Yeah, cryptocurrency stuff is the closest I've ever felt today to the spirit of the old internet.

SETI@home is in hibernation

Re: SETI@home is in hibernation
#92I have a tangential question. I remember distributed processing being a "next big thing" back in the day. The idea was that a company could run complex operations by borrowing some power from all their employee's computers. Seti@home proved the concept was possible. So what happened? Why can't I train a random forest across all the computers currently logged into my company's VPN?
Re: SETI@home is in hibernation
#93This makes me sad because it reminds me of something similar I just went through. For the last few years, I've been running >120k gpus to mine ETH. Before we turned them off after ETH switched to PoS, I tried really hard to find an alternative workload for them. A large number of the GPUs were based on the PS5 chip, which is an APU (CPU+GPU) and ran as blade computers. It is actually a pretty power efficient chip, bu…
> The problem was finding funding to pay for the operating expenses, megawatts of power, so it never got off the ground and the hardware has been turned off and decommissioned. Such a bummer. You ran 120,000 graphics card to mine ETH and didn't end up with lambos or like... ether.. to donate to the professor along with the hardware?

If it were based on open ended tooling that anyone interested could experiment freely with, I would feel the same. Unfortunately these giant LLMs are almost the complete opposite of that.
I was just thinking that it would be great to do something like seti@home but for an open libre super LLM: Install a client that would help run / train the huge llm and you get Access to the network to do queries. Kind of how napster/Kazaa were at their time. I would love to work on doing something like that.
Furthermore, how would upgrades work? When new techniques are discovered, it would be hard to upgrade it. We see these challenges already when it comes to major changes in cryptocurrency networks.

Power and cooling were at fixed levels and computers couldn’t really sleep, so cpu cycles were just wasted without seti@home. Nowadays computers idle efficiently, so something like that would make your computer louder and more expensive to run.
I’m probably about median age for HN and when I was looking into folding Seti@home I had no idea and didn’t worry about power cost because it was subsidised by my parents or university. Plus energy was cheaper then. Now as an adult seeing a month of a few GPUs running on the utility bill really hurts.
We've had access to a source of energy that is cheap, zero-carbon and essentially limitless, since the 1950s: nuclear power.

anybody running them would have the same operational costs, probably far higher since miners gravitate to the lowest cost power source

Bitcoin has nothing to do with "cracking SHA256 hashes", for what it's worth. The only thing remotely related is how it brute-forces inputs until it generates hashes that begin with a certain number of bits set to 0.
> hashes that begin with a certain number of bits set to 0. This myth was always intriguing to me. Where does it come from? It's not a number of 0s (which would imply difficulty could only be doubled or halved), it's just finding a hash that is less than the target.

#100It seems the aliens are already here, so not much need for SETI anymore. More seriously though, it appears there was some unresolved difficulty in searching and analyzing the data returned from the network, to the point the scientists working on it gradually threw in the towel and moved on to other projects. https://setiathome.berkeley.edu/forum_thread.php?id=85996 https://einsteinathome.org/content/can-we-run-setiho…
Yeah. They are. https://www.militarytimes.com/off-duty/military-culture/2023... The only time a senior DOD / military official uses the word "possible" is when it's either happened or is going to happen. "It's possible you guys will be deployed within the next year." means "You guys are going to be deployed sometime within the next year."
In fact, the weirdest thing to me about the announcement was that... nobody cared. And yet, this made sense, because...
Wildly speculating, I think there's been a big systematic desensitization program going on due to that being effective against phobias (such as this one, which I'll call "astroxenophobia"): https://www.healthline.com/health/systematic-desensitization
If the announcement made last year was instead made in, say, 1987... actually, no matter how true, no such announcement would have ever been made in 1987 because either the announcer would have had to resign in disgrace or we might have had a good chance for public pandemonium.
