Proposed solution is too expensive with ln and exp calls.

Wuffs is great. I use it in Substrata ( https://substrata.info/ ) for loading PNGs. It is both faster and safer than LibPNG. It's something around 2x faster than LibPNG in my tests (depending on the PNG file), see timi

I have a best-fit allocator for this problem (managing GPU resources). It has higher CPU overhead due to using a std::map, but should waste less space due to not using fixed bucket sizes. https://github.com/glaretechnologies

Not only that, we can't even simulate a single nucleon

I implemented this in my server ( https://substrata.info/ ). Works great. Results in smaller files than zlib/deflate. One thing to watch out for - compression levels >= 20 aren't handled by chrome clients.

Yeah the code looks like a spinlock. It behaves terribly under contention, resulting in performance falling off a cliff as the number of threads increases. Adding more threads actually slows down the total performance. I would fix it if I

Multithreading support in llama.cpp is probably still pretty busted, assuming it uses the same underlying NN inference code as whisper.cpp: https://github.com/ggerganov/whisper.cpp/issues/200#issuecom...

Practically speaking, trying to compress a file is a nice way of measuring... something. I was more talking about the theoretical notion of complexity.

Kolmogorov Complexity does not help with giving a universal measure of complexity or randomness: https://forwardscattering.org/page/0

Why is it wrong?

by Ono-Sendai 3y ago
For all the simulation argument believers, note that we can't even accurately simulate a single nucleus.

Sanitizers only sometimes work on Windows too :)

Superluminal is great as well. I currently prefer Tracy because it gives faster profiling feedback.

There's a bunch of really good C++ profilers already. My current favourite is Tracy: https://github.com/wolfpld/tracy

I think Substrata delivers on all of those things, although it could be faster to download the initial data with a CDN.

Hi John, Substrata is already open source (well, 99% open source): https://github.com/glaretechnologies/substrata As far as scaling goes, fancy scaling solutions are currently in the 'future-problems' basket.

Hi, thanks! I have added a licence file to it (MIT licence).

Have a look at https://github.com/glaretechnologies/substrata/blob/ef48de33... for some (incomplete) notes.

Here's my open source metaverse, which unlike Croquet has an open-source server as well: https://github.com/glaretechnologies/substrata It's out there live, you can visit the world right now via https:/

OpenCL was a perfectly good alternative to CUDA. Unfortunately due to the short-sightedness of programmers using the proprietary CUDA, here we are with CUDA dominant.

Have been dealing with this issue recently. memcpy was quite slow in my tests however, it was ~twice as fast to check the alignment and load as floats (was dealing with floats in my case).

It is pretty hard to measure length contraction when all your measuring rulers also contract, and it's pretty hard to measure time dilation when all your clocks run slow, yes. That is the conundrum of being embedded in the universe :)

Glad you like it. I haven't gone through any of the maths in detail. I do however have a semi-classical electrodynamics computer simulation that I occasionally work on, so why do the maths when you can just run a simulation :) When I

Oh apparently it was Schrodinger himself that wrote about a semiclassical Compton scattering approach: http://www.regels.org/Compton-effect.htm

by Ono-Sendai 3y ago
Not sure what association you mean. Time dilation? length contraction? Both are well supported by evidence AFAIK.

Suprise: i have done first year physics as well. And I am probably more familiar with light-atom interaction than you.

You can have vacuum fluctuations without photons. EDIT: will try and find Compton paper later, going for walk now.
