A: Should "Hello", "Thank you", "Morning" and similar greetings be removed from posts? Just to have a differing viewpoint represented. Addressing questions and answers The stated reason for stripping politese Somewhere Else (which I largely agree with) is that while posts are created and improved as a human interaction, their main function is as a long-lived informational resourc...

A: How do I communicate with a subproject in qmake? Options There are three basic channels to choose from Shared build-include (`.pri`) files `CONFIG` `.qmake.conf` and I discuss the practicalities of each below. Shared `.pri` files Set or add to things like `INCLUDEPATH` or `DEFINES` that should affect your whole project in a `.pr... (more) |

How do I communicate with a subproject in qmake? When working with a qmake subdirs project you may want to share configuration between multiple projects. In a less common case you may including a external project within your own as code and want to configure the build of the included project. Either way, the solution is to communicate decisions ...

A: Write to same file from multiple threads Because you are using Qt in particular there is something to be said for not solving this problem yourself. Instead, create a single object that owns the stream or file and offers a `writeLine` slot. In the simplest case the signature might be `writeLine(const QString & line)`. Then your threads s...

A: Are code troubleshooting posts allowed? tl;dr: Allowing beginner-level "help me diagnose this" questions will generate large volumes of duplicates if the site ever scales. We need to think about how to structure things if we want them. I have certain reservation about this. I've said before that I don't think question-and-answer ... (more) |

Scheme for cross-platform warning control? []()tl;dr I'd like to learn a compact, cross-compiler way of selectively suppressing compiler warnings. Consider the case where you really mean to make an exact floating-point comparison using `==`, or the case where you capture a return value that you don't use in production but want to `asse...

A: Do we need the fullstack tag? This is another argument for a fullstack tag not being appropriate. Or perhaps an elaboration of Peter's argument. The manner in which a problem could be a "fullstack problem" is by being a communication or coordination problem between tools running at the front end and at the back end. In that... (more) |

A: Is omitting braces for single statements bad practice? I'm in the "Use the braces. Just use them every time" camp [^1]. As others have suggested you or your tooling will catch a lot of cases where you screw up on this, but the ones that slip through can really hurt. So, I was surprised to hear Robert "Uncle Bob" Martin opine that he's "on a mission to... (more) |

I object to [stl] Currently the tag [[stl]](https://software.codidact.com/categories/38/tags/3925) is marked as a sub-tag of c++, implying a meaning of "standard-template-library". However I see both of the questions currently using the tag mean the 3D object description format). As I see it both meanings are relev... (more) |

A: Are reference requests welcome here? Just to stir the pot a little, on Physics SE we ended up allowing them within certain limits. Though I was against it I would say that the results were rather better than I expected. We did set up a post notice for the category that reads: > Before answering, please see our policy on resourc... (more) |

Pros and cons of various type_traits idioms My work tasks have recently started requiring me to use the `typetraits` header to restrict the classes that may be used in template functions, methods, and classes. And while I used it for a long time now, I learned C++ on the job. I've seen at least four patterns (see below) for actually coding ... (more) |

A: For scripting what are the pros and cons of command line arguments versus capturing input at the start? I'd like to move the frame out a little and use that as a discussion for how to make these decisions. Input models You've listed two input models, but I think we need to add a third before we begin. I'm going to call them 1. Command line arguments 2. Interactive read at run-time 3. Non-int... (more) |

Add link dialog should capture enter I think we have a UI problem with the "add link" dialog box in the editor: it doesn't capture enter keystrokes which then fall through to the submit button. > I'm merrily typing a post when I realize that it would be improve by linking a phrase. So, I copy the link, highlight the text, click the L... (more) |

A: What gets allocated on the stack and the heap? While Lundin has written a reasonably complete answer, I think it suffers a bit from the expert view: conflating core issues with implementation details related to modern hardware architecture. I'd like to try to separate these notions. Kinds of variables To start with I'm going to divi... (more) |
