The built-in Dired is launched when I type C-x d. dired+ is loaded because I can run diredp-* commands, but dired+ is only launched after I have run a diredp command. What is the problem? I am using Emacs 24.1 and I installed dired+ through the package manager.
Dired+ is not loaded. All the functions you see are autoloaded. This means that as soon as you call one of those functions emacs knows it needs to read diredp.el. Once it reads that file, it overrides the default dired and makes everything work.
To fix your problem, just (require 'diredp) in your .emacs.

I'm using emacs -nw (Emacs 24.5, Ubuntu 16.04). And I found that the default emacs M-w C-y keys don't work interchangeably with the operating system.
After some research, it seems that the most comprehensive solution is to use simpleclip. EmacsWiki says that
simpleclip
You can use https://github.com/rolandwalker/simpleclip which ALWAYS
works.
But looking into its usage guide above, simpleclip makes use of a set of keys that are completely different from the default M-w C-y or the OS Ctrl-Shift-c, Ctrl-Shift-v for copy-paste
;; Press super-c to copy without affecting the kill ring.
;; Press super-x or super-v to cut or paste.
I don't really want to use super key a lot with my PC keyboards, and don't want to remember (or persuade others to remember) yet another set of copy-paste keys.
For the GUI emacs, I can copy something in emacs and paste it into another terminal without any configuration. Mostly, I don't feel that Emacs is any different from gedit except that the emacs copy-paste keys M-w C-y can be used in addition.
In the terminal mode, most of it breaks down. If I use OS copy (Ctrl-Shift-c), one line in emacs can be copied into two or more lines in a target terminal because the line is too long. contents copied using M-w simply do not paste into other programs, even though I tried to set certain variables following other SO questions, e.g.:
(setq x-select-enable-clipboard t)
I'm not very familiar with elisp. My question:
How can I customize or configure simpleclip so that copy-paste in emacs -nw is exactly the same as copy-paste in the OS?

I recommend you use the xclip package, which you can install from GNU ELPA (i.e. via M-x package-list-packages). It requires installation of the xclip utility under X11 (e.g. via aptitude install xclip) and uses the pbcopy/pbpaste under macOS.
So I've installed ELPA, and did the command M-x package-install RET auctex.
I was prompted with the message that 133 files were compiled and one was skipped.
But I cannot find auctex mode anywhere when trying to initialize it with M-x auctex-mode.
Am I missing something?
AUCTeX is a package that includes multiple TeX and LaTeX modes, but does not define an explicit AUCTeX mode. To invoke a mode explicitly, use M-x TeX-<TAB> or M-x LaTeX-<TAB> to see the possibilities.
Assuming that the package is installed correctly, these tab-completions should resolve.
Various of the modes may be started automatically upon opening files with certain extensions, perhaps like myfile.tex or similar.
I used to launch latex within Emacs on a .tex file by C-c C-c.
I just changed my machine, and need to reconfigure all. I have already installed texlive-full, and copied .emacs from the previous machine to the new machine.
When I open a .tex file under Emacs, launch C-c C-c, and then type LaTeX, it opens another buffer, named *tex-shell*, and looks like as so:
Could anyone tell me what happened?
I don't really now what happen, but it seem you want to use auctex:
sudo apt-get install auctex
and relaunch Emacs should solve your problem.
I'm using some plugins and I byte-compiled my .emacs but the start up still slow. Do I hava to byte-compile my prlugins too? (for instance, yasnippet.el -> yasnippet.elc)?
Byte compiled files load up faster so I'd recommend that you byte compile everything as Pascal suggested. I also keep this in my init file so automatically byte compile all the emacs lisp files I edit and save.
(add-hook 'emacs-lisp-mode-hook '(lambda ()
(add-hook 'after-save-hook 'emacs-lisp-byte-compile t t))) ;; Automatically byte-compile emacs-lisp files upon save
Emacs can feel slow to start up even without any .emacs or plugins :)
It is a good idea to compile plug-ins, that's as much time shaved from start-up. Compiling the .emacs configuration file is less usual (because it changes more often and is typically small anyway), but why not?
You probably already know this, but .el files can be byte-compiled using: M-x byte-compile-file or M-x byte-recompile-directory .
You can use emacs server to speed things up, then it only takes time to start the server the first time.
The way to start an Emacs server is to run Emacs as a daemon, using the ‘--daemon’ command-line option. When Emacs is started this way, it calls server-start after initialization, and returns control to the calling terminal instead of opening an initial frame; it then waits in the background, listening for edit requests.
Once an Emacs server is set up, you can use a shell command called emacsclient to connect to the existing Emacs process and tell it to visit a file. If you set the EDITOR environment variable to ‘emacsclient’, programs such as mail will use the existing Emacs process for editing.

A great selection of tips for automatically byte-compiling files, when you save them or when you load them, and even caching the compiled files in a certain directory.
I have decided to check out Emacs, and I liked it very much. Now, I'm using the Emacs Starter Kit, which sort of provides better defaults and some nice customizations to default install of Emacs.
I have customized it a little, added some stuff like yasnippet, color-themes, unbound, and other stuff. I've set up a github repository where I keep all of the customizations so I can access them from multiple places or in case something goes bad and I lose my .emacs.d directory.
All of this is very nice, but there is a problem: Emacs takes about 1-2 seconds to load. AFAIK I can compile individual .el files with M-x byte-compile-file to .elc, and it works. But there are a lot of .el files, and I wonder if there is a way to compile them all with a simple command or something, to speed up the loading of Emacs. My Emacs is not always open, and I open and close it quite frequently, especially after I've set it up as a default editor for edit command in Total Commander to get used to it faster (yeah, windows xp here).
My Emacs version is 22.3. And yes, the default Emacs installation without any customizations fires up instantly.
I am not sure which version is preferred when loading, the .el or compiled .elc one by the way O.o
So, is there an elisp command or Emacs command line switch to make Emacs byte-compile everything in .emacs.d directory?
C-u 0 M-x byte-recompile-directory
will compile all the .el files in the directory and in all subdirectories below.
The C-u 0 part is to make it not ask about every .el file that does not have a .elc counterpart.
To automatically byte compile everything that needs byte compiling each time I start emacs, I put the following after my changes to load-path at the top of my .emacs file:
(byte-recompile-directory (expand-file-name "~/.emacs.d") 0)
Surprisingly, it doesn't add much to my startup time (unless something needs to be compiled).
To speed up my emacs, I first identified the slow parts using profile-dotemacs.el and then replaced them with autoloads.
You can use the --batch flag to recompile from the command line.
To recompile all, do
emacs --batch --eval '(byte-recompile-directory "~/.emacs.d")'
or to recompile a single file as from a Makefile,
emacs --batch --eval '(byte-compile-file "your-elisp-file.el")'
This is swaying a bit from the question, but to solve the problem of loading slowly you can use the new daemon feature in Emacs 23.
"If you have a lot of support packages,
emacs startup can be a bit slow.
However, emacs 23 brings emacs
--daemon, which enables you to start emacs in the background (for example
when you log in). You can instantly
pop up new emacs windows (frames) with
emacsclient. Of course, you could
already have an emacs 'server' in
older versions, but being able to
start it in the background makes this
a much nicer solution"

The command I use is M-x byte-force-recompile RET, it then asks the directory so, for example, I give it ~/.emacs.d/elpa/. It then recompiles everything in there, usually no need to delete .elc files first or mess with it in other ways.
For my using spacemacs, the command is spacemacs/recompile-elpa. The command byte-recompile-directory does not compile any file.
