You are right, the on-topic page is confusing - trouble-shooting and general programming questions should obviously be on-topic! Perhaps we considered it so obvious that it fell between the lines ...
I find myself often writing code like this. try { // code } catch( FailedReadException const & ex) { file.close(); std::cerr << "Read failure " << ex.readFailure() <&...
The concept of field separator has some private cases in different operating system shells and their utilities (IFS on Bourne shell and derivates, RS on AWK and perhaps more) but I am having troubl...
As the comments in that thread mention, Captcha is a service, not mere software. The distinction is that Captcha are in an arms race with spammers, and must continually evolve to remain effective. ...
This can't be done with the standard library. It's quite common for people who want to do this to define their own extension method public static void Foreach<T>(this IEnumerable<T> it...
I have an array of struct: static struct basket baskets[MAX_ITEMLEN + 1]; struct basket { char *items; // malloc(itemlen * itemcount) int itemcount; }; char *items does all I nee...
The answer is "it depends". It depends on the language, how much buffering you're willing to allow, how much you're willing to accept some approximate/incorrect syntax highlighting, and whether you...
The auto feature was indeed mainly meant to solve long cumbersome template container declarations in C++. But when introduced to C23 - where there are no templates let alone template containers - i...
The answer by hkotsubo is correct. But just in case you're being very specific about fast-forwarding, it's worth stressing that you can use --ff-only as an option on the merge to abort if it requir...
C23 introduces the digit separator ' which can be placed anywhere inside an integer constant for the purpose of clarity and self-documenting code. These are otherwise ignored by the compiler when d...
Since this is all new, there might still be time to establish a consensus before this style feature too ends up "all over the place" (like upper/lower case hex, upper/lower case integer constant su...
Generally, I would say: On-topic How to install, configure, trouble-shoot and use tools specifically meant for software development. Compilers, debuggers, IDEs and so on. Asking questions rega...
I have two tables with millions of records. Every so often I need to join them and exclude just a handful of records where a bit(1) column is set to 1 instead of 0. I can do it with either, WHERE ...
I recently suggested an edit to an answer. Basically, I formatted some code, adding code fences around it: But at the "Review suggested edit" page, the differences are not clearly displayed. I...
The question is not "what will you do", but "what will we do?" This site is community-run. While of course there are a few rules that we need to impose to be able to host a community, for the most ...
I have a number of command line PHP scripts that are either run by a user or by Windows Task Scheduler. These scripts use DB and API credentials and I am wondering if there is a better way of stori...
I've kinda found a very limited, not so elegant, far from ideal "solution", using replaceAll: String regex = "(?:([aeiou]+)[0-9]+|([123]+)[a-z]+)\\W+"; System.out.println("ae123.".replaceAll(regex,...
Sometimes, either to reduce the amount of typing big table names or when joining a table to itself one will need to alias a table. Personally I find SQL statements with aliases harder to read and a...
I was inspired by the contests on Outdoors and Writing, and thought that having some challenges over here would be fun as well. What do you all think about adding a new category where people can po...
In Office 365 and Excel 2019 there is a TEXTJOIN: =TEXTJOIN(",",,A1:A10) which can be written into the cell where the output is required. Assumes A1:A10 has been populated to suit.
In Excel I would like to concatenate several strings into one. I could type and fill in the blanks CONCATENATE(A1, A2, ....) but it is a lot of work This would be cool, but it does not work CONCATE...
I found a confusing construction in several stored procs in an MS SQL 2008 R2 database: DATEADD(dd, 0, DATEDIFF(dd, 0, some_date)) As I understand it, these are the relevant function signatures: D...
Personally, I'd say that it depends on the question. Over on that other site, this ban was instituted to avoid opinion-based questions. For instance, suppose you asked: Is Angular a great framewor...
I have heard that it is undefined behaviour to make a pointer point outside boundaries of an array even without dereferencing it. Can that really be true? Consider this code: int main(void) { ...
Its possible to execute a MySQL file from the command line like so, mysql -u USER -pPASSWORD < FILENAME which triggers a warning, mysql: [Warning] Using a password on the command line int...
