How birds spot the cuckoo in the nest

It's not always easy spotting the cuckoo in the nest. But if you don't, you pay a high price raising someone else's chick. How hosts distinguish impostor eggs from their own has long puzzled scientists. The problem remained largely unsolved while looking at it through our own eyes. It was only when people started thinking from the birds' perspective that they began to understand how hosts recognise a cuckoo egg in the nest. Marcel Honza from the Academy of Sciences of the Czech Republic explains that birds see UV wavelengths that are well outside our own visual range. Knowing that many bird eggs reflect UV wavelengths, Honza wondered whether altering the reflected UV spectrum of an egg would affect a bird's ability to recognise it as foreign and reject it.

How Do You Deal With Sensitive Data?

imus writes "Just wondering how most IT shops secure sensitive data (customer records). Most centrally managed databases seem to be monitored and maintained very well and IT workers know when they are tampered with or when unauthorized access occurs. But what about employees who do legitimate selects from these databases and then load CSV files and other text files onto their laptops and PDAs? How are companies dealing with situations where the database is relatively secure, but end-use devices contain bits and pieces of sensitive business data, and sometimes whole segments? Does anyone use sensitive data discovery software such as Find_SSNs or Senf or other tools? Once found, how do you deal with it? Do you force encryption, delete it or prevent extracts?"

To Stet Or Not To Stet, That Is the Question

theodp writes "The NY Times' Virginia Heffernan confesses to being stumped by how to excerpt the language on message boards and blogs. For example, Heffernan notes she could quote kavya on Yahoo Answers word for word ('How is babby formed? How girl get pragnent?'), but worries that doing so makes kavya look like an idiot rather that the sweetly earnest 7-year-old that he or she might be. Is it better to paraphrase or revise the question into 'How is a baby formed?' For now, Heffernan is going to let things stand (stet) and treat message boards like novels, preserving idiosyncrasies of language as far as possible and taking them as intentional — a 'wuz' on the Internet remains 'wuz' in the paper."

JavaScript: The Good Parts

Anita Kuno writes "JavaScript: The Good Parts is about the good parts of JavaScript and how to use them. This book takes a realistic look at the strengths and weaknesses of JavaScript and tells you how to use it to its best advantage. The code samples deal with the language and its merits — creating web pages is not discussed. How to understand the language, to execute the operations you want, is the focus of the book, not how to make rounded corners. The author, Douglas Crockford says, 'My microwave oven has tons of features, but the only ones I use are cook and the clock. And setting the clock is a struggle. We cope with the complexity of feature-driven design by finding and sticking with the good parts.'" Keep reading for the rest of Anita's review.

Test Drive a Solar Array's Wattage Before You Build With RoofRay Google Maps Calculator

Thinking of camping out at Ikea once they start selling those solar panels? While you're waiting, RoofRay will help you plan exactly how many SUNGLYÄSS units you'll need, and how much you'll save. Draw the shape of a prospective solar array on Google Maps' satellite image of your roof, enter its slope angle, and watch RoofRay calculate how much DC juice your panels will generate. It doesn't take into account exactly what kind of panels you'll be using, so of course it's an estimate, but an interesting tool for getting the general idea of how much you could knock off the electric bill. See it in action in a demo video below.

Do All MP3 Players Sound Alike?

"Recently I read a review of an mp3 player where the author purposely chose not to discuss sound quality because, in the author’s words, 'The chosen player has a great deal to do with how you access your music, but very little to do with how it sounds…' That got me thinking. Do all mp3 players sound alike? They are all digital, so it’s the same 1’s and 0’s playing the music, so how can there be a difference in sound quality? I have tested some mp3 players myself and have noticed drastic differences. I have trouble believing that mp3 players don’t influence sound quality that much. They have different components, circuitry, software and build tolerances, so how can there not be a difference?"

Ragnar Tornquist On Video Game Storytelling

Ragnar Tornquist is respected as one of the best storytellers in today's game industry. He's done work on Anarchy: Online, Dreamfall, and upcoming MMO The Secret World. Rock, Paper, Shotgun has a lengthy three-part interview with Tornquist about how good stories are crafted, how they interact with other aspects of the games, and what his preferences are for building a compelling character. "We had all these characters who were on a journey of faith, and we said how can we ensure that this theme is carried through, and have a clear view of how their journeys happen. So we said, every single major character had to fit into this model. Everybody starts out at the top. Faith can be anything — it can be religion, it can be a belief in yourself, in your abilities, in the work you do.
