time record the price difference between the two transactions, the price will be at least a difference of 10 yuan.6, if the market fluctuation in a narrow range, then the trade alternately, the middle will generate profits.7, if there is unilateral market, how to carry out the sale? For example, 2000 yuan to sell a bitcoin, while in 1990 to hang a buy order, then the price continues to rise, a short period of time will not fall back to

Lucene takes field as the Key-value storage unit, and the value of field can be stored as string, int, long, double, float, and byte[], and it is often necessary to store complex data types such as list, map, and so on during development. Here's how to convert a complex object to a single Key-value store into Lucene.Lucene supports multi-domain value storage, the same document can store multiple keys of the same field, the simple understanding is Lucene support Key=value and Key=[value1,value2]

The previous blog introduced the use of the simple query API in ES, and this article describes the use of the aggregation API provided by ES. The aggregation capabilities provided by ES can be used for simple data analysis. This article is still an example of the data provided above. The data are as follows: Studentno name male Age Birthday Classno Address Isleader 1 Liu bei Man 24 1985-02-03 1 Hunan Governor Shas

The history of Web discussions on Web development technology, of course, is to start with the origins of the Web. As we all know, the most popular application architecture on the internet is invented by Tim Berners-lee. The web was formerly the enquire (enquire Within Upon Everything) project by Tim Berners-lee in 1980. The first Web server, nxoc01.cern.ch, started running in November 1990, and Tim Berners-lee saw the earliest web page on the "WorldWi

columns first. If name the values of the columns are the same, they are birthday sorted by the values of the columns. If the birthday values of the columns are also the same, the phone_number values are sorted by. This sort method is very, very special, very, huge, very very very important, because as long as the nodes and records are in order, we can use the dichotomy to quickly locate the search. The bottom of the content depends on this diagram, we understand the picture.2.1 Fu

Sometimes a partition function is built on the job, but a partition function like a date can have a value of hundreds of if it's not going to kill me. So I wrote a bit of code to automatically generate a monthly partition function and a corresponding partition theme starting from 1990.

In Excel, you sometimes need to combine the contents of two cells with a formula, and you can use the connector. However, if two cells are text and dates, for example, if you include a date "May 1, 1990" In Cell E15, you now want to display the words "Lidong's birth date is May 1, 1990" In another cell, if you use the formula directly: = "Lidong's birth date is" e15 The formula will return "Lidong's birt
