ALIPR Captchas

Captchas are so 2007. There are enough good captcha-breaking bots in the wild now that they’re pushing 10-15% success rates at decoding images, and can generate a new attempt every six seconds. Mail systems at Yahoo!, GMail and Hotmail all have been cracked in the past year. And Google’s Blogger service is under seige from spambots creating hundreds of thousands of splogs without human interaction — and they’re doing it through automated captcha cracking.

A new visual authentication system called IMAGINATION, from Penn State’s ALIPR (Automatic Linguistic Indexing of Pictures) program, takes a very different approach. Working with random images rather than characters means the pool of possibilities is not finite (image recognition is far more difficult than character recognition). And the two-part process refines the human requirement further: Find a center, then describe.

Imagination

But while traditional captchas have had problems with accessibility, ALIPR is going to be completely off-limits to the blind. Oh, and it takes up a whole screen, rather than a few hundred pixels2. That sounds like a deal-breaker right there. Or at least a deal-breaker until we get so fed up with being cracked that interaction designers are willing to give up an entire page to make it stop.

Once you solve the captcha, the site invites you to throw your best bot at it. I’m thinking maybe five years before the bots crack this one.

Twitter Found My Phone

Amazing… just took a break from the all-day Journalism and Databases session we’re running, checked for recent Tweets, and there was one apparently from myself:

Hi.i found this phone.could you tell me how to find the owner..

A few Tweets later, messages from Xian Crumlish, Michael Fitzhugh, and Dylan Tweney, pointing me to the source. A block walk and I had the phone again (which I hadn’t even realized was missing until Twitter told me). Thanks so much Good Samaritan Silje for having the brilliance to check my address book and send an SMS Tweet as me, and to alla y’all for helping to track it down.

Xian’s book title is spot on: The Power of Many.

Update: Whoa! This little  dance just got covered on Wired.com’s blog (by Tweney).

Tech Training for Reporters

Another big week of podcasting coming up as we (the Knight Digital Media Center at UC Berkeley) launch a week of training for working journalists in “new media / digital media” internet technologies. This week will be a variant of last month’s workshop – we’ll be working with reporters rather than editors this time around, and tuning the training to suit. As always, the workshop will be peppered with panels and conversations with fascinating experts, and those sessions are open to the public.

Can’t make it to the J-School? Tune in to the podcast series live, or catch archived versions the following week. I’m especially interested in “100 Megabits across the Digital Divide,” with Brewster Kahle of the Internet Archive, but all of the sessions are bound to be worthwhile.

Cal Day 2008

Miles and I had a great time yesterday at Cal Day, UC Berkeley’s campus-wide open house. Miles got to play with a 15 foot python, had cockroaches and stick bugs walking all over him, went fishing for lizards (I remember when my brother and I used to make lizard fishing poles out of car antennas and fishing line), watched his own voice dance on the screen of an oscilloscope, experimented with the Bernoulli principle (a ball floating on a column of air), experienced his first drinking bird, created a miniature earthquake, built an Indian boli, and almost got conked by the physics experiment below – I turned around to get my camera out of its bag and heard a clunk and some gasps – he had been pulling on the steel balls and the whole thing came off the table and wound up around his neck! Fast reactions – he caught the frame with his hands.

Afterwards, went to a musical performance of The Emperor Has No Clothes at the historic Julia Morgan Theater.

Don’t Walk Away in Silence

Note: Despite the date, this is not an April Fool’s post. Can’t believe I have to say that.

“Don’t walk away in silence,” someone spray spraypainted on the wall of a girls school on the lower east side, New York. The school painted over it, of course, and left this note in its place:

The school turned the episode into a teachable moment. “It really gave us a chance to engage in a dialogue with our students.”

The Science of Sleep

60 Minutes, The Science of Sleep — We’re sleeping less than ever:

In 1960, a survey by the American Cancer Society asked one million Americans how much sleep they were getting a night. The median answer was eight hours. Today that number has fallen to 6.7 hours – that’s a decrease of more than 15 percent in less than a lifetime. And from what the scientists 60 Minutes met are finding, we may be putting ourselves in a perilous situation.

.. and we’re paying dearly for it. Test subjects allowed to sleep only four hours per night are able to metabolize sugars at about the same rate as pre-diabetics, and have a voracious appetite. In other words, there may be a connection between cultural sleep deprivation and the obesity epidemic. And of course, memory and mental acuity in general suffer dramatically as well. Not to mention nice-ness (tired people are cranky people).

But what refrain is more commonly heard in the workplace than “I’m exhausted?” We’re compensating for the insane pace of everything by staying up later, perhaps fooling ourselves that we’ll be more productive if we just trim off a few of those hours “wasted” on sleep. But it ain’t natch’l, what we do.

“But you know I find it amazing to see how many people are asleep within five minutes of boarding an airplane at 11 o’clock in the morning. You know, sit down and boom. It shouldn’t happen. A normal adult shouldn’t be falling asleep at 11 o’clock in the morning, minutes after sitting in a small, uncomfortable airplane seat. It just shows that, you know, people are exhausted.”

Ever since Miles was born, I’ve been deep in this pattern, getting by on 5-6 hours/night (7 on a mellow day), day after day, week after week. I used to try and get one full 8-hour night per week, but now even that doesn’t happen regularly. You just get so used to being a zombie, it starts to feel normal. Every now and then you get a full night or something close to it, and the mental clarity is astonishing, this feeling of alertness like you remember from a long-ago life. I swear I’m going to reform, get back on the 8-hour track permanently… but I never do. They say we’d be more productive sleeping more than less – that the increase in sharpness more than compensates for hours lost in sleep. But it’s hard to convince myself of that.

Anyway, it’s well worth the watch (or read).

How many hours of sleep do you average per night?

Tech Training for Journalists

The Knight Digital Media Center has been running workshops providing multimedia skills training to journalists for a while now, but this week marks the start of a program expansion, as we offer our first Tech Training for Editors workshop. Rather than Photoshop, Sound Track Pro, and Flash, we’ll be teaching RSS, podcasting, map mashups, and other essential internet technologies to editors looking to expand the web savvy of struggling newspapers.

I’ve been busy setting up WPMU as a mock CMS for the editors to work on, relying heavily on the PodPress, Twitter Tools, and WP-Flickr plugins. I’ve also got the new Prologue theme installed, to demonstrate how publications can provide Twitter-like services of their own (I’ll be demonstrating it in a mini-session on microblogging).

The mid-day and evening sessions will be webcast as usual, but this time we’re adding a new element to the mix — rather than panning the camera to a screen displaying output from the presenter’s laptop, we’ll be using Vara Software’s Desktop Presenter to mix output from the speaker’s laptop with camera output, directly into our webcast software (knock wood). Tune in!

Duck Butter

Sauces 2008

Ooooooo wEEEEE! Made my “annual” pilgrimage at SXSW to Tears of Joy Hot Sauce Shop in Austin (bottom of 6th street, across from Damn Good Tacos). Since I depleted last year’s 8-bottle shipment easily, ramped it up to 10 this time, plus an assortment of mustards (I loves me my mustards) and a bottle of Salt Lick BBQ sauce for good measure. Came home tonight to a big box full of foam peanuts and bubble wrap, which Miles and I dove into just in time for dinner (chicken sandwiches).

First up: Duck Butter. Mmmmm tasty! But too mild. Followed by Bee Sting, a honey-based habanero sauce. Totally different kind of tasty, but still on the mild side (Amy disagreed). I was looking for some real tears of joy, which I finally got with a big dollop of Lottie’s scotch bonnet elixir. Blinding sheet of pain racing up the plane of my face and I’m in heaven.

SXSW 2008 Recap

Howareyou Just before leaving for Austin last week I caught an article that brazenly wondered “Has SXSWi gone mainstream?,” citing the choice of Mark Zuckerberg for one of the keynotes. What happened to the cutting edge? It’s true nothing really ground-breaking came out of this year’s show, but that had absolutely nothing to do with the conference’s usefulness… or fun quotient.

As usual, I took (and posted) loose notes on most of the sessions I attended. And as usual, there are often two or three sessions you want to see all happening at once. If you realize you’ve stumbled into a clinker, it’s a crapshoot whether it’s going to be worth it to stumble out, walk halfway across the convention center and try for seating in another — but you do your best. The Twitter back-channel helped tremendously… getting bits and pieces of other panels whispered in helped alleviate the feeling that you were missing something big.

Twitterrific Icon Yeah, I fell for the Twitter thing big-time this year (I’m “waxwing,” if you care); remains to be seen whether it will be as fun or as useful outside the context of the show. Twitter was everywhere – at times it seemed like you couldn’t glance at a laptop (must have been 85% Mac, for cripes sake) without seeing someone plotting their tweets. I’m not big into SMS, but between trying to hook up with people and following Twitter feeds, I’ve never done so much texting in my life

Zucker Had the inverse privilege of being present at the Mark Zuckerberg train wreck interview … not to be forgotten. Gossip and armchair analysis of the interview dominated conversations for the next 24 hours until we were all just sick of hearing about it.

Cacherock Got four hours of good geocaching in with mandric on the first day, before badge pick-up. Austin is in love with virtual (no physical box) caches for some reason – I think they just love their history. As a way to discover parts of a new city through serendipity, caching can’t be beat (and I think Milan caught the bug too!) Some pretty creative hides. Thanks Austin!

As for panels… where to begin? The Expression Engine 2.0 demo blew our doors off (coming version fully integrates ORM-based framework CodeIgniter). Jason Fried’s 10 Things We’ve Learned at 37 Signals totally inspiring for the 2nd year in a row. Henry Jenkins keynote an intellectual rollercoaster — tough competition with Kathy Sierra’s Tools for Enchantment (walked out of that one reeling). So many incredible data visualization techniques unwrapped in Data as Art (big implications and challenges for journalists). Went to two scaling sessions: Scalability Boot Camp and Scaling Web Ventures – of the two, the 2nd had more real-world tips, both both full of useful goodies. Interesting web pre-history in The Web That Wasn’t. Still feeling ho-hum about Adobe Air. Building Portable Social Networks attempted to address the coming tower of Babel between SNs, but left us with “We’re in for a world of pain.” Speaking of pain, I felt for the Microsoft guy defending MS Sharepoint against Drupal at the CMS Roundup. More here.

Neil Getting too old for the relentless party scene that is SXSW, now more interested in finding quiet places to talk with old co-workers and friends, but managed to squeak in a couple of good parties. Really enjoyed myself at Opera‘s party at Stubbs, where I spent 20 minutes in the bathroom talking with an Opera engineer who was the spitting image of Neil from The Young Ones. Think Opera is dead/irrelevant? Factoid: Opera currently employs more than 500 people – the mobile browser market is huge, and Opera owns it. Also a great party at the Mexican American Cultural Center (gorgeous architecture, and music by Gruppa Phantasma = Santana + War + 2008; break dancing like you never seen. Managed to get by on 5-6 hours of sleep per night, but couldn’t keep up that pace for much longer (despite official advice to NOT try and pace yourself (the “liver hacks” portion of that session were especially interesting).

Finally made my pilgrimage to the Daniel Johnson “Hi, How Are You?” mural at the top of Guadalupe, en route to lunch at Ruby’s – some of the most amazing brisket and ribs I’ve ever eaten, served up by the pound on butcher paper in a ramshackle wood and corrugated tin building that hasn’t been renovated in 70 years (or something like that). Even beat The Salt Lick (but not by much).

Didn’t take as many photos as in years past, but managed to get a Flickr set up. Once again, it takes something like SXSW to lift us out of the .edu miasma and into the new world. Always worthwhile.

Update: Wow – Check out these SXSW Interactive 2008 Sketchnotes. Gorgeous.
