Emacs packages, features, files, layers, extensions, auto-loading, require

, use-package
… All these terms getting you confused? Let’s clear up
a few things.
Emacs files contains code that can be evaluated. When evaluated, the functions, macros and modes defined in that file become available to the current Emacs session. Henceforth, this will be termed as loading a file.
One major problem is to ensure that all the correct files are loaded, and in the
With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

DrainStop Attempts to gracefully shutdown an endpoint when a normal shutdown | |
occurs. It first shuts down the acceptor, ensuring that no new requests can be | |
made. It then waits for all pending requests to complete. If the timeout | |
expires before this happens, it stops waiting, allowing the supervision tree | |
to continue its shutdown order. |

Jim Weirich:
This is how I explain it… Ruby has Procs and Lambdas. Procs are created with
Proc.new { }
, lambdas are created withlambda {}
and->() {}
.
In Ruby 1.8,
proc {}
creates lambda, and Ruby 1.9 it creates procs (don't ask).
Lambdas use method semantics when handling parameters, procs use assignment semantics when handling parameters.
This means lambdas, like methods, will raise an ArgumentError when called with fewer arguments than they were defined with. Procs will simply assign nil to variables for arguments that were not passed in.
