Not only pricing out… but where I am credit rating requirements have gotten absurd.
A 3 bedroom 1200 sqft house generally wants $6000 a month + $9000 security deposit + 750+ credit rating to move in (as well as 3x rent income)
It’s virtually impossible to rent a place

Even the newest c++ is as performant as C (or more in some cases because of optimizers)
People dislike c++ because its very complex, it’s easy to write bloat, and a lot of the language is designed around OOP anti-patterns (imo)
Because of that, c++ codebases have gotten sloppy

You can rent a $2-3m house for about $5000-8000 a month here in the Bay Area, mortgages and taxes are way worse than rent at the moment.

Exceptions and the size of libstdc++ are the main reason I would say C.
There’s also ensuring you’re following a widely supported C spec.

It only works if you control the lighting of your play area, and have a color accurate display.
Any rooms with windows and you’re pretty much out of luck. A bad display and you’re out of luck.

C is generally how I teach people systems programming from zero.
I start with a primer on what the cli is, what a compiler/linker are, environment vars, look up docs and move on to “hello world” after that.
It means a week or two of lectures before coding, but it’s worth it.

You can get that amount of storage and memory, you won’t get that amount of compute + battery life, and surely not at the same time.

Yeah, imo he’s right.
Reading more of his replies, his solution is tailored to the limits of their hardware, not the wording of the problem.
So it’s not lossless as so far as the signals they gave, but the whole intended signal is preserved.

It’s really bad. Most big corps have two SDE routes:

Big tech is strange like that. The average game dev can absolutely lap the average faang dev.
I do think on the high end though, the big tech companies have the *truly* top tier players.
Working in core windows, FRL, MSR you’re surrounded by astounding talent.
Half-Life got open sourced. I am going to read this code when my thesis is done.
Game dev is hard. When I went from working small game dev studios to big, glamorous tech corpos, I was amazed at how comparatively incompetent the big techies were.

“No, it’s fine, I’m just debugging”

From a c++ dev who fully dove into rust:

Every time I bring this up people say it’s a skill issue, but like… I don’t want to have 15 files open to see what some code does because everything is “perfectly encapsulated”.
Even if Object Oriented Programming wasn't slow (it is), reading a OOP-heavy code base sucks because the logic is broken into little pieces and spread all over. Makes it hard to understand the system as a whole.
