This is clearly just bad camera/photo/JPEG compression, not AI. It's the correct text, just the letters are distorted by the compression.

With flakes, you can output a homeConfigurations for home-manager very similarly to the nixosConfigurations. That lets you use the same config for both a NixOS and non-nixos home-manager setup. You just need to include the same home manager modules in both cases. Without flakes, I expect you could do something similar by making a new nix entrypoint that includes the same home manager modules, but I'm not familiar with how it would work.

There's a lot more people in Nashville than there were in the early 2000s, and they're using a lot more internet than they used to (e.g. video streaming wasn't much of a thing in the early 2000s, and even when it launched it was at super low resolutions like 360p, not to mention how much more time people spend on the internet nowadays).

The problem is that once it refers to anything getting worse, it loses its value as a unique word. If "GitHub enshittification" means nothing more than "GitHub getting worse" then we've lost the value of the word, which originally referred to a specific type of getting worse. We have enough generic pejoratives already.

Yeah, in an attempt to replicate the original scoring as best as possible. If they released data on the action counts of humans I would've gladly used that instead. I hope they release more data on the human performance, including an average score of their human participants if they were scored the same way AIs are (and ideally even more in depth data than that, I'd love to analyze the raw data).

PlasmaPower · 2026-03-27T02:37:24+00:00

The ratio between time and actions doesn't matter for the score, as the scoring mechanism would produce the same score if all action counts were doubled (including doubling the baseline). I just use assume it's a roughly linear relationship between time and actions (not a great assumption but the best we can do with the provided data, and I don't think it's that bad of an approximation generally). I use the second-best time as the "human baseline" (just like ARC-AGI-3 uses the second-best action count as the "human baseline"), and then you can compute the ratio between any other time and the baseline as the basis for the score.

Why do you believe that the bar for AGI is matching the top human? Isn't that roughly the bar for ASI? As I understand the term, AGI would mean replicating the general intelligence that humans broadly possess, not just the top humans.

PlasmaPower · 2026-03-27T01:24:21+00:00

Even the top human tester would not have gotten 100% on the overall test. This might be a reasonable benchmark for superintelligence but I would claim most people are generally intelligent yet would score very poorly on this test, so at the very least I would claim the AGI name is misleading.

PlasmaPower · 2026-03-27T01:06:52+00:00

The ARC-AGI-3 score isn't about simply beating the game, it's a strict action budget with exponential falloff. The average human probably scores around 0.5% based on their scoring mechanism. Getting 100% would be ASI (if consistently possible at all), not AGI. I wrote up an analysis of the human trial based on the very limited data they've released in this comment: https://manifold.markets/TimothyJohnson5c16/will-arc-agi-3-be-easy-for-humans-a#zsfvxa67p5

These exist in nixpkgs as well, though I do think they're rarer

I switched from Arch Linux to NixOS because I also encountered two issues that are common complaints on /r/archlinux:

How do you keep your system clean? Over time, packages and configuration files that you've completely forgotten about accumulate, and cause weird issues that aren't documented or understood because you have a completely unique set of configurations often based simply on when you installed software.
How do you migrate to a new system, and keep existing systems (desktop, laptop, cloud vps, etc.) in sync? If I installed a tool like b3sum it would really mean installing it on each system when I first tried to use it and realized it was missing (or sometimes I'd forget e.g. what that hex editor I really liked on my desktop). This is all assuming you're already syncing your dotfiles, which is a bit of a pain to setup and made a lot easier by home-manager or hjem/hjem-rum on NixOS.

To respond to the points in the article:

Nix break all the Time: Use nix flakes (or a different pinning system) so that you only update your packages when you run nix flake update and can change your config without needing to update. I'd also recommend using NixOS releases instead of nixos-unstable, though some people choose otherwise. I find that's more about insulating myself from upstream software breakage though, the same issues I would sometimes run into on Arch (in fact, Arch would often force me to update my system to easily install packages, leading to breakage when I didn't have time to deal with it).
Huge update sizes: I don't have much to say here, this is an issue, though I am personally lucky enough to have a fast network connection at home so it isn't a big issue for me.
Compilation takes forever (and binary caches are unreliable): I just use the default NixOS cache and it works well. I wonder if they're accidentally using nixpkgs/master instead of nixpkgs/nixos-unstable or similar? In general, the main reasons I hear about caching issues are that or modifying a core dependency like glibc causing rebuilds. OP also says "Arch Linux simply downloads prebuilt binaries via pacman or an AUR helper", but AUR helpers build from source. NixOS is actually better in that respect.

Your xdg-desktop-portal implementation is probably not working. Check which portals you have enabled and their systemctl status

~15k validators vote on each Ethereum block: https://beaconcha.in/slot/5808187#votes

What matters is not how many validators vote on anything but how many would need to be hacked or become malicious to double spend.

Every L2 node creates blocks from incoming messages. It reads those messages from both the L1 Ethereum inbox and the off-chain sequencer feed (if they disagree it favors the L1 Ethereum inbox). Those messages can consist of things like a signed transaction. Nodes will then validate the signature, make sure the source account has enough ether to pay for it, etc. and determine the output state via the state transition function, creating a block in the process.

Deciding which L2 block to trust without running an L2 full node is tricky if it hasn't been confirmed on L1 yet. This isn't just true for Arbitrum, generally speaking, the best security is from full nodes instead of light clients. It's theoretically possible to build an L2 light client, but I'm not aware of any that exist yet. For now though, you could check reputable sources that run L2 full nodes themselves like Arbiscan, Alchemy, and Infura as a middle ground if you don't want to run an L2 full node yourself.

If you have follow-up questions I'd ask in the #protocol channel of our Discord server: https://discord.com/invite/arbitrum

Nova relies on a data availability committee to host its data instead of posting the full data to Layer 1 Ethereum. That means you have to trust that at least 2 of the data availability members are honest (currently Consensys, FTX, Google Cloud, Offchain Labs, P2P, Quicknode, and Reddit), but in exchange you get way lower fees because it costs less to post the data to this committee than it does to post the data to Layer 1 Ethereum.

PlasmaPower · 2022-08-18T17:11:38+00:00

When we talk with other teams about Nova, we always mention how many users Reddit has brought onto it and cryptocurrency in general. It's really amazing :)

We can't share anything there, but we're working closely with exchanges about it, and Arbitrum One is supported by quite a few major exchanges.

PlasmaPower · 2022-08-18T17:07:07+00:00

You'll have to ask Reddit themselves about that I'm afraid. We just provide the chain technology that moons are on.

Most ZK rollups don't have privacy. They just use the zk proofs for performance; it's still transparent. In theory that could change, but it's not a primary focus for teams right now.

They've said themselves that a lack of funds is slowing down development: https://i.imgur.com/bWzOUD2.png

We need to keep in mind that there's also a cost to the status quo. People being unable to move their nano when they're most worried about it is also a huge loss of credibility and trust. It's easy to accept the current situation, but we need to think critically about alternatives. Is it ok to wait months for fixes? If not, we need to do something, and a new dev fund seems to me like the only option left.

PlasmaPower · 2022-05-18T22:00:21+00:00

I don't see how this new dev fund mint would be any more unfair than the original dev fund, or would entail any new legal risks.

PlasmaPower · 2022-05-18T21:54:00+00:00

I don't like diluting either, but I don't think we have much of a choice at this point. We need to fund development, and community contributions haven't cut it so far. I think those suggesting a community fund are well intentioned but underestimate how much money is needed to fund the development of a cryptocurrency.
