2. 在JavaScritp中使用XML比较麻烦(还有浏览器的兼容问题),反而各种浏览器对JSON有非常好的支持。
(14)反序列化的使用总结
如果XML是由类型序列化得到那的，那么反序列化的调用代码是很简单的，反之，如果要面对一个没...

When is the thread pool used?
...e on the main execution thread. The only thing you can do is busy loop the CPU with in-memory computation, which will indeed starve the main execution thread and render your program unresponsive.
How does Node.js decide to use a thread pool thread vs the listener thread? Why can't I write event ...
Do asynchronous operations in ASP.NET MVC use a thread from ThreadPool on .NET 4
...ons (such as database and network calls to remote services). If you have a CPU intensive operation, asynchronous actions won't bring you much benefit.
So why can we gain benefit from I/O intensive operations? Because we could use I/O Completion Ports. IOCP are extremely powerful because you do not...
What is the strict aliasing rule?
...ut aliasing, it can omit those instructions, load buff[0] and buff[1] into CPU registers once before the loop is run, and speed up the body of the loop. Before strict aliasing was introduced, the compiler had to live in a state of paranoia that the contents of buff could change at anytime from anywh...
Fastest way to determine if an integer's square root is an integer
...that works ~35% faster than your 6bits+Carmack+sqrt code, at least with my CPU (x86) and programming language (C/C++). Your results may vary, especially because I don't know how the Java factor will play out.
My approach is threefold:
First, filter out obvious answers. This includes negative nu...

Why does this loop produce “warning: iteration 3u invokes undefined behavior” and output more than 4
...ause non-conforming programs to no
longer work as expected, such as SPEC CPU 2006 464.h264ref and
416.gamess. A new option, -fno-aggressive-loop-optimizations, was added to disable this aggressive analysis. In some loops that have
known constant number of iterations, but undefined behavior is ...

Alternatively you can use a heredoc:
