And its weakness is that those ways in which you can , you're practically required to use to accomplish anything interesting. You can't even perform formatted output without throwing the entire type system out the window.

There's a big difference between Lenovo selling bloatware rights to an adware company and the NSA (or whoever) bugging some hard drives. Is that spyware Windows-specific?

In a company as big as Lenovo, I'd be kind of surprised if the person or persons who decide what bloatware to load onto the consumer image make any sort of hardware decisions. There's also that this particular kind of compromise i

The solution is actually pretty straightforward: don't do everything with text. The actual content you want to manipulate, sure, do that with text. But there's no good reason to structure with syntax except that that solution is

The STL is a product developed and maintained by SGI. If you look at the containers listed in the article and on the SGI page, you will see a different set than is present in the C++ standard library, especially if you discount the containe

Nitpick: the STL is not standard C++. The containers in the standard library are listed at http://en.cppreference.com/w/cpp/container .

Have you ever personally tried to optimize a Lisp program? It isn't terribly difficult, as optimizing goes. You have full access to control flow as far down as goto, and you can use machine integers and arrays. Depending on the impleme

I have maintained C++ code that was poorly written, if that's what you're getting at, but I have yet to find myself maintaining C++ code that has been poorly written as a result of the design of the language.

Was that through technical failing, or was the project just mismanaged into the ground like the Alpha? Or was it killed by AMD's backward-compatible 64-bit architecture?

No AMD stuff. We just had a box with a couple of Xeons, a Xeon Phi, and a K20.

You are correct; and of course, any hardware-level behaviour is likely to be implementation defined. I should note that MSVC [1] guarantees "non-deterministic and cryptographically secure" behaviour; and that libc++ [2] uses the &
