Ubuntu 9.10 Beta Is Available for Download

A few minutes ago, the Ubuntu development team unleashed the Beta release of the upcoming Ubuntu 9.10 (Karmic Koala) operating system, due for launch in late October this year. As usual, we’ve downloaded a copy of it in order to keep you up-to-date with the latest changes in the Ubuntu 9.10 development.
What’s new in Ubuntu 9.10 Beta? Well, as you probably already know, there is now a revamped Human theme, the Humanity icons and lots of wallpapers! Moreover, the Ubuntu Software Store has been renamed to Ubuntu Software Center and updated several times in the last two weeks. And… in order to improve the boot performance, the Ubuntu developers have now transitioned to Upstart.

Ubuntu Software Center

A new security feature included in the 32-bit Linux kernel that Ubuntu uses is Non-eXecutable memory protection, which has been enabled by default for quite a while now on processors that support the NX feature, but it has been useless for systems that have lacked support. From now on, the kernel provides an emulation of the NX feature for all these other processors, potentially blocking many exploits targeting the stack or heap memory.
A lot of the applications in the repository have been compiled using compilation flags that create Position-Independent Executables, which enable them to take advantage of the Address Space Layout Randomization function that is available in the Ubuntu kernel. That way, when the programs load themselves into memory, they don’t always use the same layout, so an attacker can’t redirect the program’s execution in the same way every time to run exploit code.

GNOME 2.28.0

"We’ve done some work on improving the overall look and feel of booting the system. Please open bugs with the tag ‘ubuntu-boot-experience’ on any messages you see flashed after grub loads and before the new Ubuntu Splash screen (xsplash) displays. If you have trouble catching them before the splash screen loads, you can also check vt1 or dmesg output for copies of these messages. We also accept photos or video attachments if that’s easier, however please make sure the text is readable." – was said in the announcement.
The home folder encryption option in the installer is back, and after the installation, when the desktop appears, you will be prompted by a dialog to set up the encryption passphrase, in case you will ever need to recover your data from the encrypted partition. See the picture below…
