Cloud Computing: 7 Online Virtual Desktop

by

A web desktop or webtop is a desktop environment embedded in a web browser or similar client application. A webtop integrates web applications, web services, client–server applications, application servers, and applications on the local client into a desktop environment using the desktop metaphor. Web desktops provide an environment similar to that of Windows, Mac, or a graphical user interface on Unix and Linux systems. It is a virtual desktop running in a web browser. In a webtop the applications, data, files, configuration, settings, and access privileges reside remotely over the network. Much of the computing takes place remotely. The browser is primarily used for display and input purposes.

The terms “web desktop” and “webtop” are distinct from web operating system, a network operating system such as TinyOS or distributed operating system such as Inferno. In popular use, web desktops are sometimes referred to incorrectly as web operating systems or simply WebOS.

In the past few days, I’ve tested a bunch of virtual online operating systems and web desktop applications, I’ve gathered the best of them that I’ve personally tested and found interesting to be shared with you, enough talk and let’s get them listed:

4 free open source NMS

by

A Network Management System (NMS) is a combination of hardware and software used to monitor and administer a network. NMS systems make use of various protocols for the purpose they serve. For example, SNMP protocol allows them to simply gather the information from the various devices down the network hierarchy. NMS software is responsible for identification of the problem, the exact source of the problem and solving them. The NMS systems not only are responsible for the detection of faults but also for collecting the statistics of the devices over a period of time. They may include a library where the previous network statistical data over a period of time is stored along with the problems and the solutions that worked in the past. This library can come useful in case a fault is found. NMS software can consult the library and search for the best possible method to resolve the problem.

In this post I gathered top 4 Free Open Source Network Management Software that you can use as an IT Administrator in your network, Whether you run small or enterprise network, you will find those tools handy and effective in doing your monitoring work as simple as it could be.

Synergy+ Share a single mouse and keyboard between multiple computers

by

During my search for a software to make me share a single mouse and keyboard across my 4 work stations instead of buying a KVM, I came across with this wonderful open source software which is called “Synergy+ (synergy-plus)”. Synergy+ lets you easily share a single mouse and keyboard between multiple computers with different operating systems, without special hardware. All you need is a LAN connection. It’s intended for users with multiple computers, where each system uses its own display. It’s a little like having a 2nd or a 3rd desktop.
Synergy+ is free open source software. It’s not a KVM or VNC tool, but it does achieve similar results (but with added convenience). No need to press any buttons when you want to change desktops, and your keyboard input goes to the same screen that your mouse cursor is on.
Synergy Plus

Interesting features:

  • Move your mouse easily between computers.
  • Requires nothing other than existing Ethernet.
  • Copy and paste between your computers
  • No need to press any buttons (unlike KVM)
  • You can still use multiple monitors on the same computer
  • Lock the mouse to one screen temporarily (useful for games)

Synergy plus is currently available for Windows, Linux, & Mac operating systems at: Synergy+ Project Page hosting on Google Code.

3 free Operating systems for your netbook

by

Netbooks (sometimes also called mini notebooks or ultraportables) are a branch of subnotebooks, a rapidly evolving category of small, lightweight, and inexpensive laptop computers suited for general computing and accessing Web-based applications; they are often marketed as “companion devices”, i.e., to augment a user’s other computer access.

At their inception in late 2007 — as smaller notebooks optimized for low weight and low cost — netbooks omitted certain features (e.g., the optical drive), featured smaller screens and keyboards, and offered reduced specification and computing power. Over the course of their evolution, netbooks have ranged in size from below 5″ screen diagonal to over 10.1″. A typical weight is 1 kg (2-3 pounds). Often significantly less expensive than other laptops, by mid-2009, some wireless data carriers began to offer netbooks to users “free of charge”, with an extended service contract purchase.

In the short period since their appearance, netbooks have grown in size and features, now converging with new smaller, lighter notebooks. By August 2009, when comparing a Dell netbook to a Dell notebook, CNET called netbooks “nothing more than smaller, cheaper notebooks,” noting, “the specs are so similar that the average shopper would likely be confused as to why one is better than the other,” and “the only conclusion is that there really is no distinction between the devices.” However, in the same month, Walt Mossberg called them a “relatively new category of small, light, minimalist, and cheap laptops.”

I’ve tested few operating systems on my netbook to achieve the max performance for my work, I figured out that there are only 3 free operating systems that can really turn your netbook into something amazing. Those 3 operating systems are:

1- Jolicloud

jolicloud
Jolicloud is not a traditional OS. It was built for netbook users to leverage the Cloud and make their life easier.

2- Ubuntu

3- LinuxMint

linux-mint
Linux Mint is a Linux distribution with a very strong emphasis on accessibility and out-of-the-box ease of use for new users.

5 Virtualization Application for development testing

by

As a developer, and tester at the same time, I need to have multiple operating systems to test my applications or even my design to get a better look of what the user will see. Of course I can not have multiple OS that dual boot on my system cause that would be painful especially when rebooting the main system to log into another one. Therefore I use a virtualization applications to operate multiple operating systems into one screen.

Here at my work we have a license to use VMware Workstation to test our applications, but when um at home, I can not afford the money to buy one, so I searched for open source and freeware that do virtualize different operating systems medium and here is a list of top 5 application you may want to use:

VMware Player
