Experiments in image corruption

Written by Ash on Filed in programming Tags: rust images pc glitchart

I recently saw a post from Daniel Aleksandersen about bitrot in modern image formats, which included a method to quantify how different a corrupted image is from its original. Daniel used random bitflips, but this got me thinking about glitch art - what if we could generate every possible corrupted image and quantitatively state which ones are the best?

Some Interesting Links

One of the things I thought I might try to get myself blogging more (and to force me to actually appreciate things I like) is posting collections of links, things I found interesting or spent time on in the last [time period] - dare I say monthly? dangerous. This seems to be taking root as various YouTube folk start mailing lists, and of course some great newsletters (check out Cryptography Dispatches!) do the same. Without further ado, here are some interesting things I saw during the July-August-ish period for you to peruse.

Making a Ghidra server use a custom SSL certificate

One of the things I’ve noticed is a lack of documentation for the Ghidra server, so I figured I may as well write down how I ended up making it work for our system.

I’m going to follow this up with another post for homebrew devs about what this means for me, fling, wut and so on, but I figured this should stand on its own. So yeah, this is a post about me and devkitPro.

An Average WiiU Bug: SDL Audio

Written by Ash on Filed in brew Tags: sdl programming bugs analysis

Heya! [waving paw hand (blue) emoji] It’s about time for another blog post, since I sure do write them super frequently. I’m tossing up commiting to monthy or, uh, fortmonthy updates like my mate Alex did for a while; mostly for the random small projects I churn through (there’s a broken 3DS sitting on my desk) and to talk about things like this. As you may know, I’ve been cowriting a port of SDL to the wiiu with rw, which is what this post is about! Specifically, one of the many trials of audio.
