erlang

Went to Fuzhou, things did not fix, entrusted to the students to help deal with, home rest two days to work. Home these days the biggest harvest is the fourth time to reread the "deep Java Virtual Machine", previously unclear chapters enlightened, a sense of enlightened feeling, it seems, the technology of learning or anxious not to come.Gossip does not mention, continue the study of Erlang, last learned the chapter of distributed programming, the rem

Transferred from: http://www.thinksaas.cn/group/topic/244329/Feature Description: There is insufficient encoding support for various languages in Erlang, which uses Erlang to drive the well-known Iconv encoding library to encode and convert characters. File Description: Iconv_erl.c and iconv.h are the driver of the Erlang character encoding module, which is the f

1. Erl-detached This document describes the applicability of daemons and background programs. It also applies when node is dynamically pulled in the Code. Otherwise, the problem of terminate Erlang will be reported. 2 init stop Can terminate the VM, combined with RPC: Call can end the specified Node 3. control common test in code CT: Install specifies the config file, CT: start_interactive (). This is very important. It specifies the interaction mode.

As mentioned above, the smerl in erlyweb already has a ruby-like tuples for programming. This article will introduce the basic principle of implementing tuples for programming. In smerl, the abstract form of Erlang is mainly used for implementation. We will examine the composition of Erlang abstract form in detail. The method is very simple. Refer to the abstract form section in the eralng document and use

Summary: The features of Erlang are almost different from those of Erlang... Variable immutable: Guarantees atomicity and prepares for parallelism. Tuples: Similar to the structure in C language. Person = {person, {name,joe}, {height,1.82}. }. List: [H | T]. The list starts with H and ends with T. The vertical line symbol (|) can separate the header and tail of the list, while [] is an empty li

-Cause In the last group of services recently, the CPU usage of some node servers is very low, with only 1/4 of other servers. Eliminate service imbalance and suspected it was a system top statistics error. We found it through Erlang: Statistics (scheduler_wall_time) from the Utilization Survey of Erlang scheduler) check that the actual CPU usage of the machine scheduler with low server CPU is close to 100%

Let's look at its source code: 1 send(S, Data, OptList) when is_port(S), is_list(OptList) -> 2 ?DBG_FORMAT("prim_inet:send(~p, ~p)~n", [S,Data]), 3 try erlang:port_command(S, Data, OptList) of 4 false -> % Port busy and nosuspend option passed 5 ?DBG_FORMAT("prim_inet:send() -> {error,busy}~n", []), 6 {error,busy}; 7 true -> 8 receive 9 {inet_reply,S,Status} ->10 ?DB
