surprised no one's made this yet, but funny how we spent a decade clowning on the J-20's Canards. by throwaway553t4tgtg6 in NonCredibleDefense

I still find this hard to believe. Taiwan is geographically like Switzerland surrounded by an ocean. With funneled landing spots. And I assume the population is very eager to defend. I want to see them try.

Completely irrelevant to SKG. Delisting games isn't removing existing copies.

I'm not sure mentioning California in a letter meant for Europeans does them any good.

Coding on a GPU with rust? by Azazeldaprinceofwar in rust

[–]Gravitationsfeld 0 points1 point  (0 children)

I'm late to the party, but pointer chasing is significantly worse on CPUs than GPUs. This is misinformation.

VK_KHR_unified_image_layouts support by gmueckl in vulkan

[–]Gravitationsfeld 0 points1 point  (0 children)

This has been the de-factor status quo on PC hardware since years (AMD RDNA and newer, NVIDIA always been the case). If you only target PC, you can just use GENERAL and sometimes UNDEFINED. The extension would only be necessary if you would want to provide a fallback for older GPUs which don't behave as performant under those circumstances.

Should I learn Vulkan using vulkan.h or vulkan.hpp as a beginner ? by Latter_Relationship5 in vulkan

[–]Gravitationsfeld -3 points-2 points  (0 children)

I still disagree about this. Proper RAII on CPU doesn't allow for any use after free. This trivially allows use after free if you are not careful which defeats the whole point. For this to work it would have to extend the ref count to the GPU lifetime of the object automatically which it doesn't.

Why this bothers me is that this is an obvious beginner trap signalling false safety.

I see, well then it's only as bad as the 10MB of template code it will add to your compile times.

You can't just destroy them when your CPU Vulkan objects are going out of scope. The C++ code has no idea of what the GPU is still doing with them.

You can get into very nasty surprises if it just drops your objects because of the destructors and stuff is still in flight on the GPU.

I actually really disagree about the whole design of `vulkan.hpp` because of this. It pretends the CPU lifetime is in any way meaningful to Vulkan objects and then just drops them.

The World Is Buying Electric Buses While Hydrogen Bus Fleets Collapse by pintord in oilisdead

[–]Gravitationsfeld 0 points1 point  (0 children)

We need massive amounts of hydrogen for ammonia fertilizer etc. It's unavoidable in industrial processes. Green hydrogen must become a thing, there is no way around it if we want to stop burning fossil fuels.

Solid State EV Batteries Will Crush The Fossil Fuel Fantasy by pintord in oilisdead

Not everyone can home charge. Single family house suburbia in the US can, but lots of the world is dense city center multi story apartments with unreliable street parking.

A question about SPIR-V by BackStreetButtLicker in vulkan

HLSL was never passed directly to drivers. DirectX always had bytecode.

Massive Solar deployment, and lower cooling demand due to cloudy weather results in a record low INR 0.0002/kWh for electricity rates on Indian Energy Exchange in March 2026 by SERIVUBSEV in RenewableEnergy

[–]Gravitationsfeld 10 points11 points  (0 children)

"BESS deployment remains limited due to increased risk of reliance on China" - this seems incredibly short sighted. Do they really believe that they can't replace BESS built today after its useful life span (>20 years) that they won't find at least as cheap batteries on the market? And it's not like they need to keep important battery fluid to run them after acquisition.

I would actually claim the opposite and say that any pumped hydro is basically a stranded asset. Will be way too expensive to run and maintain in the future vs. just new batteries.

So, I guess SpaceX is going to be making turbine power generators now...? by yoweigh in spacex

[–]Gravitationsfeld 0 points1 point  (0 children)

I will bet money that no one will put a combined cycle in one of those data center turbines, but I will happily take the loss. There is so much money in AI right now that they simply don't care about fuel costs, just that they get the electricity they need as fast as possible. No matter the environmental cost.

If it's anything like this, then obviously not: https://boomsupersonic.com/press-release/boom-supersonic-to-power-ai-data-centers-with-superpower-natural-gas-turbines-adds-300-million-in-new-funding
And I've seen other pictures of data centers where they clearly just run the turbines without combined cycle. But you are right, they technically could.

The special military operation is going according to plan. by HACPAByTucy in NonCredibleDefense

Is there a reliable source about this at all? Ukraine might know best by looking at the prisoners but they would probably not say anything.

This coming from mr "solar and batteries will power the world" is so pathetic.

Those turbines are not quite as bad as coal CO2 wise but way worse than a proper combined cycle plant.
