6 Things You Probably Didn’t Know About Pi Today is Pi Day. You know, March 14. 3/14 is sort of like 3.14. Get it? OK, it’s a bit of a stretch because 3/14 looks like a fraction and not Pi. Whatever. Even if the date of Pi Day is a little weird, Pi is still pretty awesome. There are many approximations for Pi If you have a circle, you can measure two things: the distance around the perimeter of the circle (circumference) and the distance across the widest part of the circle (diameter). The simplest approximation for Pi is just 3. The early history of mathematics covers many approximations of the value of Pi. You can calculate a bunch of digits of Pi There are many methods to calculate Pi but I will go over the simplest to understand. The basic idea behind the Taylor Series is that any function sort of looks like a power series if you just focus on one part of that function. Expanding this function about the point x = 1 should be equal to π/4. That’s it. See, that’s not so difficult for a computer. OK, here is the program. Homework
The Effect of Video Games on the Brain Biology 2022004 First Web Paper On Serendip Eleni Kardaras The effect of video games on the brain is a research area gaining popularity as the percentage of children and adults who play video games is on the rise. Some people believe violence in video games and in other media promotes violent behavior among viewers. I had a chance to observe the effects of video games first hand on two boys, ages eight and ten, when I babysat them earlier in the semester. Akio Mori, a professor at Tokyo's Nihon University, conducted a recent study observing the effects of video games on brain activity. Perhaps looking at what effects video games have on autonomic nerves can begin to answer that question. From the above studies and observations, video games do effect the players in some ways, since it appears that players get so wrapped up in the game that they forget their surroundings and begin to see the game as a real quest.

Coding for SSDs – Part 1: Introduction and Table of Contents | Code Capsule Introduction I want to make solid-state drives (SSDs) the optimal storage solution for my key-value store project. For that reason, I had to make sure I fully understood how SSDs work, so that I can optimize my hash table implementation to suit their internal characteristics. There is a lot of incomplete and contradictory information out there, and finding trustworthy information about SSDs was not an easy task. Then I figured that since I had done all the research, it would be useful to share the conclusions I had reached. The most remarkable contribution is Part 6, a summary of the whole “Coding for SSDs” article series, that I am sure programmers who are in a rush will appreciate. Another important detail is that “Coding for SSDs” is independent from my key-value store project (IKVS series), and therefore, no prior knowledge of the IKVS articles is needed. My only regret is not to have produced any code of my own to prove that the access patterns I recommend are actually the best.

24.5. turtle — Turtle graphics for Tk — Python 2.7.8 documentation 24.5.1. Introduction Turtle graphics is a popular way for introducing programming to kids. It was part of the original Logo programming language developed by Wally Feurzig and Seymour Papert in 1966. Imagine a robotic turtle starting at (0, 0) in the x-y plane. By combining together these and similar commands, intricate shapes and pictures can easily be drawn. The turtle module is an extended reimplementation of the same-named module from the Python standard distribution up to version Python 2.5. It tries to keep the merits of the old turtle module and to be (nearly) 100% compatible with it. The turtle module provides turtle graphics primitives, in both object-oriented and procedure-oriented ways. The object-oriented interface uses essentially two+two classes: The TurtleScreen class defines graphics windows as a playground for the drawing turtles. The procedural interface provides functions which are derived from the methods of the classes Screen and Turtle. Note 24.5.6. 22.214.171.124. 126.96.36.199.
