How to use clangd C/C++ LSP in any project

tl;dr: If you want to just know the method, skip to How to section

Clangd is a state-of-the-art C/C++ LSP that can be used in every popular text editors like Neovim, Emacs or VS Code. Even CLion uses clangd under the hood. Unfortunately, clangd requires compile_commands.json to work, and the easiest way to painlessly generate it is to use CMake.

For simple projects you can try to use Bear - it will capture compile commands and generate compile_commands.json. Although I could never make it work in big projects with custom or complicated build systems.

But what if I tell you you can quickly hack your way around that, and generate compile_commands.json for any project, no matter how compilcated? I have used that way at work for years, originaly because I used CLion which supported only CMake projects - but now I use that method succesfully with clangd and Neovim.

Linux (Manjaro [Arch]) on a Thinkpad P14s [T14] Gen2 with Intel

These are my installation-tricks and notes for running Linux on a 2021 Thinkpad P14s Gen2 with 11th gen Intel Core i7-1185G7. It should also be suitable for the Thinkpad T14 Gen2 with Intel as they are technically the same model.

Additionally you may find more AMD specific tips on the gist I've forked. I decided to keep this gist forked as I have used some of the tips they shared and because they inspired me to create my note in the first place.

Sadly there is no entry in the arch-wiki for Intel specific model, but some of the info from AMD one were useful for me. Other useful sources are mentioned in the document in their respective chapters.

Not everything in this doc may be 100% correct as I'm writing this note after having my PC set up and I might have forgotten some of the stuff. I will update it I ever decide to reinstall the OS on my PC.

Linux (Fedora 35) on a Thinkpad P14s [T14] Gen2 AMD

These are my installation-tricks and notes for running Linux on a 2021 Thinkpad P14s Gen2 with AMD Ryzen 7 5850U. It should also be suitable for the Thinkpad T14 Gen2 AMD as they are technically the same modell.
Meanwhile there is also a good test on youtube and an entry in the arch-wiki, which also comments some points mentioned here.

How to recover a dropped stash in Git?

1. Find the stash commits

git log --graph --oneline --decorate ( git fsck --no-reflog | awk '/dangling commit/ {print $3}' )

This will show you all the commits at the tips of your commit graph which are no longer referenced from any branch or tag – every lost commit, including every stash commit you’ve ever created, will be somewhere in that graph.

This is a plain-text version of Bret Victor’s reading list. It was requested by hf on Hacker News.

Highly recommended things!

This is my five-star list. These are my favorite things in all the world.

A few of these works have had an extraordinary effect on my life or way of thinking. They get a sixth star. ★

	###. Not sure if I'll update this gist (though I realise it seems to still have some traffic), but here's a list of

	### - Check out the `nix-darwin` instructions, as they have changed.
	### - There's a home manager gotcha https://github.com/nix-community/home-manager/issues/4026
