The Cloudflare outage was a good thing

Cloudflare, the CDN provider, suffered a massive outage today. Some of the world's most popular apps and web services were left inaccessible for serveral hours whilst the Cloudflare team scrambled to fix a whole swathe of the internet.

And that might be a good thing.

The proximate cause of the outage was pretty mundane: a bad config file triggered a latent bug in one of Cloudflare's services. The file was too large (details still hazy) and this led to a cascading failure across Cloudflare operations. Probably there is some useful post-morteming about canary releases and staged rollouts.

Crypto miner removal

This manual describes how to remove a trojan I came across on someone else's machine.

The trojan seems to contain a crypto miner, and spreads through infecting USB sticks.

Here are hashes of the trojan's main files:

svctrl64.exe:

md5: b88b2c61844a49fcc54727105ae9abac

Updated Version:

If you want to download an older version ive heard 205.15 works well, i reccomend ApkMirror

Follow the instructions from https://github.com/vendetta-mod/Vendetta
After the client is installed, navigate to Settings > Plugins, then click the +, and finally paste https://vd-plugins.github.io/proxy/maisymoe.github.io/strife/Experiments into the input and click Install
Once the experiments plugin is enabled, reload the app then go to Settings > Experiments > Tabs V2 - redesign opt-out/in for all and select Control Bucket.

How to uninstall guix

Date of creation: 2022-12-27

First of all, if the install script referenced here was used to install guix, ideally the output of that script as well as the script itself should have been saved somewhere. This makes it easier to see which components were installed and where and thus makes it easier for you to uninstall them.

As for me personally, I used the install script to install guix on a debian derivative distribution with systemd. This guide thus focuses on uninstalling guix from a debian derivative distribution but will probably work for your distribution as well with some slight changes.
