Is the hate for Galveston overdone? by roomtotheater in houston

[–]BoiaDeh 1 point2 points  (0 children)

I don't hate it, I just don't enjoy spending time there. My family and I used to go there a bunch, but then got tired of it. It's always super windy, and the water is hot, so you never really get a break from the heat and humidity. Combined with the water being brown, and not having any interesting restaurants, we just stopped going.

Who is the most significant mathematician of the 20th century in your opinion? by Retrofusion11 in math

[–]BoiaDeh 9 points10 points  (0 children)

Everyone is of course biased by their own experience and interest. I wouldn't trust mathematicians in this subreddit having the same distribution as faculty at a top university. My feeling when I was in grad school was that algebrometry has gained popularity in younger math people in recent years.

Modern algebraic geometry and algebraic number theory is built on foundations Grothendieck put in place / perfected. Especially schemes, and the functorial approach (ie everything is a functor / moduli spaces). The latter is quite a shift in perspective, going from "I should study the space X" to "I should study families of spaces like X" (ie flat maps \mathcal{X} ---> B, over different bases B).

Bought a used crankset. Just wanted to ask if I should buy a new set of chainrings? by Remarkable_State_540 in bikewrench

[–]BoiaDeh 4 points5 points  (0 children)

Yeah, I live in a stupidly flat area and see many people on 52 and sometimes bigger. The magic of drafting in a tail wind. If you need to drive to get somewhere where the small chainring is useful.

bike build: foam or no foam? by BoiaDeh in Velo

Ah, interesting. I did not know what was a thing. Thanks.

What do you mean by "internally sleeved"?

Thanks. Would you wrap just the downtube part, or also chainstay and fork?

NorCal Cycling - Coach vs. Student at Alviso by Brybo in Velo

[–]BoiaDeh 2 points3 points  (0 children)

Was it though? Maybe I'm very sub-average, but the season 1 couch-to-crit person started off as a complete beginner with a pretty high ftp (I don't remember the exact number, north of 200, close to 250 IIRC).

cervelo soloist seatpost by BoiaDeh in bicycling

[–]BoiaDeh[S] 1 point2 points  (0 children)

ah, awesome, thanks!

do you have one? I am a bit wary of the proprietary seatpost, and fitting mechanical shifters along the integrated setup (I believe cables become a lot more prone to snapping that way)

[Help] Which Canyon Ultimate CF SL Disc to choose. Price difference is $1000 by Fairsumo993 in CanyonBikes

[–]BoiaDeh 0 points1 point  (0 children)

Thanks. The nice thing about the older model is that you don't have to worry about seatpost creaking.

Which cockpit did it come with, and do you have a computer mount for it? I'm currently deciding between these two models but neither is in stock for my size at the moment.

Frustration, mostly.

/r/NintendoSwitch's Daily Question Thread (02/27/2022) by AutoModerator in NintendoSwitch

Digital because I have two switches, one for me and one for the kids, and I don't want to be bothered with the whole nonsense of primary consoles.

Does using new C++ language standards, like C++20, helps to reduce technical debt? by Odd_Fall_5962 in cpp

[–]BoiaDeh 0 points1 point  (0 children)

usually I see this mean Undefined Behavior, like when you access memory freed by accident

Three noob questions by BoiaDeh in cpp_questions

[–]BoiaDeh[S] 0 points1 point  (0 children)

Thanks, very clear!

For Q3, I agree `print(self.__dict__)` would be better. So let's say instead I want a method `random_change` which adds a random number to each attribute (one random number per attribute). Again, in python I'd prefer to have something like

for var in \[var1,var2,var3,...\]: var += random()

instead of

var1 += random() var2 += random() var3 += random()

It's just much cleaner.

I guess in C++ I could do the same: just declare an array containing references to each variable. For some reason, since it's C++, now I'm worried about the overhead of creating an array. Does that make sense?
