According to foreign media reports, last weekend, the European Commission has accused Microsoft of violating the competition law by bundling IE browsers in Windows operating systems since 1996. Microsoft has issued a statement saying that its business activities always comply with EU laws and are currently evaluating the statement. Microsoft Ch

Below I have the function of the 8086 microprocessor as the end, briefly introduce the simple concept here, as to the specific stack operation and the concept of interrupt and working mode and some of the basic assembly language instructions they use, we have to introduce in the next article.

When we talk about compression, we may think of file compression. In fact, strings can also be compressed. PHP provides? Gzcompress () and gzuncompress () functions:

8. use gzcompress () to compress data

Gzcompress (), gzuncompress ()
These two functions are used to compress and decompress string data. Their compression ratio can reach about 50%. In addition, the gzencode () and gzdecode () functions can achieve similar results, but different compression algorithms are used.
Usage:
$ String =
"Lorem ipsum dolor sit amet, consectetur

Adipiscing. Nulla facilisi. Praesent pulvinar,

Compressed characters
When talking about compression, we usually think of files, such as ZIP structures. In Python, long characters can be compressed without any file.
