What is a VPS?
(fr) Un serveur dédié virtuel (également appelé serveur virtuel), en anglais virtual private server (VPS) ou virtual dedicated server (VDS) est une méthode de partitionnement d'un serveuren plusieurs serveurs virtuels indépendants qui ont chacun les caractéristiques d'un serveur dédié, en utilisant des techniques de virtualisation. Chaque serveur peut fonctionner avec unsystème d'exploitation différent et redémarrer indépendamment. Dans le domaine de l'hébergement web, plusieurs dénominations recoupent le même type d'offres et donc de services. Les acronymes VPS (Virtual Private Server) et VDS (Virtual Dedicated Server) désignent le même concept, et leur usage est parfois confus.

(en)Virtual private server (VPS) is a term used by Internet hosting services to refer to a virtual machine. The term is used for emphasizing that the virtual machine, although running in software on the same physical computer as other customers' virtual machines, is functionally equivalent to a separate physical computer, is dedicated to the individual customer's needs, has the privacy of a separate physical computer, and can be configured to run as a server computer (i.e. to run server software). The term virtual dedicated server or VDS is used less often for the same concept, however it may indicate that the server does not use burst/shared ram through multiple machines, as well as individual CPU cores.

In addition to reducing hardware and power expenses, virtualisation allows businesses to run their legacy applications on older versions of an operating system on the same server as newer applications.

Each virtual server can run its own full-fledged operating system and can be independently rebooted.

Partitioning a single server so that it appears as multiple servers has long been common practice on mainframe computers and mid-range computers such as the IBM AS/400. It has become more prevalent with the development of virtualization software and technologies formicrocomputers.

Move to the Cloud

The cloud computing buzz has continued, and 2012 may well be the year when moving application development to the cloud becomes an enticing alternative. Traditional means to manage the complexity of today’s system landscapes increasingly are simply too expensive and time consuming.
Look for cloud application platforms that allow you the option of cloud or on- premise deployment, so as to preserve your options into the future.

Moving to the cloud helps organizations to:

  • Reduce total IT spend
  • Minimize IT infrastructure expenditure
  • Increase IT responsiveness

Learn how to take your teams to the next level. Visit www.collab.net/5things to access additional materials that will help your teams accelerate software delivery.

Occupy Geeks Are Building a Facebook for the 99%

Wired News (12/27/11) Sean Captain

As part of the Occupy Wall Street (OWS) movement, a team of Web and mobile application developers is redesigning social networking for the era of global protests. The team hopes their technology can go beyond OWS to help establish more distributed social networks, improve online business collaborations, and add to the Semantic Web's development. The Occupy movement already has local networks set up for each occupation site, and the activist-developers are building an overarching, international network called Global Square. A major challenge to all new social networking efforts is ensuring that members are trustworthy. To build trust, local and international networks will use a friend-of-a-friend model. "You have to know someone in real life who sponsors you," says Occupy Movement developer Ed Knutson. Global Square will connect through standards designed to link up disparate technologies. The OWS projects also rely on Open ID and OAuth, which let users sign into new Web sites using their logins and passwords from social networks such as Facebook, Google, and Twitter. In the new OWS technology, an activist's local-occupation network can vouch for a user to another network, and since the local networks all trust each other, they all trust that activist.

The U.S. Is Busy Building Supercomputers, but Needs Someone to Run Them

From ACM TechNews:
The U.S. Is Busy Building Supercomputers, but Needs Someone to Run Them
Daily Beast
(12/28/11) Dan Lyons

The United States is rapidly adding to its collection of supercomputers, with new high-performance computing (HPC) systems under development at various labs. However, there are not enough people who know how to make use of all the new supercomputing power, say HPC industry experts. This talent shortage is the "missing middle," meaning there are enough specialists to run the handful of world-beating supercomputers that cost a few hundred million dollars, and plenty of people who can manage ordinary personal computers and servers, but there are not nearly enough people who know how to use the small and midsized HPC machines that cost between $1 million to $10 million. "We need people who can build the applications and algorithms needed to effectively use the equipment," says the University of Tennessee's Jack Dongarra. The Virtual School for Computational Science and Engineering is a program that offers online courses for graduate students who want to learn how to use HPCs. This year, 1,000 students participated, up from 40 in 2008 when the program began, according to National Center for Supercomputing Applications director Thom Dunning.

Try Funambol an Open Source personal Cloud

Learn About Funambol

Many people want quick and easy access to their email, contacts, calendars, tasks and notes, regardless of where that information is stored.

Funambol syncs this data with billions of phones and with thousands of applications and online services. It doesn't matter if you use Gmail, Yahoo!, AOL, Hotmail, Outlook or Thunderbird, with Funambol, you can sync your email & PIM on many mobile handsets.
Funambol is the leading provider of mobile cloud sync. Its mobile open source platform can be used for many types of mobile applications, including push email, PIM data synchronization and device management. It provides C++ and Java client APIs and server side Java APIs. It facilitates the development, deployment and management of a wide range of mobile projects.
Funambol consists of several components, including:
  • Funambol Data Synchronization Server: a mobile server providing synchronization services for mobile devices and PC software, as well as push email capabilities.
  • Funambol Connectors: interfaces to various email systems, databases, file systems and applications, for bidirectional data synchronization.
  • Funambol Clients: client software applications that enable users to synchronize email and PIM data (contacts, calendar, tasks and notes) between a wide range of mobile devices and the Funambol server.
  • Funambol Software Development Kit (SDK): a suite of tools to develop sometimes-connected mobile applications on devices in Java (J2SE and J2ME) and C++, and to add data sources to the server.
  • Funambol Administration Tool: a simple graphic tool to administer Funambol installations.
  • Funambol Device Management: an OMA DM server to remotely manage mobile devices.
The Funambol project was started in 2001 by developers because of the lack of an open source Java implementation of the SyncML (OMA DS) standard. This original project was known as Sync4j. At the beginning of 2006, it changed its name to Funambol, to have the same name as the company that grew out of the original project and that now funds its development.
The Funambol project has gone beyond the original server engine. It now includes administration tools and many mobile device clients. Funambol is in production use all over the world and supports millions of end users. The project has been granted several awards from prestigious industry organizations for innovation in the mobile industry.
