The Oracle tutorial you are looking at is: three questions for Oracle Index.

Although there is a lot of data on the use of indexing, DBAs and Developer often deal with it, but the author found that there are still a lot of people misunderstand it, so for the use of common problems, say three

Study Questions 15-1 Note that this problem is said to have a direction-free graph, so there is a dynamic programming algorithm to calculate the longest weighted simple path.Set Dis[u] Dis[u] represents the longest weighted simple path from u u to t T, you can get the following equation:Dis[u]={0max (u,v) ∈e{w (u,v) +dis[v]}if u=totherwise dis[u]= \begin{cases} 0 \text{if u=t}\\ \max \limits_{(u,v) \in E }\{w (u,v) +dis[v]\} \text{otherwise} \end{ca

As a seoer, we are inevitably confronted with a wide variety of users when it comes to different kinds of optimizations, and it does take a lot of skill to communicate with these people. If you do not talk, you will lose the user, or the price is depressed, no profits. As the saying goes, "Our client is God."

A few days ago, on Sina Weibo, I had two study questions about TCP, which sparked a discussion http://weibo.com/1701018393/eCuxDrta0Nn. The first primary topic is: There is a machine, it has an IP, the above run a TCP service program, the program listens to only one port, ask: Theoretically (consider only TCP/IP this level, regardless of IPV6) This service program can support how many concurrent TCP connection?

JVM (which is the same process as compiling Java programs that generate Java bytecode)."Why do you use other implementations?" "You might be asking questions like that. Well, for developers, different implementations have different levels of support for various technical challenges.It's easy to write C extensions for your Python code in CPython because the C interpreter is ultimately executed. Jython, on the other hand, makes it easy to work with oth
