As of Emacs 24.3, an analog of the old multi: syntax has been layered on top of the modern tramp-default-proxies-alist approach, meaning that you can once again perform multi-hops without any prior configuration. For details, see: C-hig (tramp)Ad-hoc multi-hops RET With the new syntax, each ‘hop’ is separated by |. The example in the manual … Read more
Update: Emacs 24.3 has been released with full support for this new setting! In the current trunk of emacs, you can simply customize the variable create-lockfiles: C-h v create-lockfiles Documentation: Non-nil means use lockfiles to avoid editing collisions. In your init file, you can set (setq create-lockfiles nil) Get it via bzr branch bzr://bzr.savannah.gnu.org/emacs/trunk emacs-trunk … Read more
You have a couple of options, one of which doesn’t require you to know where the file is; however in due course you’re almost certainly going to want to make changes to the file, so let’s start there. First, where is my .emacs file and what is it? You also have some options for the … Read more
If you’ve ever been saved by an Emacs backup file, you probably want more of them, not less of them. It is annoying that they go in the same directory as the file you’re editing, but that is easy to change. You can make all backup files go into a directory by putting something like … Read more
Copy and pasted from the Emacs FAQ, http://www.gnu.org/software/emacs/windows/: Where do I put my init file? On Windows, the .emacs file may be called _emacs for backward compatibility with DOS and FAT filesystems where filenames could not start with a dot. Some users prefer to continue using such a name, because Windows Explorer cannot create a file … Read more

In short, most terminal emulators are limited in the control characters they can produce (for the simple reason that the original terminals that they are emulating were likewise limited). So your terminal is very likely not producing anything other than . when you press C-. (and if that’s the case, that’s basically your answer, unless … Read more
The Bad test-a is self-modifying code. This is extremely dangerous. While the variable x disappears at the end of the let form, its initial value persists in the function object, and that is the value you are modifying. Remember that in Lisp a function is a first class object, which can be passed around (just … Read more
It really depends on what language you’re using, but in C# and Java I find IDEs beneficial for: Quickly navigating to a type without needing to worry about namespace, project etc Navigating to members by treating them as hyperlinks Autocompletion when you can’t remember the names of all members by heart Automatic code generation Refactoring … Read more
It’s worth noting why Emacs defers the package initialization: See C-hig (emacs) Package Installation RET, and in particular: The reason automatic package loading occurs after loading the init file is that user options only receive their customized values after loading the init file, including user options which affect the packaging system. In some circumstances, you … Read more
