On iOS, malloc (1ull 35) will succeed. It will reserve 32 GB in the address space but nothing else.
Well, at least some page table entries were created. Free memory block list in heap was extended as well (though this could be avoided if only brk or mmap were used). The operation has some overhead but it is very little if the allocated memory is never used.
BTW i still don't understand what's with all the rust hate?
This is from programmers who know C or C++ and are lazy to learn something new. They bash Rust since it is the most viable safe option for domains where C/C++ is used. Part of the "hate" is also that Rust has ownership type system. It is more restrictive than "normal" type system v C/C++. It is harder to use especially if you do not have prior experience with "limiting" languages like e.g. Haskell or Clean.
My dreams are kind of boring. I get the ones I remember rarely, maybe once a month. The first dreams I remember were already dreams where I knew I'm dreaming and I could control them to some level. But the more control I extorted the sooner they ended. The one in which I managed to fly (for a few seconds in subjective time) was fun. It was and is quite easy to find out I'm dreaming. Reality does not work well while dreaming. E.g. clocks not moving, impossibility to investigate more and more into detail, law of physics not obeyed,
I do not remember any scary dream. But my mom told me that I had one when I was a kid. She made a macrame depicting a specter for me and put it in my bedroom. The macrame specter was supposed to protect me. I guess it worked either by banishing the bad dreams or by making me forgetful enough that I did not remember any
... the reality is that you can write very safe C/C++ code if you want to.
This is such a crappy argument! To illustrate I'll give you an analogy: You can walk very safely on stairs without handrails if you want to.
Despite that building codes generally require handrails for stairs.
:) To be honest I think that more than 2 wheel recumbents suck. E.g. trikes are not good for healthy people who can maintain balance; trikes are too clumsy. But something like a two-wheel "high racer" with short wheel base are fine for normal city use. Occasional curbs up to about 6 inches are not a problem. One can just ride on a small curb slowly in approximately perpendicular direction without an issue. I use my recumbent for any errands which are over paved roads, do not need a car trunk and are not longer than 34 miles.
Recumbents are a complete crap outside of paved roads. You cannot do a bunny hop on them which more or less prohibits their use for "cross country", "trail", "enduro",
I'd write the rules to say that the bicycle has to meet certain requirements for mass and volume, but beyond that anything is fair game.
It would transom cycling into a competition of small motorcycles. The limit should be: It must be only human powered and any stored energy in the bicycle should be zero joules at the start of the competition.
... and driving the technology forward is an important part of most bike racing.
If that would be the goal then there would not be any technological limits except that it must be human powered and some basic safety limits (like it must have working brakes,
No, bicycle races are not about technology. It is about marketing UCI approved bicycles to the masses
French Energy Minister Agnes Pannier-Runacher countered that large-scale air conditioning would heat streets with exhaust, worsening heat waves.
"HEAT FLOW DOES NOT WORK THAT WAY!"
(For anyone who's unclear: all the heat that you're pumping out of houses is basically perfectly offbalanced by the heat penetrating into them.
It does work that way. Even if the AC would have infinite efficiency (instead of typical values of 2-3), you are increasing temperature out-of-the-house by reducing temperature in-house. But I agree in general that most of the time it will not matter and Agnes is wrong in practice. The reason being that the heat capacity of all the in-house areas is too small compared to heat capacity of all the outside areas. Therefore outside temperature increase will be negligible almost always. Maybe something will be measurable in narrow streets where air flow is low and which are full of AC radiators from the apartments around.
