Who is using Qt5?

[BKBK]

Does anyone know of U.S. government facilities that are using Qt5? DoD preferred.
Some portions of the government have changed their rules since the early versions of Qt. Their rules now state that software from foreign owned companies cannot be used. We are allowed to use what we have but cannot update. However, there are methods to get approval. If I can find government entities that use Qt5 then the possibility of getting our work group updated is greatly improved. Not guaranteed, but significantly improved.

This is about installation, but maybe not. Should it be in the general discussion forum? If so, moderator, feel free to move it.

@BKBK I don't know whether any government facilities use Qt.
You should actually mention which government you mean.

hi @BKBK

if you take a look at this wiki article
https://wiki.qt.io/About_Qt#Facts_and_Figures

You'll see a list of companies and organizations that supposedly use Qt in some form or fashion. Including some government institutions

How accurate that is, no idea.

You may have to contact the folks directly. As your request very well may lead to lots of licenses, chances are high you get an answer quickly ;-)

@jsulm Good point. I often forget that. United States government.

Qt is open source. Qt Company does not own the project - there is an agreement with KDE that if Qt Company ever "goes bad" and closes Qt source, KDE will automatically take the code over and keep it open source.

@sierdzio
From my perspective, and my presumption is that, those in the cyber security group who make the rules are concerned that there may be a bad actor in the software team who creates Qt and they may put in something malicious.
I have no information upon which to make a judgement as to if that bad actor probability is higher for non-U.S. coding teams as compare to teams within the United State. And I strongly suspect that my judgement on this matter would carry no weight what-so-ever.
I am aware that Qt is open source. Being open source does not guarantee that someone has closely examined all the code for malware.

@BKBK What is the policy of your government/cyber security group regarding usage of open source software?

"Being open source does not guarantee that someone has closely examined all the code for malware" - correct, but without source code there is guarantee that nobody outside the company writing the code examined the source code :-) From my point of view organisations concerned about security should either use open source (to be able to check source code) or have special agreements with companies to be able to check source code from closed source software.
