1:30PM - Quote of the Day.

But it was her eyes that stopped his breath; that made his heart leap up. Blue they were, even through the swirling vapors of pompous Chesterfields and arrogant Lucky Strikes he saw her eyes were a blue beyond blue, like the ocean. A blue he could swim into forever and never miss a fire engine red or a cornstalk yellow. Across the chasm of that room, that blue, those eyes, devoured him and looked past him and never saw him and never would, of that he was sure. From that moment, Eugene understood what the poets had been writing about these many years, all the lost, wandering, lonely souls who were now his brothers. He knew a love that would never be his. So quickly did he fall for her that no one in the room even heard the sound, the whoosh as he fell, the clatter of his broken heart. It was a sure silence, but his life was shattered."

Genius. Script by John Logan.

12:58PM - Quote of the Day: too many books

The high prices limited the market to persons of means. However, princes and nobles at first scorned the books produced in quantities and continued to purchase only manuscript copies. The clergy and the lawyers were less reluctant to accept substitute for manuscripts.

But the rapidity with which books came off the presses soon caused a glut on the market, because the reading public was not yet used to the idea that it could afford to buy more books. After eight years of hard, steady work, Sweynheym and Pannartz were caught in the first depression of the book trade with no cash and with all their funds tied up in a large stock of unbound copies. They implored Pope Sixtus IV to aid them, listing their inventory of 12,475 books. They complained that this accumulation crowded their quarters, so that they could scarcely move and even had to beg for their daily bread.

In the 1960s, there was a similar event in Silicon Valley during the microwave boom and bust cycle when the military suddenly reduced its purchases of radar-related equipment.

In the 1920s, the first bread slicing machines had a similar problem.

2:43PM - TIL

Mothers and sugars are the primary sources of caries–inducing bacteria in children:

Earlier studies suggest that infants acquire mutans streptococci (MS) from their mothers and only after the eruption of primary teeth. [49],[50] Preventive interventions for the purpose of reducing the transmission of bacteria from mothers to children improve the likelihood of better oral health for the child.

12:15PM - Quote of the Day: Babylonian System A

It cannot be overemphasized that System A had no analogous precursor, and thus that – unlike virtually all succeeding scientific theories – its invention was a radical departure from anything which preceded it. Consequently, we can say almost nothing with confidence about its motivation, which cannot have been directed at the shortcomings of a (non-existent) prevailing theory, nor seemingly at any urgent practical need, since we have still no evidence of how it was employed. Indeed, how little we know of the circumstances of its origin is reflected in the fact that we do not even know for certain its author’s name.
The crucial step – apart from conceiving the desirability and imagining the feasibility of constructing a comprehensive mathematical model of this complex set of variable phenomena – was the separation and successful modeling of the effects of lunar and solar anomaly on the intervals between syzygies. The crux of this development was the initial construction of a model depicting the variations due to lunar anomaly of the intervals between syzygies.
One of the fundamental tools of Babylonian astronomy was the concept of period relation which equated Π phenomena of one sort with Z of another.
In each case the period relation implied that variations associated with the second phenomenon recurred after Π instances of the first phenomenon, and thus that Π phenomena = Z cycles of variation.

11:27AM - the Duck-Rabbit as a pullback

118. In my remarks, the following figure, derived from Jastrow, will be called “the duck–rabbit”. It can be seen as a rabbit’s head or as a duck’s.

And I must distinguish between the ‘continuous seeing’ of an aspect and an aspect’s ‘lighting up’.
The picture might have been shown me, without my ever seeing in it anything but a rabbit.

Remarkably, the picture is a pullback, while the experience is a pushout.

10:35PM - A posteriori

The notion that an economically mature technology can be modeled as a free monoid is trivial because the technology is going to be completely described and communicated by standardized instructions (mechanical, logical, verbal, etc.), wherein the instructions are concatenated sentences from a specialized dictionary.

The good news is that when we have an inkling of a promising idea we can imagine how it is going to look like when fully matured. The bad news is that there's no dictionary yet to imagine it from.

3:36PM - The women invasion!

... the fastest-growing jobs are dominated by women, while the fastest-shrinking ones are predominately male.
Men’s movement into low-skilled women’s jobs since 2000 is partly a result of the hollowing out of middle-skill jobs in fields like clerical and manufacturing work, which was described by the economist David Autor. Women were hit harder — female employment in those jobs fell 16 percent from 1979 to 2007, compared with 7 percent for men. But women almost uniformly moved into high-skill jobs, while men were more likely to move into low-skill, low-paying jobs.


Trump voters must feel really threatened by women.

Вчера на лекции по Конфессиям Святого Аугустина вдруг понял, откуда растут гендерные роли. Потом, по дороге домой мне встретился енот, и я сразу все забыл.

У Святого Аугустина очень хорошо описывается переход из одного моноида в другой. В условиях поздней римской империи стало невозможно добывать и накапливать virtus, как это происходило в традиционной культуре. Его просто не из чего стало делать. Поэтому Аугустин переопределил vertus и принял другой способ его создания.

Где-то в середине занятия профессор сделал интересны мысленный эксперимент. Он представил себе встречу Катона-старшего с Аугустином и их разговор о смысле vertus. Разговор бы не получился, потому что для Катона рассуждения Аугустина звучали бы бессмыслицей.

Теперь представьте себе, что вас несколько тысячелетий с детских лет учат быть хорошей девочкой-помощницей и многодетной мамой. Если вам не очень повезет, то вы умрете при родах. Если повезет, то из многодетной мамы вы превратитесь в бабушку и продолжите учить девочек быть хорошими многодетными мамами.

Прокручиваем время вперед: в середине 20-го века произошла демографическая революция и бабушкой вы не станете. А раз не станете бабушкой, то учиться быть хорошей девочкой и многодетной мамой тоже несколько теряет смысл. Вот тут и приходит момент Святого Аугустина, когда надо переходить в другую веру.

5:26PM - Расползание лихорадки

Смотрите, какую я authentic карту нашел. В левом верхнем углу Ленин со Сталиным. Троцкого к тому времени уже изъяли из истории.

10:36AM - Больше? Лучше!

Закончил читать курс, билеты и гостиница заказаны - время уезжать на рабочие каникулы.

Курс получился интересный, даже самому понравилось. Правда, из теории категорий ничего не вставил, потому что сам еще не совсем разобрался. Например, пару дней назад до меня дошло, что многие из моих разнообразных стрелок и пулбэков/пушаутов можно заменить элементарным изоморфизмом между отрезком и сегментом дуги: | -> ) Фокус в том, чтобы подобрать три правильных измерения: одно для отрезка и два для дуги. Пока не понятно, как это все соотносится с идеями применения моноида. Похоже, что свободный моноид - это категория, которую можно отобразить функтором на отрезок, причем в моноиде есть какой-то встроенный предел, не позволяющий выйти за границы отрезка в определенном измерении. M -> | -> )

Надо подумать и попробовать применить, например, к переходу от схимников к монастырям и т.д.

7:45PM - Does it work?

Enter Hamlet.

1:42PM - Oops!

In a statement on Thursday, Amazon said an employee on its S3 team was working on an issue with the billing system and meant to take a small number of servers offline -- but they incorrectly entered the command and removed a much larger set of servers.
According to Synergy Research Group, AWS owns 40% of the cloud services market, meaning it's responsible for the operability of large swaths of popular websites.


9:53AM - Анекдот продолжается

В администрацию Трампа опять ввели козу.

“I’m not aware of any of those activities,” he responded. He added: “I have been called a surrogate at a time or two in that campaign and I did not have communications with the Russians.”
