Privately, it is only by understanding the origins of the era of big data that we can put our position in the tide of times.

Two years ago, we were discussing "what software should be used for statistical analysis". There were many options at the time, Spss,sas,r,python,excel,eviews,stata,c++,java ... The number is not counte
ASP. NET 2.0 provides some new improvementsProgramThe caching technology is a very important feature. It provides a very good local data cache mechanism to effectively improve the performance of data access.
Data caching is a technology used to store data in the memory cache (sometimes stored in the hard disk cache. when the data itself is not frequently changed and accessed frequently, using this technology will greatly improve the efficiency of data access.

(scientific computing) community. Since entering the 21st century, the use of Python for scientific computing in industry applications and academic research is gaining momentum.Python will inevitably be close to other open source and commercial domain-specific programming languages/tools such as R, MATLAB, SAS, Stata, etc. for data analysis and interaction, exploratory computing, and data visualization. In recent years, Python has a constantly improv
partition tool in linux with the same principle, but the tool format is different. One is the partition when the system is installed, and the other is the partition after the system is installed.The partitions during system installation cannot be modified or adjusted after the system is installed. Hard Disk Space Not partitioned during system installation can be operated or loaded by partitions after the system is installed.Here we mainly talk about this situation. One is to operate unpartition

In linux, fdisk is a hard disk partition tool with the same principle, but the tool format is different. One is the partition when the system is installed, one is the partition used when the system is installed in the partition. After the system is installed, it cannot be modified or adjusted. When the system is installed, the hard disk space is not partitioned, after installing the system, you can perform operations or partition loading. Here, we mainly talk about this situation. One is to perf

deep learning, is inherently unable to leave Python support, and the world's best AI learning framework, such as Google's Ransorflow, Facebook's Pytorch and the open source community's neural network library Karas are implemented in Python, and even Microsoft's CNTK (Cognitive toolkit) fully supports Python, and Microsoft's Vscode has supported Python as a first-level language.(3) Big data. Python's biggest feature relative to other explanatory languages is its vast and active scientific comput
Introductory Remarks:
In the areas of data analysis and interaction, exploratory computing, and data visualization, Python will inevitably approach other open-source and business-specific programming languages/tools, such as R, MATLAB, SAS, Stata, and so on. In recent years, Python has a constantly improved library (mainly pandas), making it a major alternative to data processing tasks. Combined with its power in general programming, we can only use

Why python for data analysis?
In terms of data analysis and interaction, exploratory computing, and data visualization, Python will inevitably be close to other open-source and commercial programming languages/tools, such as R, MATLAB, SAS, and Stata. In recent years, Python has continuously improved libraries (mainly pandas), maki
