First is an article talking about the practical implications of CLT on the design of learning. The second are some "recent" (as of 2003) developments regarding CLT. Happy reading! Update: I clarified the second...

Publishing an App Inventor app to the Android Market As I mentioned earlier, my students and I published an Android app to the Android Market. See those links for more information on the background. This post is decidedly technical. First, once we finished the coding process, we packaged the app for to download to the computer. This is an option in App Inventor. This downloaded an .apk file....

New Mac conundrum, help me think this through

Category : General

Hello dear readers, help me think things through, would ya?

I’m going to be getting a new Mac soon, and now that the Stevenote is done and no new computer products were announced, I feel it’s a pretty good time to buy. Here are my two options.

Right now I have an early summer 2006 20 inch iMac. I have a 19″ Dell 1905FPS Monitor next to it providing extra screen real estate. Since the Dell monitor has two inputs, it also serves as a monitor for my Ubuntu server which is running some scripts for me in perpetuitity.

My dad will be getting a new machine so that means I’ll inherit another Dell monitor. Twins!

My thinking is that having two 19″ LCD Screens next to each other both hooked up to a brand new Mac Pro (2 processors) would be the ideal thing. It would fit nicely on my desk and I’d have room to spare.

However, the 3.06Ghz 24″ iMac is also tempting. That means I’d have to move the Dell monitor and make some space and maybe take the other Dell monitor to school.

So, which is it?

Option 1: Two 19″ LCD Screens with dual inputs side by side displaying 2 x 2.8Ghz Mac Pro goodness, or?

Option 2: a 24″ iMac clocking in at 3.06 Ghz with an awkwardly placed Dell monitor off to the side?

It seems the way I’ve written that that my decision is made, but I figure there’s some perspective I’m not seeing, any thoughts?
