FOSS spawns a huge number of applications, anyone who has seen freshmeat can confirm that. Very few of them really reach usability and even fewer are well maintained. So here are some I found lying around in my own harddisk, along with the rpms mirror I pulled out sometime back.
Ever since I saw XGL (more correctly compiz) doing extra magic during the kororaa demo at NITC, I've been wanting to try it out. But this one was a surprise - 3ddesktop. It is basically a 3d desktop switcher that could be hacked around to work like XGL has - but minus the actual X updates across the multiple faces.

It is the most awesome thing I've ever seen work out of the box. Even without restarting X11, it just started working. The screenshot is of carousel mode with zoom enabled. You can see my four desktops and the various things on them. OpenGL rules.
The night sky in Bangalore is orange. We have too many glowing streetlights to actually see the sky. While I was in NZ, I remember walking around in the garden at 2 AM looking at the stars I've never seen before. I've marked out the Southern Cross in Celestia and now I can watch them anytime I want. Anyway, a set of spots with no connections hardly makes any sense to the average viewer. Then there's that small blue planet that is hardly even in the middle of nowhere that we are quite interested in.
But before I started bitching about the lack of marked constellations in Celestia, I ran into something that's even more awesome. This one is a virtual planetarium on your desktop - Stellarium. This thing literally blew my mind away. There is no other program I've ever seen that makes me want to plonk down hard cash. If I ever go to a college to talk again about the coolness of software, I am sure as hell going to demo this particular application. Head and shoulders about the rest, that's what this one is. This is a bloody video game, that is what it is. There is even a windows build for it.
All the following images are screenshots captured from Stellarium. If I'd pulled the ones without markings, you could misunderstand them for real photographs. If you don't believe me, look at the bigger versions.
I don't know how many of you have played an old DOS game called Xargon. But I am pretty sure you guys have seen one of the Mario series at least. So, supertux is a side scroller of the very same sort. Except for the lame save file style - which is a plain-text lisp macro file, I love the game. Maybe I might love it better because of the lame save file *wink* *wink*.
Then floated before my very eyes, something that was even more annoying than anything before (and probably after). Something that burns CPU just to render on screen and even more because of all the composition on the backbuffer. I give you xpenguins. They even have themes, like the Simpsons with Bart & Lisa. The most awesome part is when the penguins fall too far - they die with a lot of gruesome blood and fly away as a angels. I literally died laughing when Bart mooned standing over a root terminal.
There are serious tools in there as well, like redir. This is a port deflector which accepts connections and forwards them elsewhere. Looks to be a lot cleaner than using netcat/ssh for the job as I've always done. But yeah, those are almost on every *NIX box - this might not be. Or hping which can finally send SYN pings which aren't blocked by most boxes. Technically you can take down entire blocks of webservers using that simple tool - not Yahoo!'s or any decent company's servers, but not everyone knows what Accept Buffering means. For the really paranoid security dudes, there's the knock which lets you script up your port knocking. How about if I hit 3333 and 6666 twice within 10 seconds, the firewall lowers the connections to ssh-22 for next minute - well, then I'd really need knock around or I'll be writing LOTs of code in the link layer to detect hits on closed ports. And ssh proxy-command has the ideal thing for it - nc host port1 ; nc host port2 ; nc host 22 .
Also when you walk around a wifi network, you can't do without kismet or in a pinch, ssidsniff. Last cool toy around is the fakeap which lets you fake the existence of hundreds of 802.11 accesspoints with a few thousand beacon frames. I wonder what would happen to the poor guy who tries this at a conference - killed by a thousand laptop blows ? Or maybe run driftnet on a host with lots of traffic and see how many naughty pictures people browse.
It is already the next day now and I still haven't played around with torcs, dircproxy or qdvdauthor. More importantly, I haven't really tried out all the network tools that are so important to my basic mode of operation. Maybe sometime later.--
