Efficient Algorithm for Bit Reversal (from MSB->LSB to LSB->MSB) in C
...ttention since it deals with a simple problem that requires a lot of work (CPU cycles) even for a modern CPU. And one day I also stood there with the same ¤#%"#" problem. I had to flip millions of bytes. However I know all my target systems are modern Intel-based so let's start optimizing to the ex...
What's the point of having pointers in Go?
...reeNode {
value int
left *TreeNode
right *TreeNode
}
Java, Python etc doesn't have this problem because it does not allow you to embed composite types, so there is no need to syntactically differentiate between embedding and pointing.
Issues with Swift/C# structs solved with Go pointers

How slow are .NET exceptions?
..."in real life there'd be more stack to go through, so you'd blow the cache etc" - but using error codes to work your way up the stack would also blow the cache, so I don't see that as a particularly good argument.
Just to make it clear - I don't support using exceptions where they're not logical. F...
Performant Entity Serialization: BSON vs MessagePack (vs JSON)
...ere such keys are "longer but repeated alot" (MsgPack, JSON/BSON, and XML, etc over many records) but won't help ProtocolBuffers at all here.. Avro does key redundancy elimination manually by transmitting the schema separately.

5．下面介绍一种比较复杂的情况，利于对问题的深入理解。例如我们现在用到的ICF底层库就有很多类似下面的函数：
void CTestDlg::GetString(BSTR* state)
{
_bstr_t m_state(L"cc");
*state = m_state.copy();
}
其中_bstr_...

What is the Haskell response to Node.js?
...sometimes, though). This makes it easier to avoid locks. However, too much CPU processing in a callback will impact other connections (in this case, the task should split into smaller sub-tasks and re-scheduled).
You have no such problems, ghc will distribute your work amongst real OS threads.

How does libuv compare to Boost/ASIO?
..., synchronous and asynchronous file system operations, process management, etc. In contrast, Boost.Asio's original networking focus surfaces, as it provides a richer set of network related capabilities, such as ICMP, SSL, synchronous blocking and non-blocking operations, and higher-level operations...
Are non-synchronised static methods thread safe if they don't modify static class variables?
... share data between threads - you must take care of atomicity, visibility, etc.
This method only operates on parameters, which reside on stack and references to immutable objects on heap. Stack is inherently local to the thread, so no sharing of data occurs, ever.
Immutable objects (String in this...

加上__attribute__((noreturn))则可以很好的处理类似这种问题。把

extern void myexit() __attribute__((noreturn));之后，编译不会再出现警告信息。
