Well, sure, and so you rarely or never go there. Most people I know don't have a car. Doesn't mean there aren't cars in the country.

> paste can be used more than once Not in Excel after you cut. Because there, cut & paste is seen as an atomic move, akin to what's described in the article.

Well, it's useful. When the iPhone initially didn't support it, people were unhappy, and it was added soon enough.

Have to disagree here. I think Excel is amazingly well engineered, and very well designed for the majority of the users, despite some flaws. Excel is a bit complicated for cut/copy/paste, because you have not only the content of t

> you could have a separate short cut that grays out the text and then moves it to where you want. That's basically drag & drop (on macOS).

BTW, counterexamples in mathematics are really important and often help to refine definitions and sharpen proofs. 1) I recommend the wonderful 1976 book Proofs and Refutations by Imre Lakatos. 2) There is a considerable list of books dedi

BTW, there was a variant of this discussion with the iPod and mp3 players back then. Some people wanted to manage music "by hand" in the file system, and had various schemes for doing so (folders for genre, then artists, then albu

Indeed. Particularly when traveling, I often look for just several bytes of information (an address, when the ferry leaves, etc.), yet the websites contain several megabytes. Frustrating & slow.

Yes, the bash.org IRC archive archive is hilarious: https://web.archive.org/web/20230620135556/http://bash.org/?...

My intuitive take: Eigenvectors answer the question, if you have a linear mapping from a space to itself: which lines through (through the origin) remain unchanged after the mapping? And the associated eigenvalues tell you how much a specif

Just to add: Credit is also due to Prof Christian Reinsch from Technical University of Munich (in addition to Golub and Kahan) for the invention of the practical algorithm for computing the SVD still in use today. https://blogs.m

BTW, if you wonder about the dedication ("For Gene Golub on his 15th birthday"): Gene Golub was a numerical analyst, and father of the practical singular value decomposition (his license plate read "Prof SVD"), together

Indeed. I like to say, we would like three things to be true: 1) Every day has 86400 seconds. 2) Every day is from noon (sun exactly above) to noon (sun exactly above). 3) We use SI seconds. You can't have all three. Pick any two: 1, 2

As my Linear Algebra prof used to say, basically everything is applied Linear Algebra.

Not really. It's still the standard deviation, and it still gives you bounds on probability, for example the Chebyshev inequality: P(|X-\mu| > k \sigma) < 1/k^2. So, while for a normal RV, 5% of observations lie outside +&#x

That's disappointing, both that the vulnerability exists in the first place, and that Apple takes over a year to not even fix it.

Even with equities, things are not entirely trivial. A few examples: Some stocks trade in one currency, but pay dividends in a different currency. Some stocks go ex-div before the dividend amount has been determined (e.g. in Japan). Stocks

Well, that's not money created out of nowhere. The balance sheet extension creates money and an equivalent liability. That's the point of the statement, not money supply and its regulation.

But it's a good idea to keep those values distinct from actual money. You can't pay a fraction of a cent to anyone.

What are those pretty trivial ways? And how are they better than storing 10 cents + 20 cents = 30 cents?
