stdsimd documentation PR. Turns out, I'm not only a one trick pony and I'm brushing up on my Rust! stdsimd is Rust's foray into providing native SIMD instructions without reaching down to intrinsics. My goal in that project is to lower the gates for understanding by providing useful and beginner friendly documentation on a performance topic that's unusually hard to start people on. If you read the PR, do check out the Rust Godbolt links with the side-by-side assembly instruction. Those took a good couple of days to get up and running, and I'm pretty proud.
Let's talk about failures and how I spent a good afternoon not making Term.jl.
updated the mold jll recipe.
I did an initial code review of Tyler J. Thomas's repo (a monthly sponsor!), [RAPIDS.jl](https://github.com/tylerjtho

	# Thank you, and welcome!

	First and foremost, thank you. You are receiving this email because you are helping me, Miguel Raz Guzmán Macedo, build free and open source software and realize my dream of doing this full time. Every donation is incredibly appreciated, and this has been a surprising month. What follows is a summary of what your donations has helped me achieve this month, but before I get into that...

	# The situation in Ukraine

	So, war is bad and Vladimir Putin has decided to invade Ukraine. This is a time of upheaval and tragedy and violence and it's been overwhelming to say the least. Other people in the [Julia community](https://discourse.julialang.org/t/information-for-julia-community-in-ukraine/77118/7?u=miguelraz) have already put together some resource on how you can donate to relief efforts, so please consider doing so if you haven't already. I unequivocally condemn all wars of aggression and imperial annexation - may the Julia community also emphatically reject those who support those

	julia> function sol(arr)
	# Bail early if too short
	length(arr) < 2 && return 0
	# Idea - normalize to positive ints and use RadixSort
	# then take the maximum of the diff
	mini = minimum(arr)
	# Use ternary operator `?` and broadcasted in-place addition `.+=`
	mini <= 0 ? arr .+= abs(mini) : nothing
	# Use in-place RadixSort to modify `arr`
	sort!(arr, alg = RadixSort)
