DavidR:
* Not much new, I continued to work on the new disk and cpu plugins
for ksysguard
* Making it also work on freebsd
* I have now disk read/write rate on FreeBSD, too which the old code didn't have
* Also mapped intel temperature sensors to individual cored
* Merged using sock_diag kernel interface instead of /proc/net parsing
* https://invent.kde.org/plasma/ksysguard/-/merge_requests/31
* and fixed a rendering glitch of tooltips when the window becomes very small
* https://invent.kde.org/frameworks/plasma-framework/-/commit/8c37d1d225adc68cf886cd22b4191828d6f58b0b


Arjen:
* I spent most of last week looking into improving the performance of
the process table in plasma-systemmonitor
* initially I tried to move everything in the linux backend of
ProcessCore to separate threads, but that turned out to perform worse
:(
* but I did find out that reading /proc/pid/smaps_rollup is very slow (200ms+)
* So I moved only that to a non-blocking threaded operation, which
seems to improve things
* https://invent.kde.org/plasma/libksysguard/-/merge_requests/64
* also found out that the javascript callback in KSortFilterProxyModel
is a bottleneck for the process table
* so I created a c++ version of that, which improves performance more
* after that I spent a bit of time trying to remove some aliasing
artifacts in Quick Charts' line chart
* first version apparently made things worse on non-amd gpus but now I
have something that should work correctly on all gpus and also works
correctly on high dpi


Bhushan:
- Debugging various issues with maliit-keyboard
    - Keyboard not respecting the ImHints (partially fixed, needs
      refactoring before gets committed)
    - Keyboard getting stuck randomly (so far debugging why this
      happens)
    - Close keyboard when focused app goes away (short patch, need to
      put it up for review)
    - Keyboard showing up with wrong size at first startup
- Oh and also gave talk at Linux Plumbers Conference about plamo \o/
