Are you looking for an easy way to collaborate with research colleagues online without getting bogged down with software bells and whistles? A wiki might be the solution for you. Here we review five wiki platforms that range from free, open source solutions to more expensive, hosted solutions. The trade off comes mainly from the development time involved in setting up and managing your wiki.

Wikispaces: Wikispaces is an easy to use collaboration system that can be used privately for a fee or open to the public for free (as long as you don't mind seeing Google text ads on the side). All it takes is a simple username, password, email address and wikiname to get started with a free account. Universities can enjoy unlimited users for a flat rate. Columbia University created Wikischolars on the Wikispaces platform for its university faculty and research scientists.

PBworks: PBworks (formerly known as PBwiki) offers a free wiki with the option of creating a private collaboration space, which isn't available in the Wikispaces free edition. New wikis come with sample pages that you can use as best practice samples for setting up pages such as a document repository, a meeting minutes page, a project tracker, and more. Cal Newport at Study Hacks has a helpful and detailed post on How to Build a Paper Research Wiki using PBworks.

Teach Yourself How to Code: How many times have you picked up a programming book only to get bored and drop it by about the third chapter? Lifehacker's Gina Trapani has a great post on how to find your programming niche and teach yourself to learn languages and build applications or websites. Add speed to your efforts with these tips from Nettuts.

Universities with the Best Free Online Courses: If you don't have the time, money, or SAT scores to go to a top university, don't let that stop you from getting an education. Education-Portal posted a list of their top ten universities with online courses, including MIT, Stanford, Berkeley, and Carnegie Mellon. You can find more free online university courses in our directory.

How to Schedule Your Writing Like a Professional Writer: Study Hacks has a lot of great tips that are particularly suitable to academics and researchers. If you only take one tip away from the whole article, try this one on: write early in the morning when your brain is fresh and before distractions set in.

Ben Shneiderman, Professor of Computer Science at the University of Maryland, gave a talk for the Stanford University Human Computer Interaction Seminar on his ideas around the concept of Science 2.0, which is generally comprised of collaborative internet applications such as blogs, wikis, and online social networks. In the video, Prof. Shneiderman discusses how the collaborative web can be harnessed to support citizens in times of crisis and natural disasters.

Over the decades scientists in quantitative research fields have often experienced a tug-of-war between the desire for large (and expensive) shared computing environments and smaller but powerful workstations that a single scientist could procure for their own lab. The trade-off typically is between the cost of managing one's own system versus the control that one gives up with a large shared resource. Sometimes you need a lot of computing power to answer a research question, but you don't need it every day nor for very long. This is where cloud computing steps in. Amazon's Elastic Compute Cloud (Amazon EC2), for example, is a commercial web service commonly used by technology startups who want to be able to scale quickly without committing to large upfront costs. Last month, Argonne National Laboratory announced that they have been awarded $32 million in ARRA (American Recovery and Reinvestment Act) funds from the Department of Energy (DOE) to study cloud computing "as a cost-effective and energy-efficient computing paradigm for scientists to accelerate discoveries in a variety of disciplines." The idea is to eventually make cloud computing resources available to scientists to study problems in climate, biology, chemistry, and more.
