I chose to travel with my newish 13 inch MacBook Pro instead of my newish Asus Eee PC. It's just a one-day trip to LA and I figured I wouldn't be needing the 8-hour battery, but there is a fundamental difference between the two computers. With the MacBook I'm always looking for a power outlet. With the Asus, you know you're going to make it all the way without a charge, so you can relax about power. Apple may think they have the battery issue licked, but they don't. And the fact that you can't carry a spare battery for this computer is a real step backward.

Very thorough build notes from Viacheslav Slavinsky, who built a plotter from scratch, then souped it up by adding a 300 mW laser in place of the pen. I was interested to note that while 300 mW isn't a lot of laser power, apparently it can cut through slightly more than a centimeter of "high density foam." I'd be curious how it fares against EPS and/or XPS. [via Hack a Day]

Got an old radio from the '20s, and want to bring it back to life? Well, the quickest way is probably be to remove all those dusty components and use the cabinet to hide a new stereo. That's not what radio hacker Greg Charvat had in mind for his, though. Instead, he restored the original radio circuitry, and even hooked it up to his iPod.
Along the way, he ran into all sorts of neat discoveries, and many potential pitfalls. It turns out that electronics have changed quite a bit in the past 80 years, and even the most basic components such as resistors and capacitors can be unrecognizable. Another issue is that the cloth and rubber used for insulation on the wiring will have dried out, making it necessary to handle everything extremely carefully. One nice thing about equipment of this vintage, however, is that it was usually designed to be repaired, so chances are good that a schematic is available.
To give you an idea of the issues one should expect to encounter when attempting this, here is the overview he gives in a presentation about the project:
As usual for high-voltage projects, and especially for high-voltage projects involving unknown vintage equipment, don't attempt this unless you have the proper training, because the electronics inside are most certainly deadly. Don't give up though, just make sure you learn enough to know what you are doing!

This is a kea. Isn't he cute? Happy, little green parrot...tra la la.
This little parrot will mess your s**t up. If you are a sheep. Image courtesy Flickr user PhillipC, via CC.
Happy, little green parrot who calmly burrows through the still-living flesh of sheep and dines upon their kidney fat while they lay bleating in terror. No, really. You can see a video here. Watch Clip 4, starting about two minutes in.
And now, the context....
Kea are incredibly intelligent mountain parrots, native to New Zealand. Most of the time, they eat the sort of things you'd expect parrots to eat: Berries, nectar, insects. But that food is in short supply during the winter months, and kea--while they do migrate from mountain tops down into the warmer valleys--don't fly away to summer climes. Plus, the encroachment of ranches, farms and cities drove off a lot of their traditional food sources over the last few centuries. So, in winter, the birds are sometimes forced to get creative about their meals. And that's where the sheep come in.
Unsurprisingly, ranchers are not pleased. There've been legends of sheep-killing parrots since the early days of European colonization in New Zealand. Kea were killed off in droves and even had a bounty on their heads for a while. Ironically, though, a lot of people claimed the legends were just that, right up until kea were caught on film, dining on sheep in 1993---seven years after conservationists won a hard-fought battle to protect the birds against the threat of hunting and extermination. Today, they're still a protected species, but their numbers are also still on the decline---thanks to habitat loss, falling prey to other animals, and sometimes deadly human attempts to keep the inquisitive (and frequently destructive birds) away from cars and bicycles.
The keas' story is a complicated tale of what happens when humans tamper with nature...and nature tampers back. Great stuff. Thanks to Nathan Torkington for the video link!

This is a $300 "professional" video grip for the iPhone 3Gs. However, I can't imagine any "professional" choosing to shoot video with their iPhone, much less have a KIT to do it.Inexplicably expensive iPhone accessory (video stabilizer)"Zacuto has the first serious solution for shooting video with the iPhone 3Gs."

"Right, okay, the one thing that does skew our ratings is that older people buy more music. They steal less music.... So like, you know, a Bruce Springsteen or a Madonna might overperform on the album sales chart relative to some more subjective measure of their popularity. But as far as like who's stealing what... I mean, what use is that?"And that, right there, is why Billboard has become so obsolete. It's lead by people who think that file sharing is "stealing" and that it's meaningless in figuring out where the money is in music. It ignores the studies that have shown that people who download also end up buying more music. It ignores the studies that show people who download are more likely to attend a show or buy merchandise (things that Billboard doesn't appear to think matter at all in the industry). It's as if Billboard wanted to judge the popularity of the transportation industry by judging how many buggy whips are sold. Yes, as automobiles became more popular, buggy whip sales declined. Sucks to be you if you're focused just on measuring buggy ship sales, but the problem is that you're measuring the wrong thing.
How does complexity happen? From the unpredictable behaviour of financial markets to the rise of life from inert matter, Leo Kadananoff, physicist and applied mathematician at the University of Chicago, finds the most engaging questions deal with the rise of complex systems. Kadanoff worries that particle physicists and cosmologists are missing an important trick if they only focus on the very small and the very large. "We still don't know how ordinary window glass works and keeps it shape," says Kadanoff. "The investigation of familiar things is just as important in the search for understanding." Life itself, he says, will only be truly understood by decoding how simple constituents with simple interactions can lead to complex phenomena.Seven questions that keep physicists up at night
What is reality really? The material world may, at some level, lie beyond comprehension, but Anton Zeilinger, professor of physics at the University of Vienna, is profoundly hopeful that physicists have merely scratched the surface of something much bigger. Zeilinger specialises in quantum experiments that demonstrate the apparent influence of observers in the shaping of reality. "Maybe the real breakthrough will come when we start to realise the connections between reality, knowledge and our actions," he says. The concept is mind-bending, but it is well established in practice. Zeilinger and others have shown that particles that are widely separated can somehow have quantum states that are linked, so that observing one affects the outcome of the other. No one has yet fathomed how the universe seems to know when it is being watched.

Over on the Facebook blog, head of security Max Kelly has just explained what to do to memorialize the profile of someone who has passed away:
We understand how difficult it can be for people to be reminded of those who are no longer with them, which is why it's important when someone passes away that their friends or family contact Facebook to request that a profile be memorialized. ...When an account is memorialized, we also set privacy so that only confirmed friends can see the profile or locate it in search. We try to protect the deceased's privacy by removing sensitive information such as contact information and status updates. Memorializing an account also prevents anyone from logging into it in the future, while still enabling friends and family to leave posts on the profile Wall in remembrance. If you have a friend or a family member whose profile should be memorialized, please contact us, so their memory can properly live on among their friends on Facebook.Memories of friends departed endure on Facebook via CNet

"The fact that music I helped create was used in crimes against humanity sickens me," (former Rage Against The Machine guitarist Tom) Morello said in a statement. "We need to end torture and close Guantanamo now....""Torture songs spur a protest most vocal"
A White House spokesman said music is no longer used as an instrument of torture, part of a shift in policy on interrogations that Obama made on his second full day in office.
"Sound at a certain level creates sensory overload and breaks down subjectivity and can [bring about] a regression to infantile behavior," said Suzanne G. Cusick, a music professor at New York University who has studied, lectured about and written extensively on the use of music as torture in the current wars. "Its effectiveness depends on the constancy of the sound, not the qualities of the music." Played at a certain volume, she said, "it simply prevents people from thinking."

In early September, David Reed sent this interesting message to the IRTF's "end-to-end" email list. List members include some world experts on Internet protocols. During the next couple of days, there were over 40 messages in related threads. While some of these experts were over-thinking the problem, if you are patient enough to read through the many messages, what emerges is clear. At least in the case David measured (from a hotel room in Chicago, while he had 5 bars of signal strength, using an AT&T Mercury 3G data modem in his laptop), the terrible throughput and extreme delays he experienced appear to result from overly large buffers in the routers &/or switches in AT&T's core network. Note: if you don't want to read all the list messages the short summary is: >8 second pings times!

Boing Boing reader Ken Ward caught Friday's Rachel Maddow Show segment, in which I joined Ms. Maddow for a discussion around John McCain's "Internet Freedom Act." McCain, who once described himself as technologically "illiterate" and is the single largest senate recipient of telecom lobby money, is now campaigning against the net neutrality fundamentals recently reaffirmed by FCC actions.
Our reader suggests another reason McCain is dead-wrong: "At the risk of sounding like a dinosaur, I have to point out that McCain's positions is, in fact, a danger to National Security." Ken's email to Boing Boing, after the jump. Your thoughts welcomed in the comments.
Ken writes:
Interesting exchange between you and Rachel Maddow regarding McCain's position on Net Neutrality. At the risk of sounding like a dinosaur, I have to point out that McCain's positions is, in fact, a danger to National Security. Let's remember that the Internet grew out of DARPA, the Defense Advanced Research Projects Agency, which itself grew out of ARPA, the Advanced Research Projects Agency (an Eisenhower baby), both of which were government-funded efforts to ensure that government and military computer networks could survive and maintain in contact in the event of a nuclear or environmental disaster.Boing Boing readers: your thoughts on this argument? Tell us in the comments.The National Security function of what is today known as the Internet has already been largely degraded by the privatization of the Internet backbone, and McCain's bill only further puts at risk National Security by allowing private enterprise to determine the "importance" of Internet packets. As I see it, the best and only way to understand McCain's bill is as a betrayal of National Security interests.
Best regards,
Ken

Susannah Breslin pointed me to Marilyn Minter 's latest video months ago, but I didn't get around to blogging 'til now. Green Pink Caviar is described as
A lush and sensual voyeuristic hallucination. Filmed with macro lenses, the video was inspired by a photo shoot where Minter directed her models to lick brightly colored candies while she shot photos from underneath a glass plate. The models' tongues mixed the colorful sugar with saliva, slurping and pushing color across the glass surface to simulate painting.More: greenpinkcaviar.com, some viewer reactions, Los Angeles Times interview with the artist, NBC LA, and apparently there's some controversy over the billboard installation in Hollywood.

The daughter of reader Amie Miller wants to know, "Do turtles have eyelashes?"
Short answer: No.
Eyelashes are, in general, kind of a mammal thing--what with being made out of hair and all. Besides their usefulness in pseudo-comic flirting and as a habitat for freakishly awesome mites (as well as their importance as an advertising revenue stream for Hulu), eyelashes also work as a trap, catching bits of dust and other scrapey-ouchy particles before they can reach our eyeballs.
But as we behold the motes eyelashes protect us from, we have to consider the beams that surely must be getting into the eyes of creatures unfortunate enough to be lash-less.* Poor, little turtle.
Or not. Non-mammals have their own way around this problem. They protect their eyeballs with a nictitating membrane--basically a third eyelid that slides in horizontally from the side. Besides having a great name, the nictitating membrane also has some pretty cool features eyelashes can't claim. For instance, nictitating membranes are translucent. Turtles can close their third eyelid completely, but still see. It's a skill that's particularly useful when you spend a lot of time swimming around with your head mostly below the waterline--kind of like having built-in goggles. Amphibians and reptiles have nictitating membranes. So do birds, who use them to protect and moisten the eye during flight much the same way that turtles use them in the water.
But mammals aren't wholly without nictitating membranes. In fact, you have the vestigial remnants of one. Called the plica semilunaris, it's that little lump on the inside of your eye, next to your nose. In animals that still use them, nictitating membranes are associated with glands that secrete eye-moistening goo. So it's no coincidence that the "sleepies" you pick out of your eye in the morning come from the same area as your plica semilunaris.
For humans, nictitating membrane may be a thing of the past, but other mammals still get some use out of it. Harbor seals, which spend plenty of time underwater, have functioning nictitating membranes. So do camels, who use the third eyelid for added protection during desert sand storms. Aardvarks, awesomely, actually use the thing to keep termites from biting their eyes while they (the aardvarks) are trying to eat them (the termites).
Cats and dogs have nictitating membranes that are somewhere in-between. Their membranes still exist--and still work--but our pets can't control them the way turtles and other creatures can. Instead, nictitating membranes only show up when the cat or dog is sick, or otherwise messed up in the head. Case in point, I last saw my cat, Red's, nictitating membranes on a drive from Alabama to Minnesota, for which the vet had prescribed a slightly higher-than-necessary dose of kitty Valium.
*Please see the Book of Matthew, chapter 7, verse 3. It's an awkward joke, yes. But give me a break, here. I've got four years of Baptist high school-worth of Bible verses memorized and I'm not just gonna let that go to waste.
When I was guesting on BoingBoing last spring, my friends' son Will wanted to know whether cockroaches had a penis. I enjoyed tracking down the surprisingly complicated answer, so I thought I'd keep the theme going now that I'm on full-time. I'm hoping to answer a Science Question from a Toddler once a month, though that depends on me getting questions. Which brings me to this request: If a smallish child you know has a science question--on any topic--send it to me. I'll do my best to answer.
The child does not have to be your own. Questions do not have to be cute or "Kids Say the Darndest Things-ish" in any way. They do not even have to be current. (Baby boomers, got a query that's been nagging at you since 1975? I don't care if the toddler is now in their 30s, send the question!) All I'm looking for are things you can't answer off the top of your head and don't feel like researching yourself. Easy stuff!

Most intriguing is the sum paid by Apple to settle an SPT suit brought over the iPhone in the Eastern District of Texas in 2008: $865,000. Without any motions being filed after the intial complaint or any substantive discovery, a bit more than 30 percent of that amount, $271,817, went to Niro Scavone, which also billed $46,568 in expenses. Nearly $40,000 went to someone identified as "Ward"--most likely Johnny Ward Jr., who served as local counsel to SPT in the case. Of what was left, almost $109,000 went to SP Technologies, then owned by investor Courtney Sherrer, and $311,400 went to Boesen.There's a lot more in Mullin's post. Not sure how much is worth commenting on, but given that such patent holders and patent hoarding companies tend to be incredibly secretive about all of this stuff, it's still an interesting peak behind the curtain.
Also noteworthy: a full 10 percent of Apple's payout, $86,500, is marked as going to "LG"--an apparent reference to LG Electronics, which, according to the Boesen receipt, paid $834,964.01 to settle a separate SPT suit in 2006. Why would LG be getting a cut of the settlement in a suit to which it was not a party? And was Apple aware that a piece of that settlement might wind up with one of its competitors? Representatives from Apple and LG did not immediately respond to requests for comment.

Steve Sasson, the man credited with inventing the first digital camera, has been awarded an honorary doctorate from the University of Rochester for his work. Sasson developed the first prototype, with a resolution of 0.01 megapixels, in 1975 while working at Kodak and received a patent for it in 1978. Although the diagrams included in the original patent won't look too familiar, its description of 'a solidstate light responsive device' for image capture is instantly recognizable.

Bob Thompson, our resident Make: Science Room lab geek, answered a question in the comments for the "Setting Up a Home Science Laboratory Part II - Gearing Up" topic, about buying digital scales. I thought it was worth posting here for the benefit of others.
Cynthia asked:
What would you recommend in the way of a digital scale for intermediate/high school science? I was thinking of purchasing one that was a 1000 g capacity with a 0.1 sensitivity. Could this both serve chemistry and physics, etc.?
Bob's reply:
Good question. The two big trade-offs in buying a balance are capacity and resolution. Ideally, we'd all like an inexpensive balance with 0.0001 gram resolution, but unfortunately, there aren't any such animals.

The balance I chose two or three years ago for my own home lab is the desktop MyWeigh iBalance 201, which has 200 gram capacity and 0.01 gram (centigram) resolution. That's still a current model, and is available in Maker Shed and elsewhere. However, it's also a $100+ balance.

If you're looking for something a bit less pricey, Maker Shed also carries a portable $33 electronic balance (on sale through 10/31 for $29) that has the same 200 gram capacity and 0.01 gram resolution. I have one of those as well, and it's a very nice little scale. I suspect it probably isn't quite as durable as the i201, but OTOH, it's less than a third the price. (It's also useful around the house. My wife just used it yesterday to see if she needed to put a second stamp on an envelope.)
My take on this is that 200 g is sufficient capacity. Almost any experiment you do that would use the 1000 g capacity of the balance you're considering can be scaled down to work within the 200 g capacity of these balances. OTOH, having 0.01 g resolution instead of 0.1 g resolution is very nice, particularly for chemistry.
It'll also save you money on chemicals. For example, if you need to make up a solution to a particular accuracy, being able to weigh out (say) 7.87 g of the chemical and making up 100 mL of solution is cheaper than having to weigh out 78.7 g of the chemical and make up 1,000 mL of the solution.
