Oracle buys Sun

In this week's edition of Roundup: Oracle to buy Sun Microsystems, Ubuntu 9.04 gets released and Microsoft shows off new Windows 7 security features.

The big news this week was the acquisition of Sun Microsystems by Oracle for US$7.4 billion, spurring both positive and negative reactions. According to an Australian MySQL expert, the popular open source database won't suffer as a result of the buyout, but will complement Oracle as a company.

Ubuntu version 9.04, dubbed Jaunty Jackalope has been released, bringing, amongst other enhancements, a faster boot-up and a new integrated notification system. It comes in three versions -- desktop, server and netbook.

At the RSA 2009 security conference, Microsoft unveiled the new security enhancements for the upcoming Windows 7, including BitLocker To Go and AppLocker. BitLocker To Go offers encryption for removable storage devices, while AppLocker enforces code signing, so only trustworthy applications are installed. I recommend watching the accompanying video for more information on the features.

Also at the conference, a Microsoft executive stated in a video interview that older versions of Microsoft operating systems are more vulnerable to attacks.
