RE: [Wlug] reaction-diffusion program

by Steve Freitag

Here are a couple of things to check: - XAllocColorCells works with a PseudoColor visual. You may be running in TrueColor. Use xdpyinfo to find out. (grep for Color) - If you are in PseudoColor mode, you might not have enough free colors left. You might want to start a plain X session (no netscape etc) with a window manager like fvwm or twm. If you are familiar with vnc, you can start a vncserver in PseudoColor mode using the -cc 3 option. You may also want to modify xstartup (in your .vnc directory) to invoke a simpler xinitrc which starts fvwm or twm. -----Original Message----- From: wlug-admin(a)mail.wlug.org [mailto:wlug-admin@mail.wlug.org] On Behalf Of Gregory Avedissian Sent: Tuesday, March 04, 2003 11:43 AM To: wlug(a)mail.wlug.org Subject: [Wlug] reaction-diffusion program I'm trying to run a reaction-diffusion modeling program.

I think that's a limitation of my vid card if I remember correctly. Anyway, there was no difference. I get a quick flash like a window is opening, then it disappears and I get the error message.

Re: [Wlug] Samba shares

by Michael Long

It turned out that there was a file that was a soft link to another in that directory. I guess that that confused windows. I would have expected windows to copy all but that linked file, but nooooo!!! it had to fail with a very nondescript error that was useless. <sarcasm>I just love windows</sarcasm> Mike > on the linux system checkt he permissions of the sub directories.. > Have read and execute permmmisions? > > On Tue, 4 Mar 2003, Michael Long wrote: > > > > > I have a directory which has been shared out using samba.

Samba shares

by Michael Long

I have a directory which has been shared out using samba. I now need to move some of those files including subdirectories to a windows box running windows 2000 server. From the windows box I can copy files from the samba share but the subdirectories on the samba share fail to copy. Is this a samba issue or a winblows issue? Any help is appreciated. Thanks, Mike

reaction-diffusion program

by Gregory Avedissian

I'm trying to run a reaction-diffusion modeling program. Below is the link to the tarball. I was able to install it after editing the makefile (added -LX11R6 to the LIBS section, per generic instructions I found on a google search for the error message I got when make failed.) Here's the current problem: When I try to run the program with the sample parameters given in the readme.txt, I get the error message, "bad status from XAllocColorCells Segmentation fault" Note: I get occasional segmentation faults, possibly due to a flaky power supply. Those seem to be less frequent since I vacuumed the dust and cat hair out of the box. Here's a link to the tarball, in case anyone has the time or inclination to mess with it and/or offer advice.

shared calendar (web-based)?

by Bill Mills-Curran

I have some guys I work with who would like to be able to use a web-based tool to help schedule ping-pong games. Part of the requirement is that the players don't always have a partner and they would like to advertise available times so that someone else is encouraged to arrange a match with them. I already have an old web calendar program, which works, but I'm not very enthusiastic about it. Does anyone have a recommendation of a web tool that will work? FYI, I'm running Red Hat 8.0.
