Q: Programmatically getting the GUID of an application

Jesse C. SlicerIntrigued by the events chronicled here (also here and here), I saw the inherent utility in having a program-specific GUID available. The SO answers that were correct seemed a bit tightly-coupled and verbose. So I set out to make my own for use. Looking for a critique on the idea itself as well a...

Q: I just finished a basic computer science program for class and wanted feedback on simplifications

TravelerThe program was to turn an integer into exact change and uses a bunch of if statements. Are there steps a simpleton like me can do to remove some or is it just how it will be?

@CaptainObvious Interesting one. Too bad I don't have time to answer it rn :(
@avazula Good, please wait till it's fixed. The current indentation is all over the place and I'm not going to fix it.
@Mast Yeah, I didn't want to do it either. Chances are it's part of the previous if loop but I wouldn't want to mess things in case they thought you could do an elif after a while

Generally, your question lacks a minimal reproducible example. However, how many bytes did you write? Is the reading or the writing the problem? As a new user here, please also take the tour and read How to Ask. I'd also suggest you submit the minimal example to codereview.stackexchange.com, there are a few bad habits. — Ulrich Eckhardt 46 secs ago

Q: looking for a web browser that doesn't use up a lot of memory when hundreds of tabs are open

RebroadI often have hundreds of tabs open in my web browser, but I'm looking for a web browser that can handle this in a more intelligent way such that it doesn't use up more memory than it needs for the currently visible tab, and ideally has some sort of hierarchy for the tabs based on when they were o...

@skiwi ^^
I would love such a browser as well. Currently I kill firefox daily and then restore the session :-(
I have a browser extension that just writes info for tabs I haven't used in a while to disk to save RAM
12:06 PM
As you predicted, register_printf_function() has been deprecated. However, a newer function has been added: register_printf_specifier(). It's usage is very similar to the old one. I wrote an example to register the %b specifier for printing unsigned integral types in binary, which you can see on CodeReview: codereview.stackexchange.com/q/219994/200418. — Cacahuete Frito 37 secs ago
@Vogel612 Does that fix the problem for you, or is it still unsatisfactory?
it's working well enough.
needed a bit to get a whitelist going that doesn't exclude every tab I open for work from getting pushed to disk
@Vogel612 What extension is this?
it's called "Tab Suspender", but I don't know whether it's available beyond Chrome
12:38 PM
Looks like it is (1) (2)
Firefox works perfectly with 2400 tabs open
They're not really open though, it needs to load tabs if I go to an older one
True. Still looking for a solution to save an instance.
Crashing it on purpose feels like the wrong solution.
1:28 PM
Maybe buying some more memory is an option :P
(6000 tabs seem to be the limit, for shy of 200 GB of memory. Not said if that's GiB or actual GB)
@MaartenBodewes Only 6000 tabs? Pffft.
That's 30 tabs a GB.
Firefox is going to beat that, hard.
Probably, the system quit at 6000 tabs because of other limitations though. And mind you, that processor they used? 64 core Epyc.
So actually their test failed. They should have tried something different to test the sponsored RAM.
1:45 PM
Is there a standardized test for the amount of tabs on a browser on a specific setup? See what my home set-up is going to achieve. Interested in what @skiwi system would maximally hold as well.

@Mast I'd rather not have it crash and lose all my tabs :D
I think my Firefox normally uses about 5 GB RAM but I've seen it use 10 GB sometimes too
2:26 PM
@skiwi I tend to stay under 200 tabs nowadays, so I haven't reached numbers close to that in a long while.
I recall 4 GB being a lot of tabs.

Oh no! Not the tab monster again!
Since I shut down my computer every night and shut down FireFox before I shut down my computer I never have more than about 12 tabs.
Of course I also run Edge with up to 10 tabs as well, so make that 22 tabs total.
Maybe a good question for Code Review. — Klaus D. 11 secs ago

@Duga rolled back - I almost ignored it because it was in code comments but the answer specifically mentioned that point
@SubliminalHash So because your question got downvoted and closed the only possible explanation is "pathetic" people seeking "status"? I think you're overthinking it and the reality is this is just a poor question — broad, lacking details, asking for "correct" usage when that's both debatable and left undefined, and possibly just posted on the wrong site (Software Engineering or Code Review might have been more accepting of this) — rather than people voting the way they did because...that somehow gains them "status" (however that was imagined to work). — BACON 15 secs ago
