I made a Chrome extension that swaps Times New Roman for Calibri on every site or just .gov. It also had Open Sans and Open Dyslexic, because f**k these people. I’m waiting for Google’s approval for it to install automatically, but you can download it and install it in 90 seconds. Instructions 👇

I've integrated @khorben 's new kernel feature into smolBSD: -I flag will instruct QEMU to load the image in an initrd RAM disk.While at it I made smol images smoler, here's an example of a fast, read only user shell microvm with basic UNIX tools and ssh client, all in 50MB […]

An idea inspired by @agc a couple of months ago: Here's a poor man's port knocking script https://github.com/NetBSDfr/smolBSD/blob/main/contribs/knockd.sh that spawns a smolBSD microvm running only sshd in a read only environment https://github.com/NetBSDfr/smolBSD/tree/main/service/sshd The […]

So ARPANET had a famous "Flag Day" where they switched over to TCP/IP in 1983; it required a simultaneous switchover of all host machines to the new protocol. And I know that "flag day" has since referred to big changes like that in networked systems. I assumed the name referred to some bitwise […]

I occasionally shoot terminal tips back and forth with someone on another network. Their latest is this, which I found really cool. Take the terms of service for services you sign up to. Commit them to a git repo. Set up updates, if you like. Then you can use diff to spot changes as they happen.
