the corresponding record in accounts from B2, code: b2.select (accounts. ( ACCOUNT_NO). Pselect (~==customer_code)) a6=a5.derive (P.count ():p count,n.count (): ncount)This code adds a new column pcount,ncount in A5, which calculates the number of records for P and N in each set of data, and calculates the result as follows:a7=a6.derive (pcount/ncount:rate)This code adds a new column rate in A6, the algorithm is Pcount divided by ncount, and the result is as follows:

, there is no suitable software for simulation, so we will not give an example here. (4) TCP packet matching TCP is also one of the most important protocols in the TCP/IP protocol stack. It provides end-to-end reliable data streams. at the same time, many application layer protocols use TCP as the underlying communication protocol, because TCP matching is very important. If you want to match the HTTP communication data, you only need to specify a condition that matches port 80. Tcpdump 'tcp dst

The following is the difference between setting the number of cycles in a JMeter thread group and setting the number of loops in a loop controller JMeter generated script does not have STEP1 controller, so the loop is set in the thread group The Badboy recorded script has a SETP1 controller, so the loop is set in the controller Badboy a recorded script after removing the STEP1 controller fails to use the phenomenon Specifically why this situation, to be followed by the upda

instructions are based on these two pictures, the above is called a graph bar, the following is called B figure:Does it look like a tree? Yes, this is why it is called a tree-like array ~ First Look at a, an array is the array we want to maintain and query, but in fact we do not use the whole process of a array, you can think of it as a decoration! The C array is the center of attention and manipulation of our whole process. Let's take a look at the rules of the C array first, where C8 = C4+c6+

Quality exception ball problems in 12 small balls measured three times without Weight Balance Original Title:There are 12 small balls with the same features, and only one of them has a quality exception. It is required to be called three times without a weight to find the ball with an abnormal quality.Solution:Set the standard ball quality to W, and represent any normal ball. Number the 12 balls A1, A2,..., and A12 in sequence:A1, A2, A3, and A4 are A1 groups.A5, A6, A7, and
