Fio: A LEG Ahead

crystal doc with multiple versionsThe Crystal programming language includes a tool for generating API documentation from source code and comments, called via crystal doc. This blog post goes over how crystal doc works with API docs for multiple versions of a project, something I had to figure out while developing CrystalDoc.info, a website I created for hosting Crystal API documentation based around the built-in docs tool.
I developed a tool that determines whether two or more logical statements are equivalent to assist with a digital logic course.
In the interest of wanting to find the best capo to use when transposing songs to play on guitar, I came across a useful webpage called Capo Calculator. While this page is really good at what it does, it is limited in that it’s impossible to use on a mobile device. So I decided to try and create my own version of it. That’s how capo-calc was created.
I have a tendency to collect electronics. Maybe it’s a broken controller to fix. Maybe it’s an old phone or videogame system to hack. Maybe it’s a laptop I only boot up or use every once in a while. Over time, this has accumulated in a sizable collection of everything from videogame systems, to android devices, to audio equipment, to laptop and desktop computers, to microcontrollers and their accessories.
I had an idea after watching both BenEater's and 3Blue1Brown's videos on hamming codes: what if they were baked into the instruction set of a CPU? This would mean that each instruction in a program could be checked and corrected against single bit errors natively, and provide more reliable operation.
I spent a lot of time last summer messing around with VHDL and an Upduino. Nothing too serious, but it was a lot of fun. During one of the many nights I spent researching various things, I came across vpp. It was a preprocessor for VHDL that Takashige Sugie had been working on since 2007, licensed under GPL2.
While tools for generating block diagrams are already included in most HDL development environments, these are typically proprietary (though they may be free as in beer, they're not free as in freedom). Here is how to generate a block diagram from VHDL using netlistsvg (https://github.com/nturley/netlistsvg) and the open source FPGA toolchain on Linux.
It was on a car ride home from school in 5th grade that I asked my Dad what programming language I should learn, due mostly in part to jealousy about a kid my age who had gotten their own app into the iOS app store. I wanted to emulate their success. My Dad recommended Python, and later that week he bought me Beginning Game Development with Python and Pygame.
