forwarding is divided into two types: local port forwarding and remote port forwarding. In fact, the two are similar, but the direction of ssh connection is different. For future convenience, we assume that there are three hosts A, B, C, and the hostnames are hosta, hostb, and hostc.
Local port forwarding
In local forwarding, a local port is forwarded to a port of another host, so that when our program connects to the local port, in fact, it is indirectly connected to a port of another host. w
samples to the line isIf all the sample points are projected onto a straight line, the covariance of the two types of samples isTo make the projection points of similar samples as close as possible, so that the covariance of the same sample projection points as small as possible, that is, to make the projection point of the heterogeneous sample as far away as possible, so that the distance between the center of the class as large as possible, that isBe

Incremental update policy: Data consolidation with a "update key" comparison of flow data records compared to records in the target table. Records with the same "update key" will be updated when the associated columns are not, and records that do not exist in the target table will be inserted. This method is used to manipulate the recorded changes when no recording is required.IKM compares records differently by using a method that is oriented to SQL programming instead of comparing rows by row-

resource isBe occupied.6. Key section and Rotary lockWhen a thread attempts to enter a critical segment, and the critical segment is being occupied by another thread, the function immediately switches the calling thread to the waiting state. ThisThis means that the thread must switch from user mode to kernel mode (about 1000 CPU cycles), which is a very expensive one. To improve the performance of critical segments,Microsoft has incorporated rotation
There are two types of MVC model templates: An edit mode (@Html. Editorfor ()), a display mode (Html.displayfor ()).Template acquisition and execution (the following is turned from here):When we call the HtmlHelper or htmlhelperDisplay mode or edit mode), the Modelmetadata object that represents the model metadata can be found by pre-createdThe template to be applied. If the template corresponds to a custom partial view, you only need to execute the view, and for the default template, you can di
