Well funnily enough I started back at what a matrix really is. What does it mean to multiply them, add them, invert them and so on. The first good resource I used was Better Explained! I also took out some Linear Algebra text books from the

Feather is a recently released data frame file that both R and Python can interface with. We have Hadley Whickam and Wes McKinney to thank for it!

Just a heads up: Jupyter Notebook is not an open source alternative to Mathematica. Originally, Jupyter was iPython notebook, an IDE of sorts for data science and analysis in Python, by writing code and markdown together in a more coheren

I'm really impressed you used Julia in production. Despite its immaturity and all the reasons you mentioned, building your product on it is a testament to the language, its potential and the core group working on it. I wonder what the

I've a similar story! Working through the Nature of Code[1] is exactly the point in my life where differential equations and vector algebra suddenly made sense to me. Once I became the 'creator' I could see how this math d

I am never comfortable with my understanding of a topic until I can teach it (or at least pass it on). There's just always an annoying, niggling feeling that if I were to be faced with a student who kept asking "why", I'

The more advanced mathematics I learn, the more I realise that in many cases I do not have a fundamental understanding of many topics, which leads me back to the beginning. More often than not, Better Explained is at the end of that path. I

Look, I'm not planning on printing the whole thing, binding it and sticking it on my shelf. I want the pdf because then I can use it when I'm offline, across devices and search it easily. If I want this book in hard copy, then I w

You're right, that's why we use Gross Domestic Product (GDP) as our primary measure of an economy's performance; which employment is the fundamental driver of. I wasn't arguing against basic income, I was just contending

I think we're hitting the .00001% here. Such a bizarre reality.

I suppose from an individual standpoint examples like yours are very relevant - a big fear for myself is working a job we're I am unfulfilled - but from a broad view we must agree increasing employment is a good goal. The more people w

I agree, this article was disappointing and is attracting the reaction I expected once I finished reading it. Ultimately the author pointed out the minor infrastructure development requirements of EVs, a bizarre point about hauling trailers

If they purchased an option then Virgin paid for it. Optioning purchases is a common instrument traded in aviation finance. The option to buy this aircraft at some point in the future at a price specified today is worth a lot. The fact that

The article first states that they've optioned a purchase - so I assume they've purchased some sort of call option and Boom are the issuers which would mean that some money has changed hands.

The article has nothing to do with how the data is gathered, stored and sometimes used. It's about real-time rendering of elevation maps in the browser. It's really impressive work.

Looks like Hadleyverse is spreading! Honestly, I think his contributions have led the way for R to being the leading language in data science.
