Share mouse and keyboard with other PCs

September 24, 2012

If you have got back problems switching back and forth between keyboards and mice on your desk you need Synergy.

Synergy is an easy to set up open source application that allows you to share the keyboard and mouse of your main PC between multiple networked computers in your desk that are different platform like Mac, Windows and Linux.

The transition between the computers using the shared mouse and keyboard occur without any problems or complications, just move your mouse off the edge of one computer's screen on to another. Note that for this to work both machines have to be on the same network.


1 - Download the Synergy software on both machines. Click here to go to the Synergy webpage.

2 - Choose the download for your respective Operating System. For this tutorial, I demonstrate how to use Synergy to share a keyboard and a mouse between Windows 7 machines.

Once the installation for both is complete follow the instructions on screen:

Photo 1 (Choosing main computer as a server)

Set the main computer that has the keyboard and mouse you want to use as a server.
Note: There can only be one server in your setup. The other machines will act as client.

From the window below make sure "Server" is checked.

Then click the "Configure Server" button to see the next window and configure the client(s) position and name;

1 - You should be in "Screen and Links" tab, if not select that.
2 - From this window drag the little blue screen on the top right and drop in one of the square (In the position in which the second (client) PC is in relation to the main (server) physically.) If the client monitor is to the right of the server, drag the client monitor to the square to the right of the server monitor.
3 - Once the client icon is in place you must double-click and rename it with the real name it has on the network
Note: To check the network name of your pc, right click on "My Computer" and
then on properties, you will see the name and workgroup of your pc in this screen.

4 - When the client is configured, click the "OK" button and then click the "Start" button on the main window.

On the client pc:

1 - Select "Client"
2 - Enter the IP address of the computer acting as the Synergy server (PC where the mouse and keyboard are)
3 - Click "Apply" button
4 - Click "Start" button

Note: How to check the IP address of your PC in the Command Prompt:

1- Open the Command Prompt clicking in the Start button of your Windows 7 and
type cmd;
2 - Double-click in "cmd.exe".
3 - Type "ipconfig" without the quote marks and hit enter.
4 - If you are connected wirelessly you will find your IP like the photo below;
If you are on cable it will be under "Ethernet adapter Local Area Connection:"

Photo IP address

Now go back to the main PC and drag the mouse to the side where you put the client PC to share the mouse and keyboard between them. Done!

What is an Ultrabook?

What's the difference between a Hub, a Switch and a Router?

September 11, 2011
Hubs, switches, and routers are all devices that let you connect one or more computers to other computers, networked devices, or to other networks. Each has two or more connectors called ports into which you plug in the cables to make the connection. 

A hub is typically the least expensive, least intelligent, and least complicated of the three. Its job is very simple: anything that comes in one port is sent out to the others. That's it. Every computer connected to the hub "sees" everything t...

Explaining Binary, Bit, Byte, Kilobyte, Megabyte, Gigabyte and Terabyte

July 22, 2011

Binary is a number system used by digital devices like computers, cd players, etc.

In Binary you can write just zeroes and ones; In other words, Binary has only 2 different numerals (0 and 1) to denote a value, unlike Decimal which has 10 numerals (0,1,2,3,4,5,6,7,8 and 9).

Here is an example of a binary number: 10011100

If you separate the binary in columns like this, you will have your zeros and ones for our known normal numbers called decimal.

If we would continue wi...

Unix Tutorial (3) Files

July 5, 2011

cp (copy)

cp file1 file2 is the command which makes a copy of file1 in the current working directory and calls it file2


mv (move)

mv file1 file2 moves (or renames) file1 to file2

To move a file from one place to another, use the mv command. This has the effect of moving rather than copying the file, so you end up with only one file rather than two. It can also be used to rename a file, by moving the file to the same directory, but giving it a different name.

Unix Tutorial (2) - Directories

Unix commands come in all shapes and sizes, from simple and common to rare and hellish. The command itself is a rather brief set of letters (usually, but not always), possibly followed by options and / or arguments. To open an UNIX Terminal window, click on the "Terminal" icon from Applications/Accessories menus.

When you first login, your current working directory is your home directory. Your home directory has the same name as your user-name, for example, reny, and it is where your personal...

What is Unix?

Unix is not that easy to define. At the lowest level it is simply the kernel (suite of programs which make the computer work) of an operating system. It was first developed in the 1960s, and has been under development ever since. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops.
UNIX systems also have a graphical user interface (GUI) similar to Microsoft Windows which provides an easy to use environment. However, knowledge of UNI...
