Lots of iPad commentary. Here's one typical review.
Farhad Manjoo says it's a perfect second computer. John Gruber likes the blazing-fast CPU.
I'm personally lukewarm, and I don't think it will replace my Kindle.
My favorite snarky blog comment was: "THE iPAD: 'Sounds like a feminine hygiene product.'"

Garry Kasparov: "The Chess Master and the Computer". One tidbit:
In 2005, the online chess-playing site Playchess.com hosted what it called a "freestyle" chess tournament in which anyone could compete in teams with other players or computers.(Via @bakadesuyo.)
...Lured by the substantial prize money, several groups of strong grandmasters working with several computers at the same time entered the competition. At first, the results seemed predictable. The teams of human plus machine dominated even the strongest computers.
The chess machine Hydra, which is a chess-specific supercomputer like Deep Blue, was no match for a strong human player using a relatively weak laptop. Human strategic guidance combined with the tactical acuity of a computer was overwhelming.
The surprise came at the conclusion of the event. The winner was revealed to be not a grandmaster with a state-of-the-art PC but a pair of amateur American chess players using three computers at the same time. Their skill at manipulating and "coaching" their computers to look very deeply into positions effectively counteracted the superior chess understanding of their grandmaster opponents and the greater computational power of other participants.
Weak human + machine + better process was superior to a strong computer alone and, more remarkably, superior to a strong human + machine + inferior process.

NYT article on bad passwords:
Back at the dawn of the Web, the most popular account password was "12345."
Today, it’s one digit longer but hardly safer: "123456."

"Despite carrying 90 percent of the planet's trade, nobody has mapped the network of links between the world's ports. Until now."
...[T]he maritime network shows some surprising differences from the network that flight paths make between airports. For example, on average, it takes just 2.5 jumps to move from one port to another on the maritime network compared to an average of 4.4 to move between one airport and another. The maximum shortest path between ports is 8 jumps while between airports it is 15 jumps. It looks to be decidedly easier to travel the world by ship than by plane, at least in some respects.
One oddity, however, is that the maritime network is decidedly asymmetric: more than half of all ports are linked in only one direction, meaning that cargo ships do not routinely make round trip journeys between ports.

"Do fire departments actually rescue cats from trees?"
The short answer is, "Yes, but they're not real excited about doing so". Plus:
The short answer is, "Yes, but they're not real excited about doing so". Plus:
...[I]t would be unwise to assume that the fire department is going to use advanced cat-rescue techniques.
Firefighters in Okinawa, Japan, earlier this year decided the best way to deal with a feline up a 60-foot tree was to grab a chain saw and lop off the section the cat was clinging to.
When a Tennessee woman's cat was stuck in a pine tree, firefighters gave her two options: they could blast it out with a hose or shake the tree until the cat fell out. When asked how option B was any different from the cat's just falling out on its own, one firefighter answered, "Neither is real different, ma'am. Just quicker."

"Up Close and Personal With the Pixel Qi Display":
Conventional LCD screens offer bright, glossy images but consume too much power. The images they display are also not visible in sunlight. It's one of the reasons electronic paper, a low-power black-and-white display that can be seen clearly outdoors during the day, has become a rage among e-book readers. Pixel Qi promises to bridge both worlds.The story includes detailed description and images of each mode. One important caveat:
Pixel Qi's 3Qi display operates in three modes: a full-color LCD transmissive mode; a low-power, sunlight-readable, reflective e-paper mode; and a transflective mode, which makes the LCD display visible in sunlight.
But unlike an E Ink display, even in the reflective mode, Pixel Qi's display burns power. E Ink displays don't consume power while you are reading the text on the screen. It just draws power when you turn the page.
Pixel Qi's display keeps refreshing at 60 Hz per second so it can't offer the week-long battery life that an E Ink-based reader does...

Science writer Gary Taubes on Richard Feynman and good science:
...In a commencement address that Richard Feynman gave at Caltech in the 1960s, he said that "the first principle [of science] is that you must not fool yourself -- and you are the easiest person to fool."The rest of the interview has some interesting discussion of food and nutrition as well.
So the simplest way to think about it is that good scientists are the ones who are most aware of this fact: how easy it is to be fooled by their data and to fool themselves. They're the ones who are most skeptical about their own work, not just the work of others. They're also aware that the only way not to be fooled is to work relentlessly to try to disprove your own pet theories, not try to confirm them.
Bad scientists do one experiment, get some interesting result, decide they've discovered something new, and then spend the rest of their lives trying to somehow prove that they did. Again, science doesn't work that way.
You have to put more faith in negative evidence than in positive; you have to put more effort into trying to refute your own beliefs and hypotheses, rather than trying to prove them. If you fail to refute them, then you can begin to take them seriously. And, yes, the inventors of cold fusion were bad scientists.

Taser's technology is creating the Proto-RoboCop:
...Police have so often been accused of using Tasers gratuitously that the firm started fitting them with digital cameras that recorded every firing. This "Taser-cam" got the firm's boffins thinking: why not equip police with cameras that can record entire incidents (not just the brief moment when a Taser is used) and even beam the recordings instantly back to the higher-ups at headquarters?
The result is a "tactical on-officer network computer" called AXON, which is being tested by several police forces in America. Recordings are uploaded to a restricted website, evidence.com, to be viewed by approved personnel. Mr Smith says that the creation of a sort of "secure YouTube of global law enforcement" could be beneficial both for the public, who would get more accountable police, and for officers on the beat, who could be vindicated more quickly if falsely accused of brutality.

Of course, we've been through a similar round of hype and speculation back in 2007 prior to Apple's official announcement of the iPhone.
Here are two reviews of the wrong guesses made about the iPhone prior to its release:
