reboot problem
by Gregory Avedissian 18 Dec '07

18 Dec '07

At the meeting before last, I asked about a problem I'm having with the computer occasionally going to a black screen with no disk activity on reboot, right after the grub menu goes away. Overnight memtest showed no errors, I put a different vid card in, and still had the black screen problem. One of the things someone mentioned was to test the power supply. Recently, I had a few hard lockups and a couple of spontaneous reboots. So, how do I test my power supply, other than replacing it and seeing if the problem goes away? Or is that evidence enough to change it ASAP? According to lm-sensors, voltages are fine, and I've even sat and watched gkrellm for long periods of time - they look stable. Any suggestions would be appreciated. Greg

Any XMl-types out there?
by Stephen Daukas 04 Dec '07

04 Dec '07

Hello Everyone! So, I have to teach myself myself XML, XSL, et al., for work... (The VB stuff is in the background for now!) I started playing with XML yesterday, and have gotten pretty far along. But... I have to deal with M$-generated XML files that looks like the following (I added the first two lines for display in a browser): <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="SOURCES.xsl"?> <xml xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882' xmlns:dt='uuid:C2F41010-65B3-11d1-A29F-00AA00C14882' xmlns:rs='urn:schemas-microsoft-com:rowset' xmlns:z='#RowsetSchema'> <s:Schema id='RowsetSchema'> <s:ElementType name='row' content='eltOnly'> <s:AttributeType name='ID305B' rs:number='1' rs:nullable='true' rs:maydefer='true' rs:writeunknown='true'> <s:datatype dt:type='string' dt:maxLength='50'/> </s:AttributeType> [snip] <s:extends type='rs:rowbase'/> </s:ElementType> </s:Schema> <rs:data> <z:row ID305B='MA11002' CYCLE='2002' USE_ID='537' CAUSE_ID='226' SOURCE_ID='180' CONFIRMED='N'/> [~11,000 lines snipped] So, I wrote the following SOURCES.xsl file to display this beast in a browser (it uses recursion): <?xml version='1.0'?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:rs='urn:schemas-microsoft-com:rowset' xmlns:z='#RowsetSchema' version="1.0"> <xsl:template match="/"> <HTML> <BODY topmargin="0" leftmargin="0"> <xsl:apply-templates select="/xml/rs:data"/> </BODY> </HTML> </xsl:template> <xsl:key name="rows-by-AU" match="z:row" use="@ID305B" /> <xsl:template match="z:row"> <xsl:apply-templates select="key('rows-by-AU', ID305B)" /> <div AU_ID="{ID305B}"> <xsl:apply-templates select="key('rows-by-AU', ID305B)" /> <div USE_ID="{CYCLE}"> <div USE_ID="{USE_ID}"> <xsl:value-of select="@ID305B"/> (<xsl:value-of select="@CYCLE"/>): <xsl:apply-templates select="key('rows-by-AU', USE_ID)"/> <xsl:value-of select="@USE_ID"/> - <xsl:value-of select="@CAUSE_ID"/> - <xsl:value-of select="@SOURCE_ID"/> </div> </div> </div> </xsl:template> </xsl:stylesheet> And it works (surprised the hell out of me)! But now I'm having the hardest time figuring out how to format this the way I'd like. This is how it currently looks in the browser: MA11002 (2002): 537 - 226 - 180 MA11002 (2002): 537 - 448 - 140 MA11002 (2002): 538 - 226 - 180 MA11002 (2002): 538 - 413 - 140 MA11002 (2002): 538 - 413 - 177 MA11002 (2002): 539 - 226 - 180 MA11002 (2002): 539 - 413 - 140 MA11002 (2002): 541 - 226 - 180 MA11002 (2002): 541 - 478 - 140 MA11002 (2002): 541 - 413 - 140 MA11018 (2002): 538 - 413 - 140 MA11018 (2002): 539 - 413 - 140 MA11018 (2002): 541 - 413 - 140 MA11019 (2002): 537 - 312 - 140 MA11019 (2002): 538 - 312 - 140 MA11019 (2002): 539 - 312 - 140 MA11019 (2002): 541 - 312 - 140 [... other IDs in between 2002 and 2008 ...] MA11002 (2008): 537 - 226 - 180 MA11002 (2008): 537 - 478 - 92 MA11002 (2008): 537 - 312 - 156 [... thousands of additional IDs ...] And I'd like the output to look something like: MA11002 (2002): 537 - 226 - 180 - 448 - 140 538 - 226 - 180 - 413 - 140 - 177 539 - 226 - 180 - 413 - 140 MA11002 (2008): 537 - 226 - 180 - 478 - 92 - 312 - 156 [...] So, things would need to be grouped by ID305B and CYCLE, then by USE_ID, then by CAUSE_ID, then by SOURCE_ID. But, I'd even settle for output that looks like: MA11002 (2002): 537 - 226 - 180 MA11002 (2002): 537 - 448 - 140 MA11002 (2002): 538 - 226 - 180 MA11002 (2002): 538 - 413 - 140 MA11002 (2002): 538 - 413 - 177 MA11002 (2002): 539 - 226 - 180 MA11002 (2002): 539 - 413 - 140 MA11002 (2002): 541 - 226 - 180 MA11002 (2002): 541 - 478 - 140 MA11002 (2002): 541 - 413 - 140 MA11002 (2008): 537 - 226 - 180 MA11002 (2008): 537 - 478 - 92 MA11002 (2008): 537 - 312 - 156 [... thousands of additional IDs ...] where the IDs from the two different years are adjacent to one another... I believe this will involve much pain and suffering while I try to figure out such things as XML nodes, grouping, sorting, and the like... But, I'm hoping someone will look at this and say "boy Daukas, that's easy... just do this, and then that, and voila - your done!". Anyone? Anyone? ;-) Thanks in advance for any help! Steve

Solaris automounter

Hi All, At work I have a SunFire v245 (Sparc) running SunOs 5.10, which I guess is Solaris 10. When I put a CD in the drive, it doesn't get mounted. I checked to see if 'vold' was running and it was. What else should I check for? I'm not too familiar with Solaris, so any help is appreciated. TIA, -Chuck

Xinerama issues with Fedora Core 8...
by Tim Keller 21 Nov '07

21 Nov '07

Hey Gang, I had a perfectly working Fedora Core 6 system and I had to go mess things up... I backed up my whole system and did a clean install of Fedora Core 8, only to find that my >old< xorg.conf config doesn't work anymore... I was able to get a config finally working, but only on a single monitor. Here's my setup: Screen 1: DELL LCD panel connected to an onboard AGP intel video card Screen 2: DELL LCD panel connected to a PCI ATI Radeon video card Now, I have config files that'll drive one or the other, but not both. The moment I enable Xinerama, the X server crashes with a signal 11. As far as I can tell... Xinerama support is totally borked in Fedora Core 8. Has anybody come across any solutions? Thanks, Tim. -- I am leary of the allegiances of any politician who refers to their constituents as "consumers".

initrd.img file
by vze284qe＠verizon.net 20 Nov '07

20 Nov '07

Hello, I built a custom "gutsy gibbon" kernel, but I can't find the corresponding initrd.img file. There's a link in / that looks like this: initrd.img-> boot/initrd.img-2.6.22-generic. Shouldn't there be a new initrd.img file that was created when I built the new kernel or am I missing something? TIA, -- -Chuck

Linux Choix?
by Greater Worcester Land Trust 20 Nov '07

20 Nov '07

It has been a while. I tried getting our nonprofit (Worcester land conservation) to adopt Linux some years back. Problem I had back then was weak graphic options, publisher options, Quicken options, and a lack of a good answer to running ArcGIS. I was beaten back into M$. I want another crack at this. I am looking to take a spare laptop and install a Linux OS and OS apps. Previously, some years back, I used to use what are now Mandriva Linux installs. Coming back to this I see that there are dozens and dozens of options these days. What, if any, of the options do the WLUG folk prefer/recommend. Thanks so much, Colin

Can you downgrade the individual driver(s)?

Linux Choix?
by Colin Novick 19 Nov '07

19 Nov '07

Apologies. Deepest even. Before anyone needs to chastise me I looked it up and OS X is more Next and other sources than Linux per se. Apparently Parallels on OS X will run Win and Lin, but the underlying OS is OS X and does not imply that ArcGIS would be stably emulated by a Linux machine emulating Win. Sorry. Hope not to have too terribly offended in my ignorance. Colin

Where the heck is everything? http://tldp.org/LDP/intro-linux/html/sect_03_01.html has a nice chart I think one thing that frustrates people is their relative path to everything...you can't cd /mike unless you're already in /home for instance. Even from the GUI's, Windows people will start at C:\ and move around from there. ----- Original Message ---- From: Kevin Harrington <mad.hephaestus(a)gmail.com> To: wlug(a)mail.wlug.org Sent: Sunday, November 18, 2007 12:01:05 AM Subject: [Wlug] Information for Linux newbies? As i mentioned at the meeting this past week I am going to be giving a seminar for linux newbies and would like to pull from people that know better then i do on what i should teach people. What i would like to know is: What are some things that you wish you had known as a newbie? Think back to your very first linux install and any short-cuts, tips, tricks, and gatcha's that would make peoples first experience easier. There is a lot of windows resentment after the slow trainwreck that is vista, so lets see if we can get a few new converts! P.S. one of the big concerns for a few people that i have talked to has been games, if anyone has a list of new-ish games that work or any tips specific to making the most recent generation work under linux, that would make things much easier ;) _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug
