已经可以Ping通Google.com或者Google.com.hk了。但是怎么还是不能打开？ 原来是跳回到http了。
要强制https的话，以Chrome为例。可以打开 chrome://net-internals/#hsts
在 Domain 栏里，输入 google.com或者google.com.hk，并勾选下面的两个复选框，点击 “Add” 按钮即可。
强制 Google 网页快照使用 HTTPS，输入 googleusercontent.com。
强制 Google APIs 使用 HTTPS，输入 googleapis.com。
当然如果你嫌这个操作比较繁琐的话，可以安装插件HTTPS Everywhere。
1、查看系统
[root@localhost ~]# cat /etc/issue CentOS release 6.6 (Final) [root@localhost ~]# uname -a Linux localhost.localdomain 2.6.32-042stab106.6 #1 SMP Mon Apr 20 14:48:47 MSK 2015 x86_64 x86_64 x86_64 GNU/Linux
2、安装ShadowSocks
# yum install python-setuptools && easy_install pip
# pip install shadowsocks
3、创建配置文件/etc/shadowsocks.json
[root@localhost /]# touch /etc/shadowsocks.json
[root@localhost /]# vi /etc/shadowsocks.json
{
"server":"138.128.208.158",
"server_port":443,
"local_address": "127.0.0.1",
"local_port":1080,
"password":"MyPass",
"timeout":300,
"method":"rc4-md5"
}
备注：加密方式官方默认使用aes-256-cfb，推荐使用rc4-md5，因为 RC4比AES速度快好几倍。 继续阅读 »
netstat -lntu
as replied by @askmish will give you list of services running on your system on tcp and udp ports where
You don’t need the ‘p’ parameter as you’re only interested in getting which ports are free and not which program is running on it.
This only shows which ports on your system are used up, though. This doesn’t tell you the status of your network e.g. if you’re behind NAT and you want some services to be accessible from outside. Or if the firewall is blocking the port for outside visitors. In that case, nmap comes to the rescue. WARNING: Use nmap only on networks which are under your control. Also, there are firewall rules which can block nmap pings, you’ll have to fiddle around with options to get correct results.

netstat -peanut 用这个参数更可以列出是哪个程序在占用哪个端口
netstat -ano 可以直接列出PID，然后到任务管理器里面可以根据PID查看是哪个程序。

The ability to negotiate successfully in today’s turbulent business climate can make the difference between success and failure. With this in mind, Ed has reevaluated his list of top ten negotiation tips. Here are Ed Brodow’s Ten Tips for Successful Negotiating updated for the year 2016:
1. Don’t be afraid to ask for what you want. Successful negotiators are assertive and challenge everything – they know that everything is negotiable. I call this negotiation consciousness. Negotiation consciousness is what makes the difference between negotiators and everybody else on the planet.
Being assertive means asking for what you want and refusing to take NO for an answer. Practice expressing your feelings without anxiety or anger. Let people know what you want in a non-threatening way. Practice ‘I’ statements. For example, instead of saying, “You shouldn’t do that,” try substituting, “I don’t feel comfortable when you do that.”
Note that there is a difference between being assertive and being aggressive. You are assertive when you take care of your own interests while maintaining respect for the interests of others. When you see to your own interests with a lack of regard for other people’s interests, you are aggressive. Being assertive is part of negotiation consciousness.
“Challenge” means not taking things at face value. It means thinking for yourself. You must be able to make up your own mind, as opposed to believing everything you are told. On a practical level, this means you have the right to question the asking price of that new car. It also means you have an obligation to question everything you read in the newspaper or hear on CNN. You cannot negotiate unless you are willing to challenge the validity of the opposing position. 继续阅读 »
现在的笔记本、台式机，都不用BIOS，改成用UEFI了。
想要体验下UEFI但又不想在搞砸自己的系统咋办？
当然是在免费的VMWARE PLAYER里面使用UEFI了！
但是UEFI默认在VMWARE PLAYER里面是关闭的。这个时候就需要使用这个OpenSource的工具了：
打开这个Enable “efi” BIOS boot type，你就可以体验UEFI了。
现在磁盘分区升级成GPT，主板引导也变成EFI。虽然可以用Ghost 11.5，但是感觉不大好用…
研究了一下，推荐Macrium Reflect。简单易用的操作界面，备份、克隆速度也不错！
关键还是免费软件～ 🙂

这下满意了吧？
最近在Ubuntu上安装LAMP，并假设Wordpress。发现权限无论怎么设，除非设置为执行Apache的用户，才能避开这个问题。
弄了半天，最后发现在wp-config.php里面加入这句话可以解决这个问题：
define('FS_METHOD', 'direct');
在安装完Win10以后，才发现居然没有打开硬盘的AHCI模式。怎么办？
别急，其实很简单。不用重装Win10的。照下面步骤来就行。
bcdedit /set {current} safeboot minimal
bcdedit /deletevalue {current} safeboot
