Best way to install MongoDB in Ubuntu

Refer to http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/.

That's the best way.

If you try to install only thru apt-get, you can get a deprecated version.

If you try by downloading the binaries, it won't install useful things like user and service.

How to change the default mode for php files in Kate Editor

Whenever I open a PHP file within the excellent Kate Editor (which I prefer due to its multi-document interface), the default mode for editing the file is PHP (HTML) instead of PHP/PHP. I use much more the indentation of the last one. I always can change the mode thru Tools -> Mode -> Scripts -> PHP/PHP, but it's a pain to do it every time I open a PHP file.

But you can set the default mode to PHP/PHP by changing its priority compared to PHP (HTML)'s.

That's how I did it:

• Go to Settings -> Configure Kate -> Open/Save -> Modes & Filetypes;
• Select Scripts/PHP (HTML) Filetype;
• Change Priority to 4;
• Select the File Extensions field and copy it;
• Select Scripts/PHP/PHP Filetype;
• Go to the File Extensions and paste the content copied;
• Hit Apply and Ok;
• Close and reopen Kate.

I was hard to find that solution (see reference); I hope this can be useful.
