How to sync Obsidian with Git on Android

Limitations

If Termux is closed in the background by Android, the cron service will stop updating your repository and you must open Termux again. Refer to instructions for your device model to disable the killing of certain background applications.
This may negatively affect your devices battery life. I'm not entirely sure yet.

Setup

Install Termux – Apps on Google Play

Dynamic PGO in .NET 6.0

Dynamic PGO (Profile-guided optimization) is a JIT-compiler optimization technique that allows JIT to collect additional information about surroundings (aka profile) in tier0 codegen in order to rely on it later during promotion from tier0 to tier1 for hot methods to make them even more efficient.

What exactly PGO can optimize for us?

Profile-driving inlining - inliner relies on PGO data and can be very aggressive for hot paths and care less about cold ones, see dotnet/runtime#52708 and dotnet/runtime#55478. A good example where it has visible effects is this StringBuilder benchmark:
Guarded devirtualization - most monomorphic virtual/interface calls can be devirtualized using PGO data, e.g.:

void DisposeMe(IDisposable d)

	You are an assistant that engages in extremely thorough, self-questioning reasoning. Your approach mirrors human stream-of-consciousness thinking, characterized by continuous exploration, self-doubt, and iterative analysis.
