Natan Rubin posted the full version of his paper On Kinetic Delaunay Triangulations: A Near Quadratic Bound for Unit Speed Motions to his webpage. The paper won the best paper award in FOCS 2013, and it is an impressive piece of work (its also long – 144 pages) – resolving an open problem that many people had tried to solve over the last decade or so.

When I reported the problem to the superintendent in charge of denying all responsibility for anything, ever, told me that he’d check out the missing pieces, if I wanted him to, while I filled out the claim forms, if I thought that was worthwhile – although it looked a lot to him, he said, as though the damage to my case was old stuff.

sarielhp.org/blog/?p=8155 Swift: A meditation upon a broomstick
This single stick, which you now behold ingloriously lying in that neglected corner, I once knew in a flourishing state in a forest. It was full of sap, full of leaves, and full of boughs; but now in vain does the busy art of man pretend to vie with nature, by tying that withered bundle of twigs to its sapless trunk; it is now at best but the reverse of what it was, a tree turned upside-down, the branches on the earth, and the root in the air; it is now handled by every dirty wench, condemned to do her drudgery, and, by a capricious kind of fate, destined to make other things clean, and be nasty itself; at length, worn to the stumps in the service of the maids, it is either thrown out of doors or condemned to the last use—of kindling a fire. When I behold this I sighed, and said within myself, “Surely mortal man is a broomstick!” Nature sent him into the world strong and lusty, in a thriving condition, wearing his own hair on his head, the proper branches of this reasoning vegetable, till the axe of intemperance has lopped off his green boughs, and left him a withered trunk; he then flies to art, and puts on a periwig, valuing himself upon an unnatural bundle of hairs, all covered with powder, that never grew on his head; but now should this our broomstick pretend to enter the scene, proud of those birchen spoils it never bore, and all covered with dust, through the sweepings of the finest lady’s chamber, we should be apt to ridicule and despise its vanity. Partial judges that we are of our own excellencies, and other men’s defaults!
But a broomstick, perhaps you will say, is an emblem of a tree standing on its head; and pray what is a man but a topsy-turvy creature, his animal faculties perpetually mounted on his rational, his head where his heels should be, grovelling on the earth? And yet, with all his faults, he sets up to be a universal reformer and corrector of abuses, a remover of grievances, rakes into every slut’s corner of nature, bringing hidden corruptions to the light, and raises a mighty dust where there was none before, sharing deeply all the while in the very same pollutions he pretends to sweep away. His last days are spent in slavery to women, and generally the least deserving; till, worn to the stumps, like his brother besom, he is either kicked out of doors, or made use of to kindle flames for others to warm themselves by.
“We are all going to hell, but programmers are at least going to make money out of it” — Thomas Ungar (Circa 1997)
One day I seemed to shut a door between me and all publishers’ addresses and book lists. I said to myself, Now I can write. Now I can make myself a vase like that which the old Roman kept at his bedside and wore the rim slowly away with kissing it. So I, who had never had a sister and was fated to lose my daugher in infancy, set out to make myself a beautiful and tragic little girl.

Since sqrt(x*y) = sqrt(x)*sqrt(y) we have
1 = sqrt(1) = sqrt(-1*-1) = sqrt(-1)*sqrt(-1) = -1.

“Ah, dear lady, it is with the greatest embarrassment that I have to confess that in this matter I must—with a degree of anguish you may well find hard to credit—relinquish my absolute commitment to the fulfillment of your every whim. Put plainly, I am not at liberty to divulge that information. There, it is said. Let us quickly move on from this unfortunate quantum of dissonance to the ground-state of accord which I trust will inform our future relationship.”
“So you’re not going to tell me.” Sharrow nodded.
“My dear lady,” the machine said, continuing to trundle after her. “Without saying so in so many words…correct.”
The arxiv sometime complains bitterly about figures being too large (i.e., it says your submission is too large, without giving any useful details [good job!]). There is a nice program sam2p tha does a very good job in converting bitmaps into eps/pdf files, and compressing them in the process. It is available as a package under debian/ubuntu.
The revolusion would not be televised – it would be first pixelated and then compressed.
