New comment by treprinum in "The Tsunami of Burnout Few See"

treprinum — Sat, 11 Jan 2025 22:59:19 +0000

I would suspect the physiological base of burnout is the depletion of mainly B vitamins in the brain. When you look at the Krebs cycle, the main energetic reaction in every cell, B vitamins play crucial role whether they act as catalysts of enzymes (B1, B2), provide electron transport (B2/B3 to FAD/NAD+) or are required by sub-processes of the cycle (B5, B7, B12). Being under constant stress is known to deplete B vitamins and at some point their lowered availability starts inhibiting higher cognitive tasks in favor of just survival. Diagnosing this is problematic as serum levels don't tell much about tissue levels.

Didn't Chinese scientists recently show a crazy success rate (~90%) of treating advanced Alzheimer/dementia by performing a microsurgery of the neck, allowing brain to dispose accumulated waste?

Nvidia just did what Intel/AMD should have done to threaten CUDA ecosystem - release a "cheap" 128GB local inference appliance/GPU. Well done Nvidia, and it looks bleak for any AI Intel/AMD efforts in the future.

Bad idea for social marketing - by the time a post becomes popular, it disappears.

Get admitted to online UIUC iMBA or BU OMBA, take the marketing/sales/entrepreneurship courses, quit.

That's a pity! CGTalk was the site where I first learned about Cg from Nvidia that later morphed into CUDA so unbeknownst to them, CGTalk was at the forefront of the AI by popularizing it.

treprinum — Tue, 31 Dec 2024 20:09:01 +0000

Would that mean that we would need to exchange latent "embeddings" between various "reasoning" models for emulating thinking and an LLM will be just about converting to/from human language when interfacing with mere humans, at some point in the future?

I am really glad we are finding new pieces of the puzzle of how our gut works and perhaps can someday understand their effect on immunity, neuro-degeneration, cancer etc. for which we now only have accidental findings.

I said in some areas of Barcelona which is true. Now somebody did the Simpson's paradox using the whole data set instead of conditional data, leading to a different result.

So you cherry pick one real-world observation, try to refute it and it makes the rest wonderland? EU is doing super great because you just scentifically proved that Barcelona can't be as bad as LA?

New comment by treprinum in "Is Iceland getting ready to join the EU?"

treprinum — Mon, 30 Dec 2024 01:53:54 +0000

No, but EU with all its social agenda is now imploding at unusual places that were once considered great places to live, inflation is doing its thing. In the US tech is considered the most important engine of the economy, EU wasted over a decade and lost its only competitive company that led one large sub-field of tech (Nokia). Pretending nothing is going on won't help the EU, sooner or later this will be apparent everywhere (with a chance a hot war with Russia collapses it quicker).

Why would anyone outside some desperate eastern European countries want to join? EU is going down hard, since 2008 no meaningful GDP growth, flat salaries, no tech companies propelling growth, old population, all the while US and Chinese GDP is exploding. The only thing EU has is regulation and high taxes, everything else is deteriorating quickly and the rate of decline is accelerating. Barcelona, previously a jewel of Europe, now has as many homeless as LA in some areas.

New comment by treprinum in "Making AMD GPUs competitive for LLM inference (2023)"

treprinum — Wed, 25 Dec 2024 21:33:59 +0000

The top-end RDNA4 GPU will have 16GB RAM. That's a massive regression compared to 7900XTX and performance-wise it should be at best at the 7900XTX level. We are discussing AMD cards for LLM inference where VRAM is arguably the most important aspect of a GPU and AMD just threw in the towel for this cycle.

AMD decided not to release a high-end GPU this cycle so any investment into 7x00 or 6x00 is going to be wasted as Nvidia 5x00 is likely going to destroy any ROI from the older cards and AMD won't have an answer for at least two years, possibly never due to being non-existing in high-end consumer GPUs usable for compute.

Best way is to use ChatGPT + Whisper + ElevenLabs and a prompt where you tell the LLM to answer in German but to tell you what mistakes you made and what you should have said instead in your own language. Instead of this lazy "immersion" method German schools use in order to avoid speaking in any other language so students never understand what went wrong.

Tor browser asks you if you want to allow fingerprinting or not when a site attempts to query your HW info. Not sure why other browsers can't do the same.

I remember somebody complaining about it on reddit, unable to overcome some BIOS limitation on an AMD G processor. Even on M3 Max one had to issue a special command to enable GPU to access more memory.

Quantized sure but there is some loss of variability of the output one can notice quickly with 30B models. If you want to use the fp16 version you are out of luck.

Problem with MI300x is the price. Problem with 7900XTX is that it's at best as good as Nvidia with the same RAM for a similar price. If 7900XTX had e.g. 64GB of RAM, was 2x slower than 4080, and kept its price, it would sell like crazy.
