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? EnterpriseDB Save money provisioning Postgres clusters Postgres Plus Cloud Database provisions cloud based elastic PostgreSQL and Postgres Plus Advanced Server databases (with Oracle compatibility) in single instances and read scalable clusters. The clusters are set up in minutes with high-speed binary replication, automatic read load balancing, optimized connection pooling, auto-scaling (for horizontal read scale out and storage), scheduled backups, and automatic failover.
Connecting Batteries in Series or Parallel We frequently get asked the question, "How am I supposed to connect my battery if I want to double the capacity but not the voltage?", or similar questions. It can be confusing if you've never done it, but hopefully this'll make it simpler. 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. SimpleDB Amazon SimpleDB is a highly available NoSQL data store that offloads the work of database administration. Developers simply store and query data items via web services requests and Amazon SimpleDB does the rest. Unbound by the strict requirements of a relational database, Amazon SimpleDB is optimized to provide high availability and flexibility, with little or no administrative burden. Behind the scenes, Amazon SimpleDB creates and manages multiple geographically distributed replicas of your data automatically to enable high availability and data durability. The service charges you only for the resources actually consumed in storing your data and serving your requests.
How to Make Toy Air Ships, Ray Guns and Much More from Old Tin Cans Photos Courtesy of Tinplate Girl If you try to live sustainably, chances are you recycle the tin cans that once fed you soup or mints. But there are lots of good reasons not to, and the alternative is upcycling them yourself. We've featured lots of DIY projects making cool things out of old tins, and now a new web site dedicated to giving you a lot more has been launched. Transistors made from cotton yarn, t-shirt computers incoming Altering the very fabric of technophilic society, a multinational team of material scientists have created electric circuits and transistors out of cotton fibers. Two kinds of transistor were created: a field-effect transistor (FET), much like the transistors found in your computer’s CPU; and an electrochemical transistor, which is similar but capable of switching at lower voltages, and thus better suited for wearable computers. If you’re like me, you’re probably thinking that cotton is a very strong insulator and not at all conducive to conductiveness — but before you accuse this team from Italy, France, and the United States of witchcraft and wizardry, bear in mind that they kind of cheated. Cotton is just the substrate: To make it conductive, the researchers coated cotton threads in a variety of other materials. To make conductive “wires,” the team coated the threads with gold nanoparticles, and then a conductive polymer.
Soon you'll 'evolve' yourself new furniture using 3D printing Most of the time, when you buy something, you end up getting someone else's idea of what you really want. With custom 3D printing becoming cheaper and more available, the options for customization are endless, and a new service could allow the "evolution" of new products that are perfect for you. Evolution, at its most basic, is the idea that good and useful things will tend to be favored in designs over things that are not quite so good and useful. You can see it all over the place in animals, but it's equally true in products: version 2.0 of your computer or car or sunglasses or furniture takes everything that was good about version 1.0 and makes it better, while mixing in a bunch of new stuff at the same time. Or at least, that's the idea. But why should you have to suffer through version 1.0 to get to version 2.0?
Want To Make A Giant Telescope Mirror? Here's How hide captionTemperatures inside this giant oven will reach 2,100 degrees Fahrenheit. Large blocks of glass inside the oven will melt as the whole oven spins around at a rate of five times per second, creating a curved and smooth telescope mirror. Ray Bertram/Steward Observatory Temperatures inside this giant oven will reach 2,100 degrees Fahrenheit.
Repurposed Etched Glass Spice Jars... As an avid recycler, I often find myself admiring the numerous boxes of glass bottles in our garage, awaiting their fate. When I noticed more than a dozen empty bottles from one particular product, I knew I had a problem there must be something else I could do other than toss them into a recycling bin once a week. In order to justify my purchase of a caffeine-laden treat, I decided to repurpose and upcycle the glass containers from my favorite splurge. Enter Starbucks Frappuccino. (I know, I know, but I'm trying...)
iModela, Roland's $1000 hobbyist CNC milling machine We've covered the iModela, Roland's $1000 hobbyist CNC milling machine over at MAKE, but here's a new photo showing some of the things you can make with it. A milling machine is sort of the opposite of a 3D printer, because it carves away material from a piece of stock, while a 3D printer adds material. I think home-based 3D printing is not yet ready for prime time, because the spatial resolution of the things you can make with 3D printers is not that great. It will get better in the coming years. But the output from this milling machine looks great (as far as I can tell from the photos). [Video Link]
