wmf··on Apple introduces M6 and M5 Ultra
The bus is also 50% wider so the bandwidth is double.
wmf··on Apple introduces M6 and M5 Ultra
I assume they'll have events for the MacBook Ultra and M7.
wmf··on Apple introduces M6 and M5 Ultra
LPDDR6 is coming.
wmf··on Xiaomi: New CPU matches Apple cores single threaded, much faster multithreaded
Speaking of "us" it seems that Samsung/Mediatek/Xiaomi/Huawei SoCs are not available in the US.
wmf··on Xiaomi: New CPU matches Apple cores single threaded, much faster multithreaded
AFAIK it's mostly self-contained outside of basics like malloc. If you have any evidence to the contrary, post it.
wmf··on Rumoured Apple M5 Private Cloud Compute hardware surfaces online
No, M5 Ultra would have more DRAM chips visible.
wmf··on Qualcomm is now a leader of Linux upstreaming for their SoCs
Does Linux work on X2?
wmf··on SpaceXAI Adopts Nvidia Vera CPU to Accelerate Agentic AI at Scale
You can see the white/silver radiators; they're large but not outrageous. https://www.spacex.com/spacexai/starmind
wmf··on SeL4 security proofs now complete on AArch64
But running Linux on top of seL4 does not take advantage of the capability model at all. You need a new non-unix-like userspace for that.
wmf··on What happens when a GPU reads memory
There isn't really an ELI5 version of computer architecture but you could start with the book Inside the Machine by Jon Stokes. Then you can get into SIMT.
wmf··on Bringing the cybersecurity capabilities of Claude Mythos 5 to more defenders
Hugging Face was able to sign up for Glasswing but they just didn't.
wmf··on Windmill.dev is not "fully open-sourced (AGPLv3)"
Unfortunately AGPL has been a scam for years. It's now an anti-freedom license.
wmf··on What happens when a GPU reads memory
That's probably PCIe DMA initiated by the GPU so I don't think BAR is used.
wmf··on Amazon's Drones Will Soon Deliver to Nearly 500 US Cities and Towns
People get killed crossing the street every day. File an insurance claim and move on.
wmf··on Tactical Computer System (1988) [pdf]
1978?
wmf··on FCC abolishes gigabit speed goal, suggesting it is unfair to slower technologies
You mean they were putting a thumb on the scale and now they're not.
wmf··on Cerebras CS-4
Do you know about Jalapeno?
wmf··on Why crypto's best infrastructure companies stopped looking like crypto?
Noobs like to post summaries of the article as a comment but they don't know that we don't do that here.
wmf··on Cerebras CS-4
Cerebras provides high-speed inference at high cost. It's never going to be the cheapest and thus it will probably remain niche.
wmf··on Cerebras CS-4
Desktop SRAM isn't really viable because it could cost $100K just to load the model.
wmf··on Solo – a .so loader for static Linux binaries
Linux loves to leave papercuts unfixed or undocumented for decades. The solution is to build against an older version of glibc but no one tells you that or how to do it.
wmf··on Cerebras CS-4
I guess because I have actually set foot in a data center I don't imagine literally every product in my home.
wmf··on Who owns the code?
No, but what's the alternative theory?
wmf··on A 25-year-old video patent just expired, ending a legal headache for Linux
For every case like this, there's a patent on an optimal method which forces everyone to use suboptimal workarounds.
wmf··on Cerebras CS-4
Cerebras is only claiming ~2x the performance of Groqvidia which usually isn't enough for people to switch.
wmf··on Cerebras CS-4
162 kW
wmf··on Who owns the code?
I've only seen the Pollock movie but he definitely dripped the paint himself. Are you confusing Pollock with someone else like Sol LeWitt?
wmf··on Who owns the code?
If you mix proprietary human-written code with uncopyrightable public domain code, the result is still proprietary. There's no reverse virality. There's no problem to fix here.

For example, every proprietary OS includes public domain SQLite and it's fine.

wmf··on Who owns the code?
Mix in some human-written code and dare the haters to prove that it's 100% AI. They won't bother.
wmf··on Memory prices climb 500% in 12 months
Memory fabs make a mix of DDR/LPDDR/GDDR/HBM and they continuously adjust the mix to market demand. If demand for HBM drops they will start making more consumer RAM.
