Re: Help re-installing/restarting Xinerama
by Jonathan Hutchins 10 Feb '05

One of the reasons for confusion on this seemingly obvious question (where's the conf file) is that those of us who've been running X on Linux for a couple of years have been through some changes. Even before the transition to XFree86 v.4 there were occasions where more than one conf file was involved in a sort of cascading effect. Most distros seem to have gone back to the single file now, but the practice still appears to be to include a LOT of different configuration options and have X sort out what works and what doesn't. My curent file, for instance, is unusually simple and only has four mode sections - only one of which works. A while ago I embarked on a quest to get my system running in 100dpi mode instead of the default 75dpi. I found many places where the setting was available, but none of them affected my actual X sessiosn at all. I eventually gave up on it - it doesn't really seem to matter anywhere except when printing graphics. I'm sure more than one of us anticipated a far more complicated problem, and did not trust the simplicity of the obvious answer. Hopefully Leo will let us know if we were wrong.

Actually the course also had some mountainous terrain, and yes at least one vehicle went over the edge. I was only partially kidding. On the sonar, I was actually recommending lasers for that task. I realize some use sonar, but I feel lasers are better suited, due to the resistance to added noise. MIT's car can successfully track the lines in the road. So that milestone would be easy to add on to. MIT's car had the bad habit of taking *every* off ramp. The problem isn't so much about being able to read the lane markings, but being able to realize that the lane markings are changing, such as an upcoming off-ramp, or have disappeared entirely. Hence it is better to have a system that can track the road edges, and/or traffic on either side and only use the painted stripes as a general guideline . I think that a system could be successfully built to handle the piano falling off the moving truck. The DOD doesn't care about that. They want to drive heavily armored <insert doomsday vehicle of choice here> over terrain of varying complexity to reach the objective target and take out the bad guys while ensuring it doesn't contribute to "friendly fire". You can add my thousands of hours of thinking about and designing autonomous vehicles to your thousands of hours and the millions of hours of other people. ;') It's a fun challenge. I think it's doable with the PC hardware and technology we currently have. I just haven't had the time to build a prototype to start training. I disagree that it would be easier at night. At night you have to add all the moving lights that may affect sensors in unpredictable ways. I think you'd just be trading on set of noise for a different set of noise, but it does bring up the point that the system needs to be able to transition from one to the other smoothly. > -----Original Message----- > From: David Nicol > > I realize you are kidding, but I spent thousands of hours in the early > nineties thinking > about automating driving in cities.

I'm running Mepis on all my boxes except my webserver and firewall. Which are running "stable" versions of debian. I've been very happy with it. Maybe the reason it is so popular is a sign of. Mepis is now the 4th most popular distro, running very close behind SuSE. Mandrake still holding the top tier, anyone know if they've ever fixed the broken updating feature in Mandrake? Anyone out there still using Mandrake or Fedora/RH? > -----Original Message----- > From: Richard A. Franklin > > Brian Kelsay wrote: > > > Glad you like it and maybe found a keeper.

I think I got the older IceWM, and would like to try the experimental over the weekend ... it might be a bit less "gritty" ;-) I did add all suggested packages for IceWM from the pre-install list while having my "apt-fest" last night. Mepis is a nicely polished distro, deserving of some kind of contribution. It may very soon end up on my more serious home office desktop, even though SuSE has been a good choice. For the road, do you have any experience with Mepis for re-sizing NTFS partitions for a dual-boot? Or maybe I should just leave my poor old laptop alone ... it is working fine right now! Rick

Glad you like it and maybe found a keeper. I just installed the newest stable version of Mepis (2004.06) on a desktop system so I could stop running from CD. I also plan to test the latest test release on the same PC and compare. It's worked well for me. Some things can be difficult installing due to the apt-pinning, but you can get help from other Debian users and on the Mepis forums and IRC. When you used apt-get to install IceWM, did it get added as an option to the login screen? There is some nice automation in Debian systems like apps being auto added to the K menu in KDE after an apt-get. I don't have to restart for a rescan of apps or anything, they just appear. Save your LiveCD of Mepis in case you fubar your X config or GRUB. Brian Kelsay >>> "Richard A.

I have used IceWM with VectorLinux, so I used apt-get to install all related packages. Also, "apt-get install streamtuner" (!) Like you say, "fast and easy". IceWM is much faster than KDE, but clunkier ... certainly much less polished, but I suppose that's the trade-off if I don't want the bloat. Rick

Open Source Values
by Jim Herrmann 04 Feb '05

04 Feb '05

I've been reading George Lakoff, and doing a lot of thinking about values, lately. My own values as well as those of others. I know what it is about open source software that appeals to my values. You can look at the list in my sig and get an idea of the values I'm talking about, and you can imagine how OSS fits into them, but I don't want to bias the discussion too much beforehand with my opinions. I will offer those up later. What I would like to know from some of you guys is, which of your values are best served by OSS? Please let me know either directly in confidence, or publicly to the list, where you consider yourself on the conservative/moderate/progressive political spectrum, and what it is about OSS that appeals to you. I'm especially anxious to hear from my LUG friends on the right of the spectrum, as that is more difficult for me to understand. Once I've heard several opinions, I plan to formulate some kind of summary explanation, or theory, that connects different values and the open source movement. Thanks for your input, Jim Herrmann -- Progressive Values ARE American Values Responsibility, Empathy, Freedom, Opportunity, Prosperity, Fairness, Trust, Honesty, Open Communication, Community, Cooperation

Phpnuke question
by kurt＠verruckt.org 04 Feb '05

04 Feb '05

I am installing phpnuke on a site that I am working on, and having trouble configuring the config.php file. For the dbhost should I just be putting the IP address of the server itself? Or IP/~username ? I have tried both the dbname as "dbname_nuke", and just "dbname". And the same formats for the username. No matter how I try it, I continually get an error that it cannot connect to the MySQL server. I KNOW the database is there, because I created it. All the permissions on the directories and files are exactly as it calls for in the install docs. I am using nukesql.php to help with the install. Any db gurus know about phpnuke installs? Would appreciate it. Kurt ---------------------------------------------- Si hoc legere scis, nimis eruditionis habes. --- Outgoing mail is certified Virus Free.
