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

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

Nothing to do, just between two machines test Erlang distributed example, a station is WindowsXP, a set of REDHAT9, no detailed documents, their own groping for success, recorded.1. First, the implementation of distributed Erlang provides its own security mechanism to prevent unauthorized access to the Erlang system. When an
projects are in the same C # language, both Class Library organization and naming rules have their own rules and styles. 4. pre-defined parts-designing with a "select from a set of pre-defined parts" is far easier than designing from scratch. the OTP library of Erlang contains a complete set of ready-to-use parts (called behaviour Library), which can be used by some common systems. for example, behaviour such as gen_server can be used to build a clie
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

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

The zebra puzzle is a typical constraint satisfaction problem (CSPs). Sudoku, Magic Square also belongs to CSPs problem. The language features of Erlang's list parsing allow it to solve such problems in a way that is very close to the natural language: it does not need to consider the process-solving steps to describe the constraints, and the Erlang interpreter matches the answer through a domain search.
