The Book Of Shaders is an interactive #WebGL #tutorial #ebook with live GLSL code. Its homepage won’t load if you have WebGL disabled (and will make your browser unusably slow if you have it enabled but with an inefficient renderer), but the individual chapters will, like this one about math functions that are useful for shaping things. This chapter for some reason fails to render any of the shaders in my Chromium, maybe because it’s getting the error, “INVALID_ENUM: texImage2D: invalid texture type”.
"The #Physics of Scales", an #ebook #pdf about how modern physics (Maxwellian electrodynamics, gauge theory, quantum mechanics, and relativity) are not scale-free. #toread

This is the spec for Glulx, a three-operand 32-bit #virtual-machine designed by #Andrew-Plotkin aka Zarf, one of the leading #interactive-fiction authors as a simpler and less limited replacement for the #Z-machine, with Huffman string compression, integer and floating-point math, a standardized savegame format, no built-in object tree, and a dynamically-allocated heap. #toread
"Rossum" has moved his blog, full of amazing hardware hacks, off of the defunct Posterous.
lecture notes on how #Hindley-Milner type inference works in OCaml, with a simple OCaml implementation. Except, no, actually they’re implementing a much simpler type-inference algorithm, which is why it’s so simple.

a very brief description of #K.
Part of a set of excellent #tutorial pages on #WebGL, providing some handy helper functions to keep boilerplate to a minimum.
#WebGL #documentation online; this particular page is for built-in functions that return approximate partial derivatives of an arbitrary computed quantity relative to the window x and y coordinates in a fragment shader.
Another #WebGL GLSL #tutorial, this one from Paul Payne, lecturer at the Northern Sydney Institute of Tafe.

A #WebGL graphing calculator, to visualize the results of WebGL fragment shader expressions with a line plot.
Oh hey, #WebGL and GLSL have Perlin noise (or Perlin’s improved noise function called “simplex noise”) built in. Or almost; apparently this isn’t quite Perlin noise, but it’s similar.
Shadertoy is like a jsfiddle for #WebGL shaders I guess? With an FPS meter! Unfortunately this particular shader runs at 0.3 fps on my machine, making my browser unusable!
#Andrew-Plotkin and Jason Shiga have teamed up to create an interactive (or, anyway, choose-your-own-adventure) #comics story, called "Meanwhile". This is going to be interesting.
Jason Shiga wrote a remarkable #comics meditation on morality (or psychopathic amorality) and immortality called "DEMON", which he has finally finished.
