How to implement a custom search for Hugo usig Gruntjs and Lunrjs.

Requirements

Install the following tools:

• Nodejs
• Gruntjs

Setup

# 生成 dhparam.pem 文件, 在命令行执行任一方法:

# 方法1: 很慢
openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048

# 方法2: 较快
# 与方法1无明显区别. 2048位也足够用, 4096更强
openssl dhparam -dsaparam -out /etc/nginx/ssl/dhparam.pem 4096

G1GC v.s. CMS for Cassandra 2.0

Many people have asked me about using the G1 garbage collector with Cassandra. Since most of my customers are running 2.0 in production the test is with 2.0 for now. Once I script it up I'll re-run the numbers with 2.1.

I also need to re-test with Java 7 and the Oracle JDKs.

TL;DR
