## Phyphox

I normally don’t promote external sites or apps on this blog, but I’ve found an app that every nerd needs (I assume here for a moment that you, my reader, might just as well be one). You need to have *Phyphox* on your phone! I need…

*Phyphox* on your phone! I need…

In this article, I list basic scripts to save and load images. As always, I’ve assumed that you want to use *NumPy* and *SciPy* for processing your data, and that you use floating point numbers for all processing and…

Each time I need to do something with audio, one dimensional signal processing in general, or images, I need to go through my collection of Python scripts to help me remember once again which library to use to save and load them. To make this easier…

After deciding that I’d like to automate a weekly tweet of one of my existing blog post, to keep you entertained a bit more now that my posting frequency has diminished lately, I started by googling the different tools and platforms that can be used to do that. However…

Now that we are just past *Pi Approximation Day* (22/7 or July 22), I thought about how to find other fractional approximations of pi with small numerators and denominators. I decided that I was going to *brute force* this thing, just because I can…

Quite a while ago, I decided to do all my Python programming in Python 3 as much as possible. This is essentially always for the typically small stand-alone programs that I put on this blog. I did this to encourage people to use Python 3 for their own work, and to be future proof. Additionally…

This article shows how “old style” linear regression looks when implemented with TensorFlow. When you start diving into TensorFlow, an example like this is typically missing from the tutorials. Linear regression is often the first example, but…

Yes, you can do symbolic math in Python! The library to take a look at is *SymPy*. This article is not a SymPy tutorial, as I only want to walk you through some examples to show you the kinds of things that it can do. A good place to start…

*Turtle graphics* are a way of drawing where you control a *cursor*, known as the “*turtle*”, by instructing it how to move. For example, you tell the turtle to move forward over a certain distance, drawing a line on your screen in the process, then…

To close the series of articles on how to compute fractals using NumPy array operations, I want to show you one more thing: how to create animated GIFs from those NumPy arrays. The first point to make is that…
