It’s wired that when I tried to update the Ubuntu zesty and install some new packages today, I got such errors below. And none of the other mirrors works to me. All of them has the same issue “no longer have a Release file”. I did some research and found the error message actually has…

Introduction goRBAC provides a lightweight role-based access control (RBAC) implementation in Golang. Normally, the privilege information (roles, parents, and permissions) are saved in the persistent storage, e.g. Database, Files, or Cloud Storage. This post will briefly discuss the technical details of how to load the goRBAC instance from persistent storage and how to save the…

Code refactoring is not an easy job, but it has to be done in most of the times. I just completed the lightweight role based access control library: goRBAC’s refactoring. There are some feedbacks and questions about the design and usage. I think it would be better writing something to share some design ideas and…

Sunday, a triangular routing would be a perfect plan. I have to admit that the term is borrowed from the mobile network, but it can be figured out, isn’t it?

请注意，本文正文含有大量链接。如果是转载或者使用某些不支持超链接的阅读器，就请自行脑补吧。 近期，Go Team 连续放出了几个大招来介绍即将在八月问世的 Go 1.5 这个划时代的版本。Rob 和 Andrew 分别在《Go in Go》和《The State of Go》中详细说明了出现在 Go 1.5 中的重要特性和细节变化。在这个版本中最主要的变化是移除了所有 C 代码，不论是 runtime 还是编译器都使用 Go 语言和一小部分的汇编来实现——也就是人们常说的自举。但是这样做也就意味着，Go 在 1.5 和以后的版本中，使用源代码构建 Go 开发环境将面临“鸡生蛋，蛋生鸡”的麻烦（当然了，如果你直接“买鸡蛋”——使用二进制安装包——是没有这个问题的）。

个人来说，一直希望能将《Go指南》这个项目的版本管理从 bitbucket 迁移到 github。但是由于上游英文源项目仍然在用 hg 作为版本管理工具所以一直也没有这么做。前几天 OlingCat 找我，希望将这个翻译项目放在 github 上的 go-zh 项目中。我当然欣然同意，虽然翻译工作还得用 hg 维护，但是 git 上能够有个镜像也是不错的事情。 （中间略过若干 hg –> git 的鸡零狗碎不说） 在等待同步的时候，我简单阅读了一下“Go 项目翻译规范”，发现一个让我觉得很不舒服的设定。
