I'm trying to get myself to finally switch to Firefox thanks to this post. But I'm having problems with ctrl +/- changing of font sizes. In Chrome, that setting affects one domain only. Here I'm getting confused because

The left and right limits are required to exist (and finite), but not necessarily to be equal to each other. So f(x) = 1/x and sin(1/x) are out but x/abs(x) is not.

The key I think your article is missing though is that it should explain which numbers are representable exactly as floating points. This is very important information for other reasons too and that tells you how close "as close as p

I disagree and think that the article manages to fall into an "uncanny valley" of not-actually-understanding. Why else would it need the "A Cautionary Tale" section at the end? That's the first time he mentions that

I think this is a poor take on floating point numbers. Read the classic article it references instead [1]. The IEEE guarantee is not that the result is accurate to a relative epsilon but instead is the closest representable number to the

They're correct that the "In mathematical terms" version of it is wrong (even for addition, if one is negative). It's missing fl()'s around the other a's and b's. Your statement is greatly superior than th

I would generally want the intervals to cover the entire domain (or rather for their closures to cover it). And half-infinite (or all of R) intervals would also be allowed, but I couldn't think of a good way to state that concisely. An

No you've missed the distinction. In all cases the domain and range are R (you can fill in a value at 0, it doesn't matter which). See the MathWorld page which leaves the definition intentionally ambiguous: "A function or cur

I think you missed the point of the example, which is that people rarely clarify this because to the author their definition seems obviously correct. I made it 90% through a PhD without having considered that there could be more than one po

The simplest gotcha I know is: is f(x) = 1/x piece-wise continuous?. This is calculus 1 level material and yet author's disagree significantly on this point, sometimes without specifying it! Some say yes, others would require f t

I think this actually makes it more understandable. If recirc is a special mode you have to activate in your car's AC, then it's reasonable to assume it's not the default mode for your house AC too. Since they never had a &#x

One problem is that no one seems to know that AC systems recirculate air. I literally can't get people to believe me when I tell them this. When buying a window unit recently, some models had the ability to incorporate fresh outside ai

How much does the preamble to the prompt matter? When you remove the word "nonsense" from the prompt, does it do worse at identifying when questions require a "yo be real" response?

I think you're overstating the complexities of pinyin, even if Zhuyin is better. The context pinyin requires is extremely limited, being exactly only the rest of the syllable. It's simple if one just thinks of it as a set of initi

Exactly. And a book shouldn't be listed as a "banned book" because one overly-cautious librarian decided they shouldn't have it in a school. You wouldn't call something "illegal" if it were illegal just in

I do this guessing while trying to read an unknown charger but this article made me question the usefulness of that and is exactly why I'm unsure what the process in Chinese should be. Doing this looks more like the cueing process of p

The article claims that bad readers memorize a handful of high frequency words and rely on those. I read the parts you quote as saying that those words are not memorized as a chunk and I don't see how a similar process can be done on C

I'm learning Chinese and I think you've avoided the question. The crux of the matter is how to learn the thousands of character-to-pinyin/meanings mappings. It doesn't fit at all into the phonics description given in thi

I do dislike the phrase "banned book" because it doesn't indicate who banned it, which is all that matters. In this case, the Nazis over the author's political affiliation (to save you from the click bait title).

Yeah, exactly. The first or second example in any explanation should be buying a banana that you immediately eat. That way the reader sees that an "account" doesn't have to be a bank account nor even a collection of physical

The stumbling block for me learning it was understanding how to record the simplest and most common transactions like buying a banana. Surprisingly many explanations only use examples like paying your home mortgage where the credit and debi

Thanks Wes, pandas and Arrow are great projects. Is Feather now ready for long-term storage with the V2 release? And now that it's just a renaming of the Arrow IPC format, what's its future?

This is just a mismatch with how HN posts pages and how projects expect their release pages to be read. Release pages are for users to know what changed. But HN likes to link to original sources and not articles about the source. In cases

I think HN is awfully addictive, though slightly less so than certain other sites due to a slightly bounded amount of content. Though I think it has helped my life in some ways, it's probably a net negative. My real problem is what sho

Don't you believe it has largely the same negatives as other social media like Twitter or Facebook? (At least in terms of the present topic that "news is addictive".) Why drop one but not the other?

It's "anchored" by $50 million (of which half is support). But what does "anchored" mean here? The article also lists an additional $20 million from UF. I wouldn't be surprised if there was even more.
