                etcd vs consul vs ???
              
          
What do Etcd, Consul, and Zookeeper do?

Service Registration:

Host, port number, and sometimes authentication credentials, protocols, versions
numbers, and/or environment details.


Service Discovery:

Ability for client application to query the central registry to learn of service location.


Consistent and durable general-purpose K/V store across distributed system.

Some solutions support this better than others.
Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.


Centralized locking can be based on this K/V store.

    IP Tables (iptables) Cheat Sheet

IPTables is the Firewall service that is available in a lot of different Linux Distributions. While modifiying it might seem daunting at first, this Cheat Sheet should be able to show you just how easy it is to use and how quickly you can be on your way mucking around with your firewall.

The following list is a great set of documentation for iptables. I used them to compile this documentation.

    Create PDF files from Markdown sources in OSX

When [Markdown][markdown] appeared more than 10 years ago, it aimed to make it easier to express ideas in an easy-to-write plain text format. It offers a simple syntax that takes the writer focus away from the formatting, thus giving her time to focus on the actual content.
The market abunds of editors to be used for help with markdown. After a few attempts, I settled to Sublime and its browser preview plugin, which work great for me and have a small memory footprint to accomplish that. To pass the results around to other people, less technical, a markdown file and a bunch of images is not the best approach, so converting it to a more robust format like PDF seems like a much better choice.
[Pandoc][pandoc] is the swiss-army knife of converting documents between various formats. While being able to deal with heavy-weight formats like docx and epub, we will need it for the more lightweight markdown. To be able to generate PDF files, we need LaTeX. On OSX, the s
