Big data's road of practice

Big data Spark is written in Scala, so studying Scala carefully is the first choice. Scala is a multi-paradigm programming language for object-oriented programming and functional programming, which is different from java and more powerful than java. Download "Programming in Scala", slowly gnaw, although authentic, but after all, the ability to understand English is limited, some very professional features explain is still a little knowledge, do not understand the main points, to refer to the Chinese version, so gnaw a paragraph and go back to see the corresponding Chinese version to deepen understanding, but the progress is very slow, very distressed, fortunately on 51CTO to see Wang Jialin all free "Scala deep introduction to the actual combat entry classic video"

Happy to look out, like a long drought and spring rain, such as a treasure, can not help but hate their own hindsight. Although I am very busy at work every day, I still find time to study. As long as I am free from work, I will watch the video of Mr. Wang on my mobile phone.

Found that what teacher Wang said is a combination of source code cases, easy to understand, practical and clear, such as the spring breeze, suddenly enlightened, the effect is N times better than reading, some difficulties are quickly digested and understood one by one, one footprint a day, after learning primary, calm down to think and sum up a day, and then continue the study of intermediate courses. From these studies, we can see that the new generation of high-level languages not only provide an unprecedented level of abstraction, but also provide us developers with more humane care. The combination of Functional Programming and OOP, super-powerful Pattern Matching, type parameters, type covariance (+ T and-T), function Curing, paradigm, more powerful closure, and so on. For example, the extremely flexible pattern match, the core is actually Companion Object (though not limited to this), implicit apply (build) and unapply (deconstruction) methods, while match can return various types of values, making the syntax of matching particularly concise and efficient. Teacher Wang, like a wise messenger, led me through big data's sleepless nights and enjoyed big data's excessive splendor. I benefited a lot and gained more and more. I felt hungry and thirsty. I really hated that time would not wait for me. I was full of more ardent expectations and incomparable longings for in-depth insight into big data's Spark.

Big data is the right way and is the key direction of future development. Big data's strategy has also been listed as a key strategic direction at the Fifth Plenary session of the 18th CPC Central Committee. China has just started in big data, but various new forces have emerged as a new force, with great momentum. The value is growing with each passing day. At present, big data is closely related to us. In big data's application field, big data analyzes user personality data and accurately recognizes customer characteristics through user behavior big data. It can effectively help enterprises to enhance the operating value of related businesses (such as precision marketing / user segmentation and marketing), such as the targeted promotion of Wechat, and the various products promoted by the browser are similar related products that you have browsed recently, and so on. HiHunting big data user portrait products help enterprises quickly apply big data insight into customers. no, no, no. It has generated hundreds of billions of market value abroad, such as Wal-Mart search. The retail oligarch designed the latest search engine Polaris for its website Walmart.com, which uses semantic data for text analysis, machine learning and synonym mining. According to Wal-Mart, the use of semantic search technology has increased the completion rate of online shopping by 10% to 15%. " For Wal-Mart, that means billions of dollars. American General Motors has installed sensors on every part of the aircraft engine. These sensors continuously transmit engine status data to GM's cloud platform while the aircraft engine is running. According to big data's analysis, you can keep track of the flight status of each airline engine at any time, and you can tell these airlines which parts of the engine need to be overhauled or maintained to avoid aircraft accidents. General Motors has generated tens of billions of dollars through this service. The Tesco PLC supermarket chain collects data on 7 million refrigerators in its data warehouse. Through the analysis of these data, more comprehensive monitoring and proactive maintenance to reduce the overall energy consumption, considerable annual savings. PredPol works with police in Los Angeles and Santa Cruz and a group of researchers to predict crime rates up to 500 square feet based on variants of earthquake prediction algorithms and crime data. In the area where the algorithm is used in Los Angeles, the distribution of larceny and violent crime has dropped by 33% and 21%, respectively, and the value of social property saved is immeasurable and far-reaching.

Now is the best opportunity to learn from big data. To truly enter the world of big data, teacher Wang Jialin is not only a big data preacher, but also like an oriental master, shouldering his 3000 disciples, laughing at big data excessively and trying to compete with the Duke of Heaven. Therefore, his videos and books can not be missed, as long as you persevere step by step, keep thinking and work hard, you can soon become a master of big data and realize your dream of an annual salary of 500000 yuan.

Wang Jialin's first Chinese Dream: train 1 million excellent big data practitioners for the whole society free of charge!

Through teacher Wang Jialin's WeChat account 18610086859, you can donate free practical courses such as big data, Internet +, O2O, Industrial 4.0, Micro Marketing, Mobile Internet and so on.
