Hi. I posted a Vulkan question on SO yesterday. That’s completely unrelated to you, but I suddenly came to think of Codidact, and that I made an account long ago. Now I wonder, if I was to ask that question here, on which subsite would I post it? My Vulkan question is not constrained to a particular language, so where would it go?

No I think we need a C community for that — and I think we should have one if there is any prospect of getting questions

I guess it is boost, multithreading, ranges, qt , network-programming or just networking … so it should be or specific widespread library or specific area maybe stl/ C++20 / templates. I’m also not fun about string or arrays tags. Maybe special tag homework.

Jack Douglas replying to GreenDragon — Wednesday, 6th May 2020 06:21

have you thought about what tags will be for in this community? SE goes a bit mad with tagging, and I think it’s best to add only ‘useful’ tags, i.e. things that people will likely want to filter a search on

Jack Douglas replying to GreenDragon — Monday, 23rd Mar 2020 21:43

that does sound more likely to work but I’m no C++ expert 😃

GreenDragon — Monday, 23rd Mar 2020 21:38

Well after a bit re-thinking, really this can be adopted to wide question about specific concept itself, so it will be valid. “Message passing between threads” (as common question) and “How Golang-channels can be implemented in C++” (and in the answers will be good to provide link for some OS libraries for illustration). But … sometimes it’s not always obvious and initial version of Q may be like “Channels in C++ how?” or something like that.

GreenDragon — Monday, 23rd Mar 2020 21:33

Yup, I am not talking about stuff like GUI (there are enough awesome lists on Github), only about rarely cases that could be interesting people with experience in other programming languages.

Jack Douglas replying to GreenDragon — Monday, 23rd Mar 2020 21:14

generally we want questions that lend themselves to one or two good answers, just like on SE — “what library that implements this concept” is generally unlikely to be that kind of question in general, but it may depend on the particular concept…

an hour
GreenDragon — Monday, 23rd Mar 2020 19:48

Are questions about libraries appropriate here? For example some time ago I was re-writing some application from Go where used channels. Therefore I wanted to find a library that implement this very useful concept. Quick search on Github gave me some options but other hosting service like Gitlab or less popular (like sourcehut that in alpha stage now) haven’t good search mechanism (maybe yet but still).

And of course some comments about use cases would be useful as well.

The exciting thing is that C++20 is bringing changes to a lot of the common answers. Rather than blindly importing we’re really able to improve in a lot of cases.

I’m not enough of a C++ user to write Q/A posts, but I’ve had enough exposure to do a set of Q’s, I think.

Hosch250 — Thursday, 27th Feb 2020 17:01

For example, I could ask how to write a safe copy constructor, or how to correctly open, read/write, and close a file.

Hosch250 — Thursday, 27th Feb 2020 17:00

Would it be appropriate to ask “basic” questions that I could find the answers to elsewhere on the web?
