UOM Programming Proficiency/Competency Test

This is to introduce what is the University of Melbourne Programming Proficency/Competency Test, and how is it like. Information is based on my personal experience in Semester 2, 2016.

What is it?

The University of Melbourne Programming Proficency Test (also known as the Programming Competency Test), is served as one of the prerequisites to replace the subject COMP10001 Foundation of Computing. When passing this test at a score more than 75%, you are able to enrol to several subject including COMP10002 Foundation of Algorithm`.

The name of the test is not consistant throughout the materials provided by the university, but “Programming Proficiency Test” is rather used more commonly.

利用虚拟机软路由负载均衡拓展带宽

前提:

  • 假定所使用的计算机能够使用虚拟机(256MB RAM 512 MB HDD 应该没有什么带不动的吧),通过固定且稳定的方式连接到局域网。
  • 虚拟机的虚拟网卡能够正常工作。
  • 假定局域网设定每IP地址限速。

原理:

将虚拟机的网卡桥接到局域网,宿主机与虚拟机通讯获取数据。虚拟机上的软路由通过负载均衡将数据包均衡分配给多个桥接网卡。由于每个桥接网卡都有其自己的局域网IP,所以每个桥接网卡能够获得到同等的带宽。宿主机把自身的流量收发交给虚拟机来分配,其理论网速将得到提升。(实际下载速度提升仅限于P2P和多线程下载,一般的单线程P2S测速网站不能够体现效果,如Speedtest.net。)

PC和Android实现一键登录WLAN Web Auth的方法

好长时间没有发文了。明天还要大早起,现在正好趁着刻盘的时间把这个发出来吧,但是也不能睡太晚了。(顺便吐个槽,windows 光盘映像刻录机 速度真的很慢啊)

这次主要是说明一下快速登录部分WLAN的网页登陆(Web Auth)的方法。由于位置关系,就用最近的宿
