    搭建trendingtopics

    <Category: 小道消息>

    https://github.com/datawrangling/trendingtopics
    https://github.com/datawrangling/spatialanalytics

    搭建trendingtopics,步骤。

    环境准备

    配置文件

    安装

    如果保错:undefined local variable or method `version_requirements’
    vi config/environment.rb
    在开头加入:

    安装mysql client和mysql gem

    配置数据库连接

    安装数据库

    生成100条文章来做demo数据

    server启动后,访问地址http://localhost:3000/

    报错:

    创建表 CREATE TABLE raw_daily_stats_table1 (redirect_title STRING, dates STRING, pageviews STRING, total_pageviews BIGINT, monthly_trend DOUBLE) ROW FORMAT DELIMITED FIELDS TERMINATED BY ‘\t’ STORED AS TEXTFILE; 加载数据 LOAD DATA INPATH ‘/home/dev/finalresult-a’ INTO TABLE raw_daily_stats_table; //文件路径为hadoop的文件路径,上面的路径对应为hdfs://platformB/home/dev/finalresult-a

    加载的时候如果报加载失败,检查你的hdfs,会发现生成了一个你的文件名+_copy_1的文件,然后你load这个文件就成了。 hive> show tables > ; FAILED: Error in metadata: javax.jdo.JDOFatalDataStoreException: Failed to start database ‘/var/lib/hive/metastore/metastore_db’, see the next exception for details.

    static site generator:jekyll

    <Category: 小道消息>

    Jekyll is a simple, blog aware, static site generator. It takes a template directory (representing the raw form of a website), runs it through Textile or Markdown and Liquid converters, and spits out a complete, static website suitable for serving with Apache or your favorite web server. This is also the engine behind GitHub Pages, which you can use to host your project’s page or blog right here from GitHub.

    sudo on cygwin

    <Category: Linux>

    有些时候必须要以root的身份执行,但是在cygwin下怎么做呢?

    windows Cygwin 下使用root权限的方法,sudo 方法
    修改C:\cygwin\etc\profile文件

    将对应的windows用户名的那条记录,将对于的记录
    medcl:unused:1001:513:Medcl’,U-BS-MEDCL\medcl,S-1-5-21-1781803582-33251031-1424578719-1001:/home/medcl:/bin/bash
    修改成如下,即成
    root:unused:1001:513:Medcl’,U-BS-MEDCL\medcl,S-1-5-21-1781803582-33251031-1424578719-1001:/home/root:/bin/bash

    注意,切换了目录和用户账户,之前的用户下的配置都没了哦,如ssh、svn账户信息等

    [转]Amdahl’s law (阿姆达尔定律)的演化和思考

    <Category: 分布式>

    From:http://manio.org/progress-and-thoughts-of-amdahls-law-286.html

    G.M.Amdahl在1967年提出了Amdahl’s law,针对并行处理的scalability给出了一个模型,指出使用并行处理的提速由问题的可并行的部分所决定。这个模型为并行计算系统的设计者提供了指导。

    其形式如下:

    f为问题中可被并行处理的部分的比例,m为并行处理机的数量,Speedup为并行后相比串行时的提速。
