I. AOP framework
EnCase
C # is written and developed for. NET platform provides an AOP framework. EnCase
Uniquely provides the way to deploy aspects (aspects) to Run-time code, while other AOP frameworks rely on configuration files. This approach to deployment (aspects) helps inexperienced developers improve their development efficiency.
Nkalore is a programming language that expands C # to allow in. NET platform uses AOP. Nkalore's syntax is simple and intuitive, and its compiler is based o

At present, still in the company vigil, idle nothing to try the algorithm problem.Quick hand hi

, external SCM can communicate with USB device by CH375 according to the corresponding USB protocol. CH375 also has built-in firmware to deal with the special communication protocol for Mass-storage mass storage devices, and the external SCM can read and write commonly used USB storage devices (including USB hard disk/USB flash disk/u disk) directly in the sector as the basic unit.
The following is the mode diagram of CH375 and SCM connection:
In the practical application, the CH375 chip and th

of CLH queue locks is that the space complexity is low (if there are N threads, l a lock, each thread gets only one lock at a time, then the required storage space is O (l+n), n threads have n mynode,l locks have L tail), a variant of CLH is applied in the Java Concurrency Framework. The only drawback is poor performance under NUMA system architecture, under this system structure, each thread has its own memory, if the memory position of the forward node is far away, the performance of the lock
internal registers in the P2 beats. (Note the phase relationship of P1 and P2)A machine cycle consists of 6 states, and if the execution of one instruction is divided into several basic operations, the time required to complete a basic operation is called the machine cycle. Single-chip microcomputer single-cycle instruction execution time is a machine cycle.The instruction cycle is the entire time required to execute an instruction. The instruction cycle of

We ask this editing distance of two strings, which is the minimum number of operations to turn a string into another string. Input for

If Mono succeeds, then not only does "build once, deploy anywhere" become a reality and a huge business significance, but it will also be a big push for the Linux,unix platform application industry.
The most important operating environment for the current mono has been initially implemented, which means that Ms's CLI will be decoded by the interpreter on the Linux system and t
