mind, the essence is human. A different angle. From artificial intelligence, the computer is stored in the human learning and design indirectly reflect people's learning and reasoning, stored in the computer method. Learning and reasoning can be carried out first in the human mind, again put into the computer stored in the process, but also in the computer according to the design of people in the introduction of new storage. The nature of reasoning, learning and storage requires human thought t

As for Row 3, the same is true because the OO in goooogle may be prior to O, for example, go (ooo) oogle. Therefore, this line also meets the requirements.
Consecutive character classes: If I do not want to have lower-case bytes before Oo, I can write [^ ABCD .... z] Oo, but it does not seem very convenient. Since the ASCII encoding sequence of lower-case bytes is continuous, we can simplify it to the following:

Solve the problem of overlapping OpenOffice menu fonts. Another method is Linux general technology-Linux technology and application information. The following is a detailed description. After being transferred to Linux, I opened my beloved OpenOffice (OOo) and set it as a Chinese interface. After restarting the program, I found that the menu fonts overlapped and the interface was terrible. After searching, it means that it is okay to install openoffic
constantly, this leads to a large number of OOO data packets (this is because the cpu id changes, resulting in the following soft interruptions constantly switch to different CPUs, this will lead to a large number of unordered packets ).
How does RFS solve this problem? It has two tables rps_sock_flow_table and rps_dev_flow_table. The first rps_sock_flow_table is a global hash table, which is for socket, ing the CPU corresponding to the socket, here
Originally, when I wrote Ajax in vs2003, I referenced Ajax. dll. Today I used vs2005 to find that this Ajax cannot be used. In the previous call dialog box, "jscript runtime error: the object is missing", so I found an ajaxpro.2.dll to reference it. All right, this problem is solved. But I don't know what other friends can do.
