Ubuntu 9.10 has been released. Attached are the torrent files as the mirrors are busy as usual. There are many improvements to both Ubuntu and Kubuntu. Help the community out and seed these torrents please.

But not too busy to post this. The machine is still responding great.

I just got GMail working as the default email client for KDE. To do this, go to KDE Menu -> Computer -> System Settings and click on Default Applications.

There are plenty of notes on getting this working out there, but getting the subject and body working can be tricky. Select the radio button next to Use a different email client: and enter the following:

/opt/google/chrome/chrome https://mail.google.com/mail/?view=cm&fs=1&tf=1&to=%t&su=%s&%u

replacing /opt/google/chrome/chrome with the command for your browser.

I had to take a closer look at a distributed attack on one of our web servers today. The attack only involved around 50 hosts which seemed to be testing our URL parameters for injection susceptibility. Coldfusion has some protection against SQL injection, and we take extra steps, as every programmer should, to guard against it.

After identifying the attack vector, I was able to grep the log file for the signature of the attack which was present in the URL information.

I installed Google Chrome for Linux, the developer build, just to see what it was like.

It's fast; It is extremely fast. I wasn't planning on using it day to day, but I find myself clicking on it more often than Firefox.

The fact that it has no easy ability to block advertisements is pretty much overshadowed by the browser's sheer speed and usability.

And I don't like advertisements. I wonder if this is what Google is banking on.

I'm typing this on the second laptop I've ever owned, and the first one that actually shows the color red on the screen. I purchased an IBM Thinkpad R51e on craigslist for $150.00. There's nothing really special about it. It's a very solid machine, has a 2.6 GHZ Pentium M with over a gig of RAM, a CDRW drive, and a 15" screen. It does have a 4200 RPM, 40 GB hard drive, but I can buy a 5400 RMB, 120 GB hard drive for less than $70.00 new.

Sometimes, it becomes necessary to recover deleted files from an NTFS image. Using linux, a free utility called ntfsundelete can be used.

If the image is still mounted, you will need to unmount it:

$ sudo umount tmpmount

Then, you will want to use the losetup utility to associate a loop with a regular file (our image):

$ sudo losetup -o 15443968 /dev/loop0 /media/2Big/hd.img

The -o is the offset calculated from the last post (the start of the partition listed in fdisk * 512). The ntfsundelete utility can then be used:

$ ntfsundelete -s /dev/loop0
