Instructions

CloudFlare is an awesome reverse cache proxy and CDN that provides DNS, free HTTPS (TLS) support, best-in-class performance settings (gzip, SDCH, HTTP/2, sane Cache-Control and E-Tag headers, etc.), minification, etc.

1. Make sure you have registered a domain name.
2. Sign up for CloudFlare and create an account for your domain.
3. In your domain registrar's admin panel, point the nameservers to CloudFlare's (refer to this awesome list of links for instructions for various registrars).
4. From the CloudFlare settings for that domain, enable HTTPS/SSL and set up a Page Rule to force HTTPS redirects. (If you want to get fancy, you can also enable automatic minification for text-based assets [HTML/CSS/JS/SVG/etc.], which is a pretty cool feature if you don't want already have a build step for minification.)
5. If you

IPTABLES TABLES and CHAINS

IPTables has the following 4 built-in tables.

1) Filter Table

Filter is default table for iptables. So, if you don’t define you own table, you’ll be using filter table. Iptables’s filter table has the following built-in chains.

This is a document full of notes of all the things that have hung me up getting into Python's new asyncio library. I mostly use it for tools that schlep data around between file systems, databases, and search engines for work. So lots of io. Usually I use gevent and python 2.7. But recently I've been trying to get more into asyncio and here I'm going to document all the things that I felt important to know or that tripped me up.

1. Thoroughly understand yield, and non asyncio coroutines

The first thing you need to do is write some coroutines without asyncio. This means understanding the yield keyword and how it can be used to create generators. Then next the protocol for sending/receiving from generator objects.

Recall generators are a special kind of iterator. When you specify a generator like so, you can use it in a for loop:

def generator()

for i in range(0, 5):

This demonstrates how to make client side certificates with go

First generate the certificates with

./makecert.sh test@test.com

Run the server in one terminal

go run server.go
