I've recently build myself a "Poor Man's RAID Array" out of 8 x 300GB drives in software RAID5. After reading about Sun's ZFS, I'm wondering if there's a way to do something similar to their "disk scrubbing" with Linux's md raid.
Basically run through the array and check each stripe against it's parity, and re-write (to attempt to fix) the stripe if it doesn't match.
At least it's something to think about, since two disks could get a small error, each on seperate parts of the disks, and then the RAID5 rebuild could fail when you try to rebuild it after a disk fails, even if there is enough data to reconstruct the missing parts.
I can (and do) occasionally do that. It works great, in fact. The only problem is that my home's net connection is so slow, it's just faster to download directly on a machine at home, then upload it all at once via sftp.
I was just pointing out that even though it has very legitimate uses, it's still blocked completely at some places...even places where it should be acceptable to use it.
You're lucky they only block by port. My school (CA State Polytechnic Univ Pomona) blocks by packet content, so I can't just change the port.
On the humorus (and annoying) side however, some part of the network infrastructure related to the scanning crashed a LOT the first year they had it running. The 'net would "blink" on and off every 5 minutes or so throughout the day. (It makes SSH'ing to your home to get some work done _impossible_.) It took them a whole year to get it fixed.
This is my personal favorite as well. I used to use Smoothwall, which is not a bad choice, but from what I can tell, m0n0wall is more secure, and takes a lower powered machine to operate.
I'd give it a try. Get it from http://m0n0.ch/wall
It's got a nice user base, post to the mailing list if you need help.
At our school, anything that can be routed across internet2 gets routed there automatically. For example in the dorms here, if I connect to another school that has internet2 access, it goes across internet2.
It makes downloading linux iso's from other schools that have an internet2 connection fast. Very fast. Too bad we only have 10mbit lan here in the dorms, because it does max that out.

The video is awesome. I love the nice touches, like the controls for the guns, and the self-lowering windshield.
I feel about the same here. I just hope that the upcoming FireFox is based on what was to become Mozilla 1.8 as was originally planned. It's quite a bit faster than FireFox is right now.
Yep, I've found mozilla to be faster than firefox at rendering, in linux at least. It is most noticable to me on pages with lots of flash ads.
The only reason I'm not using mozilla on linux is that I don't know how to make it do the url completion that I get in firefox (control+enter=.com, alt+enter=.net, control+alt+enter=.org). If anyone knows how to make mozilla do that, I'd like to try out mozilla again.
I agree. Why bother duplicate the effort to write the same code between projects. Heck, open source projects should be encouraged to use each others code. That way some things could get done faster, and you already (hopefully) have some relatively debugged code that does what you want.
This is probably just a matter of someone having an inflated ego.
It's pretty good. It definitely starts up faster than OpenOffice does, in both windows and linux. I would say that it doesn't always open.doc files perfectly though, especially if there is a lot of complicated things in the file.
Other than that, both are great, but I tend to use OpenOffice more since I need to open.doc files all the time.
Where I work we are developing a few different boards that all use embedded linux on an Arm9. I think that Linux may develop to take over that market really well. After all, who needs a full blown Windows installation on an embedded device? And is Windows even capable of running on an MMU-less processor?

Set up a torrent next time, and promote using that. I know I would, even if it's slower initially.
