ViHN: Vim for Hacker News
tl;dr: I made ViHN to read Hacker News without having to move my hands away from the keyboard. It’s freely available on Firefox and Chrome. This is about yet another Hacker News extension. But other people with my obsession for killing the mouse might enjoy it. Most of the content of this article is just […]

Unpacking Elixir: Syntax
Elixir is a language with syntactical roots in Ruby. It also carries the Erlang legacy. Legacy used here as in "a great legacy" and not as in "system you don't like anymore". Ruby is an object-oriented language. Elixir is functional language. The Erlang part has an impact as Elixir was designed to provide strong…

I made a thing to help you make a thing out of a keypad
I do a lot of electronics projects in my spare time, and I tend to try to make reusable parts to save myself effort in the future. Because I have to order ingredients in certain quantities, I often wind up with more than I need for my project.

Gpiozero Flow
Back in 2015, I had the idea for gpiozero — a Python library for Raspberry Pi, making programming GPIO devices simpler by abstraction: instead of thinking about pin channels, voltages, pull-up resistors and rising or falling edges, we think about buttons being pressed and released, sensors...

Reversing for dummies – x86 assembly and C code (Beginner/ADHD friendly)
Before I got into reverse engineering, executables always seemed like black magic to me. I always wondered how stuff worked under the hood, and how binary code is represented inside .exe files, and how hard it is to modify this ‘compiled code’ without access to the original source code.

Reverse Engineer Amazon's Whispersync
I am a big fan of my Kindle. This is the device I’d bring over to a desert island. I am also a fairly frequent user of the highlight feature where you can select a bit of text you like and save it. One thing is bothering me though: the lack of open API on the Kindle to retrieve the data about me. Amazon provides the…

I found an 8 years old bug in Xorg
Let me set the right expectations first. This bug I found is actually not that complicated, it's very straightforward once you see what's going on. But I still think the process it took me to uncover this bug could be interesting. It's also kind of interesting that a simple bug stayed undiscovered for so long. I will…

Notes on “A Philosophy of Software Design”
Jumping on the recent trend, I picked up a copy of A Philosophy of Software Design based on Cindy’s recommendation. It’s a fairly concise read at 160 pages, and I skimmed through it over the last few days, writing up some notes along the way.
