BigBlueButton - From BigBlueButton is a web conferencing server that takes advantage of several other open source servers.

BigBlueButton -

It is a complex package that I prefer to run on its own Ubuntu server (either on a standalone machine, in a separate partition, or within a virtual machine). This is necessary partly because BigBlueButton runs either on a 32-bit Ubuntu Jaunty 9.04 OS or on a 32-bit or 64-bit Lucid 10.04 OS currently, and I use a more recent edition of the (K)Ubuntu OS for everything else. Also, the default configuration of BigBlueButton uses ports for its components that might occasionally conflict with other servers. Rather than reconfigure all the other servers (to avoid the possibility of port conflicts with BigBlueButton), it is easier to install (and easier to maintain) BigBlueButton if it is in a self-contained environment. If BigBlueButton is to be used only for a webinar once-in-a-while, it might be easiest to set it up in its own partition.

How to build a web widget (using jQuery) - Alex Marandon

Although all the necessary information can be found on the web, I couldn’t find a really comprehensive guide about doing this with jQuery so I decided to write this one. I’ll cover only techniques which are specific to web widgets so you should already be familiar with JavaScript, jQuery and web development if you want to follow easily. The interesting points will be: ensure the widget’s code doesn’t accidentally mess up with the rest of the page, dynamically load external CSS and JavaScript files, bypass browsers’ single-origin policy using JSONP.

Don’t worry if all this doesn’t make sense to you yet, we’ll see in details what these techniques are used for in the context of building web widgets. That’s really all that a web site owner would need to include our widget on her pages. Can’t it be even simpler? Index of /pub/misc/mysql/Downloads/MySQLGUITools. The Anatomy of Search Technology: blekko’s NoSQL database. This is a guest post (part 2, part 3) by Greg Lindahl, CTO of blekko, the spam free search engine that had over 3.5 million unique visitors in March.

The Anatomy of Search Technology: blekko’s NoSQL database

Greg Lindahl was Founder and Distinguished Engineer at PathScale, at which he was the architect of the InfiniPath low-latency InfiniBand HCA, used to build tightly-coupled supercomputing clusters. Imagine that you're crazy enough to think about building a search engine. It's a huge task: the minimum index size needed to answer most queries is a few billion webpages. Crawling and indexing a few billion webpages requires a cluster with several petabytes of usable disk -- that's several thousand 1 terabyte disks -- and produces an index that's about 100 terabytes in size. Serving query results quickly involves having most of the index in RAM or on solid state (flash) disk. You might think that Amazon's AWS cloud would be a great way to reduce the cost of starting a search engine.

Social Network Analysis

Network Data Collection and Representation Network Theories Analysis of Network Data Software Applications Books and Journals Article References Selected Online SNA Portals Ulrike Gretzel November, 2001 What is Social Network Analysis? Social network analysis is based on an assumption of the importance of relationships among interacting units. Actors and their actions are viewed as interdependent rather than independent, autonomous units Relational ties (linkages) between actors are channels for transfer or "flow" of resources (either material or nonmaterial) Network models focusing on individuals view the network structural environment as providing opportunities for or constraints on individual action Network models conceptualize structure (social, economic, political, and so forth) as lasting patterns of relations among actors Wasserman, S. and K.
