By default, EBPF programs will not run on WSL2 due to required kernel modules missing. The following example error is an 
indication of this problem:
  modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/4.19.84-microso
  ft-standard/modules.dep.bin'
  modprobe: FATAL: Module kheaders not found in directory /lib/modules/4.19.84-microsoft-standard
  chdir(/lib/modules/4.19.84-microsoft-standard/build): No such file or directory

To fix this you need to rebuild the WSL2 kernel with the missing kernel modules. The below instructions are for Ubuntu 18.04 WSL2.

1. git clone https://github.com/microsoft/WSL2-Linux-Kernel.git

Installing IPAs on Apple Silicon (M1)

1. Open Apple Configurator 2 and plug in your iPhone or iPad
2. Click Add, login to the App Store and select the application you want to install
3. Open up ~/Library/Group\ Containers/K36BKF7T3D.group.com.apple.configurator/Library/Caches/Assets and wait until the TemporaryItems directory appears
4. Copy the application from the newly created temporary directory, but do note that it will disappear once Apple Configurator is done installing
5. Double click the .ipa on your Apple Silicon (M1) device and install it
6. Fix permissions on the installed application by running sudo xattr -rd com.apple.quarantine /Applications/<your_app>.app (if you skip this step, you're unable to start the application)

Note that it's easier if you already have the application installed, as Apple Configurator will prompt you about overwriting the existing installation, at which point the temporary file (the .ipa) will still exist, until you choose an action in the prompt.

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
