Re: New blog - "PicoLisp for beginners"
Hi Mia, Thanks for posting here and starting this blog. There are a total of three blogs at the moment. Last one I feel could be further simplified, it's great effort by you. The flow and flair make it all the more interesting to read posts in one go! I loved the first article. Thanks again. Also I'm glad you liked the mind maps! :-) Hoping to read further and also contributing by way of more mind maps.

Re: Picolisp Outlook
Hi Tom, It appears that so long as the virtual machine abstraction is of any value the PicoLisp ecosystem will continue to grow. PicoLisp basically is Cell (cons pair) processing. One needs to approach PicoLisp bottom up from cell. Surprisingly the cloud and its serverless abstraction are ultimately abstractions of a virtual machine of a different scale and type, that is orthogonal to PicoLisp. There is already a docker implementation of PicoLisp on SmartOS of Titan cloud. Please search and discover. PicoLisp ecosystem appears to be super safe as it is based on future-proof virtual machine architecture, hence as safe and future-proof as mathematics

Re: PilCon Schedule
Dear Mr Alexander, Maintaining a schedule page on wiki will be a good idea. PicoLisp is simplest (small) by definition and motivation, so least number of participants should not matter. Merit is not decided by number of people. In the iconic "The Unix Programming Environment" book by Kernighan & Pike, small number of developers (two) is mentioned at end of classic book, while examining the reasons for successful design of Unix. Thus, number of people do not matter, the sessions are extremely fruitful and we all gain a lot of insights. For me in particular asking my queries have been the best way to go forward. As far as I know it is possible to record in Jitsi application by the admin of the conference. https://jitsi.org/user-faq/#:~:text=The%20easiest%20way%20to%20record,and%20access%20the%20recording%20there
Re: Tomorrow is PilCon
Dear List and Pilcon Participants, I'm adding here the points that I feel will complete the recap given earlier by Olaf. Kindly take notice and correct me incase of any error. 1. Database not required for learners. Lists and symbols are sufficient. As per Alex, symbols are higher level concept than lists in picolisp. 2. Common lisp is more list centric. When Alex was starting out in 1980's he was advised to understand and work around symbol more than lisp. At the machine level, symbol is also a cons pair. But apparently it's not needed to be understood while programming. 3. Example of shopping list. Apples, bananas really useful. This was done first by setq making cons pairs in definition. And also later defining a class and object. 4. Great question by another participant (I'm sorry, not knowing name) to ask why take numbers in car of cons pair (in example given in point 3). car in cons pair is good for processing. Lot of functions and function processing can take place. Geo, my Org Babel works perfectly with Picolisp, I'll still review link shared by you. Thanks to Alex for giving us his time and organising the event. It was interesting and very helpful. Also thanks to participants for enabling each other communicate easily with clarity. :) Best, Nehal On Fri, Sep 4, 2020, 6:05 PM George-Phillip Orais < orais.georgephil...@gmail.com> wrote: > Hi Olaf, > > Thanks for this recap, this is very nice indeed! > > I would like to add the hand-made block diagram by Alex for his > documentation, very cool!

Re: Philosophical implications of teaching PicoLisp
Thanks! I absolutely agree with you. What a depiction! For us, Lisp is just a way of dealing data in a different way (syntax) (with kids). We'll also be holding lectures in tribal schools, it's going to a fun activity for sure. Also the kids are experiencing a different life, things in an integrated way, math in art, art in Yoga asanas and Yoga in health/food. What matters most, is happiness in learning and smiles on their faces. Philosophy is living it in practicality.

Re: PicoLisp for 9-11 years' kids
Dear Mr Alexander, Thanks for appreciating our efforts. This was all unplanned and spontaneous. Infact we started to approach Lisp syntax with addition of numbers from 1 to 100. So all kids were focused on numbers. Syntax was just natural. The best thing was they enjoyed. And there was no fear of programming. At the end of the session they were told that it was Lisp and they can use Emacs Scratch Buffer for complex problems (they're already using Org mode for drafting journals to send us mails). Your response was forwarded to parents of these children. It was highly encouraging for them, seeing it coming from the creator of PicoLisp himself. We'll keep the PicoLisp mailing list updated about further activities.

Re: PicoLisp for 9-11 years' kids
Dear PicoLisp programmers, We have begun Lisp sessions here with kids. Many other kids joined. Without explicitly telling about symbolic expressions they learned to traverse, understand, solve lisp as mathematical puzzles. The session was taken by my mentor and co-worker, Alabhya Singh, Alumnus IIT Kharagpur. Session is in Hindi but explanation on board can be easily understood. You'll find videos of this interesting exercise here (in sequence): 1. VID20190425_lisp_1.mp4 https://yadi.sk/i/KRSwiQGyt0FxNw 2. VID20190425_lisp_2.mp4 https://yadi.sk/i/CrhU6naCuhfTtQ 3.

Re: PicoLisp for 9-11 years' kids
Hi everyone, Thanks for responses. Indeed this website is wonderful. However I am looking for something only based in PicoLisp. Thus I would make such snippets and share beautiful things here for everyone. It seems there are other people looking forward to introduce Lisp to children at an early age. It would be great if we can give something amazing in PicoLisp. Thank you.

Re: PicoLisp for 9-11 years' kids
Hello, Thanks for your detailed response. My focus is initiating them in PicoLisp. Also these are young, bright children who are in homeschool, are of 9, 11 ages and will just begin baby steps in Computer Science. All I want is KID LEVEL CODE SNIPPETS. Discussion over IRC is a good idea. What time will be best?

PicoLisp for 9-11 years' kids
Dear PicoLisp programmers, I'll be introducing PicoLisp to two young exceptionally bright sibling children (Ojas, boy age 9 years and Oshin, girl age 11 years, who are in homeschool) who have no experience of computer science and programming. PicoLisp being the most advanced computational framework and perfect model language suits best for this purpose. Migrating from one language to another becomes a tough job later in life. Such as children knowing Sanskrit/German as their first language will find them easy than people who learn them later in lives after already speaking English (or any other language for that matter). I'm very excited to begin this as it is a radical approach and is extremely challenging. I am considering what and how I should start. And at what stage should they be introduced to C and Assembly? I want them to get idea of PicoLisp as the language for handling all their day to day projects that they'll be needing to do in coming days, and later in life. I also plan to introduce PicoLisp in local communities and schools depending on my experience with them. You may be aware that proponents of other Lisps such as http://www.racket-lang.org are putting lot of effort with beginner level, easy to programme colorful pictures, animations and graphics to provide lively introduction to young students to introduce their language as first language early in their lives, even as a tool to learn elementary Math, Science and also to make beautiful presentations. Children will find it extremely attractive if they can create something out of PicoLisp, like diagrams, presentations, Math (using svg library to make geometric shapes, plot graphs etc). These are some of my ideas that I'll be trying to implement. Yet I'll also be needing help of other PicoLisp programmers in this regard. Active cooperation, reviews, feedback and suggestions are welcome. Best, Nehal

Re: Wiki progress update ...
Hi Arie, While observing new changes made in picolisp wiki css, I observed on https://picolisp.com/wiki/?PCE: 1. *Numbering* error of headings. 3 comes after 4 again! 2. "On Rosettacode you can find a wealth of examples on a huge *scala* of common programming problems." Perhaps you wanted to write 'scale'.

Re: Wiki - asking for last calls on fonts etc.
I agree with Alexander. Base font would be better if bigger as before. I don't have much issue with look and feel of italicized content but base text be bigger (also with bigger base text italics may have to redefined). The earlier wiki settings were also great and only some categorization of articles was required. I got extremely occupied in other things and couldn't focus on organization in last months here however it was well placed in my mind. With further suggestions from Mr Burger, I think we should focus on giving quality articles that are well managed and organized. Fonts, look and presence were great even before. I have also not followed this discussion closely. So if this is being done with collective decision making then it may be ok to continue with improvements. I'll be happy to contribute in any way I can. :) Regards, Nehal सा विद्या या विमुक्तये On Mon, Jun 25, 2018, 7:10 AM Alexander Williams wrote: > Hello, > > I haven't been following the recent website changes, but right now it > seems the picolisp.com website is much worse than it used to be.

Dear Christophe, Thanks for such an overwhelming response. 1. I am glad you could get chance to view the doc and give me further suggestions. 2. I have started to read Emulisp too. 3. I wanted to understand your website microalg.info, so I started with certain French learning books/cheatsheet too this morning. I did some French back in graduation days. It was great to come back to French after a long long time. I also felt that Sanskrit knowing person will find French easier to grasp and understand. :) So now I should be able to merge deeper into microalg.info and further write to you after understanding things well. 4. Thank you once again for pointing out various URLs. I have started studying.
