CentOS7安装思源黑体(Source Han Sans)方法
因为要视频在服务器上面打上中文字幕,所以需要装一款中文字体。看着前端时间非常火的思源黑体 (Source Han Sans) 并且免费开源的字体,于是我将这款字体装到了操作系统为CentOS7的这台机子上面了。
思源黑体是一套 OpenType/CFF 泛中日韩字体。所谓OpenType,其实就是OTF这种格式的文件。让人高兴的事CentOS上面有原生支持(Windows似乎没有),也难怪叫做Open。

生命的意义(meaning of life)——这是一个哲学家们经常讨论的问题,也似乎是一个非常重要、迫切的问题。相信很多人都曾经思考过、寻找过。
人生来是为了什么?人生有什么意义?我为什么在这里?人为什么存在?我为什么要活着?——这些问题其实都关涉到相同的一个点,就是“生命的意义”。
这两天虽然很忙,但是由于某些情况需要折腾一个反向代理服务器。解决了我一个困扰了很久的问题——为什么nginx不能检测后面php-fpm或者hhvm运行的状态;如果php-fpm或者hhvm挂了为什么nginx的fastcgi_cache_use_stale的参数不起作用?
我一直想当php-fpm或者hhvm挂掉的时候nginx能够提供cache的旧页面,但是fastcgi_cache_use_stale的参数似乎不起作用,今天仔细地读了一个nginx的文档。为了实现这个目的,我们需要用的是fastcgi_cache_use_stale 中 error这个参数,然而error这个参数的说明中提到了一句话
This course includes TCP/IP architecture. 这是一门有关网络的基础课程,主要涉及Layer3-5。
This course introduce very fundamental network knowledges. It covers some old technology but that is very critical.
We will study the TCP/IP protocol through out the whole course. Advance topics includes P2P system, multimedia communication (VoIP), network security(IPSec SSL), wireless sensor networks. Top-down approach. Start from top(Application) to bot(Network). More algorithmic. More programming.
Simple core, but complex edges.

[专业笔记] Algorithm, Data Structure, Java, 代码
数据结构课程,其实用Java而不是用C / PASCAL来讲让我有点不太适应。
This content is for YorkU EECS 2011. As usual, I will post some "interesting" course note. This course is not that difficult. And our prof's ppt is so nice. Try not to miss any lecture and you will learn a lot from him. My professor is Andy Mirzaian.
网上现在大部分的教程(包括苹果官方的CloudKit Quick Start)讲述的都是一种简易的方法(convience methods),我这里将要讲述的是如何有效使用队列进行数据库操作,使得操作更加有效规范可控。
This course introduces very very fundamental C/shell programming skills on linux.
We are using C89 standard in this EECS 2031 course. That means you cannot declare the iterator variable in a for loop. And you should be very careful when you are trying to copy any C code from Google or Stack Overflow. Because those code fragments might be written in C with C99 standard or Cpp. Professor is very nice but TAs are not that efficient. We have to wait a long time for the grading.
EECS2030课程的笔记
This content is for YorkU EECS 2030. I took this course in summer 2016. My professor Navid Mohaghegh is a very nice professor. I do strongly recommend his course.
