Master Chao: Chinese virtuouso flat-pattern designer

Andrew "bunnie" Huang -- the guy who broke the Xbox and founded Chumby -- has a great blog post today about Master Chao, a middle-aged Chinese man who has helped design thousands of everyday products that fill your gadget bag and home. Master Chao's gift is in creating flat patterns for sewing into three dimensional shapes, something that is insanely hard to model well on computers. I heard bunnie give a talk on Chinese manufacturing process last June, and his lyrical description of Master Chao's virtuoso performance has stayed with me.
It turns out there are still things where Craft, and I use it with a capital "C" here, matters-it's where CAD tools haven't brought about the ability to simulate out our mistakes before we build them. The creation of a flat pattern for textile goods is a good example of a process that requires a Craftsman. A flat pattern is the set of 2-D shapes used to guide the cutting of fabrics. These 2-D shapes are cut, folded and sewn into a complex 3-D shape. Mapping the projection of an arbitrary 3-D shape onto a 2-D surface with minimal waste area between the pieces is hard enough; the fact that the material stretches and distorts, sometimes in an anisotropic fashion, and the fact that sewing requires ample tolerances for good yields makes it a difficult problem to automate. On the chumby, we add another level of complexity, because we sew a piece of leather onto a soft plastic frame. As you sew the leather on, the frame will distort slightly and stretch the leather out, creating a sewing bias dependent upon the direction and rate of sewing. This force is captured in the seams and contributes to the final shape of the device. I challenge someone to make a computer simulation tool that can accurately capture those forces and predict how a device will look at the end of the day.

Yet, somehow, Master Chao's proficiency in the art of pattern making enables him to very quickly, and in very few iterations, create and tweak a pattern that compensates for all of this. It's astounding how clever and how insightful the results can be. And really, the point of this particular post is to introduce you to a person whose old-world skills -- absent computers, all done with cardboard, scissors and pencils -- has likely played a role in the production of something that you have used or benefited from in the course of your life.

Beautiful colored kaytdids

200709111411 Asahi Shimbun reports that a woman in Osaka discovered these pretty katydids in a field.
Osaka Museum of Natural History entomologist Itaru Kanazawa identifies them as the larvae of Euconocephalus thunbergi (”kubikirigisu” in Japanese), a close relative of the katydid. While he says it is normal for these insects to change between green and brown to match their surroundings, pink and white are considered abnormal.

TNS: Ad Spending Slips Two Quarters in a Row

Gains for Cable TV, Consumer Mags, Outdoor and Web

NEW YORK (AdAge.com) -- U.S. ad spending in the first half of this year slipped to $72.59 billion, a 0.3% decline from the first half of 2006, as the second quarter repeated the falloff of the first.
The top 10 advertisers' collective outlay fell 2.2% in the first half as five of them made significant cuts.
The top 10 advertisers' collective outlay fell 2.2% in the first half as five of them made significant cuts.

If the drop seems slight, remember that media sellers' costs are rising fast. Even more unsettling, this is the first time since 2001 that media ad spending has fallen for two quarters in a row, according to TNS Media Intelligence, which produced today's numbers. More challenges ahead "While the protracted downturn in automotive spending has been a prime contributor, the overall results reflect weakness across a wide range of industries and advertisers," said Steven Fredericks, president-CEO of TNS. "Given the uncertainties about near-term economic growth and consumer spending, we expect core ad spending will continue to face challenges during the second half of the year." It's true that the first quarter of 2006 was blessed by the Winter Olympics ad bonanza, but it would have been soft even without the Olympic effect. And the second quarter declined without any particularly tough comparison from 2006. The only media to gain were cable TV, which was up 2.8%; consumer magazines, up 6.9%; Sunday magazines, up 4.3%; Spanish language magazines, up 13.1%; outdoor, up 3.6%; and, of course, the internet, up 17.7%. That internet figure doesn't include keyword search or video advertising -- TNS doesn't track those. TV feels pain The brunt of the budget cuts hit network TV, which was down 3.6%; spot TV, down 5.4%; business-to-business magazines, down 7.2%; local magazines, down 4.2%; local newspapers, down 5.7%; national papers, down 6.4%; Spanish language papers, down 4.4%; local radio, down 1.5%; national spot radio, down 5.3%; and network radio, down 4.4%. The top 10 advertisers' collective outlay fell 2.2% in the first half as five of them made significant cuts. Spending fell 12.5% at AT&T; 25.1% at General Motors; 7.9% at Time Warner; 9.1% at Johnson & Johnson; and 2.6% at Walt Disney. Fortunately for the media business, the other half increased their budgets. The biggest advertiser, Procter & Gamble, raised ad spending 1.8% to reach $1.61 billion. Spending also rose at Verizon Communications, which was up 8.8%; Ford Motor, up 2.7%; Sprint Nextel, up 13.5%; and National Amusements, up an impressive 56.5%. By category, declines registered in telecom, which was down 6.3%; nondomestic auto, down 6.1%; domestic auto, down 10.8%; and travel and tourism, down 1.2%. The biggest category of the half, financial services, expanded spending 3.5%. Local services and amusements spending increased 2.1%. Miscellaneous retail (excluding department stores, food stores and home furnishing and appliance stores) grew 0.2%. Direct-response advertising rose at the greatest rate, 11.3%. Personal-care products grew 6.7%. And restaurants expanded 0.8%.

Adobe: Photoshop Goes Online and Free

psx_screenshot.jpgWhile it's still a teaser at the moment, John Nack (senior product manager for Photoshop) has confirmed the development of Photoshop Express. It's a free online photo editor that's not meant to replace Adobe's current offerings, but "make Adobe imaging technology immediately accessible to large numbers of people." And from the screenshot here you can tell it's not even a dumbed- down Photoshop, but an entirely new product (that reminds us of something from the new iLIfe).

The announcement follows Adobe's implementation of Premiere Express, their online video editor, and it signifies a fairly progressive market plan by Adobe. In a content creation culture where every teen is a video editor, the democratization of powerful multimedia tools online allows Adobe to reach out to this new generation without abandoning their industry professional bread and butter. And it makes us want to remind kids that we once edited a movie on a VCR (after walking 30 miles barefoot in the snow, aiming our kite for lightning to capture the electricity to do our work).

Canon firmware hack unlocks features on DIGIC II-based cameras

This hack has been floating around the internets for a little while now, but it looks like Canon users have just recently begun to catch on to its charms, and its fairly significant benefits. For those not up to speed, the so-called CHDK firmware hack promises to unlock several advanced features of Canon's DIGIC II processor, not the least of which is support for RAW shooting, something normally reserved for higher-end cameras. Other hidden features including a live histogram, a "Zebra mode," a DOF calculator, and even a calendar, text reader, and games, among other things. While the hack should work with any DIGIC II-based camera "in theory," there's apparently only eight cameras that are officially supported, including the A610, A620, A630, A640, A700, A710, S2 IS, and the S3 IS. Of course, as with any firmware hack, you should proceed at your own risk, but those daring enough can find all the information they need by hitting up the read link below. [Via Gadget Lab]
