Context: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/... Writes to arbitrary MSR are still allowed by linux, but it'll squawk a warning with the PID from what poked th

Weird, the measurement scale they use does not jive with the scale of the knobs being tweaked. For example, `sched_cfs_bandwidth_slice_us` is adjusted by the project's `bandwidth_size` knob. The default is 5000 us, or 5 ms. But the kno

Tread softly, there are some reports¹ that things like PIM/RIP are not working/not implemented. ¹ https://forum.mikrotik.com/viewtopic.php?t=180896

Would you considered using intel_pstate=passive, and then use x86_energy_perf_policy/cpupower to turn the knobs on how to influence the governor? This'll let the CPU do its lower latency internal frequency changing. But of course,

Oracle spelled backwards, "El Caro", is Spanish for "expensive". I can never forget this tidbit when dealing with Oracle.

I wonder if part of this pricing scheme is to counter (or at least to short-term profit from and eventually change the behavior of) the provider being abused by spammers/scammers who could previously scoop up benign reputation IPv4 add

Pinning to the physically closest core is a bit misleading. Take a look at output from something like `lstopo` [ https://www.open-mpi.org/projects/hwloc/ ], where you can filter pids across the NUMA topology and tr

There is at lease one open issue¹ with the clipboard crate that causes a high amount of wakeups (under Wayland at least). Whatmore, the wakeups scale with the number of terminals open. The project is ruthless about performance[latency] regr

Be advised that there is still an issue in the QTWayland front that makes OBS in Wayland rather unpleasant in practice; https://bugreports.qt.io/browse/QTBUG-81504 (via https://github.com/obsproject&#x

A project to keep an eye on, to replicate 'autotype' support offered by many password managers, is wlrctl¹. A popular alternative is ydotool², but brings some additional risks the operator might not be comfortable with. ¹ https:&#

'Purple' sounds like the 'Display options>Merge exe, comm and cmdline in Command' setting, hotkey-able with `m`. Yeah, echo'ing to the UI which hotkey was just activated could be helpful.

Yes, ACPI DSDT being utterly broken seems to be a pretty common trip point for Linux suspend/sleep. For my Dell Precision 5510, I was able to patch[1] a missing device back into the DSDT, as well as 'fix' some thunderbolt por

A somewhat lighter-weight approach with PulseAudio (vs running full-blown PulseEffects) can be achieved through the use of ladspa-sink plugins, as described briefly on the Arch wiki for dynamic range compression https://wiki.arch

Another technique to dynamically manipulate task isolation is through the kernel's 'cpuset' interface ( https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v1... ). Coupled with thread
