1. Easy ETL with RDF and Python

    So I have been tasked with optimizing our deployment pipeline. It is pretty obvious to us where the bottlenecks are but trying to be a data driven developer I needed to collect stats on the current system to know for certain where the bottlenecks are in feature deployment.

    1. Websocket Demo Results V2

      History

      Roughly about a month ago I wondered if Erlang's promise of massive concurrency was actually true.

      Rather than take everyone's word for it, inspired by Richard Jones' C1M experiment I decided to whip together a benchmark of my own.

      This benchmark pit a Cowboy ...

      1. Learning Python Logging

        The Python logging module is often a source of confusion with developers. Often logging is the final thought in a project. When we are finishing up a project, the last thing we want to do is sift through the logging documentation to figure logging out. It is a perpetual cycle ...

        1. Books every self-taught computer scientist should read

          There are three books that I believe that every self-taught computer scientist should read. These are books that I often recommend to smart junior developers that learned their knowledge by doing instead of schooling. These are books that will close the gap for people that fall into the category of ...

          1. Why REST?

            Preface

            I have to say before you read this that I only have a theoritical understanding of how a web service benefits for being RESTful. Most of the topics I have explored are actually explained in Roy Fieldings section on REST

            In the future, I would like to explore and ...

                      PostgresSQL implements something called MVCC. Which alleviates the need for a Read-Lock in many cases. However when Glenn Franxman and I were trying to figure out how this works we were having trouble understanding it completely.

                                          CouchDB still seems to be a viable replacement for the BigTable backend to datastore. A GQL parser will have to be written to interface with Couch's views, but that's probably easy enough.
