I just got a T480 thinkpad from craigslist for 120$. Frickin stellar machine for the money. Its not the fastest, but fine for light dev. Or will be once I put 32G of ram in it. With 16 I sometimes experience slowdowns due to swap. Luckily memory isn't soldered in on this model.
No touchscreen though, and I wouldn't get one even if it was available. Paid extra for that in my old precision 5520, and almost never used it. If it doesn't fold completely then its not useful IMO.
Speaking of which, my dell precision 5520 was a good machine, but had chassis problems. Hinge fell apart after screws fell out, and as a result the power connector broke, as did a replacement power connector. Dell battery swelled up making the touchpad unusable, so did a replacement dell battery. No-name lower capacity battery ok. Keyboard wore out and keys cracked, replaced but now becoming unreliable again. Screen and motherboard are still good, but unfortunately its become unusable. Some of these problems are to be expected in a 7 year old heavily used laptop, but I haven't seen this same degree of decay in thinkpads.
This specific tech is, yes, nvidia dependent. The game changer is that a team was able to beat the big players with less than 10 million dollars. They did it by operating at a low level of nvidia's stack, practically machine code. What this team has done, another could do. Building for AMD GPU ISA would be tough but not impossible.
Some assholes gave congresscritters a bunch of money to get their businesses a cozy monopoly and special treatment. They were seeing AI as a profit center they could corner the market on thanks to govt-industry collusion. Looks like ginormous data centers and export controlled GPU cards may not be as essential to AI research as thought, and now the emergency is their stock is tanking.
Ok that's pretty close! The reddit thing was about streaming your camera, and having a chat window where you could read comments from viewers.
The other key element was having a place where viewers could see what was currently streaming. That allows people to casually go see "what's on" without needing to coordinate with livestreamers to set up a time to watch, keep track of streamer channels, etc.
I really liked the livestream feature that was on reddit a few years ago. Would be cool to have a fediverse version of that, where people could casually stream from their phones with just a peertube app.
Packages in nix are in the store directory, each package in a dir named after the package hash. So you can have 15 versions of firefox installed, for instance, and the different versions go in different folders with different hashnames.
When it's time to set up a user env, their specific version of firefox is (conceptually) symlinked into the users profile. When that user executes firefox it gets one out of the 15 versions. Another user may get a different one.
Anyway, the package store is off limits to users, and a real bad idea to modify for root too.
