DescriptionThe 15-puzzle has been around for over 100 years; even if you don't know it by that name, you 've got it. it is constructed with 15 sliding tiles, each with a number from 1 to 15 on it, and all packed into a 4
4 frame with one tile missing. Let's call the missi
animation was executed, it basically ended. Later, I was slowly rubbing for more than one second, the county is not smooth .. Then I changed it to the second one, y =-x + 100. The effect is better, but it is too smooth .. Click it to fly far away .. After adjusting the sensitivity with AA, the effect was still unsatisfactory, so I watched the effect that Apple brought in for half a day and found that the speed was slowing down quickly, the change degree of the absolute value of acceleration see
:
Trigonometric function: sine and hyperbolic sine. According to inv, we can calculate the inverse sine of the inverse function, which is also true for cosine and tangent. In this way, there are a total of 12 functions in 4*3.
Algebraic functions: power functions (X2, X3, X1/3, XY, X1/y) learned in high school algebra, logarithm functions (in, log), factorial (N !), Exponential Function (10x)
Others: some functions are used in program

than the limit, and the detailed performance is still not very good. The texture of the instrument, especially the wind instrument, is still very hard and not true, lack of music, the size after compression is 128 kb, I think the compression ratio is ~~ The m MP3 player is better than the 10X player, which can satisfy both the main listening experience and the proper size. The M player can store music for about 95 minutes, 190 m doubles to minutes of
things using the simple event data model shown above. The event data model has a few special qualities:
1. The data is rich
2. The data is denormalized
3. The data is nested
4. The data is schemaless
Event Data is rich
This death event has a lot of properties-information about the player at the time of death, the cause of death, the enemy. events can have hundreds of properties; they seek to describe not just one entity, but all of the entities involved in an action.
In fact, I think we shocoul

cursorWord word indicates that a character is searched for a character above the cursorN (English character) is the/word of the previous action. Word is searched againN (English characters) and N are the opposite: n1,n2s/word1/word2/g N1 and N2 are numbers that are found between N1 and N2 rows Word1 use Word2 instead: 1, $s/word1/word2/g represents the use of word1 instead of word2 between the first and last lines: 1, $s/word1/word2/gc and above are the same meaning but will be user determined
derivative of the equation. Written by the user.
(2) convergence speed of the Newton Iteration Method: IfF (x)There is a continuous Second-Order Derivative Near zero.F (x)And the initial value x0 is close to that of ε, So Newton Iteration converges, and its convergence speed is second-order, that is, the square convergence speed.

different focal lengths. This is an optical fact. Believe it? Then a specific test is performed with one 35mm shot and one 200mm shot. First, use a long camera to photograph a friend standing next to a long fence filled with flowers. Then she switched to the wide-angle camera and approached the shooting, so that she was as big as the previous image in the viewfinder. Observe these slides with a 10x magnifier and you will find that the acceptable clea

It is very helpful to use/word with n and N! You can repeat to find some keywords you are searching!
: N1, n2s/word1/word2/g
N1 and n2 are numbers. Search for the word1 string between line n1 and line n2 and replace it with word2! For example, if you search for vbird between 100 and 200 and replace it with VBIRD:": 100,200 s/vbird/VBIRD/g 』. (Common)
: 1, $ s/word1/word2/g
Search for the word1 string from the first row to the last row and replace it with word2!

document. I think that's why MongoDB cannot use join table queries ~MongoDB 2.8 (version 2.8 jumps directly to version 3.0. Why do we name 2.8 3.0? Tang jianfa said that 2.8 had been greatly enhanced, and 2.8 was a bit grievance. Therefore, the MongoDB Marketing Department named 3.0 .) The version introduces the WiredTiger storage engine MMAP that supports Latch-free and Non-blocking algorithms. Therefore, the wiredtiger parameter must be added before use.

works in a big project group. The most efficient programmer in the group is a guy with a high-bit paralysis and his mouth hitting the code with a stick, he always thinks carefully and rarely makes mistakes before writing code." 9. Neat code is better than clever code If you want others to understand your code, try to use the least code to complete the task. Follow the dry (don't repeat yourself) principle and use clearly defined objects and libraries to break down tasks into small and simple
