Heroku is great! However…
I like Heroku. We’ve recently made our first deployment on it, and all things considered, I don’t think we could’ve made a better platform choice at this time. Deploying to Heroku taught me quite a few things, easily the most important of them was hearing about the 12 Factor App methodology. If you haven’t heard…

I wish someone wrote django-static-upstream… maybe even… me!
I used to think serving static files (aka static assets) is really easy: configure nginx to serve a directory and you’re done. But things quickly became more complicated as issues like asset compilation, CDNs/scalability, file-specific custom headers, deployment complexity and development/production parity rear their ugly heads. Judging by the huge number of different asset management…

Walking Python objects recursively
Here’s a small function that walks over any* Python object and yields the objects contained within (if any) along with the path to reach them. I wrote it and am using it to validate a deserialized datastructure, but you can probably use it for many things. In fact, I’m rather surprised I didn’t find something…

enqueue: CLI utility to queue command execution
Update: As you can see in the comments below, and as I feared, it turned out that Lluรญs Batlle i Rossell already implemented something much like Enqueue, only better in many regards. I doubt I’ll keep maintaining enqueue, there’s no reason to. Oh well, it was a nice afternoon project. Something that always bugged me…

nginx+gzip module might silently corrupt data upon backend failure
There are several elements that make absolutely certain the page you’re reading in your browser is an accurate representation of the resource the HTTP server meant to send you1. Disregarding caching for a minute, we have two elements making sure the representation you get is protected from errors. The first protecting element is, of course,…

zsh and virtualenv
A week ago or so I finally got off my arse and did the pragmatic programmer thing, setting aside those measly ten minutes to check out virtualenv (well, I also checked out buildout, but I won’t discuss it in this post). I knew pretty much what to expect, but I wanted to get my hands…

Python’s Innards: Hello, ceval.c!
The “Python’s Innards” series owes its existence, at least in part, to hearing one of the Python-Fu masters in my previous workplace say something about a switch statement so large that it was needed to break it up just so some compilers won’t choke on it. I remember thinking then: “Choke the compiler with a…

Python’s Innards: Interpreter Stacks
Those of you who have been paying attention know that this series is spiraling towards what can be considered the core of Python’s Virtual Machine, the “actually do work function” ./Python/ceval.c: PyEval_EvalFrameEx. The (hopefully) last hurdle on our way there is to understand the three significant stack data structures used for CPython’s code evaluation: the…

Python’s Innards: for my wife
The other day the best wife I’ll ever have had trouble sleeping and asked me to tell her something to put her to sleep. Since she’s not quite a hacker, I figured some discussion of what I usually write about may do the trick (okay, maybe ‘not quite a hacker’ is an understatement, she’s an…

Python’s Innards: Code Objects
This article, part of a series of articles about Python’s internals, will continue our preparation to engage the machinery of code evaluation by discussing Code Objects. To those of you who just now joined in and didn’t even read the introduction (but why?!), please note an important disclaimer: while the series as a whole is…
