    @gewt This is because OpenBSD is 100% secure, and this is achieved by running 0% useful application. CC @amszmidt

    @amszmidt @Ardubal As for Common Lisp: we forgot where the name came from but we think we inherited some random characters from 60+ years ago.

    @amszmidt @Ardubal A True Schemer can't even DPB without first writing a "Lambda the Ultimate Bit Inserter" paper about it, and then designing a hardware DPB chip in VLSI.

    @amszmidt There's also the related Design Programming Language, or DPL. Among other things, they were used for the SCMEME-81 chip.

    The scheme-chip.net person and I will make an effort to recover this software.

    @amszmidt Have you seen a VLSI design suite called Daedalus? It's written in Lisp; started on ITS and moved over to the CADR.

    @amszmidt From a brief look, it seems like a faithful replica. Do you agree?

    @inthehands @jwz This sounds like fun, but impractical. If you want the hack value, go for it!

    As for me, I just want to edit text in style. That's the problem I'd like to solve.

    Hot take? Every editable text field should be an Emacs buffer. I don't want your semi-arsed Emacs keybindings, I want the full thing.

    @AmenZwa @brouhaha UNIX is clearly not incompatible enough. I know a timesharing system that is.

    @aka_pugs I believe SUDS drawings for the early Sun hardware can be found on PDP-10 backups. Thoughts?

    IBM may have the best mainframes, but DEC has a month named in its honor.

    @amszmidt @weekend_editor @cstross Why is it hard?

    I found it hard to write a Forth cross compiler. My mental block was mostly that the same symbol may refer to three different things depending on context. In a way, boostrapping a language using itself can be more confusing than doing it from another language.
