I have written a class which takes all the TypeORM entities, create a connection and export them. Please let ...

(Not ideal to corrupt it but the toothlessness of unused annotation seems to have been continued even in standard C++ annotations, which puzzlingly went with "maybe_unused" on the parameter definition, instead of letting you mark points in the control flow after which you don't want a variable used and have the compiler catch it.)HostileFork 54 secs ago

Not sure if I've said this to you before, but products is a bad model name. Class names for Models in Laravel are StudlyCase and singular, so Product. Anyway, you can set validation rules 'minprice' => 'nullable', then handle if($request->input("minprice", null) && !$request->input("maxprice", null), etc etc. But, code reviews/suggestions for better approaches aren't what Stackoverflow is for. Maybe try codereview.stackexchange.com for that. — Tim Lewis 47 secs ago

@pacmaninbw With SE staff making one bad decision after another, and the community being helpless in stopping them, it just stopped being fun anymore. The licensing issue was, for me, the last straw. They didn't have to do it, and, as far as I can tell, they stand to gain nothing from changing the license. We've told them that it's a violation of trust, and yet they seem to think that they can just make the problem go away by ignoring it.
That basically sums up their attitude these days. Ignore everyone.
What could have been the motive for the license change in the first place? A test to see what they can get away with?

Using SE is probably unavoidable for Q&A that is essential for work, but Code Review was mainly for my own fun and education, and once the fun is gone, what's the point?
To give them content that they can relicense at will, to sell more sleazy ads?
@200_success I can't even try to be contrarian to that because 70% of my justification for changing jobs right now is that it's no longer enjoyable.
Sorry, gotta go to a meeting starting in a few minutes.
And my entire reason for not participating in SE is that it's not fun anymore.

You can create several tables in a single SQL statement by putting them all in a create schema statement. I have spent a couple of decades working with Oracle at a number of different companies and have not once encountered a situation where anyone has used a create schema. I'd wager that the vast majority of Oracle developers have no idea that such a statement exists which would create issues for things like code reviews/ script generation/ etc. Plus it makes life much harder when you have errors in one of your scripts that need to be debugged. — Justin Cave 28 secs ago

You should give more details with what the error is and where it happens and what you've done to try and fix it, including the code of any attempts and then maybe someone will point you in a better direction, rather than giving your whole code and saying 'it doesn't work'.

@410_Gone ugh, it should be fun....I'm sorry to hear you both say that(@200_success) makes me a sad panda.
@MathieuGuindon On this question, I believe the poster is indicating the input loop terminates when the value zero is input. For C and C++ if (n) is equivalent to if (n != 0). What makes the code wrong is the && (media += n, ++c). codereview.stackexchange.com/questions/232755/…
I've had to do a lot of things in my life that weren't fun. Trying to keep CR clean is quite relaxing relative to those moments.
@MaxB there is enough information in this response for it to satisfy your Q, though I acknowledge that it does not solve your desired output to perfection. Do keep in mind that SO is not a code review or homework guide site. Be mindful of the work you're asking of people – and the work they've provided. — Yaakov Bressler 25 secs ago

Q: Used WD-40 on headset and now it loosens daily

Eran BetzalelI've used WD-40 on my bike's headset as it produced some cracking noises. The result is a headset that gets loose after every ride. I've tried to use a wrench to tighten it, alas, it went loose after a couple of days. Any recommendation of how I can fix my mistake? UPDATE - image of the bike

Use WD40. Everything comes loose. And you wonder why.
Naturally, the proposed solution is duct tape.
