Q: Logger class (C++)

NovotnyI wrote a simple logger class for my project. Some key points: The interface is heavily inspired by Java's logging libraries (you can tell from the getters/setters that I'm a Java programmer). In particular I'm using printf style functions instead of std::ostream style, which I don't like very ...

That's about right, though you you need to think carefully about how you setup the dates for testing (e.g. set both to 00:00:00 on the first of the month, or set the URL date to 00:00:00 on the first of the following month and compare with Date.now(), etc.). I think this is more a code review question though, so perhaps off topic. — RobG 43 secs ago

A: HttpClient Wrapper for standardized API communication

@SimonForsberg Ok, just wondering.
 
Not sure why, but I noticed that the CommitStrip feed had disappeared in this room
 
Odd
 
Last time anyone changed the feeds was in November 2018: chat.stackexchange.com/…
 
3:12 PM
possibly got deleted because the oneboxing for feeds is basically broken for anything but XKCD
 
But last time a CommitStrip was posted was in August 2019: chat.stackexchange.com/…
@Vogel612 But the oneboxing has been broken for longer than August, hasn't it?
 
yea, definitely
maybe the paper trail is bork
 
Sometime after August 19th, it appears to just have... disappeared.
 
chat search is known to be wonky...
 
@Vogel612 You think anyone made a change to the feeds after August 19th?

@pacmaninbw FTR I don't understand your latest custom flag ...
you're not responsible for people bickering about naming in the comments on your answer
~sigh comment flags are weird to handle.
 
For The Record? I'm asking if you think I may have slowed down the comments trying to instruct a new user that they are wrong. Just decline it.
I happen to disagree with the domain specialists, but didn't feel that I needed to comment.
@Vogel612 ^^
And now I may have chased another user away from code review
@Vogel612 how much trouble do I get in for declined flags?
 
on comments: none at all, on posts: if you accrue declined flags at some point the system may ignore your flags IIRC
there used to be something called "Flag Weight", but that has been removed years ago
 
6:31 PM
@Vogel612 IIRC it'll just block you from flaggin at that point
 
yeah I think you get a flag ban if you have too many declines
Also the number of flags you get is based partly on your flag history.
 
On posts I'm at about 10% declined, but I think I've been improving.
 
10% probably won't hurt you
@pacman if you want a better answer on your meta, please provide details on what it should contain.
 
I never had any declined "Post" flags, but I do have one "Retracted (Self-Removed)".
