Yay for 2009.0

Hey guys, I'm back with a brand new operating system :)

After installing I encountered some bug with the display manager that made the keyboard stop working after a while so I needed to use KDM 3.

KDE 4 is awesome! Here's a screenshot:

I'm still a bit unfamiliar with the changes though :( I can't find the new hotkey for "Show desktop", which used to be Ctrl-Alt-D in KDE 3. The PrintScreen key doesn't seem to work, and I need to run the ksnapshot command to take a screnshot. The desktop setting to change the monitor gamma is gone, and I need to use the xgamma command. And more...

Let's try to tame this new penguin :)

Mandriva Linux 2009.0

Mandriva announced the official public release of Mandriva Linux 2009.0 yesterday. It's the first time in many years they've met their scheduled date! I am downloading it now. Wish me good luck!

Winzip password collision

I created this zip file for a word guessing contest at ForumWarz, using a strong password, "5be890c219b0a837600e5fbb7ae8a2505be890c219b0a837600e5fbb7ae8a250" (not insanely strong but I guess that's strong enough for an average user). But it got cracked easily using AZPR with a brute-force attack.

It turned out that you can unzip the file with a much shorter password "tdc4Dl" too.

Surprised? I knew that zip protection was insecure but never thought it was that terrible.

This paper has some more information about zip encryption weaknesses, but I'm too lazy to read something that long. Maybe rhican can enlighten me :)
