                Notes from Peter Alvaro's talk at PWL, August 21, 2014
              
          
    "Consensus is impossible" is a gloss for "there's always an execution that doesn't terminate".
Once you've internalized that you can't distinguish slow nodes from dead nodes, how do you deal with that?
"When you're engaged in a battle of wits with a Sicilian and death is on the line, you certainly need to think about epistemic logic."
A correct distributed program achieves (nontrivial) distributed property X. So we need to ask:

is X even attainable?
what's the cheapest* protocol that gets me X? (* according to some cost metric)

    On the Viability of Erlang Releases and CouchDB

There has been some discussion on what versions of Erlang CouchDB
should support, and what versions of Erlang are detrimental to
use. Sadly there were some pretty substantial problems in the R15 line
and even parts of R16 that are landmines for CouchDB. This post will
describe the current state of things and make some potential
recommendations on approach.

    DDD, CQRS and Event Sourcing

In preparation for a new gig I'm reading up on the terms Domain-Driven Design, Command-Query Responsibility Segregation, and Event Sourcing. Here are a list of useful texts and talks that I've discovered so far. If anything is missing please leave a comment.
DDD


Eric Evans: What is a model? - "A model is not a UML diagram nor a certain layer of the software. [...]. It is a system of abstractions, it describes selected aspects of a domain, and can be used to solve problems related to that domain."
Eric Evans: What I've learned since the book - slightly longer talk on Eric's findings since he co-authored the book on DDD.
Eric Evans: Domain-Driven Design - As far as I can tell, the book on DDD. Haven't read it though.

    Erlang Tracing: more than you wanted to know

Rough Outline


What can be traced?
How can trace events be specified?
"match specifications": twisty passages, all alike
WTF, can I just use DTrace and drink my coffee/beer/whisky in peace?
Trace delivery mechanisms: pick one of two

    Testing Notes

At this time only the protocol buffers client supports client certificates. HTTP is not supported.
Setup

Setting up a Root CA

It is necessary to set up a Root Certificate authority to be able to create and sign certificates.

  
## Liberal Regex Pattern for Web URLs
The regex patterns in this gist are intended only to match web URLs -- http,
https, and naked domains like "example.com". For a pattern that attempts to
match all URLs, regardless of protocol, see: https://gist.github.com/gruber/249502
