A thing happened that I had been vaguely worried about - my kid read my website 😬

New article! What do you do when profiling your code shows the slowdown isn't in your code, but deep in the kernel? Why, you grab the kernel source and go spelunking.

How a routine profiling session turned into a Linux kernel patch:

From profiling to kernel patch: the journey to an eBPF performance fix | Ritesh Oedayrajsingh Varma

A story about how an innocent profiling session led to a change to the Linux kernel that makes eBPF map-in-map updates much faster.

HEY EVERYBODY! We're doing REAC again and we are announcing call for submissions! Please come and talk about interesting problems! From the call:

"Talks about pipelines, workflows, culture, hard-earned lessons from the experience of engine-making, experiments and failures - all the topics that are fundamental to our craft, but hardly feature in traditional computer-graphics venues, are welcome.”

We look forward to hearing from you!

Google LLM assistant really struggles - they should be able to make this kind of interaction bulletproof and I don't understand why it's like this? I asked for a simple reminder and it messed up the time math, off by roughly 12 hours.

@TomF @dotstdy @archo Turnkey sampler feedback failed the "no implicit behavior" test of inserting bits into your shaders, as well. But the primary piece is as you note, that your predictive heuristics are needed and Good Enough(tm). The most interesting uses for sampler feedback are actually for offline analysis in tooling to build offline CPU-side predictive guidance hierarchies/etc. for your streamer.

@wadeb is on here if you want to ask specifics about COD on-demand texture streaming.

It's @themagpi day. I've been busy in this one. A revised troubleshooting guide for Raspberry Pi 5 and Bookworm plus how to convert an old smart speaker into a Pi-powered muti-use audio powerhouse. Happy Birthday #RaspberryPi !
We can go further.

I've just finally had time to read a great post about using ChatGPT in real life by @BartWronski and if you are sceptical about it as tool: just spend a little bit on reading it. It's a non-bullshit post and basically describes also my uses 👍

How I use ChatGPT daily (scientist/coder perspective)

We all know how the internet works—lots of “hot takes,” polarizing opinions, trolling, and ignorance.  Recently, everyone has opinions on AI and LLMs/GenAI in particular. I won’t focus here on…
