If you are not currently using screen on a regular basis you should start. The Linux screen application allows you to keep remote sessions active even when you disconnect from the server via SSH or similar.

Ubuntu Linux Apache Error: [notice] child pid XXXX exit signal Segmentation fault (11)

I received the below error when troubleshooting an issue reported to me by a client regarding one of their intranet web sites not working properly. After some poking around I noticed that there were numerous segmentation faults being reported in the Apache error logs. I had previously set up the server to dump core files when there were segmentation faults within Apache so troubleshooting the error was fairly easy.

Restart Paste Master without restarting Mac OS X

I use Paste Master as an advanced clipboard manager. It allows me to keep up to 90 items in my clipboard and also allows me to paste them unformatted so I don’t have to copy them to an ASCII text editor first. It would not come up one day and wanted to restart it without the OS (operating system). Under System Preferences, uncheck and check “Enable Paste Master” and that will restart it. Since it is a checkbox, it might appear to only take effect when the OS restart, but it takes immediate effect.
