Drupal Search Module errors with php includes
We have been experiencing intermittent Drupal White Screen of Death's when using the Search Module.  At first, we thought it was multiple search terms that were causing this. But, even single term searches would fail.  It seems that it depended on the word being search, but I couldn't make a correlation.

I looked in error_log and it was showing a 500 error.  php.log was showing "PHP Fatal error:  Cannot redeclare mymail() (previously declared..."

I renamed the function, but I got the same error again for the new function name.

Script to create jpg thumbnails from flv files using ffmpeg

Using instructions from Using ffmpeg to create jpg thumbnails from flv files,

I created a bash script that would take a filename from the command line, then output the file with a .jpg extension.

The command line that was given in the post didn't work for me:
ffmpeg -i video.flv -an -ss 00:00:03 -an -r 1 -vframes 1 -y %d.jpg

But, the one given in the comment by Philippe Maegerman did (-minus the .exe part):
ffmpeg.exe -i stream_1146848749371.flv -y -f singlejpeg -ss 0.001 -vframes 1 -an test.jpg

I just modified it to suit my needs.

Some SunRay clients show 14D
Every once in awhile, some SunRay clients will stop being able to connect to a SunRay session and only display 14D.

Log messages showed:
Oct 27 18:18:39 minsk utauthd: Worker4 NOTICE: SESSION_OK pseudo.00144f6f741c
Oct 27 18:18:39 minsk utdevmgrd[19170]: symlink No such file or directory: /tmp/SUNWut/units/IEEE802.00144f6f741c

According to this article:
The SRSS software creates some directory and files in the /tmp filesystem. RedHat Linux has a cron job cleaning up /tmp daily. After a few days some of the files from SRSS were removed, causing the problem. This can be solved by adding "-x /tmp/SUNWut" to /etc/cron.daily/tmpwatch

Hard drive failure in HP 9100C Digital Sender

About 8 months ago, our HP9100C gave this error:

        HARD DISK ERROR CODE 00000004

I tried many things to salvage the data, including freezing it, but nothing seemed to work.

I came across this forum: 9100C hard drive  and someone was looking for an image of the hard drive, but no one had it at the time.

I was reluctant to give get rid of the machine since the only thing wrong with it was the hard drive, so I kept it around.

Today, I checked the thread and someone posted the image.
