I toy with the thought of converting this here website to MediaWiki (which my host supports), as I am more efficient at editing there than at writing raw HTML in vi.
The wiki’s first articles would be:
- Two-dimensional design
- Hyperbolic tilings
- Arrangements of the color gamut in the plane
- Three-dimensional design
- Solid printing
- Posthuman speculation
- Political speculation
I’d continue to report new thoughts here, and then integrate them into appropriate articles. I wonder whether MediaWiki and WordPress play well together. I’m not aware of any personal website that combines blog with wiki, but it seems unlikely that nobody does it.
And now I wonder whether a wiki on my home box would help me keep track of the little files I write as notes on this topic or that, and the PDFs that I download to read someday, and the
keenspace.com, a free hosting service for comic strips, changed its name (not long after it was founded) to comicgenesis.com; but the old name still works, as do comicgen.com and (I just learned) toonspace.com and webcomicspace.com. Well, mostly.
Mostly it doesn’t matter whether you look at foo.comicgenesis.com, foo.keenspace.com or foo.comicgen.com; you get the same content. But sometimes images don’t show unless the address is foo.comicgenesis.com.
What’s going on here? Apparently these domains are not transparent synonyms for each other; but why would they be (flawed) mirrors?
Here, have a couple of Python scripts. Each creates an image file, 2^12 pixels square, each pixel of a different color.
colorshuffle.py puts the coordinates of each pixel in Gray code, assigns each bit to one of the color channels, and converts each channel back from Gray code to choose a color. The assignment is chosen at random from 141926400 possibilities.
colorfold.py is my attempt to re-create and extend this: it folds the square eight times to make a cube fitting the color space. The interesting part was maintaining continuity through multiple folds. This one has only 107520 possible outcomes; again they’re chosen at random. I don’t like the result nearly as much as the other, but you might!
You’ll need Python Imaging Library.
On my machine each takes less than two minutes, so with a simple shell script you can whip up hundreds overnight.
On a private mailing list, a novelist asks for suggestions: what technological hobbies might a bright teenager have, in Oakland circa 1975? Chemistry sets were mentioned, among other things.
I may have had a chemistry set at age 8 or so; memory is spotty. A few years later we got an electronics kit, consisting of a collection of elements in Lego-like blocks. There was a booklet, starting with easy things like a light switch and an electromagnetic telegraph relay. (Maybe I thought the latter was easy because Dad and I had made one, about the same time as the possible chem kit).
Then on the next page was an oscillator or something. No explanation of why it was an oscillator. I thought, well, if I can’t see for myself why it’s an oscillator, evidently I’m not cut out for this stuff; so I quietly abandoned it.
My adolescence in a nutshell.
Of course it never occurred to me that perhaps there was no explanation because I was not expected to understand an explanation; I was expected to treat the oscillator as a black box. (Not that I had the concept of “black box”, either!)
How old do you need to be to understand this gag from 1978?
My new telephone has dozens of ringtones and I hate them all: Newagey lo-fi orchestral crap, mostly laden with snare drums for some reason.
My last phone played the sound of an old-fashioned mechanical bell; the one before that, a pizzicato passage from a Ravel string quartet; before that, the quick part of Pachelbel’s Canon – in frankly electronic timbres that did not pretend to be an orchestra.
I want a ringtone that says “a digital device seeks your attention,” not one that sounds like something overheard on a cheap radio belonging to someone with no taste.
I’ve noticed some changes in jumping from MacOS 10.6.x to 10.9:
The keystroke Command Option Eject no longer puts the computer to sleep.
On the Dock, the active app indicator is much less visible. (later improved)
Scroll bars no longer have arrow buttons, so I can’t click to scroll slowly.
When I charge my telephone on USB, it’s no longer recognized as a volume. (I’ve since got an Android phone, with a tolerable interface.)
