(Tip: Why do you compress CK?) Because the actual situation of transaction records are often stored on the external storage, such as databases or other formats of the file, in each calculation of the candidate count will need to compare the candidate with all transactions, it is known that access to the external memory is often relatively low efficiency, so Apriori joined the so-called pruning step, The candid

1, how to choose the CPU?
CPU is one of the core hardware of the computer, which determines the computing power of the computer. Today, both Intel and AMD have introduced a new generation of architecture products. One of the next generation of CPU the biggest bright spot is to greatly enhance the core graphics performance, for the general just play the popular network game students friend, the next generation of mainstream CPU completely with
Pre-launch environment testers found that the disk space is covered, so use df-h and Du-sh * found large files, and delete.But did not free up space, df-h or display occupancy rate is 100%, at this time du-sh * Display occupies only 7G, and Df-h looked at the content does not match.In Linux or Unix systems, deleting files via RM or the File Manager removes the link from the file system's directory structure. However, if the file is consumed by the program, it cannot really clean up the disk spac
