Right, because it scratches some nostalgia thing that people have obtained osmotically. Nobody actually wants a replaceable battery that makes their phone vastly thicker and harder to waterproof, nobody wants phones that randomly catch fire

That’s because its weird and mostly irrelevant, it’s nothing to do with the proof of work being any sort of economic impediment. It takes Claude a few minutes to write a near instant solver, that’s the maximum proof of work cost this adds.

It’s not seconds though, it’s in the order of tens of milliseconds of work, it’s faster to complete the challenge than most http requests will take. last difficulty 5 nonce 645376 in 9 ms (101.6MH/s, avx512-x16) This takes many

Most devices never test their memory and don’t have ecc, so you generally never know. Random instability can be fixed by restarting and your program not being in an area with bad bits anymore.

People tried this in 2013 or so, there's no point to it. Doing proof of work in javascript in a browser is so crushingly, pointlessly slow that there's no value at all. Some browsers also intentionally detect attempts to do proof

The prompt used for Opus 4.8 was: write a implementation of the anubis proof of work in native c code, optimized for speed above all else. use every trick available to make the proof of work as efficient and fast as possible, includin

It's more or less designed for it, it's SHA256 with a break in the middle for midstate compression to be effective, and the difficulty system is based on a misunderstanding of how bitcoin PoW works ("number of zeros" is

Which is trivially bypassed by an actual implementation of the proof of work in non-javascript, rendering it absolutely useless. The website is approximately 3800x times slower than native code, and hundreds of thousands of times slower tha

The barrier is a two sentence prompt to Claude to add a patch to curl that does 500MH/s to the 50kh/s the javascript version does on the same hardware, it only works because it’s obscure and largely irrelevant.

Then the only people who can use it are the ones with a GPU implementation.

Claude Opus can make an optimized version of the proof of work solver that’s more than 10000x faster than the javascript one, in about 5 minutes time. Who is this stopping exactly? It’s the wrong tool in the wrong place.

Very little uses crystal oscillators, they’re gigantic compared with electronics today and have very wonky performance over temperature and shock.

That's why this is just using off the shelf cartridges with commercial heads.

1 petabyte per 60 second scans implies a kind of comical data rate to storage, even at RAM speeds that’s implausible. Imagine we need to write these to hard drives, they happily sustain 150Mb/s on the high end, which would imply you’d

xray, photomultiplier and laser tubes are still SOTA. PM tubes in particular have a huge number of glass feed through for the intermediate plate voltages.

The idea that you could buy any food that doesn’t fit that definition is silly, all foods have additives that’s why you can buy them and they last for more than 60 seconds on a shelf, all foods are processed because we don’t eat raw seeds a

It’s basically a wildcard, “ultra processed food” is a classification of nothing and everything. There’s nothing inherently bad about processing food, lots of food is terrible for you but that’s unrelated entirely.

There's actually a known prototype MacBook Pro from 2006 with a cellphone radio, and the release MacBook Pros from the time all have a weird looking area near the battery and RAM where the SIM slot was supposed to be, and some leftover

I had a thinkpad at one point that had a slot, but because it wasn't optioned for it you had to patch the BIOS or it wouldn't boot with anything in the slot, it seemed so hostile as to be worthless.

I somehow managed to get it working in 2016 with a lot of hackery, I'd still have it as a usable device if the weird little pouch cells it had didn't die, repacking those batteries seemed like enough of a fire hazard I just didn&#

The cause is just that the panel is mounted rotated on the device. It's supposed to be used in a tablet where the top is the short end and the side is the long end, opposite to a laptop.

I miss my Sony Vaio P series which fitted in a similar sort of niche, the cellphone radio made it just by far the best laptop I've ever used. Modern laptops don't seem to have provision for a LTE/5G radio which always confuse

They’re used for proofs sometimes, if you expect your security company to do a specific route they need to go to each token on it and touch them, you see iButtons glued to walls outside commercial buildings for that purpose. Systems like th

Proof of work doesn’t work here same as it doesn’t work for email. The effort to mint a valid PoW is always going to put the legitimate user at a disadvantage, whatever the implementation is. Someone with an incentive to spam will always be

The whole website is AI slop, from the text down to the design. If it's an actual product who knows, sort of hard to care when the website came from a Claude prompt.
