zig related io_uring benchmarks: github.com/coilhq/tiger-b… What is often overlooked, but I believe the most important change, is quoted in there too: "What is unique about io_uring here is that the same simple interface can be used for both file system and networking I/O"

Contrary to common belief, a #Java object's identity hash code is not necessarily related to its memory address. Instead, values are obtained via a configurable strategy. On OpenJDK, by default, it's a random value. Details in this post by @alidehghanig: alidg.me/blog/2020/7/15…

I am working on Eclipse Collections version that would use offheap or mmaped ByteBuffers. EC already have many concepts from MapDB4, and is good starting point for new MapDB version.

Nice talk about Buffer Trees (aka Cola trees, Fractal, B-Epsilon). Congrats to authors for good implementation, but for me this stuff is just to complex. I hope I will be able to replicate some benefits with storage log buffers, on regular BTree. youtube.com/watch?v=1gOlXf…

I am looking for Linux laptop, that can do 1000 nits and 64GB RAM. Is there a reasonable way to get HP Dev One in EU? #HPDevOne

Looked into HP Dev One laptop more. It has some sort of privacy screen filter, so 1000 nits is not really brighter than normal 400 nits laptop. Also bad battery life. Really disappointing. #HPDevOne youtube.com/watch?v=7oZLyH…

I'll be happy to talk to teams that currently work on languages targeting 100K+ users and figure out how I can help. Probably, no full-time commitments, but I'm pretty sure I can be useful in many other ways. 2/2
