Let's make WLUG meetings better!

by Andy Stewart

HI everybody, I was a little disappointed at the turnout from the last WLUG meeting. We had 8 or 9 people show up, and while we did have a good time watching Scott and Doug get a couple of scanners working under Linux, it would have been alot more fun with more people in attendance. I believe this was the lowest attendance we've seen at a WLUG meeting in our 5.5 year history. :-( We discussed possible reasons for the low attendance at the Boynton over a few beers. One suggestion was that I should update the WLUG website to show what we have done at past meetings so people wouldn't think that nothing was accomplished. I've done that and will endeavor to keep that part of the WLUG website current (see "Past Meeting Information"). Another thought was that some people will only come to a meeting if the topic looks interesting to them, and if it is announced well in advance. I must admit to having been somewhat lax in that area lately. Therefore, in an attempt to remedy that (at least for this month), I'm putting out the call now for a speaker and a topic for the Dec. 12th meeting (its coming up fast!). I sent out a list of potential topics last month, but I know that there are a zilliion interesting things happening in the Linux world that could be discussed at a WLUG meeting. The meeting need not be discussion based, either! Although Kinnicutt Hall lends itself well to this type of meeting, we do have access to other rooms on campus. People have tossed out ideas such as these: o build a network for multiplayer Linux games o build a network to see if WLUG crackers can break into your system (not to destroy it, but to teach you what to fix to secure your system) o more live demos! The group exists to meet your needs, so please, state your needs! I can't arrange a meeting to your liking if I get no feedback on what you want to see at future WLUG meetings. More importantly, I'd like to see more and different people volunteer to do the presentations or to run a live demo. If you look back at the last year of WLUG meetings, you'll see the same names many times. While I'm *quite* happy that these folks continue to volunteer, I'd like to see others jump in also. Finally, if anybody has feedback regarding the last meeting and why it lacked attendees, please bring it up on the list so we can all discuss it. Without such candid discussions, WLUG cannot improve.

Re: [Wlug] more alphabet soup :-(

by Robert L Krawitz

I wound up not buying a DVD writer at all. Micro Center had a Buslink 48x12x48 (which when I opened it up turned out to be a 48x24x48) for $20, and both Micro Center and Best Buy had really good deals on CD-R's. I'm nervous enough about the mess of formats that I don't feel like spending $300 on something that might be completely worthless in 6 months. CD-R's have been around a while and are completely standard. At that price, I'll put up with the inconvenience. If I use gzip rather than bzip2 compression, I think things will be fast enough so that backups won't be that much of an annoyance. -- Robert Krawitz <rlk(a)alum.mit.edu> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf(a)uunet.uu.net Project lead for Gimp Print -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton

more alphabet soup :-(

by doug waud

Hi again Just got the latest PC Magazine and I note that my table of CD/DVD acronyms (plagarized from PC World) is already out of date. :-) Now we have CD-MRW where the M refers to Mount Ranier. Although "there have been no specific announcements of DVD+MRW drives yet, Phillips recently proposed an addition ... The Sony DRU-500A apparently ships with Mount Ranier. (The Mount Ranier format put a Main defect table in the Lead-in area (area outside the data area) and a copy of the defect table in the lead-out area.It also sets aside some space in the data area as a "replacement area" where date which would have landed in a bad block is put. The price is somewhat slower reads/writes and slightly reduced capacity. The gain is reliability. Non-MRW drives will need custom software to read MRW data.) doug

They do note that "DVD-RW format leaves disk formatting up to the software .... must perform a full disk format --- which can take an hour --- before you can start writing to the disk". Perhaps they feel this investment of time is beyond the attention span of those who watch TV. :-) I can also speculate that the ability to rewrite the DVD-RW may have tipped them in favor of it for data. Perhaps all that we are seeing is the problems that arise when you try to force data into a tabular format. :-) Take your pick/and-or make your own guess! doug

quota on RH 8.0

by Aramico

Hi All, I've got a problem here..... On RedHat 8, I tried to implement quota. I have created the aquota.user on / and the other define directory. ..and I have reconfigure the /etc/fstab and wrote the tag in order to enable the quota. When I'm tryin to run quotacheck -avug, there is a notifications as shown bellow : quotacheck: WARNING - Quotafile //aquota.user was probably truncated. Can't save quota settings... quotacheck: WARNING - Quotafile //aquota.group was probably truncated. Can't save quota settings... quotacheck: Cannot remount filesystem mounted on / read-only so counted values might not be right. Please stop all programs writing to filesystem or use -m flag to force checking. what was wrong here ? can somebody tell me how to implement the quota here ? I want to know the diffrence to the thing that I've done. Thanks.

That PCWorld article I mentioned earlier in this thread has a nice table. The first step is to note that there are three pairs: DVD-R and DVD-RW DVD+R and DVD+RW CD-R and CD-RW plus one single, DVD-RAM which (so far) has no RW sibling. (I include CD's to emphasize the pattern) That article also has a table: Type Can be written to by drives of type DVD-RW DVD+RW DVD-RW/+RW DVD-RAM/-R/-RW DVD-RAM/-R DVD-R yes no yes yes yes DVD+R no yes yes no no CD-R yes yes yes yes no DVD-RW yes no yes yes no DVD+RW no yes yes no no DVD-RAM no no no yes yes CD-RW yes yes yes yes no and with same rows: Capac Cost Cartrige? Quick Format Data verifn 4.7GB $4 no n/a no 4.7 5 no n/a no 700MB 1 no n/a no 4.7 6 no optional no 4.7 7 no yes no 4.7* 15 yes** n/a*** yes 700 1 no no no and still with same rows: Defct Mngmt Max Rewrites Seq/Rand Data/video? no n/a seq video no n/a seq video no n/a seq video & data no 1000 seq data yes**** 1000 seq data yes 100,000 random data no 1000 seq data * double sided gives 9.4 GB ** disks also available w/o cartridges on a spindle *** DVD-RAM disks are preformatted **** only on Mount Ranier writes which are not supported by most drives Hope the formatting survives! :-) doug

From: "Keller, Tim" <Tim.Keller(a)stratus.com> Date: Mon, 25 Nov 2002 12:48:44 -0500 Well the next question is... What do you want todo... The cross post in question wants to backup large amounts of data. I would think a drive that could do DVD-RW or DVD+RW would be their choice since they could setup some sorta rotation. As for supported drives you'd want to check the cdrecord website. Actually, I *don't* want to set up a rotation. I want permanent, long-term storage. These things are pretty cheap now ($5 or thereabouts); 2-4 of these per month, plus maybe one more for weekly incrementals, isn't going to bankrupt me. Now, if you want to make backups of the DVD's that you own, or convert the VHS you've got into DVD, you'll also want a drive that can author DVD disks. However you'll want to check a site like www.vcdhelper.org they've got a good matrix of what different disks DVD players supports (such as VCD/SVCD/DVD-R/DVD-RW/etc...) Personally, I'm too disgusted at the entertainment-retail complex to really even want to bother with these things in the first place (left to myself, I wouldn't even bother owning a TV these days). -- Robert Krawitz <rlk(a)alum.mit.edu> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf(a)uunet.uu.net Project lead for Gimp Print -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton

However this was using a mix of freeware windows utilities and Nero, I'm pretty sure that that the cdrcord-prodvd utilities it would work fine. Later, Tim. -----Original Message----- From: Brian J.
