Discover gists

We can get list of changed files between 2 branches/commits by

$ tar --ignore-failed-read -vczf archive.tgz $(git diff-tree -r --no-commit-id --name-only --diff-filter=ACMRT master develop)

Let's see important part:

git diff-tree -r $commit_id:
Take a diff of the given commit to its parent(s) (including all subdirectories, not just the top directory).

How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Perfetto for upstream kernel development

Perfetto is super useful for understanding interactions between the kernel and applications. Outside of Android and ChromeOS, though it's use isn't as common. This doc tries to provide a basic walk through to get started using perfetto for upstream kernel development with classic linux distros, potentially running under qemu.

Install perfetto

Grab the latest linux- tarball: https://github.com/google/perfetto/releases

Often the tests I’m tracing need to run as root, so because of this, I copied the binaries in the tarball to /usr/local/bin/ and chmod +x the binaries to make
