Acronyms of the week — IaaS and SaaS

Image courtesy of Steve Tainton.

As technology marches on, so does our vocabulary. New words, phrases and acronyms are probably being coined as we speak.
At the recent Summit 09 in Banff, Alberta, jargon was flying thick and heavy. In response, we've added two particularly hot acronyms to our glossary.

Infrastructure as a Service (IaaS) - This phrase, first coming into use in late 2006, describes the delivery of infrastructure, including data and processing power, as an outsourced service.Read more about IaaS.
Software as a Service (SaaS) - A model whereby software is provided as a service. There are two primary methods of SaaS:
The software is hosted on the provider's web server, and accessed through a web portal, such as a science gateway.
The user can download the application, but it is remotely disabled when the license expires.

Link of the week - Bid for your grid

Ever since grid computing was conceived, there have been visions of one colossal standard grid which is open and simple for anyone to use, just as you can plug into an electrical power grid to get as much electricity as you need on demand.
The dream of making grid computing a universal on-demand utility has yet to be realized. But what if instead of being like a power grid, grid computing resources were available through an open market?
The GridEcon project has developed a platform which turns grid computing resources into commodities which can be bought and sold like stock.
Because the ideology behind grids when they were first established was to enable computing resources to be shared for free, a market system for sharing computer resources seems to go against this ethic. However, the rising popularity of clouds — once described as &ld

It’s hard not to have a soft spot for some of the gorgeous visualizations science computing produces. But in our quest for form, have we lost sight of function?
That’s the question that drove Manuel Lima, a London-based interaction designer, to write the Information Visualization Manifesto, which you can read at his blog. Lima’s manifesto states 10 directives for any project in the information visualization realm:

Form follows function
Start with a question
Interactivity is key
Cite your source
The power of narrative
Do not glorify aesthetics
Look for relevancy
Embrace time
Aspire for knowledge
Avoid gratuitous visualization

His manifesto prompted 21 comments, and his follow-up post received more. A thoughtful response by computer science professor Robert Kosara added fat to the

On 24 June, iSGTW reported on “citizen cyberspace,” volunteers participating in on-line science projects.
What’s happened since then?
The United Nations Institute for Training and Research (UNITAR), the University of Geneva (UNIGE), and the European Organization for Nuclear Research, (CERN) have formally agreed to collaborate on a Citizen Cyberscience Center Project, to be hosted at UNITAR offices at CERN.
The goal is to provide scientists with an inexpensive form of distributed computing power that is complementary to grid technology – as seen in such processing-intensive problems as the LHC@home project or the “Africa@home” project.

Link of the week – Flashback to 1967: computers are just hype

A screen grab of the story's opening spread.  Image courtesy of Modern Mechanix blog.

1967. Charlie Chaplin is out and Jimi Hendrix is in. It may be the summer of love, but it is also a year of riots and violence. While war rages in Vietnam, the space race is picking up speed.
In that atmosphere, it’s hardly surprising to see well-written, well-researched literary journalism appearing in Playboy. Max Gunther’s “Computers: Their built-in limitations” mixes piquant wit with an easy writing style that draws the reader in, creating an extremely well-crafted piece.
Too bad his criticisms of computing were so off the mark that today, his commentary has become unintentional satire.
There are many parts that may bring a smile to your lips. Here are a few gems:

Computers are just a status symbol. “To have a computer is ‘in.’ Even if you’re a scruffy little company that no

The man who founded Sun Microsystems and wrote the first check for a start-up called Google now wants to build 100-gigabit switches for the huge data centers of the looming cloud.
Andreas von Bechtolsheim explained his reasoning, saying: “Historically, people literally had to buy a computer to then use the program or the application they wanted for the business, payroll, database and so on. In the future, all of these applications will run just on the web in some big remote data centers located in the places of the world where the power is cheapest and the user only needs a browser on the laptop or on the mobile phone to access these applications.”

This week’s Link is the Gaia project — a global space astrometry mission. Its goal is to make the largest, most precise three-dimensional map of our galaxy by surveying an unprecedented number of stars, more than a billion. The data- handling is done with a combination of grid and cloud computing.
Gaia will monitor each of its target stars about 70 times over a five-year period, precisely charting their positions, distances, movements and changes in brightness. It is expected to discover hundreds of thousands of new celestial objects, such as extra-solar planets and failed stars called brown dwarfs. Within our own solar system, Gaia should also identify tens of thousands of asteroids.Additional scientific benefits include detection and characterization of tens of thousands of extra-solar planetary systems, a comprehensive survey of objects ranging from huge numbers of minor bodies in our solar system, through galaxies i

Imagine what your field could accomplish if everyone pooled their data into one massive computer grid.
That’s exactly what astronomers have accomplished, in the form of the International Virtual Observatory Alliance. The alliance works to develop standards that ensure interoperability, so that everyone can share data freely. Since the IVOA was founded in June 2002, a number of discoveries have been made using virtual observatory tools.
For instance, in April 2003, U.S. scientists discovered a previously unknown brown dwarf star during a trial run of their National Virtual Observatory. And in June 2004 European scientists discovered thirty powerful supermassive black holes using a virtual observatory to analyze data gathered by both the European Southern Observatory and N

Last week, Berlin hosted the 7th HealthGrid conference, from 29 June – 1 July. The feeling pervading the event was that the HealthGrid community had progressed a long way — and yet for grids to reach their full promise in the area of health care, a lot of work remains.“I first participated in the conference three years ago in 2006,” said Xin Zhou, a conference presenter and maintainer of the grid infrastructure inside the University of Geneva Hospital. He added, “Back then, we were talking about ‘the plan.’ Many people then presented what they were going to do; now they are presenting the applications. This represents real progress in the research domain and shows movement towards practice.”Simple intuitive interfaces, appealing to non-specialist users, were an oft-called for commodity. In a demonstration of just such an interface, Tobi

At the University of Nottingham, UK, researchers have created an up-to-the-minute Periodic Table that contains videos about each element and its creation. They even have the latest addition, with the tentative symbol “Uub.” Image courtesy University of Nottingham 

There may soon be an addition to the periodic table: the “super-heavy” element 112, created by a team of German scientists at the Society for Heavy Ion Research in Darmstadt, who used a linear particle accelerator to fire a beam of zinc ions at a target of lead atoms.
Nuclei of the two elements merged to form the nucleus of the highly unstable new element.
Its discovery had to be independently verified; so far only four atoms have ever been observed — but it has now been recognized by the International Union of Pure and Applied Chemistry (IUPAC).
The researchers have yet to come up with a name for their find, which is necessary for it to be  f

Link of the week - IBM and WCG quickly launch influenza treatment project

The 1918 Spanish flu epidemic was caused by an influenza A (H1N1) virus (shown above), killing more than 500,000 people in the United States, and up to 50 million worldwide. The possible source was a newly emerged virus from a swine or an avian host of a mutated H1N1 virus. Many people died within the first few days after infection, and others died of complications later. Nearly half of those who died were young, healthy adults. Influenza A (H1N1) viruses still circulate today after being introduced again into the human population in the 1970s.
