No, if I remember correctly it was somewhere on http://emacswiki.org which is a great resource by the way.

I can recommend CtrlP (or Command-T). I can't imagine navigating in a project without them. They also have great buffer navigation. Personally I mapped <leader>t to CtrlP file search, and <leader>b to CtrlP buffer search (:C

Is rxvt slower? Recently I switched from xterm to rxvt-unicode and it's really great!

undofile sounds great! I didn't know about it. Some people use jj to go to the normal mode. Personally I remapped Caps Lock to Escape in my whole system, so I can go to normal mode easily. You can yank to the system clipboard by providing a

Usually I use a method that I found on some Emacs-related website. It said to use text search for navigating around the file. That's why I use / pretty often. I use f, t, and related movements as arguments to actions.

Personally I have a mapping <leader>x that starts a terminal emulator when running under X or drops to the shell otherwise. When I work on a project I cd into its directory. Executing commands is just a matter of hitting <leader

I would argue that this repetition is not essential . It happens when you assign a constructor argument to an attribute directly without any modification. But there are case where it doesn't appear: - the attribute has a different name

I don't think that nullary constructors are so good. If you have dependencies then after constructing your object it'll be in an invalid state because the dependencies aren't set up correctly.

I remember that Go had some issues related to the garbage collector on 32-bit machines. Are they solved now?

I think that AGPL requires you to give source code to the users of the program. If you use a modified version internally then you'll have to give the source code to your employees. That isn't as problematic as sharing with the whole outsi

I haven't used R nor Pandas. How does the two compare? Why do people use R and not Python?

Wouldn't it be better to have a Python statistics library instead of creating a new language? When I looked at the documentation of R it looked very convoluted and it seems that my feeling is confirmed by other comments in this thread.

At the company I work at we decided against IRC because of possible difficulties for non-technical employees. Currently we're using XMPP but we're considering other solutions.

Please also note that t.send(:attr=, 5) returns 10. When you do t.attr = x Ruby sends :attr= with x as the argument to t and then ignores the return value of the message and returns x instead.

It's related to the right-associativity of the assignment operator and its expected semantics. If you write a = b = c then it is interpreted as a = (b = c) When c = 5 then you expect that a = b = 5 # which is equival

Comments are useful when they provide information that is not in the code (e.g. rationale for the choice of an algorithm, source of a regular expression that parses an URL). Your example HTML encoding function can be coded as: def cle

You could also take a look at http://htwins.net/scale2/ . It's also a very nice demonstration of the scale of the universe from the smallest to the largest objects.
