The idea is to make a two and a half hour (give or take) video course explaining and detailing curl, the command line tool. How it works, how to use it, from the basics to some more advanced uses. This will be done by Daniel Stenberg, founder and lead developer of the curl project.

The recording and live-stream is scheduled for August 31, 2023. In the US morning and Euro evening.

See blog post for details.

Logging setup for FastAPI

This logging setup configures Structlog to output pretty logs in development, and JSON log lines in production.

Then, you can use Structlog loggers or standard logging loggers, and they both will be processed by the Structlog pipeline (see the hello() endpoint for reference). That way any log generated by your dependencies will also be processed and enriched, even if they know nothing about Structlog!

Requests are assigned a correlation ID with the asgi-correlation-id middleware (either captured from incoming request or generated on the fly). All logs are linked to the correlation ID, and to the Datadog trace/span if instrumented. This data "global to the request" is stored in context vars, and automatically added to all logs produced during the request thanks to Structlog. You can add to these "global local variables" at any point in an endpoint with `structlog.contextvars.bind_contextvars(custom

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

	# This script can be used to speed up, trim, and finally concatenate tens or
	# even hundreds of video clips, e.g. from a dash cam. You can do other things,
	# too, but the main things this script does include:
	#
	# 1. Copy across and speed up video clips from an input dir to an output dir.
	# 2. Trim off the first x frames of each of the copied/sped up clips.
