For a small project, I needed to be able to control some GPIO with Linux. I
had some experience with the raspberry pi, but I wanted something more open
(hardware wise). I tried the beaglebone black wireless, and was pleased with the
experience. I had a minor issue, is that accessing GPIO with
sysfs was slow
(like 3Khz), and I wanted much faster GPIO.
I toyed a bit with it, and found a lower level solution I explain in this post. It’s in rust because I am learning the language, but it’s low level, so you should be able to do it in C.
While working with
openembeded, I needed specific version of some software
(well, not specific, but not the bleeding edge Arch Linux has).
I didn’t want to use a virtual machine because I wanted shared filesystems to be able to work on the project from Arch and compile it using a stable distribution.
While working on a project that started with an arduino, I ended up having to make my own PCB for size and power consumption.
I moved to the Atmel
atmega328P which is a pico power microcontroller that is
mostly Arduino compatible.
While digging into the documentation, I realized that the Arduino libraries, while being really handy, have a few limiting factors (for example changing pins at the same time) and I started to look on how to code for the avr microcontroller without the Arduino IDE and libraries.
There are many resources online on how to use the avr CPU with minimal wiring, but I will concentrate on the toolchain here.
While the title of this post seems to be a clickbait or an over exaggeration of how a programming language can affect one’s life, it is not wrong. It is not the sole factor, more a piece of a lot of little changes in my life, but it was an important one.
Here is the story of how Elm helped me out of burn out and back to programming with a smile.
When doing web development, it’s not unusual to have to run multiple watchers/server.
For example, you might have an hugo server running next to a webpack watcher.
There is one thing I have noticed with SPA (single page app) login forms. Many
of them keep the password in memory. And when I say in memory, I don’t mean as
freed() memory which may require freezing your PC’s RAM to access,
