My Beaglebone black before installing the Ubuntu 14.04 System, the use of the process found in the Ubuntu system under the serial device TTYS1~TTYS5 can not be used, open the serial port will show input/output error, I guess there may be no driver or any other reason, younger brother compared vegetables, so did not find the reason, also did not solve.My solution is to brush back to the factory is the operat

Recently in the Linux kernel to learn the red and black tree, found on the site is not a good example of the visual expression. Referring to the techniques of some great gods on the Internet, finally inThe terminal realizes the visual expression of the red-black tree.The red-black tree Code We used this time was copied

sortable key/numeric data. It is different from the cardinality tree (used to efficiently store sparse arrays, so using long integers strands insert/access/delete nodes and hash tables (it can easily be sequentially traversed without sorting, but you have to set the specific size and hash function, while the red-black tree gracefully extends the storage of any key) Red-black trees are similar to AVL trees,

Many people are learning about the Linux operating system. We encounter many problems when learning Linux. I recently looked at Linux memory management and saw that the red/black tree was very big. So I learned the basic knowledge of the red/black number.

Why did Linux use the AVL tree earlier and then prefer the red-black tree?In fact, this is the result of the pragmatism of the red and black tree, and this essay remains a metaphysical point of view. Red and black trees can be exported directly from 2-3 trees, we can no longer mention the red and
