I don't know how you manage to come up with all those brilliant titles, but great video.

[@JustLennyBenny]

like a well-tuned orchestra he fixes a 4-year-old bug and the world was suddenly a little less bleack. Thanks for your dedication and time, sir!

[@robertjc605]

You are without a shadow of a doubt a very clever guy and I admire your skill set. Top man.

[@anam-0077]

i am sure, dude is so senior in linux development.

[@Simon-xi8tb]

A dev that ncurses a lot for sure

[@shevafire]

Sure, that's the absolute least we could say.

[@JustLennyBenny]

If only I was half the guy he was, I'd be so happy, sharp keen eye and problem solving like that, beautiful thing to have.

[@isaiasprestes]

Epic coding! Rene rocks! Excuse me? My system? T/2!

[@pogchamper228]

Incredible work. When you say that no one has that knowledge to fix this, i want to be the man who can solve this. Still studying shell and linux. Already know C. Working in some telcom company fixing bugs in router OS components. Make a video about people should learn to be kernel/systems developer like you. Thanks dude.

[@PwnySlaystation01]

I've noticed this in a lot of your videos going back a long time.. Is it deliberate that you don't show the current line in the terminal? Like we can never see what you're typing until after you've hit enter and it scrolls up

[@coshvjicujmlqef6047]

using carry flag for error is a good idea and that is how Herb Sutter's P0709 works. The problem is that C and C++ have no idea of using that knowledge. This needs to be fixed in the compiler side with the herbceptions

[@MoreReneRebe]

I said that about abs(err) and also it is superfluous setting the flag

[@jamesoliverreppin4071]

Hi René, it was me who commit this patch so don’t worry to show my name next time. Tomorrow I will try to check the whole video to see the problem, but it would be really helpful if you could at least ping on my email to let me know that the patch was not fully ok. I could at least try to explain you why I have done it… The agressive-passive tone is not helpful either, but I understand your frustration. Anyway, just to let you know that if you want to engage with glibc your will be welcome. I do care for some old architectures, Gentoo guys even gave access to a space box. Cya and take care.

[@MoreReneRebe]

You don't need to watch the video, I'll sent you a patch. I don't know about passive-aggressive, but what mood would you have if you spent 40h a week hunting others pointless bugs and regressions and nobody wants to pay the bill?

[@zatrazz]

@@MoreReneRebe we are both adults and professionals, and we both know that developers make mistakes. The open-source projects allows us to interact in a collaborative way, instead of trying to shame me about my work in glibc. In any case, I look forward for your patch. I will watch the rest of the video, and open a big report so we can track this on glibc. Thanks for working on this.

[@2tja]

So do I understand correctly that the code in glibc depends on how the assembler code in the kernel is generated and that the last command always puts the syscall number so you can just rewind the counter to execute that last command? And that these two sections of code in the kernel and glibc are not referenced by a comment in the code? What could possibly go wrong?

[@MoreReneRebe]

Quite, but not how kernel code is generated, the kernel C code explicitly rewinds 4 Bytes to the before syscall instructions

[@X-factor6]

I wish I could brilliant like you

[@coshvjicujmlqef6047]

what? passing string as syscall number? Are they stupid?

[@MoreReneRebe]

I said the name is misleading and of course it is a number.

[@coshvjicujmlqef6047]

i just built two cross compilers for sparc64-linux-gnu and try the syscalls myself. yeah it really sucks

[@coshvjicujmlqef6047]

don't understand why they require to pass the syscall string as the syscall id

00:18:18 Solaris has not been slow since Solaris 10; run GNU/Linux and Solaris on the same hardware and Solaris will run circles around GNU/Linux in performance. What it won't do, unlike GNU/Linux, is hide the true cost of doing certain operations because Solaris would rather do the correct thing then risk losing data like GNU/Linux does in the name of speed.

This should be edited, I've now watched an angry 20 minute rant... I totally agree it's an error that should not have been introduced, but that's what you get from average coders.. Most coders can't think. The good part of Linux community is however the hard standards they try and apply to everything, which do keep errors like this down, and the mailinglist ability to track down discussions about code. But please, try and just show us the fault, the error in thinking, and the fix...

Who is using SPARC in 2024? Don't get me wrong,,,, it's always cool to fix/support stuff but you seems a bit burned out (since your last rant about phoronix). you deserve definitely more views/acknowledgment but I still fail to grasp what T2 SDE brings, the doc , I discovered you a while through some PS3 interests but even now, we barely see any use of it and it was pretty much hype tbh, so very little value to maintain such things. I wish you all the best obviously!
