## Mathpix Snip

I came across this amazing tool that can convert images of math equations into LaTeX format. The tool can be found at https://mathpix.com/. I’ve tried on a number of texts including some not so clear and it does a fantastic … Continue reading

## Marsaglia’s MWC (multiply with carry) Random Number Generator for Object Pascal

In the past, I’ve tended to use the Mersenne Twister for generating pseudo-random numbers. This is a widely used generator because it has a very long period of 2^{19937} – 1. The one issue is that it’s not the fastest … Continue reading

## Drawing a Pathway Fragment with Inhibition using Tikz

Here is another quick pathway fragment I needed today. This won’t scale well because I’ve used some fixed dimensions eg the width of the lines and the size of the text. But these are easily adjusted if you want to … Continue reading
