Kalman Filtering Falling Objects

2025-01-04
In this blog we will track a falling object using a Kalman filter. Our goal will be to create a simulation of a falling object, and filter that with the Kalman filter. We'll plot the residuals and see how well we can reconstruct the original signal from the noisey signal. We'll code this in Rust, which is a great choic

In this question we are asked to explore the consequences of assignment, and to write a function f such that evaluating f(0) + f(1) from 0 if evaluated from left to right and 1 if evaluated from right to left.In this question we are working with the following functionWe then defineWhat happens if we compute last_pair(z

Blog Tools 0.1.2

Since the last time I wrote about blog-tools the crate has had quite a bit of development, so I thought now would be a good time to shout out about it.First, the create now comes with three working examples of a blog you can run right away. Simply clone the repo and runWhat do the high, medium and low refer to? That's

In Exercise 14 we are asked to investigate that calculating resistances with the interval arithmatic package we wrote gives different results. We try\[\frac{R_1 R_2}{R_1 + R_2}\]and\[ \frac{1}{1/R_1 + 1/R_2} \]Although these are mathematically the same equation, they produce quite different results with interval arithm

Pass Me a Message

2024-03-16
Some time ago I wrote an article on object orientated programming which I am now not particularly proud of. I think that article was poorly researched, and didn't work adequately to define what "object orientation" is. In this article I want to deeply explore what an "object" is, and what it means t

Object Orientation is a Religion

2024-01-07
I'm currently working on a lengthy article on reason, which is coming along slowly. In the meantime, I thought I'd make a short video on a quip I often say - object orientation is a religion. Now, this might seem a little abstract so I wanted to break it down for a while. Thankfully, the perfect opportunity presented i

Using blog-tools

2023-08-26
A few months ago, I wrote an article on making a blog in Rust. Since then, this idea has had quite a bit of development. I needed to make blogs at work too. This was a good opportunity to improve the code. One thing lead to another and eventually I published the blog library on crates.io. You can install this like you

Lifetimes and Ownership in Rust

2022-07-24
Lifetimes and ownership in Rust are some of the aspects of the language users coming from other languages struggle to understand. Few languages have concepts similar to these, so they can be unfamiliar. However, they are by far the most powerful aspects of the language that give Rust its appeal. Through lifetimes and o

How to Refactor

2022-05-22
I recently read the book "Refactoring: Improving the Design of Existing Code" by Martin Fowler. I thought the book was ok, but a little outdated. Generally, the book was a product of its time – while there were some gems of advice present, a lot of the book was dedicated to refactoring procedural code into

Handling Errors in Rust

2022-03-27
Many people who come to Rust for the first time struggle with error handling. There is no concept of the try-catch block as there is in many other languages like Java or Python. How do you handle errors? This is done via four concepts – Result, Option, Unwrap and Match.Result is the core concept of error handling. Si

Why I Hate Object Orientated Programming And What to Use Instead

2022-02-06
Anyone who has began programming over the last few decades has probably been extensively exposed to the concept of "object orientated programming" (I'll refer to it as OO from now on). In fact, most courses in programming or programming textbooks say that OO programming is the correct way to program.Indeed, l

The Joy of Programming

2022-01-16
I program for most of the day at work. Not everyone in the office knows how to program, and to them it could just be magic. Granted, for the most part, they do advertising, marketing and sales, and I don't think I would succeed in those domains at all. Nevertheless, this is about the joy of programming rather than the
