After many months of planning and development, here it is. Introducing btype. B-tree based collection types for Go. It's hand-crafted to be faster than the current B-trees for Go, Rust, and C++. github.com/tidwall/btype
Tomorrow I’ll be giving a talk at Bsides Varaždin titled "Caveats of Using eBPF in Linux". If you're interested, you can check out the slides here: dkorunic.net/pdf/Kor... Feel free to stop by, listen in, and join the discussion! #ebpf #linux #sysops #kernel
Astrophotography has a quiet magic I didn’t expect. Valentina and I have been spending our nights under the stars, and this is what came out of it: ~700 frames, 20s each, capturing Bode’s Galaxy. Curious to hear what you think ✨

A tale about fixing eBPF spinlock issues in the Linux kernel | Ritesh Oedayrajsingh Varma
A system freeze led us deep into Linux spinlock internals, where we helped find not one but three bugs in the kernel's resilient locking code used by eBPF.

In my spare time I’ve been improving the eBPF code in github.com/dkorunic/... . What helped most was a colleague running ancient Linux kernels - it pushed me to go the extra mile working around CO:RE limitations and filling gaps in my own knowledge.
