what are you teaching these days?

I love the facebook application that lets you see what your online friends are reading. Same goes for the sharing features in amazon.com. A friend (hi Judi!) put in her status message today that she’s prepping for class, which excites her because she’s teaching about Piaget today.  How about ‘teachbook.com’ that lets you see what your academic friends are teaching that week? not courses at the semester scale, but topics…

Design challenge: help the teacher

So, usually I post potential solutions to problems. But this is a problem too juicy to pass up. http://www.43folders.com/forum/2008/01/27/teachers-productivity-hampered-technology-no-love describes a teacher who is reduced to using whiteout to fix worksheets because the district has the machines locked down with none of the needed software. Also note the ancient commercial software the school still runs. What to do? I’m guessing the solution might be a social hack more than a technical one…

digital whiteboards

So, yet again we had somebody suggest taking a digital photo of a whiteboard with their cell phone at the end of a meeting, rather than laboriously copying down the contents.Why not just invent a gizmo that is built into the room to do this task well? CCDs are so cheap now, and I have a few old, semi-broken digital cameras, how hard can it be to make a box that simply attaches to the ceiling in the room and is dedicated to allowing people to share/archive/print their whiteboards? In the old days, this kind of smartboard technology was really expensive, but given our ubiquitous wifi, it seems like a specialized version of a webcam that should be very cheap to produce.One challenge that seems solvable is the optics. Someone should be able to design a little plastic lens that corrects for the keystone effect if the camera is ceiling mounted.  I would have to think through the design implications for how to get this to the right participants and only the right participants. Maybe it just has a certain web address that you go  to, and it gives you a high-res slow speed pic of the board. If you’re security minded, how about just putting a little remote control next to the board, with a green button for “take a pic” and a red button for “erase”, and then only if you go to the correct web address before erasure would you get the digital board image. A console into which you type an email address might also work but would require more hardware. Oh, I know–how about you plug in a USB stick, and it simply dumps the image file directly on the stick when you press a button. No wifi required there, just a cable from the ceiling to the console. Better still–a device where the console is the camera, and sits on the table as an all in one.  Final idea–what if you integrated this tabletop whiteboard snapper into the portable digital projector? So somebody’s infocus projector would also take snaps of the whiteboard for your USB stick. That would be neat.

academic freedom vs. free speech and the Web

Can the web be used to improve the quality of ideas, or is it going to just be a world-wide shouting match of people not listening to one another? Read the rest of this entry »

power play three

Last night, I had the pleasure of seeing Penn State’s solar decathalon house. These guys are brilliant, not insofar as the solutions they propose are all that novel or even so well executed (I’m hoping their design is fully realized, i.e., done, a few short weeks away when the house gets carted off to the National Mall in Washington DC.) The thing that is great is Read the rest of this entry »

power play–two

Today the power went out in four buildings on campus. Not my building. And almost instantly, people were poking their heads out of their offices and cubicles gopher hole style all over my building. Why? Because we are so dependent on a completely centralized functioning grid. Read the rest of this entry »

power play–one

Apologies–I started this post almost two months ago, and now I finish it. But it works because I was just going to post something related anyhow.

Begin old post…
So, this week I was trying to do something about my household energy consumption.

As some may have read, the governor of Pennsylvania is currently locked in a budget stalemate with the legislature because he wants state support for reducing reliance on fossil fuels. But in general, there are no resources here to help those who want to reduce their energy consumption. Read the rest of this entry »

thin pipes and fat files

Why can’t I control how much bandwidth different programs on my computer use?

I’m sitting here in a hotel trying to download my email for a quick check. I have 10 minutes before I have to run. And though my mail usually comes down pretty quickly, and I’m on a halfway decent wifi connection, it’s like molasses. Why? Read the rest of this entry »

where’d that come from?

So I have trained myself to start storing things that I find on the web for future use–who knows when they will disappear. But there’s one important issue: I can’t find out where it’s from if I only have my local copy. Read the rest of this entry »

group ecards

It’s not uncommon for somebody to send a card around the office for get well wishes or retirements… why hasn’t anybody made a group e-card interface? Read the rest of this entry »
