XMPP and xmpp protocolsXMPP-instant messaging technology Overview
(IM -- Instant Messaging) supports real-time online conversations. If you want to send a message, you need to open a small window so that users and their friends can enter the information and both parties can see that there are many IM systems in the conversation content, for example, AOL, Yahoo IM, MSN, and QQ, the biggest difference lies in the implementation of their respective communication protocols, therefore, the core of in
the pain by making simple annotations. After installing Docblockr, all you need to do is start a line of code with/* or/**, and the rest will be handed to it. If you start with/** on the function, it will generate comments for you based on the JSDoc format. There are things that you have never used before, but once you've used them, you'll wonder how you've survived, and Docblockr is one of those examples.Docblockr supports many other languages, including: Coffeescript,typescript, PHP, ActionSc
living cells in the surrounding 8 squares, the cells are resurrected.
Cells located at the edge and apex of the entire grid may have fewer than 8 cells around it. That is, there are no more cells beyond the boundaries of the grid.
The changes in the life and death of each cell will not affect the cells around the current step, but will only show up in the next stage.

The scores of several programming languages in the top of the rankings have long been declining: Java and C have been relatively low in the Tiobe list. And almost all the other top ten languages are falling every year.So which language captures this opportunity? This happens in the leaderboard about 40 bits.The rankings of some new languages are rising, especially crystal (32), Kotlin (41), Clojure (42), Hack (43) and Julia (46). Crystal's performance was particularly good, jumping from 60th pla

Karate ClubThis is a network of social relationships with 34 vertices and 78 edges. The edge of this network represents a mutual understanding among members of a karate club in a university.The NCAA Schedule NetworkThis network consists of 115 vertices and 613 edges. The apex represents a college football team, which represents a match between the football teams during the 2000 season. Both networks are standard test sets for graph clustering algorit

Transferred from: http://blog.csdn.net/heliang7/article/details/7309394The main question is how to calculate the length and width of the new image after the image has been rotated.With the help of Java 2d and the basic math library, you can actually use simple calculations to know.The following algorithm only calculates the formula when the rotation is less than 90 degrees. When the rotation is greater than 90 o'clock, the problem domain can be converted to a sharp angle, and then calculated.As

Meaning
For a tree n nodes, the node number is 0~n-1, and the vertex is 0.
Each side has a weight value.
Alice and Bob start at the apex and go down to the leaf node.
The first time is from Bob to choose which child knot, the second turn to Alice, in turn go down ...
Each edge gets the right value, and Bob hopes that the bigger the path, the better, and that Alice hopes the smaller the better.
Each time they will choose the optimal solution.
