Balisp Revival 7! lightning talks on retrospection @ 500 statups

Hello Lady & Gentlemen Hackers!

I hope you all had a great end-of-2012!

The first round of lighting talks for 2013 will be this Saturday, Jan 19 at 2pm. They will be at the 500 Startups office on the 12th floor of 444 Castro Street in Mountain View. Sorry this is such short notice! (There were some logistical issues.)

The "suggested" topic for lighting talks this month is: "retrospection" (retrospection on a project, an idea, or some code, lessons learned, humorous anecdotes, personal retrospection, etc). As per usual, topic adherence is not enforced ;-)

There will be a long-form presentation on Preserving Historic Software (eg LISP) by Paul McJones.

After his talk, Paul will be giving away several books, manuals, tech reports, etc that are duplicates of his work in conjunction with the Computer History Museum to maintain an archive of historical Lisp materials. He is very graciously giving these materials away to attendees of this meetup with no strings attached. Here is a full list of the materials:

Additional lighting talks will include:

  • starlisp: a Common LISP with support for *Lisp and other useful features. -- brian guarraci
  • djula retrospective -- Nick Allen

Please email me or post a comment if you have a lighting talk I can put on the "schedule". Also: feel free to also bring questions for discussion the group & we will try to squeeze them in at the end.

Hope to see you there!

Take care

    thanks for the very interesting documents Paul!

    I liked in particular these puzzles

    We solved them all (greatly assisted by my friend Richard Smith) except the last one which I cannot understand

    (DE moby (l)
    (IF (NULL (CDR l))
    (CAR l)
    (moby (CDDR (APPEND l [(CAR L)])))))

    I don't understand what the [] syntax is (why is the L capitalised anyway?). To investigate I started up this interpreter for Lisp 1.6 but it doesn't accept nearly any of this syntax.

    (APPEND '(A) '(B)) outputs as expected (A B) but even the function DE does not exist, it doesn't accept [] and assuming [] were another notation for () it tends to crash in an infinite loop

    For an example of the error output by this Lisp 1.6


    TL;DR What does (APPEND l [(CAR L)]) mean?

      we considered that case but decided that the resulting solution was not pretty enough as a function but maybe we missed some element of beauty in her (as these oddly anthropomorphic papers give their functions as in the Latin a feminine gender)

      do you know if there is a better Lisp 1.6 interpreter to play with?

    A very nice way to meet new people and get an idea of their interests and current activities.

    There were just a few talks, but all were fun. I especially liked the talk about the Computer History Museum's Lisp manual and software collection.

We just grab a coffee and speak French. Some people have been coming every week for months... it creates a kind of warmth to the group.
