p_l··on AMD's Zen 6 Family: Feeding the Beast
Apparently it is nearly possible electrically for some EPYC/Threadripper combinations, but requires considerable investment on the motherboard side - muxing different firmware types, analog and digital logic to detect CPU type and modify some of the connections (including different VRM configuration)

So, possible to do by motherboard vendor, not necessarily enforced by AMD, expensive

p_l··on AMD's Zen 6 Family: Feeding the Beast
The real issue is that the cost is not really on AMD - the cost is on motherboard vendors - more complex routing, thicker PCBs, etc. - all adds up.

A pin on underside of CPU is reasonably cheaper especially with how they've got a sea of wires working for the humongous models replacing previous serdes-based approach

p_l··on Synaptics patent claims stop work on DisplayLink drivers
In many cases companies do, in practice, exploit other parties lack of law knowledge.

Also encountered many cases where a company simply didn't consider actually vetting what they put on contract against local law

p_l··on Synaptics patent claims stop work on DisplayLink drivers
That's not universal, and it's why certain terms are nearly never brought to court because everyone knows they will be laughed out and then they will have to change lots of EULAs for regionally illegal claims
p_l··on Gemini 4 Carbon is now available
The complaints about availability are at least somewhat true given the thoroughly brain-dead idea of announcing a model when it's released only to a very exclusive group - since it kills any positive rumours.

But I concur with the question about hallucinations. Worst I ever got since 3.7 flash if not earlier was model drifting too far when working on something very much new to itself and not being critical enough, something mk ostkt fixed by adversarial critical review subagent

Memory controllers are pretty much limited by external pinout.

Zen 4 and newer consumer chips have 4 memory controllers (for legacy reasons shown as 2) which handle 32bit wide LPDDR5 or DDR5 interfaces (2x per dimm for DDR5)

The AM5 (desktop) socket has in addition to the 4x 32bit memory lanes, 28 PCI-E lanes (generally 16x for GPU, two 4x general purpose, one 4x to chipset), 4x combined DP/HDMI outputs, USB 2.0 port, 4 USB 3.2 Gen 2 ports. And that's just the major buses, there's ton of other components exposed (simpler IO, sound, power)

All of that counts to staggering 1718 pins - anyone remember when moving dual-channel K8 from 940 pin to 939 allowed removal of whole layer from motherboard PCB, making them way cheaper?

The high-end performance server socket from AMD has 6096 pins, significant chunk of it being the 24x 32bit DDR5 interfaces.

So unfortunately it's very much not easy to add more memory, and that's before considering issues with routing it on motherboard even if you accept changing shapes

Antigravity is the obvious choice, unless someone manages to scrape out its prompts and API patterns then evals something better

I had some reasonable success running teamwork with argon orchestrator, 3.8 Flash implementor subagents, and follow up Argon/flash subagents running uno-reverse skill, mixed up with /goal

I found out when I opened Gemini app on phone and it showed Carbon Medium as default
p_l··on Your TV can see through walls (2025)
Funnily enough, first time I've seen it mentioned was in Ghost in the Shell manga from 1990s, where Major's side business illegally offers military grade optronic touch/etc senses in artificial skin for cyborgs, using measurements of bending fiber optic loops
p_l··on Claude Fable 5.2 and Mythos 5.2
It's one of the options, but not "oh superintelligent AI comes in and we mostly know what that means so we want to speedrun it " - which I'll admit I was not very clear on.

In fact, one of the options Vinge considered was a "group intellect" formed from how humans communicate more thanks to internet

p_l··on Claude Fable 5.2 and Mythos 5.2
The older, original definitions of "singularity" were less about "herp derp superintelligent AI blah blah".

and just about "we cannot really predict beyond certain things" (Vinge's "Singularity" (1993) with its "opaque wall across future")

p_l··on Claude Fable 5.2 and Mythos 5.2
Dune books by Frank Herbert never actually went into what "Butlerian Jihad" was.

The semi-canonical Dune Encyclopedia (disregarded by Frank's son) differs vastly from prequels and generally points to it being a self-inflicted wound on humanity that opened the doors to widespread return of feudalism and essentially stopped humanity for a 10,000 years

p_l··on Every Windows 11 app should kill Electron, and Discord just showed why
It was not "bad default settings", like often with UE5, it was "MS did a superb job making VSCode not dog slow like Atom" and it took really lots of work
p_l··on AMD expects to outsell Intel in Q4 for the first time in history
They used the same tricks when AMD landed useful 64bit mobile CPUs (turion X2 series and the like). But by zen era even big box retail is selling and models
p_l··on AMD expects to outsell Intel in Q4 for the first time in history
It's due to ROCm, think equivalent of CUDA lower level drivers, which is well problematic.

There's huge upswing in using Vulkan Compute which works across NVIDIA, AMD, and Intel (and even others), and which is apparently much easier and stable to run on AMD

Yep. Picked 32640 because the last two values are, from my understanding, inconsistently handled by transmitters due to how far from norm they are.

You can self-host the LLMs involved, API key is only if you're using nvidia-hosted
p_l··on Jobless tech workers are being left out of San Francisco's AI boom
Part of the offshore story is why I have way less care for big name journalism complaining about AI job loss or the like.

I remember their cheerful atmosphere about "geeks" getting pushed back down thanks to offshoring

32,640 fpm is the maximum ADS-B can encode for vertical speed.

Quite likely it exceeded that, some sensible numbers I've seen suggest between 800 to 1000 km/h final speed at impact

p_l··on Private Jet plane crashes in Florida
This kind of impact in fact has tendency to turn aircraft into powder

It's not even cockpit audio, it's just from ATC radio : - \

The speculated final velocity at time of impact greatly exceeded design parameters for black box survivability so...

Same here - just started to really get going with herdr not sure I want to worry about moving again
p_l··on We're releasing the weights of Mistral Large 4
Unfortunately I can't link to IRL discussion with lawyer (wish it was so easy!)

We got guidance that:

a) weights should be considered to be public domain due to "blender" aspect of training on otherwise copyrighted data (similar argument as to why stable diffusion weights can't be infringing - because any specific copyrighted work provides less impact on process than RNG)

b) model outputs should be considered public domain as far as "work done by model" counts - prompts/inputs done by human are copyrightable.

However, model output can infringe - essentially same framework as if you used a ton of Disney stuff in a drawing you made by yourself - since the drawing would remain what it is without the copyrighted information, it is infringing even if you did it from memory.

Similarly any human-made addition to model output are copyrightable, but to make an useful distinction there would need to be some significant work. So let's say you made an image that incorporated model outputs for parts of it - going back to "prompts" it also counts if you made a sketch/wireframe/etc. and then used a model to "fill in" or postprocess it.

Unless considerable amount of lobbying reverses it in a new directive/regulation, that's the case on model outputs - Originally I learnt of it from briefing prepared by lawyers regarding EU laws on AI.

In EU especially it's already settled, afaik, as are direct model outputs
p_l··on Gemini 4 Carbon is the new #1 on the Artificial Analysis Intelligence Index v5
I guess it's also because the model is available to at least one group, and this releases embargo on information about it.

The point of the lower pricing is to move compute (and sysadmin) capacity around

Nah, Elon is well reported to have been crazy about "X.com" since ~2000 and thus it makes sense it got incorporated into SpaceX name
