It's possible to abstract IOCP and non-blocking sockets into a single interface with reasonable efficiency. For example: - To send data, user calls Socket::send(const char *data, size_t length). This starts sending the given data; the buffe

He probably doesn't have 64 threads, but he may have much more than 64 files or sockets. After all, the response was to the statement that "WaitForMultipleObjects as a kind of super-select to wait on anything". It clearly isn't, with this a

"It allows users to create a block level disk backups and restore it with ease" Nitpick: I distinctly remember Ghost having mentioned specific files while it was backing up or recovering, hence it's not (entirely) a block-level backup. Also

I do come in #reprap often (nick ambro718). For example, fan control could be made volumetric, based around how much filament is below the extrusion, not just the whole layer time. The bridge detection in Slic3r is a very restricted form

That seems like a waste. What's wrong with it?

Even if nobody manages to identify him (and probably nobody will), this says nothing about what a resourceful organization (such as an intelligence agency or a criminal organization) can do.

I've built the RepRapPro Mendel from a kit about 2 months ago. Don't have any "real" use for it - it's just a cool toy to have, considering it doesn't cost that much (paid 640 EUR for the kit). But it may come very useful if I try to buil

Right, but it's a trivial fix, in this case at least. I'm happy as long as standard code works in their compiler. Considering how much trouble MS are having with getting their compiler standard-conformant, I'd rather they work on the more i

Unless this breaks valid C++ code, I don't see how they need care too much about fixing it, especially since that would break existing code.

If they're really into reducing bugs, they should embed a complete proof system into the language, rather than try to guarantee something as simple as correct memory references - which isn't much of a problem to ensure for anyone serious ab

I think that this would be an instance of the bin packing problem, not the knapsack problem ( http://en.wikipedia.org/wiki/Bin_packing_problem ). (yes, the knapsack problem wikipedia page lists the bin packing problem as a generalization)

Hypothetical question: if all the knowledge in the world was available to you, how long would it take to build a modern electronic device from raw materials and without using any existing machine in the build process? I mean the actual time

You have to take into account that Microsoft can modify their own OS and implement what needs to be done in a proper way. On the other hand, third-party vendors can only use the public interfaces exposed by the OS, or resort to unreliable a

I think security bugs in Dalvik have less ramifications, because of at least 2 reasons: 1. Java code doesn't get executed by Dalvik automatically from web sites etc - an attacker has to get the user to install his application. 2. If an atta

The solution to these problems is for everyone to be completely ignorant of any character encoding and just deal with octets. If the characters represent UTF-8 text, then only when text needs to be presented or interpreted in some way, UTF-

No, of course not, I was just referring the the reluctance of the book to get modernized. I can't possibly imagine not using an abstract event loop.

Still not updated to mention anything more than select() as far as non-blocking IO is concerned, like poll, epoll, or, god no, using an abstract event loop. Nobody who cares about their code and sanity does blocking I/O with sockets. But th

I've tried this, and gcc indeed doesn't produce warnings even with -Wall -Wextra. Clang does however without needing any flags.

Because it's an implementation thing, it has no relevance from a theoretic view on the language. It's like the "compiled/interpreted" label.

C is also pure. After all, C code is just data until it gets compiled and executed. When and how often this happens is irrelevant. You could write a C interpreter in Haskell, and then your C code would be as pure as anything else in Haskell

SIGKILL is not really a "special case", because signals are not equivalent, they have assigned semantics. SIGSTOP also can't be caught. The fact that other signals can be caught and these can't just follows from their intended purpose. If t

I consider any uninterruptable sleep in the kernel a bug. There's no technical reason a process waiting for a resource (e.g. disk I/O) couldn't be killed on the spot, leaving the resource on its own. If it can't be, it just means it hasn't

Just for fun I made a benchmark for "two-star" and "one-star" versions of remove_if() and build() (to link an array of nodes). Code: http://ideone.com/D7bzmo Results with {gcc-4.7.2,clang-3.2} -march=corei7 -O3 build_onestar+remove_if
