Building

go build -o goencrypt main.go

Generating Keys

Golang Workers / Job Queue

A running example of the code from:

This gist creates a working example from blog post, and a alternate example using simple worker pool.

TLDR: if you want simple and controlled concurrency use a worker pool.

docker用来隔离应用还是很方便的，一来本身的操作较为简单，二来资源占用也比虚拟机要小得多，三来也较为安全，因为像数据库这样的应用不会再全局暴露端口，同时应用间的通信通过加密和端口转发，更加安全。

Gitlab是目前比较流行的开源类Github代码管理平台。Gitlab使用Rails开发，使用PostgreSQL或MySQL数据库，Redis做缓存。一般自己搭建私有代码仓库，Gitlab通常是首选。这里简单介绍一下dockerized Gitlab。

Gitlab的docker镜像早已有人做好了，并且维护相当不错。大家可以前往其GitHub仓库了解该镜像的情况。官方repo的readme中已经有详细的安装配置方案，这里我简单的梳理一下部署流程。

安装Docker

这里以Ubuntu 14.04发行版为例，在bash中输入一下命令安装最新的docker：

how to compile

$ gcc -g -Wall -I /path/to/libuv/include /path/to/libuv/uv.a -framework CoreServices server.c -o server
$ gcc -g -Wall -I /path/to/libuv/include /path/to/libuv/uv.a -framework CoreServices client.c -o client

Create a Meteor app and put the client_/server_ files in a client/server directories. Also, create a public dir to save the uploaded files.

Sass/Less Comparison

In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.

For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.

	local redis_c = require "resty.redis"


	local ok, new_tab = pcall(require, "table.new")
	if not ok or type(new_tab) ~= "function" then
	new_tab = function (narr, nrec) return {} end
	end


	local _M = new_tab(0, 155)

	func ResizeImg(spath string, tpath []string, size []image.Point) (int, error) {
	if len(tpath) != len(size) {
	log.Println("GetImgThumb: ", tpath, size)
	return 0, errors.New("GetImgThumb length unsafe")
	}

	cnt := 0
	for i, tgt := range tpath {
	log.Println("+++", spath, tgt)
	_, err := os.Stat(tgt)

	package main

	import (
	"bufio"
	"log"
	"net/rpc"
	"os"
	)

	func main() {
