昨日教室自习之时,瞄见前方一位兄台正在用iPhone 6上YouTube,甚为流畅,故好奇之通过何许方式上之 答曰PPTP 闻之后甚为惊异,又问其VPS架于何许地也
Hi, Windows 10~
继几个月之前的一天晚上硬盘突然爆炸迫不得已把系统从Windows 8.1换成Windows 7过后,前天又去作死给Windows 7开更新(其一是实在忍受不了那个带红叉的小白旗,其二也还是想给自己的Windows系统提升一点安全性),然后就走上了慢慢更新不归路,Windows的更新机制实在很DT,更新只能一部分一部分地安装,每次更新安装完成过后又得重启生效,所以折腾来折腾去花了十几个小时,最闹心的是最后依旧有两个安全补丁怎么安装也不成功,然后就进入了发现新补丁->下载安装补丁->配置失败->还原系统->发现新补丁死循环,就算是选择忽略掉了那两个补丁也会有可能因为安装更新一些Microsoft软件服务(比如Visual Studio和 Office)而取消屏蔽那两个更新,但如果我想要消灭小红叉,那么我必须打开自动更新,打开自动更新的话那两个安全补丁也有可能在未来的某一次开机里面跳出来然后配置来配置去十几二十分钟都进不了系统,好吧我承认我玻璃心我OCD我就是受不了这种说不定哪一天会不疼不痒地弄我一下的东西,从而再一次萌生了重装系统的冲动(反正Windows也不是主力开发环境),正好今天早上打开电脑就发现Windows 10正式版已经开始推送了,然后再小Google一下,搞到了Windows 10的iso镜像文件,干脆一不做二不休,直接抹盘把Windows 10给装上去了。
Simple implementation of ls command
Just an assignment from my Linux programming course. I have only done a small part of work of the ls command, after all, it’s a program with 400+ lines, if you want to study full source codes of ls command(in which there are 4000+ lines codes), you can get it from here.
