Working with Slash Commands in discljord

At the end of 2020, Discord introduced a new feature that is available to bots: Slash Commands.
Slash Commands belong to a new feature category called "Interactions" which finally allows bots to enhance the Discord UI. As such, the way slash commands (and upcoming interactions such as clickable buttons aka. "components") work is quite different from other parts of the API.

What exactly are Slash Commands?

Slash commands are Discord entities that you can create, edit and delete through requests. Registered commands have a name and a description and are accessible in Discord clients by typing /name.
There are two types of commands: guild and global. As the names indicate, commands of the former type are only accessible in one specific guild

cking

Needs:

• unzip (to extract the nupkg archive)
• zenity (to show fancy progress bars)
• curl (to do the actual web request)
• jq (to parse the json returned by github api)
• wrestool (provided by gnome-exe-thumbnailer and/or icoutils, to parse version info of local xiv launcher)
• tr, sed (for parsing the output of wrestool)
• mv, rm (to move files around)

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,

# Today the twitter user @ayubio said he had received the private key for a Brazillian bank's HTTPS certificate:

#  - https://twitter.com/ayubio/status/994277992351391744
# To prove he actualy had the key, another user asked him to sign a message with such key and so he did:
#  - http://pastebin.xyz/p?q=bXllODA

# The commands bellow will check that signature

# Store the message in a file (tweet.txt) in the same way @ayubio did:

Nix seems perfect for developers - until I try to use it...

Want to use Nix for development but you're not sure how? Concerned about the fluidity of nixpkgs channels or not being able to easily install arbitrary package versions?

When I first heard about Nix it seemed like the perfect tool for a developer. When I tried to actually use it for developing and deploying web apps, though, the pieces just didn't seem to add up.

nix-shell and Shebang Lines

A few days ago, version 1.9 of the Nix package manager was released. From the release notes:

nix-shell can now be used as a #!-interpreter. This allows you to write scripts that dynamically fetch their own dependencies.
