Is it standard for people in the Andes to take offence at people taking pictures of them? I don’t know, maybe it is, haven’t been there. It is not in Europe.
If you avoid the slightest possibility of unpleasant and pointless confrontations, then you’re going to lead a very dull life. I sometimes photograph random people. Never has anyone had an issue with that. Sometimes they approach me and we have a chat. That’s all that happens. I’ve had more chances of being hit by a car than anyone having an issue with me taking pictures of them. Boils down not being a dick about it.
It doesn’t matter which definition you pick. I e.g. had it defined axiomatically when I studied, i.e. we were given a list of properties which identify exp unambiguously and then we were given a proof of its existence. The fact that those properties were part of the definition doesn’t take away from their profoundness. The function could still just not exist. Same thing with defining by formulas. The map is not the territory.
Are they going to drop RStudio? I very much prefer its Qt interface over whatever VSCode invented. It’s fast, has nice keyboard shortcuts, none of that pointless padding and it just feels great to use.
The base graphics packages make the plots as ugly as the ones generated by gnuplot though. ggplot2 on the other hand has very pretty output. And the concept of grammar of plots just makes so much sense to me.
This can’t be answered in general. Flamegraphs are measurements of what happened. But just like a ruler doesn’t tell you whether a given human is atypically short or tall for its species, a flamegraph can’t tell you which portion of the program takes too long a time. You need to have prior knowledge about data structures, algorithms, memory bandwidth etc in order to confront your justified expectations with the reality and be surprised with something. And it will all depend on the particular program you profile.
This has nothing to do with GCC being a first-class citizen in Linux. It’s a kernel feature. The kernel doesn’t care which compiler or debugger you’re using. You can dump core of any process regardless of the language it’s written in. Every modern OS supports that.
And even if you do know what it does, it’s very impractical given that it’s a global option. Turning it on for selected portions of code would be a completely different game.
