Yesterday i installed latest Archlinux i686 on a 8Gb USB stick, not live, normal installation. Sometimes i loose my pendrives so i decided to encrypted it. I used LUKS an LVM, i mapped de partitions as /dev/sdX...., but i'm thinking about to change to UUID because I have a hell of machines at home with several drives each one and if i leave it like that , probably i'll have some problems. So i'm not sure if that i want to do is possible or not, i want your advice...,because i don't know if during the encryption with LUKS and partitioning with LVM the targets names /dev/sdX are untouchable. So i want to: 1.- use blkid to obtain de UUID from normal partitions like /boot, cryptdevice like /dev/sdb2(in my case) and mapped partitions of LVM like /dev/mapper/lvm-home and /dev/mapper/lvm-root 2.- change /dev/sdX by /dev/disk/by-uuid/XXXXXXXXXXXx on fstab and menu.lst (leave fallback untouched, :)) . . . Well, i have to tell you that while i'm writing this comment i'm trying to make it. . . and it works!

I find GUIs very unfriendly these days. As soon as there's a problem they leave you stuck with no idea what just happened.

I'm just working into a linux one, now the code is REALLY REALLY quick and dirty (sorry, i did a lot of experiments). It's fast full-band in a 1GB network , but i have to optimize more for 10GB. I'will past you the proof of concept and oprofile. The current bottleneck is linux kernel stuff (copy_from_user mainly but not only) : the code http://pastebin.com/m6cbccebf oprofile stuff: http://pastebin.com/m3d088e9e http://pastebin.com/m57e44d17 Hi, are you the Yannick Loth who posted for a efficient packet sender ?

Is it looking to provide real-time synchronous collaboration? If so, the Plutext AMP module may be of interest - http://forge.alfresco.com/projects/plutext/ - especially once you are able to use docx4all - our Swing-based word processor - as a collaboration client. cheers Jason Hi Yannick
