Slashdot: The Passenger Pigeon: A Century of Extinction

Slashdot (posted on Monday September 01, 2014 at 20:13 AWST)

An anonymous reader writes On September 1, 1914, Martha, the last passenger pigeon was found dead in her aviary at the Cincinnati Zoo. When the first European settlers arrived in North America at least one of every four birds on the continent was a passenger pigeon, making them the most numerous birds in North America, and perhaps in the world. From the article: "But extinction apparently doesn't ring with the finality it used to. Researchers are working to 'de-extinct' the bird. They got their hands on some of the 1,500 or so known passenger pigeon specimens and are hoping to resurrect the species through some Jurassic Park-like genetic engineering. Instead of using frog DNA to fill out the missing parts of a dinosaur's genetic code as in Michael Crichton's story, the real-life 'bring-back-the-passenger pigeon' researchers are using the bird's closest relative, the band-tailed pigeon.

An anonymous reader writes New Zealand is facing its weirdest election ever with a hacker calling himself "Rawshark" progressively dumping emails hacked from a controversial blogger. This weekend, revelations forced the resignation of one Government minister and nobody knows what will drop next. Emails revealed that the blogger, called "Whale Oil", was in contact with both a government minister in charge of New Zealand's white collar crime investigations unit and with a PR man acting for a founder of a failed finance company then under investigation.

DP Review: Cold War camera: 1950s Berlin in color (part 1)

DP Review (posted on Monday September 01, 2014 at 17:00 AWST)

Ten years after the end of WWII, Germany was rebuilding. Cities like Berlin, which had been severely damaged during the war were emerging from the rubble as the 'Wirtschaftswunder' or 'economic miracle' transformed West Germany. In the immediate post-war period hundreds of thousands of allied troops were stationed in the divided country, many of them with cameras. Found recently at a flea market, the images in this article date from 1956-7 and were taken by a US Serviceman in Berlin. Click through to take a look

Slashdot: Yahoo Stops New Development On YUI

Slashdot (posted on Monday September 01, 2014 at 06:52 AWST)

First time accepted submitter dnebin writes Yahoo announced that they will cease new development on their javascript framework YUI, bowing to industry trends towards Node.js, Angular, and others. The announcement reads in part: "The consequence of this evolution in web technologies is that large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don't want to be locked into. As a result, the number of YUI issues and pull requests we've received in the past couple of years has slowly reduced to a trickle. Most core YUI modules do not have active maintainers, relying instead on a slow stream of occasional patches from external contributors. Few reviewers still have the time to ensure that the patches submitted are reviewed quickly and thoroughly."

Too bad those trains have nowhere to go. Putting the cart before the horse, the U.S. Department of Energy recently asked companies for ideas on how the government should get the rail cars needed to haul 150-ton casks filled with used, radioactive nuclear fuel. They won't be moving anytime soon. The latest government plans call for having an interim test storage site in 2021 and a long-term geologic depository in 2048. No one knows where those sites will be, but the Obama administration is already thinking about contracts to develop, test and certify the necessary rail equipment.

Digital Photography School: Interview: Oded Wagenstein – Author of Snapn Travel Guide and dPS Writer

Digital Photography School (posted on Monday September 01, 2014 at 03:00 AWST)

Oded Wagenstein interview

Oded Wagenstein is a travel photographer and writer. He’s built a reputation taking intimate portraits from around the world and is a regular contributor to National Geographic Traveler magazine (Hebrew edition).

Regular readers will be familiar with Oded’s wonderful photography and articles. We’re interviewing him here at dPS because we have just published his new ebook about travel photography.

Oded Wagenstein interviewIt’s called Snapn Travel – A lifetime of travel memories in a snap, and it’s available from our sister site Snapn Guides. It’s a fantastic ebook that will help any photographer who is planning a trip to another country to take better photos while they are there.

In Snapn Travel Oded writes about the importance of creating images that tell stories. He explores the process that he undertakes on any travel assignment, from initial research to working in the field, to come away with powerful and evocative images. We’ll delve a little deeper into some of those topics in this interview.

The Interview

In your ebook you start by saying that travel photography is all about portraying the stories and emotions we find during our journeys. Can you elaborate on those ideas? How does one go from taking snapshots of places you see on your travels to taking photos that make full use of emotion and story?

Oded: Travel photography is almost as old as photography itself. Magazines and commercial photo publishers used to send travel photographers like Francis Bedford and James Ricalton to “exotic” places in the east to bring back some of that “oriental flavor” that everyone in the west was so badly after in the nineteenth century. Even until recently, if you visited a remote tribe in Africa and got an image of someone with a bone through his nose, you got yourself a “worthy” image.

But those days are over! We live in an era of digital photography, where cameras are so common, that even this tribe might have its own smartphone camera. Today, it is really hard to create fresh images that the world hasn’t yet seen. So, from my point of view, today, an image alone is not enough, as you must be able to tell a visual story. Don’t show me India, I know how India looks, tell me how traveling in India felt for you. If you want to sum up my philosophy: shoot what you feel and make your viewer feel the same.

Oded Wagenstein interview

A lot of your photos are portraits. How do you find willing subjects for your portraits when travelling?

Oded: Portrait photography is a “give and take” relationship, not “take and take”. I try to make it as fun as possible for the person I photograph. If he wants to tell me a story, I listen, and always do my best to send the photo to him. I make the process a conversation, and not a photo shoot. This lets my subject forget about the camera.

One of the most important skills I learned is to ask a person a question, shoot while he’s answering, and while I’m thinking about the next question. This makes everything natural and “flow”. Portrait photography is so much more than controlling aperture and shutter speed.

Oded Wagenstein interview

How do you overcome obstacles such as language differences or suspicion of foreigners?

Oded: I always travel with a fixer, who is a local that can serve as a guide and translator.

How do you become involved with the people that you meet? How do you come across as a traveller who is genuinely interested in people rather than a tourist who perhaps sees the local people as little more than subject for photos?

Oded: First, as obvious as it may sound, I am really interested in them. The image for me is just a byproduct: a nice byproduct, but not the goal. I am an image maker because the camera helps me “see” the world in a better way. It lets me start a conversation with a stranger, and maybe have a cup of tea with them. The camera is my bridge to the world and besides being interested in the person’s story, I always try to get inside the story and not watch it from outside. For example, once I was invited to a local Tajik wedding. I took a few pictures but then put the camera down and got on the dance floor. The next time I took out my camera, the pictures were much better.

Oded Wagenstein interview

Can you talk us through the differences between working on an official magazine shoot and going to a location purely under your own initiative?

Oded: I treat both scenarios exactly the same way. In both, the responsibility to come back with the best results is all on the photographer’s shoulders and no one can tell you exactly what to shoot and where to go. The magazine can help you with ideas or hiring a fixer (local guide), but you are your own boss, for better and for worst.

I do my visual research and learn about the culture (history, food, music, religion, etc.). On the ground, I hire a fixer and do my best to come back with the best images, even if it takes me long days, hard walks, and enduring extreme weather.

In my travel photography workshops, I always refer my students to the “client”. From my point of view, we all, professional and amateurs alike, have clients. Our clients are our viewers and friends, and I treat my Facebook viewers and my magazine editor with the same amount of effort and professionalism.

Oded Wagenstein interview

I like this piece of advice: “Discover things not commonly photographed and your stories will always be two steps ahead of the crowd.” Can you explain this in a little more depth? How do you find the things that are not commonly photographed?

Oded: You don’t have to travel far, or trek for miles, to find those places. You just need to think outside the box. For example, I did a story not long ago on Bollywood. India is so complex and rich, but I think that we always see the same things about the country: poor people in really colorful clothes. So I wanted to show a different side of India: rich and glamorous.

My students struggle to find interesting things to photograph in their own towns. And I tell them that one’s ordinary breakfast or road to work is another’s “exotic” country.

Oded Wagenstein interview

Last year I spent a week in the north of New Zealand’s South Island. I took some landscape photos but I wasn’t really happy with the results. It made me realixe just how hard landscape photography can be – you’re relying on the weather and light to do its part, and in many ways as a photographer, your hands are tied. You have to work with the landscape as it is, and (digital manipulation aside) there is nothing you can do to change it. Bearing in mind there isn’t much happening in a cultural sense in this part of the world, what advice would you give me if I was to go back to the same place and try again? How can I move from taking uninspiring landscape photos to finding and telling an interesting story?

Oded: This is a good question. Here you have two approaches:

The passive approach, or coming at the right time. Just come in the right season, the right day, at the right time. Say a cloudy winter day with golden rays of sunrise.

The active approach, or creating the right time. Good lighting is always needed, but bring a tripod, a good looking hat, a backpack, and capture yourself enjoying the view. You will see how the image becomes better because you added a “main hero” to the image and because people love watching other people. Don’t avoid people in your landscape photography, that’s my advice.

Oded Wagenstein interview

Traveling to a distant and exotic location is one thing, but given that most people can only spend a short time of the year doing this, what about the idea of travel photography in your own back yard?

Oded: Buy the Lonely Planet guide (or any other guide book) on your own country and travel by it. Take a silly tourist’s hat and view some postcards. See your own back yard as a tourist. Think of places you have special access to – maybe there is an interesting story or a person in your family (I have a few), maybe your job is not ordinary, and maybe your mother just cooked a local dish that I, as a foreigner, would love to see.

Do you have any questions for Oded about travel photography? Please let us know in the comments. And don’t forget to check out Snapn Travel – A lifetime of travel memories in a snap.

Anna Merikin writes In 1964, Richard Feynman delivered a series of seven hour-long lectures at Cornell University which were recorded by the BBC, and in 2009 (with a little help from Bill Gates), were released to the public. The three-volume set may be the most popular collection of physics books ever written, and now the complete online edition has been made available in HTML 5 through a collaboration between Caltech (where Feyman first delivered these talks, in the early 1960s) and The Feynman Lectures Website. The online edition is "high quality up-to-date copy of Feynman's legendary lectures," and, thanks to the implementation of scalable vector graphics, "has been designed for ease of reading on devices of any size or shape; text, figures and equations can all be zoomed without degradation." Volume I deals mainly with mechanics, radiation and heat; Volume II with electromagnetism and matter; and Volume III with quantum mechanics. Last year we told you when Volume I was made available.

Digital Photography School: Understanding Masking in Photoshop

Digital Photography School (posted on Sunday August 31, 2014 at 22:04 AWST)


Masking is one of those techniques that will change the way you use Photoshop. Understanding this technique can help you to jump from being a beginner level Photoshop user, to a more advanced one. In this article, I will explain how masking really works in Photoshop, its few key concepts, and how Masking helps you to perform non-destructive editing.

The skills you need to get started masking in Photoshop are being able to use the brush tool to paint color, understand two colors black and white, and knowledge of how layers work in Photoshop, which I assume you have very sound knowledge on.

What is masking what does it do in Photoshop?

If you can relate the word masking with the mask, it may make some sense. Why do we use a mask, to cover the face, right? So why would we use masking on a layer, to cover or uncover the content of any layer. With a mask you can control the transparency of a layer. But that is what opacity and fill is for, right? Yes, opacity and fill do control the transparency, but it works for whole layer. What if you would like to have only the right part to be transparent and the left part to be completely visible? That’s when masking comes into play.

Masking works in two ways. First, you simply add a mask on any layer by clicking the third option on the bottom of layer palette. The other way is by using adjustment layers, which always comes with a mask.

Background without mask

This image shows a layer with no mask applied. I have highlighted the third option on the layer palette. That is where you add a mask.

Adding mask white

Clicking on the mask option will create a white layer mask on the layer selected.

Adjustment layer

This image shows an adjustment layer. They help you to perform non-destructive editing, and every adjustment layer created this way, comes with a white mask.

Adjustment layer with white mask

This shows that a new curve adjustment layer has been applied with the white mask.

While working with masking please remember that white shows the content where as black hides. If your mask is white, the mask is transparent and the layer is fully revealed, whereas if the mask is black it is opaque and the layer below will show through. Below are a few examples that will help you to understand masking better.

A handy saying to help you remember: white reveals, black conceals

White mask

The image above shows, that the white mask reveals the content of the layer it is affecting. I duplicated the background layer and desaturated it with Shift+Command+U on a Mac (Shift+Control+U on PC).

Black mask

With Ctrl/Cmd+I, you can invert the white mask into a black one. Since black hides the effects, the image has now been changed from back and white to color, from its original state (the layer below is now visible)

When you first add a mask it will initially be white, but you can change it into black either by inverting the mask, Cmd/Ctrl+I, or you can fill with black or white. Alternately, by simply pressing Alt while clicking to create the mask would also result in a black mask.

Creating black mask

Additional tip

  • Step 1. First click D on your keyboard (default), which will fill your background color with white, and foreground color with black.
  • Step 2 Select the mask
  • Step 3 Press ALT+Backspace to fill with the foreground color (black) and Ctrl+Backspace for to fill with the background colour (white). You can use X to swap the foreground and background colors.

You can now paint on the mask with the brush key selected. Make sure your foreground color is opposite to the color of the mask. If you are painting with black on a white mask, the content of that part of layer is becoming transparent while the white parts remain as is. If you are painting white over a black mask, then that part would be back to its original form. You can play around with the percentage of fill and opacity to get more control over your workflow.

Painting with black on mask

Here I painted the guitar with a black brush over the white mask, resulting in the visibility of color from the layer below.

Additional tip

Simply press your number on the number pad and your opacity will change as per. If you press shift plus the number, then its fill will change.

  • 4=40%
  • 4+9= 49%
  • 0+4 = 4 %

Do you have any other masking tips and tricks? Please share in the comments below if you do, or if you have any questions.

Slashdot: Battle of the Heavy Lift Rockets

Slashdot (posted on Sunday August 31, 2014 at 20:28 AWST)

schwit1 writes: Check out this detailed and informative look at the unspoken competiton between NASA's SLS rocket and SpaceX's planned heavy lift rocket. It's being designed to be even more powerful than the Falcon Heavy. Key quote: "It is clear SpaceX envisions a rocket far more powerful than even the fully evolved Block 2 SLS – a NASA rocket that isn't set to be launched until the 2030s." The SpaceX rocket hinges on whether the company can successfully build its new Raptor engine. If they do, they will have their heavy lift rocket in the air and functioning far sooner than NASA, and for far less money.

DP Review (posted on Sunday August 31, 2014 at 17:00 AWST)

While it's easy to get swept up in the stream of product announcements at this time of year, it's also a good idea to remember why we buy that gear - to make great photos. What better way to do it than to showcase the excellent work of our own community? This week we asked users of our Black and White Photography forum to submit their favorite shots for inclusion in our Readers' Showcase. As usual, the photos submitted were of a very high quality. See gallery

Slashdot: RAYA: Real-time Audio Engine Simulation In Quake

Slashdot (posted on Sunday August 31, 2014 at 14:26 AWST)

New submitter bziolko writes: RAYA is a realtime game audio engine that utilizes beamtracing to provide user with realistic audio auralization. All audio effects are computed based on the actual geometry of a given game level (video) as well as its acoustic properties (acoustic materials, air attenuation). The sound changes dynamically along with movement of the game character and sound sources, so the listener can feel as if they were right there — in the game.

Slashdot: Anand Lal Shimpi Retires From AnandTech

Slashdot (posted on Sunday August 31, 2014 at 11:36 AWST)

An anonymous reader writes: If you've built a PC in the past 17.5 years, chances are you read some hardware reviews on AnandTech at some point. The site's creator, Anand Lal Shimpi, has announced that he is retiring from the tech writing business. He said, "AnandTech started as a site that primarily reviewed motherboards, then we added CPUs, video cards, cases, notebooks, Macs, smartphones, tablets and anything else that mattered. The site today is just as strong in coverage of new mobile devices as it is in our traditional PC component coverage ... To the millions of readers who have visited and supported me and the site over the past 17+ years, I owe you my deepest gratitude. You all enabled me to spend over half of my life learning more than I ever could have in any other position. The education I've received doing this job and the ability to serve you all with it is the most amazing gift anyone could ever ask for. You enabled me to get the education of a lifetime and I will never be able to repay you for that. Thank you."

Slashdot: Microsoft Defies Court Order, Will Not Give Emails To US Government

Slashdot (posted on Sunday August 31, 2014 at 08:02 AWST)

schwit1 sends this excerpt from a report about Microsoft: Despite a federal court order directing Microsoft to turn overseas-held email data to federal authorities, the software giant said Friday it will continue to withhold that information as it waits for the case to wind through the appeals process. The judge has now ordered both Microsoft and federal prosecutors to advise her how to proceed by next Friday, September 5. Let there be no doubt that Microsoft's actions in this controversial case are customer-centric. The firm isn't just standing up to the US government on moral principles. It's now defying a federal court order. "Microsoft will not be turning over the email and plans to appeal," a Microsoft statement notes. "Everyone agrees this case can and will proceed to the appeals court. This is simply about finding the appropriate procedure for that to happen."

Slashdot: Wi-Fi Router Attack Only Requires a Single PIN Guess

Slashdot (posted on Sunday August 31, 2014 at 06:53 AWST)

An anonymous reader writes: New research shows that wireless routers are still quite vulnerable to attack if they don't use a good implementation of Wi-Fi Protected Setup. Bad implementations do a poor job of randomizing the key used to authenticate hardware PINs. Because of this, the new attack only requires a single guess at the hardware PIN to collect data necessary to break it. After a few hours to process the data, an attacker can access the router's WPS functionality. Two major router manufacturers are affected: Broadcom, and a manufacturer to be named once they get around to fixing it. "Because many router manufacturers use the reference software implementation as the basis for their customized router software, the problems affected the final products, Bongard said. Broadcom's reference implementation had poor randomization, while the second vendor used a special seed, or nonce, of zero, essentially eliminating any randomness."

Slashdot: Google's Megan Smith Would Be First US CTO Worthy of the Title

Slashdot (posted on Sunday August 31, 2014 at 05:40 AWST)

theodp writes: Bloomberg is reporting that Google X's Megan Smith is the top candidate for U.S. Chief Technology Officer. With a BS/MS in Mechanical Engineering from MIT, and experience ranging from General Magic to Google, Smith would arguably be the first U.S. CTO worthy of the title (the outgoing U.S. CTO has a bachelor's in Econ; his predecessor has a master's in Public Policy). "Smith joined Google in 2003. As vice president of business development, she oversaw many of its most important acquisitions, like Keyhole, the service that underlies Google Earth. She has led the company’s philanthropic division,, and served as a co-host for Google’s Solve for X forum, where distinguished thinkers and scientists brainstorm radical technology ideas with Google executives."
