Insert a U disk into the computer's USB interface, and then in my computer to view the letter, into the U disk partition, create a suffix named LJ file any name, such as 123.lj
Next, create a batch file on the local disk and add the following statement to the batch file

Object-storage technology uses a scalable structure similar to that of a cluster computing system, and when storage capacity increases, it provides a balanced model to ensure that network bandwidth and processing capacity also grow synchronously, thus ensuring the scalability of the systems.The joint technical team in the Storage Network Industry Association (SNIA) and the T10 S

How to let the computer after inserting its own USB drive to start, or automatically shutdown after startup, the following is the implementation of the method:
1. First determine the USB disk letter, you can plug in your USB drive, and then you can see the letter, this step is very important, if the letter is wrong, then let your computer sleep;
2. Create a file in the USB drive, file name and extension are arbitrary input, such as the file created here is 123.LJ;
3. Create a batch file on th
USB disk to start the computer specific steps:
The first step: To determine the U disk is what the letter, this step is very important, if the letter is not correct, it can not be the right USB disk to start the computer.
The second step: a U disk in a random build a file, file name and extension can be casually written, such as: KKWJ.3FL can, this is equivalent to an encrypted password. Only this file U disk to start the computer.
Step three: Create a batch file with a. bat on this machine:
Today to teach a U disk special skills, you can allow the computer to insert their own USB drive to start, or after the start of the automatic shutdown, the following is the implementation of the method:
1. First determine the USB disk letter, you can plug in your USB drive, and then you can see the letter, this step is very important, if the letter is wrong, then let your computer sleep;
2. Create a file in the USB drive, file name and extension are arbitrary input, such as the file created h

Let the computer after inserting its own USB flash drive to start, or automatically shut down after startup, the following is the implementation process of the method:
1. First determine the drive letter, you can put your own USB stick, and then you can see the drive letter, this step is very important, if the letter is wrong, then let your computer to sleep it;
2. Create a file in the USB drive, file name and extension are arbitrary input, such as the author created a file of 123.LJ;
3. Crea
files: according to the search string hash (search string)%1000 large files into 1000 small files, each file about 2.5MB (retrieval string distribution evenly).
(2) For each small file, build a search string as key, the number of occurrences of value hashmap. Once the HashMap is set up, build a maximum heap of size 10 to find the T10 search string in each small file.
(3) The top 10 of each of these small files is synthesized, and the final top 10 res
We come back and take a serious look at the axioms (AXIOM) and univariate theorems listed above.
(for its proof, interested people can take a look, not interested can skip.) Here I prove (b) the T4: Because of A1 and its double-pair, we are dealing with binary issues. So according to A2 we do two times A2 operation, it is equivalent to the first operation of the A1, the second time A1 ' operation, the result is the original number itself. So the proof//)
So let's continue the multi-variable (m
Cause of the problem:
Most recently done project DB data volume is relatively large (basically one months of data is 1 billion), while the project proc parameter contains ID stitching string, id stitching string format: 1,2,4,5,100,301. When the amount of data is very small, there is no problem, but once the amount of data reached billion, the operation will be time-consuming, such as: when such a parameter ID stitching string contains 100,000 IDs (we actually have so many IDs to be uploade
