How is one expected to use this library? It is custom for library APIs to have one "super header" including all other headers of that library, so I'd expect to find some "bmpl.h" and only include that one. (Note that "super headers" is generally bad practice except for front-end to large libraries.) ... (more) |

A: What compiler options are recommended for beginners learning C? My recommended beginner setup for gcc-like compilers is: `-std=c11 -pedantic-errors -Wall -Wextra -Werror` Here is an explanation of what these options do: - `-std=c11`. gcc & friends are by default set to include non-standard language extensions. These extensions are known as "GNU C" and ex... (more) |

What compiler options are recommended for beginners learning C? When reading questions about C programming from beginners, I very often see them describing peculiar run-time errors and crashes, segmentation faults and similar. They have spent a lot of time chasing down the bug but failed. Then upon viewing their code, I notice that the code should never have "... (more) |

If there's enough interest I could write another of them self-answered Q&A about how to do OO in C. Private encapsulation, setter/getters, inheritance & polymorphism. There's plenty of examples at SO but I find them lacking. I think I've written a few there myself too but I can't find them. (more) |

A: constructor in C The warnings just say that you can't pass a string literal with type `char[]` to a function taking a `struct Book` parameter. The function should be declared as: void initBooktypes (const char title, const char author, int pages); And in the constructor, `aTitle` needs to be `aTitle->title`... (more) |

@#53922 Depends on the context. During declaration of the variable, you can write `Node* ptr`, `Node *ptr` or `Node * ptr`, it's a matter of style. (the former 2 styles are most common). When _de-referencing_ the pointer to get the items it points at, you always write `*ptr`. (more) |

It's kind of strange that tags have case in the first place. I wonder if they were made that way on purpose. If so, we'd need to come up with guidelines for when & how to use upper case. If not, it just seems like a source for sloppy-looking tags. (more) |

I don't like Discord specifically simply for the reason that it's spyware. Scanning which programs you have installed on your computer and sending that information over the internet, for unclear and highly questionable purposes. It would good to have a chat room though. Is IRC still a thing? :) (more) |

Well I didn't even know there were tool tips before you posted this. Nor did I know SO had them on the voting buttons and I've been using that site for over 10 years... apparently my brain filters out such things as spam and doesn't register them. So changing/implementing them might not necessarily h... (more) |

My only concern is that it will seem like the site is just about Office questions and nothing else, it will momentarily "drown out" all other content. But the migration is just a single event, so maybe it should be done sooner rather than later. (more) |

Not sure if I'm following, sorry. Are you proposing that we change the tool tips when we mouse-over the vote buttons? Or are you asking if we should implement a specific page for this community to replace the default https://software.codidact.com/help/voting? Or both? (more) |

Well at this point it doesn't look like my proposal for that category is getting any strong consensus, so it's unlikely to be created any time soon. "Software Category" would just be the general Q&A on Power Users. For now, that's the most suitable place to move all those questions. But it will creat... (more) |

A: Can we migrate office suite related questions to the Power Users community? I went ahead and made a proposal on Power User that a separate category for office suites should be made. I suggest that we wait and see where that proposal lands. If a category for these questions is made, we can go ahead and migrate. (Such a category would also soften the "bump blow" that comes...

Kind of depends on how you define these terms. All of them go back to the earliest days of computing, in some form. Private encapsulation of autonomous "abstract data types" was around very early, long before "modern" OOP emerged in the 1980s somewhere. (more) |

@Monica Cellio No but they will be plenty and risk to drown out all the other content because of it. Just look at Power Users right now, someone dropped 10 or so questions about MS Word there. The same will happen when we migrate all office suite-related questions from here to there. (more) |

Better wait until their scope has settled. If we are not launching an office suite community then it would make lots of sense for Power Users to create a category for it. (more) |

This post regarding scope is still open for community suggestions [Community feedback: What type of questions can I ask here?](https://software.codidact.com/posts/278648) Or we could start new ones.

Also, I still think the scope of this site is still too vague for anyone to moderate it. There's a lot of corner cases which the community has yet to come up with a consensus about: tool/software recommendations, asking "where to find documentation" questions, homework dump policy, "how is x designed...

What about the discussion about the "curate" privilege from meta [here](https://meta.codidact.com/posts/281579)? If it is something similar to "20k+" on SE rather than full moderator duties, then it might be easier to get volunteers. For example, I probably don't mind chewing through edit/close revie...

Generally, we shouldn't use the worst cases of cursing such as the F word because those collide with the "be nice" [code of conduct](https://software.codidact.com/policy/code-of-conduct).

You simply can't discuss proper program design in vague and abstract terms - that's nothing but a source of pointless & badly designed abstraction layers. _What_ is the data that's being passed around and _why_ does it need to be passed around? Does each node know the destination or is it the server ... (more) |

@dmckee Hmm yeah I just realized I'm not quite up to date with C++. I was thinking `auto_ptr` but forgot there's a better alternative nowadays. Anyway, plain old manual allocation would do the trick too. (more) |

A: Etiquette for posting comments Regarding "snark" - it is very hard and subjective to define. Our overall code of conduct says "be nice", but where do you draw the line. On SO, general gruff attitude tends to be treated very differently from moderator to moderator. That's obviously far from ideal. We would have to be smarter abo... (more) |

There's yet another aspect to keeping comments in private. A whole lot of users _don't_ want to be moderators. They don't want to teach random people on the Internet how to spell, how communicate with other humans, how to use the site and so on. They just want the crappy post gone from "their" site. ...

I get it every single time I do an edit now. It seems to be getting worse. Can we just disable this whole crap until it gets fixed? This is going to scale incredibly poorly when the sites grow. Then you'll have hundred posts like this per day. (more) |

Also related, what happened to the [Arbitration & Review Panel](https://meta.codidact.com/posts/277346)?

Related to this - in them early discussion stages of Codidact, I proposed that all feedback about bad questions should be given privately, rather than using the public comment field, since it is a well-known source of anger and drama. People are prone to respond bad to criticism in general, but espec... (more) |

@dmckee Smart pointers aren't necessarily smart in a multi-threaded context though. Because that makes heap allocated objects behave as if they have local scope. Not what you want - suppose you create a thread from another thread, then the creator finishes and goes out of scope. The smart pointer wil... (more) |

A: Write to same file from multiple threads Writing to the file on the HD is your massive bottleneck no matter how many threads you throw around. The limit is the physical memory access speed, not processing power. And since it is such a bottleneck, you should have a thread solely focusing on this job, similar to what @dmckee suggested. N...
