Wingide is a fairly good IDE; its editors include a large number of language syntax tags highlighted, although it is just a tool for Python. The source browser is very useful for browsing items or modules (tables are now navigable in source code and document line summaries). Although there are no monitors, the debugger is well designed. The editor has excellent command autocomplete and function jump lists, but no code merging. The project-oriented IDE is useful for large products (in this respect, it is in most free ides except Komodo ...).

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 ...

The Python framework for Hadoop is useful when you develop some EMR tasks. The Mrjob, Dumbo, and pydoop three development frameworks can operate on resilient MapReduce and help users avoid unnecessary and cumbersome Java development efforts. But when you need more access to Hadoop internals, consider Dumbo or pydoop.     This article comes from Tachtarget. .

The computer came into my life very early. However, I have always wandered as a layman: neither a computer education nor an IT industry. Think of yourself these years in the front of the door dangling, leaving and gathering, quite sentimental. The first time close contact with primary school, the family put a Lenovo "Qin" computer. Its domineering side leaky speaker, incomparable pull the wind microphone, mysterious remote control, all shook my heart. Then the little boy would spend an afternoon studying the difference between the left and right keys and the function of the "Start" menu. In junior high School, the game became synonymous with computers. I'm buying Volkswagen software at the newsstand ...

Introduction: It is well known that R is unparalleled in solving statistical problems. But R is slow at data speeds up to 2G, creating a solution that runs distributed algorithms in conjunction with Hadoop, but is there a team that uses solutions like python + Hadoop? R Such origins in the statistical computer package and Hadoop combination will not be a problem? The answer from the king of Frank: Because they do not understand the characteristics of R and Hadoop application scenarios, just ...

Original: http://www.kamang.net/node/223 The reader is impatient, I did not, so first say the conclusion: you can not edit the program, as long as the mouse to drag a few icons, change parameters, you can complete the distribution of billion data processing procedures. Of course, the ideal goal has not yet been achieved, but the road has been plainly displayed in front of us, at least we have come close to half. First of all, the MapReduce algorithm itself comes from functional programming, so using FP's idea to build the algorithm is again ...

After the ZOPE3 installation is complete, you can use it to do a lot of things. Of course, there are some interesting Third-party plug-in (add-on) packages, such as http://www.aliyun.com/zixun/aggregation/22.html > relational database adapters and wiki implementations. Wikis are made up of a large number of pages and can be edited by any group or person who accesses them. These pages are connected to each other through a wiki link that passes through the name of the other wiki page ...

In mailbox rapid expansion process, one of the performance problems is the MongoDB database level write lock, the time spent in the lock waiting process, directly reflects the user's use of the service process delay. To address this long-standing problem, we decided to migrate a common set of MongoDB (storing mail-related data) to a separate cluster. According to our inference, this will reduce the lock latency by 50%, and we can add more fragments, and we expect to be able to optimize and manage different types of data independently. We start from Mon ...
