Graph Databases, published by O'Reilly Media Physics Flash Animations - StumbleUpon We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below.

Solid-state drive DDR SDRAM based SSD. Max 128 GB and 3072 MB/s. PCIe, DRAM and NAND-based SSD. As of 2010[update], most SSDs use NAND-based flash memory, which retains data without power. Hybrid drives or solid state hybrid drives (SSHD) combine the features of SSDs and HDDs in the same unit, containing a large hard disk drive and an SSD cache to improve performance of frequently accessed data.[9][10][11] Development and history[edit] Early SSDs using RAM and similar technology[edit] SSDs had origins in the 1950s with two similar technologies: magnetic core memory and card capacitor read-only store (CCROS).[12][13] These auxiliary memory units (as contemporaries called them) emerged during the era of vacuum-tube computers. Later, in the 1970s and 1980s, SSDs were implemented in semiconductor memory for early supercomputers of IBM, Amdahl and Cray;[15] however, the prohibitively high price of the built-to-order SSDs made them quite seldom used.

World's Smallest Hard Drive Built of Atoms Just 96 atoms make up one byte of magnetic storage space. - Scientists have built a magnetic storage device made of 96 atoms. - The advance could lead to tiny hard drives able to store 200 to 300 times more information than they can today. Hard drives could one day be the size of rice grains, powering music players so small they would fit inside your ear. Scientists at IBM and the German Center for Free-Electron Laser Science have built the world's smallest unit of magnetic storage, using just 96 atoms to create one byte of data. Conventional drives require a half a billion atoms for each byte. The advance could lead to tiny hard drives able to store 200 to 300 times more information than they can today. PHOTOS: 5 Computer Techs to Replace Silicon Chips "An effect that is common in nature can produce this information storage idea," said Sebastian Loth of CFEL, lead author of the research, which is being published today in the journal Science.

Home | OrientDB Document-Graph NoSQL DatabaseOrientDB Document-Graph NoSQL Database Fallacy List 1. FAULTY CAUSE: (post hoc ergo propter hoc) mistakes correlation or association for causation, by assuming that because one thing follows another it was caused by the other. example: A black cat crossed Babbs' path yesterday and, sure enough, she was involved in an automobile accident later that same afternoon. example: The introduction of sex education courses at the high school level has resulted in increased promiscuity among teens. A recent study revealed that the number of reported cases of STDs (sexually transmitted diseases) was significantly higher for high schools that offered courses in sex education than for high schools that did not. 2. example: Muffin must be rich or have rich parents, because she belongs to ZXQ, and ZXQ is the richest sorority on campus. example: I'd like to hire you, but you're an ex-felon and statistics show that 80% of ex-felons recidivate. 3. example: All of those movie stars are really rude. 4. 5. 6. 7. 8. 9. 10. 11. example: Only man is rational. 12.

iPads can’t improve learning without good teaching Pt 2 – Writing Used with permission from Debbie Ridpath Ohi at Inkygirl.com ( ) Writing and technology has been a controversial subject for many traditionalists in education. “Spell check stops children from learning to spell”. “All students do today is copy and paste from Wikipedia and Google searched articles.” ” Children need to handwrite all their drafts”. “William Shakespeare didn’t have a laptop” ( OK, i just threw that in for fun!) The key words in that last sentence are of course publishing and writing. Which leads me once more to the star of “Mr G Online”, the iPad. I’ll preface this discussion by saying that many of my suggestions can certainly be carried out on laptops or indeed desktop computers. What is writing? A breakdown of genres, their processes and products I’m not going to use some perfectly expressed term written by literacy professors to impress anyone. Now originally, communication was verbal. iPADS AND WRITING The Composing/Editing stage
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
