Growing cabbage in Uganda, my home country, is pretty easy. All you need is a piece of land, know when it will rain, and plant your cabbage. The land is fertile with two rainy seasons so you can have a good crop without applying fertilizer or irrigating the land.

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

The Onshore Anchor is critical to the success of any distributed delivery team, as it plays a key part in helping to overcome the artificial construct that is having software development teams split across different cities and time zones. The Onshore Anchor is not an additional role or person for a project team, but rather a specific responsibility that needs to be taken on by a member of a distributed delivery team. It is carried out in a..

In the previous section we went over the login with Google process, in this section we’ll go over the login with Facebook. At this time we’ll skip the “invite friends” option since that is blog post all on its own and we can just add that functionality to the completed application. Facebook has a “get friends” API call that we can use, the downside of that is that it will only return our friends that have already joined the app so w..

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..

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....
