The program “Facebook Background Task Host” was consuming the entirety of my disk bandwidth on my Windows 8.1 computer. Further, there seemed to be almost nothing written about this program on the internet according to Google. Rebooting the computer didn’t help: after the reboot it was there again. I did not remember downloading anything from Facebook to run on my computer. The solution was to go to the Windows 8 start screen, and find th..

An eagle soared in the blue sky, Unhindered and mightily he rose and fell, With the soiled humanity below his feet, Looked down upon and called him King. A glint of metal broke his reverie, Flustered he called, Who goes there?, Don’t you know this kingdom belongs to me, Speak and say, Who sent thee? My father, the … Continue reading The Missile Man

I’ve been hacking in golang for a while, but I’ll admit that I didn’t get too deep into some of the language nuances until more recently. Since some of them have started to bite me, here’s a little post-mortem of one of the problems I was having. After hacking and testing code all day, I made a seemingly innocuous change, and when running my program, I saw the following error: 2015/07/10 14:34:12 too many open files I didn’t kno..

A/B testing is testing the comparison of two outputs where a single unit has changed. It is commonly used when when trying to increase conversion rates for online websites. Also known as split testing an example would be trying to increase user clicks on a specific button on a website. You may have a theory that red buttons work better then green. You would try out both against real users and see which one performs better.

Some time ago I had to use a new CentOS 7 virtual-machine for some things that aren’t relevant to this post. This machine had to run all the time but also had some problems with a sporadically failing application server. That’s why I decided to monitor the machine, starting with some basic snmp-monitoring. When I added the host to my Icinga monitoring, Icinga failed to do the snmpwalk. After some searching on the host I found out that th....

A big part of truck life is managing the limited amount of space you have available to you. Depending on what sort of vehicle you’re living in, you may have more or less space available to you, but generally, unless you live in a full on tractor trailer, you’re going to have less than 200 ft 2 of space, so you need to be smart about how and where you keep your belongings. As you can see from the picture above, I was able to increase the ov..

How to avoid root scope digests using faster angular events, which mimic the functionality of the existing ng-event directives, but have a feature that allows them to be called in a desired scope, rather than trigger a root scope digest.

When it comes to go to market and marketing there’s lots of pieces in a toolchest that all work together. One that comes a bit later, but if used properly (much like a PR agency ) can be valuable is industry analysts. And while working with a PR agency can quickly start to become clear. How to work with analysts so it is productive on both sides can take a bit longer to figure out, or at least it did for me. Even before you do start workin....

What’s SnailLife”, you say? Well I’m glad you asked! My snail simulation has gone through a couple of names…and even though I was never 100% happy with Gastropoda it was the best I could come up with - a name that was unique and didn’t allow the project to sound too “gamey” (because it’s not a game). All of the cooler names I could come up with weren’t suitable for various reasons (like domain name availability and such).

I’ve [redacted] people’s faces from the photo , both because of the questionable legality of hanging out and drinking in a truck, and for their own privacy. As you may remember from this Q & A session I mentioned that a truckwarming party was in the works. Some planning, a little food, a few drinks, and a week of time were enough to bring the idea to fruition. One of the benefits of living in a truck is that you can have your truck....

Git submodules are actually a very beautiful thing. You might prefer the word powerful or elegant, but that’s not the point. The downside is that they are sometimes misused, so as always, use with care. I’ve used them in projects like puppet-gluster , oh-my-vagrant , and others. If you’re not familiar with them, do a bit of reading and come back later, I’ll wait. I recently did some work packaging Oh-My-Vagrant as RPM’s . My primary g..

There are three browser tabs continously used in my workflow: GMail, Google Calendar, and Google Play Music. I normally have many more tabs open, but these three I access periodically. As the number of open tabs increases, and I fail to cleanup, getting back to my usual three gets a little trickier. So far, I've kept each of these services open in separate windows. But that doesn't always work. Click on any link in your inbox and you're b..

You’ve built your product and you’re now ready for your first major launch. Or you’ve been through a launch or two, but are looking to scale the process as you’re doing more launches and announcements. You really have two options: do it all on your own , or work with a PR agency. One frequent crossroad is that you’re not at the point of a full time PR person, but unsure what a PR agency can offer you; and, further what’s the best way to wo....
