Every once in a while we say goodbye to a technology that has been replaced by a demonstrably superior successor, yet we still hold onto a bit of nostagia for the old way. One of those about to go extinct is Polariod instant film. Even though I hadn't used it for years, I was sad to hear on NPR's All Things Considered that the film is going out of production.

Digital photography is our efficient, truly instantaneous modern standard, but there was something magical about a Polaroid picture. Even if the final prints were not as good as standard film, Polaroid had its own mystique.

The whole process had a satisfying, ritualized nature to it. You composed the photo, clicked the shutter and heard that distinctive whirr. The seemingly blank film shot out. You'd fight to see who got to grab it, shake it (for no real reason--it just seemed like it needed to be shaken like a mercury thermometer), and watch as the image teasingly developed before your eyes. The film was expensive; about a dollar a shot if I remember correctly. You'd have to carefully parcel out the ten shots in a pack to make it last through a whole party.

A few artists had clung to the medium for their work. They are mourning the end of the Polaroid era, saying that for some applications, nothing compares to the look they could get from this film.

For me, it is strange to see something that I remember as cutting-edge technology as a kid become so thoroughly obsolete. So while digital photography may be superior in almost every way, let's say one final "click, whirr" farewell to Polariod.

Video games have been around long enough now that we can see a new trend developing--gamer parents. These parents have been playing games themselves for years, and look forward to playing games with their kids as a way to spend time together as a family.

The new "Ask GamerDad" column on the video game guide side What They Play brings this perspective to video game reviews and advice. Whether or not you are a gamer parent yourself, this point of view can be another useful resource when considering games for your kids.

In this week's column, "Gamer Dad" Andrew Bub talks about video games as fitness tools, drawing on his own experience of losing 30 pounds over four years by playing Dance Dance Revolution every day. This activity more than just "play" for Bub, as he relied on this weight loss to help him survive a heart attack at age 36.

The fitness options are expanding with family-oriented games such as Wii Sports and Wii Fit, which has been a big hit in Japan will be released in the United States in mid-May. I believe that a virtual sport should never replace 'real-world' family interactions. Even so, parents who are not major gamers themselves may embrace some of these new activities as a wholesome, and possibly healthy, opportunity to play with their kids.

The law doesn't seem to have caught up with the evolving concept of online defamation yet, so internet service providers and websites are generally not responsible for the content that their users post. There are many valid reasons for that legal approach, but the website JuicyCampus.com stretches the credibility of this concept. The website's sole reason for existence is to serve as a portal for anonymous gossip, spreading rumor, sexual defamation, homophobia, anti-Semitism, and racism at colleges across the country.

In the era of cyberbullying tragedies, it's depressing to think that a site like this passes for entertainment.

The good news is that a backlash has emerged from students themselves, who are beginning to realize that just because you can say something, doesn't mean you should. I would love to see consumer pressure strike a blow for decency and common sense, without having to invoke legal action or government regulation. It will be interesting to see whether the company's bubble pops on its own.

JuicyCampus.com was started by Duke University grad Matt Ivester. He gives overprivileged college students everywhere a bad name. I don't know anything about his personal background, but it is sad to think of a spot at Duke going to someone who couldn't come up with better use for his prestigious education.

"...Nobody is in the room. The professor is just another open browser window, 1 of 10."

Immersion in online technology and media has fundamentally changed the way our minds work, the way we gather information and split our attention. It may be harder than ever for educators to avoid coming across like the monotonous economics teacher in Ferris Bueller's Day Off. I taught high school 10 years ago, and in many ways I am thankful that I was teaching in the era before networked laptops.

I was a talented teacher, but let's face it, when you are trying to convince 16-year-olds that they really are interested in learning chemistry at 8:30 in the morning, it helps to have a captive audience.

Now teachers face new pressures: competing for their students' attention inside the classroom, and presenting material in a way that resembles the variety of mass media that teens consume on average more than 40 hours a week.

What's more worrisome than a public MySpace page? A page that the user only thinks is private. I was just alerted to several stories by Kevin Poulsen of Wired News that publicize recent security breaches on MySpace.

Poulsen reported on January 17 about a MySpace Bug that leaks "private" teen photos to voyeurs. He wrote, "A backdoor in MySpace's architecture allows anyone who's interested to see the photographs of some users with private profiles--including those under 16--despite assurances from MySpace that those pictures can only be seen by people on a user's friends list. Info about the backdoor has been circulating on message boards for months."

These message boards include self-described groups of "pedos" who hacked into underage-girls' private MySpace profiles. According to Poulsen, one poster reported successfully pilfering photos from a randomly chosen 14-year-old girl, "It worked and I was shown her pictures. Now lets see some naked sluts."

On January 18, Poulsen updated the story to say that the next day, MySpace quietly fixed that back-door bug, without publicly acknowledging the problem, even though users' profiles had been vulnerable for months.

When PBS's Frontline reported on "Growing Up Online" this week, it called the gulf between kids who grew up with technology and their parents "the greatest generation gap since rock 'n' roll." That's a bitter pill to swallow for adults in their '30s and '40s who have been involved in computers for 20-plus years, but I have to say I agree with their assessment. Maybe we kicked it old school with Pong and the Atari 2600. Or we had a Commodore 64 or a Macintosh with a whopping 512K of memory. We may have even written code since we were teens ourselves, but that's nothing compared to growing up with ubiquitous access to cell phones, media, and social networking.

Producer Caitlin McNally describes this shift in thinking that exists even between her, as a twentysomething, and the teens she interviewed:

Despite the research we did, I don't think I was prepared when we started talking to kids for the extent to which the Internet and other electronic communication has permeated all aspects of being a teenager. Almost every kid expressed the utter importance of being connected with friends all the time and how unthinkable a life without that connection would be. I think a lot of kids were bemused by our list of questions about 'life online,' because they don't sit around thinking about the Internet in their lives. It's just there, always, another tool for them to use or place for them to go.

Wonderful things can happen when you are open to unexpected possibilities. That's one lesson I take from the story that starts with a software program called Singing Coach. Carlo Franzblau had wanted to learn to sing since he was an off-key teenager with musical theater aspirations. In 2000 he developed Singing Coach, software with an American-Idol-in-training vibe. Users sing karaoke-style into a microphone and the software tells them whether their pitch is too high, too low, or in tune.

While performing quality-control tests on Singing Coach, Franzblau received some unexpected feedback: one of the first testers was a middle school student named Ashleigh who happened to be a struggling reader, and her mother reported that the singing software was improving her daughter's reading.

Franzblau pursued this unexpected finding with gusto. He teamed up with literacy professor Dr. Susan Homan at the University of South Florida to conduct a research study to see if Ashleigh's finding represented a genuine effect. Dr. Homan found that struggling readers benefited greatly from the program, raising their test scores by more than a whole grade level after nine weeks of training with the singing program, which has been redeveloped specifically as a reading intervention called "Tune In to Reading." The kids who used Tune In To Reading sustained their gain, continuing to make progress six months later even when they were not using the program.

There's a contradiction in our approach to kids and electronic media: we want parents to supervise their kids and guide their appropriate use of games and media, and at the same time we talk about kids being "digital natives" who understand the gaming world much better than many parents do.

Let's face it, kids can spend hours talking to each other about the latest gadget or video game, and it is a challenge for parents to catch up. Most video game reviews discuss a game from the player's point of view without giving parents the details they need to judge whether a particular game is appropriate for their child. (I frequently encounter the same problem with movie reviews for kids' films. I am usually not that concerned about how "good" a kids' movie is, but I want to know the details behind a movie's PG-13 rating. Yet that information is rarely provided.)

A new Web site called WhatTheyPlay.com fills in this information gap. The site launched in November and already features a well-populated catalog of game reviews. Now parents can get the details beyond ESRB ratings, with objective reviews and user comments, to decide for themselves whether they want to bring a game home for their family. ... Read more

Apple's announcement of its new ultrathin laptop couldn't have come at a better time. After lugging around a huge pack at CES last week and nearly breaking my back, my top wish coming out of the convention was for a truly portable laptop, and I have always used Macs.

I have been trying to be less consumeristic lately (going to CES didn't help that either!) but I have to say that the MacBook Air inspired an instantaneous, primal reflex of consumer lust: Me want that.

Apple's new ad showing the MacBook air emerging from a manila envelope is truly brilliant. Ten seconds into the video, I was totally sold on the concept.

I currently use a 15-inch MacBook Pro, which is quite nice so it's a bit hard to justify the concept of upgrading, but we'll see how much rationalization I can muster up over the next few months. I used to carry the lowest-end, smallest MacBook and my expensively-won conclusion is that smaller is better in almost every situation. I know that MacBook Pro is objectively superior to MacBook in many ways, but I have always wondered whether I am the only person who feels that the metal casing is so cold that it's detracts from my tactile experience. Probably something I'll have to learn to live with from here on out.

I will resist my Pavlovian urge to preorder a MacBook Air. I'll do my best to wait until the first wave crests and we see how the stand-in-line-all-night faithful respond. I have learned that there is no sense buying any device until you've tried out the keyboard in person. And I'd like to see if any quick modifications will be coming in the foreseeable future. I embrace the wireless nature of the MacBook Air but I do question my ability to live without an Ethernet port. As one CNET reader commented earlier, most offices may be wireless-enabled, but on the road, which is the whole point of an ultraportable, a surprising number of hotels still require an Ethernet hookup to get online.

After the iPhone, Apple had quite a challenge to come up with the next big thing. Looks like they've pushed the (manila) envelope again this time.
