I remember experimenting with doing regressions in Python using R-style formulae a long time ago, and I remember it being a bit complicated. Luckily it’s become really easy now – and I’ll show you just how easy. Before running this you will need to install the pandas, statsmodels and patsy packages. If you’re using conda […]
This is just a very brief reminder about something you might run into when you’re trying to get your code to work on multiple platforms – in this case, OS X, Linux and Windows. Basically: file names/paths are case-sensitive on Linux, but not on OS X or Windows. Therefore, you could have some Python code […]
This is a quick post to brief describe a problem I ran into the other day when trying to debug someone’s code – the answer may be entirely obvious to you, but it took me a while to work out, so I thought I’d document it here. The problem that I was called over to […]
A key – but challenging – part of learning to program is moving from writing technically-correct code ‘that works’ to writing high-quality code that is sensibly decomposed into functions, generically-applicable and generally ‘good’. Indeed, you could say that this is exactly what Software Carpentry is about – taking you from someone bodging together a few […]
I use data from the AERONET network of sun photometers a lot in my work, and do a lot of processing of the data in Python. As part of this I usually want to load the data into pandas – but because of the format of the data, it’s not quite as simple as it […]
I now use Anaconda as my primary Python distribution – and my company have also adopted it for use on all of their developer machines as well as their servers – so I like to think I’m a relatively knowledgeable user. However, the other day I came across a wonderful feature that I’d never known about […]
I’m supervising an MSc student for her thesis this summer, and the work she’s doing with me is going to involve a fair amount of programming, in the context of remote sensing & GIS processing. She’s got experience programming in IDL from a programming course during the taught part of her Masters, but has no […]
Jupyter (formerly known as IPython) notebooks are great – but have you ever accidentally deleted a cell that contained a really important function that you want to keep? Well, this post might help you get it back. So, imagine you have a notebook with the following code: and then you accidentally delete the top cell, with […]
Another instalment in my Previously Unpublicised Code series…this time RPiNDVI, my code for displaying live NDVI images from the Raspberry Pi NoIR camera. It isn’t perfect, and it isn’t finished – but it does the job as a proof-of-concept. If you point the camera out of your window you should see high NDVI values (white) […]
I wrote my PhD thesis in LaTeX, and stored all of the files in my Dropbox folder. Dropbox stores previous versions of your files – for up to 30 days if you are on their free plan. Towards the end of my PhD, I realised that I could write a fairly simple Python script that […]
