The Lounge

@Kent-Dorfman Yup That is also Correct. I am not in college and I am self-taught till now. I just do it for fun. And just helping peoples for free. And not obviously PRO at it Online forums have become a haven for workers under cheap-A$$ managers who hire folks without the domain knowledge to do broad design Yup that is truth.

@eyllanesc & mzimmers > prior to seeing your reply (eyll...) I did "a clean slate" try without any problem. I seem to have become entangled somehow : in addition to the zipfiles in the main (non-build) folder I had QtQuickCalculator.pro.user, [QQC].qml and [QQC]Form.ui.qml - beats me what I did! Also had main.qml under Sources rather than Resources/. Groan. Sorry to have unnecessarily bothered people with my own stupidity. This deserves a [DELETE] rather than a [SOLVED] I think.

@JKSH ...and your attitude to blame it on me - I did not write it well - is so common and stinks

@AnneRanch said in General question about open source development: @JKSH So if the "author" has no obligation to publish - how does that "protect" the user ? If it is bad product I can see the "protection" , but it should be up to the user to decide. In any case - there is something amiss in the concept of "free licensing" - it is like writing a book and not publish it. Silly. You'll find there's nothing amiss when you understand its goals. If an application/executable is a house, and the source code is the blueprints, then a traditional commercial license is like a property developer that says: "Pay me money and you can live in this house. But you are not allowed to look at the blueprints, you are not allowed to renovate or repair the house, and you are not allowed to replace even a single lightbulb." Now, suppose someone invents a fancy home automation system. If this system is released under the GPL, it says to the property developer, "You can use my system in the houses that you build. In return, you must give your buyers the blueprints (including the schematics of my automation system) and give them permission to renovate/repair/replace all parts of the house." If this system is released under the Lesser GPL, it says to the property developer, You can use my system in the houses that you build. In return, you must give your buyers access to the schematics of my automation system and give them permission to tinker with and replace the automation system. So, when the inventor releases the home automation system under the GPL/LGPL, they are encouraging property developers to give the homebuyers more freedom.

@Kent-Dorfman Biker bar ? If I own, not ride, Huffy -will you let me in? ( See it is all in definition - "lounge" included ) I am not sure about reaction to this - czech lounge @ code project...

@KroMignon Thank You But I really hope everyone to reply like you did on the last one. I am learning QT since 1 years So not pro at it. So may be you could have corrected my question. Like in last one. And sorry for not telling everything in the question. Will do this from next time Thank You Sir 😀🤘

thanks for it @Cronin

@yalnte said in Qt elevator pitch to IT: To get Qt installed on my system I need a link to a self contained full installer and a clear rationale as to what LGPL means and what the licensing terms are. This used to be a lot easier in the olden days! If you don't need the latest and greatest, the direct link to the Qt 5.12.11 LTS offline installer (released just last month) is at https://download.qt.io/official_releases/qt/5.12/5.12.11/qt-opensource-windows-x86-5.12.11.exe Clear rationale to what LGPL means in your case: Your app must clearly acknowledge the use of the LGPL library and provide the full text of the license. Your app must use the LGPL'ed library in DLL form, as opposed to statically linking it into your app. (Technically there is more to this story, but if you just stick to DLLs everything will be fine and simple) You must offer to provide the full source code of the LGPL'ed library. (A copy of the code is in the installer) You don't need to provide the source code of your app. The nice thing to do is to contribute back to the community of the LGPL'ed library in some way (e.g. helping out in this forum, submitting bug reports, submitting patches to the library, telling people about the library, etc.) This is not a legal requirement, but it is the nice thing to do since you're getting the library for free. That's it, really. elevator pitch "Qt is an intuitive, cross-platform toolkit that blows its competitors out of the water. Qt-based apps are easy to write and easy to maintain*. It provides all kinds of functionality, from GUIs to 3D image rendering to networking to database access, and more -- all in one coherent package." (*assuming that the programmer follows best practices)

@JonB If there is developer mode enabled with windows insider program Then you will get updates regularly and takes much time too. Before I hadn't enabled developer mode and not joined windoz😆 insider The updates takes much less time. And updates use to come slower than now

QByteArray is a simple std::vector<char> with an explicit \0 at the end.

Oops...didn't think anyone would care about that... my very own bug report

Random thoughts: I've read an article recently that people on average are superb predictors of probabilities, if the prob. density is symmetric. We fail rather miserably when the statistics is very skewed though. I found this very interesting - we tend to identify and predict additive factors excellently by intuition, but we are not so good when the dependency is multiplicative ...

@Chris-Kawa said in C++ question: But that's excessively verbose, at least for me. Also there's the Qt-style naming: constBegin(), constEnd(), which is my personal preference. And while I support the idea of using a range-based-for, that's useful whenever the iterator is simple (e.g. a glorified C pointer). If you're iterating a map, you either are stuck to explicitly iterating over or going to a structured binding syntax (which I personally despise).

@fcarney Well said. Nobody in right mind expect perfect communication, but forgetting the purpose of the forum - to solve issues . and let managing take precedence is what i am ( little ) concerned about. I see how monitoring for spam became game of moving stuff around on a whim. But I have to give a credit - no other tech forum does that. Something like "...line up alphabetically by size..."
