> heat-pump equipment costs roughly €500,000 per megawatt of installed capacity Interestingly enough the price for these giant heatpumps is pretty much in line with domestic ~10kw …

That is comparing an all to all switched Nvlink fabric to a 3D torus for TPUs. Those are completely different network topologies with different tradeoffs. For example the currently…

It's the one exception in the semiconductor supply chain where Europe is still leading. For all other parts of the value creation Europe is either a niche player at best or complet…

The hardware is heavily optimized for low precision matrix math, pretty much only used for AI.

> to OpenAI's model gpt-4o-mini Why a model specifically distilled down for logical reasoning tasks? I would expect larger models to produce a wider variety of outputs.

But these social third places have also shifted. Younger generations aren't going out as much but e.g. playing video games specifically with other close friends is very popular.

Inference throughout scales really well with larger batch sizes (at the cost of latency) due to rising arithmetic intensity and the fact that it's almost always memory BW limited.

If it's just filtered out in the training sets, adding the information as context should work out fine - after all this is exactly how o3, Gemini 2.5 and co deal with information t…

Something where you're reachable for any legal purposes- in Germany this sadly remains a physical address. There are various service which offer a 'virtual' address with digital fo…

There's still a throughput/latency tradeoff curve, at least for any sort of interactive models. One of the reasons why inference providers sell batch discounts.

There's also big efficiency increases when batching multiple requests, making clouds inherently more cost effective for normal use cases. Way better utilization of expensive hardwa…

Mixture of experts involves some trained router components which routes to specific experts depending on the input, but without any terms enforcing load distribution this tends to …

It's not quite waste heat because the cold side of thermal power plants wants to be colder than district heating temperatures for best efficiency. There is some loss in electrical …

Used to be a common thing for storing analog signals in the past :) https://en.m.wikipedia.org/wiki/Delay-line_memory

Apparently Chinese mainstream silicon PV modules are already a bit cheaper at ~0.14USD/W right now. Article doesn't talk about efficiencies but it seems production perovskite modul…

Has been really common in HPC for quite a while. I presume the higher interconnect/network of hpc favour the higher density of liquid cooling. Hardware utilization is also higher c…

Poland was dealing with similar brain drain problems, but now that economic opportunities are there educated people are returning.

Intels surprisingly fast 14nm processors come to mind. Born of necessity as they couldn't get their 10 and later 7nm processes working for years. Despite that Intel managed to keep…

If you invest a lot of money into very expensive Nvidia training hardware you certainly want to run them as close to 24/7 as possible. Dispatchable load usually means oversizing th…

The API and featureset so far looks like a one to one reimplementation of JAX without the jit functionality. What does this do differently? AFAIK Jax has an experimental apple GPU …

The article is about building costs per mile. If anything lower density should make construction simpler.

If everything goes to plan the whole thing is pretty clean - all the dangerous products stay contained and ideally don't ever interact with the overall environment. And the space e…

The cuda cores of Nvidia GPUs are closer to fp32 units in vector ALUs than CPU cores capable of operating independently in parallel. Following that definition a modern CPU core wou…

Modern Thermal power plants reached Thermal efficenies of 45-50% for coal and closed cycle gas turbines. ICE cars have a hard time reaching 25% under normal conditions. Additionall…

The same reason that France is utterly failing at building flamaville 3 - it's not a technical problem but of regulation, government and public support.
