In ordinary arithmetic, the decomposition of a number is finding two numbers that when multiplied together give the original number. For example, the number 12 can be decomposed into 3 and 4 because 3 * 4 = 12. There’s a … Continue reading
Even though I’m not a huge fan of JavaScript, I like the language more than most of my engineering / developer colleagues. Just for fun I decided to code up a function that selects n random integers from N. For … Continue reading
Chess grandmaster Hikaru Nakamura won the 2019 U.S. chess championship with a score of 8.0 out of 11. The event ran from March 18 through April 1 and was held in St. Louis. Nakamura is one of the strongest players … Continue reading
The beta distribution pops up from time to time in my work with machine learning. Many people are familiar with the Gaussian (also called normal, or bell-shaped) distribution. A particular Gaussian distribution is characterized by a mean and a standard … Continue reading
In some programming scenarios it’s useful to get the sort ordering of an array. For example, suppose an array/vector has values [5.5, 3.5, 1.5, 2.5, 4.5]. If you sort the array you’d get [1.5, 2.5, 3.5, 4.5, 5.5]. But instead … Continue reading
My dog is responsible for this blog post. I’ll explain what that means in a moment. The quicksort algorithm is generally considered the best all-purpose technique to sort an array. Most programming languages have a built-in library that has a … Continue reading
I wrote a very lightweight random number generator using JavaScript. Well, it’s not really a RNG, it’s a very crude way to generate sort-of random numbers. I figured I should do a minimal check of the RNG code to make … Continue reading
