　　我是清华软院22班的王程鹏。在本次Popush开发过程中，负责承担在Popush中添加Haskell文件选项，并且保证其可以正常运行。当初接到这个任务时，觉得有点像天方夜谭，远远超过了个人的能力。在后来的开发过程中，有了李映辉同学的帮助，同时也可以和其他组的同学沟通，这些都为我们任务的完成提供了积极有利的因素。 　 这次优化开发，第一个难点在于如何正确配置好Popush。某天下午刘博格同学开始配Popush，很高效率地在三、四个小时之后配好了Popush。彭友在Linux下也配好了Popush。他们配置工作的顺利进行为我们的工作的开展打下基础。 在Popush网站上注册后登陆，发现其支持多种语言，可以在连接好外接编译器后，将Popush中的代码放入外接编译器中编译运行。开始时，我们发现了只要安装好对应语言的编译器，并将编译器的路劲放进系统的环境变量中，便可以在Popush平台中运行代码。这点启发了我和同伴。刚开始时我尝试在前端看一些图片或者分析一些相应，但最都没有头绪。上面的启示说明：不

this short code that implements the lazy semantics of Haskell). Several common styles of languageLet me briefly describe some of the common language styles and their problems.1. Object-oriented languageIt turns out that the whole concept of "object-oriented" is fundamentally wrong. Its popularity is due to the original "Software crisis" (God knows if there is a real crisis). The design is designed to separate the "interface" and "implementation" so t

Well, are you ready to learn a new programming language now? You may not have contacted this field before, and you are welcome to the new world of application development. Or you've been in the field of application development for years, but you want to start a new field. Choosing a programming language is not a very good job to do. Here is a step (see the original image, see the larger picture) There are 15 programming languages mentioned here: C#,java,objective C,ruby,python,groovy,clojure,sc

A type is an important part of understanding the programming language. Even if you like dynamic type language, you must understand the type in order to achieve something that is reliable. As a simple example, we all know that + and-are symmetrical-and of course that's just our wish, and in JavaScript, "1" +2 and "1"-2 is not the same thing. This is some of the funniest mistakes that have been made by not knowing the type of operation. What, you think because the type of "1" is string, so "1" +2

write articles on Go and to organize conferences and meetups. They is so rich, which next year Go community would have 6 international conferences including one in dubai! When D has a company so can do the same for D and the world would understand that Go's popularity is a fake. Also, Go is not a real system programming language. You can ' t write your own memory allocator with Go. So switch to D. ... Perl EMM: ... C# Probably the best strategy here's to attack the simplicity of Go. Simplicity

rationality and claims that experience filtered by transcendental rationality leads to truth. When his philosophy matured, he began to study aesthetics, and tried to explain the aesthetics of human being theoretically. Kant's extremely precise character, obsessed with cleanliness and precision, fixed things at a fixed time every day, so that his acquaintances could "use" them for timekeeping.In the same vein, Python is a new programming language that tries to combine various solutions. It is a

In Haskell, multiple parameter functions are implemented through colialization. It is written by Haskell Brooks Curry, and is the name of Curring (but not invented by him ).

1. Why Learning functional programming? To improve yourself, learn functional programming 2. What language should I learn? Select one that meets your needs. I think, if you are a very experienced programmer, the best answer to this question is: choose one that meets your needs. If you need to work on JVM, select Scala or clojure. If you want to quickly develop a large distributed software system, select Erlang. Select Haskell or r

programming language related to artificial intelligence and computational linguistics. The origin of the Prolog is the first-order logic-a formal logic, and unlike many other programming languages, the Prolog is declarative. Program logic is expressed in relation to facts and rules. Start the calculation by running a query on these relationships. 6.Haskell Haskell is a standardized, general-purpose, pure f

have used Java or a functional language (Haskell or ML), you might understand some type theory (type theory). In type theory, the type of data is diverse, Integer, String, Boolean, List, record ... The so-called "data" that passes between programs is just these types of data structures. However, according to the Unix design, all types have to be converted into strings and passed between programs. This poses a problem: Because the unstructured String

functional programming now that we have a precise and natural command-type programming? Let's give a small example.int fab (int n) {return n = = 1 | | n = = 2? 1:fab (n-1) + fab (n-2);}This is the program written in C that asks for the nth item of the Fibonacci sequence, and the corresponding Haskell code is this:Fab:: (Num a) = aFab n = if n = = 1 | | n = = 2 then 1 else fab (n-1) + fab (n-2)Looks pretty much right? But the two programs have a diffe

handful of Daniel can master it. So why not introduce ARC to the bottom to simplify development? I think this is another direction for Swift development. 21. It is said that Swift is a hodgepodge, part of the reference C #, part of the reference to Javascript, part of the reference objective-c, what do you think? Swift is indeed a hodgepodge. But it is not simply imitating other languages, but learning from them, and then creating a great language. We did refer to a lot of other language design

The convenience of functional programming is impressive in the map of Haskell.
