...ependencyWalker. It told me that the not all the dependencies had the same CPU type (x86/x64). I copied all the files that had the same CPU type to my application's bin folder, and that resolved the problem.

问题的提出申请过那么多的微博，数申请网易微博的动机最不纯，因为它的字数限制不是传说中的140字，而是163个字。当年觉得很可爱，于是就注册了，之后再也没登录过。今天在人人网转发状态，提示我超过140字了，突然就好...

Why do stacks typically grow downwards?
...n (because I didn't design them). My thoughts on the matter are that early CPUs got their original program counter set to 0 and it was a natural desire to start the stack at the other end and grow downwards, since their code naturally grows upward.
As an aside, note that this setting of the prog...

This should be accurate, but it is a CPU intensive way to go about it. Normally you want an interupt driven implementation so that the process does not consume CPU cycles while it waits. This shouldn't be a problem for infrequent short waits, as is probably the ...

MapReduce模型有什么问题？
第一：需要写很多底层的代码不够高效，第二：所有的事情必须要转化成两个操作Map/Reduce，这本身就很奇怪，也不能解决所有的情况。

Why is Go so slow (compared to Java)?
... Generally, real world systems are constrained by IO not by CPU. Therefore, whether Go is 2x or 5x is slower hardly makes as much as a difference to capacity planning as failover, load balancing, caching, database topology and the like. This is why apps at the scale of YouTube can af...
Floating point vs integer calculations on modern hardware
...all of the data can reside in cache, where they can be quickly sent to the CPU. A very, very slow floating point operation that already has the data in cache will be many times faster than an integer operation where an integer needs to be copied from system memory.
I assume that you are asking thi...
Should I always use a parallel stream when possible?
...elves may be processed simultaneously. In other words, if you have several CPU cores available, each part can run on its own core independently of the other parts, while processing its own elements sequentially. (NOTE: I don't know, if this is how parallel Java streams work, I'm just trying to clari...
