sojuz151··on Kraków, Poland in top 5 worst air quality worldwide
The air in Kraków is fine once you give it a good chew. I don't know why people are complaining.
sojuz151··on Solving the Problems of HBM-on-Logic
I don't understand why even put that HBM on top of the core.

From what I understand, in a typical gpu core you put logic and connectors on one side and innert silicon on the other. So unless you drill through silicon you don't get shorter routing.

Why not put GPU one one side and HBM on the other side of the PCB? This would fix the cooling problem?

sojuz151··on TPUs vs. GPUs and why Google is positioned to win AI race in the long term
They lose the competitive advantage. They have nothing more to offer than what Google has in-house.
sojuz151··on Should LLMs just treat text content as an image?
This means that current tokenisers are bad, and something better is needed if text rendering + image input is a better tokeniser.
sojuz151··on Quantitative AI progress needs accurate and transparent evaluation
Compute has been getting cheaper and models more optimised. So if models can do something it will not be long till they can do this cheap.
sojuz151··on Eleven v3
Polish is quite good, expected based on the founders' background
sojuz151··on Can rotation solve the Hubble Puzzle?
And the Hubble tension is around 4%, within a factor of 2 of that 10%. This sounds reasonable.
sojuz151··on Carbon capture more costly than switching to renewables, researchers find
Also, with renewable energy sources, the problem is not manufacturing energy per se but getting the energy where and when you want.

For example, you could run a gas turbine in Germany in winter at night during a spike of the consumption and run carbon capture on a desert during the day

In a sense you use atmosphere as battery/transportation system.

I am not saying that this must make sense but this is far more complex than napkin math.

sojuz151··on Why the weak nuclear force is short range
Because in a classical theory, where there are no particles, there is still the same short range potential.
sojuz151··on How does it feel to test a compiler?
What about using multiple open source projects with already existing tests? You check if results of execution are the same between compiler versions? This should also provide you with a better coverage of various features
sojuz151··on Ask HN: How do browsers isolate internal audio from microphone input?
Remember that convolution is multiplication in the frequency domain, so this also handles different responses at different frequencies, not just delays
sojuz151··on TDK claims solid state battery breakthrough
This will have same energy density as TNT. I have a feelings that fully chargred battery of this type might explode
sojuz151··on Gemini Flash
>My intuition is that as contexts get longer we start hitting the limits of how much comprehension can be embedded in a single point of vector space, and will need better architectures for selecting the relevant portions of the context.

We are dealing with multi-headed attention, therefore we have multiple points per token. You can always increase the number of heads or the size of the key vector.

sojuz151··on Ointers: A library for representing pointers where bits have been stolen (2021)
This look like something that debuggers would hate, because following pointers would be broken
sojuz151··on LPCAMM2 is a modular, repairable, upgradeable memory standard for laptops
I would say it would make the most sense to have a replaceable entire ram+cpu+gpu assemble. Just have some standard form factors and connectors for external connectors.

This way, you could keep power consumption low and be able to upgrade cpu to a new generation

sojuz151··on Scientists discover first nitrogen fixing organelle
I don't think so. Biological nitrogen fixation is far too inefficient for this to make sense. Deceased in yield would be too big tfor this to make sense

To give some numbers, just the fixation takes 5.4 more energy, and photosynthesis is 6 times less efficient than solar panels. Moving to biological fixation would also increase water and pesticide usage

sojuz151··on Show HN: Not sure you're talking to a human? Create a human check
Also, you can use this to supplement income. You can herd goat and solve capcha at the same time.
sojuz151··on The end of the dark universe?
This theory is trying to justify MOND, and MOND by itself has many problems. It has problems with explaining the bullet cluster, CMB spectrum, and rotation curves of some galaxies. This paper was not even peer reviewed. This is almost certainly nothing burger
sojuz151··on Apple terminates Epic Games developer account, calling it a 'threat' to iOS
The lose of revenue would not be the biggest problem, they could afford it. The problem would be the loss of applications, most EU based developers would stop supporting iOS and focus on Android. That would hurt
sojuz151··on A quantitative test of Diamond’s axis of orientation hypothesis
My biggest problem is that this hypothesis does not explain why farming started so much later in the Americas than in Eurasia. From Wikipedia "approximate centres of origin of agriculture and its spread in prehistory: the Fertile Crescent (11,000 BP), the Yangtze and Yellow River basins (9,000 BP) and the Papua New Guinea Highlands (9,000–6,000 BP), Central Mexico (5,000–4,000 BP), Northern South America (5,000–4,000 BP), sub-Saharan Africa (5,000–4,000 BP, exact location unknown), eastern North America (4,000–3,000 BP). " and American civilisation were about 4 thousand years behind Eurasia when it come to technology.
sojuz151··on Does DNA have the equivalent of IF-statements, WHILE loops, or function calls?
Alternative splicing is another way of including IF statements. Depending on many conditions some parts of the RNA might be added/removed before the translation
sojuz151··on A* tricks for videogame path finding
TBH running a full A* for each soldier is not only waistfull but also not realistic. Most people are just moving with the group and might not even know where the entire formation is going
sojuz151··on Copyright is not a moral right, it's a monetization strategy
There are some open-source games and fan movies, but they come nowhere near the quality and quantity of the commercial titles. For every tux raacer, there are 5 Mario karts
sojuz151··on Copyright is not a moral right, it's a monetization strategy
Almost all modern games, movies, and tv series would not have been created if there was no profit insentive. And even the book author needs to somehow make a living. Begin able to write books without having to work in some factory for half of your day makes writing easier.
sojuz151··on Copyright is not a moral right, it's a monetization strategy
For convince? There is a single app with all the music, recommendations, and everything. Also, Spotify would be far cheaper. Most people would just use the app with the biggest catalogue, and not a single dime would go to the artists.
sojuz151··on What if Planet 9 is a Primordial Black Hole? (2019)
But the normal black holes have a mass greater than the sun
sojuz151··on Is there a fifth fundamental force of nature?
But the fact that the computation diverges is not a problem by itself. All QFT diverge but this can be fixed by renormalisation. Problem is that for gravity this would require infinity many parameters and the theory could match any observation
sojuz151··on Successful room temperature ambient-pressure magnetic levitation of LK-99
You could run a cable from sahara to the America to send solar power in the night
sojuz151··on Titanic tourist sub photos show wreckage being brought ashore
It is even worse. The load increases with deflation
sojuz151··on Implementing Cosine in C from Scratch (2020)
I would say the benchmarks with lookup tables are bad. In the benchmark cpu will keep the table in cache but in a real program this cache would have to be shared with rest of the code/data. This would either kill the performance of cosine or rest of the app
