randomgermanguy··on Ask HN: Anyone else disillusioned with "AI experts" in their team?
But why do you think this is? Like is it just the money/status that comes with calling yourself an "AI"-expert ?
randomgermanguy··on The MacBook Air 2025 Is Now Cheaper Than a Random Mid-Range Windows Laptop
If the alternative is a Linux-distro, likely UX won't be much better/more-consistent when applications use different UI kits/styles etc.

Even Though Apple is doing a shitty job with their walled garden, a garden is still more organized than a jungle of different distro's/applications/frameworks/etc.

(at least in my limited experience)

randomgermanguy··on Subway station study reveals fungal communities
Made me instantly think of this: https://www.nationalgeographic.com/science/article/slime-mou...

Something ironically self-referential about not only fungi growing (like) rail networks, but also IN rail networks.

randomgermanguy··on I regret building this $3000 Pi AI cluster
Depends on how heavy one wants to go with the quants (for Q6-Q4 the AMD Ryzen AI MAX chips seem better/cheaper way to get started).

Also the Mac Studio is a bit hampered by its low compute-power, meaning you really can't use a 100b+ dense model, only MoE feasibly without getting multi minute prompt-processing times (assuming 500+ tokens etc.)

I think the only exception is specifically for studying network/communciation-topologies. I've seen a couple clusters (ca. 10-50 Pi's) in universities for both research and teaching.

I personally just throw them at the top of my files as long block-comments, or sometimes inside/around very heavy functions. For example i often add little diagrams for when dealing with some bit-fiddly logic parts to easier visualize the bit-layouts. But for architecture, either a whole text-file for it or at the top of the module

As the other commenters put it, i dont think this is a huge issue. I usually use this for architecture level diagrams, and that shouldn't change often/at-all. In-case it does change, doing a new diagram is perfectly in-scope of whoevers working on that.

Bought this couple months ago, and am now always looking for more ways to include this for inline-documentation.

the fact i can export to clipboard and re-import it and reconstruct all the shapes etc. almost flawlessly is such a big win.

randomgermanguy··on Analyzing Modern Nvidia GPU Cores
Funnily, they're far from being optimal for GEMM ops (especially in terms of power consumption).

For GEMM you need to visit each row/vec n-times so theres a bunch of data-reuse going on, which isn't optimal for GPUs since you can't keep that all so close to your processing-units. And while the tensor-cores kinda implement this i think they don't quite scale up to a full sized systolic array, which is you would want for larger matrix multiplications.

Also just a simpler view: with GPUs most of their silicon is spent NOT tensor-core, so just from that you know its not optimal i guess.

Just referring to that FLOP/s number doesn't really mean much nowadays with tensor-cores and sparsity.

In my eyes the big win of GPUs are that not only are they pretty good at GEMMs but also really good at a lot of other easily parallelizable tasks PLUS they're comparatively easy to program ^^

randomgermanguy··on Getting Started with Torch-Harmonics
Spherical harmonics are used all over the place in climate science. But two big examples are Global oscillations like NAO&ENSO (so ocean currents and atmospheric pressure mostly), and analyzing wind-patterns on the globe/sphere.
