How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

USG ddclient Upgrade Script

How to use this script?

Why, that's simple! Copy this script to your USG, run chmod +x on it and then, as a user with sudo permission, execute it.

Shamelessly borrowed from Brittanic on the Ubiquiti Unifi forums

How to use it?

Simply run the following command (note, if you are at all security concious-don't run it and instead review the script, then copy it to your USG to execute).

A composable pattern for pure state machines with effects (draft v3)

A composable pattern for pure state machines with effects

State machines are everywhere in interactive systems, but they're rarely defined clearly and explicitly. Given some big blob of code including implicit state machines, which transitions are possible and under what conditions? What effects take place on what transitions?

There are existing design patterns for state machines, but all the patterns I've seen complect side effects with the structure of the state machine itself. Instances of these patterns are difficult to test without mocking, and they end up with more dependencies. Worse, the classic patterns compose poorly: hierarchical state machines are typically not straightforward extensions. The functional programming world has solutions, but they don't transpose neatly enough to be broadly usable in mainstream languages.

Here I present a composable pattern for pure state machiness with effects,

# GIT heart FZF
# -------------
is_in_git_repo() {
git rev-parse HEAD > /dev/null 2>&1
}
fzf-down() {
fzf --height 50% --min-height 20 --border --bind ctrl-/:toggle-preview "$@"
}

# Chroot Jail for SSH Access
# Tested on Ubuntu 14.04.2 LTS and Debian GNU/Linux 8 (jessie)
# Reference : http://allanfeid.com/content/creating-chroot-jail-ssh-access

# Had to add/change several things to make it work, including:
# - create lib64 folder
# - copy whoami dependencies that ldd doesn't show to fix 'I have no name!'
# in the customized prompt + create passwd file
