@jacobian just tweeted: A little shitty-wifi-inspired hack to make pip install not have to touch the ‘net at all: http://bit.ly/IRrRcn Yeah, been there, done that (using PIP_DOWNLOAD_CACHE). It’s a good idea, but pip itself has better support for doing this. I learned this technique from the pip development team, specifically @carljm over IRC and some bugs. [...]

But, each encrypt and decrypt using PBKDF2 can take a pretty long time (on my system, about 150ms for each hashing, which happens twice per unit test that I’m writing). For your test cases, (that create users and log [...]

So, you want to pass an array of values into a Form in Django. It’s not exactly obvious what the right solution is. You could read up on MultiValueField (https://docs.djangoproject.com/en/dev/ref/forms/fields/#multivaluefield) or you could read about widgets.MultipleHiddenInput (https://docs.djangoproject.com/en/dev/ref/forms/widgets/#multiplehiddeninput) but you’ll realize that neither of these allows for custom validation of the individual entries. Here’s a generic [...]

It’s possible to have an array-valued field in a Django Form, it’s just really, really not clear how to do it. Background: I’m writing a series of REST APIs using a Django backend, and I like to define the parameters for POST and PUT as Django Forms objects. I’m never rendering my Forms as HTML, [...]

Our Jenkins build was working great (archiving one workspace, and then untarring it into another using the Archive for Clone Workspace feature) and then one day it broke. The error was in the second build job, and says: at hudson.model.Run.run(Run.java:1421) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:238) Caused by: java.io.IOException: Failed to chmod /var/lib/jenkins/jobs/oswebsite_test/workspace/wsve/lib/python2.6/UserDict.py : Operation [...]

Yeah, that’s quite a cast of characters isn’t it? If you’re using emacs, and inside emacs you use ido-mode, then it is, by default, attempting to use “tramp completion” which, by default, is using dbus, which, by default, uses avahi (i.e. zeroconf) to browse your network for shares. What this means is that if you [...]
Continue Reading →Hey, so, you’re in town for PyCon and you’re staying at or near the Santa Clara Convention Center. Your first reaction is: Ugh, is this really as cool as Silicon Valley is? The answer is NO! Of course not! Santa Clara is kind of the armpit of the valley, so it’ll kind of be a shame [...]
Continue Reading →Here are some more brief thoughts on why extreme RESTful ness is a bad idea: As soon as you’re debating whether an API endpoint should be a PUT, POST or PATCH, you’re wasting your time. If you, as the API developer, can’t decide which method is appropriate for a given action, then you’re almost certainly [...]
Continue Reading →There’s always a lot of talk on programmer’s blogs about RESTful APIs. Of particular note are articles like this one, which talks about how Ruby on Rails is switching to a brand new HTTP method “PATCH”. Here’s the big issue: API design should have nothing to do with which transport you’re using. and HTTP is [...]
Continue Reading →So, you’ve installed Jenkins on Ubuntu (following the directions on their Wiki page) but you want it to listen on a different port (the default is 8080). I’m really, really surprised that there’s not a config file for this. You have to edit /etc/init.d/jenkins. Add the following two lines at the top of the file [...]
