django_select2 and tastypie

By On 2013.05.03 · Leave a Comment

This is a pretty niche scenario, but if video games taught me anything…

My company already set up tastypie and its ModelResource classes. Everything was great, and like true idealists we knew that one day we would want to power our own frontend AJAX (auto-completes, datatables, big SelectMultiple widgets, etc) with our own API. [...]

TextMate 2 ignoring existing environment variables

By On 2013.02.08 · Leave a Comment

For most uses, the .tm_properties file itself serves as an environment setup, and for other uses, configuring certain static variables directly in Preferences will solve your environment variable problems.

But if you have secrets and you’ve used system variables in /etc/environment or ~/.MacOSX/environment.plist, you may have noticed that TextMate 2 was ignoring them [...]

Submitting Javascript File API data synchronously

By On 2013.02.04 · Leave a Comment

The Javascript File API is cool stuff, especially when you combine it with the emerging drag-and-drop API events. Some pretty simple building blocks make a lot of sophisticated interface designs possible.

Dropping an image file onto a page and catching the event is pretty straightforward. We used to think the only way to [...]

django-tastypie url names

By On 2013.01.31 · Leave a Comment

The url naming scheme in tastypie is kind of unguessable for someone hoping for an easy ride.

To find the names for your current version (I doubt they’d change, given the miniature rant below), you would be best served by checking out the source, at tastypie/resources.py in the method called base_urls (make sure [...]

Why Django doesn’t need better urls.py

By On 2013.01.31 · Leave a Comment

Response to June 2012 article: http://warp.byu.edu/site/content/1100

The article is coming up on its first birthday, but it’s on the web, and I found it by mistake while searching for an unrelated topic.

The argument

The argument of the author, a teacher of Java, was that the Django urlconf system is too verbose and [...]

Capturing tricky script output in TextMate’s HTML output window

By On 2013.01.29 · Leave a Comment

Several of the more complex programs I try to execute from a TextMate command don’t uniformly echo their output the same way. This frequently led to programs behaving nicely in a chain of stream-processing bash commands (like sed), but some of the output was mysteriously missing.

Suddenly, as the script ends, a bunch of extra [...]

Textmate HTML output window blank

By On 2013.01.28 · Leave a Comment

While designing an HTML output, I’ve discovered at least one horribly, soul-punishing, tormenting behavior that probably made a part of me die inside.

While echoing output to the HTML window, if it encounters the following, it will be outright blank, with no explanation whatsoever:

<html><head><link type=”text/css” rel=”stylesheet” href=”$PATHNAME” /> …

Infuriatingly, the document goes [...]

Where is virtualenvwrapper.sh?

By On 2013.01.21 · Leave a Comment

Using Macports on OS X is beautiful, but sometimes when you install a library, it does something unexpected. No so wholly wrong that you think the creator is stupid, just messed up enough to detour you for 20 minutes while you figure out what happened.

I like to keep my list of install ports short—I’d [...]

Textmate Theme: Reset fontStyle to normal

By On 2012.10.23 · Leave a Comment

This is extremely miscellaneous, but the only place I could find a solution was in the Textmate source code itself. Maybe the query is just too broad or non-specific for the vast Internet of mailing lists and such.

When making a theme, if you have a scope that makes something bold, and then some element [...]

Base64 encode in Chrome

By On 2012.04.10 · Leave a Comment

WHY IS THIS SO HARD TO FIND?!

Original answer comes from the blessed stackoverflow: http://stackoverflow.com/questions/246801/how-can-you-encode-to-base64-using-javascript/247261#247261

The “btoa(…)” and “atob(…)” functions are the answer.  The names are as bad as they come these days, and impossible to find.  When dealing with extension development, this sure beats having to include a stupid Base64Encode script to do [...]
