What is the-ETF in the Qianhai fund?Abbreviations are really a wonderful thing. "Trading Open index Securities Investment Fund" (Exchange traded Fund) such a long name can be simplified to three letters of the ETF. And people who know a little bit about it can make more or less associations and extensions to the features behind it as soon as they see the three letters.As an index fund, ETFs are very discipl

Label:ollydbgis a 32-bit assembly-analysis debugger with a visual interface. What makes it special is that it can solve problems without source code, and can handle problems that other compilers cannot solve. Version 1.10is the final release version. This project has been stopped and I am not going to support this software anymore. But don't worry: the newly crea

specific person, the same truth, in object-oriented programming, it is the object that is directly related to the business, not the class, but the class is used to define the shape of the object, how to define it? The variables and constants in the class indicate what kind of properties the object will have after this

Twisted (1) -- What is asynchronous, twisted -- What is asynchronous I have long wanted to write an article about python's two asynchronous libraries, twisted and tornado. When developing python tcpserver, we usually only use three libraries, twisted, tornado, and gevent. The efficiency of asynchronous libraries repres

software design patterns, so let me briefly describe the most common MVC pattern.The MVC pattern was proposed by buschmann in 1996:Model: encapsulates data and all operations based on the data.View: encapsulates the display of data, that is, the user interface.Controller: encapsulates operations on the model and controls the flow of data. In addition:The Unified Process of software (Rational Unified Process), XP (eXtreme Programming) Extreme Programm

understanding, should be just a virtual mapping table, is actually just an algorithm. Take a line from 936, for example: 0x9993 0X6ABD #CJK Unified Ideograph The preceding encoding is GBK encoding, followed by Unicode. By looking at this table, you can simply implement the conversion between GBK and Unicode. Now that we understand Unicode, then what

, It's as simple as opening QQ under Windows. And in fact, that's the case.You know, these are not what the BIOS can do. Because the system boot code (included in the master boot record) must be read from the specified sector on the hard disk before booting the operating system under the BIOS, boot the operating system from the active partition. The operation of the sector
