Detailed analysis of sample codes for performance comparison of golang, python, php, c++, c, java, and Nodejs
This article mainly introduces relevant information on the performance comparison of golang, python, php, c++, c, java, and Nodejs. Friends in need can refer to it When I was working in PHP/C++/Go/Py, I suddenly encountered I had an idea and wanted to make a simple comparison of the performance of the recent mainstream programming languages. As for how to compare, I still have to use the magical Fibonacci algorithm. Maybe it’s more commonly used or fun. Okay, talk is cheap, show me your code! Open your Mac, click on Clion and start coding! 1. Why is Go the first one? Because I am using it personally recently and I feel very good. package main import “fmt” func main(){ fmt.Println(fibonacci(34)) } func fibonacci(i int) int{ if(i<2){ return i; } return fibonacci(i-2) + fibonacci(i-1); } Let’s take a look with Go1.7 first: The code is as follows: qiangjian@ localhost:/works/learnCPP$ go version && time go build fib.go && time ./fibgo version go1.7.5 darwin/amd64 real 0m0.206suser 0m0.165ssys 0m0.059s real 0m0.052suser 0m0.045ssys 0m0.004s Then, look at 1.8: The code is as follows: qiangjian@localhost:/works/learnCPP$ go18 version && time go18 build fib.go && time ./fibgo version go1.8 darwin/amd64 real 0m0.204suser 0m0.153ssys 0m0.062s real 0m0.051suser 0m0.045ssys 0m0.003s I…

What is ThriftThrift is a scalable cross-language service development software framework. It combines a powerful software stack with a code generation engine to build services. Thrift was developed by Facebook. It opened source code in April 2007 and entered the Apache incubator in May 2008. Thrift was created to solve the problem of large data transmission and communication between systems in the Facebook system and the need for cross-platform features due to different language environments between systems. Therefore, thrift can support a variety of programming languages, such as: C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, Javascript, Node.js, Smalltalk, and OCaml. (The current version 0.9.1 has started Supports golang language) to communicate between multiple different languages. Thrift can be…

An article to help you understand the analysis of parameter passing principles (java, go, python, c++)
Foreword In the past year or so, I have been exposed to some languages that are unfamiliar to me, mainly Python and Go. During this period, in order to quickly realize the needs, I just followed the example. Lao’s code; I didn’t delve into some details and principles. Take parameter passing as an example. The implementation details of each language are different, but there are similarities; it is easy for many novices to be confused when they get started, leading to some low-level mistakes. Java Basic type transfer Let’s take Java, which I am most familiar with, as an example. I believe no one can write such code: @Test public void testBasic() { int a = 10; modifyBasic(a); System.out.println(String.format(“Final result main a==%s”, a)); } private void modifyBasic(int aa) { System.out.println(String.format(“aa==%s”, aa)); aa = 20; System.out.println(String.format(“After modification aa==%s”, aa)); } Output results: Before modification aa==10 After modification aa==20 Final result main a==10 However, judging from the purpose of this code, it should be to modify the value of a. Intuitively, it is understandable if the modification is successful. The fundamental reason why the results are not in line with expectations is the misunderstanding of parameter value passing and reference passing. Before…
Why do many companies turn to Golang? Are Java, Python, and C# declining?
Go language is the second open source programming language released by Google in 2009. The Go language is specially optimized for programming multi-processor system applications. Programs compiled using Go can be as fast as C or C++ code, are more secure, and support parallel processes. Why do many companies turn to Golang? Are Java, Python, and C# in decline? golang logo When choosing a development language for a project, focus on performance, improvement of the language technology stack, development efficiency, and language learning costs. Choose golang for many reasons How is the performance: Golang’s performance is relatively high, and qps, which does not require a framework to write an API, can be comparable to nginx. This kind of performance is unmatched by python. Language technology stack: Golang’s development technology stack is also very complete, and all required common components can be found on github. Development efficiency: Some coders who love C/C++ know that C/C++ development efficiency is not high, and go can solve the problem of development efficiency. A senior engineer said that he has been developing system software in C language for more than ten years. Now I will use go wherever Go can be used (except for the…

gopythonjavascala_[Transfer] Comparison of R, Python, Java, and Scala Go Language Chinese Community
Data Science，An exciting field just thinking about it，combines the most beautiful statistical knowledge with programming ability through different wisdom，a 1+1>2 field，and all the developments this year indicate that the glorious day of data science has arrived，whether it is big data,artificial intelligence,deep learning or data analysis， All are inseparable from data science. Data science is widely used in various fields，All programming languages are also accepting data science，So what is the best data science？ Although there is no absolute Answer，But there are a few things to consider，After all, becoming a data scientist depends on many aspects： 1. Applicability In In data science we talked about, “if you want to go further”, it’s obviously not feasible to reinvent the wheel every time. It is necessary to learn and master the various software packages and tools provided in the chosen language – and a language with broad applicability and many packages will be a good choice. 2. Speed In the often fast-paced world of commercial data science ， it is necessary to complete a job quickly，therefore， The speed of technology is taken into consideration – not only the speed of operation – but also the speed of learning. 3. Performance In some cases, it…
Python, Django or RoR, that is the question

Pythonits own advantages and friendlinessURL , convenienttemplate, MVC, all It makes writingDjangosmooth|good mood s reason. But further down, I am still a little worried. One is Ajax, looking for a circle, that is “ Ajax With Django” The resources given in this article are reliable; the second is the issue of future upgrades. Regarding the integration of Ajax and Django, should you choose to integrate Dojo, integrate JQuery, or use MochiKit directly like TurboGears? November 3rd, haha, James Bennett’s answer is cool: “ On 11/3/06, Enquest wrote:> What would it take to integrate jquery to Django?> Just like now is happening with Dojo… I think however jquery is a> better lib … Dojo integration was a fleeting, now-discarded idea. Django will notbe “integrating” any JS toolkit. One good reason for this is evidentin your post: no matter which one was chosen, someone would always be thinking that some other toolkit would have been better.” Yes, there will always be people who are dissatisfied. but. . . They have always followed this principle “make the simple things easy and the…

Graph DijkstraAlgorithm selects shortest path in planar grid node graph in 2D space, networkx, Python
Graph Dijkstra Algorithm selects the shortest path in the 2D space plane grid node graph, networkx, Python (1) After the Dijkstra Algorithm algorithm is completed, the two-dimensional code generated The weight of all nodes in the grid graph is the shortest path from the starting point (source point) to the current node. In this example, the weight of all adjacent edges in the grid graph is 1. (2) Iteratively search all the way up through the parent pointer saved in each node, until you reach the starting point (source point), which is the shortest path from the starting point to the current node. The parent pointer points to the shortest path parent node to the current node. (3) After the Dijkstra Algorithm pathfinding is completed, the shortest distance from the starting point (source point) to all reachable points is determined (the weight value is the shortest path value). You can get inspiration from it. For example, in a multiplayer battle game, multiple people on a map need to know the path to a certain convergence point at the same time. Then the Dijkstra Algorithm is very suitable for this algorithm application scenario (on the contrary, the Aalgorithm is very suitable…
