Solar panels.
So now you need additional capital expenditure to handle the extra load of running your CPU and GPU 24/7, above your base load.

Chungy is correct though. Bitcoin has absolutely nothing to do with "cracking sha256 hashes". Bitcoin hashes until the correct output is found. There are double hashes, but that is solely to avoid collisions and has nothing to do with determining the plaintext from a known digest.
It's kinda sad. If we persisted all the hashes that have been tried, we'd have the mother of all rainbow tables. Be a bitch to search. But damn would we know the topography of the function space.

>and has nothing to do with determining the plaintext from a known digest. So why'd you bring it up?
User bitcoinistrash is the one that brought it up, and they're spreading incorrect information about how it works. Cracking sha256 hashes implies trying to reverse a specific hash. There are literally thousands (millions?) of potential inputs that hash to a valid bitcoin mining block output. It's basically a race to find the first one matching the rules of the current block difficulty. The goal isn't to produce any o…

I have had around 13 power outages this week. I live right in the middle of Silicon Valley. Most of the charges from PG&E are indeed the grid charges, the rest is supposedly a mandatory green energy. This is depressing.
Fellow SV resident (does Cupertino count?) and my eyes water when I look at my energy bill. Then I lose power for two days and learn that people REALLY dislike PG&E. And I thought National Grid was bad.
While other countries have stable and reliable power in the face of hurricanes and ice storms, our power is routinely knocked out by cars, trees, and basically any act of nature.
I love how expensive everything is for how behind we are from the entire rest of the world. Too bad the expenses keep me trapped and poor, unable to do anything about it—even just move to any other country.

Once the original Bitcoin OG cypherpunks shifted from “here is an amazing new technology that could do entirely new things” to tweeting about the USD price of Bitcoin, I knew that era was over. I think it was done by ~2015. The Ethereum research community is still doing very neat cutting-edge things, but they’re a younger generation and didn’t claim to believe in the same principles (only to later disappoint us all.)
How did the Ethereum research community disappoint us all?

My MacBook Pro with M1 Pro is the first laptop I've had that hasn't had that slight hesitation that laptops have always had. I think this is why people praise Apple Silicon so much even though the benchmark numbers may not always back it up - so many other people are also coming from similarly-hobbled laptops.
I have a great desktop, and every day I curse Apple and Tim Cook because I cannot get an iPad Pro that runs full macOS. That would be the ideal device for me when I'm on the go, that I can still use to watch Youtube videos in the bathroom. I do not need a full laptop when I work at home with a $5,000 desktop PC, nor I want to buy a crappy $300 laptop that always feels slow and underpowered. It is really sad to have t…
Put it behind a VPN, use wake-on-lan and boom, iPad is essentially a fully blown computer.
This 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…
> I've been running >120k gpus to mine ETH So when the sea levels rise and destroy my home, I'll know who to blame. Thank you.
120k gpus is like what USD50mio capex at least? Did you even get any of that back w/o accounting for electricity?
Self-promotion: In particular LODA has my interest. It's a math AI, that uses OEIS as training data. https://boinc.loda-lang.org/loda/
Disclaimer: I'm not the primary developer, but I made some contributions to LODA, such as the web editor for LODA programs: https://github.com/loda-lang/loda-rust
Is it possible to distribute AI training like this so that people could donate their idle processing power to creating a truly open source unencumbered LLM?
Yes. You'd have to package up slices of the training set and the prior epoch as work units and host them. Our hypothetical GPT@home clients download the training set, train just those examples, and then send back their gradients. The server then averages all the gradients together. As far as I can tell this isn't any different conceptually from the distributed inference setup that PyTorch/Huggingface Accelerate/etc s…

I just cant get a laptop i feel comfortable working on, they all have that slow feel, where a desktop is just crisp and i can always just switch out anything i dont like about the current build..

Sorry for the snark. I'm just bitter because Apple is about to ruin Dropbox because they don't allow KEXTs any more.
