It's about time someone took this seriously.

Eventually, some of your code will make a call to IO: reading from or writing to disk, responding to a web query, updating a DB, drawing something on the screen, etc, etc. For example, you could put up a web server written entirely in Schem

If AWS posts a loss it'll be because Amazon is reinvesting resources into its growth, not because they're subsidizing each user's costs.

I suspect the other party gave LinkedIn their address book, and they're trying to maximize the odds of a connection.

First, this sidesteps the question. The writeup implies owners will be able to buy out indie.vc, rather than feed them a perpetual stream of dividends. Regardless of how they do this, what is the buy-out amount? It will have to be an intege

I'm curious to know how they plan to compensate for the failure rate of startups. If half of the portfolio fails (a good outcome), the cashout option would need to be 2x the original investment for them to break even. More if failing c

We wrote a static optimizer for spreadsheets - this looks at the entire sheet and reduces computational complexity where it can. Excel's built-in functions are optimized to run fast individually, not to work in concert. (Also, some of

We're hoping that better performance will let users build well-designed spreadsheets - they'll be able to show more steps and use less archaic formulas without having to worry about slowdowns.

The high kyu/dan level programs are worth playing against. The ones under 20 kyu aren't - they don't play the sort of game you can learn from, especially when you're getting started and don't know what things are su

There aren't any useful AIs to have games with at that level - the mistakes they make are totally unlike how real 30 kyu players play. That's why it's not worth playing them. Plus, the folks on KGS are friendly, and there are

For those interested in learning to play, Kiseido Go Server ( https://www.gokgs.com ) has a fantastic community of users - from total beginners to professional players. It also has an intro you can skim, but don't spend too m

The point is that we don't see eggs break at some times and reassemble themselves at others. Whether time is flowing "forwards" or "backwards" is just a label - if you decided to start calling "tomorrow" &

Python is very readable; those users can usually understand it if they try.

Not at all, it's great to see more products helping people get away from VBA. xlwings is well-done and has some features we don't (e.g. Mac interop), and likewise we have some features they don't (e.g. UDF's). (I'm

We produce the correct result rather than duplicating buggy behavior.

The underlying formulas are mathematically equivalent to the ones Excel uses. They may not match Excel precisely when it comes to numerical issues (things like roundoff error may come out differently, for example).

You're right, but people in that situation don't always have the luxury of rewriting the models or moving to a different tool. Hopefully we can help in those cases.

The calculations run locally, so your data is secure since it doesn't go anywhere. The easiest way to check correctness is to compare what Excel returns to what our engine returns. If there's no discrepancy, you can rely on our ca

We just turn off Excel's computations and then run our own.

Most people who do heavy analytics in Excel don't have the option of importing something into a DB and using SQL, either because they aren't familiar with SQL or because they have to send the spreadsheet (and not just the result o

We got the speed increase primarily by dropping to low-level code (numpy, and sometimes C) in functions that cause bottlenecks. Multi-threading helps too. The largest gains are in the scenario you mentioned - big spreadsheets with a lot of

Actually, they're the same thing: both are computed as (number of shares outstanding) * (price per share). The difference is that market cap is used for companies that have IPO'd (and therefore have a broad market for their shares

This is what I would expect from the underlying mathematics. NaN roughly means the output of a function is undefined, and it does not make sense to say functions are equal at some value just because they are both undefined for that value. F

A four-stone handicap is not small: a beginning professional player could give any top Go player (there are several major championships) a run for his money with 4 stones.
