##### Pydon't unpack with slices

How should you unpack a list or a tuple into the first element and then the rest? Pydon't unpack with slices, prefer starred assignment instead.

##### Pydon't disrespect the Zen of Python

The "Zen of Python" is the set of guidelines that show up in your screen if you import this. If you have never read them before, read them now and again from time to time. If you are looking to write Pythonic code, write code that abides by the Zen of Python.

##### Pydon't Manifesto

"Pydon'ts" are short, to-the-point, meaningful Python programming tips. A Pydon't is something you should not do when programming in Python. In general, following a Pydon't will make you write more Pythonic code.

##### Implementing an interpreter in 14 lines of Python.

In this blog post I'll show you how you can write a full interpreter for the brainf*ck programming language in just 14 lines of Python. Be prepared, however, to see some unconventional Python code!

##### Let's build a simple interpreter for APL - part 3 - the array model

In this blog post we will go over some significant changes, from implementing APL's array model to introducing dyadic operators!

##### My two cents on the 2020 APL competition

The 2020 APL programming competition was tough! In this post I share a couple of thoughts and my solutions.

##### YAMLUtils: automating boring stuff with Python

If there's one thing I like about Python is how I can use it to automate boring tasks for me. Today I used it to help me manage my own blog!

##### Studying the "24 Game"

The 24 Game is a well-known maths game that is played with kids in school to help them master the four basic arithmetic operations. In this blog post we will study the game in depth.

##### Let's build a simple interpreter for APL - part 2

Today is the day! Today is the day we take our APL programs and interpret them, so that something like ÷ 1 2 3 -⍨ 1.1 2.2 3.3 can output 10 5 3.33333333.

##### Let's build a simple interpreter for APL - part 1

Let's build a simple APL interpreter! APL is an array-oriented programming language I picked up recently. The ease with which I can write code related to mathematics, its strange built-ins (which look like ⍴, ⍨, ⍒ or ⍣) and the fact that it is executed from right to left make it a fresh learning experience!

##### Solving mazes with programming

I have always loved solving mazes... so naturally I had to write a program to solve mazes for me!

258
##### HueHue: a colourful game

HueHue is a very colourful game I wrote with my colleague @inesfmarques.

##### Water buckets riddle

Can you measure exactly $$2$$L of water with two plain buckets with volumes of $$14$$L and $$5$$L? Of course you can!

210
##### Solving diophantine equations with random walks

Here's how I like to solve my equations: just walk around randomly until I trip over a solution!

228
##### Random walk simulations in 2D

Think of a drunk man that continuously tumbles left and right, back and forth, with no final destination.

Progress is great and new things are always exciting... but that doesn't mean old things don't have any value!

##### Fractals and the filled Julia set

The filled Julia set is a really cool fractal that kind of resembles the Mandelbrot set!

539
##### Creating a programming language from scratch

This blog post tells the short story of how I wrote a simple interpreter for a toy programming language!

845
##### Fractals and the Mandelbrot set

I have always liked the concept of fractal. They are very beautiful, they have a notion of infinity embedded in them, and they make no sense (seriously though, self-similarity?). How could they not be loved?

##### Pigeon Pooping Simulator

This blog post has a single purpose, which is to show you the weird game I made, inspired by Flappy Bird and my crazy English teacher.
