April was definitely my crazy Speaking Month. After an almost one year long self-imposed conference hiatus, I was challenged to deliver four different talks, attend two discussion panels, give one live demo and release one interview. All in a three weeks period span. First I went to PyCon Sette in Florence. A few days later a plane took me to St. Petersburg, Russia, for PiterPy . Finally, the next weekend I was in Rome for the Western E..

In the finance world, it is well defined which investments are assets and which are liabilities. If an investment brings a net positive income over time, it is an asset. Otherwise, it is a liability, something to pay for every month - an outgoing cost. Why would you ever have a liability? It is a bad idea. Every month you are losing money on it. One reason is that there might be something non monetary that you are getting out of it. For....

I’m currently the maintainer of the ownCloud snap. One of the primary target devices for this snap is a Raspberry Pi 2, which is of course armhf. Snapcraft solves a lot of problems when building snaps, but one issue it doesn’t solve is cross-building (i.e. building on one architecture while targeting another). Back in Snappy Ubuntu Core 15.04, every ownCloud release I made for armhf was built on the Raspberry Pi 2.

First of all, disclaimer. I am a math geek. I’ve always enjoyed solving math problems. I even got compare my “math biceps” with other math geeks on the International Math Olympiad. But I wasn’t a wunderkind. I always had better grades than average, but still mediocre for a long time. This is the story of how I improved from mediocre to the national team. In the spring of ninth grade I qualified to go to the national round of the Bulgarian....

I am constantly thinking about the Go language and how things work. Lately I have been thinking how everything in Go is by value. We see this when we pass values to functions, when we iterate over slices and when we perform type assertions. In every case, copies of the values that are stored in these data structures are returned. When I first started learning Go this threw me off, but I have come to appreciate the reasonability this brings ..

For fun (and profit!) I’m trying to see how many checking bonuses I can get. Since it’s super easy to set up direct deposit at work - it’s just through a web portal - I can add, remove, or change the amount going into bank accounts at will. I got to keep track of what accounts I have open. Just to get an idea of what I’ve done, here’s a table:

You start moving trivial bits of code into classes, with the anticipation that you might use it one day. Stop. On naming, semantic clarity trumps brevity. Yup, the verbosity may be worth it.

Truthfully, I’ve been doing a pretty awful job at keeping you guys updated with what I’m actually doing, truckwise. The last time I even showed off the interior in all its shanty glory was almost a year ago. In the intervening interval since my last Home Improvement update, I’ve completed a few fairly large truck projects. By “large”, I don’t mean anything that requires any real technical competence, but certainly larger than fixing the ..

Containers are all the rage right now. At the very core of containers are the same Linux primitives that are also used to create application sandboxes. The most common sandbox you may be familiar with is the Chrome sandbox. You can read in detail about the Chrome sandbox here: chromium.googlesource.com/chromium/src/+/master/docs/linux_sandboxing.md . The relevant aspect for this article is the fact it uses user namespaces and seccomp. Ot....

Introduction Advertising is a competitive market. This probably won’t be the first time you hear something like that, but it’s absolutely true. For every move you make, you have to consider your competitors are getting a step closer to you. Speed and precision are key to the success of the business, but how can we guarantee these with the stress of such a large system? Is that pricing strategy better than what we are running right now?

The primitive integer types supported by CPUs are finite approximations to the infinite set of integers we’re all used to. This approximation breaks down and some computations will give results that don’t match real integers, like 255_u8 + 1 == 0. Often, this mismatch is something the programmer didn’t think about, and thus can easily result in bugs. Rust is a programming language designed to protect against bugs; it does focus on outlawi....

The second reason is to improve performance by closing apps that aren’t needed. My work laptop is a beast, but it still quite noticeabl....

The Atari days When it came to video games growing up, my parents were fairly progressive – although they had no desire to play them, they didn’t see them as anything but fun and somewhat educational.
