Gimp is fondly referred to as the poor man’s Photoshop. This wonderful application allows you to edit, create, resize and crop images. And these are but a fraction of the features on offer.
While Gimp is an excellent application, it may be a bit too much for such mundane activities as viewing images or changing their formats. For this the perfect tool is FastStone, which offers a number of features including viewing of every major known format, resizing, color adjustments etc. It does not offer a portable version, but it can be carried in a folder as it does not need to be installed for it to work.
Like Firefox, VLC needs no introduction. This multimedia player offers compatibility with virtually every known AV format, and supports streaming and transcoding. Keeping in mind its relatively small size of 9MB, it easily finds a place in this roundup.
you should try the newer version of putty. It has now an option of serial connection as well.System Administrator's now say goodbye to hyperterminal and start using the newer version of putty. Enjoy.....
