And I too love it :) (in my case it's both Squeak and Cuis) </div> <div><br> </div> </blockquote> <br> I discovered Smalltalk in 1995. By that time, I had been programming for 10 years. After the obvious (at that time) start with Basic, I quickly moved to 6809 Assembly and did pretty advanced real time music stuff. Then, I moved to C, as a kind of "portable Assembly". When C++ seemed to take over the world, I assumed it was the obvious next step. Up to this moment, I had always learned by myself, reading books and experimenting with the computer.<br> <br> This approach failed completely with C++. I read 3 or four books, cover to cover. I did a lot of experiments, and could not see the value. Never understood the "TurboVision" library. I did value what is called C+, that is statically determined "polymorphism" based on parameter types.<br> <br> Then, I was lucky. I was around 3rd year in my CS studies at UniBuenosAires. An elective course called "Object Oriented Programming" was offered. I knew that was what I'd failed to grasp with C++, so I signed up for it. The teacher, Máximo Prieto changed my life forever, as he changed the life of may of us then. He introduced us to Smalltalk, and the whole idea of dealing with complexity. He also started the thriving Smalltalk community in Buenos Aires. Today Smalltalk is taught at several universities here, there are several companies using it for real product development. Buenos Aires is the main source of Smalltalk talent for almost all the Smalltalk systems currently in active development, not just Cuis.<br> <br> So, I don't know how it is to discover Smalltalk without a great teacher!<br> <br> <blockquote cite="mid:emdf674052-de16-488c-9f39-64399d037a85@94dd308b.com" type="cite"> <div>> Early in my learning I had a lot of beginner questions for which I failed to easily find answers. [...] and there is a high expectation that beginners will read through the source code and try hard to find answers on their own. </div> <div><br> </div> <div>I so much share your frustration! In my experience no amount of reading the code can replace guidelines from experienced users enlightening the **intentions** behind the code as some parts of the code are just implementation details and trade-offs while some other parts are the "good stuff", bear the ideas. But which is which?! This is where I struggle the most, to be able to extract the ideas and filter out the "noise", and where I consider expert advice irreplaceable. And this is one of the things I'd love to find in comments. </div> </blockquote> <br> I think it would be best to take a Smalltalk course with great teachers. I know, I know, that is even harder to find than good developers for your Smalltalk project (unless you look at Buenos Aires!).<br> <br> What is next best to that? I think that Dan Ingalls' "Design Principles Behind Smalltalk" is the best presentation of the ideas. I can't stress how important it is to read it and really try to understand it. There are many other good introductory books on Smalltalk, all freely available on the web. Adele Goldberg's "Smalltalk-80, the language and its implementation" is great. There are several others, including our own "The Cuis Book" by our friend Hilaire Fernandes. In the Documentation folder of our mail repo you can also find some good material, including lots of references for further reading. There are also many videos online that will help.<br> <br> Books, magazine articles and videos include descriptions of the ideas and intentions behind the code that are generally better than answers in the mail list, because they were written with great care. Questions on the mail list are better for filling in details, especially if they are specific to some dialect (like Cuis) not directly addressed in the book. For instance, this email is taking an hour to write, and the mail thread leading to this has had me thinking at least 5 times more. Maybe I'd turn this email into an .md document for the Cuis repo. Then, will people read it?<br> <br> <blockquote cite="mid:emdf674052-de16-488c-9f39-64399d037a85@94dd308b.com" type="cite"> <div>> So I frequently asked questions on this mailing list. Over time I learned that doing that is frowned on [...] While some in the community may have been annoyed by the number of questions I have asked [...] </div> <div><br> </div> <div>I honestly don't believe it's the case! Otherwise I'd be afraid to ask next time :) </div> </blockquote> <br> Questions are most welcome. In this space we value free speech, and at the same time we want an open and warm place where everybody can feel comfortable.<br> <br> For any Open Source project, questions are especially valuable if they point to some aspect not covered in enough clarity and detail in the documentation. Good questions help us refine documentation, or fix annoyances in the system. You know, we old timers don't read the documentation we wrote very often, and we tend to get used to annoyances in the system to the point where we don't see them any more. Good questions, complaints and bug reports are extremely helpful!<br> <br> Still, questions that can be addressed by reading the documentation, or a quick query to the system can sometimes feel annoying, at least to me. I can carefully write some explanation, investing several hours, and making that part of the documentation. Or I can write 10 times about the same issue, when someone asks, each time improvising a low quality ten minutes email. The first option results in higher quality material, that can benefit many people over the course of years. The second option gives a low quality answer to just one person, that will most likely not be read again.<br> <br> So, if you read the documentation first, and then point to flaws or missing parts, you are really helping us make a better system. I can't stress this enough. I really, really, really, very much, prefer this!<br> <br> <blockquote cite="mid:emdf674052-de16-488c-9f39-64399d037a85@94dd308b.com" type="cite"> <div>> I really want to contribute via the documentation I'm creating and hope that at some point all of that content can be the basis for a book focused on Cuis Smalltalk. </div> <div><br> </div> <div>I wish you succeeded in this endeavor :) Again, my beginnings with Smalltalk were painful due to the lack of documentation and an availability of a vast knowledge base of the Stack Overflow type where you can sooner or later find a question similar to the one you're struggling with. I'm learning Rust at the moment and at least most of my beginner questions and confusion have been covered by the documentation so far. But I very much realize how much work it is to provide such a documentation and that it's only possible thanks to the size of the community; the amount of work to create (and maintain!) such a documentation is, I believe, about the same regardless of the language hence it's so much more difficult for small communities like Squeak/Cuis's where just a few individuals must carry the burden. </div> </blockquote> <br> While this is true, most languages and frameworks are what is called "black box". You only get the APIs or language constructs to use. If documentation is unclear or missing, your only resource is to ask someone for help. As Dan Ingalls says in his "Design Principles Behind Smalltalk", Smalltalk tries to offer a completely different experience. In Smalltalk, all the libraries are "white box". You are encouraged to see what they do. Time spent learning how to inspect and query the system is the best investment you can do in Smalltalk.<br> <br> <blockquote cite="mid:emdf674052-de16-488c-9f39-64399d037a85@94dd308b.com" type="cite"> <div>Quite recently I've discovered that the github Copilot can be a tremendous help in learning a language (accelerates learning the syntax, explains features and bugs, auto-fills simple examples and even more complicated code snippets - not always correct but even that helps!).

I know your code is clear, and with great comments. Still, if you ever feel like writing some .md documents on the stuff you know better than most, it would be a very welcome contribution!<br> <br> <blockquote cite="mid:emdf674052-de16-488c-9f39-64399d037a85@94dd308b.com" type="cite"> <div>Best of luck, </div> <div><br> </div> <div>Jaromir</div> </blockquote> <br> Cheers,<br> <br> <blockquote cite="mid:emdf674052-de16-488c-9f39-64399d037a85@94dd308b.com" type="cite"> <div x-em-replyforwardheader=""><br> </div> <div> <div>On 21-Oct-24 2:34:10 AM, "Mark Volkmann via Cuis-dev" <<a moz-do-not-send="true" href="mailto:cuis-dev@lists.cuis.st">cuis-dev@lists.cuis.st</a>> wrote:</div> </div> <div x-em-quote=""><br> </div> <div id="xc12625a08c154e0"> <blockquote cite="CAFfRWnU5xSpzwAoy0-LeoS0qra3zcBev_m8LNH-0+AKCR=fGKA@mail.gmail.com" type="cite" class="cite2"> <div dir="ltr"> <div dir="ltr">I apologize if the way I worded my question came across as rude. That was certainly not my intent. I think I should explain why I've tried to be a part of the Cuis Smalltalk community for the past eight months or so. <div><br> </div> <div>I'm pretty new to Smalltalk and it turns out I love it. And so far Cuis Smalltalk is my favorite distribution.</div> <div><br> </div> <div>Early in my learning I had a lot of beginner questions for which I failed to easily find answers. So I frequently asked questions on this mailing list. Over time I learned that doing that is frowned on and there is a high expectation that beginners will read through the source code and try hard to find answers on their own. I've tried hard to do that, but haven't always been successful.</div> <div><br> </div> <div>I decided that I wanted to help future beginners find the answers to all the questions I had more easily. So I started documenting everything I learned about Smalltalk at <a moz-do-not-send="true" href="https://mvolkmann.github.io/blog/">https://mvolkmann.github.io/blog/</a> (select Smalltalk in the left nav to see a long list of subtopics). As you can see, I have spent a large amount of time on this. It's nothing compared to those of you that have been contributing to Cuis Smalltalk for years, but I think it provides a good resource for anyone new to Smalltalk in general and Cuis Smalltalk in particular.</div> <div><br> </div> <div>I do not have a particular app in mind that I want to build with Smalltalk. Instead I'm constantly thinking about how I would convince non-Smalltalk developers to give Cuis Smalltalk a try. A perfect example of that is my investigation into database access. Many of the developers I know are web developers. Accessing relational databases is a fundamental part of implementing most web applications. So I need to be able to demonstrate how that is done from Cuis Smalltalk to have any hope of convincing my web developer friends to try it. As far as I know, based on many searches, there is not currently a web page that shows step-by-step how to access a relational database using Cuis Smalltalk. I want to provide that if I can learn how to do it.</div> <div><br> </div> <div>While some in the community may have been annoyed by the number of questions I have asked, I do hope there is a feeling that my presence in the Cuis community has had a net positive impact. In addition to the documentation I've created in my blog I have identified a number of minor issues that have been fixed, contributed a small change set that added the ability to set a background image in cover and tile modes, and most recently contributed a library for implementing web servers that has many advantages over the WebClient library (<a moz-do-not-send="true" href="https://github.com/mvolkmann/Cuis-Smalltalk-WebClientPlus">https://github.com/mvolkmann/Cuis-Smalltalk-WebClientPlus</a>).</div> <div><br> </div> <div>I really want to contribute via the documentation I'm creating and hope that at some point all of that content can be the basis for a book focused on Cuis Smalltalk.</div> <div><br> </div> <div>P.S. I honestly didn't know that the Cuis-Smalltalk-Dev/Documentation/Technical directory existed. Thanks for pointing that out. I'll read that now.</div> </div> <br> <div class="gmail_quote"> <div dir="ltr" class="gmail_attr">On Sun, Oct 20, 2024 at 5:48 PM Juan Vuletich <<a moz-do-not-send="true" href="mailto:juan@cuis.st">juan@cuis.st</a>> wrote:<br> </div> <blockquote class="gmail_quote" style="margin: 0px 0px 0px 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> <div bgcolor="#ffffff"> Hi Mark,<br> <br> What follows may be an intricate reading involving language, manners, and how the Open Source world works.

Cuis Smalltalk is MIT license you get the whole system, free for any use, without any obligations. That means that you are not required to disclose what you do with it. As a consequence of that, the answer to "it is possible that nobody that uses Cuis Smalltalk does XXX?" is true, for any XXX. Does this matter? I don't think so. <br> <br> A much better way to react would be something like "Hi Folks. I'm trying to do XXX. I know the system is fully open and explicitly designed to make it easy for me to solve my technical problems, but I'm still unable to do so. Has anybody faced these kinds of problems I'm seeing before, and is willing to help me?". <br> <br> That will indeed work much better.<br> <br> Additionally, some comment from you revealing that you have already read the contents of the /Documentation/Technical folder would be appreciated. Your first message made me believe you hadn't realized you had trouble calling an API via FFI. But Jon's answer doesn't tell you that, and assumes you already know that. Your following message makes me now believe that you know that the problem may be "how to reference a lib path in the Open Smalltalk VM", indeed being aware that this is a problem with FFI. <br> <br> Once you realize that, you may also realize that this problem has almost nothing to do with Cuis Smalltalk. A bit of googling shows people asking similar (but better formed) questions in nginx and lua. <br> <br> I'm starting to have doubts about your intellectual honesty while asking these questions.
