Pixi is just better.

I genuinely disagree. It seems to me like the planet is overpopulated, that there is massively unfavourable bias in terms of who reproduces the most and that, imperfect a proxy for…

This sort of sensationalist title and article are a great part of the reason why models are nerfed by training them to output absurd disclaimers. Nobody should expect that AI can b…

This paper is rubbish. Trading is ultimately a partial information, sequential game with an unknown number of participants whose payoff functions (and utilities) are also unknown. …

I think that the FAA will demand that Amazon runs the test program without hiccups for a while before considering a more realistic test, such as one with the drone outside of the p…

Too much noise - this means nothing. This is exactly the reason why serious investors give fund managers money not just based on performance, but on process.

Nonetheless, it is one extra worry you do not want to have

I have yet to see it being pointed out that none of the encryption in use for these cryptocurrencies will necessarily remain extremely hard to break for long. A good question is: w…

I know of at least 5 firms who would have the means to make a big profit in a rather stealth way and all of the infrastructure needed to minimize execution risk (to the point that …

As someone who lives in Kendall Square and studies at MIT, I would say that, in spite of the amount of brains, Cambridge and the whole Boston area are a terrible place to live, wit…

That code is a recipe for getting hurt. Here are a few points: - Return is not everything. More informative performance metrics are Sharpe ratio (a sort of reward/risk measure) and…
