One Fast Mac

I bit the bullet and bought an extra Gb of RAM for my Macbook Pro yesterday, bringing it up to its maximum memory capacity of 2Gb. It’s a pretty fast laptop anyway, but I was finding that when I had a lot of big programs open, and particularly when I was running Windows using Parallels, it would occasionally have a bit of lag when switching between running apps. Not any more…

The extra gig makes a big difference to the way that non-Universal apps run. Apparently there is a fair bit of memory overhead required for Rosetta (Apple’s built-in emulation layer that enables applications written for the PowerPC chip to run on the new Intel-based Macs), and even with the Macbook Pro’s standard gigabyte of RAM it works the machine hard to run Rosetta apps such as Office and Photoshop.

For anyone using a new Macbook or Macbook Pro, I’d suggest seriously thinking about adding that extra gig. I’d say it’s definitely worth it, although you ought to shop around as the aftermarket memory from places like Crucial seem to be much cheaper than buying memory directly from Apple.

Kudos to James Farmer, who runs the Edublogs service. He has outdone himself.

The server was upgraded last week and the new functionality is fabulous. We can now easily embed Flash, Director, YouTube, Google Video, and iFilm files directly into blog posts, which is a greatly appreciated feature. As well as that, he has installed additional WordPress plug-ins which enable us to do a heap of cool stuff, like the “listen to podcast” option through Talkr, and a link to easily add photos directly from your Flickr account, like so.

Thanks James for continuing to make Edublogs (and I’m hoping Learnerblogs too!) better all the time.

By the way, all this funky Web 2.0 spelling of words like Flickr, Talkr, Frappr, etc is making me wonder if I should start spelling my own last name as Betchr?

Window to the World

Even though I’m just outside Toronto, Canada, I just a fun little chat with a Year 7 class at a school in country Victoria, Australia.

Anne Baird is a teacher from this Victorian school. Anne and I have been exchanging a few emails and Skype calls recently to share some blog and wiki ideas. Anne noticed I was online and buzzed me to ask if I’d like to talk to her Year 7 kids. I said yes, and the rest was easy. From my place in Canada, she was able to have my voice and video image magically appear on the board in a little school in country Victoria, and then Ms Baird and her kids were able to chat to me about life in Canada.

We spoke for about 25 minutes, and the kids asked me a bunch of questions about Canada, what it was like, the weather, the food, the people, and so on. Then my daughter – who is in Year 6 here in Canada walked past the computer so I put her on for a chat. Kate told them about school here, what it was like to live in a different country and so on…

Here’s the thing about this… the time taken to organise this event was about 2 minutes. The cost to make it happen was zero. The effort of taking part required a single mouse click on the Accept button.

It made me wonder… why don’t we take more advantage of these technologies in schools? We so often want to expose kids to bigger ideas and to let them ask questions from people who are outside their own little world, and the technology to do this is right here, right now. The technical barrier to using this stuff is ridiculously low. It requires very little special technical skill or know-how, and is not difficult to set up, and costs virtually nothing. We really should be using it more than we do.

And why don’t we? Too often the barrier for real-time collaboriative tools is that school systems block such traffic from their networks. Administrators unthinkingly deny access to collaborative technologies like Skype, MSN, and so on, because they think that if the network enabled kids to talk with people outside the classroom it would be dangerous or distract them from the work they should be doing, so they just turn it off.

But the way I see it, the value of being able to connect to the outside world could be incredibly valuable if we just manage it the right way. Of course you probably can’t just give open Skype access to every kid, but in many school systems the one-size-fits-all approach to online security is so restrictive that it stops anyone, including many teachers, from using these powerful learning tools with their kids.
