Here's something to ponder on: What are the proper semantics for copying a thread? What is it you want to express by doing that? You'll find that usually the copy constructor has been deleted only for those classes where the sem

Comment on my mentioning on move semantics, because I feel that this really ought to be pointed out: In all the C++ standard library implementations of std::thread the only member variable of that class is the native handle to the system th

It could also be a tagged value. These are quite common in code created by "high reliability" languages (Ada, OCaml). The high bits are used to carry some metadata. E.g. you might want to set a certain bit if the value went outsid

Simple speculation: The software makes heavy use of 80286 protected mode and its quirks, which in an embedded hi-rel environment is fine. An areospace 80386 doesn't necessarily have higher throughput (remember, these are in-order-execu

Byte ordering issues are easily addressed by still emitting text, but not converting to a base that differs in a prime factor. Just emit the mantissa and exponent in – say – hexadecimal form and the negative sign bit as a `-`. It avoids all

What is it with all those reduced font/background contrast styles? To me these are terribly hard to read. As a matter of fact a large part of my Stylish/Greasemonkey sets are just there to get back decent contrast on text.
