Makers and Making
An Article by Alan JacobsThe [Silmarils] are good; their making was at least potentially innocent; but afterward arose a lust for owning and controlling that led to great tragedy… The aspect of humanity which the elves represent most fully – both for good and ill – is the creative one.”
And this is why “making” in and of itself is not the answer to our decadent moment. “Love of things, especially artificial things, could be seen as the besetting sin of modern civilisation, and in a way a new one, not quite Avarice and not quite Pride, but somehow attached to both” – and this is the Fëanor Temptation. It is in light of this temptation that I advocate repair, which is a mode of caring for what we have not made, but rather what we have inherited. We will not be saved by the making of artifacts — or from the repair of them, either; but the imperative of repair has these salutary effects: it reminds us of our debt to those who came before us and of the fragility of human constructs.
Against Canvas
An Article by Alan JacobsEven with all the features and plugins, Canvas presumes certain ways of organizing classes that might not be universal, just typical. And if (like me) you’re an atypical user, you have to choose between constantly fighting with the system or gradually doing more and more things the way Canvas wants you to do them. This, by the way, is why it’s never true to say that technologies are neutral and what matters is how you use them: every technology without exception has affordances, certain actions that it makes easy, and other actions that it makes difficult or impossible. A technology whose affordances run contrary to your convictions can rob you of your independence — and any technology deployed on the scale of Canvas will inevitably do that. It will turn every teacher into an obedient Canvas-user. I don’t want to be an obedient Canvas-user.
But we're not there
A Fragment by Alan JacobsGet your fucking hands up
Get on out of your seats
All eyes on me, all eyes on me...But we’re not there. There’s a cheering-audience soundtrack, but it’s fake, Burnham knows it’s fake, he’s the one who put it there. He doesn’t know whether we’re watching, whether our hands are up, whether all eyes are on him.
Wang tiles
Wang tiles (Hao Wang, 1961) are a class of formal systems. They are modelled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them.
The basic question about a set of Wang tiles is whether it can tile the plane or not, i.e., whether an entire infinite plane can be filled this way. The next question is whether this can be done in a periodic pattern.
In 1966, Wang's student Robert Berger solved the problem in the negative. He proved that no algorithm for the problem can exist, by showing how to translate any Turing machine into a set of Wang tiles that tiles the plane if and only if the Turing machine does not halt. The undecidability of the halting problem then implies the undecidability of Wang's tiling problem.
