Peta reduce.

1990 - A committee formed by Simon Peyton-Jones, Paul Hudak, Philip Wadler, Ashton Kutcher, and People for the Ethical Treatment of Animals creates Haskell, a pure, non-strict, functional language. Haskell gets some resistance due to the complexity of using monads to control side effects. Wadler tries to appease critics by explaining that "a monad is a monoid in the category of endofunctors, what's the problem?"

One Div Zero: A Brief, Incomplete, and Mostly Wrong History of Programming Languages


An awareness of the history of p-values might help deflate their swollen stature and encourage more judicious use. We were surprised to learn, in the course of writing this article, that the p < 0.05 cutoff was established as a competitive response to a disagreement over book royalties between two foundational statisticians. In the early 1920s, Kendall Pearson, whose income depended on the sale of extensive statistical tables, was unwilling to allow Ronald A. Fisher to use them in his new book. To work around this barrier, Fisher created a method of inference based on only two values: p-values of 0.05 and 0.01 (Hurlbert and Lombardi, 2009). Fisher himself later admitted that Pearson's more continuous method of inference was better than his binary approach: “no scientific worker has a fixed level of significance at which from year to year, and in all circumstances, he rejects [null] hypotheses; he rather gives his mind to each particular case in the light of his evidence and ideas” (Hurlbert and Lombardi, 2009: 316). A fair interpretation of this history is that we use p-values at least in part because a statistician from the 1920s was afraid that sharing his work would undermine his income (Hurlbert and Lombardi, 2009). Following Fischer, we recommend that authors report p-values and refrain from emphasizing thresholds. This will allow us to more easily interpret evidence on a continuum and in the context of previous findings.

On Track.

By the 1930s passengers could travel from the English channel to Cairo with only three changes of train. The last leg, in third class, cost the equivalent of about two days’ work for a labourer. It left Haifa daily at 0830, steamed south to the Mediterranean port of Gaza by lunchtime, turned west into Sinai and arrived in the Egyptian capital by 2230.

From there, travellers could continue aboard one of the first air-conditioned carriages along the Nile to Luxor’s Valley of the Kings and on to Sudan. “Direct and quickest route to Damascus, Beyrout, Baalbek and Aleppo,” read a Palestine Railways brochure advertising the connections from Haifa.

He wears a cycling outfit under his clothes. He gets the money, flees the bank, and heads to a secluded spot about a block away from the bank. He takes off the robbery clothes and puts them in a bag, along with the money, and adds cycling shoes, a helmet and glasses to his outfit, and he heads out on his orange Steelman bicycle.

The cycling outfit is described as a black bike helmet, amber colored Smith sunglasses, a white/red/and blue or black long sleeve cycling jersey and long pants. He wears Adidas cycling shoes. His bike had blue Look pedals, a pump, and two water bottles.

This is the bike he ditched on March 1st. A 1996 vintage orange Steelman Stage Race 56cm. snapshot of from 2 April 2002

Nice but late.

“But there is no honor in elegantly proving a theorem in 1672 that some Scotsman proved barbarously in 1671!”

“Meaning what? That you’ve become used to preserving your faith despite being surrounded by heretics?” “No. Rather, it’s as if I’ve got an Amsterdam inside of my head.” “A what !?” “Many different sects and faiths that are always arguing with one another. A Babel of religious disputation that never dies down. I have got used to it.”
