Finding Lena, the Patron Saint of JPEGs

About six months later, a copy of the issue turned up at the University of Southern California’s Signal and Image Processing Institute, where Alexander Sawchuk and his team happened to be looking for a new photograph against which to test their latest compression algorithm—the math that would make unwieldy image files manageable. Lena’s glossy centerfold, with its complex mixture of colors and textures, was the perfect candidate. They tore off the top third of the spread, ran it through a set of analog-to-digital converters, and saved the resulting 512-line scan to their Hewlett-Packard 2100.

as she told me her life story, recalling her trips from America to Sweden, her marriages and jobs, the lives of her children and grandchildren, it became abundantly clear that the Playboy episode and its aftermath is a curious footnote, a part of her life that she has been largely excluded from, if only because no one thought to tell her very much about it.

Russia’s World Cup: a Putin own goal?
The thousands of visiting journalists (surely the largest foreign press contingent ever to spend a month in Russia) are likely to pump out the negative coverage that Russians call zloradstvo (evil-revelling). 

Doping wins Olympic medals but probably wouldn’t help much in skill-based, tactical football.

梁文道:從遊客到中國

任何「國情說」的預設,多半都離不開相對主義的討論,也就是說你不能外在地用一把尺子衡量所有國家、文化和社會的情形,必須從內部出發,看看那些國家、文化與社會自己對事情的想法以及評斷標準。

中國別有自己一套言行規範的話;我們在此所說的「中國」,究竟是哪一個「中國」呢?不論它是《詩經》裏的中國,還是《環球時報》的中國,它在這類說法當中都應該能承擔起一個價值原點的作用,有一套規範系統和邏輯,於是才可以用來支撐所有人我之別的說法,使得我在說「我和你不一樣,不要拿你那套來看我」這句話時理直氣壯。然而,當前各種「國情說」後頭真有這麼一個能夠說得上是價值源泉的「中國」嗎?

overlays - How can I distribute beamer overlayareas in handout mode across multiple frames? - TeX - LaTeX Stack Exchange
The <handout:O> syntax tells beamer to remove something from a slide in the handout version. It can also be used to tell beamer to put things on different slides in the handout version. Thus saying <handout:2> says "make sure that there is a second slide in the handout version and put this on it.".

Japan’s New Satellite Captures an Image of Earth Every 10 Minutes - The New York Times
A sense of perspective is unavoidable from 22,000 miles out. Looking down at Earth from that distance — almost three times farther than the diameter of the planet itself — allows a view of the globe as a massive organic system, pulsing with continuous movement.

Haze over Beijing : Image of the Day
The haze “disappears” in the infrared-enhanced image because tiny haze particles do not reflect longer-wavelength infrared light very well, making this type of image useful for distinguishing haze from clouds. The bank of clouds in the upper right corner shows up clearly in both pictures.
