Maybe I will not achieve anything in the future, nor do I have a wealth of money or profit, or I may be mentioned, but why? I only wish to live every day in my favorite way and write every stroke of life carefully.
Let them all go. Remember Tagore's verse: "Don't miss picking flowers by the road. Because on this road, the flowers will continue to be open ."
I am still the original ME. Now, please do one thing with me: Close your eyes, take a deep breath, and forget me ...... (Write this ar
Kinetic Energy formula:
Momentum formula:
Conservation of momentum:
Conservation of energy:
According to these rules, the following equations can be obtained:
Solve the equations and obtain the following formula:
Subtract the two formulas to obtain:
That is:
We often use this formula to simplify operations.
Demonstration of basic momentum conservation:
First, add a quality "attribute" To The

Process:
We can see that the design process is:
1. Take the 8-byte dispersion factor, a hexadecimal string (you can set a fixed 8-byte number );
2. Call the identityauthentication function on the testzhuzhan. DLL interface to obtain the random number 1 and ciphertext 1;
3. Send the obtained random number 1 and ciphertext 1 to the electric meter, and the electric meter returns the 4-byte random number 2 and 8-byte Esam serial number;
4. Call the security authentication function

Fully in line with conservation of energy, the JavaScript spring vibrator of the Hulk theorem (ultra-simplified version, beyond the first version !) The last version used physical thoughts. This time it used mathematical ideas. If you have downloaded the first version of the code, you will obviously feel the power of mathematics !!!!!
Here is the JS Code of spring:
The Code is as follows:

Set ("Spark.shuffle.consolidateFiles", "true")Spark.shuffle.consolidateFiles: Whether to turn on merging shuffle block file, default to false// Set from Mapartitionrdd above to the next stage of the resulttask when the data transfer fast can be aggregated (the specific principle can be seen under the principle of shuffle and not set the difference)Spark.reducer.maxSizeInFlight:reduce task pull cache, default 48m//settings pull cache large, can pull more
