11 Feb 2016: Watching hundreds of sheep get herded around the grassland from above is a pretty magnificent view. It’s like watching a real life hourglass somehow spill out. There’s a slight chokehold at the opening point of the fence but the sheep all move so fast that it’s actually pretty impressive. Nothing can move from one place to the next as fast.

Written in both pen and pencil, the astronauts scribbled down flight plans, a series of numbers and notations from mission control and a calendar. Each day of the Apollo 11 mission is crossed out except for the final day, July 24, when Columbia returned to earth.

  • Columbia is where the three astronauts lived during most of the eight-day mission in July 1969. It's the only part of the spacecraft that returned to earth, and it's been at the Smithsonian since 1970 and at the National Air and Space Museum in Washington, D.C., since it opened in 1976
  • Workers at the Air and Space Museum have been scanning the spacecraft for a 3-D digitization project. Once inside, they found writing on the interior walls of the command module. "They can be seen by the human eye if you were to go into the Command Module, which of course no one can normally do. We were able to take these photos because we allowed one of our conservators to go in, very strategically and carefully," Alison Mitchell of the Air and Space Museum told NPR in an email.

11 Feb 2016: In the standard restaurant scenario, you think about a nice steak, so you order it. You see it coming and then eat it, and have your fantasy fulfilled. Everyone is on the same page, expecting the steak to taste like what we have come to associate with steak. But wily chefs, from the age of Nero to Noma, harness the power of surprise pleasures, not fulfilling expectations but reversing them in a positive way. Make delicious what looks or sounds unpleasant, or downright inedible.

  • Edible dirt is a thing. It is what it sounds like: food disguised as dirt. Pioneered and developed by Michel Bras in the late ’70s and eventually served at his eponymous restaurant, the original dirt was a mix of dried black olives, crumbed brioche, and tomato powder. In 1992, he famously served a plate of vegetarian crudités in what looked like a slice of vegetable garden, inspiring chefs for decades to come. René Redzepi, Daniel Patterson, James Syhabout, David Kinch, and Jeremy Fox have all played dirty. What each chef’s “dirt” is made of varies: it could be coffee and cardamom, hazelnuts soaked in beet juice, roasted parsnip, or chicory and dehydrated potato.

     

  • The fun, if you’re into this sort of thing, is in the act of deception. Your eyes tell you it’s dirt (yuck), but your brain tells you that you’re in a fancy restaurant, so this must be some tasty faux dirt (which your tongue subsequently confirms). This act is less about taste than about the pleasure we derive from being deceived
  • Wealthy ancient Romans delighted in things that were not as they appeared. Emperor Nero’s banquet room featured a ceiling that rotated in imitation of the motion of the celestial bodies, or with hidden panels that could be withdrawn to shower guests with flower petals. He liked to hide gems in one’s dinner, which was a great treat, as long as you didn’t bite down too hard. In Satyricon, Petronius tells us of a feast thrown by Trimalchio, where guests were served “A hare done up with wings to look like Pegasus, a wild sow with its pregnant belly full of live thrushes, quinces bristling thorns so they looked like sea urchins, and roast pork sculpted into the shapes of fish, song birds, and a goose.” In the Middle Ages and Renaissance, famous artists, including Flemish master Jan van Eyck, were tasked with designing elaborate banquet centerpieces, like pies with living birds trapped inside. Whether or not the guests would want to eat a cake that living birds had recently occupied, no doubt scared out of their wits and likely pooping ferociously, is another matter. The pleasure was in the deception.

These days, accuracy and sharpness are the only things lenses seem to offer. This is great if you are photographing the bold colors of fruit sellers in India with, but that ıs nothing new to offer to the world of photography. For this very reason, I choose to use the current version of Leica Summicron 90mm f/2.0 APO when I wish to take portraits which only tell the story of the person without any additional characteristic introduced by the lens.

  • Leica Summicron 90mm f/2.0 APO ASPH is one of Leica's current model of telephoto lenses. It is a medium telephoto lens placed between the 75mm and 135mm lenses in production.
  • Currently, Leica produces Summarit series with f/2.4 and f/2.5 which are a little slower than Leica Summicron 90mm f/2.0 APO. Summarit lenses don't feature APO or aspherical coating on lens surface which contribute to lower pricing by Leica.

  • Leica Summicron f/2.0 APO was designed by Peter Karbe who was also the designer of Leica's  legendary Noctilux 50mm f/0.95 lens. This lens reflects his approach to lens design which ıs sharp, clear and very accurate and represents a deviation from the lenses manufactured in the past by Leica.

11 Feb 2016: Gravitational waves emitted by the merger of two black holes have been detected, setting the course for a new era of observational astrophysics.

about 21 hours ago

11 Feb 2016: On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from 35 to 250 Hz with a peak gravitational-wave strain of 1.0×10−21. It matches the waveform predicted by general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole. The signal was observed with a matched-filter signal-to-noise ratio of 24 and a false alarm rate estimated to be less than 1 event per 203 000 years, equivalent to a significance greater than 5.1σ. The source lies at a luminosity distance of 410+160−180  Mpc corresponding to a redshift z=0.09+0.03−0.04. In the source frame, the initial black hole masses are 36+5−4M⊙ and 29+4−4M⊙, and the final black hole mass is 62+4−4M⊙, with 3.0+0.5−0.5M⊙c2 radiated in gravitational waves. All uncertainties define 90% credible intervals. These observations demonstrate the existence of binary stellar-mass black hole systems. This is the first direct detection of gravitational waves and the first observation of a binary black hole merger.

11 Feb 2016: One of the puzzling aspects of compliance is that it means vastly different things across industries. What compliance means to a bank is very different from what compliance means to a drilling company.

  • I think the reasons are obvious: regulatory requirements.
  • In a highly regulated industry, there will be a greater focus on complying the regulatory mandate. A broker-dealer compliance officer is going to be focused primarily on the FINRA rules for broker dealers. An investment adviser compliance officer is going to be focused on compliance with its regulatory scheme. A drilling company is going to be focused on a different set of rules.
  • I see the difference in the junk mail I receive each day. I get flyers on FCPA compliance, OSHA compliance, Clean Water Act compliance… Someone is clearly checking the compliance box without thought to the substance behind it.

11 Feb 2016: Einstein published the first papers predicting the existence of gravitational waves — ripples in the fabric of space-time — almost a century ago. Physicists at the recently upgraded Laser Interferometer Gravitational-Wave Observatory (LIGO) have announced that they have measured these cosmic deformations, opening up a new field of gravitational-wave astronomy. Discover Nature’s coverage of the unfolding story and other gravitational-wave experiments, as well as everything you ever wanted to know about Einstein’s general theory of relativity.

I recently started using Duolingo to learn French. I don't know if any of you have used it, but I really enjoy it and it seems to be pretty effective -- and the user experience is very good; see, e.g., UX3488: User Onboarding | A frequently-updated compendium of web app first-run experiences. see https://en.duolingo.com/

Feb 2016: Learning with Duolingo is fun and addictive. Earn points for correct answers, race against the clock, and level up. Our bite-sized lessons are effective, and we have proof that it works.

JSON 7

Feb 11, 16

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.

    • JSON is built on two structures:

       
         
      • A collection of name/value pairs. In various languages, this is realized  as an object, record, struct, dictionary, hash table, keyed list, or  associative array.
      •  
      • An ordered list of values. In most languages, this is realized as an array,  vector, list, or sequence.
  • In JSON, they take on these forms:

     

    An object is an unordered set of name/value pairs. An object  begins with { (left brace) and ends  with } (right brace). Each name is followed  by : (colon) and the name/value pairs are  separated by , (comma).

  • An array is an ordered collection of values. An array begins  with [ (left bracket) and ends  with ] (right bracket). Values are separated  by , (comma).

9 Feb 2016: On its surface, the critically lauded Coen brothers movie Hail, Caesar! is a fantastical retro caper comedy (with musical numbers!) and a star-packed ensemble cast. On another level, it’s a meta-meditation on Hollywood and the dirty work that goes into the glossy final product. The biggest whitewash is splashed over the protagonist, Capitol Studio’s fixer Eddie Mannix, based on a real-life MGM executive with the same name, but with an important difference. While Josh Brolin's tightly wound but decent Mannix is played for laughs, the real Eddie Mannix wasn’t funny at all.

  • Caesar! follows the milder, fictional Mannix on a busy day and night in 1951 as he sorts out all manner of troubles involving a dizzying array of stars and movie genres: he brainstorms solutions to the inconvenient out-of-wedlock pregnancy of an Esther Williams-ish star (Scarlett Johansson). Hail, Caesar!’s Mannix also deals with the kidnapping of Baird Whitlock, (George Clooney) the star of an epic (and epically expensive) biblical story who is being held for ransom by a group of money-hungry communist writers called “The Future.”

           
     
     
  • Under Strickling and Mannix, the studio made problems disappear. Clark Gable kept Strickling and Mannix very busy. They were either telling papers he had been hospitalized for stomach problems when he was instead having his teeth replaced by less-charming dentures or cleaning up car wrecks, including one in which Gable may have killed a pedestrian. Actress Loretta Young became pregnant after an encounter with Gable during the filming of 1935’s Call of the Wild (Young later called the incident rape.) Mannix and Strickling helped hide Young from view during her pregnancy and then arranged for her to “adopt” her own child, just as Johannson’s character does in Hail, Caesar!.
  • “Gable loved Eddie,” says Fleming. “He was like Eddie. He wasn’t very educated, he was a hard working guy, but he was completely amoral.”

10 Feb 2016: How fitting that the first debate of the 2016 Turncoats series, with its proposition “Ornament is crime is crime”, took place in London’s Hoxton Hall, an East End music hall built in 1863 to provide entertainment for the working population but repurposed in 1879 by a temperance group to promote abstinence and restraint – presumably to much the same audience.

  • How fitting that the first debate of the 2016 Turncoats series, with its proposition “Ornament is crime is crime”, took place in London’s Hoxton Hall, an East End music hall built in 1863 to provide entertainment for the working population but repurposed in 1879 by a temperance group to promote abstinence and restraint – presumably to much the same audience.

     

  • There is more than a hint of the vaudeville in the Turncoats format, which pits opposing teams of speakers against one another in traditional style but with the theatrical twist that you’re not quite sure who’s playing true to type and who devil’s advocate. Previous debates in the series have included Quit Architecture Now and Vanity Publishing: a distinct departure from the “lukewarm love-ins” that the organisers feel characterise far too much of architecture’s public discourse today. To prime the audience, Turncoats events kick off with a comedy warm-up act and the downing of freely available vodka shots is enthusiastically encouraged.
  • This debate was expertly chaired by the highly un-impartial Charles Holland of Ordinary Architecture, hitherto partner at FAT, the (now sadly defunct) practice fêted for its clever and witty undermining of the orthodoxies of modernism in projects such as A House for Essex with artist Grayson Perry. Holland immediately christened the anti-ornament team “the hair-shirted whisperers”.

8 Feb 2016: I have always been intrigued by BoShek. When Ben Kenobi enters the cantina on Mos Eisley looking for a pilot to take himself, the boy and two droids to Alderaan, his first choice is a smuggler sporting arched eyebrows, killer muttonchops, and a black and white space suit more akin to an astronaut than a fighter pilot. While we cannot hear their dialogue, it is obvious that Kenobi asks him for a ride to Alderaan–and for whatever reason, the space pilot says no.

  • Whatever the reason, BoShek turns down the offer, but smoothly motions over his shoulder to the furry beast behind him, in my mind saying something to the effect of “Sorry, I can’t help you. But why don’t you give him a try?”
  • That furry beast, Chewbacca, then brings Kenobi and Skywalker to the table, Han Solo sits down, the rest is history…and BoShek faded forever into the darkness of the Mos Eisley bar.
  • So as I sat with my daughter in the Anaheim Convention center listening to Tom Spina and Pablo Hidalga’s fantastic panel “Secrets of the Mos Eisley Cantina,” I was shocked to discover that we had no idea who the actor was who played BoShek.

9 Feb 2016: The vulnerability is the result of apps that use a vulnerable version of Sparkle along with an unencrypted HTTP channel to receive data from update servers. It involves the way Sparkle interacts with functions built into the WebKit rendering engine to allow JavaScript execution. As a result, attackers with the ability to manipulate the traffic passing between the end user and the server—say, an adversary on the same Wi-Fi network—can inject malicious code into the communication. A security engineer who goes by the name Radek said that the attack is viable on both the current El Capitan Mac platform and its predecessor Yosemite.

  • Apps that use 3rd-party updater over insecure HTTP channels subject to MiTM attacks.
  • Camtasia, uTorrent, and a large number of other Mac apps are susceptible to man-in-the-middle attacks that install malicious code, thanks to a vulnerability in Sparkle, the third-party software framework the apps use to receive updates.
