Tax Enforcement

how you can get a modicum of tax revenue in a cash-only society. take note, italy / greece.

China has crowdsourced tax enforcement, by potentially rewarding citizens with a cash reward for asking for all of their tax pre-payment receipts, and using them up by scratching off the prize areas. The cost of this massive force multiplier is vanishingly small, as all they are offering is the chance to win; I have only ever seen one winning ticket in the past couple of years, and it was for about 2 kuai. Still, it is a nice cultural touch to the end of a big meal, everyone sitting in a circle, scratching their fapiao to see if they won a prize for playing the part of a Chinese tax enforcement agent.

Nicolas Bourbaki

In 1934, André Weil and Henri Cartan, both young professors of mathematics at the University of Strasbourg, would frequently, when discussing the calculus courses, they were teaching, deplore the textbooks available, all of which they considered antiquated and inadequate. Weil eventually suggested getting in touch with several of their fellow alumni of the École Normale Supérieure who were teaching similar courses in provincial universities around France, inviting them to collaborate on a new analysis textbook. The complete work was expected to total 1000 to 1200 pages, with the first volumes ready about 6 months after the project began. Thus began 1 of the most flabbergasting examples of “mission creep” in human intellectual history, which set the style for much of mathematics publication and education in subsequent decades. Working collectively and publishing under the pseudonym “Nicolas Bourbaki” (after the French general in the Franco-Prussian War Charles Denis Bourbaki), the “analysis textbook” to be assembled by a small group over a few years grew into a project spanning more than 60 years and 10 books, most of multiple volumes, totaling more than 7000 pages, systematizing the core of mathematics in a relentlessly abstract and austere axiomatic form. Although Bourbaki introduced new terminology, some of which has become commonplace, there is no new mathematics in the work: it is a presentation of pre-existing mathematical work as a pedagogical tool and toolbox for research mathematicians. (This is not to say that the participants in the Bourbaki project did not do original work—in fact, they were among the leaders in mathematical research in their respective generations. But their work on the Bourbaki opus was a codification and grand unification of the disparate branches of mathematics into a coherent whole. In fact, so important was the idea that mathematics was a unified tree rooted in set theory that the Bourbaki group always used the word mathématique, not mathématiques.)

Craigslist Robbery

“I came across the ad that was for a prevailing wage job for $28.50 an hour,” said Mike, who saw a Craigslist ad last week looking for workers for a road maintenance project in Monroe. He said he inquired and was e-mailed back with instructions to meet near the Bank of America in Monroe at 11:00 Tuesday. He also was told to wear certain work clothing. “Yellow vest, safety goggles, a respirator mask… and, if possible, a blue shirt”. Mike showed up along with 10 other men dressed like him, but there was no contractor and no road work to be done. He thought they had been stood up until he heard about the bank robbery and the suspect who wore the same attire.

Mapmaker Review

Google MapMaker is out. There are several geowiki projects, but when someone like google decides to have a go at the problem you have to take notice. First thing to note is that the MapMaker is open for a limited set of countries, one of which I have blogged about earlier. So let’s see what the uptake of MapMaker is by looking at Karachi (a city of ~20million, metropolitan and where locals are cultured with a strong entrepreneurial spirit) it appears there is very fast uptake from the locals. Here is what has happened in the course of a few hours
