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

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

Installing an Android ROM with your Mac via Heimdall and bash

Because every time I want to flash a new ROM, I forgot how I did it the last time.

This is how I re-flashed my unbranded Samsung Galaxy S4 (german black edition) with a stock ROM (because Cyanogenmod crashed my phone all the time). The correct Stock ROM for my Galaxy S4 is: I9505XXUHOJ2_I9505OXAHOJ2_I9505XXUHOJ2

Software you need

adb
heimdall (brew cask install heimdall-suite)
