The Past, Present, and Future of Data Storage As we approach the end of 2011 and look forward to another year, we pause to reflect on the long history of data storage. Mankind's ability to create, process, store, and recall information is light years ahead of the days of cave paintings and engravings on stone tablets. Vast amounts of information can be stored on drives smaller than your thumb, and data centers are cropping up at an increasingly high rate. What does the future of data storage hold? Are we really that close to holographic drives? Is 2012 the year SSDs become mainstream? Embed this image on your site:
MAP Pocket Boom Portable Vibration Speaker – Black | Review Thanks to MobileFun for sending this out to me for review. Pros: - Small and compact - Uses a small vibration pad - Can turn literally anything into a speaker Cons: - 3.5mm jack could be longer - Requires AAA batteries - Sticky pad can lose stickiness over time There is no doubt that there are many portable speakers out there. Pocket Boom is a speaker taking an entirely different approach to how sound is produced. That pad can be stuck to things like a plastic box or a desk to produce sound. It’s great when stuck to a desk and actually produces quite good bass. In the box you get two extra sticky pads because over time the pads can lose their stickiness. One big problem I have with this is that it requires batteries. You can use the speaker via USB however. The speaker is very ‘pocket-able’ as the name of it suggests. One other gripe is the 3.5mm headphone jack. Overall The Pocket Boom is a new way for little speakers to produce big sound and it does it well.
Graph Databases, published by O'Reilly Media Pedagogy meets Big Data and BIM – Big Data, Sensing and Augmented Reality: Paper and Key Note Presentation In June 2013 The Bartlett held a conference entitled ‘Pedagogy meets Big Data and BIM’. The conference brought together over 100 participants from across the United Kingdom, European Union and the United States from diverse backgrounds such as academic institutions, government and industry – including ARUP, Autodesk, Balfour Beatty, BAM, and Royal Institute of British Architects. The Faculty’s motivation to focus on BIM (Building Information Modelling) and Big Data (deriving from the exponential growth of the profession’s access to spatial statistics) was the realisation that innovation, collaboration and technology are rewriting industry practice in profound ways and must also reshape the built environment curricula. I was lucky enough to be asked to present the key note to the conference, below is the short paper produced along with the full key note presentation: Data Over the last 5 years there has been a turning point in the availability of data related to the urban environment.
Heads Up, Hoverboarders: Here Comes Quantum Levitation Few motifs of science fiction cinema have been more appealing to us than the subtle defiance of gravity offered by futuristic hovercraft. So every once in a while we check in to see how humanity is progressing on that front, and whether the promise of hoverboards will be delivered by 2015 as evidenced in Back to the Future Part 2. We’re not quite there yet, but we’re definitely getting off the ground, so to speak. Get ready to hover your brain around the art of quantum levitation. That’s right, quantum. Because of its chemical properties, a superconductor (when brought to low enough temperatures using, say, liquid nitrogen) exhibits this effect, causing the energy from the magnet below to warp around the superconductive object in a way which “locks” it in space. Even more impressive and ripe for practical transportation use: When the superconducting object is placed along a magnetic rail, it exhibits frictionless momentum. Connections:
Home | OrientDB Document-Graph NoSQL DatabaseOrientDB Document-Graph NoSQL Database Random Number Multiples About seven years ago, I had a bit of a career crisis. I was freelancing – working for clients I didn’t care much about on projects that I didn’t care much about, and feeling that there was a huge distance between the work that I was creating and my physical self. I was sick of computers, and was considering a range of (in hindsight) ridiculous vocational changes. My rescue didn’t come from a new programming language, or a faster computer, or even better clients. Imagine how happy I was, then, to be asked by curator Christina Vassallo to be part of the inaugural edition of her Random Number Multiple series – a project that would produce screenprints from the work of computational artists and designers. Marius and Christina and I spent three days at Bushwick Print Lab printing each of the 200 prints by hand. I made two prints. This print turned out even better than I could have expected.
Scientists create most powerful non-nuclear battery ever The chemical xenon difluoride is normally a mild-mannered white powder, but when you crush it with the pressure of 1 million times our atmosphere, it turns into a super substance. Due to some weird science, all the energy used to crush that stuff is stored inside its chemical bonds, making it a terrific energy storage device. In layman's terms, that would be a battery. Of course, it's not going to be easy to apply 1,000,000 atmospheres worth of pressure to this caustic and stinky powder that's normally used to etch circuits on silicon. To withstand that kind of pressure, you need a tiny 2-by-3-inch compartment lined with a couple of diamond anvils. The result? Either way, the scientists at Washington State's chemistry labs behind this discovery have a long way to go before this tech has a commercial application. Via iO9
Comparison | OrientDB Manual 1.7.8 This is a comparison page between GraphDB projects. To know more about the comparison of DocumentDBs look at this comparison. We want to keep it always updated with the new products and more features in the matrix. If any information about any product is not updated or wrong, please change it if you've the permissions or send an email to any contributors with the link of the source of the right information. The products below all support the TinkerPop Blueprints API at different level of compliance. The table below reports the time to complete the Blueprints Test Suite. So this table is just to give an idea about the performance of each implementation in every single module it supports. Lower means faster. All the tests are executed against the same HW/SW configuration: MacBook Pro (Retina) 2013 - 16 GB Ram - MacOSX 12.3.0 - SDD 7200rpm. To run the Blueprints Test Suite you need java6+, Apache Maven and Git. > git clone mvn clean install
blprnt.blg | Jer Thorp Quantum Levitation Will Blow Your Mind Let me preface this by dispelling any thought that you might have that I know anything about the quantum physics that makes all of this possible: I don’t know anything about the Quantum physics that makes this possible. But I do know something amazing when I see it. And this, my friends, kicks ass. This demonstration video, courtesy of the Tel-Aviv University and the Association of Science-Technology Centers (ASTC), has been making the viral rounds today. In saying that, I mean that I’ve seen dozens of social media shares of the video and it has been sitting on the front page of Reddit all day. The demonstration is in something called Quantum Levitation, a phenomenon that results from the fact that superconductors and magnets tend to not like each other. They start with a crystal “wafer” and coat it with a thin layer of a ceramic material called yttrium barium copper oxide. Superconductivity and magnetic field do not like each other. The term they keep using is “locked in space.”
