Elgg 1.5 has been released by Curverider. Over the past few days, Elgg’s revisions to their Subversion repository had slowed as they put the finishing touches on the new release.
Elgg 1.5 is available as a package or from the subversion repository. This development means that I will return to my comparisons of Elgg and BuddyPress. It also signals developers, including myself, to update Elgg themes and plugins.

Curverider released a second release candidate for Elgg 1.5 today. It can be downloaded as a tarball from their site, or you can get it from the subversion library. Release Candidate 2 brings about 40 new revisions to Elgg code since the release of the first Release Candidate last week.

A release candidate for Elgg 1.5 was unvealed by the Curverider team today. Release candidates have been tested and are generally very stable. Nonetheless, Curverider does not recommend its use for production sites.
The core Elgg team has been working feverishly to squash remaining bugs and enhance Elgg’s performance. They have committed over 100 commits to their Subversion repository since Saturday.
I have personally tested earler incarnations of Elgg 1.5 and am glad to report that it works well. I am sure that anybody has worked with earlier versions of Elgg will be pleased with the latest. Stay tuned for another post highlighting more enhancements to the software.

Social Bookmarking site Ma.gnolia experienced a disastrous database corruption which has brought the site down. On February 17, Ma.gnolia owner Larry Halff announced that the data could not be recovered. He answered some interesting questions about Ma.gnolia and cloud computing services in general in this interview. It is long, but I really think the video is worth watching.
Citizen Garden Episode 11: Whither Ma.gnolia? from Larry Halff on Vimeo.
I appreciate Mr. Halff’s candor. There are a lot of lessons to be learned here. The first of which is entities on the web might not be what they seem.
On the Internet nobody knows you’re a dog. It is easy and tempting to project an image of being an being a greater entity than a company really is. I got started with working with the web in collaboration with an Australian tie-dyer who was obsessed with keeping the world from knowing that his apparel firm was a three person drop ship operation consisting of him, my wife, and me. It made me uncomfortable then and skeptical now. As pointed out in the interview, there are probably countless other web services that are as small and as shaky as Ma.gnolia.
This leads to the inevitable conclusion that our data in these cloud Social Networking Apps may be considerably more vulnerable than we can imagine. We need ways to backup our important data housed by these services. I have found some leads in this area and I am actively pursuing them. I hope to report some possible solutions in the near future.

February is winding down in a few hours and many are awaiting Elgg 1.5. Whether or not they make the projected February isn’t important if you consider what the Curverider team has achieved in there progress to a much inproved social networking platform.
Elgg 1.2 was released in Decenber with Revision 2515. As of today, in the space of 2 months, they have committed 485 revisions to the code in their Subversion repository–an absolutely astounding feat!
Having tested Elgg 1.5 myself, I can tell you that its release is very close. The developers are determined to make this release as smooth and as free of bugs as possible. From what I can see remaining issues are largely minor.
I look forward to the release very soon. I am also a firm believer that it is better to delay a release than to push it out the door before it is the best it can be! Those who simply cannot wait can always check out the latest version in the Elgg repository. The usual caveat applies: don’t run trunk on a production site.

Some of my colleagues and I have been looking ways to implement Data Driven Instruction (DDI), one of the components of the educational reform being implemented by NYSED’s Race to the Top. We had looked into packages such as LinkIt, but these comprehensive services are only interested in working with schools rather than individual teachers. [...]

I recently found another social networking server app through Twitter. As we know Ning recently changed its terms of service and is no longer offering free social networks. This sent a wave of panic throughout the educational technology community, accustomed to having “free” apps at their disposal. People immediately sought alternatives to Ning. Of course [...]

This is one of a number of posts exploring multimedia learning. I have been reading research on this topic with an eye toward improving my presentations and other multimedia instructional material. Here are earlier posts in order of creation: Text and graphics in Multimedia Presentations Multimedia Researcher Mayer on Slideware Graphics in Instructional Presentations In [...]

As I grapple with research trying to improve my instructional presentations, I have learned about Richard Mayer’s assertion that people learn better with words and graphics than just words alone. As a result, I have been investigating information about the role of graphics in learning. One natural extension of the reading that I have done [...]

Jim Groom just got me fired up again. Groom, in conjunction with Brian Lamb, wrote an important article in Educause entitled Never Mind the Edupunks; or, The Great Web 2.0 Swindle. The article laments the corporatization of Web 2.0 in education. The authors acknowledge the appeal and power of free online services offered by Google and [...]

The animated Chinese timeline shown my previous blog post was a demonstration of a workflow using proprietary software to make a stand alone animated timeline. While viewing the timeline several times, I started examining it through the prism of the research on multimedia learning that I have been reading–particularly that of Richard Mayer. One learning [...]

This is a fairly specialized procedure for users of Keynote and TimeLine 3D, both proprietary Mac programs. The important thing is that it results in something that could be a high quality OER. I had a couple requests for a how-to on building a timeline like the one shown below. Bee Doc’s Timeline 3D is [...]

If you have a Flickr account, one of the easiest ways to to contribute open educational resources (OERs) is to Creative Commons license your images. Once you have done so, your photographs will appear on Flickr’s Creative Commons search page according to the license that you have designated. This is quick and simple to do. [...]

In general, teachers love freebies and actively seek them out. These free things range from blogs to web apps to lesson plans. I’d like to challenge teachers to go beyond just consuming freebies to producing them as well. Teachers create great resources all the time in the course of their practice. We could go a [...]

Richard Mayer is one of the leading researchers on the impact of multimedia on learning. However, in his two books, Multimedia Learning and e-Learning (coauthored by Ruth Colvin Clark), slideware is not often mentioned. Multimedia Learning he simply mentions PowerPoint presentations as an example of multimedia. Since I have ben exploring his research as a [...]
