2. Go full stack + blockchain course:
a total of 22 weeks, divided into five stages,
the first stage is 4 weeks, go language foundation and network concurrency, learning the introctory go language,
the second stage is 4 weeks, go language practical web development, crawler development, cryptography, consensus algorithm, realizing lightweight public chain, learning the website and crawler that can develop golang, Achieve lightweight blockchain
stage 3, 4-week Ethereum source code analysis and smart contract DAPP development, master Ethereum core and smart contract development, as well as blockchain,
stage 4, 4-week super ledger, bitcoin EOS, source code analysis and smart contract practice, master super ledger development, cat bitcoin, bifurcated EOS after learning, As well as DAPP development of smart contract
phase 5, 6-week project practice, five enterprise level projects, and one year of blockchain project experience after learning
from the characteristics of the language itself, go is a very efficient language, which highly supports concurrency. Go language itself pays more attention to distributed system, and concurrency processing is relatively good, such as advertising and search, That kind of high concurrency server
go language advantages:
excellent performance, can be directly compiled into machine code, does not rely on other libraries, go is extremely fast. Its performance is similar to Java or C + +
concurrency is supported at the language level, which is the biggest feature of go. It is born to support concurrency, and go is the concurrency supported in gene, which can make full use of multi-core and make it easy to use concurrency
the built-in runtime supports garbage collection, which is one of the features of dynamic language. Although GC is not perfect at present, it is enough to cope with most of the situations we can encounter, especially GC after go1.1
it's easy to learn. The authors of go language all have the gene of C, so go naturally has the gene of C. There are 25 go keywords, but the expressive ability is very strong. It almost supports most of the features you've seen in other languages: inheritance, overloading, object, etc
rich standard libraries, go has built a large number of libraries, especially the network library, which is also my favorite part< As like as two peas, br / > built-in powerful tools, Go language is built with many tools chain, the best should be gofmt tools, automatic formatting code, make team review become so simple, code format is exactly the same, it is very difficult to think differently.
cross platform compilation and fast compilation. Compared with the sluggish compilation speed of Java and C + +, the fast compilation time of go is a major efficiency advantage
disadvantages of go language:
package management: package management of go language is absolutely not perfect. By default, it has no way to make a specific version of the dependency library, nor can it create replicable builds. In contrast, python, node and Ruby all have better package management systems. However, with the right tools, the package management of go language can also perform well
lack of development framework: go language does not have a major framework, such as Ruby's rails framework, Python's Django framework or PHP's laravel. This is a heated discussion in the go language community, because many people think that we should not start with using frameworks. This is true in many cases, but if you just want to build a simple crud API, it's much easier to use Django / djrf, rails laravel, or Phoenix
exception handling: go language can help developers deal with compilation errors by simply returning errors (or call stack) through functions and expected calling codes. Although this method is effective, it is easy to lose the scope of the error, so it is difficult to provide meaningful error information to users. Error package can solve this problem by allowing us to add context and stack trace to return error
another problem is that we may forget to handle errors. Static analysis tools such as errcheck and megacheck can avoid these errors. Although these solutions are very effective, they may not be the right way.

5. In the first half of Tencent's blockchain security report, technical experts believe that the current security problems caused by blockchain cryptocurrency mainly stem from three aspects: first, the mechanism of blockchain itself. There are loopholes in the design of blockchain smart contract represented by Ethereum, which brings serious economic losses
6. Depending on your basic level, if you have a certain technical foundation for development, it is relatively easy to learn
"chainman College" offers short weekend technical training courses for colleges with a certain programming foundation. You can investigate them and ask about your situation.

it has been four days since the end of postgraate entrance examination, After a few days of natural and unrestrained time, I still want to share with you some of the process of my postgraate entrance examination. In the past half a year, many people thought that I spent most of my time on the postgraate entrance examination. In fact, I did some other interesting things. For example, in the postgraate entrance examination process, I went to participate in the computer design competition, also honored to win the national first prize, still a little proud. Now let's get down to business. Let me talk about the experience of participating in the competition As for the experience of the postgraate entrance examination, I would like to share with you after the results of the preliminary examination)
as a senior who participated in the two competitions, I want to tell you that this competition is still very routine, and once you master the routine, it is good to win the prize
about the judges and evaluation criteria of the competition: it is worth noting that the evaluation criteria of the judges of the school competition, the city competition and the national competition are slightly different, so naturally the results are also very different, but the evaluation of the school competition and the national competition are similar, and the standards of the city competition are slightly different. In fact, the author thinks that there are two main points in game planning: innovation and algorithm. In particular, the city competition pays more attention to the compilation of algorithm, while the national competition pays more attention to innovation. What's more, it's worth noting that many of the judges of the National Games are professors of the older generation, so we have to figure out how to convince the judges of the older generation that your project is very practical and important
suggestions on topic selection: I believe there are still many students who still don't know what to do or where to start, so I want to tell you that the judges of the national championship are aging, and most of them like to see some relatively new technologies and topics. So we can combine the hot technology on the market with our daily life to determine the goal of our software. For example, this year's competition software of the author is an attendance system that applies living face recognition technology and geographic information positioning to class roll call. It also uses NLP natural language processing and emotion recognition of network AI to make a comment system, which mainly solves the problems of absenteeism rate, late rate and substitute rate in our daily learning; A friend of the author also won the first prize for a system with the characteristics of blockchain, bill market and Finance University. So I still suggest that you use some new technology now, and make a useful system with a problem in your life. Remember to be new. If the topic is not new, the teacher will easily ask why I want to use your software instead of the more mature software on the market
about how to learn and choose novel technology: the author here can provide you with some relatively novel technology websites for you to consider, and there are many ready-made APIs for you to consider. 1. Internet AI, website: http://ai..com/ 2. Tencent AI, website: https://ai.qq.com/ 3. Ethereum, website: https://ethfans.org/ 4. Turing robot, website: http://biz.turingos.cn/home 5. Tencent big data platform, website: https://data.qq.com/ 6. Knowledge workshop, website: http://kw.fudan.e.cn/ . Readers recommend that you consider the knowledge workshop. After all, knowledge mapping is a hot topic, which can be well applied to practical projects, and it can be done in a dazzling way. Few people who participate in the competition use knowledge mapping, which is a relatively new technology
about team division: This is a very important point. Because the general project team has three people, so in my opinion, the best match is a front-end, a back-end, a dedicated document writing Document writing is really troublesome)
front end: if you participate in the design of the web site, the author's suggestion is that you should at least use a simple version of the mobile terminal, because in the first year of the competition, the author was asked: now is the era of mobile Internet, your idea of this project is OK, but it's too troublesome to use. So the next year, the author made a mobile terminal (small program), and the judges didn't say that we were inconvenient to use. For the proction of mobile terminal, the author's suggestion is to make a small program, because the small program is really easy to learn, and the code is very similar to HTML, CSS and JavaScript. It's very simple. The key is that its advantage is that it is suitable for both Android and IOS App learning website: https://developers.weixin.qq.com/miniprogram/dev/index.html
back end: I suggest you still use the framework to write code, because it's really convenient to use the framework. Many predecessors have written a lot of very useful interfaces in advance, such as the storage of pictures, videos, etc., if you use the native code to write, If you don't use the cache, it will run very slowly, but if you use the framework, there won't be such a problem, because the predecessors have designed excellent ready-made interfaces for you to use, and you can learn from the source code they wrote when you have time. The most important thing is that the enterprise recruits people who can use the framework. Of course, I'm not saying that the original is not good. The original is an internal skill, and we should pay attention to it. However, there may be some problems in the learning of framework at the beginning, but I believe you can solve this problem very well! Here I recommend you to learn several frameworks: ThinkPHP, Django, springboot. The first two are relatively easy to learn, which are PHP and python frameworks, while the latter one is relatively difficult, which is Java. For those who want to learn crawler, they can learn Django, because it is very similar to the crawler framework scrapy, which is easy to master at the same time. It is said that Django and scrapy are developed by the same development team, so they are very similar. Of course, I just heard that I don't know what the actual situation is, hahaha
documents: the preparation of documents is really cumbersome, because there are many documents, so it's better to have a special person to write documents, especially to be able to build UML diagrams, mind maps and so on. When writing a document, you must pay attention to the time node. If you miss the time node, it's a pity
about programming language learning: I believe many students can't find a better programming language or framework learning website at present. Here I recommend several websites that I think are better: 1. MOOCS website, website: https://www.imooc.com/ 2. Laboratory building, website: https://www.shiyanlou.com/ 3. MOOC of China, website: https://www.icourse163.org/ 4. CSDN, website: https://www.csdn.net/ 5. GitHub, website: https://github.com/ . Now, we need to buy money in the Mogao class network and the experimental building. We need to buy money now. It's more expensive. You can go to salty fish and turn around to find a screen lesson. A treasure has been forced by some treasure official account. Of course, if you really can't find it, you can ask me some frames of learning videos in the background of public numbers. I still have some video stock of courses. The disadvantage of Chinese MOOCS lies in its timeliness. It can't be seen after the learning time of the course. It may be to protect teachers' rights and interests of knowledge labor. CSDN is very important. For beginners, CSDN should be able to cover all your problems. GitHub, as we all know, is mainly used to search for ready-made projects to learn other people's ideas of building software, or to search for some useful plug-ins, such as IP agent pool and fake user agent, which are commonly used in crawlers.

8. Recommend an introctory book, blockchain, written by Zhang Jian, and then you can read more information about blockchain. In fact, you can understand the current market. If you want to speculate in money, you can download a blockchain app store first, which collects all the necessary software for money speculation in the market, including trading house, wallet, information, community and other software. It is not particularly convenient for users who want to get started. You can search the Internet for beestore.
9. It mainly depends on the personal foundation. It's less than three months fast.
