The majority -- perhaps the vast majority -- of headge funds are long/short funds. In the canonical example, if they think that Pepsi will perform well because of some new health products, then they will go long Pepsi and short Coke. T

Arbitrage opp: Write a program to take the opposite side of any bet that you can hedge in the public market. For example: if someone bets against Tesla, and you can take the opposite side, but (more) cheaply offset your risk in the option m

I agree with your description of he dynamic at play. It raises two questions: 1. Is the money that the startup attracts responsible for its success? In other words if a mediocre company goes through Y Combinator and then attracts a $55 mill

The part of this logical chain that I don’t follow is the low cost of living attracting companies. I can see why low cost of living ought to attract companies but in practice the new companies seem to gravitate towards already high cost of

The article has uncovered sources that claim the algorithm makes the ultimate decision and other sources that claim it doesn’t. If it does make the ultimate decision and not just for political reasons then this is very interesting. Having

Great question. In theory, jobs put an upper limit on housing usage. People almost always follow jobs. There are many beautiful cities in the world but only SF is near Silicon Valley. You can find cheap housing in nice areas if they don’t d

You misunderstand the sense of "true" here. The point is not that the "true" price in the sense of what it ought to be. It is the "true" price in the sense of what the market is actually paying for the service.

Yes, and any estimate of solar only costs is composed largely of financing charges which is another way of saying capital costs. These include the installation.

That is true, and existing infrastructure does (mostly) handle the gaps. How much does "existing infrastructure" charge to handle the gaps? This calculation differs wildly from as low as $6 to as high as $15, but I think $12 is th

The true price of solar is the price to produce reliable, continuous energy. That requires something to smooth out the signal and store the energy, most probably a battery. The solar + battery price is also going down, though not as fast as

This is great. I wish we could do our own arbitrary style analysis on the data set sort of the way one can do a factor analysis on a portfolio. I would look at words that are common between Marukami and McCarthy compared to the rest of the

Not sure why you're getting down-voted. You're right, the author didn't close the loop. Typically we would expect to see an insight after you apply the ML technique. So they extracted features, clustered the pages and found..

This looks interesting. Is it basically a hosting site you can pay for with crypto? This makes other things possible: anyone can pay for it using crypto etc? I can imagine some use cases, but since you've been thinking about this a lot

I concede the point: the "best" explanation is best in a context. The best explanation for a PhD candidate about to defend their thesis the next day is not the same as it is for, say, me. But that reinforces the point I am making.

This was a pre-internet book though. The internet has made explanations hyper competitive. At this point I can find dozens -- perhaps hundreds -- of explanations of Godel's theorem. But in the pre-internet days I could go to the librar

Actually, with Tensorflow as a Keras backend, I would expect them to be the same. I am not sure where the performance difference between TF and TF as a backend come from. I do think that pure TF would be easier to scale up over multiple ser

I appreciate how you focus on just two, which are the state of the art in your opinion. I find it less useful to see comparisons of "top 50 deep learning frameworks for 2018" which include esoteric stuff that is only there for sak

As others are pointing out, TF isn't that hard. Or, rather, it is hard but the difficulty is from getting an intuition for what part of this weird multi layer net is producing this weird behavior and is it an artefact or something in

Great Viz. Although my favorite is still the video of Andrej Karpathy's Stanford lecture explaining it. He sort of goes through some other implications which, from an intuition massaging pov, is great. https://www.youtube.co

I half agree with you. The notation alone, although "understandable" doesn't provide a "deep" understanding. I think the intuition is only half-transmitted with just the notation. I do think working through an examp

There are probably others who get frustrated, but I don't think most people do. I think its fine, and I haven't heard others complain about it over the years.

One of the interesting aspects of Foucault's take on power was that it was constitutive. To put it another way, the company that reclassifies what it does, or uses a new taxonomy may actually be trying to change itself by doing so and

It is certainly an interesting problem. I don't know that I have the solution. I agree with everything you said about the problem around finding a good reward. However, coffee drinkers can be picky. It would not motivate me, but then a
