By the way, Netscape did not invent ssl, but also invented a lot of web-based facilities (css styles and JS scripts).Why is SSL this protocol invented? Because the original HTTP protocol used in the Internet is written in plaintext, there are many shortcomings, such as the transmission of conten

Garbage collection is used to achieve automatic memory management, which is different from manual management ). Problems with manual memory management: 1) suspension pointer, dangling pointer2) repeated recovery, double free3) Memory leakage, Memory Leak HistoryJohn McCarthy invented the concept and technology of garbage collection in 1959 and applied it to the List Language. In 1959, computer science was still in its infancy, but the great god has

SSL is the abbreviation for foreign language "secure Sockets layer", which is called "Secure Sockets Layer" in Chinese. It was designed by Netscape in the middle of the 90 century.

: latching and unlocking.1) The latching operation has two steps, respectively: Wait for the lock to reach the open state;2) Unlock one step: Open the lock.Note: The operation of the latch should be atomic operation, that is, can not be separated, otherwise it will leave the empty file interspersed, resulting in the failure of the lock. There is another problem here. Waiting causes a waste of resources, and may cause the CPU scheduling priority upside down, priority upside down is the high prior

of Linux think the image is too large, compression, and in the compression of the previous section, the addition of a decomposition compression code, constitutes a compression but the image is zimage (because the image size is just bigger than a floppy disk, (floppy disk has 2, 1.2M and 1.4m,image than 1.4M a little), in order to save a floppy disk money, so, The technique of compressing image into Zimage is designed.(4) Uboot in order to start the Linux kernel, also

simplest way is to count 10 toes, this does not solve the underlying problem.Our ancestors invented the carry system, which is what we call the ten-in-one today. This is a major leap in science for mankind. Almost all civilizations used the decimal, except for the Mayan civilization, where they counted all the fingers and toes before starting to carry, which was 20 binary. A century of the Mayans, which they called the solar age, was 400 years. 2012
