| Question | — |
Is MISRA-C useful outside safety-critical and embedded programming? When discussing best or safest C programming practices with various C gurus on the Internet, the "MISRA-C guidelines for the use of C language in critical systems" often pops up as a source. This standard was invented by the automotive industry and is pretty much mandatory in all automotive firmw... (more) |

A: Do we really need the [tools] tag? No, it's not helpful, it's far too broad and doesn't make sense to use in combination with any other tag either. It can't be used for searching or categorizing questions either. (more) |

Is STL a thing in C++ still though? Has it not been swallowed up by the "standard library" just like everything else? Why do we need a tag for it to begin with? (more) |

I wonder what's the rationale behind any of it. What if I have a question about the MySQL dbms specifically, which is not related to SQL language at all? Does this mean that the site will force me to add the extra unrelated SQL tag? (more) |

@laserkittens Those are borderline on-topic. An excel formula is (arguably) a very limited form of programming. If you think they should be off-topic, you could propose it [here](https://software.codidact.com/questions/278648). However, it has been suggested to either migrate them to either a "Power ...

Besides, lets say you drop templates and overload int + float functions only. You will most likely need to write the implementation of those functions differently, because these types are compared & promoted differently. (more) |

@dmckee DRY is probably the most overrated and dangerous design principle out there, though. Often it causes more problems than it solves, due to overly complex and obscure code. Maintaining a template metaprogramming hell will almost certainly cause more bugs than maintaining 2 functions with code r... (more) |

Yet another option is to [KISS](https://en.wikipedia.org/wiki/KISS_principle) and not use templates at all, but to provide & overload functions for the supported types only. Because restricting the type-generic interface to only support certain types kind of goes against common sense. (more) |

A: Growing software.codidact We can't go and shamelessly promote Codidact in SO comments etc just for the sake of it - that's regarded as spamming and might get you banned, plus it will give Codidact a nasty rep. Similarly, SE and many other sites frown upon using "signatures" in your posts. What you can do - and what I've be... (more) |

"Aviation safety is built, pretty much completely, on that kind of "anecdotal evidence"" Well, not really. Rather a group of experts getting together and agreeing on how things should be done. If you can quote for example DO-178, then that's a well-respected standard and canonical source. (more) |

Questions about the _use_ of software for other purposes than programming is clearly off-topic. Whether we have somewhere to direct such questions or not doesn't matter. This is not about scripting but about how to use a command line zip program. (more) |

If you enforce a style that always uses braces you can check it with static analysis tools though. Unlike using the wrong variable and similar application level bugs. (more) |

But in the end experienced C programmers have already been through missing semicolon, missing brace hell. It's an initiation rite that everyone learning C must go through. After you have coded for some 5+ years you can spot and fix these kind of bugs even if you wake up in the middle of the night wit... (more) |

A: Is omitting braces for single statements bad practice? Not using braces is considered bad practice by widely recognized industry coding standards (MISRA-C:2012 rule, 15.6, CERT C EXP19-C and others). Once upon a time I liked to skip out braces too, but every C (or other language) programmer using that style will ultimately write missing brace/indentio... (more) |

A: Counting number of assignments that a `fscanf` format strings implies Consider using look-up tables to increase execution speed (at the cost of some 200 bytes .rodata use). For example this: static const char specifiers[] = "diouxaefgcspAEFGX"; could be replaced with static const bool specifiers[UCHARMAX] = { ['d'] = true, ['i'] = true, ... (more) |

The size of the code format window is much too small. When posting a lot of code on the site, the "code format window" is much too small: 1 I'm talking about this thing 2 3 4 5 6 7 8 9 10 11 12 13 14 15 The scroll bar appears after only 13 lines for me, so I can only view ... (more) |

@Peter Taylor Combining several tags to form a meaning rarely ends well. I think making one tag per program will work better in the long run. (more) |

Command line is not programming. Everyone else but conservative programmers have stopped using command line, but that doesn't make it programming still. Once upon a time, regular users used command line, in the days of UNIX and DOS. (more) |

Anyway, I think such recommendation lists may work out well if they are extensively curated and there are rules for them. I tried to make a push for quality [here](https://meta.stackoverflow.com/a/379637/584518) but nobody was interested in that. From what I hear the C++ book list is of decent qualit... (more) |

The C book list on SO is _not_ canonical, it's a complete fiasco and a perfect example of how horribly wrong community-maintained resource collections can go when they aren't actually maintained. Note the "Warning!" disclaimer on top of the post and the meta discussion. (more) |

Physical vs virtual memory has nothing to do with the subject. From a general computer perspective, memory segments either reside in RAM or ROM, where RAM is a sloppy but industry standard term for "read/write memory". (more) |

Regarding stack & heap specifically, that was a good call. There is the data type stack and there is heapsort. Dynamic memory allocation and heapsort in particular have nothing to do with each other. (more) |

A: What is our policy on tags? Luckily, we are in a position where we don't have to re-invent the wheel. We can see what went either wrong or horribly wrong at SO, then avoid making the same mistakes. Some common problems: - Making too generic or ambiguous tags that could mean a lot of different things. - Allowing crap tags th... (more) |

A: Are reference requests welcome here? If we ignore the part of recommendation questions leading to opinion-based answers, the main concern against these kind of questions is that they don't add anything of value to this site. But also one of the main design concerns of SO: they didn't want to end up as yet another low quality programm... (more) |

Way too vaguely phrased in my opinion. We could however say something about copy/paste homework dumps. I've been meaning to suggest that such dumps should always lead to user suspension since they are rude, but that's for another post. (more) |

Also if we can't narrow the scope enough, I don't think the site will attract enough experts - they tend to shy away from "everything about software & stuff" sites were random hobbyist trade bad advise with each other. We already have some 100 sites like that on the Internet. (more) |

This isn't about first time visitors as much as defining what the site is actually about & provide guidance to moderators.
