Emacs, how to auto turn on flyspell for LaTeX file - emacs

I use Emacs only for \LaTeX and python programming. Is there a way to automatically turn on flyspell-mode when I work on a .tex file, and turn on flyspell-prog-mode when I work on a .py file? How can I do this in my .emacs file?

Add those functions to hooks of python-mode and latex-mode
(require 'python)
;; If you use tex-mode
(require 'tex-mode)`
(add-hook 'latex-mode-hook 'flyspell-mode)
;; If you use AUCTeX
(load "auctex.el" nil t t)`
(add-hook 'LaTeX-mode-hook 'flyspell-mode)
(add-hook 'python-mode-hook 'flyspell-prog-mode)

Something like this should work.
(setq auto-mode-alist (cons '("\\.tex\\'" . flyspell-mode) auto-mode-alist))
(setq auto-mode-alist (cons '("\\.py\\'" . flyspell-prog-mode) auto-mode-alist))

Set Flycheck enable for other mode

Currently, my emacs's flycheck is enabled for js as default. I'm using global-flycheck-mode but not sure if I have set its value as a list. I wonder how to enable flycheck for other modes like json-mode, web-mode, c++mode. Here is my settings for flycheck.
;; ===================flycheck settings start====================
;; use web-mode for .jsx files
(add-to-list 'auto-mode-alist '("\\.jsx$" . web-mode))
;; http://www.flycheck.org/manual/latest/index.html
(require 'flycheck)
;; turn on flychecking globally
(add-hook 'after-init-hook #'global-flycheck-mode)
;; disable jshint since we prefer eslint checking
(setq-default flycheck-disabled-checkers
(append flycheck-disabled-checkers
'(javascript-jshint)))
;; use eslint with web-mode for jsx files
(flycheck-add-mode 'javascript-eslint 'web-mode)
;; customize flycheck temp file prefix
(setq-default flycheck-temp-prefix ".flycheck")
;; disable json-jsonlist checking for json files
(setq-default flycheck-disabled-checkers
(append flycheck-disabled-checkers
'(json-jsonlist)))
;; https://github.com/purcell/exec-path-from-shell
;; only need exec-path-from-shell on OSX
;; this hopefully sets up path and other vars better

(exec-path-from-shell-initialize))

(let ((web-mode-enable-part-face nil))

ad-do-it))
;; c++
(add-hook 'c++-mode-hook (lambda () (setq flycheck-gcc-language-standard "c++11")))
;; ===================flycheck settings end======================
Im currently using this one. Works fine.
;; Enable for other modes
(add-hook 'c++-mode-hook 'flycheck-mode)
(add-hook 'web-mode-hook 'flycheck-mode)
(add-hook 'json-mode-hook 'flycheck-mode)
But I still don't understand why it only enables for js2-mode before.

Emacs does not see new installation of Org-Mode

I had installed org-mode version 8.2.1 from emacs list-packages.
I downloaded the latest version 8.2.4 and placed it in .emacs.d and added the following to my .emacs,
(add-to-list 'load-path "~/.emacs.d/org-8.2.4/lisp")
Emacs still reports org-mode version to be 8.2.1
Try removing old installation(s) of org-mode from the load-path first:
(require 'cl)
;; Org-mode that was shipped with Emacs
(setq load-path (remove-if (lambda (x) (string-match-p "org$" x)) load-path))
;; ELPA
(setq load-path (remove-if (lambda (x) (string-match-p "org-20" x)) load-path))
(setq custom-org-path "~/.emacs.d/org-8.2.4/lisp")
(add-to-list 'load-path custom-org-path)
Also make sure to do it as early as possible in your init.el - especially if you use org-mode-based system for your emacs configuration files.
Add the following to your init.el file.
(require 'package)
(add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/") t)

emacs auto-complete don't work with jde

I want to develop java in emacs. I install ecb, jde and auto-complete extensions. Each one works well without starting others. But when i want to use them together, some problem happened.
auto-complete-mode doesn't auto start with jde, I need to start it by M-x auto-complete-mode. If without jde, auto-complete-mode will auto start
When I manually start the auto-complete-mode in jde, the auto complete is not work well. It just auto complete the word that is appeared.
Here is my .emacs content:
(global-linum-mode 1)
(setq linum-format "%2d| ")
(setq default-tab-width 4)
(setq debug-on-error t)
;;no backup file
(setq make-backup-files nil)
(setq debug-on-error t)

(ac-config-default)
(setq stack-trace-on-error t)

The version info is :
emacs : 24.1
auto complete : 1.3.1
ecb : 2.40
cedet : 1.1
elib : 1.0
jdee : 2.4.0.1
To auto-start auto-complete-mode with jde-mode, you need to add jde-mode to ac-modes:
(push 'jde-mode ac-modes)
Then you need to add a JDEE-specific source to ac-sources. I'm not sure of the extent of JDEE integration with Semantic, you may be able to use the pre-defined source for it:
(add-hook 'jde-mode-hook (lambda () (push 'ac-source-semantic ac-sources)))
If not, you may need to define a specialized source with ac-define-source. See auto-complete-config.el for examples.

flyspell doesn't load with LaTeX file in emacs

Following this web page, I have edited my ~/.emacs file and added the line:
(add-hook 'LaTeX-mode-hook 'flyspell-mode)
However, flyspell doesn't start with LaTeX files. Why is that so?
I could not make this work:
(add-hook 'LaTeX-mode-hook 'flyspell-mode) or
(add-hook 'latex-mode-hook 'flyspell-mode)
But then I found this:
(add-hook 'LaTeX-mode-hook 'turn-on-flyspell)
-and it is working.
Emacs is case-sensitive; the hook should be written as latex-mode-hook. Try this:
(add-hook 'latex-mode-hook 'flyspell-mode)

Emacs auto-complete-mode at startup

I just install auto-complete-mode, however everytime I start emacs I have to M-x auto-complete-mode. Is there anyway to have it loaded automatically ?
My .emacs is as follows:
;; auto-complete
(add-to-list 'load-path "~/.emacs.d/")
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "~/.emacs.d//ac-dict")
(ac-config-default)
Thanks
I think you can do it in various ways. To enable it globally you should use
(global-auto-complete-mode t)
But it uses auto-complete-mode-maybe, which turn AC on only those listed in ac-modes. You can add them manually just like this
(add-to-list 'ac-modes 'sql-mode)
You can make your own list if you wish AC be active only for few modes
(setq ac-modes '(c++-mode sql-mode))
Or rewrite it to have AC everywhere.
(defun auto-complete-mode-maybe ()
"No maybe for you. Only AC!"
(auto-complete-mode 1))
edited:
Autocomplete in minibuffer is bad. I think this will be better.
(defun auto-complete-mode-maybe ()
"No maybe for you. Only AC!"
(unless (minibufferp (current-buffer))
(auto-complete-mode 1)))
I just needed this:
(require 'auto-complete)
(global-auto-complete-mode t)
added to my .emacs.d/init.el file.
I installed auto-complete with the package manager. I'm using Emacs 24.
