About TAB and Shift+TAB Buttons

Bismillah. Usually we use TAB for jumping from one button to another button focus in any programs we use. We jump from one button to another button or from one text box to next textbox in Gmail Registration Form. But how if we want to jump back? Shift+TAB will take you back one element.

Yes we can operate computer with less mouse usage! It is easier for people who want to be pro when they must use keyboard widely in one hand and use mouse with other hand. So use them!

[TUTORIAL] How If You Don't Know How To Use A Command?

Bismillah. This is a simple tutorial for all of my dear brothers. What we do if we don't know what should we do in Linux terminal? We can type "man" without quotes followed by command name. Or you can just type "help" without quotes. I will show you.

A simple example, you can type man traceroute to show traceroute program's manual. Okay, traceroute is a command name and it is a program for printing the route packets trace to network host.

You can exit the manual page by typing "q" without quotes. It is easy to know details of program in terminal!

And you can reveal the help page of every program installed by typing "--help" without quotes after command name. This is a simple example too, just type traceroute --help and a help page will revealed for you. Ow, help is different from man. You can see that help is a small summary from man.

Okay, you will not find man page or help page if the program you want to know is not installed in your Linux yet. So, you can do this tutorial by typing another program name than my traceroute here, such as ls, fdisk, rm, and many more. You can see many command hy typing "help" only without quotes.

And hey, I am forget. You should always press enter after typing any command. Enter means execute. Yes, now you can do it. Who will we ask if we don't know the command? Man and help! I hope it is will be useful for you all, my dear brothers!

C Programming for Me

It's easy but also hard in some cases. Easy because the syntaxes is very short compared with another laguage like Java and hard because many times I feel so boring with programming. Hm, maybe I don't have the sense yet. No other language can defeat C in case of portability and scalability. C can run in most of hardware in this world begin on embedded system until supercomputer. C has so many compiler both for Linux or Windows. It is important for me because I use Linux (so I use gcc as my compiler). Yes C language has UNIX root because it was born on UNIX then Linux was born from UNIX so programming C in Linux is a good way. But I dont deny any C programming on Windows. And C has most tutorials in the internet then another language. And the hardest part of learning C for me now is trying some codes and modify them. I hope I can do that from now.

How To Configure Proxy Server for Ubuntu Software Center

Ubuntu Software Center doesn't have configuration options for proxy server like Synaptic Package Manager. In Synaptic, you can set server URL, port number, username, and password. Such configuration makes Synaptic can enter directly to proxy server with authentication so Synaptic can be connected via that proxy server. But it is different with Ubuntu Software Center (USC). USC hasn't graphical configuration like Synaptic so we must set proxy server configuration in Ubuntu Global Network Proxy then click Apply System Wide. But that way will never success because Global Proxy Settings doesn't have place to set username and password. Now, how to enter proxy server configuration completely with right authentication so USC can connect to internet behind a proxy server? This is the steps.

1. Open Terminal (Ctrl+Alt+T)

2. Change directory to /etc/apt/apt.conf.d/ with command: cd /etc/apt/apt.conf.d/

3. Make a file there named 01proxy with command: sudo gedit 01proxy.

4. Check the existence of 01proxy with command: ls. If there, then a name 01proxy will appear in display. If not, repeat step 3.

5. Edit content of 01proxy with command: sudo gedit 01proxy.

6. Fill it with a row of this words:

Acquire::http::proxy "http://username:password@proxyserver:port/";

with note: username is your proxy username, password is your password, proxyserver is yuor proxy URL or it's ip number, port is port number to access the proxy (if you don't know, please confirm to your proxy administrator). Example:

Acquire::http::proxy "http://malsasa:traumalin89@proxyserver.server.net:443/";

7. Save (Ctrl+S).

Now you can try to install a program. You can start with installing Stardict, a simple but great dictionary.
