For the first time in many years it seems building a mid-range gpu dev machine is far cheaper than anything off the shelf or semi-custom and a “professional” grade gpu is actually cheaper than a comparable gaming gpu. Feels good but also idk if I actually want to build my own 🤣

Brussels is nice and warm this time of year… I think I’ll go to FOSDEM. I get in to Brussels Thursday around noon and happy to meet up and nerd out Thursday - Sunday.

Fell in to a quagmire of rounding when I noticed numpy.round(0.5) returns 0. Python's built-in math.round does the same. Turns out this is the correct IEEE-754 rounding mode to round half to the nearest even so round(1.5) returns 2.

Julia also uses IEEE-754 but provides a nice interface to use round away from zero within the same round interface

#rustlang follows c++ std::round to round away from zero. There's experimental support for a function that follows IEEE-754 round to even doc.rust-lang.org/std/primit…

Everyone working at openAI should be ashamed of themselves for empowering this insanity. This is straight up incumbents trying to own a technology relying on lawfare and regulatory capture. They know that open source will get ahead of them if left unrestricted.

Overconfidence about AI is a lot like overconfidence about bikes. Many people are convinced that their mental model of how bikes work is coherent and accurate, right until you force them to flesh out the details.

Journalists who cover Elon Musk have been suspended on Twitter tonight: @Donie O'Sullivan from CNN, Aaron Rupar and the Washington Post's @drewharwell. Rupar tells me he has "no idea" why it happened.

Muting the professors who are arguing over each other on twitter has significantly improved my experience on this app.

Chatgpt wrote a fir filter in c++, created a pybind for me, generated a cmakelists for the project, then optimized the code for avx2. It all compiles and looks correct… I’ll benchmark against using volk dot prod eventually

It was also able to explain aspects of ofdm equalization to me and generate some python code that was more or less conceptually correct including a channel simulator. Struggled with the concept of complex awgn though
