"Kelly maximizes utility of money modeled as a logarithmic function." Absolutely true, but consider what log utility also creates a decision rule that leads to growth-rate optimization under multiplicative bets. You may find these

This is a great answer. To answer the question about the 3-sided die: the question is flawed for 2 reasons. First, the way you phrased it, you know the information a priori. It's like me learning that the car isn't behind door #1

Cosmos: A Spacetime Odyssey had an episode (#5) called "Hiding in the Light"[1] that contained a fair bit about Joseph Fraunhofer. [1] https://en.wikipedia.org/wiki/Hiding_in_the_Light

"Mr. Moy’s past work, however, that makes his presence among us interesting." I don't know why. He was Director of the US Mint: he printed coins. It's a manufacturing business. It has nothing to do with monetary polic

My sister just released a game early access on Steam[1] called "The Counting Kingdom"[2]. It targets the U.S. core math curriculum for 6-8 year olds. The idea is that by embedding mathematics into the core mechanics of the gamepl

I suppose if your estimator is biased and not consistent -- due to some sort of omitted variable -- you can end up with "significant" estimates that are completely removed from reality. Great explanation at http://eran

Is it possible to set this up so that you can point it to a remote URL to fetch the CSV? For example, I'd love it if I could point it towards a Yahoo! Finance API call that returns a CSV file and have my dashboard auto-update. Or Dro

You might want to check out the "AI Game Programming Wisdom" series. I think at this point, there are four of them. "Game Programming Gems" is another series worth checking out (I think there are 8 at this point); each book normally has a

As I said below, it's likely that I am hyper-sensitive to these issues. I urge you to continue sharing your journey and your stories! Be careful not to take away credit from yourself, though; in finance, your father may have been able to "

As I said, I am likely over-sensitive to these issues; finance isn't exactly the most well-respected industry at the moment.

I am a 20-ish year old and despite "what I do" has been done before, the "way I do it" never has -- and that is plenty "exciting." There is nothing safe or low-risk about starting a hedge fund. I get your point about "having more meaning"

As someone who has started a business in the finance space trying to leverage technology, I take some offense to this. My business partners and I have worked our asses off over the last several years to get to where we are today: billions

I completely agree with this. It's the same issue with comparing MBA programs to accelerator programs. A Masters in Business Administration is NOT a Masters in Entrepreneurship, which I would argue is a more apt juxtaposition to the "schoo

Basically, pandas, numpy, and matplotlib give me everything I could have wanted out of matlab from a numerical capabilities and graphing perspective. In my opinion, matlab's excellent object inspection and debugging capabilities can be repl

It was my personal site that I recently "scrubbed" off the web. I updated my profile for my business site. Thanks for the reminder.

Well, a new accelerator Acceleprise (acceleprise.vc) just started up to tackle the space. At the very least, it might be worthing reaching out and talking to some of their mentors. Note: I have no affiliation with Acceleprise

wesm, I can't thank you enough for this library. I own and operate a quantitative finance business. Pandas (+ numpy) has been a godsend. Not only do I not have to pay for matlab licenses, but even the less experience programmers on my tea

It's not just having the dry powder -- it's knowing which companies are worth spending it on. You're either "defending your position" or "doubling down on a loss." Great way to lose money fast unless you can find some real signal in the n

Zen? This is madness! In my mind, Matlab's (Octave's) array based programming makes sense. This? This does nothing that I expected it to do! replicate seems to pretty randomly takes a function. Is that an R thing? I think what confuses

I could not agree more. It's an irresponsible statement and should only be qualified by those entrepreneurs talking about how much money they started with. Though, having been to 500Startups and seeing the amount of 20-somethings there, I

I am sort of dumb-founded that this is on the front-page of HackerNews. I know this isn't a constructive comment in any way, but this link is to a basic post that is going over the different between a list, a set, and a map? Really?

This is the second or third time I've seen a service like this created (getexceptional.com and airbrake.io are two that come to mind quickly). I can only hope this trend continues and in an open-architecture style. The ability to basically
