    "This thread is old. Do you want to start a new one?"

    That means that thread is really old :) Maybe you need non-newcomer permission to re-open/un-necro an old thread! You should be able to create your own, and reply in that and other current threads. The only thing is I understand you have to wait like 10 minutes between posts if you are new. I don't know when that goes away --- either after so many posts or so much time, or like I said my previous "upvote" may help you :)

    It used to bugged me too, so I checked and I can sleep better since, knowing that it's just the usual case of too many cooks in the kitchen, as often is with standards that evolve over many decades.

    QML colors are derived from CSS colors. CSS is a resulting combination of loooong browser wars from the beginnings of the internet. Different browsers supported different color sets, then they tried to become more compatible with each other, there was some mix and matching, compatibility shims etc. etc. and at the end a weird combination of couple of sets was standardized in CSS.

    So basically what happened with shades of grey is that the standard grey comes from HTML and is defined to be 50% brightness, while darkgrey is at 66% because it comes from the X11 color set in which grey was 75%, resulting in this silliness.

    Just take a deep breath and let it go. In the end they are just words assigned to some values. It doesn't really matter. Nothing does. We don't either. At some point an asteroid will hit Earth again and all of this nonsense will go away ;)

    @JKSH thanks for your reply. You are right with account.qt.io to be the central place for such a modification. Actually there is currently no option to make that change ourself but one can create a ticket asking for the modification.

    It's just been moved into "Additional Libraries" section

    However it has been moved.

    @sierdzio said in Future of Qt3D:

    KDAB is the developer and maintainer of Qt3D and they have not announced any deprecation of it.

    They have not announced deprecation but you can watch the repository activity is getting worse https://github.com/qt/qt3d/graphs

    But I wish the project active development. Indeed, it has no alternatives in Qt.

    @SGaist My sharing of same RAID between different OS - all Linux - is a side issue. It appears that .pro uses the "path" - which is normal but if the .pro file was build using different mount point of the RAID - QT cannot access it.
    In other words - the "mount point" is part of the QT build path and it has to match . I am still looking "ownership" of the RAID.
    Definitely not QT problem.

    Do you really need all that info ?
    " I added my perfectly working QT project partition to the WORKING array..."
    The add can be half deleted from the array - only half because it cannot be physically removed - it is a partition, not a disk.
    Then the file should be changed back to "etx4" - not "linux-raid"....

    But it gets too convoluted...hence I am abandoning the efforts to recover the data.

    @kshegunov said in is it ethical ?:

    At least to me, which I believe is @Kent-Dorfman's point too, a business has one purpose to exist (one purpose to rule them all, if you will) - to make money for its owner.

    I agree that a business' primary purpose is to make profit too. I don't agree that this primary purpose should be pursued at all costs.

    @Kent-Dorfman's argument is "Behaving ethically reduces profit, therefore ethics has no place in business." This is quite different to your argument that "Ethics does not apply to entities that are not natural persons".

    Businesses already do consider not killing people, mostly. Elsewise they run the risk of getting forcefully prosecuted and terminated.

    Precisely. This shows that ethical considerations are codified in law and applied to businesses, no? (I'm presuming that you agree that "Avoid injuring or killing people" is ethical. Same goes for "Always use accurate scales for your customers, never rig scales" and even "Don't pressure your staff into begrudgingly working unpaid overtime".)

    Anyway, the key phrase in my robot example was "even if taking those steps increases the costs... and cuts into profits". In other words, the primary purpose of making money can and should be guided by other (ethical) considerations.

    I don't consider a business to be a cohesive single-minded entity, nor that you could assign social attributes to it.

    ...

    I guess, if you consider ethics a category applicable to legal entities, which I (still) don't.

    That's OK. Regardless of our difference in opinion there, can you accept the following?

    A business can be run in an ethical or unethical manner (Example: using rigged scales to unethically increase profits vs. using accurate scales always). A business should be run in an ethical manner even if it means less money is then made as a result.

    'Cos I don't care whether or not it makes sense to stick a label on a business/company. I care about the side-effects of the business' money-making process.

    consider something terrible, like a coal mining company, shall they run their operations for free as coal is the terrible industry killing thousands of people worldwide (mostly indirectly)?

    If a business is proven to contribute to deaths, then how much it charges for its services is irrelevant. At the very least, it needs to take steps to reduce those deaths, pronto. If it won't do that voluntarily, then it is continuing to operate unethically so the law and/or society needs to ensure that continuing as-is leads to the business "getting forcefully prosecuted and terminated" (Shegunov, 2021).

    It ain't sustainable by your definition, shall we close all of them, or condemn them somehow from our warm(-ish) coal-powered homes?

    Short answer: If an action reduces those deaths, then let's pursue that.

    Long answer: Coal dependence and its effects is a wicked problem that can't be solved in a forum post. When I mentioned the "interests of a multitude of stakeholders" before, that list here includes the towns/communities whose existence currently depends on the operation of the coal mine, the people who currently depend on burning coal to avoid freezing in winter, the people who are currently losing their homes/livelihoods/lives to the changing climate that coal extraction+use is contributing to, among countless others.

    So is it ethical to have a mining company to begin with?

    I don't understand this question. Care to clarify your underlying question?

    Also consider a company that makes/sells explosives, weapons, digs for anything basically (same concerns as with coal), sells medical equipment (imagine you need it, but you don't have enough money to pay); the list goes on forever.

    "the list goes on forever" -- This has no bearing on whether or not ethics apply. "Ridiculously difficult" != "Shouldn't do".

    alternatives is a front end for simply replacing the /usr/bin symlinks. You can make /usr/bin/python point to whatever version you have installed. I'm in upgrade to python3 hell at the moment because I installed debian 11 on my newest workstation and I need to make it backward compatible with bunches of NFS shared python2 programs I run interchangably on other machines. of course many of those apps use python2 specific modules that aren't available in debian11.

    @AnneRanch giving proper credit to library authors and doing advertisements are two different things.

    The credits shall be easy to find i.e. an about box. It's nowhere written that you have to be prominent about which framework you use.
