We can make this file beautiful and searchable if this error is corrected: It looks like row 6 should actually have 2 columns, instead of 1. in line 5.

Eventcounts

Eventcounts are "lock-free condition variables".

The lock acquisition is removed from the hot path, significantly reducing contention and overhead.

Eventcounts were pioneered by Chris Thomasson and Dmitry Vyukov (from Go multithreading runtime, LLVM thread sanitizer, Relacy Race Detector and Eigen/Tensorflow multithreading runtime).

Backup android app, data included, no root needed, with adb

Backup android app, data included, no root needed, with adb

adb is the Android CLI tool with which you can interact with your android device, from your PC

You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.

Don't hesitate to read comments, there is useful tips, thanks guys for this !
