New blog post for those who are curious about performance of BPF programs:

https://t.co/gZzNP208ot

We talk about topics like Instructions Set versions, Top-Down for BPF and simple modeling.

I just finished reading @lizrice's "What is #eBPF?", an easy-to-read introduction to eBPF for non-sysadmins (like me) https://t.co/4cJeO7N5ZH

It got me interested in trying to get my hands dirty as I'm a learning-by-doing guy

Tejun Heo proposed a "BPF extensible scheduler class" for the #Linux #kernel's process scheduler which allows scheduling policies to be implemented as #BPF (aka #eBPF) programs: https://t.co/Yq3cZPqsvu

Trying out Python 3.12's support for Linux #perf (https://t.co/U4qBZq0uSD), along with JIT compiled C++ code and CLING_PROFILE=1 from ROOT to make it more fun. See full flamegraph at https://t.co/gIIrKzGYFl.

@andrewbrown I can't remember how many times I've compiled MySQL or another app in a certain (more debuggable) way, populated a database, tried a workload, no another workload, no another...just for one tool screenshot!

Kill program that access to /tmp/secret.txt #eBPF

bpftrace --unsafe -e 'tracepoint:syscalls:sys_enter_openat { if (strncmp("/tmp/secret.txt", str(args->filename), 15) == 0) { signal(9); }}'

More @HarfBuzz study: "The case of the slow hb-ft h_advance function"

https://t.co/EkKQMV6LXy

I investigate why measuring the horizontal advance-width of glyphs via FreeType font-functions in HarfBuzz is ten times slower than using the internal HarfBuzz font-functions.
