A history of Semantic Networks [via robot wisdom]: "A semantic network or net is a graphic notation for representing knowledge in patterns of interconnected nodes and arcs. Computer implementations of semantic networks were first developed for artificial intelligence and machine translation, but earlier versions have long been used in philosophy, psychology, and linguistics. What is common to all semantic networks is a declarative graphic representation that can be used either to represent knowledge or to support automated systems for reasoning about knowledge. Some versions are highly informal, but other versions are formally defined systems of logic. Following are six of the most common kinds of semantic networks, each of which is discussed in detail in one section of this article." Those six network types being: Definitional; Assertational; Implicational; Executable; Learning; Hybrid.
Moments of San Francisco culture shock:
America is unarticulably weird|cool.
A topical Upsideclown up at the moment. "A sin every three or four days. One hundred sins a year. That's a good market. Jesus died for all our sins, but wouldn't it be better, more certain, if he could die for each one? [...] Cloning is really a simple matter. We farm the embryos in vats, keep them growing long enough that it's absolutely certain the spark of life has entered the cell cluster, then ship them out in little plastic cartridges. People pop them like breath-mints, whenever their soul feels dirty". New story: Seeing the Light.
Girls Are Pretty (April 15th entry) is still the second-best place on the entire www. "Also, I hope this doesn't fuck things up in some way, the way you can alter destiny bytime traveling. I'd hate to think that you'll end up underneath someone's moleberry tree and look down at the ground and see a whole mess of black and red and purple moleberries ground into the ground and you'll think "Oh shit, this is it. It's gonna happen right now" and then you'll run away or move too fast or something. If the kiss doesn't take place, we'll probably all end up all of a sudden being ruled by cats who know how to use phones".
(While you're there, scroll down to the April 3 entry, A Golden Glow Inside The Baby Day!. It's even better.)
Some good views on the way to San Francisco. Beautiful.

Things about Penrose Tiles:
I had fun this weekend making my own. (And I have to get this down before I forget the sensation. That when I started putting the tiling together, I was getting holes after only two or three. The first patterns were nice, but it wasn't tessellating. Then I started seeing patterns and simularities and putting down the tiles became easier, but there was something else behind my eyes. Unarticulable hypotheses being created and tested. I felt shifted into a different world of interaction, shifted sideways. Making those original patterns was unworkable, I could see imperfections I hadn't noticed before. Certain configurations were ugly in ways I hadn't seen a minute or so earlier. It felt like learning a new computer language, only more fundamental; or reading a book from a different field, only less to do with words. As if all lever-like behaviour in the world because turning behaviour instead. Then it was time for dinner, and it was difficult because the act of laying down the tiles correctly was compelling. The pattern demanded to extend.)
