Web print is still shit, even for CSS2 print features

Having spent ten yours out of the loop, I had somehow expected browser makers to take some time out of their favorite hobby—moving knobs and settings around—to implement CSS printing support. I'm all for saving paper and all, but requiring me to pipe my HTML through LaTeX to produce halfway decent documents doesn't feel very 2017ish to me. In 2007, it already didn't even feel very 2007is to me. Read More »

Which context does the circumflex accent (^) refer to in BULL?

^ refers to the last step left in the superpath, never to a step right. (In the A4 notes below, in red, I seem to disagree with what I say here.) Read More »

BULL TiddlyWiki

At some point, I started condensing some paper and digital notes into a TiddlyWiki, which seemed like an appropriate tool for a personal project. Looking at the timestamp (July 26 of 2013), this choice doesn't make sense, because at that time I had already started this blog and discovered the joy of indexical knowledge management based on links between temporal blurbs (as within a blog) rather than links between named blurbs (as within a wiki). I guess it had everything to do with wanting the execution of the BULL idea to be perfect before daring to share. It's definitely time to get over that. Read More »

BULL progress and stagnation

At work yesterday, during lunch, I started a lengthy discussion that stretched out long beyond the boundaries of regular lunch hours. The discussion topic was my surprise that IT practices—particularly programming methodologies—hadn't changed much, if at all, between my leaving the industry in 2007 and re-entering the industry in 2015. My surprise wasn't a rethorical technique; my unpreparedness for this lack of change has lost me a long-running bet with Wiebe around 2007, when we stopped being colleagues for about 8 years. The content of that bet was as follows: I predicted that in 10 years time—now—computer science would have sufficiently evolved so that software would behave intelligently. In fact, I didn't believe that AI would have emerged by now, but I did expect software architecture to have changed in such a fundamental way that computers would at least have behaved intelligent, even if they weren't self-taught and self-learning.
