> My graduate school experience convinced me that I was not smart enough to be an expert in the theory of algorithms and also that I liked procedural languages better than functional ones. I wonder if that last bit was as unfashionable a statement when he made it as it would be now.

> I liked procedural languages better than functional ones. (Emphasis, mine). I suspect that he understood functional languages quite well. He just didn't like them. I like some aspects of FP, but there are other aspects that I don't like. My own development style is a ghastly chimera of techniques, technologies and jargon that coagulate into a disgusting bouillabaisse that makes everyone go "tsk, tsk," but that alwa…

C is clearly influenced by functional languages.

Though C programming is usually about effects, effects occur in expressions which usually return a value except in cases when their type is "void" (which was a later introduction into C, possibly from C++).

C even has an if/then conditional that yields a value, the ternary operator x ? y : z, which is a more strongly typed version of (if x y z).

> I like some aspects of FP, but there are other aspects that I don't like. Care to enumerate? Asking because I feel the same: I really enjoy immutability, first class functions, map/filter/reduce, Option and powerful types (I dislike: currying, point-free, monads), but at the same time I feel more at home doing that in imperative-ish languages like C#, JS/TS and Rust where I can have guard if s and the odd mutation…

I like first-class functions. I actually like currying. But I also like state, polymorphism and identity.

Are you sure you don't mean partial application?

Umm, doesn't Excel use Visual Basic (VBA) under the hood?

No, AFAIK, VBA is just a scripting layer exposed by Excel, not what Excel uses itself.

What do you mean by "using itself"? When you write a function in an Excel cell, IIANM it's a VBA function. Excel is implemented in C++ IIRC.

Out of curiosity: what 'ancient' technical reports are you looking for (plus who knows someone here might know something)?

The only ancient technical report that I am looking for currently is Mark Morkovin's 1960 AGARD conference paper titled "The structure of supersonic turbulent boundary layers". This was presented at the April 1960 Boundary Layer Research Meeting of the NATO AGARD Wind Tunnel and Model Testing Panel in London. I have tried contacting many different people about this without any success. Morkovin died in 2015 around th…

Maybe check with https://twitter.com/ColdWarScience, she's a historian and editor, specializing in the Cold War era of course

Fascinating and sad. I'd like to tell a similar story with a happier ending. I was looking for the first volume of JH Schroeter's observations of Mercury (published in 1788!) when I was writing my own PhD, and found it thanks to contacting a group of fans who were working on restoring and collecting his heritage in the Lilienthal observatory. All of my previous efforts had failed, but I learned my lesson here: if you want something hard to get, look for people who might be obsessed with the subject.

I am not surprised about the effort it took to find a copy of Ritchie's dissertation. Dissertations tend to be difficult to find if they are not already listed on WorldCat or in ProQuest. But the museum used the best method in this case: talk to people close to people who had a copy at one point. In my experience when all else fails, this strategy is the primary one that ends up working. It doesn't work all the time,…

Some people like myself and gwern have lists of papers that we're looking for:

Random Dennis Ritchie story: my high school principal was Dennis' brother, John, and had a "UNIX Magic" poster ( https://i.imgur.com/aqg21UI.jpg ) hanging in his office. I asked him what that was about and he dismissed it with a wave of his hand, as if annoyed: "oh, just something my brother did".

Someone posted a high res scan of this on reddit if anyone else is interested: https://www.reddit.com/r/unixporn/comments/91ntoh/comment/e3... Unfortunately no scan of the other two (feuds and views). Here someone find a more permanent place for it: https://send.firefox.com/download/c1783a94da0e8cfa/#sklTlfgc...

It says it's in the owner's trash now for some reason!? I want this so bad.
