Yes, that particular post should be marked as abusive and the code replaced by. if(a==b){ print("We have a problem, a is equal to b") } Assuming that indeed the code is dealing with a sit...
I host my website on a CentOS-Bash, PHP and MySQL environment; my local email client is engined by Roundcube. I don't know almost anything about PHP nuances. While my web domain registration is do...
I'm writing some functions in C that parses a part of a XML file (using libxml), but instead of extracting the content of the XML node that has a specific name, it outputs a string that's not in UT...
Are there practical reasons for designing/implementing a method(s)-only class/object? Follow-up background notes: This question is for languages that are not exclusively Object-Oriented, for exam...

I am working on a React Native app using Realm, Atlas Flexible Sync, and MongoDB, and I'm super confused about how subscriptions work. I'm coming from a .NET SQL background, so I'm completely new t...
Disclaimer: I don't work with EF therefore not an expert. EF is tricky and has a lot of dark magic inside so if you're not sure how it all works best to use good old plain SQL or simple libraries....

I am writing a todolist application in WPF with MVVM. I display the goals in a datagrid and the editing works fine. Changes made in the grid are saved to the DB when I click save. However, adding a...
