This is the first of a couple ESA video’s I wanted to show; the next will probably be next Sunday. It’s been a crazy time lately, as I’m sure it’s been for everybody, hopefully thing will smooth out pretty soon.
Brodmann Blades Ping Pong Paddle Puts the Game In the Palm of Your Hand [Ping Pong]
Can you believe it? Ping Pong paddle gloves! The game, it has changed!
Now, granted, I haven't actually slipped my hand into one of these potentially revolutionary paddles, but the design alone had me salivating this morning and that has to mean something, right?
The $100 set includes the two paddles, four balls, terrycloth wristbands and a carrying case. The designer claims the more intimate palm-to-ball feel will result in a faster game with more spin and better control.
No idea if that's true or not, but I can guarantee using these paddles will result in a completely different game of table tennis. Question now is whether or not the International Table Tennis Federation takes notice. [Broadmann via Uncrate]
Changes in French Polynesia
I’m currently updating my guidebook Moon Tahiti for publication late next year. A surprising number of Papeete hotels have closed, and the declining dollar, rising prices, and the credit card blues have made packaged tourists from the United States an endangered species in French Polynesia.
pound # vs PSI (UOM)
Actually I can not differentiate between # pound unit of measurment and PSI unit. when we shall use the pound and when we shall use the PSI.
Suppose 3000 psi =?#(pound)
Thanks a lot for your help.
Wiring Diagrams for USB Cables?

Electronics May Still Be OK for U.S. and U.S.-to-U.K Air Travel [Rumor Smash]
When crazy stuff happens on airplanes, as it did on Christmas, you can rest assured security will tighten and terrifying electronics restrictions will fall into place. But in this latest case, our electronics? They may still be "safe."
I bring that up because there was apparently this nasty rumor going around that all electronics would soon be banned on all British Airways and Virgina Atlantic flights once these inevitable "new security measures" went live. And could you imagine? A trans-Atlantic flight without laptop movies, MP3 jams and podcasts, and positively no covert airplane mode smartphone adult content? Hell in an aluminum tube, says I.
But it's apparently not true, for now. Both airways said electronics are still GO, even as some previouslt reported "unpredictable" security measures go into place over the next few days.
American carriers, like Continental, United and AA, have also not changed their security measures in the wake of the attempted Xmas Day terrorist attack—yet—so getting home from your relatives this week could still be moderately bearable, as far as air travel goes anyway. [Pocket Lint]
Happy Holidays to You, Dear Weird Dude and Your Sex Fembot [Robots]
Remember Aiko, the fembot created by amateur inventor Le Trung? Well, apparently she and his boyfriend/creator spent Christmas with his family, and he even got her presents. He claims that she's exactly like a real woman. Seriously, Le? Let's review:
"Aiko can recognise faces and says hello to anyone she has met."
OK. Sounds good enough.
"She helps me pick what to have for dinner and knows what drinks I like."
Hmmhmm.
"Like a real female she will react to being touched in certain ways."
Right.
"If you grab or squeeze too hard she will try to slap you."
Correct.
"She has all senses except for smell."
Fine. That can be convenient at times.
"[Walking] is the most difficult thing for any inventor to do. The problem is finding a way for Aiko to walk that looks human-like without impacting on any of her other abilities. I have spent the last six months taking her apart and trying out lots of different systems, but I haven't been able to get it right yet."
Ooooooook. So she doesn't walk and you can take her apart to rebuild her.
"But Aiko is always helpful and never complains. She is the perfect woman to have around at Christmas."
Come on, Le, you had me until you said that. That's not very realistic. But then again, whatever rocks your world, dude. If you are happy, Aiko is happy, and we are all happy. Just don't have another heart attack while working on her, like you had two years ago.
I wish the New Year brings you both happiness and no tight white jackets. [Daily Mail]
Safe voltage in the hydrocarbon industries……
Dear friends,what is the safe voltage limit that can be exposed in the hydrocarbon plants.....can we use battery operated ordinary device/meters in field ?which standard represents that?Thank you,....
Making a longbow
As noted earlier, I found a piece of IPE. It was suggested that I make a longbow. Since the IPE has lots of wiggles, I think it might not do for a selfbow but would need to go into a laminated one. Now the problem...what to laminate it with. I have no ash and no white oak or hickory. What other wood
Montana Senator Max Baucus slobbering Drunk on the Senate floor
Slurring, Stumbling, and clearly Snockered
From the Editor: This video is making the rounds of the Rightosphere, ironically brought to us from TPM at the Leftosphere. We here at Libertarian Republican have given a great deal of coverage to the Max Baucus Sex Scandal, involving the appointment of his Mistress to a top position at Eric Holder's Attorney General's office. In fact, you could say we've been leading the media/blogosphere on the story.
With that background in mind, we believe it prudent to bring to you this Video. Perhaps all the pressure has gotten to the good Senator from Montana? Or maybe, he just forgot to sleep it off on his Senate office couch after the Dem Caucus Christmas Party?
Note: At exactly 3:25 Baucus gets especially beligerant, and sluring.

Anniversary of a cosmic blast | Bad Astronomy
Five years ago today — on December 27, 2004 — the Earth was attacked by a cosmic blast.
The scale of this onslaught is nearly impossible to exaggerate. The flood of gamma and X-rays that washed over the Earth was detected by several satellites designed to observe the high-energy skies. RHESSI, which observes the Sun, saw this blast. INTEGRAL, used to look for gamma rays from monster black holes, saw this blast. The newly-launched Swift satellite, built to detect gamma-ray bursts from across the Universe, not only saw this blast, but its detectors were completely saturated by the assault of energy… even though Swift wasn’t pointed anywhere near the direction of the burst! In other words, this flood of photons saturated Swift even though they had to pass through the walls of the satellite itself first!
It gets worse. This enormous wave of fierce energy was so powerful it actually partially ionized the Earth’s upper atmosphere, and it made the Earth’s magnetic field ring like a bell. Several satellites were actually blinded by the event.
So what was this thing? What could do this kind of damage?
Astronomers discovered quickly just what this was, though when they figured it out they could scarcely believe it. On that day, half a decade ago, the wrath of the magnetar SGR 1806-20 was visited upon the Earth.
Magnetars are neutron stars, the incredibly dense remnants of a supernovae explosions. They can have masses up to twice that of the Sun, but are so compact they may be less than 20 kilometers (12 miles) across. A single cubic centimeter of neutron star material would have a mass of 1014 grams: 100 million tons. That’s very roughly the combined mass of every single car on the United States, squeezed down into the size of a sugar cube. The surface gravity of a neutron star is therefore unimaginably strong, tens or even hundreds of billion times that of the Earth.
What makes a neutron star a magnetar is its magnetic field: it may be a quadrillion (1015) times stronger than that of the Earth! That makes the magnetic field of a magnetar as big a player as the gravity. In a magnetar, the magnetic field and the crust of the star are coupled together so strongly that a change in one affects the other drastically. What happened that fateful day on SGR 1806-20 was most likely a star quake, a crack in the crust. This shook the magnetic field of the star violently, and caused an eruption of energy.
The sheer amount energy generated is difficult to comprehend. Although the crust probably shifted by only a centimeter, the incredible density and gravity made that a violent event well beyond anything we mere humans have experienced. The quake itself would have registered as 32 on the Richter scale — mind you, the largest earthquake ever recorded was about 9 on that scale, and it’s a logarithmic scale. The blast of energy surged away from the magnetar, out into the galaxy. In just 200 milliseconds — a fifth of a second — the eruption gave off as much energy as the Sun does in a quarter of a million years.
A fireball of matter erupted out of the star at nearly a third the speed of light, and the energy from the explosion moved — of course — at the speed of light itself. This hellish wave of energy expanded, eventually sweeping over the Earth and causing all the events described above.
Oh, and did I mention this magnetar is 50,000 light years away? No? That’s 500 quadrillion kilometers (300 quadrillion miles) away, about halfway across the freaking Milky Way galaxy itself!
And yet, even at that mind-crushing distance, it fried satellites and physically affected the Earth. It was so bright some satellites actually saw it reflected off the surface of the Moon! I’ll note that a supernova, the explosion of an entire star, has a hard time producing any physical effect on the Earth if it’s farther away than, say, 100 light years. Even a gamma-ray burst — an event so horrific it makes the hair on the back of my neck stand up just thinking about it — can only do any damage if it’s closer than 8000 light years or so. GRBs may not even be possible in our galaxy (they were common when the Universe was young, but not so much any more), which means that, for my money, magnetars may be the most dangerous beasties in the galaxy (though still unlikely to really put the hurt on us; see below).
Here’s what Swift detected at the moment of the burst:
As Swift scientist David Palmer describes:
This is the light curve that [Swift's Burst Alert Telescope] saw, showing how many gamma rays it counted in each sixteenth of a second during six minutes of observation. I didn’t draw the main spike because it was 10,000 times as bright as the tail emission, and you would need a monitor a thousand feet tall to look at it.
The blast was so strong Swift saturated, counting 2.5 million photons per second slamming into it, well off the top of that graph (and the actual blast was far brighter yet, as other satellites were able to determine).
See the pulsations in the plot? After the initial burst, which lasted only a fraction of a second, pulses of energy were seen from the magnetar for minutes afterward. The pulses occurred every 7.56 seconds, and that’s understood to be the rotation period of the neutron star. The crack in the crust got infernally hot, and we saw a pulse of light from it every time it spun into view. This same pulsing was seen by other satellites as well.
The damage from the explosion was actually rather minimal here on Earth. But that’s because SGR 1806-20 is 50,000 light years away. Had it been one-tenth that distance, the effects would have been 100 times stronger. We’d have lost satellites at least, and it would have caused billions of dollars in damage in NASA hardware alone. Of the dozen or so known magnetars, none is that close (though a couple are about 7000 light years away). Magnetars aren’t easy to hide, but it’s possible there are some within 5000 light years. It’s unlikely, though, and I’m not personally all that concerned.
I do have one thing to add: when this event occurred, I got an email from someone convinced that the magnetar was responsible for the earthquake in Indonesia that created the devastating tsunami that killed more than 250,000 people. However, there is one small problem with that idea. Well, two problems, really, the first being there’s no physical way it could have triggered an earthquake! But a worse problem is that the earthquake occurred on December 26th at 00:58 UT, and the burst from the magnetar was at December 27 at 21:30:26 UT, about 1.5 days later. Oops.
But why let facts get in the way of a good pseudoscientific theory?
The tantrum from SGR 1806-20 is one of the best studied events of its kind, and is certainly the most powerful ever detected in the modern era. Astronomers will be studying the magnetar, and others like it, very carefully to see what can be learned from them. If you want to read more, then I suggest the NASA page about the event, as well as the Sky and Telescope magazine page on it, too.
And if another blast like that one comes from SGR 1806, or any other magnetar, don’t worry: I’ll report it right here. Unless it fries my computer. Or just my brain, reading about it.

The Vile History of Gift Cards and How They Came to Destroy Christmas [Gift Cards]
Gift cards have ruined Christmas. An utterly depressing fact: They're the most popular present in the United States. Did you know Blockbuster is responsible for the modern gift card?
The Big Money's history of gift cards is a fascinating timeline of how they spread like a virus, infecting every gift-giving tradition we hold dear: Neiman Marcus actually was the first to sell gift cards, in 1994, but because the retailer didn't quite understand their potential, the cards were kept out of sight and sold only as a novelty item. Blockbuster was the first to display them, starting in 1995, which was the true beginning of the gift card revolution.
Starbucks was the next major innovator, in 2001, with gift cards that worked more than once, so you'd have to keep going back. (Today, one out of seven purchases is made with a gift card at Starbucks in the US.) Which brings us to the present, with gimmick cards like Best Buy's tiny speaker or Target's little camera, or purely electronic ones, like for Steam and Amazon.
Did your Christmas feel more empty and hollow this year? Did you give or receive a gift card? Bingo. Gift cards are the most cynical of all presents, lower than cash. They lock the receiver into a particular store or service, while relieving the giver of any responsibility, thought or feeling. If someone gives you a gift card, they don't care about you. In fact, they're trying to trick you, and make you think that they do, because they took the time to select a store to purchase your piece of plastic from. That is a lie—the effort went into the ruse, not your gift.
Of course, stores love gift cards, a pure token that holds no value after it's purchased, except that which the merchant dictates. Odds are, when somebody comes in to spend a gift card, they'll use to buy something more expensive. Even if the gift card is never used, the store still keeps the money—and most unused gift cards lose value over time, withering with the seasons. It's an $87 billion con by the retail industry, and Americans, obsessed with convenience, have eaten it up.
If you're thinking about buying somebody a gift card because you can't be bothered to pick out a real present, don't. Give them cash. Sure, you might feel like an asshole—well, you kind of are—but I promise you, the person receiving the wad will like it a whole lot more than any gift card. Cash can be spent, anytime, anywhere, and it won't expire in a year (unless the economy completely collapses, then we've got bigger problems than declining gift standards).
Update: I forgot to make the important exception for independent and local specialty stores, like record shops. Gift cards are okay in that case (small businesses need money, speciality stores require some consideration).
Here's a question that's quickly becoming a dilemma, though. What's a better (worse?) gift, cash or digital media? [The Big Money]

Is Your Kindle Spying On You? (Yes.) [Ebooks]
If you don't want other people to know what you read, you probably shouldn't own an ereader. And you really shouldn't get a constantly connected Kindle or Nook, at least according to the EFF's eye-opening guide to ebook privacy.
The Kindle and Nook are tied to Amazon and Barnes & Noble's respective bookstores, meaning every purchase and every book search is recorded. Amazon's license agreement for the Kindle, for instance, notes that the Kindle's software "will provide Amazon with data about your Device and its interaction with the Service...and information related to the content on your Device and your use of it (such as automatic bookmarking of the last page read and content deletions from the Device)."
The Nook is obviously capable of phoning home in a similar manner, but it's unknown whether or not it does, at least for now. With Google Books, it's clear that what you're actually reading is logged, down to the specific page.
On the other hand, since Sony's Reader lacks 3G for a constant connection and isn't as tightly integrated with their ebook store, there's less opportunity for data collection, particularly if you stick w/ sideloaded books. Better still, says the EFF is the open-source FBReader. But you can't download books from anywhere in 3 seconds over 3G, and the experience isn't as nice.
It's the classic tradeoff: Less privacy for more convenience and a better experience, or greater privacy for a bigger hassle. What side are you on? [EFF]
