The resume interface will be designed for system construction, so that he can be connected to the resume System of applications in different languages. This is called the interface technology of Erlang. Three methods of interface technology: 1. allow external operating systems to run outside the Erlang virtual machine. This is a safe approach. The code in the real-time external language is also problematic

. During the test, I thought of the Erlang built-in ets and the legendary concurrency performance. If I use Erlang + ets as a key-value cache server like memcached, will the performance be better than memcached? As a result, I started my experiment and used Erlang to write a Socket server that supports concurrent connections and write a PHP client. In the test re

When analyzing Erlang:send's Bif, a Bif_trap series of macros was found. Refer to some of Erlang's own descriptions, which are designed to implement a mechanism called trap. The trap mechanism introduces Erlang's code directly into ERTs, allowing the C function to "use" these Erlang functions directly.Let's first think about why Erlang implements the trap mechanism. Let me start with the more recent fire go

Recently, Erlang version changed to R17, in order to support the Chinese language, the first line of the project all module file added the file format declaration: Percent coding:latin-1. However, Erlide will recognize this statement, causing the Chinese display garbled, this temporarily no option to solve the problem. So, I switched to the new IDE, which is the IntelliJ idea that this article is going to cover, which is good for

As projects become more dependent on Erlang, the problems they encounter increase. The system encountered high memory consumption problem in the previous time line, and recorded the analysis process of troubleshooting. The online system uses the Erlang R16B02 version.Problem descriptionThere are several online systems that run for some time and the memory soars. The system model is simple and has a network

Compile and install Erlang R16B02 in Ubuntu 12.04 LTS 64-bit. 1. Download the Erlang R16B02 source code package Http://www.erlang.org/download/otp_src_R16B02.tar.gz 2. Because java is needed in the process of compiling Erlang, so install JDK and configure the corresponding environment variables first, use the jdk-6u43-linux-x64.bin Export JAVA_HOME =/usr/local/jd

1) Design The implementation of Erlang is based on the virtual machine beam. Go is a compilation language and has a single-integrated Compiler (unlike GCC, go solves the dependency problem very well, therefore, when compiling the go program, you do not need to specify the include and Library as the C program.) tnsdl is similar to go and belongs to native execution. Erlang mainly serves telecom-level applica

The last time I talked about the basic idea and idea of implementing a simple cache, http://www.cnblogs.com/--00/p/erlang_ets_something_about_cache.html at the end of the article, speaking of judging single Record memory consumption. This time, we will continue to talk about Erlang data item memory related issues.In the Erlang efficiency_guide documentation, the memory consumption of the different data type

Number type, two points to note1) B#val represents the number Val stored in B-binary, such as7> 2#101.5101 of binary storage is 10 binary 5.2) $Char The ASCII encoding that represents char, for example, $ A = 652. More difficult to translate the concept of--atom, can be understood as a constant, it can contain any character, start with a lowercase letter, if not start with a lowercase letter or a

Erlang processes communicate from different perspectives, and Ralph says: even if the concurrency Erlan style can be easily added to other languages, these languages are hard to compete. Because Erlang is built specifically for telecommunications systems, all these aspects are important, and Ericsson has built an Erlang system with 99.9999999% normal operation ti

be no javac, I found online method is:sudo apt-get install openjdk-6-jdk The environment variables for the OTP-17 version of Erlang do not seem to be set:Then we enter in the terminal: Erl Enter, we enter the Erlang environment. It is now possible to start Erlang development.But wouldn't it be more convenient if we could have a good development IDE? After s

Overview It indicates that Erlang is a dynamic language and variables are dynamically bound at runtime, which is difficult for us to obtain the type information of function parameters and returned values. In Erlang, we can use type and spec to define the data type and function prototype. Through this information, we conduct static checks on functions and calls to find some problems in code. At the same time

It has been a while since Erlang was updated to R17. The company's projects planned to migrate from the old version of Erlang to R17, but there were a lot of troubles, one of which was a Chinese problem. This problem is easy to reproduce: Create a new file T. erl and save it as UTF-8 without BOM format. -Module (T).-Export ([test/0]). Test ()-> ["I", In the old Erlang
