Re: [gentoo-user] Awesome vs Xmonad
Hi Man, I was a huge fan of FVWM (loved the flexibility of it) and I tried to switch to awesome. After trying a bit to understand how the configuration script work (about three days in my spare time), I understood how awesome (this one was easy :-p) this wm is. You can do pretty much what you want as the configuration script, which is using the Lua script language, can load system commands (such as conky, even thought I couldn't get it to work, but used native lua scripts with the wicked.lua library) or run native code (I use this to see the disk space, mpd songs, battery life, cpu usage with a graph, ...). One of the other things I really like in awesome, it's the fact that you can mix up tiling windows and floating ones. You can define, for certain window titles in the configuration file, the fact that they are floating. Then, when you start them, they appear as floating windows and not tiled as the rest of them. This is pretty much interesting for applications such as Skype, gitk, mplayer, ... As for other tiling wm, you can also assign tags (sort of virtual desktops) to window titles so when you start it, it goes directly there, leaving your actual tag clean with what you were doing. I have never tried xmonad, I can just share my experience with awesome.

The next day you'll be tired and bleary-eyed, and still a day behind. With RAID1 (or 5), you just plug in another drive. RAID should not be considered an alternative to backups, but a separate layer of data security. They even protect in the event of theft or fire which RAID1 doesn't.

[gentoo-user] Best website backup practice
I run on an old laptop a website (Joomla + MediaWiki + Moodle + a couple of other things). The site now is offline and I'm ok with my automated backups of all the hard drive, but it's going to go online in a few weeks and I'd like to add some more security. What I'd like to have is periodic snapshots of the site, so when the hardware will fail (I'm pretty sure it will, just a matter of time) I can easily transfer the latest snapshot on another machine running a web server and a databse. My idea is to cp (or rsync) the /var/www/host/ directory and, at the same time to mysqldump the related databases.

Re: [gentoo-user] {OT} Why RAID1?
I'm about to buy a couple Samsung Spinpoint F1 hard drives and I was planning on setting them up in a RAID0 array. Everyone seems to love RAID1 though, and I'm a little confused as to why. Don't daily backups secure 99% of the data that RAID1 does? They even protect in the event of theft or fire which RAID1 doesn't. If one hard drive dies in a RAID1 array, does the system keep running? If so, that's good, but there are so many other components that could die. In 15 years I've lost the power supply, video card, modem, motherboard, and CPU, but never a hard drive. With all these potential points of failure, how much greater system reliability do mirrored hard drives really offer? In fifteen years I've lost roughly fifteen hard drives and one power supply. Hard drives have moving parts and that equals failures. Congratulations on being lucky, though you have wonder why so many thing that don't normally have issues are having issues in your system. :-) Do you guys think RAID1 is unnecessary with an SLC SSD drive?

WRT writes it will pretty much nullify the advantage of having the SSD since all writes will be the speed of the slowest drive (the SATA). A write request is not completed until all mirrors are written to. You likely will have a slower reads as well since nearly half the time the reads are coming from the much slower SATA drive (i.e. the time you'll be waiting on the seeks/reads on the SATA will be much longer than all the reads on the SDD).

In this case you can just tell the Windows computers to print to http://cups server ip:631/printers/NAME using a generic postscript driver. Is this true for non-postscript printers? If so it's a great solution. I can get to the printers page on the server's Cups' GUI: http://192.168.1.59:631/printers It gives me a long, ugly descriptive name for the printer so I tried: lpr -P HP_PSC_1600_series_USB_1 optimize_mythdb.sh which did print correctly so I'm good to go so far. or b) A working printer for which you have the Windows drivers. You The Windows driver for this printer does not support network printing so I don't think this is an option. You shouldn't need a MS Windows network printing enabled driver to do this (with an lpd printer), nor a Samba client on your Linux boxen for that matter.

After trying a bit to understand how the configuration script work (about three days in my spare time), I understood how awesome (this one was easy :-p) this wm is. You can do pretty much what you want as the configuration script, which is using the Lua script language, can load system commands (such as conky, even thought I couldn't get it to work, but used native lua scripts with the wicked.lua library) or run native code (I use this to see the disk space, mpd songs, battery life, cpu usage with a graph, ...). Sounds great but when i customize the file and save it in ~/.config/awesome/rc.lua and reload, nothing seems to happen. I am trying to get working with awesome-3.1. Am i missing anything. One of the other things I really like in awesome, it's the fact that you can mix up tiling windows and floating ones. You can define, for certain window titles in the configuration file, the fact that they are floating. Then, when you start them, they appear as floating windows and not tiled as the rest of them. This is pretty much interesting for applications such as Skype, gitk, mplayer, ... As for other tiling wm, you can also assign tags (sort of virtual desktops) to window titles so when you start it, it goes directly there, leaving your actual tag clean with what you were doing. That is a required feature because some stupid programs dont go well with the tiling concept. Another neat feature i found in default xmonad was the fact that there was no gap between adjacent windows. I am sure awesome should be able to do that as well, just that the default conf doesnt. But, then again i really haven't dug in. In xmonad default, the size hint of some programs are ignored. Like terminal staffs, urxvt, xterm, gvim. So sometimes they will leave a half line on the bottom after certain resize action, as of new windows opened.

This is one place bash's brace expansion is sorely lacking compared to

man seq for more info.
In your particular case, you can do
for I in $(seq -w 198); do ... 0$I ; done
seq is more flexible in that it allows arbitrary formatting of the

If I'm left with any technical questions about doing this (and I am) then the first one is to better understand this concept of RAW print queues as brought up by Willie. I suppose the idea is that cups doesn't do anything to data arriving on that interface and just sends it to the printer? That way a windows machine might format a page using its own driver and cups just passes the data on? Makes sense to me, but it's all made up and I can't find any real info specifically about that yet. I don't understand yet whether my XP machine is using the 'raw' interface. It has a postscript driver so I suspect it's sending postscript. Is it then passed through 'raw', not converted by cups, and handled by my $79 freebie printer Apple gave me when I made the worst computer purchase of the nearly 30 years I've been using computers. (Mac Mini) I douobt that printer even knows postscript so I think cups must be helping out with that. Anyway, it really does work. It's not too hard to set up.

Re: [gentoo-user] Print to cups printer from Windows - any good instructions?
Yes, that would require Samba as at least earlier Windows can only share it via CIFS/SMB - at least, end-user versions. You might be able to get Win2k Server, Win2k3, or Win2k8 to do IPP only though, but I doubt it would be easy to get WinXP, Win2k Pro, or Vista to do so. If you can get Windows to share solely using IPP, then you would not need Samba, and it would be the same as configuring any CUPS client - at least that's my untested thought. CUPS can interact with Windows and other systems either in IPP mode or CIFS/IPP mode. For CIFS/IPP mode you need Samba to provide the CIFS layer. I would, however, strongly recommend that unless you really want to protect your printer via a Samba/Windows Domain (not likely on this list, but you never know), then just use the friendlier strip IPP mode for accessing the printer as the CIFS/IPP will just add overhead and headaches. (I got IPP working and just stopped there. It didn't seem beneficial to go any further for my small network, and I don't have any DOS, Win9x, or NT4 systems that don't have IPP support.)

It is about perl 5.10.0, which is long overdue for making it into the tree (never mind just into an overlay). You want to upgrade to perl 5.10.0 on an experimental/testing box? Or do you need perl 5.10.0 for a production environment? Its an upgrade. New features. I want it. Others are already using it. Wah! '-) Seriously, 5.8 is being deprecated. Perl6 is what is experimental. Just check what distros have perl 5.10 and which don't. It doesn't look good for Gentoo! [8] Bad form to reply to myself and change the subject, but for anyone who *does* happen to care, a postscript. '-) There doesn't *appear* to be a plan to move perl-5.10.0 into the tree any time soon, but there are plenty of requests on b.g.o. My experience was after fixing the ebuild from the perl-experimental overlay to remove a call to non-existing command-line patch file and just emerging it, perl-cleaner didn't work well for me. Neither does g-cpan, it *seems*... anyway, these are just utilities for managing the perl installation, not *really* needed... So after re-emerging all the modules with some shell scripting, everything strictly perl-ish, catalsytframework included, worked fine. Yeah! OTOH, in the gentoo tree area, it broke emerging perl-tk and inkscape... :( After a lot of googling, I sent related links for reference, two ebuilds and some patches to b.g.o. as now everything on this system installs and plays nicely with perl 5.10.0. I hope it saves someone some time and gets us closer to current perl. If anyone else wants to try it, but runs into these show-stoppers, the (possibly) needed bits are all up there. Worked for me. '-) As far as slotting the perl 5.8 and 5.10 ebuilds, I have no idea if they will. Anyway I think it's traditional to have different versions of perl on a machine, since you just call from /usr/bin/perl and it actually just points to the symlink for the perl you want, so it should be dead easy. But then emerge empties the old perl binary and modules from the 5.8 tree, so who knows... is still the question, I think. -- |\ /|| | ~ ~ | \/ ||---| `|` ? ||ichael | |iggins\^ / michael.higgins[at]evolone[dot]org
[gentoo-user] Re: Keyboard layout switching with Alt+Shift

The generated Command is: setxkbmap -option grp:alt_shift_toggle It works fine in KDE 4.1.3. It even generates the same Command. Furthermore, loading the KDE 4 keyboard layout applet in KDE 3 works and I can switch with Alt+Shift. The KDE 3 one doesn't. What am I missing? I can't directly answer the KDE related question, but I do it like this in my /etc/X11/xorg.conf and it works fine either in Fluxbox, or in KDE (with Fbx as the WM): Section InputDevice Option XkbLayout gb,de Option XkbOptions grp:alt_shift_toggle,grp_led:scroll,compose:menu Thanks for the tip, but unfortunately it doesn't really do a nice job. It enabled alt+shift switching but changes the layout globally instead of just in the application that has focus, I don't get a tray icon that tells me the current layout and shortcuts (like CTRL+C/V for copy/paste) stop working when not in a latin alphabet layout (I use us (English), de (German) and gr (Greek) as layouts). I also posted in the KDE list but no one knows how to fix this :P
