overall idea. 3. Software Construction guide-how do we plan a system? We need a clear software build guide set. our system will be written and maintained by a programmer team-so it is important for all programmers and system designers to understand the system architecture and its potential philosophy. from a practical point of view, this knowledge is presented in the form of a software constructor guide for easier maintenance. A complete software constructor set includes a set of programming ru

Friends in the blog Park, this time they have another chance to let you know Erlang, a good language. Please keep up with me and buy an Erlang book, or download an ebook and start the Erlang world. This is a new journey. Let's take a look at mochiweb, a good HTTP server. The title is changed to the source code for reading, rather than the source code analysis. I

Erlang is a distributed development language based on message transmission. It is easy to develop and has powerful functions. Although Erlang's FP programming is nothing for some FP geeker, there is still a huge gap to be told by most developers at work, in addition, it is inferior to other "mainstream" languages in terms of convenience of development. What a wonderful situation would it be if we could graft the powerful capabilities of

supports libriaries) will be responsible for error logging and overload protection.Using Gen_server, gen_supervisor,application and other behaviors, you can build a system with a reliability of 99.9999999.Unified Erlang Message:1) Abstract the difference between different line protocols2) Erlang messages do not need to be parsed, the receiving process does not have to parse the message before processing, a

Keywords: Erlang, process pool, Open Source 1. Scenario There are many places in the project that connect to zookeeper. They are connected to each other, save the PID or monitor, and close or reconnect the connection when terminate or down. You can use the Erlang process pool to manage processes in a unified manner. Two scenarios that require process pools: 1. A large number of common

The Erlang version of the company development and test environment is 19.0.3,RABBITMQ version 3.6.10. Stable use for nearly a year under the cluster condition, no problem.In order to remain consistent with the line, the online production environment uses the same version, and after several months of operation the problem occurs. The phenomenon is as follows:In a few days, there were three queues with no consumer problems. View the logs for RABBITMQ.Op

Erlang distributed issues that should be paid attention to between linux and windows systems-Linux Enterprise Application-Linux server application information. The following is a detailed description. If nothing happens, test Erlang distribution between two machines. One is Windows XP, and the other is redHat9. Without detailed documents, you can find it and record it. 1. First, the implementation of dis

Rebar is a follow ERLANG/OTP principle Erlang Project builder, using it to reduce the build standard ERLANG/OTP Project architecture configuration, and can be easily compiled, tested, published Span style= "font-family:arial; Background-color:white; " > Erlang application. More powerful, rebar Provide

There are two common types of network communication: Text communication and binary communication. Text communication between php and erlang is relatively simple. We will not discuss it here. We will mainly discuss how php and erlang implement binary communication. Communication Example erlang code:-module (server).-export ([start0]).-define (UINT, 32unsigned-litt

The module is the Basic code unit of Erlang, and the Erl file is compiled with. Beam as the extension, with the UTF8 character set, and the. erl file as shown below:-module (module name, the same as the file name of the storage module)-export ([number of method name/input parameter])Method1 ({a,b,c})->a*b*c;MEHTOD2 ({d,e})->d-e.There are two types of module properties: predefined and user-defined.The data type used in

Erlang uses some common parameters and commands of hipe SASL Monitor, which are recorded in this memo. Compile and enable hipe (High Performance Erlang) What is hipe? The Overlord has a description in the phrase "Erlang's hipe is equivalent to JIT. According to the language evaluation, hipe supports 2-3 times faster in pure Erlang operations, this performance
