Make sure you typed the name correctly, and then try again error message

Sometimes the Windows uninstall program leaves orphan files after a removal event. Here were the error messages and some background information.

XV for Ubuntu

I just finished installing XV for Ubuntu. At first, I thought it would just be another package to install--i.e. apt-get install xv--It wasn't. The XV version (xv-3.10a) was a little old but it worked for my purpose.

Installation instructions can be found here - http://www.alexx.net/2012/07/xv-on-ubuntu.html

Remove old Ubuntu kernel versions from /boot

I was starting to run out of room in /boot. Had about 10MB of space left. I have been dabbling with Ubuntu for a couple months and I am still learning a lot of its nuances. Seems to be a stable OS and a lot of utilities are available for it.

Determine current kernel version (do not delete this one)
uname -r

List all the installed kernels on your system
dpkg --list | grep linux-image

Find kernels below your current one and remove each one with the following command. Again, don't remove your current kernel.
sudo apt-get purge linux-image-X.X.X.X-generic

Update grub2
sudo update-grub2

Reboot system
sudo reboot

Remove Delta Search features from Mozilla Firefox

I usually use Chrome to surf the Internet but it does not work well (button issue) with one of the Internet radio stations I wanted to listen to. The station (181.fm) worked well with Firefox though. However, I noticed a pesky problem with my "New tab" option. The "Delta Search" homepage was still there when I selected the "New tab" option, and I could not find an option to delete it via the browser. But I did find this page and my resolution was at the bottom of the page. Here's the URL for Firefox users, http://info.delta-search.com/uninstall/firefox

The page also has instruction links for Chrome and MSIE.

magicJack's "No Audio Found" Error Message


I had an issue with my magicJack phone. I could hear it ring and it had a dialtone but I could not dial out or receive calls. As a useful working indicator, I should see magicJack's stock symbol (CALL) on their desktop GUI. Instead, I observed the "No Audio Found" message.  Predictably, I rebooted my PC a couple times but no change. I decided to visit the PC's Device Manager.

I invoked the "Control Panel"=>"Hardware and Sound"=>"Device Manager"=>"Sound, video and game controllers" and then uninstalled the USB Internet Phone by TigerJet driver. Then I physically removed the magicJack device from the computer's USB port and then reattached it about 20-30 seconds later. Its driver was automatically found and re-installed. Now I could see magicJack's Stock Symbol: CALL on their GUI. At any rate, it works.

I never had a issue before but I think I had a conflict with another recently installed USB device.

Of course, you might get this error and it's something else. This is what worked for me.

By the way, the OS name is Windows 7.

How to Exclude a Directory for TAR

I am doing a few aesthetic upgrades, so naturally I want to backup some of my website files. However, I do not want everything, i.e. transient files such images. I tarred up the website's primary directory but excluded its images sub-directory.

Frankly speaking, I did not want to waste time and bandwidth downloading images. Here is the syntax to exclude a directory.

# tar cvfp mytarball.tar /mypath/Example.com_DIR --exclude=/mypath/Example.com_DIR/images

Tar everything in the current directory but exclude two files

# tar cvpf mytar.tar * --exclude=index.html --exclude=myimage.png

Restore MySQL Database via Command Line

This is mostly a note to myself. It is not really a tip.

Restoring a mysql database from the command line.

Sun StorageTek 6140 Cache

We have a Sun StorageTek 6140 Array attached to a couple NAS heads. We share out its file systems from the NAS. But it seemed the NAS was creating bottlenecks and hanging NFS. As usual, it turned out to be something else.

We observed slowness during high or bursty I/O operations. Short story...It was the 6140's cache. Make sure your cache batteries are good to go and up to date. They have a 3 year shelf life. It will save you a lot of frustration in the long-run.
