workspace selection by app?

by Bill Mills-Curran

Is there a way to have an application start in all gnome workspaces? For my particular need, I am using xmessage to inform me of specific events on my machine. To make it harder to lose track of the xmessage (pop-up) window, I'd like it to display in all my workspaces. I figure there's some magic setting in gconf (or, even better, an X display setting), but I can't find any documentation on it. Any ideas? Thanks, Bill

LVM snapshot questions.

by Adam Keck

Hello All, I have several questions about LVM snapshots. o Are snapshots persistent across reboots? If not by default, can they be made to be persistent? o How many snapshots can I have at once? o Is there some in-depth documentation out there on just the snapshot aspects of LVM? I spent about an hour googling for this info, but couldn't find what I needed. Why am I interested in this? Last year I took advantage of one of those occasional Tiger Direct ( shameless plug ;) deals to get myself a 200GB drive for 50 bucks. I am using the drive to backup my machines. Right now I backup once a month by copying the user data from my iBook, my wife's iMac, and my Knoppix laptop to the drive. Each time it comes to about 15GB total. I am beginning to fill the drive, so I want to design a more efficient way of using it with OSS tools. My plan is this: o Acquire a cheap used PIII pc. Install the 200GB drive and Centos (for familiarity's sake, RHEL is one of the distros I use at work) o Make an LVM partition on the drive. o Designate half the drive to data and half the drive to snapshot space. o Rsync every machine weekly. Prior to each rsync, snapshot the drive. o Keep as many snapshots as will fit. Presumably this will be many more "full" backups that I can hold than by just copying stuff to the drive outright. I am downloading Centos right now to test this scheme. I thought I would ask while I wait for bit torrent. Has anyone tried something similar to this? -Adam

Re: Wlug Digest, Vol 23, Issue 4

by joel d

Hi, Based on one of our post-meeting pizza discussions last night I thought I would send an e-mail (something I do so rarely). Here is a site that has a good selection of WIFI gear (APs/amps/antennas). I have never ordered from them but they appear to have a good selection of radio gear. http://www.fab-corp.com/ A few ideas to remember: 1) A stronger omni directional antenna (greater db numbers) will improve both your transmit and receive and both are important for range for WIFI. 2) Directional antennas must be aimed at the other radio. You get more gain, but they are usually not the solution if you want to wander your house/deck/yard with the laptop. 3) Amplifiers have downsides; 1) another device to power 2) another device to fail later 3) a good one runs around $200 with both transmit amp and receive pre-amp. 4) Antennas are rated in decibels (db). Most antennas on access points are round 3db - 5db. In terms of signal strength an increase of 3db is a doubling of effective power (Ex 3db to 9db is roughtly 400% stronger). 5) The weakest link in WIFI is usually the card and particularly the internal antenna in the laptop on the far end. 6) You do not succeed unless both devices can both "transmit" and "receive" the other radio. 7) Selection of a feed cable for an external antenna is VERY important. At 2+ghz frequencies a long cable (>1 foot) or a poor quality cable will loose everything you are trying to gain with a better "numbers" antenna. >From a local computer AND radio geek, Joel Desrochers

Reminder: Upcoming Meeting

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, We have a WLUG meeting scheduled for Thursday, Sept. 15 at 7:00 PM in the Access Grid room at WPI. I'm not sure of the topic, but if nothing better turns up, I'll start babbling about my most recent USB experience (which started unpleasantly but ultimately had a happy ending), and we can segue from there into whatever topic people wish to discuss. Bring your Linux problems and try to stump the audience. :-) I'll bring my iAudio G3 MP3/Ogg player since a couple of people said they wanted to see it. I had hoped to have it at the last meeting but it wasn't shipped to me in time. Naturally, we'll go out for pizza after the meeting. We can discuss the insanity of looting televisions during a flood crisis, the possibility of adding anti-DRM language to GPL v3, and whatever else we find interesting. See ya then!

Re: [Wlug] SuSE dual [core] frustration.... - update

by Adam Keck

Hi All, I am having much better luck with the SuSE kernel-smp-2.6.11.4-21.8 kernel. The dual core machine boots normally (i.e. without maxcpus=1) and /proc/cpuinfo shows the four cores. Unfortunately, the SuSE's (9.3) particular iteration of the forcedeth module seems to be having trouble with the networking bits of the nforce4 SLI chipset. Rather than dipping into the SuSE kernel-of-the-day development builds, I think I am going to drop in an Intel NIC in order to move forward. I will send an update when we put the machine through its paces. -Adam p.s. I just found a shrink-wrapped Maxell Mammoth cleaning tape and an upwrapped unused Compaq DLT IV tape in a moving bin. I don't need them anymore. I will let the DLT IV go for 15.00 and the cleaning tape go for 5.00. Email me off list if you are interested. I can bring them to the Sept. meeting.

I've been playing around with my MP3 player and trying to make it work on my server. It works fine on my laptop. The MP3 player is a usb_storage device (iAudio G3). I didn't hack any drivers, nor have I ever. I had thought that perhaps I could start a discussion of this topic, where folks would kick in their 2 cents worth, and collectively we'd come away with more knowledge about using Linux and USB. Its just a thought - I'm not sure anybody is interested, or perhaps this is old hat to most of you. Since we have an upcoming meeting on Sept. 8th, I'm looking for ideas, and thought this might be one.
