In my quest to find better ways to deliver training and learning around the world, a suggestion from a colleague has turned into a unique distance-learning solution.

We’ve put about 6 hours of video recordings from our teacher training session onto an iPod Nano in MPEG4 format, and the Nanos are being carried to teachers in countries where Internet connectivity is thin or doesn’t exist.

And we’ve added a couple hundred photos, and videos produced by our first year participating schools.

In a subdirectory on the Nano, accessible from a computer, are copies of various documents that may also be useful to teachers and Project Happiness leaders.

As time goes along, we will add more video, including video from more schools, and more documents that teachers can modify and share. The Nano should be able to hold about 20 hours of video.

The Nano can also drive a regular (NTSC or PAL) television monitor, so it can be used with a group of teachers.

And when everyone is trained, the device can be initialized and then loaded with your own tunes or local video. (We supply a set of backup CDs that can be reloaded onto the Nano from a computer if desired.)

Can’t tell you how many hundreds of hours I spent fiddling around with antenna positions in order to get good reception. In those days they were mostly long wires strung from buildings or trees, but the principle is the same for a mobile phone antenna. It all depends on the direction the antenna’s pointing, the distance from “ground” (actual earth or metal objects below the radio’s antenna) and other factors that are just too hard to predict. And so we “fiddle” until we get it right.

In the case of a mobile phone, which is also a radio transmitter and receiver, the variables are pretty much the same. They include whether you’re holding the phone in your hand or not, whether it’s near metal objects, whether you’re inside a steel or concrete/brick building, and your orientation with respect to the cell you are currently connected to. So when you hear “can you hear me now?” what’s going on is that you and your callee are each adjusting or moving your radio and antenna to get better reception. We have all become amateur radio operators!

Well, let’s just blame it on Twitter. Or on the new iPhone. Or on two clients wanting 70-hour weeks from me all month. Or on processing 4 hours of teacher training videos.

Nah, let’s just blame it on Twitter.

Twitter seems to have taken a big bite out of my blogging energy lately.

I primarily use Twitteriffic on my iPhone to both follow and to create new tweets, but I also love Twitterfox (a plug-in for the FIreFox browser) if I’m at a computer (it just pops up a little panel showing the most recents, and lets me quickly twipe a new tweet whenever I feel the need.

But why do I even bother with Twitter? - because I get stoked with a dozen new ideas every day! In the old days, “kids” used Twitter to vacuously and narcissistically communicate “I’m having breakfast” or “I’m on the bus” or “I’m at the coffee shop.” But somehow a large number of busy people realized that not only was this a waste of a good communication medium, but something better could actually be done with it - and now what we do is communicate concepts, places, activities and ideas of interest to our group. Someone might be experiencing writer’s block and need inspiration and put out a call for help that explains the concept she’s working on, and get back a half dozen interesting tangential ideas! Another might have returned from a trip and posted photos - and will put up a tweet pointing to the photos. Someone else will be at a conference and will tweet about each speaker’s primary concept.

You have to carefully pick who you “follow” (whose tweets you subscribe to) on Twitter, but once you have your list tuned well, you have constructed a channel that lets you really stay in touch with the ideas and activities that will surface as blog posts and news in the next 24 to 48 hours. And you get a real boost from knowing what your friends and colleagues are working on and thinking about.

Clear is the program that pre-screens travelers, collects biometric data, puts this on a smart-card (embedded processor+memory, not RFID) and then allows travelers at a few high-traffic airports to go thru a quick-screen line (including a retinal scan to verify ID) rather than stand in lines with un-pre-screened passengers. They still get screened, but they “jump line,” sometimes skipping ahead of a hundred or more who are waiting in the regular lines.

Almost predictably, a laptop containing the data of 33,000 applicants (not participants) was stolen from a secured room at SFO. A spokesperson says “it [the laptop] was protected by two passwords” - but that doesn’t tell us whether the information was encrypted, how secure the encryption was, nor why sensitive information would be on a computer that is portable (and thus easy to steal) computer. (It is pretty easy to bypass password security unless the data is also encrypted - I’ve done it myself more than once on client computers where they’ve forgotted a password - takes about 10 minutes.) And we don’t know what other types of information might be on this computer.

Clear is run by an independent contractor under TSA oversight.

One interesting outcome was the comments ABC7 (San Francisco TV) collected - for instance “Clear customers say the sooner the changes are made the better, although no one seemed too worried about the security breach. ‘You’re information is everywhere and people volunteer their information on places like Facebook, on Twitter, on MySpace and stuff,’ … a traveler.” I don’t actually think they understand the breadth of information that was reported to be on that computer - this is information that is to be used in a security screening, not just social security numbers (though those may not have been present), and presumably known only to the applicant - a far broader range of confidential information than most other systems would hold. It just shows that people are resigned to living in a transparent world - probably until they are directly affected, of course.

KTVU reportage on this same story. KTVU also reports “The TSA requires RT service providers and sponsoring entities to encrypt all files containing participants’ sensitive personal information. Noncompliance with such requirements can result in actions including suspension of a program and possible civil penalties.” I have not verified this, and we don’t know the type of encryption that’s required - for instance a password on a ZIP file is probably not very secure, while encryption with a 2048-bit RSA key would be a lot harder to crack.

I earlier reported on “odd” scanning of my driver’s license at a regional airport, to which TSA replied (in comments on my blog) that it was (probably) an ultraviolet light (blacklight) being passed over the license to be sure it was genuine (this process reveals the “holographic” images in the license’s plastic layers). As I said, I was concerned that any scanned information that passed into a laptop computer allowed potential theft of this confidential information. Well, I guess this Clear incident further emphasizes that security information has no business being stored on a computer that can be physically stolen.

3G phones are generally capable of being linked or “tethered” to a computer via bluetooth or USB in such a way that the computer can use the phone as a connection to the Internet. I used my Moto RAZR that way for several years, paying for a $20/month data plan. Although tethering provided between 40k and a maximum speed of 80k (bits per second) or roughly 2x phone line speeds, it was nevertheless really handy in those moments when I was far from free wi-fi or phone lines. And I had long ago dropped my AOL dial-up service, so dial-up wasn’t really an option.

And since using the iPhone to connect a computer to the net is a violation of AT&T’s terms of service, none of us ever thought that such an app would be sanctioned and appear in Apple’s online store. Obviously it would be done for “jailbreaked” iPhones, but probably not for those remaining solidly in the AT&T fold.

But the app did appear. Then it disappeared. Then it reappeared. Oof. Was it Brigadoon? Or was it the Flying Dutchman?

So when the app was visible online, this afternoon, I quickly plunked down $10 and downloaded Netshare to test.

Turns out that it doesn’t really tether the phone. Instead, what it does is serve as a SOCKS proxy for your computer, which means the computer can access web sites (including secure HTTPS) thru the phone’s 3G or EDGE connection. That’s really handy at those times when nothing else’s available, but it’s not quite everything that we need. You couldn’t get email onto your computer thru this app, for instance. (At least I haven’t figured out how to.) But you could do webmail. And anyway, you can do email on the iPhone if you have your accounts set up right.

So I’m happy with it as an emergency standby.

Technically the way it works is 1) you configure your Mac to create an ad-hoc Wi-fi network; 2) you configure the iPhone to join that network; 3) you bring up Netshare on the phone, which runs a SOCKS proxy on port 1080, available to any device that’s on the ad-hoc wi-fi network, and voila the Mac has access to HTTP and HTTPS sites thru the proxy software running on the iPhone. The access out “the other side” is via 3G or EDGE.

Slick, and unexpected, and a violation of the TOS, but still this is going to save my neck at some point in the future.

Then came the iPhone. And rich (HTML) email entered the picture for mobile devices. And richer and longer in-game responses from players. (SMS is only 160 characters, while email doesn’t have this limit, and thus is so much more fun.)

Well, over time that changed. Sometimes text messages are delayed for a substantial time (can tale hours), and our games are real-time so any delay beyond say one minute is a catastrophe. And then more and more phones became capable of sending text messages to email addresses - it had only been T-Mobile at first, and now it’s most phones. Today, at least 50% of phones in the US are capable of sending/receiving email, even thru the SMS mechanisms (there is an SMS-to-email interface on all systems).

So we’ve made a number of improvements in our games that permit play from regular email as well as mobile email-capable devices like phones, PDAs and smartphones.

And it looks like 2008 may be the year that we’ll develop more of these new, rich street games based on HTML email, and still played from mobile devices like the iPhone.

Yesterday (July 31st) we sat down and planned the trajectory for the next few such experience for YBCA - this is going to be fun. Watch for more on this as we announce the next YBCA game (October).

Apple Computer had already announced that there are problems with power bricks for the old PowerBook and iBook computers (now officially discontinued) - the small cord coming out of the brick (carrying low voltage) is under a lot of stress and strain, and can short out right where it comes out of the brick’s case. So I was kinda ready for this intellectually. My brick is carried in my backpack almost every day, with the cord wound around the brick, and I can attest that the stress at the point where the cord comes out of the body of the brick hasta be a factor in weakening the cord, even though I’m always careful. Over the course of four years, being coiled and uncoiled every day, that’s thousands of flexions we’re talking about.

So on Saturday, I was sitting on the floor using my computer, with an external LCD monitor attached to it (also sitting on the carpet), and noticed a plume of smoke rising from the top of the monitor. I thought a little bug had probably crawled into the monitor and been tazered to death by a high-voltage supply. But I noted the acrid electrical/plastic smell of the smoke…which didn’t really smell like delicious fried bug.

It was only on Sunday that I put 2 + 2 together after I took a look at the cord on my power brick. The brick had been sitting beneath the LCD monitor, and the small cord on the “low-voltage” side of the brick was burned to a crisp. The smoke had nothing to do with the monitor - it was the cord on the power brick. No wonder I smelled plastic melting! I had lived thru a tiny electrical fire.

I looked up a replacement power brick online (I got one for an ancient iBook a few months ago), and found that the cost of replacement would be around $90 for an Apple-branded power supply. Bad luck.

So, being an old amateur radio operator (since I was 12 as K9KYI, now W6SNP since 1976), and having no fear of the soldering iron, I dug out my wire cutters, strippers, solder and soldering iron, and ripped apart the silicone sleeve where the cord connected to the body of the brick. Used to, I should say, because now it was a blackened mess of tiny twisted metal wire and melted/charred plastic insulation.

Luckily, I found the manufacturer had squirreled away a twist of cord inside the brick itself (an internal “strain relief” knot), which I untangled, and was able recover about an inch of good wire. I cut, stripped and soldered. Then I taped it all together with black electrical tape acting both as glue and insulation, and wrapped the same black tape around the body of the brick to hold everything in place. (I never did complete the disassembly of the brick - turns out I only needed to get into the body thru the hole where the wire enters. And the power supply now works as well as it ever did.

So $0.02 of solder, electricity, and a lot of futzing around, had saved me $90.

The only problem I anticipate is that the adhesive on the in-side of the tape may begin to melt and ooze because the brick does get warm (but not hot) after a few hours of operation. And mine is in operation about 16 hours every day.

Others have reported similar problems, and have made similar repairs to the one I made. Apple forums are full of reports of smoking cords. So this isn’t unusual. But I’m very happy I avoided setting the carpet on fire.

For offline blogging from a laptop computer, I already use Ecto, which gives me substantial freedom in that I can create new posts even when not connected to the net. Having the ability to write on the iPhone whether online or off might be fun.

My first impression is that this tool will work fine as long as you don’t want to include any fotmatting, because it’s really a pain, on the iPhone’s touchscreen keyboard to get to the < and > characters - it requires several taps for each. So it’s probably only viable for text with a photo or two interspersed. For many people that’ll be OK, but it’ll be somewhat limiting for me.

I am, however, finding that a one-finger typing method while allowing the phone to correct the typos really is quite excellent! And the “fatter” I make each tap on the screen, the more accurate the algorithm seems to be.

I’ve had the app just quit out from under me several times, but I haven’t lost any data, so it’s inconvenient but not fatal. And I know it will get better with the next version.

This app looks like a keeper.
