Handle Multiple Machines with Single Keyboard & Mouse

Synergy  lets you easily share your mouse and keyboard between multiple computers on your desk, and it's Free and Open Source. Just move your mouse off the edge of one computer's screen on to another. You can even share all of your clipboards. All you need is a network connection. Synergy is cross-platform (works on Windows, Mac OS X and Linux).

How Synergy works.

There are three monitors on my desk, two of which are attached to one computer and one monitor that is attached to another computer. I have two keyboards and two mice on my desk, and switching back and forth between those keyboards caused me to have all sorts of back problems. Sure, I could use a KVM, but I didn’t have one handy, so how could I lose one keyboard/mouse combo? I didn’t think it was going to be possible, until I found an incredibly simple and free solution called Synergy.
Synergy is an easy to set up open source application that allows you to share a keyboard and mouse between multiple networked computers. The software allows you to share a single keyboard and mouse between Windows, Mac, and Linux computers.

What you need to use Synergy

  • At least two computers with separate monitors
  • A network connection (both machines on the same network)
  • The Synergy software

Installing and using Synergy

For this tutorial, I demonstrate how to use Synergy to share a keyboard and mouse between a Windows 7 machine and a Ubuntu Linux machine.
Install the Synergy software on both the Windows and the Linux machines. The Windows installation is simple: download the Windows .exe file, double-click it, and walk through the wizard. Follow these steps for the Linux installation:
  1. Download the installation file for Ubuntu.
  2. Open a terminal window.
  3. Change into the directory the file was downloaded into.
  4. Issue the command sudo dpkg -i synergy-XXX-Linux-xxx.deb (XXX is the release number and xxx is your system’s architecture).
  5. Type your sudo password.
  6. Hit the Enter key.
When the installation for both is complete, you should start the software. When you do this, the main Synergy window will open. You have to set one instance up as the server and one as the client; we’ll set up the Windows machine as the server and the Linux machine as the client.
Let’s open the Windows Synergy application by going to Start | All Programs | Synergy. When the app opens, it will automatically go to the system tray. Right-click the Synergy icon (the blue and green circle) and select Show. From the new window (Figure A) make sure Server is checked.
Figure A
The log window is a real-time update of what is happening during the connection phase. 
Then click the Configure Server button in Figure A. From the Screens And Links tab in the new Server Configuration window that opens (Figure B), click the monitor icon in the upper right corner and drag it next to the center square. 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.
Figure B
You can also configure hotkeys and polling from the other tabs. 
Once the client icon is in place, double-click the icon and rename it. You must rename the client with the hostname of the actual client computer. When the client is configured, click the OK button and then click the Start button on the main window.
Now, over to the client machine. On Ubuntu, open the Dash and type synergy. Click the application launcher. The Synergy icon will appear in the notification area. Right-click the icon and select Show. From the main window (Figure C), do the following:
  1. Select Client.
  2. Enter the IP address of the computer acting as the Synergy server.
  3. Click the Apply button.
  4. Click the Start button.
Figure C
If you’re unsure of the client’s host name, it’s right here. 
You should be able to grab the mouse and keyboard attached to the server machine and move it across to the client machine. After you give this amazing little app a try, report back and let us know if it makes your life easier.

Green computing

Green computing, the study and practice of efficient and eco-friendly computing resources, is now under the attention of not only environmental organizations, but also businesses from other industries. In recent years, companies in the computer industry have come to realize that going green is in their best interest, both in terms of public relations and reduced costs. This article will take a look at several green initiatives currently under way in the computer industry, as well as issues that have been raised regarding these initiatives.

The field of "green technology " encompasses a broad range of subjects — from new energy-generation techniques to the study of advanced materials to be used in our daily life. Green technology focuses on reducing the environmental impact of industrial processes and innovative technologies caused by the Earth’s growing population. It has taken upon itself the goal to provide society’s needs in ways that do not damage or deplete natural resources. Mainly this means creating fully recyclable products, reducing pollution, proposing alternative technologies in various fields, and creating a center of economic activity around technologies that benefit the environment.

Perhaps the most talked about aspect of green technology is the promise of alternative energy sources. Sun, wind, water, sugar — we’ve heard about them all. However, scientists are working on other aspects of the problem as well, testing building materials and studying chemical processes to reduce the use and generation of hazardous substances. Nanotechnology is also being used in an attempt to manipulate materials at the nanometer scale; scientists are hoping it can transform manufacturing on a global level, from government purchasing to a technological revolution.

The huge amount of computing manufactured worldwide has a direct impact on environment issues, and scientists are conducting numerous studies in order to reduce the negative impact of computing technology on our natural resources. Companies are addressing e-waste by offering take-back recycling programs and other solutions, with lower energy consumption and less wasted hardware. A central point of research is testing and applying alternative nonhazardous materials in the products’ manufacturing process.

Let us Understand it better

We can't live without PCs, so let’s learn how to live with them in a way that makes them friendlier to the environment. Currently, PC’s consume far too much electricity and generate too much e-waste to to be considered an Eco-friendly solution by today’s standards. With a typical PC taking approximately 110 watts to run, and with well over 1 billion of them on the planet, it’s easy to understand what the Silicon Valley Toxics Commission is saying about e-waste is being the fastest growing part of the waste stream.


Green Computing is the Future

The benefits of green computing are clear. As the number of PCs approaches 2 Billion by 2015, the potential savings related to energy use , CO2 emissions and e-waste are undeniable.

The Global Impact of Billions of PCs

How many computers are actually in use? According to a report by Forrester Research, by the end of 2008, there were over one billion PCs in use worldwide.

As PC adoption grows globally, it is estimated that there will be more than two billion PCs in use by 2015. It took 27 years to reach one billion but will only take 7 more years to double that number. With this trend, something needs to change.

If NComputing systems were used at a ratio of 6 NComputing devices to each PC:

Energy use would decline by over 143 billion kilowatt hours per year
CO2 emissions would decrease by 114 million metric tons. That’s like planting 550 million trees!
E-waste would be reduced by 7.9 million metric tons

Current Available Solutions

Simple and Efficient Solution by Using Desktop Virtualization 

Today's PCs are so powerful that we no longer need one PC per person. We can tap into the excess power in one PC and share it with many users. NComputing thin client devices use just 1 to 5 watts, last for a decade, and generate just a few ounces of e-waste. Not only is this a simple solution to a complex problem, the efficiencies achieved using this technology are amazing. NComputing solutions save 75% on hardware, and since they draw less than 5 watts of power, you can reduce your energy footprint by as much as 90% per user. NComputing thin client devices produce practically no heat, reducing the need for energy-consuming air conditioning. Electricity savings alone can pay for the NComputing virtual desktops in as little as one year

Power generation

One major green computing change that will benefit the environment, is to use alternative power sources.Most energy providers now have an option for using "green power" generated from Solar, windmills, hydroelectric, photovoltaic panels, or nuclear sources, although some of these sources are perceived to be more environmentally friendly than others. 

Solar UPS system, one among the most convenient and growing technology specially designed for urban houses and commercial institutions, which require and un-interrupted power source with a considerable saving in electricity bill. The main power source of the system is Solar PV Modules, which produces DC electricity from sunlight. This DC electricity is stored into the batteries. The sine wave inverter of the Power Conditioning Unit converts DC into AC to supply the AC loads. Works from solar (INVERTER mode) when battery is fully charged and continue to work in this mode till battery state of charge reaches 50% Changes over to Mains supply, when battery state of charge become 50%. At this moment, if utility power is not available, system continue to work in Inverter mode till battery state of charge reaches 20%.

In MAINS  mode, if utility power fails, it automatically change over to INVERTER mode When battery state of charge become 20%, energize a contact, which can start a diesel generator or external power source like wind mills etc.

Key Features: 

Maximum utilization of Solar Energy
Energy Management Function
Microprocessor controlled
Maximum Power Point Tracking (MPPT)
Built-in Automatic Voltage regulation (AVR)
Pure Sine Wave Inverter
Built-in over voltage and short circuit protection
