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.

I wrote this four years ago, so instead use this command:

$ docker rmi $(docker images -q -f dangling=true)

Last active Dec 1, 2018
This Rack middleware for Rails3 lets you see a call-trace of the lines of ruby code in your application invoked during a single request. Only code within your app is considered (i.e. in the /app folder). This expands on my previous attempt (https://gist.github.com/3077744). Example of output in comments below.
View rails_trace.rb
require 'singleton'
# outputs a colored call-trace graph to the Rails logger of the lines of ruby code
# invoked during a single request.
#
# Example:
#
# 1) Make sure this file is loaded in an initializer
#
# 2) Add the following to your application.rb in Rails3:

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
