Fangruin raises valid concerns about the SFrame design that creators unfortunately have not acknowledged yet. We reluctantly added this on glibc (it was added near the release) and I wonder if we should wait more.

Not so obvious I must say, but it is still interesting -
Quick skill check. If you want to call yourself a Software Engineer, This code snippet should be obvious to you.

And when I tried to replace glibc qsort with a non allocating, but unstable one, Hyrum’s Law attacked and we had to revert back to mergesort.
I'm currently at this weird place in life where I need to implement my own Quick Sort... This is the moment all my student loans are gonna finally pay off! (jk education is free in my country)

So the @WSJ said Trump’s protectionism and chaos may be pushing America in a direction similar to Brazil. As a Brazilian economist, let me introduce you to Brazilian ideas for making your country rich. They’re incredible ideas. Tremendous. You’ve never seen anything like it👇

And I almost sure that Rich Felker, from mu, would never implement such hack on musl. In fact, newer platform don’t even allow executable stacks at hardware level (Apple Silicon).

In any case, there is a workaround that I plan to backport to 2.41

It was a footgun, designed in a time were ABIs were transitioning to make stack non-excutable. Unfortunately it took 20 years that raise this issue and now it seems binutils will start to warn in more cases where you have a mismatch.

It is interesting that the headline did not get into details why I made this change: https://t.co/chOxuDbJNp In a short: the old behavior was used in a know RCE described in CVE-2023-38408.
Year of Linux desktop will never happen as long as glibc is de-facto standard libc. As far as I know, this regression is wontfix, so many games just won't work anymore. Imagine being a game dev from 5 years ago and making a native Linux version of your game in a good faith,
