supposed to continue training to prepare for next year's match, and I was unexpectedly recommended by my teacher to the new project called "Internet of Things applications and maintenance" I have so far lamented my luck how so good. Because I now have all the computer knowledge in this competition is almost learned. Just to this Contest day 1 weeks of time, this project teacher took me in the classroom to spend 1 years of learning VB in the form of C # re-taught again, and also learned how to b

Transferred from: http://www.jdon.com/bigdata/whatisbigdata.html----------You may ask what is big data, which is almost the latest trend in every business area? Is it just hype?In fact "big data" is a very simple term-it just says-a very large data set. How big is it? The exact answer is "as big as you can imagine"!Why is this data set so large? Because the data can come from ubiquitous, time-invariant: RFID sensors, traffic data, used to collect weat

The glusterfs allows users to get rid of their original, high-cost, closed storage systems and to deploy a centrally managed, scale-out, virtualized storage pool that can be scaled to the TB/PB level using inexpensive storage devices.Currently Glusterfs has been acquired by Redhat, its official websit

These days after a period of study, everyone began to embark on a hospital project on the hospital asset management system.But in the initial phase of demand analysis, there is a lot of trouble.The requirement that the user wants is a piece of content, and the actual operational way is another content.Users tend to idealize everything as much as possible, but there are many limiting factors, such as cost, software limitations, and so on.Take this inventory of assets, equipment section of the chi

) and velocity (velocity). Speed refers to data flow and very fast data, data accumulation or low latency when entering the data warehouse, so that people can make decisions more quickly (or even automatically). Data flow is really a big problem, but for me, the variability is the most interesting of the 3V.The icons shown above are the source of big data generation. In fact, this illustrates a philosophical problem-not just big data changes, but more, the definition of the data itself has chang

Adaptive learning usually refers to the learning environment, strength and field provided by learning, through the learner's own learning to find a summary, and ultimately to form a theo

JEDEC was established in 1958 as part of the Association of Electronic Industry Associations (EIA) to set standards for the emerging semiconductor industry. Key features include terminology definitions, product characterization, test methods, solid state memory, DRAM, flash memory cards, and RFID tags for identification and standardization.In the DDR2 era, the maximum operating frequency of JEDEC's DDR2 was 800MHz, but many module manufacturers introd
