Using Graphics Card Memory as Swap (via) Interesting idea: “Graphic cards contain a lot of very fast RAM, typically between 64 and 512 MB. With Linux, it’s possible to use it as swap space, or even as RAM disk.”

I loathe [hardware load balancers]. They’re expensive, restrictive, slow, and generally cause you a lot more pain and suffering than they’re worth. At my last job, one of my projects was to convert most of one of our existing clusters from a load-balancing appliance to use keepalived. Why would we do this? Because the $100k worth of appliance wasn’t capable of doing the job that $15k worth of commodity hardware and an installation of keepalived were handling with ease.

Large Problems in Django, Mostly Solved: Search. Eric Holscher shows how Haystack uses a number of common Django patterns (object registration, pluggable backends, QuerySet-style chaining and class-based views) to great effect in creating a powerful search application for Django. Makes me wonder if more of those patterns should be promoted to first class concepts within Django.

HTML has always been a conversation between browser makers, authors, standards wonks, and other people who just showed up and liked to talk about angle brackets. Most of the successful versions of HTML have been “retro-specs,” catching up to the world while simultaneously trying to nudge it in the right direction. Anyone who tells you that HTML should be kept “pure” (presumably by ignoring browser makers, or ignoring authors, or both) is simply misinformed. HTML has never been pure, and all attempts to purify it have been spectacular failures, matched only by the attempts to replace it.
