在运行参数中设置silent参数：erl -kernel error_logger silent

Under the category of "Concurrent Oriented Programming", Erlang has got some good attention recently due to some declared success from Facebook engineers of using Erlang in large scale applications.   Tempted to figure out the underlying ingredients of Erlang, I decided to spent some time to learn the language.

Multi-threading Problem

Multiple threads of execution is a common programming model in modern languages because it enable a more efficient use of computing resources provided by multi-core  and multi-machine architecture. One of question to be answered though, is how these parallel threads of execution interact and work co-operative to solve the application problem.

There are basically two models for communication between concurrent&

安装erlang和cean，通过cean安装ibrowse：

wget http://cean.process-one.net/pub/bin/linux-x86_64/R14/cean/cean-2.0.sh

chmod +x cean-2.0.sh

./cean-2.0.sh

./cean/bin/ceanctl install ibrowse

=======================================

test.erl

-module(test).

-export([start/1]).

start(Filename) ->

    ibrowse:start(),

    true = filelib:is_regular(Filename),

    for_each_line_in_file(Filename, [read]).

for_each_line_in_file(Name, Mode) ->

    {ok, Device} = file:open(Name, Mode),

    for_each_line(Device).

for_each_line(Device) ->

    case io:get_line(Device, "") of

        eof ->

            file:close(Device), ok;

        Line ->

            io:format("~p~n", [Line]),

            ibrowse:send_req(Line, [], get, [], []),

            for_each_line(Device)

    end.

About PHPCrawl

PHPCrawl is a set of classes written in PHP for crawling/spidering websites, so just call it a webcrawler-library or crawler-engine for PHP.

PHPCrawl "spiders" websites and passes information about all found documents (pages, links, files ans so on) for futher processing to users of the library.

It provides several options to specify the behaviour of the crawler like URL- and Content-Type-filters, cookie-handling, robots.txt-handling, limiting options, multiprocessing and much more.

PHPCrawl is completly free opensource software and is licensed under the GNU GENERAL PUBLIC LICENSE v2.

To get a first impression on how to use the crawler you may want to take a look at the quickstart guide or an example. A complete reference and documentation of all available options and methods can be found in the classreferences-section

The current version of the phpcrawl-package and older releases can be downloaded from a sourceforge-mirror.

Note to users of phpcrawl version 0.7x or before: Although in version 0.8 some method-names and parameters have changed, it should be fully compatible to older versions of phpcrawl.

关键是这哥们是动态生成的，每次rebuild一次都要记得改回来

用2010用了两年了，一直没想过升级。最近想升级到XE2，测试之前的一些控件，有一些关键的还不能用，比如

Berg.Next.Component.Suite.v5.8.9.1

VirtualTreeview4.8.6

慢慢测试一下。

vst从svn上下载最新的代码，可以编译。不过默认居然选择的是64位，导致错误，在工程中选择32bit即可。

setup.ini应该这么写，将MultiInstaller和zip放在同一目录，目标目录选择当前目录即可：
