Release early, release often - we might be able to help you make it better

Great job in front of the camera, actually. Never once did you strike me as nervous or unsure.

Nice work, and w00t for Gentoo in the classroom.

Hey Ketchup, you mentioned earlier that all your labs are identical. Instead of compiling the source (with distcc) 20 times (once per computer), wouldn't it be easier for 1 distcc compile of the source, quickpkg it, then emerge -K the provided custom binary package off the servers distfiles directory? If you already started doing this, than I guess there is more behind what you do with the script.

That's a good point, distcc operates at roughly 85%. You could probably eat up soem of the final 15% with this method, using some kind of program/script and a database of the already-compiled packages. It might also save on network usage.

Question:

How does he set it up so that he installs a program on all the computers at once? (forgive me noobishness).

Was something like ltsp ever considered for your labs?

hey man, awesome to see you in the news with something like that... makes me extremely happy we're making our way into the public mainstream!

Thats a very interesting way of doing things. I previously didn't see any advantages of Gentoo outside of hacker workstation use, but that enlightened me. Thanks

As for the dog: I AM IMPRESSED. That's very cool. Indeed.

You might think of ogg as being difficult; but in circles such as these, it's not. We know what's best for us.

PS: Ignore the idiots who always want to bitch and complain. Everyone worth impressing was impressed.

Estimate of network traffic generated from mirroring these clips:
4550431320 bytes over approx 190 days.
208 requests for the high-quality ogg, 172 for the low-quality ogg and a mere 36 requests for the divx version.

I hadn't seen this video before, I think this chap does a good job of simplifying the subject for the intended audience.

Old news, but I actually watched the video this time! The mispronounciation is funny

Haha, she pronounced it pretty badly.

Cool!

Obviously... he uses distcc and one of the various cluster ssh tools (maybe).

Wow, I had no idea this thread was still active. What you suggest is exactly what I do (and have done all along). I compile on my (teacher) computer using the student workstations to speed up the process (tremendously). The /usr/portage/packages directory actually sits on NFS. I then "activate" an upgrade script (super-simple & home-made) which is run when the student workstations reboot, updating them using the latest packages on the server. The only downside is that this doesn't work so well outside of the lab, because our teacher computers are more of a mish-mash of hardware, so I am working on a separate "generic" package repository (i686 vs Athlon, and no fancy CFLAGS / USEFLAGS) for the non-athlon hardware we have. I definitely am 100% behind the compile once, distribute many times (bin packages) approach.

Saw it here in Millinocket myself, good job. I read about your school a while back when i was doing some work for my old High School. Keep up the good work.
