. In fact, most of the Python implementations that we'll see in this article are more than just platforms in themselves. The concept of implementation is also different from the concept of version. As far as language features are concerned, all the implementations discussed here are essentially in the same language version (1.5.2). Obviously, CPython 1.6/2.0/3000 already has a part of the new basic implementation, but other implementations can be consistent with those language-level features. W

that are weaker from the user's perspective. Don't believe me? Ask your accountant what the idea of the new browser-based accounting software is: The vast majority of business program users want to use a more user-friendly Windows UI. A perfect solution to the client-server communication problem is to use the HTTP protocol to communicate. This is because any machine running a Web browser is using the HTTP protocol. At the same time, many firewalls are currently configured to allow only HTTP con

configured to only allow HTTP connections. Many commercial applications face another problem: interoperability with other programs. If all applications are written in the COM or. NET language and run on the Windows platform, the world is too peaceful. However, in fact, most commercial data is still stored on large hosts in the form of non-relational files (VSAM) and accessed by mainframe programs written in the COBOL language. In addition, there are

However, in fact, most commercial data is still stored on large hosts in the form of non-relational files (VSAM) and accessed by mainframe programs written in the COBOL language. Moreover, many commercial programs are still being written in C ++, Java, Visual Basic, and other languages. Now, except for the simplest program, all applications need to be

computer schedules the cards according to certain rules and executes them in a certain order of priority. This is the concept of interruption and task scheduling, the earliest operating system appeared like this. A company like a bank or an accounting firm puts the cards written every week in a computer to process a large amount of data. At this time, the computer is still a very complex equipment, and maintenance and use are very difficult. At that time, the computer production company must pr

to win back the market. So don't say that Microsoft is finished. In early 1990sSome people think that IBM will be a complete failure, because the mainframe has become history! Robert X.Cringely once said that the mainframe era will end in the millennium, because all mainframe applications developed using COBOL will expire due to the millennium bug and these applicationsSoftware source code has long been lost, and people can only re-develop these appl

COBOL. He said: "Java is no longer so easy to access ." For projects like building a front-end web for a database application, he thinks Ruby will be a good choice. He said: "with Ruby, you are not fast and messy, but fast and neat. The ruby programming language is indeed a very Successful ." He told many Java programmers: "Ruby's strength lies in its object-oriented nature, which is neat and adaptable ." However, when introducing Ruby's history

In fact, however, most commercial data is still stored in a VSAM file on a large host, and is accessed by a mainframe program written in the COBOL language. Also, there are many business programs that continue to be written in C + +, Java, Visual Basic, and a wide variety o

1- We use C #, VB. NET language will eventually be compiled into an assembly or IL. Therefore, code written with vb.net can be modified in C # and later used in COBOL. Therefore, it is very necessary to understand IL. Once you are familiar with IL, there is no barrier to understanding. NET technology because all of the. NET languages are compiled to IL. Il is a neutral language. Il was first invented, fol

about these large ERP software systems in the future, we should not hesitate to seize the Kim Yong.In foreign countries, people who are sap are particularly valuable. It is always the truth of irrefutable to dilute things. The value of SAP is not only because he is an ERP software, but the modern enterprise management concept embodied in it (such as automatically arranging raw material purchase and production plan according to order demand). The general 500 companies will never be like many ent

Back to Cloud Island: All SaaS users are happy. Because they can get a quick response. Because the only control that these users have is control over access to the application, they do not worry about whether the application has a multithreaded routine or how many cores in the cloud are used to accelerate multithreading in parallel. The problem application was successfully migrated from the internal multithreaded COBOL legacy system. Of course, one d

characters or phrases. Statistical models can be used to generate code for specific characters or phrases. Based on the frequency of their appearance, you can configure the shortest code for the most commonly used data. These technologies include entropy encoding, run-length encoding, and dictionary compression. Using these technologies and other technologies, an 8-bit character or string can be expressed with a small number of BITs, removing a large amount of repeated data.History It was not

, there is no reason not to allow these new applications to make full use of MDMS.In the second case, planning and budgeting can be linked as part of the system upgrade procedure. Of course, to add connections from these systems to the MDMS system, you need to perform a lot of analysis on the impact of such connections. For example, if you want to upgrade a data item stored in the MDMS, so what is the impact on the system? In addition, in such projects, funds are generally used for new features

computer languages are better than others. The following describes the main programming languages used to compile games and their advantages and disadvantages. I hope this article will help you make a decision.1. C LanguageIf FORTRAN and COBOL are the first generation of advanced compilation languages, C languages are their grandchildren. C language was created by Dennis Ritchie in 1970s. It is more powerful and maintains more continuous inheritance
