Re: [gentoo-user] any gentoo mutt users?
Bingo. Mutt works great as an IMAP client (which is rather interesting because, to the best of my knowledge, mutt did not support IMAP until somewhat recently, and quite a bit after it first appeared). I personally do everything via IMAP -- no worries about switching mail clients and having to convert emails. I don't know what there is to criticize about IMAP. ;) It's infinitely better than pop for the grand majority of users. It is somewhat strange, however, that almost every mail client on the planet can scan all the mail folders available / used and let the user know if there's a new message, but mutt seems to struggle when is a very large number of (large) mailboxes. Mutt, actually, has a built-in mail checker. To use it you have to (a) use mbox format (I believe), and (b) set the mailboxes you want monitored in the .muttrc using a format similar to the one below: mailboxes +Stuff mailboxes +moreStuff This works great when I have one or two mailboxes listed. But when I set a mailboxes directive for every one of my mbox files, mutt ends up practically hanging and becoming unusable about 95% of the time. It takes about 5 minutes from executing mutt until I can start using it because it tries to download every single email to keep track of what is already there so it knows when a new message arrives so it can warn the user. I imagine I'm not the only person who has had this problem in the 14 years mutt has been around. ;) I guess that's why gbuffy and xbuffy were created in the first place. Funny how these older tools (mutt, *buffy, etc.) seem to work better than all the newer GUI tools like gnubiff, etc.). They just don't seem to make things the way they used to. ;) -j On Sun, May 3, 2009 at 6:05 AM, Alan McKinnon alan.mckin...@gmail.com wrote: On Sunday 03 May 2009 11:44:39 Mike Kazantsev wrote: It's certainly an alternative, however, if I can't find anything else that works.

Re: [gentoo-user] Moving an installed system to RAID10
Or you can create raid0 with partitions on both drives (sda1+sdb1) and mirror it on the second set of partitions on the same drives. But then you do not have any protection from total disk failure you'd normally expect from raid1. Only some very little protection against a sector failure. Plus two equally strange configurations where you first create raid1-mirrors and then strip them to raid0. Doing raid10 (or raid01) with only 2 disks is imho not a good idea... It is very well written everywhere that deals with raid that it is a very bad practice to have more than one raid device per drive AND per bus. Having two identical disks and a need for redundancy calls for raid1 (mirror), nothing else. Or anything else is just fancy crap, but hey, you can learn a lot with fancy crap. If you wish to get something a little more than raid1, it might be with raid6: partition each drives in 2 equal sized partitions, then create the raid6 on those 4 devices. You loose both reading and writting performance due to seeking from one partition to another, but you keep redundancy since with raid6, 2 device failures can happen. The advantage here, is scalability: you buy a third drive later, partition it correctly and 'grow' your raid6 on those 2 new devices. But even then, if you buy a 3rd drive, i'd recommend raid5 simply on the whole disks (well one partition per drive). Here, do whatever scenario you want, and when you buy a 3rd disk: fail and remove the secondary drive on current raid create a raid5 with the new drive and the removed spare and 'missing' copy old raid over to new raid fail old raid and add its device to the new raid update your /etc files to point to the new raid Enjoy!

Re: [gentoo-user] sync'ing two computers (not related to emerge)
How long is unison taking to check for changes? I can usually reconcile changes in my home directory (approximately 45G, 125,000 files) in less than 10-15 seconds between my slow laptop drive and a remote machine. However, if you are syncing with a Windows machine, expect the sync to be much slower. Fast checking is not safe on Windows, as unison can miss changes, so it scans every file every time unless you tell it otherwise. Ok i had to try a few times and now with tcpkeepalive being turned on it doesnt disconnect. But when the scan is done, it 'reconciles' the changes (so it has received the changes from the remote end) and Begins the transfer of a dozen files, but not a bit is transfered. The sshd and unison process on the remote host are waiting/sleeping or in coma, but nothing happens. I just tried again and let it sit on the transfer to see if the processes would wake up, but it read from remote host that connection timed out. I'm not sure but this may be due to the fact i'm on an unstable link... I'll try once more with a ssh session on the side to see if that session will get disconnected or not... It would be so nice if unison could 'remember' the changes on my HD against its local archive... anyway... Thanks, Simon

[gentoo-user] nanosleep broken on ~amd64?
By accident I noticed that the configure script for one of the gentoo

different results on ~x86 and ~amd64.
The script uses a test for working nanosleep that I've included below.
Could someone else compile the test and confirm that it returns 119 on
~amd64 instead of 0?
Here are the steps if you don't already know them:
1. Copy and paste the c code below into a new file named conftest.c
2. # gcc conftest.c
3. # ./a.out (don't forget that leading dot)
4. # echo $? (this should print either 0 or 119)
I get 119 on ~amd64, which implies the test for nanosleep fails.

If the link dies and comes back, unison (at least version 2.27.57, what I have here) gets confused and just sits there. What's interesting is that if unison is killed on the initiating machine, the remote process stops as well, which leads me to believe this is a bug in unison; they can talk, but they don't do anything. I've glanced at the code before despite my lack of familiarity with OCaml, as my wireless connection will often die, causing much grief, but I've never found a solution. You could try syncing subdirectories iteratively within what you want to sync and hope that your connection does not die during the smaller sync, but that really isn't a good solution. I personally use this method to speed up synchronization if, for example, I only need my latest CS project synchronized but not any new music I may have. Unison is smart enough to use the same hash database if you use the same root directories and use the Path directive in your configuration to limit what is synchronized, so it should not re-hash your files on a later sync. As for other solutions, if you cannot get unison to work with your connection, I would suggest using a DVCS. I tried synchronizing my home directory with git before finding unison. The DVCS approach is better than SVN or CVS because it takes up less space and does not require a server. The disadvantages are the increased space used to store the backend files and the need to commit all of your files before pushing/pulling to/from the other machine (though I guess that could be an advantage, depending on your needs). It isn't optimal, but it can work, despite the git manual specifically mentioning that git was not made to do such a thing. Mercurial might work better, but I've never tried to use it. You might hit the same issues if the connection dies; I don't know. If you do find something that works similar to unison, but is more robust, I'd love to hear about it. I've tired a number of things, but I keep coming back to unison, despite its issues. Regards, Brandon Vargo

[gentoo-user] USB barcode scanner

Thanks, It doesn't look like you have the HID keyboard version. I have an ID Tech IDT4439U which when plugged in behaves like a keyboard. In the following lsusb output, notice the iConfiguration and bInterfaceClass parameters. My wild guess is you will need a driver.

I've been comparing the system files against my other gentoo machine and they are just the same. However the fact that motd appears twice even when I login as root continues to puzzle me. I've checked all user accounts and only 3 out of 37 accounts have the login/su problem. I will create some new accounts and see what happens. Thanks, -- Valmor

Also, ksystraycmd from KDE4 has segfault in nanosleep every time, forever. Maybe it's related?
