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>
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...
