Ok, but you get my point: there may be actual limits to the development of space travel technology. Your logic seemed to imply there was none. Sorry for speculating though.

I see an important difference. Planes, boats and cars are technology. Before we had planes, there were scientific evidences that objects heavier than air could fly (= birds). This in fact was a strong motivation for people to develop the te

Ok, let me rephrase then: On modern systems, checking the return value of malloc() is not a proper way to check that the system is out of memory and therefore it doesn't guarantee that the program will run correctly in any case. That&

Note that on many systems (e.g. Linux), malloc/calloc won't always return NULL when you're out of memory because of lazy memory allocation policies. It will only crash when you start reading / writing. That makes it argu

It's definitely a good idea. Pipes are both very powerful and very simple to use and debug, yet they are not very common in general purpose programming languages (examples?). I'm not surprised that someone is trying to build a lan

As soon as price enters the equation, you're not going to maximize your life expectancy. This is math. > I think that anyone would agree, though, that either outcome is far better than dying young. Right, but how can you be sure?

C isn't a subset of C++ (eg see [1]) but more importantly proper C++ has very little to do with C. In my experience people use "C/C++" to refer to "C with class compiled with a C++ compiler" rather than to &quo

It's a nice quote but with this logic you can justify any absurd attempt to do anything. At the time Columbus crossed the Atlantic Ocean it was a (relatively) reasonable thing to do given the boat they had. Can we say the same about t

A good definition from the PDF: He wanted, in fact, to show that it is possible to convince without revealing, and so without unveiling his secret. Or from wikipedia [1]: In cryptography, a zero-knowledge proof or zero-knowledge protocol

With traditional manufacturing methods, you would need to make a mold. Molds are very expensive unless you can reuse them for thousands of units.

This is an instance of finding the Pareto front [1] of a set of points in a two dimensional space. This problem is also known as " skyline queries "! According to [2], author's bound O(n log(n)) is the best bound for d=2. [1]

Ok so to summarize: when they are talking to higher-ups, people don't want to make strong claims so they use wordings that make it explicit that this is "only" their personal opinion rather than an absolute truth. And they ty

In reply to sibling posts. - if you need dynamic storage you should use a std::vector instead of new []. - with std::vector-s, if you want to save the cost of the copy you can redefine the vector allocator to use realloc or even mremap. Edi

It's the same with realloc: there is no guarantee that it will grow the chunk in place.

If you need to realloc a fixed size array, souldn't you use a std::vector instead?

I really like in-shell floating point operations. But this: > / 1 0 +Inf Is not the correct answer - even as a limit - since the limit of 1 / x (when x -> 0) can be +Inf or -Inf.
