General notes

• nix-channel and ~/.nix-defexpr are gone. We'll use $NIX_PATH (or user environment specific overrides configured via nix set-path) to look up packages. Since $NIX_PATH supports URLs nowadays, this removes the need for channels: you can just set $NIX_PATH to e.g. https://nixos.org/channels/nixos-15.09/nixexprs.tar.xz and stay up to date automatically.

• By default, packages are selected by attribute name, rather than the name attribute. Thus nix install hello is basically equivalent to nix-env -iA hello. The attribute name is recorded in the user environment manifest and used in upgrades. Thus (at least by default) hello won't be upgraded to helloVariant.

  @vcunat suggested making this an arbitrary Nix expression rather than an attrpath, e.g. firefox.override { enableFoo = true; }. However, such an expression would not have a key in the user environment, unlike an attrpath. Better to require an explicit flag for this.

TBD: How to deal with search path clashes.

nix-shell and Shebang Lines

A few days ago, version 1.9 of the Nix package manager was released. From the release notes:

nix-shell can now be used as a #!-interpreter. This allows you to write scripts that dynamically fetch their own dependencies.

The Scammiest Scam To Yet Anonymity Scam

I'm still holding out for this being a hoax, a big joke, and that they're going to cancel the kickstarter any minute. It'd be quite the cute "lessons learned" about anonymity scams. However, I will be treating it from here on out as a genuine scam. (As of May 2nd, the kickstarter has been cancelled, after the strangest attempt to reply to this imaginable. Good riddance.)

This absolutely ridiculous thing was brought to my attention by a friend and since it was late at night I thought I must be delirious in how absurdly over the top fake it seemed. So I slept on it, woke up, and found that it had gotten a thousand dollars more funding and was every bit as flabbergasting as I thought it was.

Since I realize that not everyone has spent their entire lives studying computers – and such people are the targets of such scams –
