    A pair of smart modems should certainly be able to connect, but it's very likely they would only be able to negotiate a fairly low speed. The classic 300 baud Bell 103 modulation c…

    As far as I know calling free is optional with Fil-C. It can prevent situations where some memory is no longer needed but isn't freed due to some remaining pointer to it sitting ar…

    Typically, for development, one will start a clean image in the morning and load it up with a combination of newly compiled code and automatically cached previously compiled code. …

    That sounds about right. (Just to clarify, what I was referring to with "did not exist at the time" was specifically Self's JIT and its new techniques.)

    With regards to performance, Craig Chambers's thesis on the Just-In-Time compiler for Self proves pretty definitively that a language as (or more) flexible as Smalltalk can be very…

    That sounds about right. It's very easy to make something resembling a Lisp, and even easier to call the result a Lisp.

    DOOM was definitely made with DOS in mind, but it also ran on NeXT from the beginning. It's pretty portable actually. Since you cited Fabien Sanglard, I guess I should mention that…

    The Build engine's source code isn't enough to port any game running on it, since Build was made as a library (I believe most developers using Build in the 90s didn't have access t…

    Dan Weinreb (one of the founders of Symbolics) wrote a rebuttal to this article in 2007. The comments are also worth reading. https://web.archive.org/web/20121107150708/http://danw…

    It's wonderful when I have to show my ID before I can watch a video of the funny man saying fuck (I'm not kidding, that's sometimes but usually not enough to get it automatically a…

    Why not? That's how proper English text is written. Of course there are many programs that can't handle it properly (or handles it inconveniently) so in practice it might be proble…

    Using the Symbolics Document Examiner was the best manual reading experience I've ever had

    The only notable thing they share is that they were both written in Lisp.

    HexstreamSoft is one guy who decided to piss off just about everyone he could in the Lisp community, then his Twitter account got locked and everyone stopped caring.

    S-expressions aren't inherently more difficult to read than JSON, it's just a matter of getting used to it.

    Even the best Unix shells are a mere toys in comparison to what Lisp machines were doing in the 80s. I don't wanna say that using a Lisp machine was "life changing" or anything but…

    Season 2 started off better but quickly deteriorated (shortly after lots of positive reviews were in), and I completely forgot about Season 3 after I'd heard it existed.

    I don't think anything has ever disappointed me quite like Star Trek Discovery did.

    I agree with your conclusion but I don't think it can just be extrapolated like that.

    There are videos that are age restricted because of swearing. Porn isn't the issue here (especially since it's not allowed on YouTube even with age restrictions).

    Hearing the funny man say fuck now requires ID, wonderful.

    I've only seen this survey on r/lisp, so it's likely that only people involved in that community have answered.
