This post is the second in a series looking at the
design and implementation of my Glitch demo and the
m4vgalib code that powers it.
Updated 2015-06-10: clarifications from reader feedback.
For the first technical part in the series, I’d like to start from the very
end: getting the finished pixels out of the microprocessor and off to a display.
Why start from the end? Because it’s where I started in my initial experiments,
and because my decisions here had significant effects on the shape of the rest
of the system.
Hey, look! I made a little graphics demo!
Update from four years later: I’ve switched away from Hakyll. These notes
are here for their historical value only.
I used to manage this site with Jekyll. I’ve now switched to Hakyll.
Here’s my reasoning and some notes on how it went.
While I’ve been blogging about my personal projects off and on, I’ve been
awfully quiet about my day job. Now I can tell you why.
While djb is perhaps best known for writing qmail, he also wrote a web
server, publicfile. Like his other software, publicfile is simple and
robust. I use it to serve this site, among other software.
Characteristically for djb, publicfile is pretty minimal out of the box. Here
are a few patches I applied to the source to make my server faster, more
flexible, and easier to use.
