Did you use windows run command? As a normal user point of view, command and short cut key are very difficult to use, mostly prefer using mouse to click, but when you become a good friend to your computer, command and short cut key help a lot in daily job.

For example, I always like to use ms paint to do some simple editing, to open a paint, I need to click on start button, go to program, then Accessories, only I can found the Paint program there.

Now with using run command, I just require to click start, run, and key in mspaint, then hit Ok

Tips: Some Windows Vista does not have “RUN” button when click on start button, to open run, simply press windows button on your keyboard and press R, the run box will come out already.

Other then this, I experience before few time when looking for some application such as “hyperterminal” in the computer, it does not located in the correct place. If you don’t mind extra step, can go into C drive, one by one folder search, but with using run comand, just type “hypertrm“, hola, it come out already.

I have download Centos 5.2 (www.centos.org) few month ago, also try to install it and experience it, but not much time to really put my self in study on Linux base operating system. After install centos linux base operation system, now I require web server script, Apache, web programming script, PHP, and a database script, MySql. So how to install all this script? I found a easy way to install Linux Apache MySql PHP (LAMP) using Yum command. Just simple 5 step to fully setup your own web server.

How to install Apache using Yum command: (more…)

I am graduate as an Information System Engineer, which suppose to be a programmer at the moment, but I am not, because I was easily bored with those programming language. In the other way, I am very interest on those short command line, such as ms-dos command line.

Ciscopedia , which is a dictionary that have the collection of cisco command line. This Cisco Pedia contain where, when, why, and how to use the cisco commands. Most of the new Network engineer, or begineer who like to learn Cisco Networking Commands must keep this as their weapon especially those CCNA, CCNP, CCIE holder.

In CiscoPedia, the content in this software are very informative, it will shows the command, the mode, the syntax, syntax description, command description, examples, misconceptions, and also related command, the most I like will be the examples, because for new network engineer who without much experience, can actually more understanding with the example provide.

Let pick a normal command like “VLAN” (more…)

Actual Disk Space Calculation and Simple Math Disk Space Calculation!!! Which you prefer?

Most of us will be very curious, why our actually hard disk space does not match with the amount of disk space when we purchase?

For example our 2GB Pen drive, when we check on the disk space, the total space was 1.87GB only (Red Arrow), where another 0.13GB or 130MB missing?

See the image above, the red arrow show 1.87GB, but the green arrow show 2,014,621,696 bytes which already more then 2 billion bytes.

Actual DIsk Space Calculation vs Simple Math Disk Space Calculation

When we talk about actual disk space calculation, bytes… Kilo bytes… Mega bytes… Giga bytes… Tera bytes… The disk space is actually count by:

1KB = 1024bytes

1MB = 1024KB (1048576 bytes)

1GB = 1024MB (1073741824 bytes)

1TB = 1024GB

When talk about simple math disk space calculation, the calculation are (more…)
