Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

~~Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.~~

Service Worker - offline support for the web

Progressive apps - high-res icon, splash screen, no URL bar, etc.

Generate private key (.key)

# Key considerations for algorithm "RSA" ≥ 2048-bit
openssl genrsa -out server.key 2048

# Key considerations for algorithm "ECDSA" ≥ secp384r1
# List ECDSA the supported curves (openssl ecparam -list_curves)

Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

	// Package GinHTMLRender provides some sugar for gin's template rendering
	//
	// This work is based on gin contribs multitemplate render https://github.com/gin-gonic/contrib/blob/master/renders/multitemplate

	// Usage
	//
	// router := gin.Default()
	//
	// // Set html render options
	// htmlRender := GinHTMLRender.New()
