Create a Simple Reflective Text using Inkscape for Web
In the quest for finding a good Open Source software for my web works, I came across this wonderful software called "Inkscape" (http://www.inkscape.org - Version 0.46) - Inkscape is an Open Source vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format. Before this I use Adobe Photoshop to create this simple reflective effect. This tutorial is to use Inkscape to create the simple transparent reflective text - to PNG format.
Workaround for Symantec Endpoint Protection VirusDefs issues
At the office, we are using the Symantec Endpoint Protection (corporate edition) anti-virus solution. One day we realise that every computers running Windows XP Professional in the office is having an issue with low disk space. After a details check-up we found out that the Symantec is storing all the virus definition updates in the "C:\Program Files\Common Files\Symantec Shared\VirusDefs\" folder and it will never gets deleted ! most computers will have at least 20-40GB alone in that folder. The workaround is by using this simple MSDOS batch file to actually delete all the TMP files in that folder.
Using Margin in HTML

Using Google Calendar
Google has introduce a very nice tool, the Web Calendar. It's online, you can access it anywhere as long as you have the internet access, and it's quite handy been able to add,view and update it anytime convenience to you. Another good feature are, you can actually share your calendar with your family and friends - of course you can set what others can see and what they can't see.
Prompt shell: Simple way to rename multiple files
The situation is you have a number of files with sequence filenames, and you would like to rename it, for example you would like to rename from photos01a.jpg to photos01.jpg, yes, it just a simple removing the 'a' from it, but it would be an annoying jobs if the number of files is quite big.
Basic Home Broadband setup
With the broadband coverage is now widely available, more and more people are started to setup small network at home. Dad have their own PC, mom using the laptop with wireless G and kids learning and accessing the internet using wireless.
Prompt shell: Basic sed command
sed stand for Stream EDitor. It is more to ascii text manipulation, but this time while it's from the command line instead of in the text editor like vi. The replace command looks exactly as the vi editor replace command.
Prompt Shell: Modify and execute previous command
Been long time since I used this command, only today I had a chance to try it again, and to my surprise it still works ! Previously I use this under SUN Solaris unix, it still works when I tested it on FreeBSD 5.x.
Shell prompt: Basic find command
In windows environment you will just have to open the search window, input what you want to search/find and then click the search button. In unix/linux environment, if you're using the X windows system, you might have that capability, but for a faster action, I always prefer the terminal/shell prompt.
Shell Prompt: Basic Links
Links is a way to replicate a file and share it with other users (of course with a proper permission applied). Any changes made to any of the link files, all will be affected. This was used last time during software programming development on unix (and yes that will be >10 years ago, vi is the best editor and cobol was widely used).

Shell Prompt: The while loop
Another looping command that you can use in command prompt is while loop. Used to be my favourite while waiting for some process to finish - usage to monitor that on-going process, as I hate waiting without knowing whats going on - eg. how much records has been transferred etc. etc.
Shell prompt: Resetting the Backspace key
Sometime when using Telnet Terminal program from Windows or from some other servers, the Backspace key will display ^H instead of deleting the previous input. Don't really know what exactly causing this, maybe due to the terminal setting of the client Telnet program or something else (would love to hear if you do know what cause this behaviour).
General: The invisible/control character
This used to be the trick to hide folders in unix last time (not sure whether it's still been used nowadays). Sometimes even the GUI file manager can't go into the folders due to this unprintable control character.
Vi Editor: command repetition
Another useful feature in vi editor is you can specify how many times you want the command to be executed and it's applicable to almost all the commands.
General: Getting to know awk
awk is quite useful when you need to filter your output. As a start I will demonstrate a simple usage of awk.
Shell prompt: The for loop
Tested on Bash shell.
Sometimes we might require some looping process in our daily system admin job. Example below is just one of many usage that you can do with the for loop on shell prompt.

In this small section we will try to show you the most out of tar command.
