Php regular expressions (II): extracting html elements This article introduces the pattern modifier, greedy match, non-greedy match, Unicode mode, and surround view knowledge points in regular expressions by extracting html elements.

Introducing Kafka Streams:stream processing made simpleThis is an article that Jay Kreps wrote in March to introduce Kafka Streams. At that time Kafka streams was not officially released, so the specific API and features are different from the 0.10.0.0 release (released in June 2016).

The ListThe benefits of generics: It adds great potency and flexibility to writing object-oriented programs using the C # language. Performance is improved by not forcing boxing and unpacking of value types, or downward forcing type conversions on reference types.
Performance considerations:
