fooblaster··on OpenAI's cash burn will be one of the big bubble questions of 2026
And yes, all their competitors are making custom chips. Google is on TPU v7. absolutely nobody is going to get this right on the first try among their competitors - Google didn't.
fooblaster··on OpenAI's cash burn will be one of the big bubble questions of 2026
There is a pretty big moat for Google: extreme amounts of video data on their existing services and absolutely no dependence on Nvidia and it's 90% margin.
fooblaster··on Show HN: LoongArch Userspace Emulator
I find this all very cool, but why is this useful for game engine scripting. anyone know?
fooblaster··on Executorch: On-device AI across mobile, embedded and edge for PyTorch
Anyway, perhaps we can chat in the executorch discord.

And you wouldn't happen to know about a torchscript replacement that is currently in-flight that is not based on export?
fooblaster··on Karpathy on Programming: “I've never felt this much behind”
Its clear from listening to podcasts/interviews, he does not want to say anything to get on elons bad side. Interviewers appear to also not be eager to broach the subject.

So what are your users doing to get around this? Hoisting all control flow out?
fooblaster··on CUDA Tile Open Sourced
That is true, but that doesn't mean Nvidia is not engaging in engineering to intentionally kneecap competition. Triton and other languages like that are a huge threat and CUtile is a means to combat that threat and prevent a hardware abstraction layer.

Let's see if developers sleepwalk into another trap to keep us locked into nvidia's hardware for the next decade.

Those control flow ops aren't even supported on many backends. I know tensor rt doesn't support them for example, at least today.

Removing control flow isn't as easy as you'd think for some. It essentially means ripping large sections out of python and into separately implemented c++.

I am so confused by metas ecosystem. Perhaps others have the same issues. I have mountains of torchscript code. It worked fine for me - had no issues making the python compatible. Torchscript is now deprecated, and the ostensible replacement is torch.export and either: AOTInductor or executorch. torch.export is so limited - no control flow at runtime at all, less support of python than torchscript. It is far more work to hoist all the control flow out of the model than it ever was to make the model torchscript compatible. Feel like meta has moved on, but I'm still stuck in the past here.
fooblaster··on FPGAs Need a New Future
I think my real problem is that xilinx pushes the gui flows heavily. It is extremely annoying to configure the mpsoc fabrics entirely outside of vivado. Same thing for using any of their bundled IP.
fooblaster··on Ask HN: What are your predictions for 2026?
what he said, but literally the exact opposite of every prediction for me.
fooblaster··on 1.5 TB of VRAM on Mac Studio – RDMA over Thunderbolt 5
Does it actually creates a unified memory pool? it looks more like an accelerated backend for a collective communications library like nccl, which is very much not unified memory.
fooblaster··on 1.5 TB of VRAM on Mac Studio – RDMA over Thunderbolt 5
Might be helpful if they actually provided a programming model for ANE that isn't onnx. ANE not having a native development model just means software support will not be great.

fooblaster··on Horses: AI progress is steady. Human equivalence is sudden
why exactly do you need a deity to tell you to love your fellow man? Do you need god in your life to want to love your children? I think this is not quite right. I don't expect that the desire to create these tools independent of outcome in the valley is simply about greed , and for companies like anthropic, the ability to use AGI fear as a means to drive investment in themselves from VC class that lives the idea of obliterating human labor. We need less money in tech - we'll probably get it soon enough.
fooblaster··on Netflix to Acquire Warner Bros
I watched half of those and I haven't had Netflix in 5 years. it's not worth it anymore.
fooblaster··on Helping Valve to power up Steam devices
yeah this is essentially everything and all this other discussion of corporate structure is irrelevant
fooblaster··on New Glenn Update
Not terribly familiar with the details, but Amazon kuiper has a contract with blue origin and other providers.
fooblaster··on FEX-emu – Run x86 applications on ARM64 Linux devices
How does fex deal with the fact that the memory model on arm is weak and x86 is total store ordering. It seems like would need to hammer performance by putting memory barriers everywhere to handle all cases. Perhaps fex only works when there are well defined mutexes it can gain visibility into? anyone know?
fooblaster··on FEX-emu – Run x86 applications on ARM64 Linux devices
yeah that is correct. The m series chips can turn on total store ordering memory model solely for Rosetta. There's also some hardware extensions to arm to support x86 condition codes in the hardware because it's way more instruction efficient that way.
fooblaster··on I don’t need a Steam Machine
A 5090 is likely 3x the cost of the steam machine. You are at the extreme high end of the gaming market here and not the target of the steam machine.

what's this for?
fooblaster··on HipKittens: Fast and furious AMD kernels
these are not remotely like anything Google uses in the datacenter, even a decade ago.
fooblaster··on Apple M5 chip
I have a lot of the details there. Suffice to say it's a nightmare:

https://www.google.com/url?sa=t&source=web&rct=j&opi=8997844...

AMD is likely to back away from this IP relatively soon.

fooblaster··on Apple M5 chip
The neural engine not having a native programming model makes it effectively a dead end for external model development. It seems like a legacy unit that was designed for cnns with limited receptive fields, and just isn't programmable enough to be useful for the total set of models and their operators available today.
fooblaster··on Apple M5 chip
I think I'd still rather have the hardware area put into tensor cores for the GPU instead of this unit that's only programmable with onnx.
fooblaster··on Apple M5 chip
MLX doesn't use the neural engine still right? I still wish they would abandon that unit and just center everything around metal and tensor units on the GPU.
fooblaster··on Newton: physics simulation engine built upon NVIDIA Warp
I think the bigger deal for founders is that Nvidia can decide at a whim to deny you supply or, better yet give 100 billion dollars to your competitor.
