Uh Oh

How secure is Internet security? A team of researchers recently set out to crack the security of about 6.6 million sites around the Internet that use a supposedly “unbreakable” cryptosystem. The good news is that they succeeded only .2% of the time. The bad — and rather shocking — news — is that .2% of 6.6 million is almost 13,000. That’s 13,000 sites with effectively no security. The interesting part is what went wrong. It’s a gaping security hole that I’d never stopped to consider, but is obvious once it’s pointed out.

We’ve Come a Long Way, Baby

I haven’t been able to find the exact quote, but unless my memory is playing tricks, Martin Gardner once posed the question “What modern artifact would most astonish Aristotle?”, and concluded that the answer was a Texas Instruments programmable calculator that could be taught to execute simple series of instructions. That was, roughly, 1975.

Here is what my iPhone does: It listens to the radio and tells me the name of the artist, song and album. It scans bar codes and tells me where to get the same item cheaper. It gives me step by step directions to anyplace I want to go. It points me to the nearest public bathroom. It recommends restaurants, based on cuisine, price, and proximity. It plays any music I want it to play, and it recommends new music based on what it’s learned about my preferences. It shows me a photograph of the entire earth and lets me slowly (or quickly) zoom in on my (or your) front porch. It takes pictures. It takes videos. It lets me edit those pictures and videos. It photographs 360 degree panoramas. It plays movies. It plays TV shows. It displays pretty much any book, newspaper or magazine I want to read. It reminds me where I parked my car. It lets me draw rough sketches of diagrams with my fingers and makes them look professional. It allows me to accept credit cards. It takes dictation. It checks the stock market or the weather with the push of a button. It reminds me of my appointments. It lets me browse the Web. It shows me my email. It locates and summons nearby taxicabs. It turns itself into a carpenter’s level. It turns itself into a flashlight. It makes phone calls. It makes video calls. And, oh yes — it has a calculator.

Now who would have been more astonished? Aristotle confronted with Martin Gardner’s calculator, or the Martin Gardner of 1975 confronted with my iPhone? I’m going to say it’s a close call.

Video Arcade

So after futzing around with one clunky inadequate free product after another, I finally plunked down an amazingly reasonable $59 for the AVS4you software suite, which unlike everything else I’ve tried, actually works, and works well. This has allowed me, pretty much painlessly, to re-create much better versions of some of the videos that I’ve posted here in the past. (Better, that is, in terms of quality, and in terms of format, and in terms of file size.)

There is still, of course, the inevitable tradeoff between better quality on the one hand and less bandwidth on the other. I think I’ve found the sweet point, but am still experimenting.

The current batch of experiments is here. If these download too slowly, or are frustrating to watch for other reasons (other than, perhaps, the content, which is another matter) I’d like to know about it. If they work for you, I’ll be glad to know that too.

PS: It seems crystal clear that these work much better (in the sense of not stalling) in .flv format than as, say, .mp4, even when the flv files are much bigger, and I have the vague sense that everybody in the world except me understands exactly why. Do educate me.
