Murphy’s Law of Servers

Wednesday, December 23rd, 2009

Why is that you will also get a tech emergency email 5 minutes before you leave on vacation?

Not 5 minutes before boarding the first leg of my holiday travels I get a message noting that our entire cloud cluster is down. D’oh!

Turns out it was just power, but seriously!

Have a great holiday season.

BT Cluster

Here is the BT cluster racked up. Brings a warm fuzzy feeling to my inner geekdom.

Running a mix of OS X server and Linux VMs that power our blogs, wikis, and moodle. :)

10.6.2 Server with APC cache

Monday, December 14th, 2009

As many are aware there is some funkiness trying to get APC caching working with 10.6.2 Server. After running all over the web, I finally generated the needed apc.so using macports.

If you want to save yourself a ton of trouble , you can try the attached apc.so.

Steps to install:

  1. Download and unzip.
  2. Move to “/usr/lib/php/extensions/no-debug-non-zts-20090626/”
    (Use cli: sudo mv apc.so /usr/lib/php/extensions/no-debug-non-zts-20090626/) this assumes your are in the folder with apc.so
  3. Edit your php.ini file (/etc/php.ini) with the following:
    [APC Cache]
    extension=apc.so
    (***Add additional configuration parameters here***)
  4. Save your php.ini and restart the webserver.
  5. Browse to your phpinfo file on your webserver and check to see if APC is running.

I hope this saves some of you time. I’m really at a lose to why Apple doesn’t correctly install PEAR/PECL so that developers can make the modifications they need.

Can we do this with MS/HS students and text messaging?

Brilliant idea! Imagine being able do this with key vocabulary and other types of basic data. I could totally see HS and MS students loving this.

Tap that phone!

THE Journal 2010 Predictions

Thursday, December 10th, 2009

http://thejournal.com/Articles/2009/12/10/5-K12-Technology-Trends-for-2010.aspx

Sort of lame list….I think mine is better. :)

I think the biggest item missing from this list is open-source, open-source, and open-source. With raging budget deficits across the country educational institutions across the K-20 spectrum are going to be looking hard at open/free alternatives in their upcoming technology adoptions.

I also think that the recession is a nature time for us turn away from capacity building to spending some time developing efficiencies with the technologies we have. I look at the technologies that are available to most educators and would be willing to bet they only tap 25-35% of the capacity of a given device/service/application. You could make huge gains by increasing that efficiency to 45-55% for less than building more capacity.

And even though it develops capacity, I see virtualization really taking off! Their will be growing needs for technology but no money to purchase new hardware. Using VM, institutions will be able to create capacity by tapping unused potential in existing hardware infrastructure.

Again, economic troubles will bring Google Apps up as a viable option.

Educational content providers will figure out a way to provide a more iTunes like way of distributing digital content. This also has the potential to bring down the costs of distribution of instructional materials.

The Blog Ate my Homework

Wednesday, December 9th, 2009

I keep waiting to hear this.

We are just coming into the first critical deadline for our Senior Exit Project Blogfolio pilot. It is only a matter of time before this comes down the pipeline.

Times and technology changes but I bet that teenage procrastination is a constant.
