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.
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.
有时候我们需要一些深度定制的并且多次多次复用的UI控件，为了模块化程序，在iOS8 及以后，我们可以将常用的定制UI控件放到自己的Kit里面，在不同的项目中重复使用。
本文主要记录怎样定制UI控件
服务器还是很有维护成本，对于小团队来说，不可能将各种。用AppStore进行分发，其实就是将销售方面交由Apple管理；换而言之，如果是用CloudKit进行开发，可以理解是将后端的也交由Apple管理。Apple为小团队们节省了很多不必要的开支。关于CloudKit网上有很多翻译苹果提供的最新文档，但是个人总感觉那些人并没有理解就进行翻译（Markdown程序员？），根本没有什么用。这篇文章是基于原版的英文文档，以及2014和2015年WWDC的视频整理而成的。
本篇文章不适合初心者，并不会升面试效果。
考虑到网站上面一堆域名证书的续费成本，还是花了几个小时将给服务器装上了Let's Encrypt 的免费证书。其实还算挺简单的。总体来说，LE的证书还是挺可靠的，支持着有EFF、Mozilla等大头，虽然是2015年末才正式推出服务，但是一年多以前我就早已听到，当时好像还引发了很强烈的反响。
