Quickly create large file on a Windows system
...me less than 1 minute to generate a 1 GB file on a quad core 3.0 GHz Intel cpu. With the fsutil.exe tool as posted above, it only takes a fraction of a second to create it. So it's true, that tool creates sparse files. It's even bigger, it's 73,5 KB. This one is better for generating large files for...

Why extend the Android Application class?
... limited? just passing the data objects instead of serializing them saves cpu and memory. parceling stuff for inside-process-on-same-device handovers is not ideal in any way. I really don't see the point of intentservice use like that(just do the other thread with new). really a lot of the stuff t...
How do I use IValidatableObject?
...he results - this is beneficial if some of the validation checks are IO or CPU intensive.

Why is 1/1/1970 the “epoch time”?
...ter with 9KB of RAM which used transistors and diodes for logic gates as a CPU (no chips at the time!). So it wasn't "silly" to make the most basic thing that worked.

Advantages to Using Private Static Methods
...
Passing an extra parameter means the CPU has to do extra work to place that parameter in a register, and push it onto the stack if the instance method calls out to another method.

Calculate the execution time of a method
...e reason for this is that the Stopwatch in .NET does not take into account CPU affinity, and therefore, if your thread moves from one core to another, the StopWatch doesn't take into account the execution time across the other cores; only the one where the thread began execution. What is your opinio...
SQL Server IN vs. EXISTS Performance
...r amount of rows on each table (by fair I mean something that exceeds your CPU processing and/or ram thresholds for caching).
So the ANSWER is it DEPENDS. You can write a complex query inside IN or EXISTS, but as a rule of thumb, you should try to use IN with a limited set of distinct values and E...
What's the best way to break from nested loops in JavaScript?
...imple answer. This should be considered as answer, as it doesnt strain the CPU intensive loops(which is a problem with using functions) or it doesn't use labels, which usually are not readable or shouldn't be used as some say. :)

...，做了delete ip操作，所以释放了内存，不会有内存泄露的问题。
接下来的操作很自然，无需多言：
ptr = rhs.ptr; // 复制U_Ptr指针
val = rhs.val; // 复制int成员
return *this;
做完赋值操作后，那么就成为如下图所示了。红色标注...
