“Mediocre success”, as described by the author, is how great science starts out. You try an experiment, (eventually) get a slight indication that your hypothesis might be valid, and then keep iterating until it seems clear that the idea is

For a good introduction to developing an intuition about special relativity via low speed of light, I really recommend George Gamow’s “Mr Tompkins in Wonderland” (or “in paperback”). These short stories explore things like how the world wo

This is great work. I remember seeing them on my keitai mid 90s but feeling that they were familiar. So filling in some gaps like this helps me not feel like I was crazy.

As far as Lisps go, Teitelman implemented DWIM just for Interlisp (annoyingly it was the macro expansion engine so you couldn’t disable it). MACLISP and its derivatives never had that misfeature. Of course the general concept was taken up

What’s with the “late stage” part? People have lived rough (under bridges, squatting, and wherever) through all stages of capitalism, including before capitalism.

That was back in the early 60s, funded by ARPA as part of Project MAC. The “customers” were the kinds of people who cared about the rainbow books (hint: all government), though the science was open. ARPA (later DARPA) funded a lot of thing

Sure, but some people suffer some small depression and recover and others more profound depression and need more extensive treatment. I think we can all recognize that these two situations are different. So if there’s a pet ban for whateve

I can't really evaluate your comment on relevance -- some things do seem to inexplicably bog down, but on others they move usefully and quickly. And the conservatism of compatibility really is incredibly important, which I say as some

MACLISP was most definitely a compiled language, it’s just that like modern Lisps you could mix the two (compiled and interpreted code). I tried to be clear by using the modern terminology “generic function”. If you compile a function with

I hate most simplistic metaphors but this one is insightful. This is a big reason why Microsoft blew the mobile phone biz: their customers were not the users; the customers are central IT. The iPhone was such a revolution at the time that

Early workstations (Alto, CADR, PERQ etc) were portrait, and a lot of development was done on portrait ASCII terminals too (e.g. AAA). I was always puzzled as to what caused the switch in the mid 80s.

I don't know why this is downvoted; perhaps it was not clear that I am talking about the US federal government specifically, through the National Vaccine Injury Compensation Program, set up by a 1986 law. Without it companies were g

Thanks, didn’t know the floors were also structural supports. I thought they just hung from the central core. Oh well.
