Less allocation means better performance. Simple as that. 😎

But how do you actually get there, especially on older runtimes?

@andrewlocknet walks through a practical way to cut byte[] allocations using ReadOnlySpan<T>.

Dive in: https://t.co/UzkRlBXKb3

[Andrew Lock "Sock" @andrewlocknet]

@ICooper @richcampbell If you reference te system.memory package (so you have Span<T>), then yep, it works!

Blogged: New features in Git 2.54: easier rebasing, hooks, and statistics

https://t.co/gNPAOcT5qC

In this post I show some of the new features in Git 2.54 including simple rebases with git history, config-based hooks, and stats with git repo structure

#git

[Andrew Lock "Sock" @andrewlocknet]

@KooKiz The interesting thing though is that the change _was_ completely sound, and only thwarted because the vendored span type wasn't in the System namespace. Switch the namespace, and everything's fixed!

@KooKiz I can't believe somebody competent would do that. Not a chance.
