Re: [Oberon] Accessibility of FPGA configuration to V5 system.

Of course the mechanistic approach us just as valid for a biological system as for a bridge. The difficulty with a biological system is the complexity. Illustrated here. https://www.janelia.org/news/unveiling-the-biggest-and-most-detailed-map-of… https://www.biorxiv.org/content/10.1101/2020.01.21.911859v1 Note the large Zeiss microscopes working for more than a year to complete the mapping. The brain of a fruit fly has about 100 k neurons. Comparable to the LUT in a contemporary FPGA. Striking that the fly brain is approximately the size of a poppy seed while a FPGA board is 10^5 - 10^7 times that volume.

Not particularly related but comparison interested me. The fly successfully implements aroma detection, vision, navigation, flight, ambulation, ingestion, reproduction and other activities. Likely some activities are learned rather than innate. The configuration of the fly nervous system is adjusted as the fly develops. In comparison, configuration of current FPGA machines is not changed while software runs. In fact the fly doesn't separate logic, volatile memory and persistent memory. Optical sensors (eyes) and aroma sensors (chemical receptors) are distinguishable fairly easily. Regards, ... P.L. -- mobile: +1 778 951 5147 VoIP: +1 604 670 0140 48.7693 N 123.3053 W

WorkLog under BlackBox
by Aubrey McIntosh 09 Dec '21

09 Dec '21

I have created the repository at git@github.com:a-mcintosh/WorkLog.git This contains 2 BBCB modules. *History* is a factory module that supports timestamped events. It may be extended, for example, to save a timestamped series of variable values during program execution, particularly during development. I am running the Denisov release under Ubuntu. More specific details in the opening reading matter in the git. *WorkLog* extends the structures for *History.Entry* to contain an additional timestamp, and a 64 character nickname for the current task that you are working on. This is a minimalistic application. It would be greatly enhanced by an interface into SQL, for example. I request several things: - Advise me of the current standard process to submit BBCB subsystems. - Have a look at the code, in particular the *Services.Action.Do <http://Services.Action.Do>* extension in WorkLog, with a view of having the Panel update after *LogIt* has executed. - Suggest ways to actually use the Internalize/Externalize procedures. I assume that the suggested path is to embed a WorkLog view (currently undefined) into a Text or other View and let the Framework handle the details when the View is saved from a window. Are there other ideas? - In general, especially those of you who have taught CS, feel free to be aggressive with critique of the code. That is how I learn. No aspects are out-of-bounds. - I suppose that somewhere, someone has written a similar thing. This is a "keep-my-skills-up" project and I don't care if it is already done, but I'd like to read any such code. - If any Obx addresses relevant concerns, please alert me. I read through them from time to time. Thanks -- Aubrey McIntosh, PhD

Fwd: [FOSDEM] FOSDEM 2022 - Declarative and Minimalistic Computing - Call for Participation
by Liam Proven 02 Dec '21

02 Dec '21

The invitation below sounds like it might be something of interest to some people in the Oberon community. I am not sure that I have a lot to usefully contribute myself, but perhaps I can try to get some of the old Oberon for DOS code working... Anyone interested? -- Liam Proven ~ Profile: https://about.me/liamproven Email: lproven(a)cix.co.uk ~ gMail/gTalk/FB: lproven(a)gmail.com Twitter/LinkedIn: lproven ~ Skype: liamproven UK: (+44) 7939-087884 ~ Czech [+ WhatsApp/Telegram/Signal]: (+420) 702-829-053 ---------- Forwarded message --------- From: Manolis Ragkousis <manolis837(a)gmail.com> Date: Thu, 2 Dec 2021 at 09:23 Subject: [FOSDEM] FOSDEM 2022 - Declarative and Minimalistic Computing - Call for Participation To: <fosdem(a)lists.fosdem.org> Cc: Guix Devel <guix-devel(a)gnu.org>, <guile-devel(a)gnu.org> We are excited to announce a devroom on Declarative and Minimalistic Computing at FOSDEM on 5th and 6th of February, 2022, online! FOSDEM is one of the most important free software conferences and is hosted annually at Université libre de Bruxelles in Brussels, Belgium. Unfortunately again this year FOSDEM will not run a physical conference but will be online only. Talks will be pre-recorded with some live content including Q&A sessions and discussion panels. We accept talks from languages that attempt to minimize use of hardware and software while trying to make systems simpler, more robust and more secure. If you are working on improving today's systems taking declarative/minimalistic approaches feel free to submit a talk proposal. Examples include the Scheme/Lisp family of programmings languages. In past editions, this devroom has received presentations from a varied number of language communities, including Forth, Guile, Lua, Nim, Racket, Raku and Tcl as well as several experimental projects that push minimalism in new directions. Minimalism and declarative programming are two important topics for this devroom. Minimalism matters. Minimalism allows for smaller systems that take less resources and consume less energy. More importantly, free and open source minimalism allows for secure systems that are easy to understand. Declarative programming is a programming paradigm that expresses the logic of a computation without describing its control flow. Many languages that apply this style attempt to minimize or eliminate side effects by describing what the program must accomplish in terms of the problem domain, rather than describe how to accomplish it as a sequence of the programming language primitives. Finally, in this year's virtual conference we will honor the late Professor [https://en.wikipedia.org/wiki/John_McCarthy_(computer_scientist) John McCarthy] as the founder of AI and the inventor of LISP. McCarthy with his work pioneered artificial intelligence, developed the Lisp programming language family and kickstarted our modern computing world. We want to invite you to submit a talk on declarative and minimalistic computing that fits that description. We are especially happy to receive talk submissions from members of groups underrepresented in free software. If you have something you’d like to share with your fellow developers, please E-mail us! Talks considered for the devroom will have to be entered in - https://penta.fosdem.org/submission/FOSDEM22 The deadline for submission is December 20th. If you have a FOSDEM pentabarf account from a previous year, please use that account. Otherwise add one on https://penta.fosdem.org/user/new_account. Reach out to pjotr.public456(a)thebird.nl or manolis837(a)gmail.com if you run into any trouble. When submitting your talk make doubly sure to select "Declarative and Minimalistic Computing devroom" as track (if you don't we won't find it), and include the following information: * The title and subtitle of your talk * A short abstract of one paragraph * A longer description if you wish to do so * Links to related websites/blogs etc * Presentations has to be pre-recorded and streamed before the event. * Start recording early! To see what a final talk looks like see https://archive.fosdem.org/2021/schedule/event/gnumes/ For accepted talks * Once your talk was accepted, we will assign you an organizer to help you to produce the pre-recorded content. * The organizer will review the content and ensure it has the required quality. He is also responsible for ensuring the content is into the system and ready to broadcast. * During the stream of your talk, you must be available online for the Q/A session Let's make this a fun day! = Organizers = Pjotr Prins, Manolis Ragkousis, Ludovic Courtès, Amirouche Boubekki, Hisham Muhammad, Jan Nieuwenhuizen, Ricardo Wurmus, Alex Sassmannshausen, William Byrd, Oliver Propst, Efraim Flashner, Julien Lepiller = Code of conduct = - https://fosdem.org/2022/practical/conduct/ = Original proposal = - https://libreplanet.org/wiki/FOSDEM2022-devroom-proposal = Important dates: = - Dec 20th 2021: submission deadline for talk proposals - Dec 31th 2021: announcement of the final schedule - Jan 14th 2021: submission deadline for recordings - Feb 5th 2022: FOSDEM! = Links: = - https://libreplanet.org/wiki/FOSDEM2022-devroom-declarative-and-minimalisti… _______________________________________________ FOSDEM mailing list FOSDEM(a)lists.fosdem.org https://lists.fosdem.org/listinfo/fosdem

When I initialized the Computers table a few years ago, the headings including "Boot Store", "Memory" and "Persistent Store" seemed reasonable. Now I'm reviewing the table and imagining how it might be improved. Suggestions? Change organization? Add or remove content? Thanks, ...
