Sign git commits with ssh key

git version must be >= 2.34. Earlier versions don't support gpg.format ssh (signing commits with ssh keys).

If you're printing signature keys in git log by using %GK %GF %GP %GT in git.format.pretty, earlier versions will crash when doing git log with following error:

BUG: gpg-interface.c:284: bad signature
OpenSSH version must be >= 8.8. Earlier versions don't support valid-after,valid-before options.

Creating Timelapse Video From Photos With FFMPEG

Man, there are a lot of outdated and incomplete tutorials about creating timelapse videos from JPG images and photos. Here's a quick start guide to get going in late 2019.

Software

I'm using ffmpeg version 4.2.1 on MacOS. It is free, well supported, and scales up to practically any number of input images or output video length.

There are a dozen paid timelapse software offerings out there, but I suspect they are just polished front-ends to ffmpeg. Small timelapse videos are possible in iMovie 10.1, but adding even a modest number of images bogs it down badly. The easiest approach is to create a rough lightly compressed video with ffmpeg and then edit the result in iMovie.

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

	"""Example combination of FastAPI and Pydantic with aiosql and aiosqlite.

	This module demonstrates the minimum viable integration approach for putting
	together a few components:

	- FastAPI. This provides a very high-performance and type-driving approach to
	building APIs in Python
	- Pydantic. A powerful data validation library.
	- aiosql. Inspired by annosql and originally Clojure's yeSql, a way to programatically,

	# Loads a scene in the background using a seperate thread and a queue.
	# Foreach new scene there will be an instance of ResourceInteractiveLoader
	# that will raise an on_scene_loaded event once the scene has been loaded.
	# Hooking the on_progress event will give you the current progress of any
	# scene that is being processed in realtime. The loader also uses caching
	# to avoid duplicate loading of scenes and it will prevent loading the
	# same scene multiple times concurrently.
