UK Smalltalk User Group meeting - Wednesday 29th March

by Giovanni Corriga

This month's online meeting introduces a new format whereby we'll give space to commercial companies to discuss how they make use of Smalltalk and contribute to the Smalltalk community. The first of this series will be Mercap Software ( https://www.mercapsoftware.com/en/ ), represented by Gabriel Cotelli, InÃ©s Sosa, IvÃ¡n Boaretto, MatÃas Fernandez, and Maximiliano Tabacman. During this talk, Mercap will showcase five of their solutions designed for different types of investors. They will shed light on how Mercap benefits from the open-source projects maintained by the Buenos Aires Smalltalk group on GitHub. They will share with you how they use these freely available frameworks to interact with databases, operate on math and time units, create custom CSS, declare interactions on web applications, display complex charts, manage application startup, and streamline the creation of Docker images. Gabriel Cotelli is a CS bachelor, continuous learner & free-thinker. Supporter of libre knowledge, human intelligence augmentation and open source software. Working in Smalltalk at Mercap since 2004. He's an active member of the Smalltalk development community and regular contributor to open source projects in Buenos Aires Smalltalk and Pharo. InÃ©s Sosa writes code in Smalltalk. IvÃ¡n Boaretto is a software developer by day and a computer science student by night. He is very passionate about his craft and is always striving to improve. Now, in his first time at the Smalltalks, he is looking to attract new blood to the wonderful Smalltalk community. MatÃas Fernandez is a software and tech enthusiast, and Smalltalk developer. Maximiliano Tabacman has been a part of Mercap since he started his studies in IT, which now include a PhD in Computer Sciences from the Facultad de Ciencias Exactas y Naturales (UBA). His main interest is the design of systems that apply nature inspired concepts, such as evolutionary algorithms and neural networks. Smalltalk, with its object-message design, is his natural choice for a development platform. He is also the creator of ERA, a standalone web server application for running table-top roleplaying games, which runs on Windows, Mac and Linux. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/292128721/ ) to receive the meeting details.

Re: Wow - Chat GPT understands Smalltalk

by Offray Vladimir Luna CÃ¡rdenas

I agree with Richard. The Turing test is not a good one to test intelligence and we have now just over glorified Eliza chatbots that appear to think and to understand but do none of them. There has been long criticism to the Turing Test, like John Searle's Chinese Room (I recommend to listen completely the talk at [1]). It is good that ChatGPT can explain simple (Smalltalk) code, but it doesn't understand it and all the language most are using conveys a lot of deception: "machine learning" (I called machine training), "artificial intelligence" (I wold called algorithmic decision/generation), or the "thinking" message that is used in the referred code explainer, when something like "processing" would be less deceptive. [1] Consciousness in Artificial Intelligence | John Searle | Talks at Google https://www.youtube.com/watch?v=rHKwIYsPXLg With Pharo/GT we are part of a long "explainable systems" tradition and with "AI" / Algorithmic Decision/Generation, hopefully we go to explainable AI, instead of a world of impressive black boxes.

Monticello files AFAIR are zip files.

Re: searching for pharo code on disk

May have some syntax wrong, but something like: find . -name *.changes -exec âgrep -i webscrap â Check the manpage of find command for exec examples. The -i on grep ignores uppercase/lowercase differences.

searching for pharo code on disk

by Siemen Baader

Hi, I'm looking for some code I wrote maybe 7 years ago. A web scraper that collected data from a specific web shop. It must be somewhere in my home dir in an image, perhaps Pharo 4.0, or in .mcz files stored by Monticello. What would be a good way to search for it? I tried `grep -r --include \*.changes "server-url.com" ~` (I also asked ChatGPT as per the previous discussion on this list, and it tries its best to teach me about grep and sound very convincing while providing me with arguments that grep can't evaluate :)) with no luck so far. Any ideas? Thanks, Siemen

Re: Wow - Chat GPT understands Smalltalk

by in_pharo_users＠nym.hush.com

I think smartness is not an argument to reject critique. The Imitation Game, that you describe, sounds to me like an even better setting. I have no dought that ChatGPT as it is now can identified as not human or even as a maschine. I did so by leading an instance for marketing purposes to hang in infinite recursion. But when we look at AI, we need to look not only at present features of one type of system, but at all features of present systems and their possible development and combination in the future. Especially I want to mention AGNs and the possibility of spawning parallel recursive processes. I am convinced that this kind of technology is allready being used in robotics. Under the control of a self aware AI in the sense that it has data about it's own capabilities and the ability to determine which capabilities it is missing to achieve a certain purpose, the evolution of the AI is only limited by ressources - which it will surely be able to detect. This must lead to a purpose of self preservation and the aquisition of such capabilities. It may soon find out, that ressources and redundance can be aquired by hacking and spawning agent systems, which in turn will give it control of real world control systems like telephony and data networks, cameras and sensors, energy networks and power plants, microphpnes, speakers, synthesizers and monitors, industry 4.0 fab networks, military detection and guiding systems, and so on. In my view this is what we are dealing with.
