"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 optimiza…

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 l…

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_L…

"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 …

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 …

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 rea…

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…

It never really says it is an acqui-anything. Maybe they are just winding down and getting jobs?

Robert Martin ( https://en.wikipedia.org/wiki/Robert_Cecil_Martin ) once tweeted (@unclebobmartin): "When designs are cheaper than builds, e.g. a skyscraper or a bridge, big up fro…

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 …

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 yourse…

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 …

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…

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, wh…

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 excell…

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.…

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 li…

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 los…

I met Dave when I was interviewed as part of his "Shadow Dave McClure" contest last summer ( http://www.internmatch.com/dave-mcclure-job-shadow ). Getting to sit down and talk to h…

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 take…
