I'd love to read citations for this; this is a topic of interest to me. I ran barefoot for several years (on pavement and grass; stopped because occasional thorn or glass became too obnoxious) and read various peer-reviewed running inj

Maybe? Wood is useful even though there are things that will eat it under the right conditions.

I love Nix and NixOS personally... but it's been a tough sell at work, unfortunately. Even with simple shell scripts... it's so easy to invoke programs with GNU extensions and later find they fail on a co-workers macos machine. An

It's possible to run at or near an elite level without modern running shoes. For example the 1960 Olympic marathon was won by a barefoot competitor (his winning time of 2:15:16.2 would be considered sub-elite today) [1]. One can specul

I wouldn't disagree that snobbishness is present in the running community, but there are standards that must hold for a course to be "record-eligible" (by the dominant athletic organizations). In sprints on a track, this incl

There are two distinct features: immutability and single-assignment. Erlang is famous for single-assignment, and also happens to have largely immutable values, but they are not the same thing. Immutability prevents things like in-place appe

I may be in the minority, but I like the Nix language. I don't have extensive ML or Haskell experience, coming from Ruby/Java background. I think the Nix language works great as a configuration language, and I greatly prefer it to

Many comments seem to only compare systemd with SysV init. But there is a whole world of process supervisors out there, particularly in the daemontools[1] family. systemd is a process supervisor plus additional features; sysv init is not a

See also s6-sudo [1]. It uses Unix domain sockets to pass the users stdin, stdout to a service that runs a program as root. Still has the problem catern points out. [1] http://skarnet.org/software/s6/s6-sudo.html

Just guessing, but maybe a reference to Neal Stephenson's novel, _The Diamond Age_. If I recall, "vicky" is a slightly derogatory term used to describe (wealthy) residents of New Victoria, who are shown to buy things like han

"I can add, remove, test, screw up, change my mind, whatever without stress" I love Nix and completely agree with that, and I do have lots of experience with several package managers (deb, rpm, rubygems, ...)

For unix processes, exit status zero is conventionally considered success and non-zero is failure.

As a daemontools fan, I'm frustrated that something in the daemontools family never became popular (process supervision, be it daemontools, upstart, systemd, etc. makes managing services so much nicer). But I do recognize the utility o

I appreciate your presentation of an alternate viewpoint. The "build from source" camp provides solutions to a couple problems that at first glance seem to be difficult in a "principled mutation of binary image" model: -

The pre-built binary packages available from the Nix project are all compiled for /nix; this choice is baked in to the binaries, which refer to shared libs via absolute paths for example. I understand this path is configurable, but you

The amd64 Linux version of Terraform [1] unzipped uses 739 Megabytes on disk (`du -hc`). It is a collection of CLI tools, or one CLI tool that wraps many provider-specific tools (providers such as aws, azure, etc.). I noticed this recently

Just a guess, but maybe wtbob is getting at the fact that odd licenses are generally GPL-incompatible or otherwise awkward or ambiguous. See for example, the JSLint license https://en.wikipedia.org/wiki/JSLint#License

Can you summarize one or two of Boisjoly's main points? Tufte's pictures of the (superfluous) rocket graphics showing the temperature vs. his redrawing, placing temperature on the x-axis are very convincing.

I'm curious how this handles changes within nixpkgs itself. For example, if developer A has nixpkgs version 111, and developer B has nixpkgs version 222, and they both attempt to build a Haskell project depending on "libxml",

I don't know the state of Python packaging in Nix [1], but it can almost do what you ask. I've used it to create a tarball of, for example, a customized Postgres (built with MySQL foreign data wrapper in this case), and all its de
