comment 32 bit appplication on 64 bit linux not working
Don't use force. apt was trying to prevent you from making a mistake, and you thought you knew better than it, but you didn't.

comment Problem with find and variables
Why are you using fIn[1] and fIn[2]? What do you think that gives you that using properly named variables like fn=$1;shift;pattern="$@"?

comment cron, every minute ram issues
I believe there is a race condition if another process creates the /tmp/wordpress-job.pid in between the test and the echo. A safer way would be to create a /tmp/wordpress-job.$$ file, and then attempt to create a hard link to /tmp/wordpress-job.pid - the link will fail if /tmp/wordpress-job.pid already exists, and it's atomic.

comment top output: cpu usage > 100%
Also, I see you're using compiz. Do you have a good 3d graphics card? If not, that's probably where all your CPU is going, trying to render a movie onto a 3d surface.

It's not lying to you, because your load average is up over 4. That seems high - try restarting vlc, and do something to free up some memory first.

comment ~ is $HOME, but sometimes?
It's not the kernel or the "cd executable" (since there is no such thing) - it's a shell built-in.

comment Why does the “du” command count in 4KB steps?
4k is the size of a single disk block. Disk space is allocated in blocks, so even the smallest disk takes up one block (4k) on your disk.

comment Chmod u-x isn't changing anything and I have no idea why
Oh, and "ls -ld ~" couldn't hurt either to see what the permissions on the home directory are.

Do an "ls -ln" and an "id" to see if the uid of the "eulerz" who owns the file and the "eulerz" who is logged into the machine is the same.

comment Should I use LILO or GRUB or other?
GRUB is a great flexible boot loader, but most of the flexibility goes away on a WORM media like a DVD.

comment Alternative for `sleep seconds` that takes system load into account?
The "sleep to give the server time to get ready" is a really really bad idea. It would be far better if your client and server were both robust enough to handle the case where the other end isn't ready to talk to them, using retries or whatever.

comment cron is ignoring MAILTO
Can you send email to that address from the command line (ie using "mail user@hostname")?
