This deserved a bit of further explanation, due to the stupidity involved. “Debugging is like being the detective in a crime movie where you are also the murderer.” – Filipe Fortes My code was giving an unexpected result and I was having a hard time figuring out the problem. The unexpected result was that a […]
Do It Yourself: Lab Notebook Archiving Project
A while back, the lab moved to an electronic lab notebook (details here and here). One of the drivers for this move was the huge number of hard copy lab note books that had accumulated in the lab over >10 years. Switching to an ELN solved this problem for the future, but didn’t make the […]
Dividing Line: not so simple division in ctenophores
This wonderful movie has repeatedly popped up into my twitter feed. It was taken by Tessa Montague and is available here (tweet is here). The movie is striking because of the way that cytokinesis starts at one side and moves to the other. Most model systems for cell division have symmetrical division. Rob de Bruin […]
Frankly, Mr. Shankly
I read about Antonio Sánchez Chinchón’s clever approach to use the Travelling Salesperson algorithm to generate some math-art in R. The follow up was even nicer in my opinion, Pencil Scribbles. The subject was Boris Karloff as the monster in Frankenstein. I was interested in running the code (available here and here), so I thought I’d […]
Paintball’s Coming Home: generating Damien Hirst spot paintings
A few days ago, I read an article about Damien Hirst’s new spot paintings. I’d forgotten how regular the spots were in the original spot paintings from the 1990s (examples are on his page here). It made me think that these paintings could be randomly generated and so I wrote a quick piece of code […]
Scoop: some practical advice
So quantixed occasionally gets correspondence from other researchers asking for advice. A recent email came from someone who had been “scooped”. What should they do? Before we get into this topic we have to define what we mean by being scooped. In the most straightforward sense being scooped means that an article appeared online before […]
Measured Steps: Garmin step adjustment algorithm
I recently got a new GPS running watch, a Garmin Fēnix 5. As well as tracking runs, cycling and swimming, it does “activity tracking” – number of steps taken in a day, sleep, and so on. The step goals are set to move automatically and I wondered how it worked. With a quick number crunch, […]
Esoteric Circle
Many projects in the lab involve quantifying circular objects. Microtubules, vesicles and so on are approximately circular in cross section. This quick post is about how to find the diameter of these objects using a computer. So how do you measure the diameter of an object that is approximately circular? Well, if it was circular […]
Inspiration Information: some book recommendations for kids
As with children’s toys and clothes, books aimed at children tend to be targeted in a gender-stereotyped way. This is a bit depressing. While books about princesses can be inspirational to young girls – if the protagonist decides to give it all up and have a career as a medic instead (the plot to Zog […]
In a Word: LaTeX to Word and vice versa
Here’s a quick tech tip. We’ve been writing papers in TeX recently, using Overleaf as a way to write collaboratively. This works great but sometimes, a Word file is required by the publisher. So how do you convert from one to the other quickly and with the least hassle? If you Google this question (as […]
