Introduction to Surlex. A neat drop-in alternative for Django’s regular expression based URL parsing, providing simpler syntax for common path patterns. # 11th April 2010, 7:23 pm

rev=canonical bookmarklet and designing shorter URLs

I’ve watched the proliferation of URL shortening services over the past year with a certain amount of dismay. I care about the health of the web and try to ensure that URLs I am responsible will last for as long as possible, and I think it’s very unlikely that all of these new services will still be around in twenty years time. Last month I suggested that the Internet Archive start mirroring redirect databases, and last week I was pleased to hear that Archiveteam, a different organisation, had already started crawling.

Django snippets: Sign a string using SHA1, then shrink it using url-safe base65. I needed a way to create tamper-proof URLs and cookies by signing them, but didn’t want the overhead of a full 40 character SHA1 hash. After some experimentation, it turns out you can knock a 40 char hash down to 27 characters by encoding it using a custom base65 encoding which only uses URL-safe characters. # 27th August 2008, 10:18 pm

The Python Property Builtin. The always-educational Adam Gomaa explains the Python property built-in and shows how it can be used to improve Django’s model-based URL generation. # 23rd August 2008, 1:08 pm

sorl-thumbnail. This looks like a decent attempt at a generic Django thumbnailing service, but I’m always wary of code that allows URL hackers to create large numbers of files that will be cached to disk. UPDATE: My mistake, thumbnail creation can only be caused by template authors. # 27th November 2007, 7:17 pm

ASP.NET MVC Framework. This looks pretty good. It includes clean URL support that’s very similar to how Django does things (with a nice alternative syntax for developers who don’t like regular expressions). # 22nd October 2007, 1:45 pm

Why you should be using disambiguated URLs

Good URLs are important. The best URLs are readable, reliable and hackable.
