Core Java Skills Set

Last year in the investigation of a lot of java applications, see some of the phenomenon is the programmer to run on their own environment to read the program rarely lead to troubleshooting problems will be more frustrating, so think of writing this series of articles, procedures To provide functionality to end-users, the code is only one part of it, and it needs to be relied on for jvm, os, server hardware, networking, load balancing, etc. In this series of articles, Several parts, more is only a science role, because os I use are linux, this series ...

In the 8 years of Hadoop development, we've seen a "wave of usage"-generations of users using Hadoop at the same time and in a similar environment. Every user who uses Hadoop in data processing faces a similar challenge, either forced to work together or simply isolated in order to get everything working. Then we'll talk about these customers and see how different they are. No. 0 Generation-fire This is the beginning: On the basis of Google's 2000-year research paper, some believers have laid the commercialization of cheap storage and computing power ...

With the upsurge of large data, there are flood-like information in almost every field, and it is far from satisfying to do data processing in the face of thousands of users ' browsing records and recording behavior data. But if only some of the operational software to analyze, but not how to use logical data analysis, it is also a simple data processing. Rather than being able to go deep into the core of the planning strategy. Of course, basic skills is the most important link, want to become data scientists, for these procedures you should have some understanding: ...

This is the second of the Hadoop Best Practice series, and the last one is "10 best practices for Hadoop administrators." Mapruduce development is slightly more complicated for most programmers, and running a wordcount (the Hello Word program in Hadoop) is not only familiar with the Mapruduce model, but also the Linux commands (though there are Cygwin, But it's still a hassle to run mapruduce under windows ...

The outlet of the specialty of e-commerce where a senior practitioner to the E-commerce Professional school, teachers, students of a letter this letter Hui Jian wrote almost one weeks, modified a lot of times, because Hui Jian saw a few students majoring in E-commerce to become a porter, is really not see the kind of helpless eyes. The parents worked hard to save money, read four years of university, came out but can only go to chores. 　　Why? 　　Here is the reflection of Hui Jian. One, the social demand many and the embarrassment of e-commerce graduates two, society ...

There are a few things to explain about prismatic first. Their entrepreneurial team is small, consisting of just 4 computer scientists, three of them young Stanford and Dr. Berkeley. They are using wisdom to solve the problem of information overload, but these PhDs also act as programmers: developing Web sites, iOS programs, large data, and background programs for machine learning needs. The bright spot of the prismatic system architecture is to solve the problem of social media streaming in real time with machine learning. Because of the trade secret reason, he did not disclose their machine ...
