SqlSync lets you compare two databases to see which tuples have been added, removed, and changed. You can also use SqlSync to make one database a clone of another and maintain its contents to be that way. One benefit of using SqlSync to perform synchronization is that you can perform heterogeneous syncs -- for example, from MySQL to PostgreSQL.

Hardy Heron has been designated as one of Ubuntu’s periodic Long Term Support – or LTS – releases, for which the company commits itself to providing three years desktop support and five years server support. This means that Hardy Heron isn’t going to go anywhere soon; it’s here for the long haul. This invariably means the designers have focused less on putting brand new stuff in but rather more stability, more robustness and more reliability.

Fedora 9 booted up from the 2GB USB stick I used, and, through the virtue of solid state, did so a lot more quickly than CD-based LiveCD images do. I used my portable Fedora 9 system to browse the Internet. I downloaded some things, and I installed a piece of software, too.

Like VMware VirtualBox is a program that runs on the operating system of the machine on which it's installed but which provides a complete virtual environment which enables the creation of virtual machines that run other operating systems. These systems are usually termed guest systems, in contrast to the host operating system which is installed on the real, physical machine. It means, for example, that a host system running Windows XP can have guest systems running Linux, other versions of Windows, Solaris and so on.
