Zhang Xiaolong's blockchain

1. blockchain: it is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

blockchain is an important concept of bitcoin. According to the 2014-2016 global bitcoin Development Research Report issued by the Internet Finance Laboratory of Wukou School of finance, Tsinghua University and Sina Technology, blockchain is the underlying technology and infrastructure of bitcoin [2]. In essence, it is a decentralized database, as well as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

2. Big data: refers to the data set that cannot be captured, managed and processed by conventional software tools within a certain period of time. It is a massive, high growth rate and diversified information asset that needs new processing mode to have stronger decision-making power, insight and discovery power and process optimization ability

How long is the history of computer development? In the true sense, the birth of computer is only 80 years ago. 80 years, for everyone, is a long time, but for the whole history, it is just a moment

in 2017

alphago zero beat alphago 100-0

every event written in the last

Article was only mentioned once, but at that time, none of them was an important milestone of computer and Internet. Since the birth of the electronic computer, throughout the 80 years of history, there are countless wisdom and dreams

This article is from the author Dan Hua who shared my 10 reading strategies on gitchat

editor MC Jin

why reading also needs strategies

don't you read what you like? Do you also need to "play the mind" in reading

of course

the leisure and entertainment reading of novel literature, of course, does not need strategy, just follow the feeling

in order to solve a specific problem of reading, such as need to learn a tool, also do not need strategy

when you want to gain something, dig deep in one direction, and win the competition, you need strategy

most of the strategic reading is utilitarian. There are specific cognitive demands for books and doubts to be solved. In the current society with fierce competition and rampant anxiety disorder, many people try to improve their ability by reading. However, few people take "reading" seriously and think about and establish their own "reading strategies"

therefore, paying attention to reading strategies and reading strategically will become a powerful competitive weapon you have. Especially for introverts with poor social skills and low EQ (such as me), reading has a al function: it is not only a haven, but also a new battlefield

reading strategy 1: strong sense of competition

when you search a good book and find hundreds of comments, it's impossible not to panic: there are so many bitches running in front of your grandfather

KK's out of control was first discovered in 2011, and the old version of out of control just came into the market. If you get the treasure, you can warmly recommend it to the people around you. Many people don't know who KK is

in August and September 2012, it came out that Zhang Xiaolong strongly recommended the book on wechat, so it became popular all over the country

all of a sudden, you find that everyone is reading the original martial arts script you have, and it may be more serious and deeper than you

my thought at that time was that most of them were aimed at Zhang Xiaolong's fame, or because of the Internet

this book led me to have a deeper understanding of the ecosystem of nature and the market economy, which directly led me to understand and seize the opportunity of bitcoin later on. After contacting bitcoin, you will immediately be convinced that this is the future

reading strategy 2: reading general knowledge

all knowledge can be abstracted as a big tree, including abstract trunk knowledge and specific leaf knowledge. There is no doubt that you should read the trunk first and absorb as much as you can the best and most common knowledge of all subjects / fields. P>

this is the grille theory recommended by Munger: extract the essence from all fields, connect with each other, and weave into an efficient, explanatory knowledge grid, and use it as a weapon to deal with the complex external world. p> Munger said that there are about 100-200 such models. I think everyone can set them according to their own situation

what is general knowledge

in the field of Internet, long tail effect and out of control

in a broader sense, evolutionism is also universal knowledge, whether in the field of life science or social economy. Munger and ray Dalio have described this

in the field of psychology, "influence" and "social psychology" by David Myers are bound to count, as are "mobs" Influence and the mob are more popular with a large number of readers

when I realized the importance of social psychology through influence and the mob, my natural idea was to find a more comprehensive and authoritative work on social psychology, so I found Myers' social psychology

it's a textbook. Many people think it's boring, with ideas listed and poor readability. What's more, it's very heavy. However, I got the best of it at that time. Even when I was on a business trip, I resolutely put it in my bag and chewed it page by page on the plane and in the hotel

I'm willing to read this book because it's an academic textbook full of dry goods and seeds. Many people can't finish it, so I have to finish it and confirm that I want to dig the gold in it

by seed, it means that there are many profound concepts and viewpoints that are worthy of further exploration. For example, "self service effect" is a good seed. People who are familiar with Munger should have heard of this concept. Munger's favorite example is that 80% of taxi drivers think that their driving level is above the average level

this conclusion holds for any other occupation, such as investors

reading strategy 3: read those books with dry goods but poor readability

as you can imagine, most best sellers meet at least two standards:

first, there are dry goods; second, there are many popular books; Second, good writing and readability. In addition to these lucky ones, there are also a large number of books with poor writing skills, as well as a large number of books with poor writing skills. From the point of view of competition, everyone can read best sellers, but if there are dry goods and poor writing, many people will be deterred and difficult to adhere to

this is a great opportunity for you to open up a gap with others. Therefore, when choosing books, just like choosing friends and girlfriends, substance is more important than form. Don't think we are scum just because we are ugly

Rogers has studied the diffusion of innovation all his life, but he has never seriously considered how to accelerate the diffusion of innovation—— Danhua

don't regard readability as the standard of content quality, just as don't regard express delivery speed as the standard of goods quality. Some books, because of the author's problems, are not fluent or difficult to understand. Don't blame them. On the contrary, we should thank them for hiding dry goods so deeply that they drive away many readers

of course, we should also remind ourselves that we should not make such mistakes in our future writing, which will lead to the loss of a large number of readers and the waste of the opportunity to cover more people

there are still two strategies worth mentioning about how to choose books

reading strategy 4: read the same topic batch by batch

the same topic. The focus, style, readability and accuracy of bestsellers, textbooks, practice guides, biographies and history books are not the same. Reading in batches can bomb the brain and give yourself a rich stimulating environment, In this way, the understanding is more comprehensive and three-dimensional. For example, when you want to change jobs, it's useless to go to the other party's official website to read a bunch of introctions. You might as well ask someone inside the company to understand the gossip and lace, and then you can understand them immediately

reading strategy 5: read first-hand literature, do not read "second-hand books"

do not read those chewed things, such as various interpretations, notes, etc., read only the most original first-hand materials. The original literature should always be in the most dominant and important position

after talking about how to choose books, let's talk about how to read

imagine how most people read

many people do not have the habit of marking while reading

most people only remember some vague impressions or core ideas after reading a book

therefore, in view of the common reading problems of these public readers, the corresponding reading strategies are ready to come out: to do the opposite

reading strategy 6: take notes, leave marks, pay attention to output

I may never be able to understand why some people never make marks and notes when they read a book, which is the same as a new book. In fact, leaving marks and thinking in reading has multiple values

first, leave your state, so that you can quickly return to this cognitive state when you open the book next time, instead of starting from scratch. Taking notes is a bit like a dog peeing or taking photos in a scenic spot. If you don't pee or take photos, you can't remember that you've been here. A smell, a look at the photos, wow, all the memories are hooked out: I've been to this place! What happened then?? So, don't worry too much about what you write down in the book, the key is to have a mark to pee

taking notes is a bit like a dog peeing or taking photos in a scenic spot. If you don't pee or take photos, you can't remember that you've been here. A smell, a look at the photos, wow, all the memories are hooked out: I've been to this place—— Danhua

Second, sometimes after reading a Book intermittently, you can read the front and forget the back. Taking notes can help you leave some achievements and feelings at that time, which is similar to the protection of the scene when it is interrupted, so as to facilitate the formation of a line in the future

considering the high time and cost of writing an article after reading, I recommend a tactful way: after reading a book, write 7-10 sentences in the blank space of the first few pages, including the following: main ideas or inspirations, logical structure, how to apply it to work, writing style, whether there are major weaknesses, how to improve the content and form, how to surpass, deepen and perfect, etc. It's up to you to decide what and how much to write

the minimum requirement for taking notes is to remember the main points

reading strategy 7: Strategic attention when reading, strategic contempt after reading

in the process of reading, keep enough humility and learning attitude, after all, you are here to learn. As close as possible to the author, agree or agree

go deep into your cultivation interest

it's a very painful process to go deep into one thing, because it's the most difficult stage for you to start from 0, because you don't understand a lot of things, what is IPS retinal screen? What is resolution? What is SNS? What is lbs? What is e-commerce? Who is Bruce Lee!? At this time, you need to go to the network one by one, and you can also write down them appropriately······ Of course, when we cultivate interest, we usually find that: I don't like this thing as much as I think? What should I do? So I think it's still like the "one" mentioned above: it's really hard to insist on finding a good entry point and letting you do some relatively small interests like archaeology at this time. Fortunately, after visiting some forums and reading some Internet related books, I graally fell in love with this instry. It's like falling in love with something. That feeling can't be explained ~ ~ I'll read it when I'm free and think about it when I'm free

how to combine points of interest and occupation? It's hard to answer this question. If you like to teach and ecate people, you should be a teacher. If you like to save lives and heal the wounded, you should be a doctor. If you like to study, you should continue to study. But in my opinion, many of our post-90s do not want to engage in these traditional instries. Thanks to the progress of the times and science, when every year is the most difficult year for employment, I did not expect that there are so many jobs waiting for us. You like singing, but you can't be a singer. It's OK! You can go to an Internet company as the editor of music player procts, and recommend your favorite music to the audience; You like sports, like watching football and NBA all day, but you can't be a player, it's OK! You can also go to Hupu, sina sports and Tencent sports; If you like shopping and make-up, you can go to Meili Shuo, mushroom street and Jumei superior procts to be recommended by buyers.

tail: I've never done any career planning, but I didn't know until I graated. It turns out that every step I did before seemed to be doing career planning! Therefore, if I can know these earlier and make reasonable "career planning" for my own interests and personality, maybe my university will get rid of confusion as soon as possible< therefore, career planning is very important what career planning is not grounded enough. I dare to redefine it: what do I want to do+ What can I do+ What am I going to do= Career planning

the above is my personal experience. I didn't know what I wanted to do until I was a junior. Then I slowly followed the above step by step. I have a sentence for you: "it's never too late to start now."
