Exclude directories from chown

There's been times when I needed to recursively change ownership of files in a directory but leave certain files alone (e.g. snapshot folders). Came across a highly useful post from Posteet on how to do it. In my case, I needed to exclude directories owned by root and the .snapshot directory. So # find . -xdev -name .snapshot -or -user root -prune -print | xargs chown < user> :< group>

Flash game: Cargo Bridge

Image
I came across this fun little puzzle game called Cargo Bridge on Kongregate . Most levels are quite do-able (with lots of walkthroughs available if you're stuck). Thus I shall only post solutions for the more difficult levels. Oh, and the game is a little buggy so if solutions which should work keeps failing for some reason, try deleting the offending joint and rebuilding. Or quit to the main menu and restart the level. Level 12: A non-optimal-but-definitely-works solution for those who are stuck. =) Level 16: This level is quite a pain. One of the suggested solutions on the walkthrough actually had an arched bridge which didn't work well for me as the little guy got stuck. I then came across another solution which was flat, but broke too easily. Thus I modified the support structure and hey presto, it worked! Level 18: Probably one of the most difficult levels. Thanks to Tasselfoot for his walkthrough on YouTube for giving birth to this solution. Don't worry if...

Copying Sony recovery partition to new harddisk

For those whose harddisk (HDD) are dying or simply looking to upgrade to a bigger, faster drive, here's how to backup your hidden Sony recovery partition to the new drive. Firstly, plug both disks to a computer. For me, I plugged both disks to my desktop (with my original desktop HDD unplugged to avoid accidentally messing with it). Next, get a Linux live CD. There are a few variations available, most commonly Knoppix and Ubuntu . I'd go with Ubuntu for this example. Boot the live CD run the software Disk Utility in Ubuntu to check that both HDD are detected. Make note of the drive letters for each. For my case, as the original is the master drive, it is detected as sda and the new one is detected as sdb . Create a partition in the new HDD about the same size as the hidden partition (around 10GB). Fire up the Linux terminal and copy the hidden partition over. (Note that your partition number may vary. Use Disk Utility to check for the correct partition numbers.) sudo dd if=/d...
