强制 Google.com 域名使用 HTTPS（SSL）

2016/08/01 by G0dspeed·0评论

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。

怎样安装ShadowSocks Server

2016/06/30 by G0dspeed·0评论

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

LINUX

netstat -lntu

as replied by @askmish will give you list of services running on your system on tcp and udp ports where

-l = only services which are listening on some port
-n = show port number, don’t try to resolve the service name
-t = tcp ports
-u = udp ports
-p = name of the program

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

Windows

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。

Ten Tips for Negotiating in 2016

2016/04/22 by G0dspeed·0评论

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
