• Why AI is stupid garbage and everyone in the industry is lying frantically to cover up the truth. (Ars Technica)
  
  Okay, I may have paraphrased Tim Lee at Ars just a little there, but if you look at the promises AI leaders have made against the mathematical problems they face, that is the gist of the situation.
  
  AI - LLM-based generative AI, not the more interesting discriminative AI - uses a technology called transformers which lets it process data in a massively parallel way. This requires about the same amount of work as a traditional neural network on simple prompts, while being able to use highly parallel hardware like graphics cards, so you get the result much faster.
  
  For simple prompts:

  The longer the context gets, the more attention operations (and therefore computing power) are needed to generate the next token.

  This means that the total computing power required for attention grows quadratically with the total number of tokens. Suppose a 10-token prompt requires 414,720 attention operations. Then:

  • Processing a 100-token prompt will require 45.6 million attention operations.
  • Processing a 1,000-token prompt will require 4.6 billion attention operations.
  • Processing a 10,000-token prompt will require 460 billion attention operations.

  So as you make your question more detailed and specific, the amount of time taken to produce an answer increases rapidly.
  
  Work is now on to replace transformer models with classic neural networks, which don't have these limitations, but also don't have the magical ease of development of the transformer model.
  
  But that means that promises of AGI next year are simply lies.

• Embodied, the startup that produced an $800 robot for children and has now run out of money, is working to release code and documentation to allow hackers to keep the robots working after the company shuts down.  (Ars Technica)
  
  Good to hear.
  
  
  
• The jury in the Arm vs. Qualcomm suit has sided with Qualcomm on two of the three questions put to them.  (Yahoo)
  
  Qualcomm, which has a license to produce Arm chips, bought startup Nuvia, which had a license to produce Arm chips. 
  
  Qualcomm then produced chips based on Nuvia's design.
  
  Arm sued Qualcomm saying Qualcomm was not licensed to do that.
  
  The jury verdict said Qualcomm did not breach its Arm license in buying Nuvia or producing the chips - which are used in the new Arm based laptops which are not selling particularly well so far.
  
  They did not reach a verdict on the question of whether Nuvia was in compliance with its Arm license.  I'm not sure how relevant that is, though Arm plans to continue legal action.

  Electric van maker Canoo is not looking too healthy.
  
  
  
• What is Broadcom doing with VMWare?  Slashing costs.  A lot.  (Ars Technica)
  
  Not making many friends in the process, but they can worry about that after taking a dip in their swimming pool full of money.  Based on the latest figures sales have increased only slightly, but costs have been cut in half.
  
  In addition, Broadcom has effectively killed the VMWare reseller market, so that if you want to migrate your company off VMWare, you need to get technical support from Broadcom.

• Here's a list of the 49 American AI startups that have raised $100 million or more in 2024.  (Tech Crunch)
  
  Top among them is OpenAI, which raised $6.6 billion this year, but close behind is Elon Musk's xAI, which raised $6 billion.
  
  Interestingly Europe didn't miss the boat with Mistral leading the table there with $1.2 billion raised.
  
  What all that money will achieve I don't know.

• For consumer hardware, it's not achieving much.  (Tom's Hardware)
  
  AI PCs just aren't selling.  That is, people are buying PCs, and some of them are labeled "AI", but nobody is buying a PC because it is labeled "AI".
  
  Notable Qualcomm's sales of its new Arm-based Windows laptops can be best described as meh.
  
  
  
• Meanwhile here's an M.2 card that contains a 24 TOPS AI accelerator.  (Tom's Hardware)
  
  More precisely, four 6 TOPS accelerators.
  
  Why?  I don't know.  But it costs $149, which is reasonable if you need one.
  
  
  
• How types make hard problems easy.  (Mayhul)
  
  Yes, thank you.  We figured this out sixty years ago.  Then JavaScript happened.

• Microsoft promises meanwhile to keep nagging you to use passkeys rather than passwords online.  (The Register)
  
  A passkey lets you log in to a website without the tedious logging in part, so long as you have already logged in to your device.  This is actually fairly secure because the passkey consists of two parts - you have one part and the website has the other - and nobody can steal your password from the website and hack your account because effectively they only have half the password.
  
  But if they hack your laptop, you're hosed.  Though that is true regardless.

Rather, the lesson is simply that humans are human, and online, their behavior is shaped by both the prevailing norms in their community, and whether rules constraining that behavior exist and are enforced.

  So what he is saying is that left-wingers are particularly violent.

• What happened to ChatGPT the other day?  It wasn't DNS, but it wasn't not DNS either.  (Try Parity)
  
  OpenAI deployed a new system that had been running happily on their test servers for some time.  About twenty minutes in, things started going horribly wrong, with the monitoring system that reports on all things production taking over and then taking out the production servers, because it had a hidden scaling problem that never showed up on the smaller test environment.
  
  And with the monitoring process eating up all the bandwidth on the control network, the simple changes they needed to make to fix the problem couldn't be done because OpenAI's internal DNS was down.
  
  Lesson of the day: Hard code all your IP addresses in your software.*

• The Minisforum MGA1 is an external graphics card / dock thingy that dramatically speeds up laptops and mini-PCs except.  (Notebook Check)
  
  It's about as fast as a laptop version of the RTX 3080, but can only be connected via OCuLink.  If your laptop or mini-PC doesn't have OCuLink - and most don't - it's a paperweight.
  
  OCuLink is pure external PCI Express, so it's simpler, cheaper, and faster than Thunderbolt, but also a lot less common.

• Zotac has leaked Nvidia's new RTX 5000 series graphics cards.  (VideoCardz)
  
  The lineup includes the RTX 5090, which you can't afford and probably won't be able to buy anyway, the 5090D which is a China-only edition for communists, the 5080 which will probably be overpriced and you won't want, the 5070 Ti which will probably be decent but expensive, and the 5070 which has 12GB of VRAM like the Intel B580 but which will definitely not cost $250 like the Intel B580.
  
  The new cards all reportedly use GDDR7, so memory bandwidth is likely to be significantly better than 4000 series cards.  GDDR7 memory uses trinary rather than binary signals - a technique known as PAM-3 - so it can move data 50% faster at the same clock speed.
  
  Thunderbolt 5 also uses PAM-3 encoding but right now it's kind of useless so we should hope that's not a sign of things to come.

  Now you can plug a different module in that holds two extra M.2 slots, and the good part is the module only costs $39.

• A major laptop manufacturer is expected to show off an ion drive at CES.  (Tom's Hardware)
  
  The Frore Airjet uses a piezoelectric element to silently produce an airstream to cool whatever it is attached to.  The problem is that it is not particularly power efficient - only about one fifth as effective as laptop fans, which are not themselves paragons of efficiency.
  
  The Ventiva ICE is an ionic engine.  Also silent, it ionises the air molecules to attract them to a metal grate, where they are deionised but keep right on moving, creating an airflow which cools your laptop.
  
  This isn't the first time that someone has come up with this idea, though, so we're going to have to see whether they can make it work.  Previous efforts have been very sensitive to dust buildup, which is enough of a problem with fans but renders ion blasters useless.

• TSMC has announced performance specs for its upcoming 2nm node.  (Tom's Hardware)
  
  Compared with the current leading-edge 3nm process, it uses 24% less power for low-power mobile chips, and 35% less power for desktop chips.  Or if you keep power the same, it runs about 15% faster.
  
  Compared to 5nm, it uses around 48% to 55% less power, and compared to 7nm (which I'm running right now), the reduction is as much as 70%.
  
  Chips will be coming off the production line in 2026.

• Intel's second-generation "Battlemage" graphics cards are here and...  They're actually pretty damn good.  (Hot Hardware)
  
  They're not perfect: Intel's drivers still hiccupped on a couple of games, resulting in slower than expected performance and some visual artifacts.
  
  But the new B580 routinely outruns Nvidia and AMD cards costing 50% more.  And it leaves Intel's previous generation A770 card in the dust on most tests, while using about half as much power.
  
  And it delivers solid ray-tracing and AI performance.  And it has 12GB of VRAM instead of the 8GB found on competitors like Nvidia's 4060 and AMD's 7600.
  
  And it's cheaper at $249.
  
  All in all, a good card at a good price, only let down by some minor driver issues.  But the driver software has improved dramatically since the first generation of cards was launched, so those problems are likely to be fixed too.
