- Some updates to pacman as I'm going to trying to use Open Build Service which apparently has support for publishing Arch Linux packages. Pretty nice! - Starting to take more notes for Git as I use it beyond the simple commit and push workflow. I mostly use it to create patches for packaging other applications. - Updates for Drawabox.

The all-time favorite client-side networking tool for basic stuff.
|
|
It is seriously one of the best free and open-source tool out there with the plethora of protocols, leading implementation for various protocols such as HTTP3, and a lot of configurable options to fully control your request.

|
cURL supports creating requests with different protocols.
|
|
Among them are HTTP, Gopher, DICT, and simple file.
|

To see more, you can view the cURL manual page (i.e., ~man curl.1~) and see the protocols section.
