How to use VNC viewer (remote desktop)

Using remote server is fun, you can use a VPS as you desktop. First of all you have to buy a vps and set up the server then use a app to operate it. It’s just like a TEAM VIEWER nothing else. If you can’t do it contact with your vps provider or any system admin. Lest see What Wiki Says

In computing, Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network.

Here is a small tutorial of connecting VNC viewer. There are many apps to connect. I prefer Real VNC its a cross-platform app. Download the appropiate version from Here and install it. If you are using windows then its nothing without a double click to run. If you are using Ubuntu then you have to change the file permission of the file you just downloaded. First open the terminal (CTRL+ ALT+ T) and enter the directory where the file was downloaded and enter below command.

$ cd your-directory
$ chmod -x filename
$ filename //or you can run the file by clicking on it

And you are done, you don’t need run those command again and again, just double click on the file and you will see like below

VNC Viewer_006

If are using windows then just click on the downloaded exe file and you will see almost same window. Anyway how you have to enter your login credentials to this window. Enter your IP address with port or you may have the domain with port. Press connect button and enter password in the recent appeared password window then you will see like below,


Graphics quality depends on you server config and your internet speed.

Where to start learning computer programming?

What is computer programming?

Do you know a event programmer, who organize an event like marriage/Christmas ? yes you must know. A programmer manage and organize an event by giving instruction to others. Computer programming is just like this.

Google says

“Creating a sequence of instructions to enable the computer to do something.”

You may know about computer hardware, a computer is a organization of Storage Device, MemoryProcessor, Output and input devices. What it will do when you start a very new computer without installing any OS or program? It will do nothing without showing a startup screen. Because it has no program. It has no instruction what to do now. Then we install an OS to make the computer alive. Here OS is an program which is giving all the instruction to computer and computer doing this. OK what OS you are using? Windows/MAC or any Linux destro? did you think that who made this? how they made this. Basically a computer program is a set of instruction and to making these instruction as well as program is computer programming. Computer don’t know any human language, it knows 0 and 1. Its quite impossible to make program by this machine (binary) Languages. Computer inventors (actually developers) made it easy by inventing programming language. Programming languages is nearer to human language with more readability. But its true that you have to convert (compile/interpret) the code to binary when you gonna input in a computer because computer knows binary. Here is a small infographic of compiling process (interpreter kind of same thing you will know details in the here)

I wont say Programming is easy task. It’s not easy actually. A Cashier count cash whole day, a guard stay on the gate everyday and you will find more example but they has no something which is creative actually they don’t need to be creative. Programming is not like this, programmers usually do new thing everyday. They are coding and inventing. So its not easy like others traditional profession. Actually you don’t need any extreme knowledge to learn programming. Many people say that programming needs a good math knowledge and if you are not a math expert then don’t go there. I don’t think so. Few months ago I meet with GittuBaba to get some suggestion, (FYI I am not a math expert, many times I failed in math in my life) I was interested to be a programmer but I was scared. GittuBaba asked me that “do you know basic math (+, -, *, /)?” I said “yes” then he said to start learning. Actually Its true that programming is too logical like math so who know math sometime it’s easier for him. I am learning and discovering new planets everyday.  If you can concentrate, confident and dedicated then start learning.

Here is an inspiring video must see.

Since Gmail applies labels to individual messages, you might see results that appear to have labels; in this case, another message in the same conversation thread has had a label applied to it.


Boolean operators

You can use boolean operators such as ‘OR’ when searching in Gmail.

For example, to look for messages from and messages that contain the subject line ‘Meeting reminder’, you can enter ‘ OR meeting reminder’ in your Gmail search box.

Using these along with Gmail’s advanced operators can be a great way of making your search criteria more powerful.

The ‘or’ function in Gmail is represented by ‘OR,’ and the ‘not’ function is represented by a minus (-). You also can use quotes (” “) to specify an exact phrase.
