OTP cognitionDynamic password (otp,one-time Password), also known as a one-time password, is the use of cryptography technology in the client and the server through the sharing of a secret authentication technology, is a strong authentication technology, is to enhance the current static password authentication of a very convenient technical means, is an important two-factor authentication technology, Dynami
OTP includes a set of libraries and implementations that can build large-scale, fault-tolerant, and distributed applications, including many powerful tools to implement multiple protocols such as H248,SNMP, the core concept is OTP behavior, and can be seen as an application framework with callback functions as parameters, similar to a Java-EE container. Behavior is responsible for solving the non functional
Http://blog.sina.com.cn/s/blog_3fe961ae0101k4p6.htmlBehavior patterns are very similar to interfaces in object-oriented languages, at least as I understand them. The OTP behavior pattern divides some recurring patterns into two parts, the generic part and the implementation-specific part of the application, which is similar to the process of abstracting out an interface in object-oriented programming. This article gives an example of the most common b

The dynamic password (OTP, one-time password), also known as the one-time password, is an authentication technology that uses the Password Technology to share secrets between clients and servers, it is a strong authentication technology, a very convenient technical means to enhance the current static password authentication, and an important two-factor authentication technology, the dynamic password authentication technology consists of a client used
To prevent parameters from being too long on the command line, or to play some advanced configuration, you can use the Inets configuration file, which already has an example of various configuration files for the OTP project:[Email protected] ~]# CD otp_src_17.5/lib/inets/[[email protected] inets]# find.-type F-name *. config./test/Inets.config./src/inets_app/Inets.config[[email protected] inets]# find.-type F-name *. conf./examples/server_root/conf/8

Previously, the following paper was mentioned in the Erlang paper we have read in [Erlang 0126:On preserving term sharing in the Erlang Virtual MachineAddress: http://user.it.uu.se /~ Kostis/papers/erlang12_sharing.pdfAbstract: In this paper we describe our experiences and argue through examples why? Attening terms during copying is not a good ideaA language like Erlang. More importantly, we propose a sharing preserving copying mechanic for Erlang/
NetScaler OTP Application ScenarioNetScaler OTP (one time password) is a two-factor ID card that uses the username password + 6-bit token authentication code to complete the identity authentication. In the previous two-factor solution, Netscalergateway needed to be integrated with a third-party RADIUS server for two-factor authentication. For customers, the cost of additional two factor authentication is re

This function is very simple, just a line of logic, calling the system function:Proc_lib: spawn_link/3, Erlang Doc address: http://www.erlang.org/doc/man/proc_lib.html?spawn_link-3,e. g:
This function is similar to the spawn_link function in the Erlang module. It initializes a process to execute the specified function in the specified module. What are the differences between processes created using proc_lib? I am not going to talk about it here. For details, refer to the article [Erlang 200

Why does it trigger data expansion (expand, flattening? See the following code. When the shell is started, the variable that has been bound previously will be used as the spawn_link parameter to start the new shell.

Erlang/OTP organizes a group of modules that complete specific functions, called applications. This is not a good name. It has different meanings from the conventional application. For example, in the development of Jee, the entire application system is called an application; in iOS, an independent game and a small tool are called an application.The Application of Erlang/
