  Please support me in the 2010 Ride to Conquer Cancer - last year we were able to raise $6.9 million for the Alberta Cancer Foundation - hopefully we can raise even more in 2010!

David Wiley just published a draft of his next paper, “Using O2 to Overcome Learning Objects Limitations“. Interesting read, as usual, and he makes some good points re: granularity and reusability.

Some of the things he talks about are already in the plans for CAREO (i.e., being able to use anything as a learning object, regardless of design and format, and have it Just Work. I’m planning to extend CAREO’s media playing capabilities to better wrap various media files and automate the reporting/tracking of status in order to feed data back into CAREO, similar to what an LMS would do with SCORM).

Someone in Trenton, New Jersey, is hammering the RSS feeds in CAREO. Sending fresh request for a bunch of RSS feeds every minute or two. They’re currently running over 70 simultaneous sessions in CAREO, but this has been over 300 in the last few days. They’re not running a webserver on their IP address, so I’m guessing it’s a desktop aggregator set to “stun”.

I don’t think they mean to be sending all of these requests, but this really underscores the need for caching RSS feeds (either at the aggregator/displayer or at the repository level).

We’re looking at migrating to a new server in the next while, which should help alleviate some of this load.

I just checked WOMonitor for the deployed version of CAREO, and it says we’ve got 75 simultaneous users hitting it now. Yesterday, we had over 200. 30,000 hits in a week.

Something’s up… I wonder who’s using it lately? It looks like everyone is hitting it as “Guest”, so there isn’t any login data to tell anything. Time to crunch the Apache access log…

UPDATE: I combined all logs from careo.ucalgary.ca into a single 88MB log file to crunch. This might take a while…

UPDATE 2: Some interesting gems in the access log. Looks like the CAREO install package has been downloaded almost 40 times. Wow. It also looks like people spend much more time on CAREO than I was guessing (many folks spend over an hour!) Processed access log is available here.

I’ve been a little busy lately, largely because I had to break the CAREO 3.x development freeze to meet some requirements for the MedCIS integration. That project is coming along well now, but there are still a few more tweaks I’ll need to do in order to deliver it as required in the timeline they need.

Basically, this means I have been forced to ignore CAREO/Extreme, and let King run wild with it. Actually, that’s probably a good idea, anyway. He seems to do his best work that way. It’s going to be cool to see what he’s come up with when I can finally come up for air.

Posts will likely be few and far between, at least until I get the lion’s share of modifications in place.
