The State of the Union is NOT Strong
Here are some encapsulating gifs of the charade that goes on in Washington. Career politicians making grand plans with your money. What an embarrassment. The state of the union is NOT strong, the state of the Union is a state of emergency, and bankruptcy. These guys will be out of there in a few years, leaving behind a fine mess that neither party seems to have a clue, or the fortitude to resolve.

FDA: Aleve May Be Safer on Heart Than Rival Drugs
FDA: Aleve May Be Safer on Heart Than Rival Drugs
WASHINGTON January 28, 2014 (AP)
By MATTHEW PERRONE AP Health Writer
Federal health officials say the pain reliever in Aleve may be safer on the heart than other popular anti-inflammatory drugs taken by millions of Americans.
A Food and Drug Administration review posted online Tuesday said naproxen — the key ingredient in Aleve and dozens of other generic pain pills — may have a lower risk of heart attack and stroke than rival medications like ibuprofen, sold as Advil and Motrin. FDA staffers recommend relabeling naproxen to emphasize its safety.
The safety review was prompted by a huge analysis published last year that looked at 350,000 patients taking various pain relievers. The findings suggest naproxen does not carry the same heart risks as other medications in the class known as nonsteroidal anti-inflammatory drugs, or NSAIDs.
The agency released its memo ahead of a public meeting next month where outside experts will discuss the new data and whether naproxen should be relabeled. The agency is not required to follow the group's advice, though it often does.
If ultimately implemented, the labeling changes could reshape the multibillion-dollar market for drugs used to treat headaches, muscle pain and arthritis.
The change could make Aleve and other naproxen drugs the first choice for patients with a higher risk for heart problems, according to Ira Loss, a pharmaceutical analyst with Washington Analysis. But he added that all NSAIDs will continue to carry warnings about internal bleeding and ulceration, a serious side effect that is blamed for more than 200,000 hospital visits every year.
The FDA meeting is the latest chapter in an ongoing safety review of NSAIDs that stretches back to 2004, when Merck & Co Inc. pulled its blockbuster pain reliever Vioxx off the market due to links to heart attack and stroke. Vioxx was part of a subset of newer NSAIDs designed to be easier on the stomach. But in the wake of the Vioxx recall, the FDA beefed up warnings about heart safety risks on all drugs in the class, including Motrin, Advil, Aleve and Celebrex. Pfizer's Celebrex is the only drug from the same class as Vioxx that remains on the market.
Current labeling warns that taking NSAIDs long-term can increase the risk of heart attack and stroke. Patients and doctors are advised to take the drugs for the shortest time period possible.
But FDA staffers said in Tuesday's memo that labeling should be changed "to reflect the more favorable cardiovascular risk profile of naproxen."
Bayer spokesman Chris Loder said in a statement that naproxen's safety and efficacy is "based on clinical trials, observational studies and clinical and real world use for more than 38 years." The German-based conglomerate is one of a half-dozen pharmaceutical manufacturers presenting at the FDA meeting, scheduled for Feb. 10 and 11.
The FDA also disclosed Tuesday that it is considering halting a long-term study comparing the safety of naproxen, ibuprofen and Celebrex, the prescription painkiller from Pfizer.
Given that recent data show a lower rate of heart attack and stroke for naproxen, FDA staffers say patients in the trial are being "exposed to an undue risk."
Launched in 2006 by Pfizer, which makes both Celebrex and Advil, the PRECISION study is expected to be completed by late 2015. The company said in a statement that "current evidence does not support" changes to the labeling of its drugs.
Celebrex was New York-based Pfizer's fourth-best-selling drug last year, with sales of $2.92 billion.

How Sony Is Ushering In a Golden Age of Photography
How Sony Is Ushering In a Golden Age of Photography
David Pogue
Jan 23, 2014

Next time you’re at a pro sports game, car race or rock concert, take a look at the cameras the professional photographers are using. Guess what? They’re not taking pictures with their phones.
They’re not using cameras like these, either:
No, they’re probably using cameras like this:
I’ve always assumed that there’s a reason for deliberately hauling six pounds of equipment around one’s neck. Probably because you need a big camera to accommodate a big sensor, the “film” in a digital camera.
It’s very simple: Big sensor = better photos.
A big sensor can absorb more light. It makes possible sharp photos with better color in low light. Less digital “noise” (random speckles). And with the right settings, a big sensor also makes possible a large aperture, which gives you that delicious, professional-looking blurry background.
In short, the single most important statistic about a camera is not the number of megapixels (which actually means very little to picture quality). It’s sensor size.
Until last year, you could make this equation, too: Big sensor = big camera. I mean, look at the relative sizes of these cameras and their sensors (I threw the iPhone camera sensor size in there for your amusement):
What the world has always wanted, of course, is a small camera with a big sensor.
I’ve always assumed that that’s impossible. Year after year, the camera companies cranked out new models that basically stuck to the same formula: Big sensor = big camera = big price. We all assumed that there was some reason camera makers couldn’t stuff bigger sensors into smaller cameras — like, say, the laws of physics.
A few years back, though, Panasonic and Olympus struck a huge blow for small cameras with big sensors when they introduced a format for mirrorless cameras called Micro Four Thirds. (“Mirrorless” cameras can be smaller than real SLRs, because they don’t contain the usual system of mirrors and prisms to bring the light from the lens to your eye. Instead, the viewfinder has a little screen.)
But for the last couple of years, Sony has been taking the small camera/big sensor concept to thrilling new levels. The challenge is not physics, Sony says, but cost and difficulty. Nobody puts big sensors into small cameras because the price would be too high for consumers and because it would involve redesigning everything: body, lenses, processor and so on.
These days, most cameras fall into one of three categories shown above: pocket size, consumer SLR, and professional SLR. Here’s a look at what Sony’s been doing in each category.
Pocket size
Let’s start with the classic pocket camera — 4 inches wide, built-in flash, no eyepiece viewfinder.
Shown here on the left: a representative pocket camera. Price: $250. Sensor: tiny. On the right, Sony’s best, the RX-100 II: nearly three times the price, but a sensor nearly quadruple the size. (In this article, everything is pictured at scale — cameras and sensors — for your eyeballing convenience.)
There are other reasons the RX100 II is more expensive, of course; it is, in essence, a miniaturized professional camera. It has a hot shoe on top (an attachment for accessories), a screen that tilts up or down, an incredibly fast f/1.8 lens (meaning amazing low-light photos and the ability to blur the background), wireless sharing to your phone, a control ring around the lens, a programmable Function button, manual controls over everything, 10-frames-per-second burst mode, Sweep Panorama (just swing the camera around you and it builds a 360-degree panorama automatically), and better components all around.
But, really, that huge sensor is the key. I maintain that the RX100 II is the best pocket camera ever made, and so far, nobody who’s tried it has disagreed. Here are a few sample shots:
That last one: handheld, no flash, dead of night. That’s impressive.
I also maintain that $700 for a compact is borderline price gouging. Sony knows that the world will pile onto this thing like piranhas, and it intends to milk every penny.
Speaking of which: You can save $150 by buying the previous year’s model, the RX100. It offers the same size sensor but lacks the tilting screen and the WiFi and isn’t quite as good in low light. But it’s only $550.
Superzoom fixed-lens
There’s another oddball but popular camera category worth mentioning in here: the superzoom fixed-lens camera. These cameras have one permanently attached zoom lens. The Nikon Coolpix L820, for example, can zoom 30x. Sony’s own HX300 zooms to 50x.
That’s a big deal when you’re trying to photograph sports action from the stands, or musical-theater action in a school auditorium.
The marketing of these cameras, however, has always infuriated me. It’s great that they zoom a lot — but the zooming comes at a terrible cost. These cameras have the same microscopic sensors as the cheap $250 pocket cameras.
Worse, the more you zoom in, the smaller the maximum aperture (the size of the shutter opening). Once you’re zoomed in fully, you have a tiny aperture indeed, which means you have a greater likelihood of blurry shots. (Why? Because the shutter has to stay open longer to admit more light. And during that time, any motion of your little athlete or tenor — or of your hand holding the camera — creates a blur.)
Superzoom cameras are generally lousy at focusing when they’re fully zoomed, too.
Sony’s freakishly unusual RX10 solves both problems. It’s that rare superzoom with an 8.3x, constant-aperture zoom. It’s f/2.8 the whole zooming way, 24 to 200 mm. (You can control the zooming either with a ring or with a lever; it’s slowish both ways, though.)
Sony calls the RX10 a “premium” superzoom; it’s $1,300 — again, crazy steep — and absolutely loaded. It has the same 1-inch sensor size as the RX100. It can shoot 10 frames a second (yet another reason it’s a great sports camera). It has a magnesium alloy body, weather-resistant so you can shoot in the rain. An aperture ring around the lens. A tilting screen. Crazy great video with full manual and auto modes. Microphone and headphone jacks, three control rings, a flash that pops up high enough to clear the lens completely. Even a built-in neutral-density filter — a useful feature when you want to cut down the amount of light, especially useful when you’re shooting video and you want that blurry-background look.
“There’s nothing the RX10 can do that a larger SLR couldn’t do with two lenses,” a Sony manager explained to me. “But you wouldn’t get 10-frames-a-second burst mode, autofocusing all the way.” And you couldn’t take telemacro shots (15 inches to your subject) without yet another lens.
Sony also cheerfully points out that if you bought an f/2.8 70–200 mm lens for an SLR, you’d pay more than $2,000 just for the lens.
Finally, of course, there’s the biggest RX10 advantage of all: having to carry only a single piece of gear that does almost everything.
Consumer SLRs
Let’s move on now to SLRs — the big, black cameras with interchangeable lenses. If you want to stay under $1,000, the biggest sensor you can get is what’s known as APS-C. That’s the sensor size found in, for example, Canon’s popular Rebel line. (The name comes from the Advanced Photo System film specification. That kind of film is no longer with us, but its dimensions live on.)
Here, Sony’s ability to pack a big sensor into a small camera does not require a price penalty. In fact, Sony’s least expensive SLR actually costs less than Nikon’s. This illustration shows the relative sizes of these two cameras:
And check out how much thinner the Sony is; it’s less than half as thick. In fact, overall, the Sony camera’s body occupies only 26 percent as much volume as the Nikon’s.
If I wanted to buy an inexpensive SLR, you’d better believe I’d get one of Sony’s NEX cameras. Why on earth would I want a camera that’s four times as big, 85 percent heavier, and $50 more expensive — if I could get the same photos from a smaller, lighter, less expensive camera?
Pro SLRs
But now we have to talk about full-frame sensors. That’s the Holy Grail. That’s a huge sensor, the size of one 35 mm film frame of old.
The bigger a sensor is, the more expensive it is to make. That’s why the pros pay so much for their cameras — like the awe-inspiring Canon 5D Mark III ($3,500 without the lens) or the Nikon D800e ($3,000 without the lens). These cameras are incredible. Their sensors are so big, they can see more in the dark than you can.
“It’s cool that Sony has shrunk the cameras around 1-inch and APS-C sensors,” the photographic world used to sigh. “But too bad it can’t pack a full-frame sensor into something that size, so I don’t have the bulk of a microwave oven hanging around my neck.”
Well, don’t look now, but Sony’s finally done it.
The Sony A7 is the world’s smallest, lightest interchangeable-lens full-frame camera. It’s the first one that you can shove into a coat pocket.
And, amazingly enough, it doesn’t cost more than the other full-framers on the market. In fact, it’s among the least expensive: $1,700 for the body alone, or $2,000 with a 2.5x zoom lens (28–70 mm, f/3.5–5.6). No wonder it’s rocking the photographic world (and earning its place as Popular Photography’s Camera of the Year).
I have much more to say about the Sony A7; you can read the nitty-gritty, and see more sample pix, in my review here.
Sony ascending
In the high-end camera market right now, Nikon and Canon are the Big Two camera companies. Sony trails at number 3.
Now, listen: I’m aware that camera choice is a religion, like iPhone vs. Android. Canon, Nikon, and the other companies make some truly sensational equipment. What I’m about to say is in no way intended to slight them, or you if you prefer them.
But here’s the thing: When a company is on top, it has an overwhelming incentive to preserve the status quo, to keep doing what it’s always been doing. When you’re the underdog, on the other hand, you have every incentive to shake things up, to take risks (*cough* Yahoo *cough*).
“We don’t believe that camera sales are slowing down just because people are using their phones for photography now,” a Sony rep told me. “We think it’s because camera makers aren’t doing interesting things anymore.”
Well, Sony has certainly been doing interesting things. A 1-inch sensor in a pocket camera? Never been done. A premium superzoom? Nobody else is doing that. A full-frame sensor in a coat-pocketable body? Unheard of.
These are great ideas, and they’re arriving in great cameras. Yes, Sony may be No. 3 — but it tries harder.

Correction: An earlier version of this story referred to the Sony RX10 as the world’s first fixed-aperture superzoom camera. In fact, Panasonic has offered fixed-aperture superzooms, although with much smaller sensors.

How Carl Bass, the CEO of Autodesk, is shaping the maker movement—from his garage
How Carl Bass, the CEO of Autodesk, is shaping the maker movement—from his garage.

Carl Bass
Brad Wenner
When you first meet him, Carl Bass comes off like any other weekend carpenter. Dressed in a worn T-shirt and jeans, he shakes hands with a wooden grip and has a big, brassy laugh. His workshop is a warren of lumber and hammers and idle projects. A half-built chair sits here. A sculpted Styrofoam head there.
But Carl Bass is no ordinary carpenter. He’s the CEO of Autodesk, a $10-billion company that makes AutoCAD, the standard software used by engineers to digitally design such products as cars, airplanes, and skyscrapers. And his maker space is no ordinary garage. First, it’s huge. His wood shop alone occupies 20,000 square feet—and he’s got a comparably sized metal shop down the street. Second, it’s sophisticated. 3-D printers sit among the band saws and planers. And then there’s his CNC router.
“This is my coolest thing,” Bass says, stepping to the monitor that controls it. He’s a big guy, tall and thick, but he looks small next to this machine. The Thermwood 90’s five-axis head can move anywhere within a 5’ x 10’ x 4’ space and can carve pretty much anything—a perfect orb, a model of the space shuttle or Michelangelo’s David—out of materials like plastic and plywood. The machine is incredibly complicated. It usually comes with its own instructor. “I don’t think anyone else has one for themselves,” Bass says.
Bass isn’t boasting. He has poured at least as much money into his workshop as other CEOs pour into vintage wine collections or boats, but his hobby isn’t about impressing anybody else. It’s just for him. He still spends every Saturday morning from 6 to 11 beavering away on various projects in pleasant isolation. And yet, his weekend work is having a profound effect on the maker movement.
A few years ago, Bass recognized that two powerful forces were poised to intersect: the rise of online sharing and the return to analog building in maker spaces. Up until that point, Autodesk stuck primarily to the virtual realm by developing increasingly refined CAD software. Bass saw that Autodesk could fill a crucial niche by helping everyday people bridge the gulf between digital design and physical manufacture.
The Maker King
Brad Wenner
The company’s first consumer product was an experiment. A team in Toronto developed a dramatically simplified modeling program, formatted it for use on mobile devices, and put it online as a free app, called Sketchbook. Within 50 days, Sketchbook had a million downloads. So the company created more products, and then a whole consumer group focused on design, personal manufacture, and home decoration. In three years, Autodesk had more than 100 million registered users across its various consumer products. Compare that with the company’s 12 million professional users, which it took more than three decades to accrue.
The range of applications people found for the new products was tremendous. Louise Leakey, the famed Kenyan paleontologist, recently used 123D Catch, a web-based app that stitches snapshots into a 3-D image, to model her skull collection so others could view it online. With 123D Make, a product that allows people to modify 3-D models, fans then carved the CAD skulls into pieces that could be printed and reassembled as a puzzle. In Florida, the owners of a female duckling named Buttercup used Autodesk software to get the animal back on its feet after an amputation to correct a birth defect. They made a model of Buttercup’s good foot and printed it. After the surgery, they attached the prosthetic, so she could waddle and paddle like any of her companions.
Autodesk’s new role as a company that enables makers suits Bass just fine. Before he started his own software firm, which was acquired by Autodesk in 1993, he put himself through college by working as a carpenter, building houses on a Sioux reservation and boats in Maine and Seattle. He’s found it easy to infuse Autodesk with that same hands-on enthusiasm. “The company is filled with engineers and people who like to make stuff, so it wasn’t like I was pushing a rock up a hill,” he says. Bass recently provided his employees with their own version of his personal workshops: a 27,000-square-foot maker space at the edge of Pier 9 in downtown San Francisco. The facility includes a wood shop, a metal shop, an electronics shop, a 3-D–printing lab, a tailor shop, replete with mannequins, and a test kitchen (on the premise that cooking is a gateway drug for makers). When the facility opened with a ribbon cutting last September, Bass, true to form, took a reciprocating saw to a steel bow instead of scissors. Shortly afterward, a group of Autodesk engineers designed, printed, and assembled a 13-foot-tall blinking Trojan horse that they pulled up to Market Street in San Francisco—just because they could.
Bass recognized that two powerful forces were poised to intersect: the rise of online sharing and the return to analog building in maker spaces.
Futurists have long predicted a day when people can manufacture most of what they need in the comfort of their own homes. It would be easy to see the Autodesk shop and Bass’s personal maker spaces as a step in that direction—larger and more expensive, but a step nonetheless. But Bass doesn’t give in to such optimism so easily. Because he’s going first into the age of personal manufacture, he is intimately acquainted with the barriers that stand in the way.
“We’re so close to real personal manufacturing, and yet we’re so far,” he says. It’s not as if something designed in Google Sketchup can just be handed to the router, he explains. “Right now, you have to convert all these file formats from one to the next, and you lose fidelity with every step. If I can’t do it with my resources, connections, and equipment, who can?”
The only solution, he says, is persistence and personal experience. “At Autodesk, anytime we find issues with a product we’re using, we go about problem solving, trying to make them better. In the end, we’re just making things easier for people, so more of them can access the maker movement.”
CNC Router
“My Thermwood 90 is an 18,000-pound router that will carve anything. Lately, I’ve been using it to make big carved tables.” — Carl Bass
Brad Wenner
In that way, Bass’s workshop serves a dual purpose. It’s a sanctuary, sure, a place where he can build anything from swooping chairs that appear cut from a single piece of wood to intricate 3-D–printed mesh sculptures. But it’s also a test bed. And every one of his creations carries a backstory—a series of challenges and lessons that lead to a final success. “I might not be able to understand what an Autodesk customer is up against, but I sure can sympathize,” he says. Bass makes stuff because that’s what he loves, but in doing so, he’s also creating a better experience for his customers and, in a way, for everyone.
He shows me around a bit more. A row of bats he made with his kids, lathed perfectly and sanded to a high gloss, hangs from a rack on the wall. An antique sander sits nearby. Finally, he flicks off the lights, and darkness advances across the space the way it does in factories and airplane hangars. Then he turns to me.
“One thing I wish I had,” he says. “I wish I had more space.”

What's in Carl's 20,000-square-foot-personal workshop?
Sander
“I bought this gigantic drum and disk sander at Industrial Light & Magic, the special effects shop that did Star Wars. It’s from 1940 and can sand anything.”
Lathe
“It’s fun and easy to use. I typically use it to make baseball bats and chair legs and poles.”
Chisels
“I found a set of Stanley chisels on Ebay. They were used when I got them, but I sharpened them up, and now I use them on everything.”
Hand planes
“I built them myself 35 years ago. It’s nice to have built a tool more than three decades ago and still use it.”
