priority of the signalThe signal is essentially a soft interrupt, the interrupt has a priority, and the signal has a priority level. If a process has multiple pending signals, the kernel will deliver the signal in the order it was sent for the same pending real-time signal. If there are multiple pending signals, the smaller the value (or number) is delivered first. If there is an unreliable signal, and there is a reliable signal (real-time signal), although POSIX does not explicitly stipulate t

frames? Just to offset the benefits of packet switching?? In fact, this is for the host optimization, especially running Windows host, this host is generally at the edge of the network, as end-to-end processing, so for the arrival of the data frame, if the interruption is too frequent, will inevitably reduce the application layer processing performance, after all, the total resources are limited! Jumbo fra

Summary PLSQL _ performance optimization series 11_Oracle Bulk Collect There is an overhead for running SQL statements in PL/SQL programs, because SQL statements must be submitted to the SQL engine for processing. The transfer of control between PL/SQL engine and

a set of "system Keys". These keys are usually a combination of [alt] and other keys. The system Keys have specific functions for Windows systems, in Windows, the following message is also specified for system Keys. Wm_syskeydown press system key message Wm_syskeyup Panasonic system key message "Sys" is added to the message code to indicate that the system key presses the message. However, in fact, the program rarely processes the system key message, because when such a message occurs, Win

Transaction Processing and concurrency control, transaction processing Concurrency Control What is a transaction? Is a mechanism, an operation sequence, it contains a group of database operation commands, and all the commands as a whole, together to submit or cancel the operation request to the system. It consists of one or more SQL statements that complete a related behavior. Is an inseparable unit of work

Batch Processing and python code mixed programming method, batch processing python Batch processing can be easily mixed with other languages for programming. In addition to being fun, batch processing also has considerable practical value. For example, the windows ruby gem Package Manager uses batch

The original Article is not a trilogy, but a series of articles that explain the basics of javascript. I'm pumping out three of them, as a whole, to understand the event binding model is quite helpful, the original article here http://www.quirksmode.org/js/events_early.html Today I will explain the earliest method to add event handler functions, which is even in the second-generation browser (Version2 Browers)Also supported Early browsers supported only one function binding method, which was inv

generate more tuples in the downstream trigger: each word in the sentence forms a tuple and the count of each subsequent word forms a new tuple. The following is a tuple-composed message tree, or a tuple tree: When the tuple tree is fully used and all the messages in the tree have been completely processed, Storm thinks that the tuple (the tuple is the root node in the tree) spout is "fully processed". And when all the messages in this tree are not fully processed within a certain time, Storm

When doing image processing, it is sometimes necessary to process only one particular region of the image, rather than the entire image. For example, to the user selected a specific area for the mean filter or contrast enhancement, MATLAB can only be specific to the region to deal with.
