Animated TreeMaps in R - the hard way

As I am a bear of very little brain, these are notes to myself on my slightly shonky process for creating animated TreeMaps in R. The aim is to end up with something like this:

Getting the data is left as an exercise for the reader (sorry!). This loops through the data and generates a separate image for each TreeMa

Lore of the Wild - a musical walk through the woods

Into the woods, it's time to go, I hate to leave, I have to go. Into the woods, it's time, and so I must begin my journey.

I live near the ancient Abbey Woods. Site of the derelict Lesnes Abbey, full of flowers, trees, and eternal mysteries. A tattered parchment map fluttered into my hand promising adventure an

Removing features is a shitty move

I've worked on some big product launches. Every time there's a major update, developers have to think about which features to port over and which to drop.

Sometimes it is easy. Analytics show no one is using this feature? Drop it.

Sometimes it is hard. It's a moderately well used feature, but complicated to get running on a new environment. If you

Gendered 2nd Person Pronouns

English is a stupid, irregular language. But at least it doesn't needlessly ascribe gender to inanimate objects. However, I think this is a weakness when using 2nd Person pronouns - especially in fiction.

Most literature is written in the 1st person ("I opened the door") or the 3rd person ("She picked up a fork"). But very occasionally, mostly in interacti

One of the frustrating things about computers is their limited input options. A "standard" PC keyboard only has about 100 keys. Sure, some have some bonus buttons for controlling the machine, but it is becoming clear that there simply aren't enough buttons to efficiently program computers.

Most programming languages have the concept of relational operators. How does

Movie Review: Marriage Story

ACTORS! ACTING!

Here's a quick summary of the film:

"I AM ACTING!"
"YEAH! WELL I AM ACTING LOUDER THAN YOU!"
"OH? REALLY? JUST LOOK HOW GOOD I'M ACTING!"

It's a relentless argument between two gormless gargoyles. Yes, the director is very clever in using lots of long and unedited shots. And, gosh, isn't the aspect ratio quirky?! Hey, isn't that... you know... the actor

Movie Review: TENET

What if Red Dwarf were given a big budget and re-made "Backwards"?

I'm only teasing a little bit! It is impossible to do a good Time Travel story. The closest I've experienced is "This Is How You Lose the Time War" which, similar to TENET, has sort-of-spies chasing each other through time.

How not to do coding examples

As part of my MSc, I'm getting a few lessons in technologies I'm not familiar with. I've found some of these lessons extremely confusing - even when I'm proficient in the language.

Here's an example of a coding fragment from one of the tutorials in the R language. Let me explain everything that I think is wrong with it.

The follow-but-mute antipattern

I received a rather distraught DM from a Twitter friend last week. They were upset that I was following an account which did nothing but spew out racist bile all day long. Did this mean that I endorsed their hateful views.

I was confused. I didn't recognise the specific account, and didn't recall seeing any of their tweets - but I was following them. How?

What are “unusual characters”

The world is a complex place. It is tempting to enforce simplicity upon it to make things easier for computers. Gender is a boolean, no one is older than 99, all text flows left to right, and names are always in English. That makes it nice and easy for us to write computer systems - and who cares if it is dehumanising?

Recently, I tried to register with phon

I wondered - if it was possible to create a similar clock using books from a single author? So here's my first attempt - using Agatha Christie's novels.

I've tried to use first edition covers, where possible. There are a few notable absences - 8, 9, and 11.
