mazsa··on Ur/web: pure functional, statically typed web programming
"I know of only one "provably correct" web-application language: UR. A Ur-program that "goes through the compiler" is guaranteed not to:

Suffer from any kinds of code-injection attacks

Return invalid HTML

Contain dead intra-application links

Have mismatches between HTML forms and the fields expected by their handlers

Include client-side code that makes incorrect assumptions about the "AJAX"-style services that the remote web server provides

Attempt invalid SQL queries

Use improper marshaling or unmarshaling in communication with SQL databases or between browsers and web servers"

mazsa··on Homotopy Type Theory: Univalent Foundations of Mathematics [Book]
"About the book

Homotopy type theory is a new branch of mathematics that combines aspects of several different fields in a surprising way. It is based on a recently discovered connection between homotopy theory and type theory. It touches on topics as seemingly distant as the homotopy groups of spheres, the algorithms for type checking, and the definition of weak ∞-groupoids. Homotopy type theory offers a new “univalent” foundation of mathematics, in which a central role is played by Voevodsky’s univalence axiom and higher inductive types. The present book is intended as a first systematic exposition of the basics of univalent foundations, and a collection of examples of this new style of reasoning — but without requiring the reader to know or learn any formal logic, or to use any computer proof assistant. We believe that univalent foundations will eventually become a viable alternative to set theory as the “implicit foundation” for the unformalized mathematics done by most mathematicians."

mazsa··on Approaching the Limit of Predictability in Human Mobility
"In this study we analyze the travel patterns of 500,000 individuals in Cote d'Ivoire using mobile phone call data records. By measuring the uncertainties of movements using entropy, considering both the frequencies and temporal correlations of individual trajectories, we find that the theoretical maximum predictability is as high as 88%. To verify whether such a theoretical limit can be approached, we implement a series of Markov chain (MC) based models to predict the actual locations visited by each user. Results show that MC models can produce a prediction accuracy of 87% for stationary trajectories and 95% for non-stationary trajectories. Our findings indicate that human mobility is highly dependent on historical behaviors, and that the maximum predictability is not only a fundamental theoretical limit for potential predictive power, but also an approachable target for actual prediction accuracy."
mazsa··on Did Modern Jews Originate in Italy?
"As reported online today in Nature Communications, more than 80% of Ashkenazi mtDNAs had their origins thousands of years ago in Western Europe, during or before Biblical times—and in some cases even before farming came to that part of the continent some 7500 years ago. The closest matches were with mtDNAs from people who today live in and around Italy. The results imply that the Jews can trace their heritage to women who had lived in Europe at that time. Very few Ashkenazi mtDNAs could be traced to the Middle East.

The results [...] conflict [...] with widespread assumptions about Jewish identity. Jews have traditionally considered that the mother determines the ethnic identity of her children. If being Jewish is defined as genetically descending from the Israelites through the maternal line, then many Ashkenazi Jews fail the test, according to this data."

mazsa··on Mathematicians Predict the Future With Data From the Past
FYI: "Yesterday Wired published an article by Klint Finley, Mathematicians Predict the Future With Data From the Past. Apart from a couple of minor details Klint does a good job explaining the goals and the methods of Cliodynamics. However, he (or his editor; it is almost always editors who come up with titles) couldn’t resist injecting a bit of sensationalism by implying that Cliodynamics can predict the future. I don’t blame him – it’s part of the business they are in. But here, in my blog, where I have no editors over me and nothing to sell, I want to make it absolutely clear that CLIODYNAMICS IS NOT ABOUT PREDICTING THE FUTURE!
