No, because then you have to trust those other people to not build the package maliciously.

Ah, thanks, makes sense! So it's just a bandwidth-saving device - still, sounds quite useful.

But that SHA hash of the built artifact doesn't go in the package recipe. So how do I know what the SHA hash of the built artifact should be, if all I have is the Guix repo? I can always rebuild the artifacts myself using "challen

The built-in tutorial is, I think, the best way to learn the game. After that, playing with hints mode on (as the tutorial suggests).

Just to be clear, the death clock is hidden and is intended to be impossible to trigger if you're not actively cheesing with one of the very few exploits that depend on waiting for a very long time. IIRC to tune the clock, they took th

There's a built-in tutorial, that's the best way to learn.

Food is far more important in nethack than it ever was in DCSS, it was never a key part of the game in DCSS, just an annoying (and sometimes spoilery) minigame.

Yes, I agree - you had much fewer pre-existing ideas to guide you, and really good new ideas were coming out all the time and you could pick between them - you could do all kinds of innovative things and they would really be novel. Although

Scale isn't everything. If each of 200000 employees used 10 salt packets a week, at a cost of $0.003 per salt packet (from https://www.warehouse115.com/single-serv-flat-salt-packets-p... ), then if they cut their salt e

I believe those are libraries for using these services (e.g., connecting to them and allocating resources inside them), not launching them and setting them up.

I hope Pulumi eventually develops a "bare-metal" mode. I'm very much in favor of using a real programming language to set up systems[0], but I don't like to use cloud services beyond basic hosting. It would be nicer if P

The conceit of this article reminds me of http://ngnghm.github.io/index.html which has the same conceit - examining programming practices in a different universe.

The server side license stuff doesn't prevent shared hosting providers from using software. It just requires hosting providers to open source their infrastructure. I think the internet would be even better today, if shared hosting prov

Yes... the comment above is describing a way to evade such laws, used by food trucks. But I've never seen such that workaround in action, hence my question.

Where are food trucks with touch screen terminals common? I've never seen one in NYC.

nix-env (including nix-env -u) is purely a user-facing UI helper for new users. One would never use it in production, or even for development, even when it was first released; it's only ever been for new user onboarding. So it's a

My favorite dired feature is that if you C-x C-q (the standard Emacs binding to toggle the read-only status of a file), it makes the directory buffer writable. You can then edit the buffer like a regular file, including changing file names

I've wondered the same thing! In particular, the highly polished and powerful interfaces of some roguelikes (DCSS comes to mind) strongly remind me of Emacs. It seems like the scriptability and power of Emacs interfaces is a natural fi

Hm, I've been searching for a good replacement for Google Play Music, and this looks like a compelling option - the library of youtube, the recommendations of last.fm, and the UI of Emacs - an excellent set of ingredients!
