My professional passion is in software engineering, security, and DevOps. My every-growing list of hobbies includes mountain biking, backpacking, running, hydroponic gardening, baking/cooking, gaming/VR, home automation, and home improvement. I’m not too active on social media, but I sometimes share musings on Twitter and on my blog. I currently work for a company called Molecula where I am building software to power the next generation of data analytics. https://www.codysoyland.com/blog/concurrent-python-awpug-talk-resources/ Thu, 28 Feb 2013 00:00:00 +0000 https://www.codysoyland.com/blog/concurrent-python-awpug-talk-resources/ I’m doing a concurrency/gevent talk tonight at the Austin Web Python User Group.

The old paradigm of thick servers and thin clients is getting outdated as the new web demands rich, fast, asynchronous, full-duplex messaging. The technologies that enable server-to-browser asynchronous messaging have been given the umbrella term “Comet,” and the number of ways to provide Comet services is growing constantly. The transport options include XHR-multipart, WebSockets, and Adobe Flash Sockets, among others. https://www.codysoyland.com/blog/django-template-tag-namespaces-now-possible/ Mon, 09 Aug 2010 00:00:00 +0000 https://www.codysoyland.com/blog/django-template-tag-namespaces-now-possible/ I’ve been interested in the Django template language for some time now, and I’ve admired much of its simplicity and extendibility. I even wrote a shell for it(screencast)and a two-phase template renderer. Having spent the time to understand how it works, I’ve also had my share of ideas on how to improve it (addition of “elif”, mathematical operations in variable tags, namespaces). The pony that I’ve been wanting the most is probably namespaces. https://www.codysoyland.com/blog/screencast-django-template-repl/ Wed, 17 Feb 2010 00:00:00 +0000 https://www.codysoyland.com/blog/screencast-django-template-repl/ Django-template-repl is a unique project aimed at providing debugging tools for the Django template language. I did a screencast to highlight its features. In this video, I describe how to use Django-template-repl’s management shell, template tag, and context-capturing features. Please grab the source or simply run: pip install django-template-repl https://www.codysoyland.com/blog/thread-safe-object-oriented-views-django/ Wed, 03 Feb 2010 00:00:00 +0000 https://www.codysoyland.com/blog/thread-safe-object-oriented-views-django/ An emerging design pattern in Django is the usage of class-based views. Writing views as classes is made possible by Python features that allow classes and objects to behave as callables, just like functions. They can help organize view code and promote reusability by offering a greater level of customization. However, callable objects sometimes have thread safety issues that developers are often not aware of. Update 2/2/11: This post is now mostly irrelevant, because Django will soon solve this problem with the newly-refactored generic view module in Django 1. https://www.codysoyland.com/blog/evaluating-django-caching-options/ Sun, 17 Jan 2010 00:00:00 +0000 https://www.codysoyland.com/blog/evaluating-django-caching-options/ Caching is one of the first things you can do when you need to start thinking about scaling. Among efforts such as query minimization, denormalization, code optimizations, compression, database tuning, indexing, and load balancing, caching remains one of the lowest hanging fruits in methods to lighten your server load and handle huge amounts of traffic. There are many options, and I chose to evaluate a few of the most interesting setups. https://www.codysoyland.com/blog/django-template-debugging-made-easier/ Sun, 13 Dec 2009 00:00:00 +0000 https://www.codysoyland.com/blog/django-template-debugging-made-easier/ When working with the Django template language, specifically writing template tags or trying out new template tags that are not well documented, it’s easy to fall into a testing loop that involves modifying your code, saving the file, causing runserver to restart, which could take some time for large projects, switching to your web browser, hitting reload, and viewing the results. This workflow can be repetitive and unproductive. I decided to improve template interpreter interactivity by writing a REPL for it, and I released the project as django-template-repl, which is freely available on Github and PyPI. https://www.codysoyland.com/blog/new-blog/ Sun, 13 Dec 2009 00:00:00 +0000 https://www.codysoyland.com/blog/new-blog/ I dropped my old styles and went with Mingus. I set up a new blog today with django-mingus and so far I’m pretty pleased. Basically, I had some missing features on my blog and I decided to take the lazy route and use this instead of building everything by scratch. It’s still Django, so I can hack it up all I want, so I think I made the right choice. https://www.codysoyland.com/blog/building-search-pip/ Sat, 31 Oct 2009 00:00:00 +0000 https://www.codysoyland.com/blog/building-search-pip/ I’ve begun using pip frequently for working with python packages in my virtualenvs. pip does a great job with installing (and now uninstalling) python packages, but it currently lacks a command that I miss from other types of package managers, such as aptitude and port – search. I’ve forked a Git mirror of pip on Github for the purpose of tooling it with a search command, and I’ve made some progress in the last few days getting it working. https://www.codysoyland.com/blog/introduction-surlex-slides-djangocon-2009/ Wed, 09 Sep 2009 00:00:00 +0000 https://www.codysoyland.com/blog/introduction-surlex-slides-djangocon-2009/ I have uploaded my slides from my lightning talk on Surlex at Djangocon 2009. Here is the link. https://www.codysoyland.com/blog/introduction-surlex/ Sun, 06 Sep 2009 00:00:00 +0000 https://www.codysoyland.com/blog/introduction-surlex/ Surlex (Simple URL Expression) is a language for matching and extracting text, similar to regex (regular expression). It works by generating a regular expression from a more concise syntax that is designed to produce easy-to-read url patterns. Installation Surlex is indexed in PyPI, so it can be installed via pip or easy_install: pip install surlex Alternatively, the source code repository is available via git: git clone git://github.com/codysoyland/surlex.git Basic Capturing A capture is performed by enclosing a variable name inside angle brackets: https://www.codysoyland.com/blog/serve-your-flac-and-ogg-files-itunes-firefly/ Sat, 05 Sep 2009 00:00:00 +0000 https://www.codysoyland.com/blog/serve-your-flac-and-ogg-files-itunes-firefly/ The Firefly Media Server is a killer app for serving your music collection to DAAP-compatible music clients (including iTunes for Mac/Windows and Rhythmbox for Linux). One of it’s features that might go unnoticed is its ability to transcode OGG and FLAC compressed files to raw uncompressed sound, bypassing iTunes’s incompatibility with those formats. Getting Started The current stable Firefly release, version 0.2.4.2, does not scan FLAC metadata, so the resulting database contains “Unknown” for all the artist and song columns. https://www.codysoyland.com/blog/quick-directory-changing-linux/ Mon, 15 Jun 2009 00:00:00 +0000 https://www.codysoyland.com/blog/quick-directory-changing-linux/ When working from a terminal, I often find myself typing the same commands over and over. There are a handful of long “cd” commands that I find myself typing regularly. I’ve found a few ways of speeding up my workflow by using some bash tools and tricks, and now I can usually get where I need to be with just a few keystrokes. Aliases Here are a few commands I find myself typing regularly:
