IDE bitcoin

1. Do you want to learn blockchain development technology or just want to know what blockchain is? If it is the former, you can look at the code of other blockchain projects and learn about it first. If it is the latter, we can pay attention to some good blockchain we media. Blockchain is an emerging instry. There is no ready-made training course. It depends on self exploration and understanding.

2. Now that you use hub to connect two computers to the Internet at the same time, the two computers are already in the same bureau network, but they can't see each other in the network neighborhood, right?

3. Many projects belong to the new infrastructure category. Just take the procts and solutions launched by lierda group as an example: (information communication, 5g and other infrastructure network construction) lierda lorawan solution has low power consumption, strong anti-interference, low cost and high capacity; Lilda NB IOT solution has wide signal coverage, strong penetration ability, ultra-low power consumption, ultra-high sensitivity, strong anti-interference and low cost Smart city, municipal pipe network) has a mature underground parking energy-saving lighting system to rece lighting costs, system rability and reliability, save maintenance costs, improve management efficiency Artificial intelligence) Intelligent Hotel solutions meet the personalized needs of customers and make the hotel management service more efficient and orderly

4. As the most widely used programming language in the world, Java is always used to compare with Python. Moreover, Python and Java are also the most popular among all kinds of programming languages
1. Java must explicitly declare variable names, while python of dynamic type does not need to declare variables
2. Python is a powerful language with simple syntax, which can provide excellent solutions by writing scripts, and can be quickly deployed in various fields
3. Java can create cross platform applications, while Python is compatible with almost all current operating systems< For beginners, Python is easier to learn than Java, and the code is easy to read
5. Speed, Java and python are not suitable for high-performance computing, but in terms of performance, Java is slightly better than python. The efficiency advantage of Java is reflected in the virtual machine execution. When the program is executed, the JVM can convert the bytecode into local machine code. This kind of just in time (JIT) compilation makes Java slightly better than python, but Python adjusts the performance to improve the efficiency of Python
java and python are both dynamic programming languages, which are associated with openness, so it is better for companies, teams and programmers to keep an open attitude when making decisions. As for which programming language programmers should choose, we can compare them by combining the above five points, but more programmers seem to prefer python. After all, python has better prospects in the fields of artificial intelligence, data analysis, cloud computing and so on!

5. Virtual currency won't write formulas like stocks. bitcoin has gone bankrupt. Please be careful. You can support your own Chinese currency

6. From bitcoin to Ethereum, it seems that more and more institutional traders are interested in accumulating Ethereum for long-term benefits, because Ethereum is also a store of value

1. Ethereum: a better value accumulation target

for many years, accumulating bitcoin has been the main way to store the value of cryptocurrency. Investors use bitcoin as a sharp weapon against the economic crisis. However, institutional traders are now also interested in Ethereum

in the 2020 annual review report of coinbase, it is noted that institutional customers are more and more interested in Ethereum. The reason is related to how investors evaluate Ethereum ecosystem

first of all, it is the original currency of the network. Because Ethereum is a platform for many valuable projects, Ethereum has become a powerful trading currency in Ethereum ecosystem

Why are more and more institutional traders hoarding Ethereum

the report points out that the driving force for Ethereum holders to invest comes from: first, Ethereum's potential as a value store is constantly developing; 2、 Ethereum's status as a digital currency provides the basis for its network transactions<

2. Investment institutions such as coinbase and Gemini are optimistic about Ethereum and defi

Arthur Cheong, founder of definance capital and portfolio manager focusing on defi encryption fund, pointed out in a statement in coindesk, "I think bold investors will explore Ethereum and defi after studying bitcoin."

according to the data, some investment institutions such as coinbase and Gemini are incredibly bullish on Ethereum. In addition, more and more large investors are looking for different decentralized financing space

Why are more and more institutional traders hoarding Ethereum< However, deniss vinokourou, a digital asset investment manager, believes that "not everyone is satisfied with the risks associated with defi that still exist, but the rapid growth of active projects in Ethereum supports capital appreciation."

unlike bitcoin, Ethereum has many ways to retain investors and lock them in for a long time. After the release of eth2.0, Ethereum owners have made a lot of profits in long Ethereum

8. 1、 Python virtual machine is not as strong as Java. Java virtual machine is the core of Java. The core of Python is that it is easy to use C language functions or C + + libraries< Second, Python is fully dynamic and can modify its own code at runtime. Java can only be implemented through flexible methods. Python variables are dynamic, while Java variables are static and need to be declared in advance, so the code prompt function of Java IDE is better than that of Python ide
Third, python has been proced for decades, and process oriented design was the mainstream decades ago, so many programs in Python use process oriented design methods, many concepts come from C language, class is added later in Python, and Java is used to realize c + + without pointer (reference counting used by com components in those years, virtual machine used by Java), It mainly adopts object-oriented design method, and many concepts are OOP concepts. Process oriented, relatively simple and intuitive, but easy to design noodle program, object-oriented, relatively abstract and elegant, but easy to over abstract
Fourth, it's easy to get started in the actual use of python, but to learn how to work with Python, you need to learn all kinds of Python libraries. The strength of pyhton lies in the library. The reason why the library of Python is powerful is that the library of Python can be designed with Python, C language, C + +, and then provided to python, so no matter how GPU runs, neural network, intelligent algorithm, data analysis, image processing, Scientific computing, all kinds of libraries are waiting for you. Java does not have as many open source libraries as python, many of which are used internally by commercial companies, or released as a jar package without the original code. Because the compiler of Python virtual machine is not as good as that of Java (or designed intentionally), it usually directly uses the source code (Linux), or simply packs the source code (such as pyexe)< 5. There are many virtual machine implementations in Python, such as python, python, pypy, Jython, ironpython, etc., which are suitable for business language, plug-in language, or domain oriented language, while Java is rarely used for plug-in language because of its huge size, and it is not convenient to publish< 6. Java is mainly used in the fields with strong business logic, such as mall system, ERP, OA, finance, insurance and other traditional database transaction fields. Through transaction codes similar to SSH framework, Java has better support for business databases, such as Oracle, DB2, SQL server, etc., and has strong software engineering concept, which is suitable for multi person development mode of software engineering. Python is mainly used for web data analysis, scientific computing, financial analysis, signal analysis, image algorithm, mathematical calculation, statistical analysis, algorithm modeling, server operation and maintenance, automatic operation, rapid development, strong concept, suitable for rapid development team or indivial agile mode< 7. There are many commercial companies supporting Java, such as SAP, Oracle, IBM, etc. there are commercial containers, middleware, enterprise framework and EJB. Many open source organizations support python, such as QT, Linux, Google, and many open source programs support python, such as pyqt, redis, spark, etc< 8. Python is most used for scripting, Java is most used for web, Python is glue, which can glue all kinds of irrelevant things together, Java is fag, which can form hundreds of personal teams and PK with you through software engineering, with strong commercial flavor. However, I think Python is still powerful, because it can easily call C or C + + libraries, but software engineering and commercial operation are not as good as Java, so it is suitable for rapid development< Nine, about money
if you want to write a program to sell software with Java, you can use IBM server, Oracle database, and EMC storage. The price is high, and commercial purchasing companies like this kind of high-end software. If you want to generate money directly with the program, you can use Python to realize kuanke finance, data back testing, stock speculation, option speculation, gold speculation, bitcoin speculation, hedge arbitrage, statistical arbitrage. There are many open source libraries, data analysis libraries and machine learning libraries for reference< 10. Java and python can run on Linux operating system, but many Linux can support Python natively, and Java needs to be installed by itself. The reason why Java and python are better than C # is that they support Linux, OSX, UNIX and arm. The reason why Java and python are more popular than C + + is that they don't need pointers< For mobile Internet, python can only run on Android or IOS through runtime. Java supports Android development, but not IOS< 12. For big data, it is more convenient to use java to open Hadoop, Scala to develop spark, and python to call spark for further analysis.
