I installed Davical on my Ubuntu 9.10 box last year, and it was pretty painless, and worked well. The web interface was pretty kludgy, but maybe there are some add ons that could improve it, i don't know, I always used a client program on my other machines to access it. I didn't use it extensively, and so I'm not using it anymore, but for the time I was using it, it just worked and got the job done. I didn't actually try and get my ipod touch to connect to it, so I can't speak for that. Best of luck. -peter ___ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss

I was > looking at the Dell Zino, but am unsure if a better option exists. I built one myself with a Mini-ITX board with an integrated Intel Atom 330 (dual core, 1.6GHz) I don't think the motherboard I bought 2 years ago is still around, but there are plenty of alternatives. Most motherboards these days have a power on after failure option in the BIOS. I used some spare SODIMMs, a cheap case, a couple lower power hard drives, and an 85+ efficient PSU. The whole thing cost ~$400, and I've been very happy with it for the past couple years. It uses ~40 watts at idle, and ~50 watts when it's cranking. My suggestion, is therefore to build something yourself around a MiniITX platform. :) -peter ___ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss

It's not nearly as well polished as dropbox, but for basic stuff, it works okay. It doesn't need any resources you don't control. It does use an IRC server to communicate the hash of the latest commit, but you can pick your own server. Also it's git on the backend, so it stores everything twice, once in the local repo, and once in the working copy. (origin, master? my git vocab isn't that great) So if you drop 20GB of binaries into Sparkleshare you use 40GB of local disk. This is annoying. hbons is working on some other backends. I think it's got some potential, but it's a ways out. I've also used SpiderOak. Dropbox has far and away the most polished UI of any "cloud storage" program I've used. -peter ___ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss

Matt's suggestion calls grep and cut for each variable. This creates a lot of
process churn, and will become a slowdown if you have a huge number of
variables. But you probably don't.
Are you restricted to Bourne, or can you use BASH?
I know BASH can do fancy string manipulation, but I don't think it's doable in
Bourne.
In BASH, i'd do something like this: (assuming I understood your question
correctly)
(my input file)
$> cat file
var1=foo
var2=bar
var3=badidea
(my one liner)
$> while read line ; do export ${line%%=*}=${line#*=} ; done < file
refs:
http://linuxgazette.net/18/bash.html
Of course, one has to ask why your co-worker is doing this, and not just
sourcing the file.
Also, my example will break if you have an equal sign in your variable name or
value name.

I redid this test and got the same results. So I wonder if the problem could be that the BIOS has to detect all the drives during the POST sequence, and that the drives aren't all spinning up and registering with the BIOS fast enough. It's a long shot. Check if your BIOS has options for staggered spin-up of the drives. Also try disabling the "quick boot" option that a lot of BIOS have. Also see if there are updated BIOS for the motherboard, and check the change log for anything that sounds like it might be related to your problem. The device ordering might be getting messed up. I'd start by walking though all your BIOS options and see if you find anything that sounds like it might help with HDD detection. Of course, power problems do seem likely, but it doesn't quite add up. Does your PS have a breakdown of the max current output on each voltage line? 3.3v, 5v, 12v? -peter ___ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
