SAP SHAValidator

Tuesday, April 6th, 2010

SAP SHAValidator is used to ensure that files downloaded from the SAP site have not been corrupted during download. It does that by calculating a SHA256 cryptographic  hash. The problem is that this utility is provided as two JAR files, namely SHAValidator.jar and frog.jar, the later being used as look and feel library. As a result, a long command line has to be issued to launch the utility. I combined the two JAR files into one so as to allow a double-click launch of the utility or issuing  java -jar SHAValidator.jar via the command line. Download SHAValidator here.

Moving to Linux

Monday, April 5th, 2010

I finally moved to Linux on my desktop. After trying Ubuntu and OpenSUSE, I finally opted for Ubuntu as it has been easier to install software such as Limewire, Google Chrome, Skype and VirtualBox on top of a fresh installation. A word of advice though: Right after a fresh install, launch the auto-update so as to get the latest patches. Failing to do so will make the installation of the previously mentioned software troublesome. Crossover can be used to run windows applications and games on linux. This company is actively contributing code to the Wine opensource project.
