Interesting #xorg #xserver #userspace #hack left in the #linux #kernel because of #popular #broken #code https://www.phoronix.com/news/Linux-DRM-.. It means that all #programs that start with the letter 'X' are run completely differently from other #software . Potentially could have been used for #malware or something!
#iouring seems to be exceptionally powerful in increasing #networking #speed by reducing #userspace to #kernelspace #copying https://lwn.net/Articles/879724/ Lots of #excitement in the #hackernews #comments regarding this new #feature https://news.ycombinator.com/item?id=301.. Very cool indeed. It will have *massive* implications across all parts of the #linux #kernel !
The #intel #spectre mitigations for their crappy #cpu design are causing all sorts of optimization problems: https://robert.ocallahan.org/2021/06/spe.. The 'solution' is to execute *more* instructions in #userspace as there is a serious cost for each #systemcall ! Intel are really being punished for this now thought, as I posted recently #amd is eating their lunch because of this.
