It’s hard to balance how much you should write on paper in place of just coding. Coding in itself allows you to explore the problem, but induces its own cognitive overhead, which might distract you from important insights about the directio

Does anyone remember the picture of the guy at the Counter Strike LAN party who was taped to the ceiling, fragging away with belly facing the floor? https://www.kotaku.com.au/2020/06/15-years-later-heres-why-a...

After reading this post and the link there on the ‘Feynman Method’, I’ve decided to read Polya’s ‘How to Solve it’ [1]. I say this as someone who did his BSc in pure mathematics, MSc in CS and has worked as a programmer for a number of year

I've been mostly functional throughout my career, so that method would have appealed to me before. The idea is to never mutate but always create a copy of data to prevent race conditions. Fundamentally though, you are mutating data. We

Reproducibility is great. I would probably employ Docker for that if that were my role. However, this is completely from my own limited personal experience: I've worked with multiple devops people at earlier stage companies who have ha

On the grand scale of things, I don't have that many years of work experience under my belt. What do you think would be the optimal evolution of a company from day 1 would be in this context? Obviously it's all speculation, but I

I like the idea the author mentions of message queues in the database. It also sounds like it would be easier to separate if need be. I also like the idea of keeping everything in a single database as long as possible. Even if it turns out

For a non-blockchain version of this, in Europe there has been an effort towards developing and implementing a system called USEF [1], which allows entities like power stations, speculators and aggregators like British Gas across Europe to

I was convinced for some reason that you need balance on all sides to ensure profit. I don't know how I arrived at this conclusion, as doing the (very simple) maths again, it does indeed seem possible to make a profit on independent la

Everything makes sense now. Thanks.

If I backed the odds which people were laying at, then my bets would match, but I would be losing money in the long run and I would be a sucker. As far as I understand, there are plenty of suckers in the game, but they are mostly backing an

That looks like a nice question, although it looks like I've lost, as I can't figure out what the input represents. Any tips?

Right now no one. Betfair only takes a commission on money that changes hands. As fair as I understand, they are not openly laying or backing bets. Backing is the simplest way of making a bet which ensures positive expected return. That is,

Thanks. Around the time when I first figured out the algorithm, Betfair independently approached me about possibly working with them, and then banned me when I mentioned the algorithm. I’m not really sure whether it was the algorithm, or wh

If anyone’s interested, I figured out a way to compute the exact odds for Betfair’s online Exchange Hi Lo card game [1] in polynomial time and space. Overview at [2], algorithm and explanation of the underlying maths at [3]. I’m quite sure

I don’t have a huge amount of experience writing C++ code. What are these other more efficient ways? I suppose virtual classes is one, but it becomes difficult to add functions.

Testing asymptotic behaviour is quite simple. It can be done empirically. Yes, you might make a formal proof of asymptotic behaviour and the property that the iterator returns a set, given a certain approximate model of the system, of cours

Can you explain the interop a bit more? I’ve been looking into an F# job. Having a functional background, the language looks nice, but I’m wondering about the ecosystem. Can you not use .Net libraries as easily as you can from C#?

How would you implement and test something something like C++'s unordered_set, a set with constant insert and lookup, using type-level constraints instead of unit tests? How would you represent this with types?

I’m spending some time in Constantinople right now, if anyone wants to spend some time lamenting the fall of the Western Roman Empire together. That is, after the weekend plague curfew. Email transitively in profile.
