A New Lease

Friday, December 30th, 2011

I am happy to announce that I have renewed the lease on this domain for another three years, so the blog will have a home until December 2014 at least.

Wow, that seems so far away. I remember how far away December 2011 felt in December 2008. Now, with the Twitter and the Facebook and the iPads and the kids these days with the hair and the music, I wonder if, three years from now, there will still a place for an old-fashioned blog like this one.

Or will there be something completely different?

Earthquakes, Hurricanes, Floods, and Tornadoes

Sunday, August 28th, 2011

Okay, so I missed the riddle this week. I do apologize, but I’ve been constantly besieged by natural disasters of biblical proportions. Sort of.

I was actually in Virginia for the earthquake. I’ve spent the last week vacationing with my family, visiting Jamestown and Williamsburg and the like. On Tuesday, we were at Busch Gardens, and when the group split into different factions, I took the opportunity to set off on my own for a while. I went to go see the Pirates “4-D” movie. A “4-D” movie is like a 3-D movie, except they shake your seat and squirt water at you at appropriate moments in the film. It has nothing to do with the fourth dimension, but it’s fun all the same. At one point, the whole theatre shook from side to side, which I thought was pretty cool, but I later learned that I was actually at the epicenter of a 5.8-magnitude earthquake. It even kind of fit with what was going on in the movie, so I just enjoyed it as part of the show.

After I left the theatre, I ran into my nephew Ian (age 7), accompanied by Dave, a family friend. Dave told me that there had been some kind of earthquake, and that all of the rides were shut down. I assumed that this was a story Dave told Ian to get a break from the roller coasters, so I gave him a knowing smile and went along with the charade. It’s worth noting that, at this point, I had both felt the earthquake and had been told there was an earthquake, and still I did not know there had been an earthquake.

Pretty soon, however, it became hard for even me to stay in the dark, as reports of the unusual phenomenon spread rapidly. It stayed big news for a day or two, but was just as quickly overshadowed by news of an impending hurricane. Hurricane Irene was expected to sweep up the Eastern seaboard and hit New York City by Saturday night. I decided to cut my trip short a day and head back home a bit early. My train was delayed a bit because of flooding below Washington, D.C., but my trip was largely uneventful and I made it back to New York City in time to do some grocery shopping and put my earthly affairs in order.

As I settled in for a grocery-enhanced night of a Kill Point marathon sporadically interrupted by checking online weather maps, I learned of an impending Tornado Watch for New York City. Really?

Anyway, there was no tornado, and not even really a hurricane. Irene was downgraded to a tropical storm before it hit here, and even by that standard, it was pretty mild. I had no interruptions of power or Internet, and could only occasionally hear the rustling of wind outside my window. I did make it through the entire series of The Kill Point, which was about a hostage standoff in a bank, so that was pretty exciting, but that was about it. I can’t say I’m disappointed, but I’m not feeling all that relieved either.

Mostly, I’m disappointed that I missed a riddle, which usually means I’ve been neglecting the blog for too long. I think I’m about ready to return. This week, I survived earthquakes, hurricanes, floods, and tornadoes, so I’m feeling pretty unstoppable. That’s right, Mother Nature, if you want a piece of this, next time you best bring a FREAKIN’ VOLCANO.

Feel free to post relevant quotes from King Lear in the comments. The Shakespeare Teacher is back.

Blog Log

Tuesday, May 3rd, 2011

Last week, I participated in a blogging project sponsored by the Shakespeare Birthplace Trust, who encouraged bloggers to post about the influence Shakespeare has had on our lives. They’ve linked up all of our contributions on one page, and it’s worth checking out. Whether you’re a fan of Shakespeare or not, it’s exciting to read people who are passionate about something writing about how they became passionate about it.

Also, be sure to check out this fantastic song parody from Bardfilm. I missed it among all the birthday excitement, but found again via a nod from the Shakespeare Geek.

In post-birthday blogging news, I’ve been asked to write a monthly post on using data for school improvement for both the company I work for and our partner organization. If you want to get a glimpse into what I actually do for a living – anagramming passages from Shakespeare doesn’t pay what it should – check out my first installment here or here.

Digital Shakespeare Update

Saturday, March 19th, 2011

I met with my middle-school classes on Thursday. They have finished reading the plays, and we were able put together plans for our Digital Shakespeare projects. Plans may change, and who knows what will happen as we head into test prep season, but here is where we have decided to go by the end of the year.

6th Grade The 6th grade class has decided to retell the story of Antony and Cleopatra via Cleopatra’s Facebook page. We are currently discussing what that will look like on our discussion forum, but some of the ideas discussed include status updates, wall posts, photos, and video snippets of students performing scenes from the original play that might have been “uploaded” by characters. We even have a student who knows how to create a mock-up Facebook page when all of the other work is done. This project has a lot of potential! “Marc Antony has changed his relationship status to Married. Dislike!”

7th Grade The 7th grade class is doing a stage production of Macbeth. The plan is to film each scene and create a website with embedded videos, along with student writing about the play and emendations linked from the text. Both teacher and students know this is a very ambitious project, but they have made a commitment to put the time in. If they do, this project will be phenomenal. If they don’t, or if circumstances intervene, it will be my job to make sure the end result does honor to the work they were able to put in. This is similar to a project I did with fifth-grade students years ago, but these students are a little older and the technology is so much better now. I really hope this happens.

8th Grade The 8th grade class will not be available to me much after testing season, since they typically get pulled out for various senior-related activities throughout June, but I think our idea is quite manageable in the time we have left. The students want to create a trailer for a non-existant movie version of As You Like It. Students are currently watching real movie trailers (which are easily accessible online) to notice what features they have in common. This will be one of those movie trailers you see in the theatre that tells you the whole story of the movie, so the final product will respect the play and demonstrate student comprehension as well.

I’ll continue to post updates about the projects here, and hope to share the final projects here as well. Needless to say, I’m very excited by the possibilities! Stay tuned…

It’s a Poor Workman Who Blames Yogi Berra: Artificial Intelligence and Jeopardy!

Wednesday, February 23rd, 2011

Last week, an IBM computer named Watson beat Ken Jennings and Brad Rutter, the two greatest Jeopardy! players of all time, in a nationally televised event. The Man vs. Machine construct is a powerful one (I’ve even used it myself), as these contests have always captured progressive imaginations. Are humans powerful enough to build a rock so heavy, not even we can lift it?

Watson was named for Thomas J. Watson, IBM’s first president. But he could just as easily have been named after John B. Watson, the American psychologist who is considered to be the father of behaviorism. Behaviorism is a view of psychology that disregards the inner workings of the mind and focuses only on stimuli and responses. This input leads to that output. Watson was heavily influenced by the salivating dog experiments of Ivan Pavlov, and was himself influential in the operant conditioning experiments of B.F. Skinner. Though there are few strict behaviorists today, the movement was quite dominant in the early 20th century.

The behaviorists would have loved the idea of a computer playing Jeopardy! as well as a human. They would have considered it a validation of their theory that the mind could be viewed as merely generating a series of predictable outputs when given a specific set of inputs. Playing Jeopardy! is qualitatively different from playing chess. The rules of chess are discrete and unambiguous, and the possibilities are ultimately finite. As Noam Chomsky argues, language possibilities are infinite. Chess may one day be solved, but Jeopardy! never will be. So Watson’s victory here is a significant milestone.

Much has been made of whether or not the contest was “fair.” Well, of course it wasn’t fair. How could that word possibly have any meaning in this context. There are things computers naturally do much better than humans, and vice versa. The question instead should have been in which direction would the unfairness be decisive. Some complained that the computer’s superior buzzer speed gave it the advantage, but buzzer speed is the whole point.

Watson has to do three things before buzzing in: 1) understand what question the clue is asking, 2) retrieve that information from its database, and 3) develop a sufficient confidence level for its top answer. In order to achieve a win, IBM had to build a machine that could do those things fast enough to beat the humans to the buzzer. Quick reflexes are an important part of the game to be sure, but if that were the whole story, computers would have dominated quiz shows decades ago.

To my way of thinking, it’s actually the comprehensive database of information that gives Watson the real edge. We may think of Ken and Brad as walking encyclopedias, but that status was hard earned. Think of the hours upon hours they must have spent studying classical composers, vice-presidential nicknames, and foods that start with the letter Q. Even a prepared human might temporarily forget the Best Picture Oscar winner for 1959 when the moment comes, but Watson never will. (It was Ben-Hur.)

In fact, given what I could see, Watson’s biggest challenge seemed to be understanding what the clue was asking. To avoid the complications introduced by Searle’s Chinese Room thought experiement, we’ll adopt a behaviorist, pragmatic definition of “understanding” and take it to mean that Watson is able to give the correct response to a clue, or at least a reasonable guess. (After all, you can understand a question and still get it wrong.) Watching the show on television, we are able to see Watson’s top three responses, and his confidence level for each. This gives us remarkable insight into the machine’s process, allowing us a deeper level of analysis.

A lot of my own work lately has been in training school-based data inquiry teams how to examine testing data to learn where students need extra help, and that work involves examining individual testing items. So naturally, when I see three responses to a prompt, I want to figure out what they mean. In this case, Watson was generating the choices rather than simply choosing among them, but that actually makes them more helpful in sifting through his method.

One problem I see a lot in schools is that students are often unable to correctly identify what kind of answer the question is asking for. In as much as Watson has what we would call a student learning problem, this is it. When a human is asked to come up with three responses to a clue, all of the responses would presumably be of the correct answer type. See if you can come up with three possible responses to this clue:

Category: Hedgehog-Pogde
Clue: Hedgehogs are covered with quills or spines, which are hollow hairs made stiff by this protein

Watson correctly answered Keratin with a confidence rating of 99%, but his other two answers were Porcupine (36%) and Fur (8%). I would have expected all three candidate answers to be proteins, especially since the words “this protein” ended the clue. In many cases, the three potential responses seemed to reflect three possible questions being asked rather than three possible answers to a correct question, for example:

Category: One Buck or Less
Clue: In 2002, Eminem signed this rapper to a 7-figure deal, obviously worth a lot more than his name implies

Ken was first to the buzzer on this one and Alex confirmed the correct response, both men pronouncing 50 Cent as “Fiddy Cent” to the delight of humans everywhere. Watson’s top three responses were 50 Cent (39%), Marshall Mathers (20%), and Dr. Dre (14%). This time, the words “this rapper” prompted Watson to consider three rappers, but not three potential rappers that could have been signed by Eminem in 2002. It was Dr. Dre who signed Eminem, and Marshall Mathers is Eminem’s real name. So again, Watson wasn’t considering three possible answers to a question; he was considering three possible questions. And alas, we will never know if Watson would have said “Fiddy.”

It seemed as though the more confident Watson was in his first guess, the more likely the second and third guesses would be way off base:

Category: Familiar Sayings
Clue: It’s a poor workman who blames these

Watson’s first answer Tools (84%) was correct, but his other answer candidates were Yogi Berra (10%) and Explorer (3%). However Watson is processing these clues, it isn’t the way humans do it. The confidence levels seemed to be a pretty good predictor of whether or not a response was correct, which is why we can forgive Watson his occassional lapses into the bizarre. Yeah, he put down Toronto when the category was US Cities, but it was a Final Jeopardy, where answers are forced, and his multiple question marks were an indicator that his confidence was low. Similarly cornered in a Daily Double, he prefaced his answer with “I’ll take a guess.” That time, he got it right. I’m just looking into how the program works, not making excuses for Watson. After all, it’s a poor workman who blames Yogi Berra.

But the fact that Watson interpreted so many clues accurately was impressive, especially since Jeopardy! clues sometimes contain so much wordplay that even the sharpest of humans need an extra moment to unpack what’s being asked, and understanding language is our thing. Watson can’t hear the the other players, which means he can’t eliminate their incorrect responses when he buzzes in second. It also means that he doesn’t learn the correct answer unless he gives it, which makes it difficult for him to catch on to category themes. He managed it pretty well, though. After stumbling blindly through the category “Also on Your Computer Keys,” Watson finally caught on for the last clue:

Category: Also on Your Computer Keys
Clue: Proverbially, it’s “where the heart is”

Watson’s answers were Home is where the heart is (20%), Delete Key (11%), and Elvis Presley quickly changed to Encryption (8%). The fact that Watson was considering “Delete Key” as an option means that he was starting to understand that all of the correct responses in the category were also names of keys on the keyboard.

Watson also is not emotionally affected by game play. After giving the embarrassingly wrong answer “Dorothy Parker” when the Daily Double clue was clearly asking for the title of a book, Watson just jumped right back in like nothing had happened. A human would likely have been thrown by that. And while Alex and the audience may have laughed at Watson’s precise wagers, that was a cultural expectation on their part. There’s no reason a wager needs to be rounded off to the nearest hundred, other than the limitations of human mental calculation under pressure. This wasn’t a Turing test. Watson was trying to beat the humans, not emulate them. And he did.

So where does that leave us? Computers that can understand natural language requests and retrieve information accurately could make for a very interesting decade to come. As speech recognition improves, we might start to see computers who can hold up their end of a conversation. Watson wasn’t hooked up to the Internet, but developing technologies could be. The day may come when I have a bluetooth headset hooked up to my smart phone and I can just ask it questions like the computer on Star Trek. As programs get smarter about interpreting language, it may be easier to make connections across ideas, creating a new kind of Web. One day, we may even say “Thank you, Autocorrect.”

It’s important to keep in mind, though, that these will be human achievements. Humans are amazing. Humans can organize into complex societies. Humans can form research teams and develop awesome technologies. Humans can program computers to understand natural language clues and access a comprehensive database of knowledge. Who won here? Humanity did.

Ken Jennings can do things beyond any computer’s ability. He can tie his shoes, ride a bicycle, develop a witty blog post comparing Proust translations, appreciate a sunset, write a trivia book, raise two children, and so on. At the end of the tournament, he walked behind Watson and waved his arms around to make it look like they were Watson’s arms. That still takes a human.

UPDATE: I’m told (by no less of an authority than Millionaire winner Ed Toutant) that Watson was given the correct answer at the end of every clue, after it was out of play. I had been going crazy wondering where “Delete Key” came from, and now it makes a lot more sense. Thanks, Ed!

Can You Explain What Internet Is?

Wednesday, February 2nd, 2011

Here’s a video that can be enjoyed both by younger viewers and older viewers, but in very different ways.

This clip of The Today Show is apparently from January 1994. The hosts ponder over a new entity that seems to be cropping up all over the place, the strange and magical new Internet. If it’s not obvious, the person on the left is Katie Couric, the current anchor of The CBS Evening News.

The point of this is not to make fun of the hosts who, 17 years ago, could hardly have been expected to understand how ubiquitous the Internet would become in our lives. But the clip is intriguing as a frozen moment in time, recalling the days when you had to check the newspaper for movie listings and you had to buy stamps to mail a letter. Back then, the thought of someone like me writing something like this and having someone like you come here and read it would have been unthinkable.

Now if you’ll excuse me, I’m going outside to do a video chat on my mobile phone.

Salad Days

Friday, January 21st, 2011

The sixth-graders I’m working with are studying figurative language now, so we looked at figurative language in a scene from Antony and Cleopatra. They enjoyed the “salad days” metaphor, and the exchange where Cleopatra asks her servant Mardian about what it’s like to be a eunuch.

Cleo. Hast thou affections?
Mar. Yes, gracious madam.
Cleo. Indeed!
Mar. Not in deed, madam; for I can do nothing.

In other Shakespeare teaching news, I met with the eighth-graders who are doing As You Like It, and it looks like I will be working with them after all. And I’ve also hooked up with an enthusiastic seventh-grade class that has already read Hamlet, Much Ado about Nothing, and Romeo and Juliet. It looks like I have a few online classrooms to set up.

More to come!

I’m Big on Twitter

Wednesday, January 12th, 2011

I’ve gone back to tracking site hits, in preparation for bringing back the popular Googleplex feature on Sunday. That may or may not happen, since a lot of the searches I’m seeing are either very straightforward or repeats of searches I’ve used before. The repeats make me smile, though, because this time, the searchers are actually finding what they came looking for.

I’m noticing one big difference between the source links now and those of a year ago. Many of my hits are now coming in via Twitter, which is a relatively new development. I can’t see who links here on Twitter, so if you’ve been retweeting my posts, I thank you.

I’ve also been getting a lot more traffic in the new year. My Technorati authority is now 118 which ranks me at 36,240, while just two weeks ago, I had an authority of 108 and a rank of 56,666. I guess the increase in posting is paying off, though a lot of the impact seems to be coming from one post.

Sixty thousand, ho!

Fifty Apps for the iPad

Sunday, January 9th, 2011

Last year, I wrote that I didn’t need an iPad, because I had an iPhone and a Macbook Air. I still have them both, and they are still working out great. But my nephews got iPads for the holidays, and this is how I bond with them, so I had to get an iPad too. How’s that for a rationalization?

But now that I’ve bought one, I’m glad I did, because it’s adding value in ways I hadn’t anticipated. True, it is basically an iPod Touch with a larger screen, but that larger screen makes a big difference. There are a lot of things I can technically do with my iPhone, but usually don’t because the screen size is too small. And I’m finding it easier to do those things on the iPad.

So here are the top ten things you can do on an iPhone or iPod Touch that you can do better on an iPad:

1. Watch: I’ve been carrying around movies and TV shows on my iPhone for years, but I’ve watched more on the iPad in the last couple of months than I ever watched on the little screen. The Videos app (Included) is the very first app on my iPad. But I’ve also signed up for accounts with Netflix (Free app + $7.99/mo.) and Hulu Plus (Free app + $7.99/mo.) that let me stream video content from their impressive libraries. The combined monthly cost is far, far less than the Cable TV I’m canceling. And apps for YouTube (Included) and ABC Player (Free) help establish the iPad as a truly flexible video viewer you can take anywhere.

2. Connect: The power of social media has risen incredibly in the past year, and the App Store (Included) has kept pace. There are a variety of apps to help keep you connected, but I use Reeder ($4.99) as my Google Reader client, Friendly (Free) as my Facebook client, and Twitter (Free) as my client to access the Twitter account I finally broke down and created so that I could follow the national conversation where it seems to have gone. You can also consolidate the three, and much more, in one app called Flipboard (Free), which formats the content into a friendly magazine layout for casual browsing. There is also a WordPress app (Free), which allows me to blog on the go, and Yahoo! Messenger (Free) – actually an iPhone app – which lets users exchange text messages and participate in voice chat. And the iPad Mail interface (Included), designed for the larger screen, is much easier to use than its iPhone counterpart.

3. Read: The biggest surprise for me on the iPad is how much I love my Kindle app (Free), which lets me download books from Amazon and read them on the iPad. And these are real books that I actually want to read, not the limited eBook selection available through Apple. However, there are a lot of places online to get free books in ePub format, which can then be imported into your iTunes library and read on iBooks (Free), so you should definitely get it. I’m a fan of Offline Pages ($4.99), which allows you to save websites (from the iPad or from your home computer) and read them on the iPad, even after you’re no longer connected to the Internet. I also highly recommend the Shakespeare Pro app ($9.99) if Shakespeare’s your thing, and the Newspapers app ($2.99), which lets you access local newspapers from across the country on a daily basis.

4. Play: Any game you can play on the iPhone, you can play on the iPad, either in the original size, or expanded to fit the screen (sometimes with the expected loss of quality). But the expanded real estate has given developers something to code about, so there is a whole spate of new games and revamped versions of old games at the ready. Plants vs. Zombies is the absolute best game to ever grace the iPhone, and Plants vs. Zombies HD ($6.99) is even better on the iPad. Games like Cover Orange HD ($0.99) and Cut the Rope HD ($1.99), which combine tricky puzzles with engaging animations, demonstrate a new level of what is possible in portable gaming. Even the simple games, like Saving Seeds HD ($0.99) or Aces Traffic Pack HD ($2.99), really make you feel like you’re using a next generation device. I was able to play GT Racing: Motor Academy ($0.99) with my two nephews, each of us on our own iPads, racing each other on the same track. This was cool on a level they could not possibly appreciate.

5. View: I’d be remiss if I didn’t discuss how viewing photos is better on the larger screen, obvious as it may be. The iPad has a built-in Picture Frame feature, which lets the device function as a digital picture frame when it’s not otherwise in use. There are also apps that take advantage of the view, like Beautiful Planet HD ($0.99) that shows high-quality images from across the globe, and The Guardian Eyewitness (Free), which shows a different news photo every day. And The Elements ($13.99), the flagship app of the iPad, is everything it’s hyped to be: an interactive periodic table in which you can rotate high-quality 3D images of each of the elements. But it does take up almost 2GB of storage space, so don’t even bother with it if you’re only working with 16GB.

6. Work: The iPad is expensive to begin with, so it seems worth it to me to invest just a bit more in the iWork suite – Pages ($9.99), Numbers ($9.99), and Keynote ($9.99) – to add value to your device. I’ve also become fond of GoodReader ($2.99), which reads PDF files, and Teleprompt+ ($9.99), which allows you to load up text documents from your desktop and use the iPad as your own portable teleprompter. Try that with an iPhone.

7. Organize: I’ve actually not had a problem with the Calendar app on the iPhone, but the iPad’s Calendar interface (Included) makes it possible to see my whole month at a glance, which is a useful feature. As a MobileMe user, I like to use iDisk (Free app + $99/yr. for MobileMe) to coordinate between my desktop, laptop, iPhone, and iPad, but if you’re not a member, I’ve heard good things about Dropbox (Free app + Dropbox account). And I have to mention the Delivery Status app ($4.99), which lets you follow multiple packages from FedEx, UPS, etc. as they are tracked through the system.

8. Browse: The fact that the iPhone had a fully functioning web browser was a major breakthrough, but the iPad takes it a step further. It’s not only that the screen is larger, but also the fact that it allows you to view the full versions of your favorite websites, as opposed to the version optimized for mobile devices. Safari (Included) also syncs your bookmarks bar from its desktop counterpart (via MobileMe, I think), which I have found very convenient. It’s worth checking to see if the websites you frequent have their own apps as well. I recommend Google (Free), WolframAlpha ($1.99), and Articles ($4.99), which is a sharp-looking Wikipedia client.

9. Explore: Here’s how you know you are living in the future. Download GoSkyWatch Planetarium (Free) to your iPad. Then point it at the sky at night. It will display for you the same stars at which you are gazing, along with their names and even the constellations drawn in. Move the iPad around and the display will adjust. It’s also worth getting Solar Walk ($2.99), which gives you more freedom to move around the solar system and see what’s going on, including watching our own artificial satellites as they orbit around the Earth. The more expansive interface also breathes new life into old favorites such as Maps (Included) and Google Earth (Free).

10. Distract: So you’ve bought your iPad and now the kids want to play with it. What can you download to keep them out of your online banking app? The boys have their favorites, but Elena, who is now almost two, can work the icons along with the best of them, even knowing to hit the menu button when she’s bored with one app and wants to switch to another. Voting with her fingers, she recommends Sound Touch ($2.99), Art in Motion ($2.99), Tesla Toy ($1.99), and Drawing Pad ($0.99). Ian (age six) is really into roller coasters, so he enjoys games like New York 3D Rollercoaster Rush HD ($4.99) and Underground 3D Rollercoaster Rush HD ($4.99). But he really loves an app called Coaster Physics ($0.99), which lets him design his own roller coaster and then ride on it as he learns about kinetic and potential energy. He also likes to practice his Dolch sight words with All Sight Words ($0.99) and play Math Bingo ($0.99), while his older brother Jason (age eight) prefers MathBoard ($3.99) to hone his arithmetic skills. I highly recommend the BrainPOP Featured Movie (Free) and PBS’s SUPER WHY! ($3.99), two excellent educational apps by sources from whom we’d expect no less. And there are a whole host of apps that simulate baking different sugary confections, but Cupcakes! XL ($0.99) makes the best use of the iPad’s capabilities.

I certainly mean no disrespect to the iPhone. It’s still, hands down, the coolest thing I’ve ever owned, including the iPad. It has a phone and a camera and it fits in my pocket, so the new kid is really no threat. The iPhone is also better for listening to audio, recording voice memos, MusicID, and playing Doodle Jump or Catan. Most of the things I do with the iPad are things I wasn’t really doing with the iPhone anyway. So the iPad did add value after all.

And now all of my portable digital requirements really are met, and I therefore have no need for any new thing that should happen to be introduced by Apple or anyone else.

Do I?
