I assume CR = Code Review. Code Reviews are not a feature of git. It depends on which git repo hosting service/platform you are using (Github, Gitlab, Bitbucket, etc.). I think you will need to clarify which service/platform you are using. — Gino Mempin 19 secs ago
Q: C# Getting address with MemorySharp

SharkiI'm using MemorySharp to calculate the memory address from a pointer address and then inject values in memory. The code works perfectly, but I was wondering if this would be the right way. I found a little dirty the way I'm calculating the memory address. Maybe there's a easier way that I'm not a...

Yes Here CR is code Review. Consider there is a branch1 where I added my change and performed these in my terminal 1)git add 2) git commit -m"message" 3)cr the code review command generates cr link and I published that CR for review . But accidentally my branch1 got deleted my committed changes are in branch1. Now I need to send 2nd revision of my CR — Vasantham S 31 secs ago

To be honest @VenkateshDharavath there is nothing stopping two or more users who exclusively use pip to mess up the dependencies file the same way. User A uses venv. User B uses venv. User B added a bunch of lines that are not really dependencies to the project. User A remove them manually. So this isn't something that would be solved by removing conda from the workflow. It's also why code reviews and pull requests are essential — onlyphantom just now

Q: C++11 ThreadPool implementation

David TóthI made a simple ThreadPool implementation in C++ using only atomics ( neither std::mutex nor std::condition_variable were used). The idea is to have a threads_ready increasing to threads.size() until all threads are finished, and then back to 0 when all threads are ready to execute again. This wa...

Q: A file system watcher class for on-fly file reloading when it has been modified

eanmosI wrote a file sytem watcher class that is used to monitor file modification and then execute user-defined handler. Other file system events like moving or deleting don't need to be monitored. The usage is pretty straightforward: const auto watcher = fswatcher.on_modify("file.txt", [] () { ...

Across alien epics and procedural crime dramas, detectives and truth seekers have repeated the mantra: zoom and enhance. It’s passed into popular culture as a much-beloved meme, but in recent years, machine learning has increasingly made this fiction trope into an accessible reality. And we’ve got the demo to prove it.

@Peilonrayz IINM there is a "comment only" lock, but yes: Locking prevents all interactions
@Vogel612 yes there is such an option
@Vogel612 Whilst a comment only lock exists, the issue is the edits. "edit only lock"
Confusing terminology here: does "comment-only" lock (a) only prevent comments, or (b) lock question so users can only comment? I think it's (a), but wanted to check.
2:53 PM
A - "Comments only" - "Lock the comments on this post if the discussion is no longer contributing to its improvement. Users will still be able to interact with this post in all other ways."
Yeah, what I thought (and the one that's most usually useful)
other sites much more often have the problem of comments going in circles / devolving into a mess. It's a useful feature on the wider network, but feels relatively rare on CR
edit wars are much more interesting on CR, but the problem that edit wars create on CR is pretty much unique
Yeah, we're no TWP

3:09 PM
@pacmaninbw Thank you.
@Peilonrayz If they make a third edit, I'll suspend them for 3 days with a lengthy moderator message explaining what's going on. I think that drives home the point better than a temporary lock.
For now, it seems to be a minor nuisance that could be based on miscommunication.
It's hardly malicious yet.

@Peilonrayz Just wondering, did you look at the age of the question?
@pacmaninbw Yes, suggested a perminent, rather than temporary, lock because of the age

@Vogel612 I see you haven't changed your profile in a while. Would you mind getting it up-to-date?
good point
should be fixed (pending possibly caching)
3:58 PM
It is.
Thank you.
Chat-profile has been taken care of by a concerned third party.
I didn't even notice the change when I looked at it. That third party was faster than me in that context.
I hope y'all don't have too much of a mess on your hands with that.
I'm really itching to cancel some stars over there ... it doesn't feel right to leave them there.
ugh... finishing my second coffee, the lecture I'm watching and then I hope to have a clearer head.
I'll take a broom to it, don't worry.
There, a bit of clean-up. I may dump most of it in the Trash later.
I personally wouldn't, but I'm involved (and usually somewhat hands-off), so don't listen to me :)
4:12 PM
If this wouldn't have become such a mess, I probably wouldn't. I don't like erasing history.
But this made waves.
I'm going to kill the wave by removing the momentum.
for future reference: might've been easier to move the messages to the mod-only trash. That keeps the paper trail. I figured this made waves when four different off-site mods showed up
@Vogel612 They're removed and relocated, not redacted.
@Vogel612 What happened?
Someone made an IMO very tasteless comparison, I told them as much. An hour later an off-site mod showed up and things got blown out of proportion
I may have used colorful language to stress my position
in VBA Rubberducking, 1 min ago, by Mast
According to the Theory of Moderation, I should be leaving a comment as to why I stepped in here and did some rough clean-up. Suffice to say, some topics are a bit sensitive. There was a heated argument going on and the argument had to cease, one way or another. We usually tolerate a lot of off-topicness in the chat rooms and I won't get offended by profanity not aimed at other users (attacking others is still a no-no), but this got out of hand.
Nothing to see here.
4:36 PM
damn, this is the first time I miss my mod-powers, but it'd be only to find out whether there is a fight going on in the TL, so I obviously shouldn't have mod powers right now 😃
