Free Programs That Do Cool Things

some of them dont work with a MAC what can i do?

MediaCoder is pretty good for converting media files, and they have a cuda version, so if you own an nvidia card with cuda, it's gonna be blazing fast.

linux backtrack
linux OS used for penetration testing or we might as well call it hacking.. :D :D

Notepad2 (it replaces your Windows Notepad =P)
Tunngle (special VPN por gamers)
Comix (comic/manga reader for gnu/linux)

Here are a couple of my recommendations.
(sorry if they have been already mentioned)

TeamViewer
Awesome free remote control software for Windows, Mac and Linux
There is even a iOS App of teamviewer in the apps store for free.
Availble Here
(allows you to remote control a PC/Mac even over 3g/wifi on a iPad/iPhone)

MplayerX(Mac only)
Mplayer with a nice gui and support for Mac OS X.

Revo Uninstaller is a pretty useful when you can't uninstall programs you don't want by regular means. For example, there's something wrong with the program itself and its uninstall application doesn't work.

File Hippo Update Checker: Saves some time and effort.

Why you think uTorrent is the best torrent download program?
EDIT:
Startup Manager - manage the programs who start when your computer turn on.

Darik's Boot And Nuke if you're in a hurry.
Eraser if you want to be a bit more selective. Keep in mind though, that Windows' shadow volume copy might still fuck you in the ass and it's quite hard to get rid of stuff that's been saved there.

The best thing to do, is to store everything encrytped in the first place. TrueCrypt comes handy for that... especially since if offers "plausible deniability" that is you can create 2 levels of encryption and later reveal the non-incriminating 1st level if its demanded.

"In July 2008, several TrueCrypt-secured hard drives were seized from a Brazilian banker Daniel Dantas, who was suspected of financial crimes. The Brazilian National Institute of Criminology (INC) tried for five months (without success) to obtain access to TrueCrypt-protected disks owned by the banker, after which they enlisted the help of the FBI. The FBI used dictionary attacks against Dantas' disks for over 12 months, but were still unable to decrypt them."

How about Team Viewer, its a program that lets you share files through the internet from one pc to another pc or through local area for those people who have a hard time figuring it out manually.

Hope this would help for the contribution. :D

This is what I want to know too.
I have literally zero knowledge in programming though.
But I really want to create a visual novel too... *cougherovisualnovelcough*
The only thing I can do is the art ＿|￣|O"

Not a program, but rather an incredibly useful site that lets you create one click custom installers for basic programs and software to load (mainly on new builds). Works quite nicely and helps a lot if you have a fresh install you want to get up and going right away.

I've made a downloader for TheDoujin, it may not be very beautiful but it gets the job done (only tested it a few times though). I've only tested it on Linux so I don't know if it works in Windows, especially due to "./".

Sweet. how about this.

Desktop customization tool:
