The Inverter: Episode 52 – Immensely Deft

For this episode, the Bad Voltage team returns to normal with a taped show clocking in at just over an hour. I really enjoyed this one and it made me remember why I started this little column in the first place. Most of the time they bring up stuff for which I have strong opinions, and these posts let me express my thoughts in some depth. Plus, my three readers don’t seem to mind, if they read them at all (grin).

So, if you haven’t listened to it already, please do so now. I’ll wait.

The first segment focuses on the Volkswagen software scandal where, as Jeremy put it, code was added that basically said “if under test, then lie”. I even came up with a joke about this while in Germany. How many VW engineers does it take to change a lightbulb? Forty, unless the emissions inspector is watching, then it is only one.

I had three main thoughts about this topic. The first concerns the US VW CEO Michael Horn, who blamed the whole thing on rogue engineers. Unlike the overall CEO (I found reference to a “North American” CEO, too, how many CEOs does this company have?) Martin Winterkorn who resigned, Horn is obviously taking the coward’s way out and looking to blame anyone but himself. It seems a little fishy – one would think that all the major engineering decisions would be made in Germany, so had Horn testified to that effect instead of trying to shift blame I would have been a little more comfortable with his testimony, but now it seems like he is trying to hide something, which would suggest he knew about the issue. Winterkorn stated “I am stunned that misconduct on such a scale was possible in the Volkswagen Group” which seems to indicate it was too large to just be confined to one or two “rogue” engineers, casting even more doubt on Horn’s account. But since Horn lives in the US of A it is doubtful anything will happened to him, and even if it did he could always find a high paying job in the financial industry. (sigh)

The second thing that bothers me is that this kind of cheating would not be possible if the code for the cars was open source. Heck, the DMCA specifically prohibits “anti-circumvention” which has been interpreted to mean that attempts to reverse engineer proprietary code are illegal, so even attempting to figure out what they are doing could land you in jail. With growing demonstrations of huge security issues in automobile software something needs to be done about it, and of course I’d like to see things become more open. I have been thinking about selling my car, a 2004, but one thing that has kept me from doing it is the thought all of the possible software holes in new vehicles.

Finally, as someone who once owned a 2002 Jetta TDI, part of the diesel ownership experience is the idea that you are helping the environment. I can run biodiesel in it, perhaps from recycled cooking grease, and the overall pollution equation is supposed to be close to that of a hybrid (when you consider the environmental damage used to make the batteries) or an electric car (the majority of electricity in the US is from coal, so add that to the damage caused by mining rare earths). To find that you have been lied to and are actually a huge polluter is quite a blow, and it is the one thing VW won’t be able to easily fix.

One of my team owns a later model TDI and I am very interested to see what happens. My guess is that a software-only fix will simply dumb the power curve down to the point where the car is unusable (and modern diesels can be quite peppy). Think about it: using Jeremy’s “if-then” analogy above, “set test=true” and bam, you pass emissions. Probably makes the car run like crap or they would have done it from the start, but that is an extremely easy software fix. My prediction is that it will take a class-action to get VW to address the problem properly, which will ultimately involve a car “buy back” program.

Anyway, I’m sure the guys will revisit this in the near future and I look forward to hearing more of their thoughts.

The next segment talked about a portable desktop/laptop thing from System 76 called a Serval Workstation. This is a monster device, weighing nearly nine pounds without the charging brick in the 17-inch form factor, that is meant to be a laptop that acts as a high performance desktop.

Several years ago I became tired of lugging even my small laptop around, and so I found a deal on Woot for a decent desktop and bought two of them. I added a couple of nice monitors and now I have one at home and one at the office. With everything I need being accessible from the network, I really didn’t see the need for a laptop (of course, I have one for when I travel).

I thought Aq hit it on the head when he mentioned all of the stuff you have to get for a desktop: keyboard, mouse, camera, speakers, etc., that just comes with a laptop. I especially like the built in UPS – as someone who lives in a rural area they are a must for the frequent power fluctuations. Laptops just come with them. Thus the appeal of this device is to create a portable desktop that is easy to move, trading size and battery life for power.

Also, I really like System 76. I tend to vote with my wallet, and when we needed to replace some aging iMacs I bought a bunch of Sable machines from them and we haven’t been disappointed. They “just work” with Linux, and they are both reasonably priced and pretty sharp looking as well.

The one thing I wish the guys had talked about is the anemic 1080p resolution. I hate the fact that so many laptop manufactures seem content with such a limited pixel density. Sure, 1080p on a 12-inch screen is fine, but on a 17-inch monster? My desktop monitors have a much higher resolution, and my latest laptop, the Dell XPS “sputnik” has even higher density. The HiDPI screen has caused some issues, so that could be one reason that System 76 opted for a lower density, but still it would be nice to have a HiDPI solution that just worked.

My final comment on this is that they are actually wrong when it was stated that the Dell Ubuntu version requires patches that must be installed via a Dell repository. I don’t run the Dell repos on my machine as most of the changes have been ported upstream and there was nothing in the repos I actually needed. Yes, it didn’t work out of the box – it shipped with Ubuntu 14.04 but I am running Ubuntu Gnome 15.04 with a 4.1 experimental kernel to address some of the more irritating bugs, but with 15.10 coming out in a week I am very eager to play with an O/S with the 4.2 kernel delivered as standard.

The third segment was on the idea of a “delayed public license” where code would be initially published under a proprietary license but at some predefined point it would convert to an open source license. While I appreciate the idea behind it, this is not a licensing issue that requires a new license. We really don’t need any more open source licenses. Instead, you could just publish it under a proprietary license with the terms that “on such and such a date” the license would become something else.

The idea is that a lot software has a limited shelf life, and once the immediate revenue opportunities have been exploited, there isn’t much need to keep software closed. Thus a small team of developers could monetize their work yet still add an open source angle to it. This isn’t a new idea, as mentioned in the show id software does this with a lot of its technology. First they opened their Doom engine, and a few years later they opened their Quake engine. Easy peasy.

My suggestion would be to promote this behavior versus coming up with a new license. Also, while I like the thought of putting the code up on something like Github on day one with a proprietary license so that it would be out there when the time came to open source it, I would recommended heavily against this line of action. We have been through a number of cases where people have appropriated OpenNMS code in spite of the license, and the discovery process can be quite expensive if not cost prohibitive. Since this method of starting out proprietary and moving to open source was aimed at small development teams, do yourselves a favor and just hide the code until you are ready to open it. It will work out better in the end.

There were a couple of bits at the end of the show. Jono did a quick “Hack Voltage” segment letting people know that many mobile carriers have the ability to turn e-mails into SMS texts. For example, if you are on AT&T, sending an e-mail to your number “@txt.att.net” will result in an SMS to your phone. We’ve used this a lot in OpenNMS (there is even a field called “pagerEmail” for the address assigned to each user) and it was nice to learn about the addresses for other popular providers. Note that if you have a need to send actual SMS messages (say, if your e-mail server or network is down) you can get an inexpensive device that will let you do it for the price of a SIM card.

They closed the show with a nice long “thank you” to us for hosting the Live Voltage show in Fulda. I was quite touched and I bet the rest of the team were as well, and I look forward to the next “hinted at” live outing of the Fab Four.

The Inverter: Episode 51 – Live Europe 2015

What can I say? Best. Show. Evah.

(grin)

Of course, I might be slightly biased since I helped make this one happen. Every year we have an OpenNMS Users Conference and this year it was held in Fulda, Germany. In an effort to attract more people, I thought it would be cool to get some open source celebrities. That didn’t work out, but I found that most of the guys who do the Bad Voltage podcast would come out for the price of airfare and lodging. The fact that it coincided with Oktoberfest didn’t hurt.

The guys may joke that they just throw the show together, but I’ve gotten to see how the sausage is made and they do put a lot of effort into making an episode – especially a live one. With the help of the wonderful people at the University in Fulda, I think it went really well.

We had Jeremy Garcia, Jono Bacon and Stuart Langridge there in person, but Bryan Lunduke stayed at home due to the recent birth of his second child. Well, that and the fact that he hates me. He was there in spirit, however, via the “Bryan-o-tron” which was a large, red button that when pressed would produce Bryan saying a pithy quote. It worked out well and was pretty funny.

The first segment focused on Cybercrime and ways to stop it. I was in the camp that most “cyber” crime is actually old school crime just using computers. A lot of it still relies on people being stupid, naive and/or greedy.

For an example on how low tech crime still works, we recently had our car burglarized and they stole Andrea’s purse. About a week later we noticed nearly two thousand dollars missing from our account. The thieves had written a check from a stolen account and then used her ID to cash it. Even though we had changed our account number and we never withdraw large sums of cash, the bank went ahead and dispensed the cash (the person had gone through the drive through teller and used her driver’s license as ID). This despite the fact that we had reported the theft, changed our account and the signature on the back of the check wasn’t even close to her’s. Of course, they refunded the money to us (after about a week) but I was still amazed that, in this day and age, with debit cards and PIN numbers and multiple ways to ID a person, this actually worked.

The next segment was taken from the first Bad Voltage Live show at SCaLE and it was called “Wrong in 60 Seconds”. The idea is to give people 60 seconds to rant about something, and then the team would judge who did the best job. We were worried about this bit because Europeans tend to be more reserved than Americans, and even with a little bit of beer in them we weren’t sure what the participation level would be.

And our worst fears were realized. Only Ken Wimer volunteered to rant, and we needed at least two more people. Jessica saved the day by volunteering Antonio Russo (a great choice) and I immediately thought Ian Norton would do a good job, so I threw his name into the hat. They all agreed to do it, and it was a lot of fun. The lighting is kind of poor, so you miss the fact that Antonio actually threw his shoes before starting. Ken ranted in German, Antonio in Italian, and Ian in English.

It came down to a tie, with Jessica casting the deciding vote for Ian. The prize was a really nice tablet.

The last segment features Stuart talking about the biggest danger to open source being the people involved. This may seem a little counter-intuitive: open source is a movement made up of people, so how could they be the biggest danger to it? But he makes some good points, specifically you never hear someone in the Apple user community blasting someone because of their choice of application, but we constantly get factions up in arms about Unity vs. Gnome vs. KDE and Ubuntu vs. Fedora vs. OpenSUSE. Even in the opening parts of the show they joke about the three OpenSUSE guys (who came a long way to be at the show) being the *only* three OpenSUSE users. We laugh but it is somewhat endemic of open source culture and maybe we need to change it. It’s one reason we at OpenNMS strive to be both welcoming and tolerant of new users, as they will be the evangelists of the future.

Toward the end of the bit the Bryan-o-tron took a fearful turn as it was no longer static images and canned quotes, but Bryan himself via a Google Hangout. He unleashes his trademark vitriol and then manages to join the show via a DoubleRobotics telepresence robot.

While this worked flawlessly in rehearsal, we had some connection issues and Bryan’s face was missing from the screen. Here is what it should have looked like:

OUCE Robot

In any case, it was funny, and toward the end when he slowly storms off, the robot locked up in forward mode (I’ve had this happen to me) and slammed into the wall, falling over. No harm was done and it was a pretty funny way to end the segment.

That was pretty much it for the show. Clocking in right at an hour, I think it went well. I’ll be eager to see the next Live Voltage when they plan one.

A Wonderful OUCE

Sorry for the delay in posting this, but the fourth quarter is always our busiest time of the year and I’ve been slammed. Plus, I’m still recovering from a great week at the OpenNMS Users Conference. You did go, correct? (grin)

We are always striving to find ways to bring more people to the conference, so this year I thought it would be cool to invite some open source celebrities, namely the guys from the Bad Voltage podcast. Plus, since this year’s conference was in September, we had the opportunity to make a side trip to Munich’s Oktoberfest.

We arrived in Fulda from Munich on Sunday night. Now in the run up to the conference the BV team would sometimes talk a little smack about Fulda (as in “where the hell is Fulda?”, etc.) but I love this town. It is a wonderful combination of old and new, with cobblestone streets and a beautiful cathedral. You can walk everywhere, and for us the fact that the university (the Hochschule) has great facilities makes it an awesome place to hold the OUCE.

Since we rely on the Hochschule we have to schedule the conference during a time when the students are not on campus. While it is usually held in the Spring, this year it got moved to Autumn. I think the weather is about the same, although we did have a snow storm during one OUCE.

The conference itself is two days long, but we put two days of optional training in front of it. I get to teach an OpenNMS “bootcamp” on Monday that attempts to cover most of the basics in a day. So fresh off of Oktoberfest I had to actually work on Monday.

The class went well, if a bit long. The students were some of the best I’ve ever had, and I don’t think we hit many snags except for the occasional typo. As much as I tried to hurry, it still took us about ten hours to cover the material. OpenNMS is such a huge platform that even the basics take time to go over, and perhaps next year I’ll ask the students to do some work before getting to the classroom.

We had about half of the team together for dinner that night, and I got to have some of the dark German beer I like (in this case, Köstritzer). I called it a night early on, although many of the guys headed to a small bar called “The Eck”, which was apparently a lot of fun.

On the second day of training, Jeff and Jesse discussed some of the more advanced features in OpenNMS. I slept in a bit and then worked with the Bad Voltage team to make sure everything was working for the show on Wednesday. This included making sure Bryan Lunduke could access and use the telepresence robot.

OUCE Robot

Normally when we hold the OUCE in Fulda we have access to a student run establishment called Cafe Chaos. Unfortunately this year it is being remodeled, so we had to make our own set up in Halle 8.

OUCE Room

It was pretty cool. We had a large refrigerator for drinks and they set up some couches in the back corner. Being at the University, the bandwidth was stellar.

On Tuesday night Nethinks sponsored a meal at the Havanna Bar. Most people had arrived by then, so it was nice to get together. Many thanks to Uwe and his team for putting this on.

Wednesday was the first full day of the conference. I kicked things off with a “State of OpenNMS” keynote, with an introduction by Alex Finger, the man who pretty much created the OpenNMS Foundation.

OUCE Alex

I thought the talk went pretty well, and thanks to the A/V team at the University you can see it in all of its glory:

After that I could relax and let the rest of the gang take over. There were plenty of amazing talks, and you can catch them all on Youtube.

Speaking of Youtube, Wednesday night was the Bad Voltage Live show. I plan to review that in a separate post, but it was a lot of fun. We ran a bunch of errands Wednesday afternoon in preparation, which mainly included buying a tablet to use as a prize and beer … lots of beer.

OUCE Beer

On Thursday we had more talks, and then, sadly, the conference had to come to an end. Those of us who were still around helped tear down Halle 8. It looked really empty when we were finished.

OUCE Closing

We then headed off to the Wiesenmühle for one final gathering before going our separate ways.

If you like OpenNMS then you really should make plans to come to the OUCE. Next year will be held at about the same time at the same place, so reserve space on your calendar now.

In the meantime, there are two more conferences left in the year where OpenNMS will be presenting. In a week you’ll find us at All Things Open in Raleigh, NC, USA, and in November Ronny and I will be at the Open Source Monitoring Conference in Nürnberg.

Hope to see you at one or all of these.

GrafanaCon in NYC with Jesse White

Just a quick note to point out that GrafanaCon is next week in NYC.

Grafanacon

It’s a free, one evening conference that promises to be a lot of fun.

OpenNMS’s very own Jesse White will be discussing the amazing API he wrote to put OpenNMS collected data into the Grafana dashboard in a talk called “Tales of a Custom Data Source” at 6:45pm. If Grafana didn’t exist, we’d have to write it, and we probably couldn’t have done as good a job as they did.

If you want to see the future of data visualization, don’t miss this conference. Plus you get to see how we plan to display all of the billions of “Internet of Thingies” data points OpenNMS will be storing in Newts.

The Inverter: Episode 50 – Automated

The latest Bad Voltage show, episode 50, was titled “Automated”. It marked a milestone, fifty episodes is a lot and the gang deserves credit for making it that far, and I was surprised they didn’t talk about it. That’s professionals for ya, just another show.

TL;DR: I didn’t really care for this show that much. Now, to me, Bad Voltage is like sex: when it’s good, it’s really good, and when it’s bad, it’s still pretty good, so please don’t tear into me too roughly for not praising it (see how I got “rough sex” into your brain and into the search engines?). This episode was a little more navel gazing than normal. They revisited the Mycroft Kickstarter (and now on Indiegogo), and then moved on to an interview that I thought was unnecessarily brutal. Many geeks are not the most socially gifted people on the planet and being on a podcast, even one like Bad Voltage, can make them extremely nervous and anxious. Considering that this was supposed to be a friendly interview I found it a little painful. Then there was a home automation “Internet of Things” discussion that I found too high level than I would of liked, and the episode ended with Jono’s review of a standing desk.

The show clocked in at seconds under ninety minutes. There is a large variation in times for these podcasts, and I’m happy listening to the team for as long as they are willing to talk, but the shows I like the most seem to be a little more focused, regardless of the length.

This episode started off with the announcement of the birth of Bryan’s second child, a boy named Solomon. It is the main reason he won’t be joining us in person for next week’s live Bad Voltage show, but congratulations are still in order.

The first segment was a discussion of the Mycroft project, which is attempting to create an open source Siri-like digital assistant. Yes, they discussed this on the last show as well, and while the Kickstarter has ended they have an Indiegogo campaign going on as well. I am eager to see what comes of this, but not willing to fund it at the moment. The last time I funded something, the open source fitness Angel Sensor, they took my money and it’s now a year overdue. Not really complaining (if I were complaining I’d be upset that the first app they plan to release is iOS only) but it kind of burned me on these kinds of things.

Still a cool idea, and it may be possible to eliminate any privacy concerns I might have. I need to help out by offering to read some stuff on Librevox as Aq suggests.

The second segment was an interview with Chris Waid. It turns out that the FCC is unhappy that, with software defined radios, one can increase the power in such a fashion that it violates the broadcast license for the device. For example, you could extend your WiFi range using the same gear through software. They want to stop this, but the concern is that the easiest way to do this would be to lock down the firmware for these devices, which would rule out things like installing alternative firmware on your home router, or perhaps even running free software on computers and laptops, as access to the WiFi and Bluetooth chips could be prevented.

While I’m in the camp that this is more a poorly thought out proposal on the part of the FCC than the FCC trying to be malicious, there is a chance this could be a Bad Thing™ and we should take steps to prevent it. However, in their zeal to get to the meat of this problem the team went a little overboard on poor Chris. Even when a guy in the room with Chris tried to help out, the immediate thought was that Chris was being corrected by one of his own guys (which wasn’t the case). Sure, it would have been funny, but Chris just got more flustered and the message got lost.

Now I’m all for skewering the bad guys, although I prefer it be done nicely as in the style of Jon Stewart, but this wasn’t a bad guy. At worst he is overstating the threat a bit, but compared to some of the jewels the US government has put forth in the past concerning technology, overstating the threat is worse than understating it. They do apologize, somewhat, at the end of the show, but the whole segment made me a little uncomfortable.

There was a short segment by Jeremy, resident home automation geek, about a project to mount a tablet inside a bathroom mirror. Not sure if there is a killer app for such a thing, but I have been in hotels with TVs in the mirror so it has possibilities.

The third segment was a discussion of home automation and “The Internet of Things”. A lot of it involved discussing all of the competing protocols and solutions, to the point where Jeremy needs several different hubs just to talk to everything. At the moment it is more like “The Internet of Silos”.

I was surprised no one mentioned X10. Any one of my three readers remember this? It was a home automation protocol that worked by sending signals over the home electrical wiring. I once had tons of the stuff: light switches, controllers, even a device that you could stick under your analog thermostat to turn on the air conditioning. It worked by turning on a small heating element that would make the thermostat think it was hotter than it was. Plus, no cameras or microphones phoning home with who knows what information to third party servers.

Those were the days.

The last segment was Jono reviewing a standing desk he bought. Standing desks are all the rage now, and he wanted to try one out so he bought one by LIFT. We got a bunch of movable desks from Varidesk at the office, and I quite like them. I do agree with Jono that if you are serious about them you need a floor pad.

While it wasn’t my favorite BV, I did enjoy it. It’s not like I want 90 minutes of my life back ‘n all. They also didn’t mention the morse code message from the previous episode and I’ve been too lazy to find out what was up with that. I like little Easter eggs. Perhaps they should come up with a contest where each week clues are hidden in the podcast, and if you put them together you win a laptop or something else cool.

Remember, the next show will be Live at the OpenNMS Conference in Fulda, Germany. We still have a few seats left, and if the 5€ fee is an issue, please drop me a note. We can work something out, and there will be beer.

Review: Varidesk Standing Desk

Several years ago we did a lot of work in Sweden (Hi, Lasse!), and that is where I first saw some really nice standing desks. The first standing desk I ever saw was when I worked at Northern Telecom and it was for an employee who needed one due to health reasons, but it was fixed in place. The ones they had in Sweden (from IKEA, ‘natch) had a little switch that you could use to raise and lower it as needed, and they had places to mount a PC and run cables so they wouldn’t get snagged when it moved.

When I looked for them for the office, I was shocked by the price. A decent one with options pushed $900 and they could go north of $2000 fully loaded. While I’ve read a lot about the health benefits of standing I just couldn’t afford to get such a desk.

Recently I was on an American Airlines flight, and I just happened to see a small ad for something called a Varidesk in the in-flight magazine (and I’ve never bought something from the back of an in-flight magazine). This was something you put on an existing desk and you could use it to lift a monitor, keyboard, etc. to a standing height. It was manual, but it was considerably less than a dedicated desk.

Now, being the CEO of a profitable company it is required that I have the huge executive desk, so I do. Of course, mine was free from a business that was moving offices and all I had to do was go get it, and then repair all of the broken bits so I could put it back together. My monitor sits in one corner of this monstrosity, and I was happy to see Varidesk made a product that would fit perfectly.

Varidesk Lowered

First off, the sucker’s heavy. It cost a lot to ship due to its weight, but that translates to a lot of stability when raised. The unit I bought had a shelf for the monitor, speakers, etc., with a lower shelf for the keyboard.

In the upper shelf you will notice two holes. You place your hands through them to release levers which will allow you to raise the desk. It does take strength to get it started, but then it is balanced so that it becomes easier.

(Note: the little green light on my PC is my OpenNMS Blink notification)

Varidesk Raised

I love that everything comes up with it: the speakers, the monitor, the keyboard, my Yeti mic, etc. It will also go fairly high – I’m a little over six feet tall and I can get it high enough that I’m comfortable using it. It isn’t perfectly stable, if you are energetically pounding on the keyboard it will move slightly, but it is easy to get use to it. I did have to get some USB cable extenders to make sure things like my camera didn’t go flying off when I raised the desk, but outside of that it pretty much worked out of the box.

And, yes, when standing I like to crank the tunes and dance. You do not want to see me dance.

The Varidesk is well built and I did find myself using it, so some of the other guys in the office were interested. They don’t have fancy executive desks, so I got a slightly cheaper model that fit theirs better.

Varidesk Developers

We bought three more and everyone seems to enjoy them, although we probably don’t use them as much as we should. Because they are stylish and convertible, even in the down position they look good.

I found that after about an hour of standing my legs started to hurt. Our office, like many, is pretty much industrial carpet over concrete. There is little padding, so I bought a pad on Amazon that works well for me and I can dance longer.

It’s also cool to elevate the laptop for our daily scrum call:

Varidesk During Scrum

So, if you are thinking about getting a standing desk but already own a desk, consider the Varidesk. While it isn’t the cheapest thing out there, it is well made and will give you experience to see if you even like working standing up, which would be considerably cheaper than buying a new desk and finding you didn’t like it.

Ad hoc Suspension of Polling Services

As I was reading through my RSS feeds this morning, I saw that a user named “Fredebben” had posted a neat find on the OpenNMS wiki.

I didn’t know this, but it turns out that you can temporarily suspend service polling with an event, and then resume it as needed. This is pretty cool, especially if you need to stop polling for just one service.

I once had a client with a requirement that there be a scheduled outage once a week for all services but ICMP. In their case I had them move ICMP into its own package, and then they could use a Poll Outage to suspend polling on the other services. That is still probably the best way to do it for a lot of services, but it is nice to know this event method works as well.

The Inverter: Episode 49 – The Tapas of All Bananas

I am a fan of the Bad Voltage podcast, but as it is hard for me to listen, pay attention and work at the same time, I tend to listen to it on airplanes. A lot of ideas and comments come to me during an episode, so I’m going to start a new feature on this blog called “The Inverter” where I review and comment on each show.

TL;DR: This episode was well done. It was tight, it flowed nicely and clocks in at slightly over an hour. That is their target time but the average show is closer to 80 minutes. There was a cool little mystery at the front followed by a discussion of the Endless Computer project, which was deemed too expensive to succeed. They talked about the horrible Nest smoke detector, version one, and the much nicer version two. Aq reviews Gliffy, a web-based Visio-like application, and they end with a segment on Microsoft’s changing relationship with open source.

This week I’m on a flight to DC so it is time to pull out my copy of the latest Bad Voltage. After the intro, starting about minute three, you get two minutes of what sounds like Morse code.

Intrigued, I found an app that will decode Morse (this webby one didn’t work for me but the Android app did fine) and read the following message:

NEED TO GET THE WORD OUT STOP
BEST WAY TO CONTACT YOU IS THIS STOP
COLLECT INSOTS STOP
WILL PROVE MYSELF MONDAY 1500 UTC STOP
MY CALL SIGN FOR FUTURE MESSAGES IS COVIN END

Now, I’m not sure what “Insots” or “in Sots” are but I thought it was cool that they put this in the podcast, I probably would have added it after a delay at the end of the recording, as it was a little weird listening to two minutes of beeps (I thought my mp3 download was corrupt) but then only the hardcore listeners would have made it all the way through. Apparently you can find more about this in the t00bz but I’ve been too lazy. Cool addition, though.

The first segment was on the Endless Computer, which states it is building a “computer for the entire world” which brings to mind the One Laptop Per Child (OLPC) project. But there are a lot of differences, the main one being that Endless is a for-profit company (at least I think so – during my exhaustive, nearly 60 second perusal of their website, I didn’t find any verbiage to indicate that this was a charitable foundation versus a commercial enterprise).

As a for-profit company, their gear is not inexpensive, and most of the discussion on the show concerned the price, which is pretty steep for the hardware. There is also the issue that you still need to spend even more money to get it functional (as in buy a keyboard and a mouse). Jono, who was the only one who has actually played with the thing, pointed out that the user experience they have created is pretty nice, but the rest of the gang was still stuck on the price.

There is a $169 version, and a $229 version and they both have a funky look, something like an egg.

Now, I have zero experience with the thing but since that hasn’t stopped me from having an opinion before, here are my thoughts.

First off, I loved the OLPC project. I wonder what would have happened if the OLPC project started now, with the vast improvements in open source operating systems, instead of having to come up with their own O/S that was a little hard to understand.

Endless is not OLPC, and I think that’s the main reason for the price point – they need and want to make money.

If I really wanted to get computing power into the hands of the disenfranchised I would have gone with a tablet. For $229, you can make a decent tablet, which would remove the need to have a TV or keyboard/mouse. You could even add an option to charge it via solar cells. Heck, even the Endless website says “as simple as a tablet” which makes you wonder why they didn’t build one of those (margins, probably). With PC sales in free fall, starting a company to make a new one seems silly – like making a “VCR for the World”.

No, what I think happened is that someone found an investor in the Valley who heard “2 billion potential customers” and started seeing dollar signs. We can be the third world Apple! Simply make a funky design, hire a “Chief Growth Officer” and then … profit!

Another sign of impending doom is that they don’t even own the “endless.com” domain name. According to Paul Graham, it matters.

I’m willing to wager Endless is pretty much DOA, but then I guess I’m just bitter in that this pipe dream got funded and I can’t find decent investors for my company, which actually makes a profit. (sigh)

Moving on, the next segment was on the Nest “Protect” smoke detector. Apparently the first generation ones were crap, but Jeremy invested in the second generation and, so far, likes them. They have all kinds of whiz-bang features, such as two different sensors for various types of fires, and a networking feature so that in, say, a three story house like Jeremy’s, the detector on the third floor can set off all of the others.

I’ve avoided Nest products because I’m a bit of a privacy nut (odd, considering that I share most of my life on-line, I know). I don’t want microphones in my house. I don’t want things “phoning home”. Plus, my old smoke detector works just fine and alerts the nice people who provide my security monitoring when I cook bacon, so I don’t see the need to upgrade.

I did like hearing about the feature where the Nest can serve as a night-light and light up when people walk by it, sort of like the lights in a European hotel hallway. But I think I’d rather engineer that solution on my own then to buy something that is always talking to a third party, no matter how often that third party says I can trust them.

This episode the guys have introduced something called “Hack Voltage” in which one of the hosts will review something cool they’ve discovered. Aq did a short segment on “Gliffy” – a diagramming tool like Visio that you can run in a browser. As a hosted solution, you get some bits for free but then you pay a subscription fee for more features and storage. He seemed to like it, but for me I’d rather struggle with something open source, but if I ever have the need for such a tool I’ll check out the “free” version.

For my own version of Hack Voltage, the coolest new thing I’ve been playing with is Google Translate on my watch. I haven’t had time to make a video, but you set up your source and destination languages, speak into to the watch, and voilà, translation. When you flip the watch over (like you would when showing it to another person) it enlarges and displays just the translated text. I plan to use this a lot when I’m in Germany for the OUCE and Bad Voltage Live.

The final segment was on Microsoft warming to open source, which it once referred to as a “cancer”. The new CEO seems to be very open to working with open source projects as well as integrating with them, although certain things, like requiring Surface tablets to boot in secure mode, seem to harken back to the bad old days.

All I can say is that Microsoft has always treated OpenNMS well, including gifting us with an MSDN subscription so that we can improve OpenNMS support on Windows. Overall, Microsoft is much more friendly toward open source than they have been in the past.

That was it for this episode. Short and focused with a minimum of swearing and a modicum of mystery. Just one more show before they descend on the little town of Fulda, and I’ll probably listen to it on the plane ride over there. Hope you can make it.

OUCE 2015: Fulda? Where is Fulda?

With the OpenNMS Users Conference less than a month away, I hope you have convinced your boss to let you attend. Ronny updated the website recently, the call for papers has closed and the schedule is being finalized.

With that in mind I thought I’d share a little about the town of Fulda (pop. 65,000) where the OUCE is being held.

The reason we are holding the OUCE in Fulda is mainly due to it being the home of the Hochschule Fulda, the University of Applied Sciences. This is where a number of OpenNMS contributors went to school and some of them still work there. The facilities are excellent, as is the bandwidth, and the town itself is pretty cool.

The city started in 744 when Saint Sturm founded a monastery there. For someone from the United States it is mind boggling to visit a place that is nearly a millennium older than most places in my country. Thus modern Fulda is a mix of old and new.

In addition to the university, the OUCE will visit a number of other places. On Tuesday night, Nethinks is hosting a dinner for the attendees at Viva Havanna, a Cuban style restaurant (I learned that in German, the extra “n” actually means the “n” sound is pronounced in a shorter fashion than normal). On Wednesday night we’re having the Bad Voltage team do a show, and afterward we’ll most likely end up at a biergarten called the Wiesenmühle.

It is easy to get to Fulda. If you are coming by air, the closest major airport is Frankfurt (FRA) and you can take a train from there to Fulda Station. The website has more details.

Fulda has some historic significance as well. Nearby is the Fulda Gap, an east-west route often used by invading forces into Europe and it was thought to be a primary route any Soviet invasion of NATO countries would use. Thus there was a strong military presence in the area during the cold war.

My favorite “Fun Fulda Fact” is that the monastery there was responsible for the survival of the book/poem De rerum natura (On the Nature of Things). Written in 100 BC by the Roman poet Lucretius, it was one of the first books to state that the world could be explained by natural phenomena versus gods, and includes such gems as all matter being made up of atoms. As you might imagine, there were those who disliked these ideas and thus all copies of the poem were thought destroyed.

However, in 1417, ­Poggio Bracciolini found one at the Benedictine abbey at Fulda. He made a copy, and thus the book survives to this day. Author Stephen Greenblatt wrote a book called The Swerve about the impact of the poem. From the New York Times article “The Almost-Lost Poem That Changed the World”:

Titus Lucretius Carus’ “De Rerum Natura,” or “On the Nature of Things,” is a 7,400-line poem in Latin hexameters written in the first century B.C. It covers philosophy, physics, optics, cosmology, sociology, psychology, religion and sex; the ideas in it influenced Newton and Darwin, among others.

Cool, huh? Well, I have been to the abbey in Fulda, and you can too, if you come to the OUCE. Hope to see you there.

Send an SMS with OpenNMS

I thought I’d written this post years ago, but apparently I didn’t. Since my friend Salma asked about SMS notifications with OpenNMS I felt it was a good opportunity to document this process.

Of course, OpenNMS can’t send an SMS message without a little help. You’ll need some sort of modem that can actually connect to the network. We use one from the great folks at MultiTech.

Multitech Modem

It’s USB powered, so all you need to do is insert an active SIM card and plug it in. Here is the exact model:

Multitech Modem Back

and you can find more information on their products on their website.

For the SIM card, I just added a phone to my AT&T plan for a few dollars a month.

The next thing you’ll need is software to send the notices. I used smssend, which comes in RHEL/CentOS via the smstools package:

Name        : smstools
Arch        : x86_64
Version     : 3.1.15
Release     : 12.el7
Size        : 748 k
Repo        : installed
From repo   : epel
Summary     : Tools to send and receive short messages through GSM modems or mobile phones
URL         : http://smstools3.kekekasvi.com
License     : GPLv2+
Description : The SMS Server Tools are made to send and receive short messages through
            : GSM modems. It supports easy file interfaces and it can run external
            : programs for automatic actions.

This will install a daemon called smsd that is configured via /etc/smsd.conf. You’ll need to edit that file to set the path to your modem, in my case it’s /dev/ttyUSB0. Then start the daemon (via “service” or “systemctl”, etc.)

At this point you can test if it works by running:

smssend [number] "This is a test message"

Note that the number must include the country code, such as “+19195330160”.

Once you have that working, it is pretty easy to set up in OpenNMS. First, edit notificationCommands.xml and add the “smssend” command:

    <command binary="true">
        <name>sendSMS</name>
        <execute>/usr/bin/smssend</execute>
        <comment>Send an SMS</comment>
        <contact-type>mobilePhone</contact-type>
        <argument streamed="false">
            <switch>-mphone</switch>
        </argument>
        <argument streamed="true">
            <switch>-nm</switch>
        </argument>
    </command>

This configuration includes the full path to the “smssend” command, and I used the mobile phone “-mphone” field as well as the short message “-nm” field, which are the only two parameters required for the command.

At this point you’ll need to restart OpenNMS. It actually isn’t necessary to make this work, but it is needed to make the webUI know that the “sendSMS” command has been added.

The rest of the configuration can be done through the webUI. For every user you want to receive SMS messages, make sure that their mobile number (including country code) is configured on their user account page. Then you can just add “sendSMS” as a notification action on a destination path and it should just work.
