Can’t find out how to turn on the seek bar in VLC Media Player in the Full Screen Mode?

Close VLC Media Player and then Delete the vlc folder in your %appdata% (Delete C:\Documents and Settings\username\Application Data\vlc)

Optionally you might also try to Reset Preferences. Tools menu > Preferences > Reset Preferences > Save (Did not work for me.)

I’ve been using Synergy for quite a while now and I find it extremely useful.  I’ve demonstrated how I use Synergy and simplified my life by keeping the monitors and using one keyboard and one mouse across different computers.

What I’ve done, is used my primary KB and Mouse across my Win-XP Laptop, Win-XP Desktop and Cent OS (Linux Box). So, I installed Synergy on all computers and  configured Synergy with my Win-XP Desktop as the server and the clients which are my Laptop and Linux box share the server’s KB and mouse.

Setting up Synergy is pretty simple. Configure the server and let it know what machines are on it’s left and what machines are on it’s right. For instance

• Win-XP Laptop is to the Left of Win-XP Desktop
• Win-XP Desktop is the Right of Win-XP Laptop
• Linux Box is to the Right of Win-XP Desktop
• Win-XP Desktop is the Left of Linux Box

Start up your Synergy server and Synergy clients and thats it! What I also love about Synergy is the ability to copy, paste between computers. Yes – RDP does it too, but again if you want to use other monitors and share the same KB and mouse then this is really fantastic. It’s a really cool tool.

If you’re wondering about .pssx file extension – it’s a presentation saved using Powerpoint 2007.
To open it simply download the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats and install it.

Then, Right click on the Document to open, Select Open With… and chose Microsoft Open XML Converter to view the contents of the file.

You can use sed to edit the contents of a file (say, replace ‘old_str’ with ‘new_str’ in the file default.properties and send the result to default.properties.bak).

sed ‘s/old_str/new_str/g’ ./default.properties > ./default.properties.bak

The script below uses the eval command to use variables with sed.

#!/bin/sh

FIND=’old_str’
REPLACE=’new_str’
FILE=./default.properties

eval “sed -e ‘s/$FIND”/”$REPLACE/g’ $FILE > $FILE.bak”
mv -f $FILE.bak $FILE

For more information on sed read sed – An Introduction and Tutorial.

Let’s say you have a tar.gz file. For example, apache-ant-1.6.1-bin.tar.gz

# Decompress the zip file
gzip -d apache-ant-1.6.1-bin.tar.gz
# Extract the ant files in verbose mode
tar -xvf apache-ant-1.6.1-bin.tar

To capture tcpdump output

tcpdump -v -s 4096 -w capfile.cap port 25

You can then read the capfile.cap file using WireShark
