After tomorrow we'll cover what it takes to get Sched QoS finally done. Having one scheduler that is scalable and portable is not a myth. But to do so we need some help from userspace. And a bunch of other things. Join us in the refereed track at LPC to journey through the various bits and pieces that must be done to get there. Along with a bunch of proposals to tackle some of the trickier areas.

Linux Plumbers Conference 2025

The Linux Plumbers Conference (LPC) is a developer conference for the open source community. The LPC brings together the top developers working on the plumbing of Linux - kernel subsystems, core libraries, windowing systems, etc. - and gives them three days to work together on core design problems. The conference is divided into several working sessions focusing on different plumbing topics, as well as a general paper track.

Tomorrow we'll discuss the need of having performance inheritance enabled for locks by default. As it stands kernel work via Proxy Execution is not enough on its own if userspace does not opt in to take advantage of this facility. Come and join us in this discussion, especially if you work with libc or language interpreter (e.g java or go)

The dream of safe C/C++ code is here.

I have been following this development, and I am in awe at how much has been achieved, now available as a package:

'I witnessed war crimes' in Gaza, former worker at GHF [Gaza Humanitarian Foundation] aid site tells BBC.

"I witnessed the Israeli Defense Forces shooting at the crowds of Palestinians," Anthony Aguilar told the BBC.

He added that in his entire career he has never witnessed such a level of "brutality and use of indiscriminate and unnecessary force against a civilian population, an unarmed, starving population".

Columbia University's OWN faculty were targeting Mahmoud Khalil. One of those faculty was, surprise surprise, Shai Davidai.

The university has faculty & students who physically & chemically attacked students, & we are seeing what has happened to this particular student here being abducted.

Khalil knew that these people were working to bring ICE to terrorize him & wrote an email to the interim president asking for action REPEATEDLY. Shame on this shameful university.

Meanwhile at Harvard, nothing special, just invited leaders of genocidal countries joking about sending exploding pagers to dissenting students during their speech on campus.

CPU code optimization is always fun. Those statements are all true statements:

- Doing more isn't slower than doing less
- Simpler code isn't faster than complex code
- Executing only one logical branch in an if-else isn't faster than executing both branches and picking the right result later.
- Branching isn't slower than not branching at all.

Premature optimization includes also "obvious" things, because you'll be wrong if you don't benchmark it.

It always depends on the exact thing.
