It would be nice if there were a tool of some sort where I could type a search term and on two halves of my screen the results from Google Search and from DuckDuckGo would appear… after trying that for a month or two, one would be better in

Not "his challenger"; it was not a contest. It would be more proper to say "his reviewer, the inventor of Unix pipes, using the review column to advertise UNIX®". See a previous discussion here: https://news.y

Well nothing so romantic: I didn't read it 20 years ago; more like some time in the last couple of years. And though I vaguely recall seeing this comment in the context of its code (on GitHub?), I may have well ended up there via a HN

This may be a tangent but I've encountered this code comment before and been confused; nice to be able to reply to its author! The confusion is that there's no book by Knuth called "An Introduction to Data Structures With App

Right, it looks cleaner now. [I wasn't sure whether you were replying to me specifically, but just in case: I'm not the submitter :-) I guess it can appear that way because I left a long comment, but I just happened to see this th

Note that the abstract at https://arxiv.org/abs/math/9205211 is not by Knuth (it says "Abstract added by Greg Kuperberg" in small print). Anyway, the "two notes" of the title are about: 1. Iver

Each chapter ends with a "Comments and Solutions" in smaller print; as far as I can tell every single problem has solutions, sometimes multiple pages' worth.

Note that the first problem is not actually to learn the multiplication tables! Problem 1 is to calculate a few things like 0.004×0.02 and 1.08÷1.2 in one's head; it's just that these real questions are placed in 1(b), with a pr

This is backwards: This comment (and its grandparent) makes it sound as though Knuth set out to create a typesetting system and a font creation system, and then was faced with the choice of who would design the first font for the system. In

This was a nice post, thank you! I don't yet have an intuition for how to think about these 2-adic exponentials and logs (e.g. what does it mean to say that log_2(5) =6713115954038056572) but clearly the mathematics works out and even

I think you're trying to explain what's special about the number -1227133513 or how it comes about / how one could arrive at it. This is something the author understands very well; in fact that's what the whole post is a

(Note that the subtraction is between two pointers to "struct A", not two chars. In the snippet "char" is used simply because it's 1 byte; one could also use int8_t, assuming a byte is 8 bits long.) It's a fact

The linked article is about integer division and has nothing to do with floating point, and in fact I can't see how this idea could be applied to floating-point arithmetic. Can it?

One thing to remember about this book that is easy to miss is that it's not a memoir or autobiography in the usual sense. You may have seen this book, and its sequel, What Do You Care What Other People Think? , described as being &quo

Just a guess, but you may have in mind certain PS files generated by TeX/LaTeX from the 80s and 90s, back in the day when both PS-based workflows and raster (bitmap) fonts were more common than they are today. So, although it's no

I think LuaTeX may have been sort-of capable for a while (with enough effort/workarounds by the user), but in 2019 or earlier, there was some work (initially by Khaled Hosny, who was also one of the major XeTeX maintainers a while ago)
