If you don’t want to fork out 300 bucks for Adobe Illustrator Inkscape is definitely an alternative. Inkscape is an open-source alternative to software like Illustrator, Xara and Freehand. It has most of the stuff commercial software has, but with a slightly different interface. The developers used the GNOME Human Interface guidelines when designing the program. It is pretty clear that Inkscape has a legacy from another open source illustration program, Xara Xtreme. As a matter of fact the two open-source projects are sharing some features and experiences.
If you come from an Adobe-world like me you will probably be annoyed of the different interface, but after a while one discovers that it’s pretty nice and even uses logic. Of course there is also the process of re-learning all the shortcut keys (why can’t someone standardize them).
A drawback with Inkscape is that it doesn’t handle file-formats from Adobe Illustrator and Freehand. So if you are going over to Inkscape, don’t forget to save your Adobe-files as SVG or EPS. Inkscape can save to some interesting formats, most noteworthy PDF. The PDF saving feature is fast and does the job without any problems at all.
I tested Inkscape with Windows Vista and had no stability problems whatsoever. It runs smooth, and feels a lot faster than similar Adobe products. It also takes considerably less time to load. There are also versions of Inkscape for MAC OS X and Linux. The program is considerably small; the installer is just 21 MB. It’s even possible to carry Inkscape around on a USB-stick.
There is one down-side with Inkscape, the program can’t export to Flash and it has no built in animation capability. But for pure illustration purposes Inkscape is quite competitive and is a great product for amateurs as well as pros.
Data protection is all the rage these days, and you can’t be too careful. TrueCrypt is an open source alternative to a number of encryption programs out there. Actually the program is based on E4M (Encryption for the Masses) released in 1997 and discontinued in 2000.In order to store encrypted data TrueCrypt uses system volumes, the program basically creates a password protected and encrypted volume. If you provide the right password the volume is unlocked and you can use it as any other volume on your computer.
The program has a number of encryption algorithms you can use including; AES, Serpent and Twofish. All of the encryption algorithms are standards with AES being the most widespread one. If you want an extra layer of security it’s possible to create volumes that requires two-factor authentication using a keyfile. In order to unlock the volume both a password and a special keyfile is needed. Creating a new volume is done using a simple and easy wizard, almost any user can do it. Mounting a volume (which needs to be done every time you restart the computer or dismounts the volume) is also easy. It’s a matter of choosing a volume file and clicking “mount” . It is entirely possible to have 250 GB of data or more encrypted and use it as any other normal volume, you can even install programs on your encrypted volume.
TrueCrypt has the ability to run in traveler mode, which means that the program does not have to be installed on the OS it runs. This means that it is possible to take TrueCrypt with you on trips using a USB-stick, so you can bring business secrets on the road without having to worry about the data getting into the wrong hands.
The program also comes with a number of language packs, as always with Open Source software these kind of packs differ in quality and translation. Also with a fairly straightforward program like TrueCrypt there is no need for language packs.
