The Fidelity "minus sign mistake" didn't create a loss. The mistake was in relaying the information to the end user. It didn't actually cause a loss of that magnitude. That is like…

I am not offended that you think I may not program. That is fine. (I mean less than some, more than others. I have coded up the examples I brought up.) But you haven't responded to…

True, if we were talking about Data science, and you were bringing up Python or R or Julia, fair enough. But if you're talking about Racket, I would want to know what you can do wi…

Well, I assume people write mountains of code in the library. If you're making a machine learning product, that is still a lot of work. However, writing your own Tensorflow interfa…

I am always confused when people talk about the language itself. In my experience, python is used for Tensorflow, or Pandas, or Django, or Flask, or pytorch or something else that …

Agree 100%, but only if it is a one time activity. If you have to automatically pull files and do the operation several times, it is better to go with R (or python, or awk sed or w…

I was waiting for the critique... but I never quite saw it. Imho, the data problem Tidyverse is trying to solve is basically the ones we face in a database. So, select, join, inner…

Don't you think it was policy so they can capture the information and get reporting?

I've been trying to explain to people why I think ML is Stats rebranded but this is the most succinct expression of that sentiment: > Taking averages, grouped by something? That's …

I don't think it would be questions. Suppose you like fountain pens, and you recommend certain ones. One of your friend looks for fountain pens that their friends recommend and fin…

It was thought that one way of finding information is to ask your network (Facebook and Twitter would be examples), and then they would pass on the message and a chain of trusted s…

It went down a few times before and I reached out asking if he wanted help too. He did respond fairly promptly ( Are the articles the same as he had? Did you get a snapshot before …

I admit, it really makes you think about iterations and MVP in a new way. I am surprised you said you found flask lacking though, because I would have thought they were similar. Ca…

This is really interesting. I would love to see something like this for other successful companies. Too often, we see the tech stacks of famous firms, but not the stacks that prece…

These declarations of valuation should be followed by a little note explaining what multiple of earnings (or, failing that, sales) this represents, and how fast it is growing. Is t…

You guys think this is bad? In finance, I've seen people compute deals worth billions of dollars using excel spreadsheets and a team of MBAs.

There are so many little details to remember when you implement a Neural Network from "scratch". Or, I suppose, even if you do not. You know what would be a great contribution? An …

I think there is an error in the title. It should read: "Starting a Company Outside Silicon Valley Saved Me Just $1.1M"

Accepting the null hypothesis has utility only if you have some reason to believe it would not be accepted. Accepting it per se has no particular value. You could generate several …

Alternative take: there isn't that much low hanging fruit there. Hear me out. "To the person who only has a hammer, everything looks like a nail." The data in front of your is the …

Insider trading is wrong based on the theory that the insider -- the owner of some shares -- has a fiduciary duty to the company. That's why there are no equivalents in commodities…

Well, if you accept the premise that this is "fine and good", then why should[edit:n't, as in why shouldn't] the PE class beat the S&P. Let me tell you a story that may or may not …

It would be more interesting to see if the top Private Equity firms are consistently the top firms. note: if private equity matches the market, the top firms beat it. I am not surp…

This doesn't take away from the exercise, but I notice the model seems to "predict" the movement just after it occurs. It just lags the current price. If there is no alpha in the p…

Alternative explanation for modern writers: write then there is less breaking news. “Important” news feels important and one may feel more justified in attending to it.
