Cassandra CQL 执行效率

目标

• 对推送保存记录表push_app_task push_device_task的查询：
  1. 主KEY上的搜索（partitionKey和带上clusterKey的区别）
  2. 索引上的搜索（单个和多个的区别，单个索引上少值和多值的区别）
  3. 混合主Key和Index上的搜索

4. 表上的聚集操作（计算count(*)）和 迭代累加计数

Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

rb2k

// Check if a slave has < 10 GB of free space, wipe out workspaces if it does

import hudson.model.*;
import hudson.util.*;
import jenkins.model.*;
import hudson.FilePath.FileCallable;
import hudson.slaves.OfflineCause;
import hudson.node_monitors.*;

for (node in Jenkins.instance.nodes) {

1 普通匹配，遵循最长匹配规则，假设一个请求匹配到了两个普通规则，则选择匹配长度大的那个
  例如： 
  location /{
    [matches]
  }
  location /test{
    [matches]
  }
2 精确匹配
  location = /{

To generate a pom.xml file just run gradle writeNewPom

If you want to generate it as pom.xml in the root of the project, replace writeTo("$buildDir/newpom.xml") with writeTo("pom.xml")

Unionize: network superpowers for your docker containers

Unionize lets you connect together docker containers in arbitrarily complex scenarios.

Note: I recommend to use https://github.com/jpetazzo/pipework instead.

• pipework is a better name than unionize
• it's hosted on a "real" github repo instead of a small gist :-)

Now if you want Unionize, it's still here. Just check those examples.

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

http://www.techmeme.com/070812/p1#a070812p1

The two files are index.php (the homepage) and search.php (the search page)
