly?

Luckily for me, OpenNMS has grown to the point that I don’t have to be on the road so much. We have others who can do what I used to do, and in fact do it better.

Deep down I still view air travel as something magical. I mean, seriously, tomorrow I get on a plane at 9am and I’m in LA by 3pm, local time. There I get to meet up with Gareth, Ilan and the rest of the SCaLE gang, get to attend one of my favorite conferences of the year, and I hear the keynote on Sunday is just awesome.

I get to sit in a chair in the sky.

It’s even more amazing when I travel to another country. Get on a plane, take a nap, and suddenly I’m elsewhere, with a new language to learn, new friends to make and new things to do.

But my experiences and those of Kevin Smith have me checking out Amtrak train schedules, and it is doubtful I’ll be on Southwest any time soon.

I have enough problems without being “too fat to fly”.

On Plugins

2010-02-16T19:33:45+00:00

This morning we were trying to set up a GoToMeeting so that Jay could demo the new JasperReports integration into OpenNMS (for those of you playing at home it should be merged into trunk this afternoon).

We couldn’t authenticate.

The http://status.gotomeeting.com site displayed the following:

Whenever I have an issue with a network resource, my first reaction is to get OpenNMS to monitor it.

With many monitoring tools, there is a lot of talk about “plugins”. In yesterday’s post about Nagios, one of the reasons it is so popular is that it is really easy to add custom scripts.

But there is a downside. Since it is so easy to add code, it is much harder to insure that the plugins both perform well with respect to scaling and that they are secure.

This is one of the reasons we build in very generic monitors and data collectors into OpenNMS versus having an open plugin architecture (for example, recently Slashdot had an article claiming that “insecure plugins are a serious threat to all browsers“). The idea is that you should be able to do much of what you need simply by configuring, or at the most modifying, an existing monitor, and those monitors are designed to scale.

I remember at one client they were using Nagios and they had a check script that made a number of SNMP queries to determine the status of RAID controllers on Dell servers. I ported the script to OpenNMS using the general purpose monitor, we pointed it at the entire network (previously, they had only used it on a small number of servers) and went to lunch.

When we came back, the system had automatically discovered over 1400 servers and the load was around 20 (on a pretty powerful box). This wouldn’t do, so we rewrote the script by modifying the existing SNMP monitor to duplicate this functionality (these became the PERC and OMSA monitors). After we switched, the load on the system was less than 1. All of those fork-exec calls were killing the system.

Well, back to GoToMeeting. Once their system was back to normal, the status page looked something like this:

I decided that it would be pretty easy to use the Page Sequence Monitor to test for the string “The GoToMeeting service is currently available”. If that string was on the page, I will assume the service is up.

First, I added the service to the capsd-configuration.xml file:

<protocol-plugin protocol="Go2Status"
     class-name="org.opennms.netmgt.capsd.plugins.LoopPlugin"
     scan="off" user-defined="false" />

I used the LoopBack plugin since I had decided to manually add the service to the GoToMeeting node, so I had no need for automatic discovery.

Then I added it to the poller-configuration.xml file:

<service name="Go2Status" interval="300000" user-defined="true" status="on">
    <parameter key="retry" value="1"/>
    <parameter key="timeout" value="5000"/>
    <parameter key="page-sequence">
      <page-sequence>
        <page path="/"
            port="80"
            virtual-host="status.gotomeeting.com"
            successMatch=
                 "(?s).*The GoToMeeting service is currently available.*" />
      </page-sequence>
    </parameter>
</service>

(don’t forget to add the monitor tag at the bottom)

<monitor service="Go2Status"
     class-name="org.opennms.netmgt.poller.monitors.PageSequenceMonitor"/>

And finally, I used the provisioner to add it to the IP address for “status.gotomeeting.com”:

Voila! I now have a monitor that I know is secure and will perform well and I was able to do this strictly through configuration.

By leveraging the existing monitors and collectors in OpenNMS, sometimes augmented by agent technology such as Net-SNMP, it is quite easy to extend OpenNMS without the need to introduce variables that could degrade either security (such as using ssh and shared keys to access remote hosts) or performance (such as running scripts that require a shell).

We’re Number Two!

2010-02-15T16:51:25+00:00

Just wanted to post a quick note that in the recent Linux Questions poll on the best network monitoring application, OpenNMS came in second.

The winner, Nagios, pretty much destroyed the field, but OpenNMS got more than twice as many votes as the third most popular choice. This wasn’t unexpected, since Nagios is much more of a general purpose monitoring solution, especially within the target audience of Linux Questions. OpenNMS is built for scale, and thus appeals to a smaller set of users.

But still, it was nice that people took the time out to vote. When you work on an open source project, especially a large scale open source project, you tend to be so heads down making improvements that you forget how useful it can be “as is”.

It’s always nice to know that the work you do is appreciated, so thanks to all who voted.

Leadership Lessons from Dancing Guy

2010-02-11T22:02:10+00:00

A friend of mine makes music, and her first CD was published by a company I had never heard of called CD Baby. I fell in love with their wonderful ideas concerning customer service. Here is an example taken from an e-mail after I bought the CD:

Your CD has been gently taken from our CD Baby shelves with sterilized contamination-free gloves and placed onto a satin pillow.

A team of 50 employees inspected your CD and polished it to make sure it was in the best possible condition before mailing.

Our packing specialist from Japan lit a candle and a hush fell over the crowd as he put your CD into the finest gold-lined box that money can buy.

We all had a wonderful celebration afterwards and the whole party marched down the street to the post office where the entire town of Portland waved ‘Bon Voyage!’ to your package, on its way to you, in our private CD Baby jet on this day, Sunday, November 19th.

I hope you had a wonderful time shopping at CD Baby. We sure did. Your picture is on our wall as ‘Customer of the Year’. We’re all exhausted but can’t wait for you to come back to CDBABY.COM!!

CD Baby was founded by Derek Sivers, who has some really interesting ideas on community, running a business and social contracts. On his blog today he posted a link to a Youtube video called “Leadership Lessions from Dancing Guy”. It was from a talk he gave yesterday at TED

If you’ve learned a lot about leadership and making a movement, then let’s watch a movement happen, start to finish, in under 3 minutes, and dissect some lessons.

It’s pretty cool and worth a few minutes to check out.

I’ll File It Under “H” … for “Toy”

The only way to get rid of temptation is to yield to it.

- Oscar Wilde

David was telling me about a program he watched on the Marriott hotel chain, where the founder was saying that he spent 100% of his time thinking about the business. That pretty much seems to jive with my experience, as rarely a moment goes by that I’m not thinking about OpenNMS.

I don’t think this is healthy, so I am trying to find some sort of hobby to occupy my mind that doesn’t involve computers. In the summer I raise vegetables but I wanted something for the winter as well.

I have a mental “bucket list” of things I want to do before I die, and I’ve accomplished several of them. I’ve jumped out of an airplane, gone trout fishing in New Zealand, had sushi in Tokyo, etc. but one thing stood out as a good choice for a hobby.

Learn to play the guitar.

In fact, I have always wanted to play a particular brand of guitar. Many years ago (I’m an old guy, remember) there was a short-lived television show called “Key West” with Fisher Stevens (who played the Indian character in the Short Circuit movies and the bad guy in Hackers). In “Key West” he ran a bar, and in one scene the camera pans across the bandstand and I saw the most amazing guitar. I described it to friend of mine who knows such things and they identified it as an Ovation Adamas.

After many years of wanting one, through the power of eBay and a bad economy, I finally own one. It’s a 2000 Millenium CB edition, one of only 75 made, and while my wife doesn’t like it at all, I think it’s beautiful.

It also has the most unusual artwork on the fret board, featuring all nine planets (remember, in 2000 Pluto was still a planet).

I’m carving out an evening each week for lessons, so perhaps at the next users conference we can all get together and play a little music.

OpenNMS Users Conference Registration Now Open

2010-02-09T14:13:58+00:00

Last year, with the help of Nethinks in Germany, we held the first OpenNMS Users Conference. It was a lot of fun and so we’re doing it again this year, and registration is now open.

It will be held 6-7 May at the Le Meridien Parkhotel in Frankfurt.

Building on the success of the last conference, we’ve extended it to span two days instead of one. The first day will consist of presentations, while the second will be made up of workshops.

I am especially excited that most of the presentations are being given by end users of OpenNMS and not people either associated with the OpenNMS Group or the Order of the Green Polo. The workshops, however, feature a long list of well known contributors and should provide for a high level of technical training.

The cost for both days is 499€, but if you register by 10 March you can save 60€.

Space is limited so register early, and I look forward to seeing you there.

What can you do in the aftermath?

2010-02-09T08:15:43+00:00

You can for example help to operate networks: http://www.opennms.com/415 .

Communication networks are critical for operations in deseaster-struck areas, and making sure they run is something which does not really come to your mind straight away if you think of “helping”.

Congratulations Saints

2010-02-09T00:44:01+00:00

Yesterday I, along with a large number of other people, watched the New Orleans Saints win their first Super Bowl.

Last year I watched the game in a hotel room in Milan (when my Steelers won their sixth championship – number 43 we miss you) but this year I was able to hold a little party.

Now, like hot dogs go with baseball, pizza is fast becoming the food of choice for football, and no Super Bowl party would be complete without some Papa John’s.

Of course, my Mom also showed up (that’s her behind the pies – “Hi mom”) and she brought enough food to feed an army. I think everyone left stuffed.

Anyway, Denise Dubie at Network World wrote an article about how Papa John’s uses OpenNMS, and how they delivered 6 million slices of pizza yesterday.

They worked so we didn’t have to (well, except for Mom. Thanks Mom).

Open Source, Social Contracts and Running a Business

2010-02-08T19:58:01+00:00

When I started my first company in 2002, I had a lot of previous employers to provide examples, both positive and negative, of how to run a business. At the time IBM and Hewlett-Packard were leaders in network management, so I could have modeled my business on them.

Instead I modeled it on Ben and Jerry’s ice cream.

Many might think it was a strange choice, but it seems to have worked out well, at least for us.

First, they make a good product. This is of paramount importance in any business.

Second, they limited the amount of money the highest paid people could earn in salary. In their case, the highest paid person could not make more than seven times the lowest paid person.

I am constantly disgusted by executive salaries these days. Being a previous employee of NORTEL, now in bankruptcy, I find it highly ironic that the executives responsible for driving the company into the ground received huge retention bonus to keep them from leaving. In a just world they would have had no where to go, and particularly they would not be financially rewarded for poor performance.

To me a salary should exist to cover the basic necessities of living, but the real compensation should be based on the performance of the company. Let me stress that I want there to be no limits on overall compensation – if the company is doing well I want everyone’s “upside” to be unlimited. But getting a huge salary just for showing up feels wrong, especially if the company is doing poorly.

Steve Jobs, one of the most successful CEOs ever, takes home a salary of just $1.

Back to Ben and Jerry’s. The one other thing they did that I admired was to donate a certain percentage of pre-tax profits to charity.

I like donating to charity, but I find that I am most eager to give to those organizations that are a) small and b) concerned directly with something I care about. Thus each year I give to the EFF, the FSF and the SFLC, plus a number of local charities.

When the earthquake in Haiti happened, we were shocked and saddened like most of the world. I wanted to help, but I wasn’t sure how. Luckily, the opportunity came in a most unexpected way.

Matt and Jeff (along with Alex) were hanging out in the OpenNMS IRC channel (#opennms on freenode.net) when a man named Andris Bjornson joined and started asking questions about OpenNMS. It turns out that he works for an organization called Inveneo that supplies bandwidth in rural and under-served areas in the developing world. Haiti was the perfect example of a place that needed their services, since a lot of the relief effort is run by non-government organizations (NGOs), and they rely on communications in order to maximize the good they can do.

Haiti’s communications infrastructure, such as it was, was destroyed by the earthquake, and Inveneo is using wireless technology to provide a timely replacement. Of course they need some way to manage this infrastructure (as you can imagine, it is in high demand) and they chose OpenNMS.

Andris installing an antenna in Port au Prince (click for more pictures)

Andris has been using OpenNMS for awhile, but he had some questions and there were some issues in managing the radios they were using. The guys in the channel were more than happy to help out, but we wanted to be involved in a more formal way.

We decided to donate a commercial support contract to Inveneo to help them out in Haiti.

It’s pretty cool to be involved, at least in some small way, with getting Haiti back on its feet. It was also cool to have OpenNMS chosen from all possible apps out there to play a role.

You can read more about Inveneo and OpenNMS in this press release, and please consider donating to their efforts.

Open source has a large social component, and I have a theory that being involved in open source software makes one generally more interested in social issues. I want to hear from others about their experiences with social causes tied to open source. Jon “Maddog” Hall is also a fan of Inveneo, and I’d love to have more examples.

UPDATE: Here’s a network diagram of the Inveneo network, and the “How to Deploy” document mentions us by name.

Marketing, now Sales? WTF?

2010-02-05T00:08:07+00:00

The OpenNMS Group has finally moved into double digit employee numbers with the hiring of Brad Miesner as our Vice President of Sales.

I know what you’re thinking – a sales guy? Earlier you post that you hired some folks to do marketing, and now you hire a sales guy?

First, let me point out that I’ve known Brad for over ten years and he started off in a technical role. So he’s not just some guy with no network management knowledge who’s going to pester people to spend money.

Second, interest in OpenNMS has grown to the point that it can be difficult for us to handle, in a timely manner, requests for information about our services. I always focus on our existing customers first, sometimes to the detriment of potential clients, but Brad will insure that our future clients receive the attention they deserve.

But most importantly Brad will have the role of “customer satisfaction manager”. We tend to build close relationships with our clients, and if we should happen to drop the ball, these clients might be a little hesitant to complain directly to the people at OpenNMS with whom they are working. Brad will proactively be in touch with all of our partners to insure that we’re providing the best service we can, and if there are ways we can improve, it is hoped he will hear about them.

Brad comes to us from Network Appliance, voted by Fortune Magazine as the number one “Best Place to Work” in 2009. He was doing really well there, and I think his decision to join our band of open source revolutionaries speaks well for both the company and our future sales prospects.

We are extremely happy to have Brad join our team.

Oh, at one time he worked for a little software company called Zenoss, but I think he’ll quickly adjust to working in open source.
