This is down to convention though. You decide how you interpret your data in C.

What's fascinating is that I recently found some code that I believe was written in NB [1]. It's compiled to threaded code (like B) but knows about chars (like C). It doesn't quite match the story, but I don't know what

Imagine this: watch two years of the life of every human alive today. You'll need more time than the age of the universe (as far as we know).

That's funny. I have met exactly one person who I know is a Taylor Swift fan. That is much less than the number of people who I know have taken psychedelics.

- no struct/record type - call by name instead of call by reference - no bitwise operators - probably a lot more, I'm not too familiar with the language The quote may have been closer to the truth at some point, but certainly not

The author seems to assume that human consciousness needs more than computation. Certainly a valid point of view, but what is the evidence? If you're not even touching upon the question what consciousness actually is , how can you say

Of course this getting into the whole philosophy of AI and consciousness and whatnot. But for practical purposes I would say: yes

It sure is an interesting time for linguistics now. For the first time there now is a second entity that can understand and produce language. Will be exciting to see how the field will transform.

The paper is the original paper on LISP by McCarthy "Recursive Functions of Symbolic Expressions and Their Computation by Machine, Part I". It has the original definition of LISP in LISP.

A bit strange to talk about 1974 but look at code from v7 (1979).

βαίνω and Bein are completely unrelated. "kommen" (and english "come") are related to βαίνω.

That's really interesting. Was the emulator called SKY by any chance? And do you know if it survived in any way? As a PS2 fan I'd so much love to see it.

Ah too bad. The file chooser after GTK2 became absolutely unusable.

Square roots of negative numbers came up when solving cubic equations, even if the final solutions were all real. This meant the square root of a negative number was not something nonsensical the way you might claim for x^2 = -1, but actual

You can find the Windows XP source code publicly on github right now. So I'm not sure how serious MS actually is about this...

I actually didn't know about n.out before. It wasn't mentioned in the v1 manual so they must have gotten rid of it by then. However it seems that it is just a symbol table that's generated by the assembler. B code is eventual

The interpreter is part of the binary yes. I have reversed what was available here: http://squoze.net/B/ and written my own B compiler that generates the same threaded code as well: https://github.com/a

v4 was the first kernel written in C, and the assembly kernel before that already ran on a PDP-11. I doubt anyone even considered using B for this.

> pasta sauce made with fresh tomatoes taste like tomatoes That probably only works if you live in a country blessed with actual tomatoes. In Germany e.g. it's not easy to find tomatoes that taste like tomatoes.

I wonder if this is a MIPSism? I've seen I$ and D$ a lot in PS2 docs.

Oh I bet fun also played a role. But I don't even know what exactly you are comparing against the PDP-11 here or and what point, because UNIX development happened on 11s for at least a decade. UNIX first ran on a PDP-11 in 1971 or so a
