I recently read this book review [0] where a mathematical proof was described as a dialogue between two semi-adversarial but collaborative actors, the Prover and the Skeptic, who together aim to aquire mathematical insight. I thought it was

Good point on the benefits of reading bad code. One of the best developers I've worked with said he'd become a good developer by refactoring a lot of bad code.

I'd add to that and say shorting is typically selling a share that you don't own. Which means you need to borrow it from a broker for a fee. There's a securities lending market which revolves around borrowing and lending shar

That was my first year text book in 1998. Sounds like it's still going strong!

Agreed, my experience programming has been similar. Simply put the hardest part of most big software projects is just building the right thing.

Yes, I was in first year in 1998 and only learnt to program then. My career has involved working as a programmer or in roles that required me to do significant amounts of programming.

I completely appreciate that. I was also attempting to tell regular excel users about the virtues of TDD! I had grander plans where I imagined creating centralised test suites that caught more generic issues and anybody in the bank could up

I've built a unit testing framework for Excel using Python and the openpyxl library. I work in a bank and using Excel was unavoidable in some cases. You'd basically build a test suite for a spreadsheet in Python and run it like a

If you did write a paper that assumed different axioms to the norm you would just state that you had done so! Because mathematics is axiomatic, mathematicians are happy to play around with axioms as long as it leads to something interesting

I agree with that. I've been programming on and off in Python since 2008 and really like the language. I started using R just over a year ago after joining a new team. It took a while to adjust but I've gotten to prefer it for exp

I found learning about the binomial model to be particularly good at establishing intuition about option pricing. Nowadays it's considered a toy model but it makes the ideas of a replicating portfolio and risk neutral probabilities ver

Haskell course in 3rd year at university in the year 2000. It was only 5 weeks and I didn't fully appreciate it at the time. I did maths for a few years after that and only returned to programming later and rediscovered functional prog

Given that in the UK a degree is 3 years and an MSc is typically 1 year, I would do an MSc. Delaying work by one year isn't much in the grander scheme of things. Once you've started working you'll find it hard to come back an

I was expecting you to say finance where Excel is abused in a similar fashion!

In my previous job I used a Python library called openpyxl to write a suite of unit tests for some unwieldy spreadsheets that our team owned. The tests were run every time the sheets were updated so we had a form of test driven development

Yes, my younger sister plays wordle and we send each other our results. We normally exchange a few messages off the back of it while previously we communicated more sporadically. It's been a nice part of my daily routine, but I&#x27

Not a book, but the podcast Without Fail discusses these sort of stories. It's by Alex Blumberg the same person who did the Start Up podcast.

@author - is there anything special about the way you visualize prime numbers? I'm wondering if there are indicators for you that a given number would be prime.

I normally ask candidates to produce a frequency count of the elements in a list. My ideal solution is that they use a dictionary to do it in O(n) time.
