最近半年大部分精力都在这个产品上，大家都很给力，阶段性的成果终于出来了。

In psychodynamics, the Id, Ego, and Super-Ego are the divisions of the psyche according to psychoanalyst Sigmund Freud's "structural theory."

表的演讲题目是：“对新奇无休止的迷恋——我们这个世纪的劫难”. 在演讲中，  
索尔仁尼琴抨击了本世纪以来俄罗斯乃至全世界文学艺术领域的以“迫不及待的喧  
闹为特征”、置身于“自编自演式的自我欺骗”中的种种“未来派”、“前卫主义”  
和“后现代派”. 他认为那些主义安身立命的基础是“对于新奇的无休无止的追求”

只要它不停地革新、革新、再革新的观念，它们所掩藏的，是一种不屈不挠并且由  

Northeastern Professor Gene Cooperman recently gave a curious Google engEdu tech talk, "Disk-Based Parallel Computation, Rubik's Cube, and Checkpointing".

Gene's starting point is that "disk is the new RAM" and the "disks of a cluster can serve as if they were RAM" because the bandwidth to 50 disks is 5G/second, same as the bandwidth

 一个内存池的实现实例

内部构造

内存池类MemoryPool的声明如下：

class MemoryPool{private: MemoryBlock* pBlock; USHORT nUnitSize; USHORT nInitSize; USHORT nGrowSize;public: MemoryPool( USHORT nUnitSize, USHORT nInitSize = 1024, USHORT nGrowSize = 256 ); ~MemoryPool(); void* Alloc(); void Free( void* p );};

MemoryBlock为内存池中附着在真正用来为内存请求分配内存的内存块头部的结构体，它描述了与之联系的内存块的使用信息：
