A lot of people seem to think that distributed tracing isn't useful, or at least not without extreme effort that isn't worth it for companies smaller than FB.

I got the GNU Modula-2 compiler working on OpenBSD

Let's write a toy UI library
We begin by writing a few helper functions that will invariably prove useful to us later. We will be dealing with a lot of rectangular regions on the screen, so it makes sense to start by defining a rectangle structure and write some code to manipulate it.

Real-time Drone object tracking using Python and OpenCV
After flying this past weekend (together with Gabriel and Leandro) with Gabriel's drone (which is an handmade APM 2.6 based quadcopter) in our town (Porto Alegre, Brasil), I decided to implement a tracking for objects using OpenCV and Python and check how the results would be using simple and fast methods like…

Fizz Buzz in CSS
How many CSS selectors and declarations do we need to produce the Fizz Buzz sequence? Of course we could do this with no CSS at all simply by placing the entire sequence as text in the HTML body.
