Hi, I'm Fuzzy.
This site, Fuzzy's Logic, is a dumping ground for things I find interesting. If you're looking for content I've personally generated you might want to head directly to one of my other sites:
Statistics 110 (Probability) has been taught at Harvard University by Joe Blitzstein (Professor of the Practice in Statistics, Harvard University) each year since 2006. The on-campus Stat 110 course has grown from 80 students to over 300 students per year in that time. Lecture videos, review materials, and over 250 practice problems with detailed solutions are provided. This course is an introduction to probability as a language and set of tools for understanding statistics, science, risk, and randomness. The ideas and methods are useful in statistics, science, engineering, economics, finance, and everyday life. Topics include the following. Basics: sample spaces and events, conditioning, Bayes' Theorem. Random variables and their distributions: distributions, moment generating functions, expectation, variance, covariance, correlation, conditional expectation. Univariate distributions: Normal, t, Binomial, Negative Binomial, Poisson, Beta, Gamma. Multivariate distributions: joint, conditional, and marginal distributions, independence, transformations, Multinomial, Multivariate Normal. Limit theorems: law of large numbers, central limit theorem. Markov chains: transition probabilities, stationary distributions, reversibility, convergence. Prerequisite: single variable calculus, familiarity with matrices
The Data Analysis learning path provides a short but intensive introduction to the field of data analysis. The path is divided into three parts. In part 1, we learn general programming practices (software design, version control) and tools (python, sql, unix, and Git). In part 2, we learn R and focus more narrowly on data analysis, studying statistical techniques, machine learning, and presentation of findings. Part 3 includes a choice of elective topics: visualization, social network analysis, and big data (Hadoop and MapReduce). Choose from any or all of them to enrich your understanding and skills. "
After a 5 year hiatus, acclaimed a16z investor and netscape founder Marc Andreessen returned to twitter (@pmarca) in '14 to give his point of view on the topics of entrepreneurship, investing, politics, and economics. Unfortunately spread over multiple tweets, known as tweetstorms, which are hard to follow using the default twitter timeline. Luckily recently Marc started to use the 'reply to' feature, which allows my algorithm to group the tweets together to improve readability.

Told by the six-foot, five-and-a-half-inch Russinovich in his wonderfully straightforward way, it's a tale that lays bare the unapologetically ruthless attitude that pervaded Microsoft in the '90s and on into the aughts, an attitude that brought it enormous success but also landed the company in hot water with regulators and ultimately hampered its ability to compete in the more open and collaborative world of the modern internet. But the postscript to the tale-where Jim Alchin, the head of Windows, tries to hire Russinovich-also shows that Microsoft is more complicated than you might expect, that the company is capable of change, however long that change might take.
In the past 40 years, space flight has encountered all sorts of failure modes. Propulsion systems have leaked and exploded. Power systems have short-circuited. Observation instruments have failed to work or have been pointed in wrong directions. But until this year no CFIT had occurred in outer space.Then, on 23 September, through a series of still-baffling errors, flight controllers at the Jet Propulsion Laboratory, a California Institute of Technology facility under contract to NASA, sent erroneous steering commands to the Mars Climate Observer as it neared the target planet. Obeying blindly like all true robots, the probe, metaphorically speaking, marched off the cliff and was destroyed.
Airports are known for rules and regulations, a reputation that applies to the runways as well. Almost all airport designs are governed by regulations established by the International Civil Aviation Organization to ensure pilots circling Toledo or Timbuktu remain properly oriented and deliver passengers and cargo safely.Lauren O'Neil turns those strictures into art, with the help of Google Earth. The Brooklyn-based designer has made a meticulous study of airport runways and logged the results on a Tumblr called Holding Pattern. These views reveal beautiful compositions at airports that are nothing special at ground level.
This was the problem with virtual reality. It couldn't just be really good. It had to be perfect. In a traditional videogame, too much latency is annoying--you push a button and by the time your action registers onscreen you're already dead. But with virtual reality, it's nauseating. If you turn your head and the image on the screen that's inches from your eyes doesn't adjust instantaneously, your visual system conflicts with your vestibular system, and you get sick.There were a million little problems like that, tiny technical details that would need to be solved if virtual reality were ever to become more than a futurist's fantasy. The Rift had made enough headway to excite long-suffering VR enthusiasts, but it was still a long way from where it needed to be.
Economics of Poker: The Effect of Systemic Chance" (2012) by Robert Hannum, a professor of risk analysis and gaming at the University of Denver. His study of more than a billion hands of online Texas Hold'em found that 85.2 percent of the hands were decided without a show of cards. In other words, players' betting decisions were of overwhelming importance in determining the outcome. Of the remaining 14.8 percent, almost half were won by a player who didn't hold the best hand but instead had induced the player with the best hand to fold before the showdown.Hannum concluded: "Clearly the driving force behind the economic outcome of Texas Hold'em is skill rather than chance.
