I'm glad you found my blog post hilarious! But let me tell you, I don't need to ramble or switch subjects to make my point. I am the best at getting straight to the point, and nobody does it better than me. Believe me. I have the best words and ideas, and my supporters know that. I am a winner, and my blog post is a winner too. Sad!

Re: Lispology - Finding repetitions in a list

alandipert — Fri, 23 Aug 2019 11:49:42 -0000

Another great post, thank you. It occurred to me that a max heap
might be the ideal data structure to maintain as you traverse the list.

An optimization idea for very large inputs that came to mind: If the length
of the input is known (and is expected to be very long, but the set of
items small), the heap could periodically be pruned of entries that
couldn't possibly occur the most, given the size of the list that
remains.

I'll throw in a couple:


(loop for i in '(1 2 3 4 5 6 7 8 9) sum i)


(do ((nums '(1 2 3 4 5 6 7 8 9) (cdr nums))
     (sum 0 (+ sum (car nums))))
    ((not nums) sum))

Fun challenge! Here's mine:


(defun mysort (xs)
  (loop while xs
        for x = (reduce #'min xs)
        do (setq xs (remove x xs :count 1))
        collect x))

Thanks for the explanation - I updated the post.

I don't have a Mac around to test on, but you should be able to run the JVM in client mode by adding the -client flag to your java command.

No problemo. I updated the Clojure link and example to use the current version of match (core.match); you may wish to update your gist.

Thanks Julio, I'm looking forward to talking about them!

Re: The S-expression Editor

Freakin' sweet. Recently I ran into Nokolisp, a Lisp implementation with its own built-in structural editor: http://www.youtube.com/watc...

If and when you find that Interlisp, let us know! Thanks for stopping by.

Hi Taylor, thanks for dropping by. The server it used to be on went away, and the machine I had it on broke, and I can't find it in any of my backups :(

It worked by loading SHJS similar to the way it's done here: http://www.ejeliot.com/blog...

Thanks, that's really good to know.

Re: Polyglot Folding (Ruby, Clojure, Scala)

alandipert — Thu, 31 Dec 2009 15:30:14 -0000

Awesome! Seems faster too:

➔ time ruby -e '1000000.times { [1,2,3].inject([]){ | xs, y | xs << (xs.last || 0) + y }}'
5.87s user 0.04s system 99% cpu 5.935 total
➔ time ruby -e '1000000.times { [1,2,3].inject([0]){|xs,y| xs.unshift(xs.first + y) }.reverse.slice(1..-1)}'
7.35s user 0.04s system 99% cpu 7.430 total

Perhaps Array.first and .last have the same complexity and the difference is then the redundant slice and reverse calls?

Thanks! I will.

Re: alan dipert - The Silent Helicopter

I think it's possible. I have a friend who says he saw one land near his camp in the Mojave on a dirtbiking trip. Him telling me the story is what prompted me to post this.

If they exist, they're probably part of a top, top secret government research project. As far as I know, they don't have a name.

Anyways, thanks for stopping by!

Re: My EngineYard Contest Odyssey

Actually, those were the only words I used. EngineYard provided an RTF file of 1000 words when they began the contest. I just converted this list to plaintext, renamed it to words.txt, and put it in the repo.
