Sure; when there are easy ways to send text messages around on little tiny devices, students will cheat. I wonder how you keep that from happening in the Steve Mann vision of always-on cyborgs? You’d have to actively jam the devices, since communication inside the classroom is as much a problem as access to the Internet. Or just retool to an open book system, which might be much better.
The Internet was hit by this attack last night. Parties unknown exploited the MS SQL vulnerability to launch a distributed denial of service attack which took down much of the Internet, as per this post. Meanwhile, I’d been mulling over a recent security alert that discusses a vulnerability close to the heart of the HTTP protocol. Once again, Vernor Vinge got it pretty much right. His future computer nets weren’t something you jacked into, they were a vast network full of legacy code and unexpected consequences. Sounds about right.
But I had another thought, which I think was triggered while I was driving around with my brother looking at all the pretty 802.11b networks the other day. What about a non-mobile collaborative blog? What if I stuck a wireless access point somewhere in Harvard Square, and set up a weblog for people using the access point, and only let people post to it if they were coming from the access point’s IP?
That’d be pretty keen. It’d be an ad-hoc collaboration, but it would be tied together by a given community. I’d love to see all the variations on how people perceived the Square (or wherever this was located). You’d probably want to set up a web proxy, so that you could display a little info about the weblog to anyone using it. Otherwise people would never figure out that they could post. It’d be neat if you could do a sidebar with some information on the people using it, but I can’t think of anything that wouldn’t be somewhat invasive of privacy. “Last Ten Mobile Google Searches?” Maybe, maybe.
They say you can’t solve social problems with software, but I believe that you can shape social interactions with technology.
Since I’ve been boosting the Sidekick excitedly for the last few days, I ought to let people know about a caveat. If you use Keyguard mode, sometimes incoming calls won’t ring, which means you’ll miss the call unless you happen to be looking at the screen when the call comes in. (Keyguard mode automatically locks the screen after a given period of inactivity, to prevent accidental calls.) If you turn Keyguard mode off, no problems.
I’m sort of fooling around with a side project, with the intent of using Movable Type as a general content management system, and I came up with something that I thought was kind of clever. I wanted a list of offsite links on the front page, and I thought it might be nice to allow other blog authors to add links, but I didn’t want to give full template modification access. Thought about it a while; came up with a solution.
I created a category named “Offsite Links” and added a bunch of entries in that category. Each entry had the name of the destination site as the title, and the URL for the site as the entry body.
Then I added the following MT template code to the front page template:
<MTEntries sort_by="title" sort_order="ascend" category="Offsite Links">
<a href="<$MTEntryBody convert_breaks="0"$>"><$MTEntryTitle$></a><br/>
Boom. Quick and easy link list effect. Note that this would also be a way to maintain a blogroll if you didn’t want to use blogrolling.com.
So: why doesn’t my web browser detect unlinked URLs in a page and turn them into links for me? Sure, sure, it should be an option I can turn off. However, I want to stop cutting and pasting stuff like http://www.meyerweb.com. For that matter, I wouldn’t mind if it picked up any hostname beginning with www — let it catch www.meyerweb.com too.
Catching anything that registers as a domain name might be a bit much. On the other hand, perhaps it might be worth doing a DNS lookup and converting anything that returns. In a very optimistic world with sufficient computing power, you could do the DNS lookup, check port 80, and if there’s something responding then do the conversion.
Hell, humans are slow readers. Go ahead and fetch the page and cache it in case that’s where I want to go next. At this point you ought to be prefetching allll the links, though.
And they say there’s no reasonable use for more bandwidth. It is to snicker. You just keep precaching further and further out the more you get.
Utterly elite. Amazon is now offering the Sidekick for fifty bucks after rebate. And, come to think of it, if you use Share the Love I bet you get the full 10% of $250, which would make it an additional twenty-five bucks off, assuming one of your friends takes advantage of the deal. Um. That would mean you’re getting a Sidekick for twenty-five bucks.
Twenty-five bucks. It’s a cell phone, an email station, a web browser, an AIM client, and a crappy camera. Plus all the essential organizer functions. But hell, even if you can’t share the love, it’s still just fifty bucks.
I cannot believe that this thing became commodity hardware so quickly.
I’m at the Apple Store watching the Macworld Expo keynote broadcast. Lots of audience shots onscreen right now, so I got into the spirit of the thing and snapped two pics, visible at Hiptop Nation. I’ll update this if Jobs says anything interesting.
My, this is an excited crowd locally. Steve can’t hear you clapping, you know.
OK, an iPod jacket with controls on the sleeve is cool.
More integration between the iApps is pretty cool. Updates for all of ‘em, it sounds like… ah, except iTunes, which had hiden features in 3.0. iPhoto 2, with integration plus really slick retouch. Wow, very solid integration.
iMovie has chapters, heh. Better audio editing, good. New UI! About time. Integration with iTunes is slick. I wonder if that service is available to other apps? Pans over still photos, with iPhoto integration as a photo source.
iDVD 3, again with integration. Direct export from iMovie into iDVD. Chapters! 24 new themes. Hugely slick menu building.
The whole schmear is now named iLife, available 1/25, free with new Macs. All still free exceot iDVD, which comes as a bundle with everything else in the suite for $49.
New browser! Safari. Very fast, and yeah, they benchmarked it vs. Chimera. Integrated Google. Ew, brushed metal UI. He likes his bookmark implementation but it doesn’t seem so innovative. Still, it’s very fast and looks like a solid entry-level browser. Supports XHTML. It’s KHTML-based. Yeah, he’s putting all the improvements back into the community. Free beta download as of now.
Keynote — new presentation app. Steve’s been using it to do keynotes for a year. I guess we’re well into the screw Microsoft portion of the keynote. Yep, cause it imports Powerpoint. And exports. Nice. Cost is $99, available today.
New portable? Sort of, 17” Powerbook. Sexy! Thinner than the old model, too. 1440×900 display. Look up the specs on apple.com; it’s worth it. 802.11g! And a new Airport! Yeah! $199 for the new Airport. Insane.
One more thing… a new 12” Powerbook, which is the amallest notebook in the world. Cute.
