Old-school new-school: Optical Tape Archives

I had come up with this "cursed technique" a while back at work, when I needed to transfer a ~1GB file onto a quite old Linux machine that, for "security reasons" had USB mass storage access as well as the UDF kernel drivers disabled (and I was unable to access it over the network). I've adapted the exact command to be more suitable for general use: sudo chgrp -v …

Quick Fix: remove "Mozilla VPN" ads from Firefox Private Browsing window

Switching to Picom (Compton) on the MATE desktop

You may have read some convoluted (and outdated—Compton was abandoned in 2017) tutorials on the matter like MakeTechEasier's, or perused the Arch Wiki article to some despair, but if you are just a layperson who installed the MATE desktop for e.g. Ubuntu 20.04 (Fossa) and wants a slightly faster (i.e. GPU-accelerated) environment, it's somewhat simple to set it up: Open System Tools, Terminal, and run the following commands: sudo …

[DRAFT] Ghetto Guide to CMS

*and by "ghetto", I mean "extremely applied". Basically, it's just interpretive labor on RFC 5652: Cryptographic Message Syntax and RFC 5280: X.509. P.S. CMS is way more technically elegant than PGP. I dare you to read the RFC and compare. Firstly: the "root object" that you'll be shitting nakedly into a binary (or ASCII-armored) file that sits in the filesystem or gets otherwise transferred is a ContentInfo data stream. …
