Artyom BologovLamber, my <a href="https://merveilles.town/tags/LambdaCalculus" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LambdaCalculus</a> -> Lisp compiler (<a href="https://github.com/aartaka/lamber" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/aartaka/lamber</a>) didn't handle big enough numbers (> 10-bit,) so I decided to implement some optimizations, reusing underlying <a href="https://merveilles.town/tags/CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a> compiler to speed up and save space on numerics. It's not particularly reliable, because big LC numbers consume too much of the stack, but at least it's better than it used to be, almost reliably handling 12-bit numbers.

screwlisp<a href="https://mastodon.social/@rzeta0" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@rzeta0</a> since you have gone through introductions to quite a few different languages, including recently <a href="https://mastodon.sdf.org/tags/commonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#commonLisp</a>, I wonder if you might provide some comments and questions live in next week's <a href="https://mastodon.sdf.org/tags/lispyGopherClimate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lispyGopherClimate</a> where we'll have <a href="https://fe.disroot.org/users/ramin_hal9001" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@ramin_hal9001</a>, and treat the many different facets of the <a href="https://mastodon.sdf.org/tags/lisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lisp</a> family (now and through history). I just think you might have something interesting to say.

Paolo AmorosoWeb developer KILLIAN.arts posted a review of Common Lisp: A Gentle Introduction to Symbolic Computation by David Touretzky. They read the book because:"While I like web development, I have worried about specializing too much as a frameworker or a UI builder, missing out on more fundamental knowledge of computers and programming."<a href="https://killianarts.online/en/articles/common-lisp-a-gentle-introduction-to-symbolic-computation" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://killianarts.online/en/articles/common-lisp-a-gentle-introduction-to-symbolic-computation</a><a href="https://fosstodon.org/tags/CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a> <a href="https://fosstodon.org/tags/lisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lisp</a> <a href="https://fosstodon.org/tags/books" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#books</a>

Karsten JohanssonAnswer: It's a cyclic number, to a point. But if you multiply it by 7, the answer is 999,999. There is both a mathematical connection (It starts with the repeating decimal in 1/7) and a connection to the Gurdjieff Work (used in formulating the Enneagram).I thought it was interesting how it cycles, then 999,999 all of a sudden.<a href="https://infosec.exchange/tags/lisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lisp</a> <a href="https://infosec.exchange/tags/commonlisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#commonlisp</a> <a href="https://infosec.exchange/deck/@ksaj/114233197996824014" translate="no" rel="nofollow noopener noreferrer" target="_blank">https://infosec.exchange/deck/@ksaj/114233197996824014</a><a href="https://infosec.exchange/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#python</a> <a href="https://infosec.exchange/deck/@ksaj/114233177193135419" translate="no" rel="nofollow noopener noreferrer" target="_blank">https://infosec.exchange/deck/@ksaj/114233177193135419</a>Wikipedia <a href="https://en.wikipedia.org/wiki/142857" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://en.wikipedia.org/wiki/142857</a>

The Medley Interlisp ProjectSpinPro™ was an expert system to design procedures for Beckman Instruments ultracentrifugation machines at biochemistry labs. Developed in Interlisp-D on Xerox 1108 workstations, SpinPro™ was deployed to IBM PC/XT computers as an application that ran under Golden Common Lisp by Gold Hill.To learn more about SpinPro™ see this 1985 paper:<a href="http://www.bitsavers.org/pdf/xerox/interlisp-d/newsletters/Masterscope_1-03_Aug85.pdf#page=2" rel="nofollow noopener noreferrer" translate="no" target="_blank">http://www.bitsavers.org/pdf/xerox/interlisp-d/newsletters/Masterscope_1-03_Aug85.pdf#page=2</a><a href="https://fosstodon.org/tags/ExpertSystem" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ExpertSystem</a> <a href="https://fosstodon.org/tags/interlisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#interlisp</a> <a href="https://fosstodon.org/tags/CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a> <a href="https://fosstodon.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#retrocomputing</a>

Karsten JohanssonLisp Fun. A mathematical oddity.Some numbers, when multiplied by consecutive numbers, produce a bit of a cycle. Try this code and notice that all the answers are permutations of the same number, 142857.(defun cycle-142857 () "Prints the magical 142857 × 1..6 cycle." (let ((n 142857)) (format t "~%Watch this cycle:~%") (loop for i from 1 to 6 do (format t "~d × ~d = ~d~%" n i (* n i)))))When you've exhausted your fun running it, increment the number to see what 142857 * 7 gives you.<a href="https://infosec.exchange/tags/commonlisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#commonlisp</a> <a href="https://infosec.exchange/tags/lisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lisp</a> <a href="https://infosec.exchange/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a>

Mistress RemiliaBenben's audio engine (playback, FLAC reader/decoder, effect stack, resampling) is now all working in pure <a href="https://xn--nanako--c83f6n.mooo.com/tags/CommonLisp" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a>, no bindings (well, except libao for the final output). Also working are a few other bits that I've ported over, like the configuration settings and metadata handling. Just FLAC files at the moment, but the others will follow very soon. I haven't ported the UI yet, so it's just running in Emacs/Slime here with a very simple macro to init/deinit the audio output. Performance is within just a few CPU percent of my existing Crystal version, and that should tighten up further. <a href="https://xn--nanako--c83f6n.mooo.com/tags/LinuxAudio" rel="nofollow noopener noreferrer" target="_blank">#LinuxAudio</a>

It includes a library for meta programming, sophisticated interactive error handling, an interactive object system (CLOS) and a lot of other stuff integrated into the language.

Jonathan LamotheSo, I've been taking another run at learning <a href="https://social.jlamothe.net/search?tag=CommonLisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CommonLisp</a>. The last time I tried, I simply could not wrap my brain around macros. I'm reading the same book again, but this time am a more experienced programmer, and it all just clicked in my head.I might actually end up enjoying <a href="https://social.jlamothe.net/search?tag=Lisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Lisp</a> after all. I don't know if it'll dethrone <a href="https://social.jlamothe.net/search?tag=Haskell" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Haskell</a>, but I'm starting to get why people like it.
