As a child, I always looked up at the stars and wondered how I could make it into space. Hopefully, I will live to see that day, but for now, a homemade satellite will have to do. The Nanosatisfi team has made it their mission "to provide affordable space exploration for everyone!," and with ArduSat, they move one step closer to reality. ArduSat is a Arduino-controlled miniature 10cm cubic satellite, weighing 1 kg, which is roughly equivalent to half a store bought loaf of bread. Its size might not be impressive, but it packs over 25 sensors including: Myspectral's open source spectrometer, inertial measurement unit, magnetometer, along the standard set, and many others. This impressive little machine boasts a camera to take photographs, it could send messages back to earth, or it can run your space experiments. With the ability to upload code directly to the ArduSat while in space, the possibilities are virtually limitless.

Robert Harvey asks: Occasionally I see questions about edge cases on Stack Overflow that are easily answered by the likes of Jon Skeet or Eric Lippert-experts who demonstrate a deep knowledge of a particular language and its many intricacies. Here's an example of this from Lippert's MSDN blog: You might think that in order to use a foreach loop, the collection you are iterating over must implement IEnumerable or IEnumerable. But as it turns out, that is not actually a requirement. What is required is that the type of the collection must have a public method called GetEnumerator, and that must return some type that has a public property getter called Current and a public method MoveNext that returns a bool. If the compiler can determine that all of those requirements are met then the code is generated to use those methods. Only if those requirements are not met do we check to see if the object implements IEnumerable or IEnumerable. This is cool stuff to know. I can understand why Eric knows this; he's on the compiler team, so it's explicitly in his job description to know. But how do mere mortals, those of us on the outside, find out about stuff like this?

"Businesses invest billions of dollars annually in market research studies developing and testing new ideas by asking consumers questions they simply can't answer. Asking consumers what they want, or why they do what they do, is like asking the political affiliation of a tuna fish sandwich. That's because neuroscience is now telling us that consumers, i.e., humans, make the vast majority of their decisions unconsciously. Steve Jobs didn't believe in market research. When a reporter once asked him how much research he conducted to develop the iPad, he quipped, "None. It isn't the consumers' job to know what they want." And according to some measures, the iPad became the most successful consumer product launch ever and Apple went on to become the most valuable company of all-time."

There is no proverbial silver bullet to creating a safer city, but analytics technology is assisting law enforcement agencies all over the world to sort through information - part of the 2.5 quintillion bytes of data we create and consume every day - to get ahead of crime. Having access to all that information is an invaluable resource for law enforcement agencies, but it can also be pretty paralyzing. After all, only a fraction of the bits and bytes can actually be relevant, right? But how do you know and, more importantly, how do you find and act on it?

"Someone points me to this report from Tilburg University on disgraced psychology researcher Diederik Stapel. The reports includes bits like this: When the fraud was first discovered, limiting the harm it caused for the victims was a matter of urgency. This was particularly the case for Mr Stapel's former PhD students and postdoctoral researchers . . . However, the Committees were of the opinion that the main bulk of the work had not yet even started. . . . Journal publications can often leave traces that reach far into and even beyond scientific disciplines. The self-cleansing character of science calls for fraudulent publications to be withdrawn and no longer to proliferate within the literature. In addition, based on their initial impressions, the Committees believed that there were other serious issues within Mr Stapel's publications . . . This brought into the spotlight a research culture in which this sloppy science, alongside out-and-out fraud, was able to remain undetected for so long. . . . The scientific literature must be cleansed of everything that is fraudulent, especially if it involves the work of a leading academic. Sounds familiar? I think it also applies to recipients of the Founders Award from the American Statistical Association. There's more: The most important reason for seeking completeness in cleansing the scientific record is that science itself has a particular claim to the finding of truth. This is a cumulative process, characterized in empirical science, and especially in psychology, as an empirical cycle, a continuous process of alternating between the development of theories and empirical testing. . . . My first reaction was that all seems like overkill given how obvious the fraud is, but given what happened with comparable cases in the U.S., I suppose this "Powell doctrine" approach (overwhelming force) is probably the best way to go."

Last year Golan Levin's son decided to build a car. Aside from the minor inconvenience of being 4 years old, the younger Levin faced an engineering challenge. His Tinkertoys, which he wanted to use for the vehicle's frame, wouldn't attach to his K'Nex, the pieces he wanted to use for the wheels. It took his father, an artist, hacker and professor at Carnegie Mellon, a year to solve that problem. In the process he cracked open a much larger one: In an age when anyone can share, download and create not just digital files but also physical things, thanks to the proliferation of cheap 3-D printers, are companies at risk of losing control of the objects they sell?

With the Oscars just 3 days away, movies have been on our mind lately here at CDC's Office of Public Health Preparedness and Response.  Especially disaster movies.  They come in all kinds of flavors: deadly viruses, tornadoes, earthquakes, and, yes, even snakes on a plane.   Their special effects can be realistic enough to make us feel like we are right there in the heart of the storm.  But frequently, the heroes and heroines of these movies respond to disasters in ways that bear no resemblance to what people in the real world should do.  We can nevertheless use disaster films to consider how the characters could have been more prepared or how they should have reacted if the situation they faced was real.  Check out some of our favorite disaster movies and the lessons we can learn from them.

Each month Seattle-based Olson Kundig Architects' studio gets a makeover and the latest installation to be unveiled is a tented experimental mushroom farm! Design team CityLab7 collaborated with the architects to create an educational and interactive space that displays 215 oyster mushroom growbags, giving an example of how small-scale urban farming really works. As an homage to a city renowned for its coffee culture, visitors to the space will also see how coffee grounds donated from local cafes can be recycled into compost, becoming an essential component of city agriculture.

Note-I am going to try this for our blog. If you've ever wondered how some website that looks like it was an early draft from the proverbial infinite number of monkeys on infinite keyboards managed to get to the top of a search result page instead of something you actually want to read (or something you've written), you've been victimized by the dark art of search engine optimization (SEO). In the never-ending battle for the top of the Google search results page, and for advertising click-throughs, marketers and bloggers enlist an ever-changing bag of tricks to game search engine algorithms, often with the help of SEO consultants and a collection of tools that track the best tactics of the moment.

Learning to code is becoming the key skill for anyone who wants to launch a tech startup, or even just get a job working at a hot tech company. That may seem intimidating, but programming is not some monumental skill that only specially gifted people can learn. Really, it it isn't all that different from learning to speak another language. If you can pick up the rudiments of Spanish or French in a couple of weeks, how hard could it be to get started with Ruby On Rails? The Developer Bootcamp is designed to help anyone get started coding - and they might even get a job at a startup or tech heavyweight out of it as well.

I went to the GLUE conference to get in over my head. That was my entire goal. I wanted to learn about the technology that helps to stitch together the various parts of the Internet, but I also wanted to spend some time getting to know the people who made that technology do what it does. Over the course of 2 days I met people who made me feel dumb, saw thousands of lines of code and left with a new appreciation for how technology works.

Here's some bad news for those of you who like to think you can think rationally about risk. You can't. You know all those thoughtfully considered views you have about nuclear power or genetically modified food or climate change? They are really no more than a jumble of facts, and how you feel about those facts. That's right. They're just your opinions. Which is bad news, because no matter how right you feel, you might be wrong. And being wrong about risk is risky, to you AND to others.

This handbook discusses the legal, social and technical aspects of open data. It can be used by anyone but is especially designed for those seeking to open up data. It discusses the why, what and how of open data - why to go open, what open is, and the how to 'open' data.

"Dropbox is holding a promotion for students in which you can gain 3GB of extra Dropbox space for two years, plus more depending on how many people in your school sign up. To sign up for Dropbox's "Great Space Race," all you need to do is head to the link below and type in a valid .EDU email address (which you probably have even if you aren't a student anymore). After you confirm it, you should see 3 extra GB of space in your account. If you get others at your school to sign up too, you'll get even more space, going all the way up to 25GB. So sign up, tell your friends, and invite them if you haven't already for bigger bonuses!"

Results from FIA Aalborg: The Internet of Things (IoT) is one of the most important fundaments for the smart cities, and is becoming slowly but steadily one of the core elements of the Future Internet (FI). In fact, various architectures and approaches from Future Internet such as Cloud Computing (Software as a Service - SaaS), which are being linked with the Web of Things, which is also allowing to define Sensors as a Service (SaaS) are clear examples of this relation between Future Internet and IoT architectures. At this particular point, where the IoT is a reality, where several IoT-based high scale deployments are being carried out such as Rome, and Santander. It is essential to discuss what are the IoT-specific aspects that the FI architecture has to take into account, in order to efficiently map the IoT architectures into an overall FI architecture, and particularly, how to manage rights of the individual (i.e. privacy) and its interaction with IoT objects taking into account aspects like delegation, access control as key aspects in the inclusion of the Internet of Things in the common lives with its total inclusion in the city of the future.

"Academia.edu, a social network for scholars, is unveiling a new feature today that its founder Richard Price hopes will help address part of the "credit gap" for research. Academia.edu allows users to upload and share their research papers, and the site is launching its Analytics Dashboard for Scientists today that Price says will let scholars see the "real-time impact" of their work. Academic publishing has long been a black-box in terms of both who's reading and who's citing. Publishing in journals may be expected (required, even), but the delays in the publishing process can make it challenging to ascertain how much influence work has. "It typically takes about 3 to 5 years for citations to actually appear back in the process," argues Price, pointing to the lengthy time between researching, writing, peer-reviewing, and publishing."

Joey Hudy, a young "maker" from Phoenix went to the White House this week to show off his project, the "Extreme Marshmallow Cannon." When President Obama saw it, he told Joey: "Let's try it." Joey set up the air cannon, which uses a bicycle pump to build up air pressure, and put a marshmallow down the barrel. When he pressed the trigger, a single marshmallow was shot out across the room to the delight of everyone, but especially the president.

It may be difficult to imagine a world where human beings are even more connected than we are now. Yet the reality is that when it comes to connectivity, we're barely scratching the surface in terms of where we'll be in the future.

Memories can be reactivated during sleep and strengthened in the process,  Northwestern University research suggests. In the Northwestern study, research participants learned how to play two artificially generated musical tunes with well-timed key presses. Then while the participants took a 90-minute nap, the researchers presented one of the tunes that had been practiced, but not the other
