the bottom of the parallelogram is 2m = 20m
the area of the parallelogram is 6m × 20 = 120 (square decimeter)
triangle area: 2 × two ÷ 2 = 2 (square decimeter)
can be cut to 120 at most ÷ 2 = 60
However, it is not enough to have these professional abilities. Xiao Wei thinks that he needs another "three conditions"
First, your language must be C + + or go; Second, I know something about distributed computing, cryptography and P2P network programming; Third, we hope you have an understanding of the principles of economics. "why should there be economic principles
"because in addition to technology, bitcoin also has a problem of economic game theory." Xiao Wei said that by constantly raising the cost of doing evil and increasing the reward of workload, we can restrain evil and encourage good through economics
This is probably a classic case in game theory"therefore, blockchain network design, in addition to technology, also understand the principles of economics, we call it ecological construction." Xiao Wei said
03 belief in blockchain
"just as you can't ask the existence of Christian God, it's hard to answer why you believe in blockchain." Xiao Wei said, "my understanding of faith is that when you encounter setbacks and challenges, you firmly believe that you can overcome them."
especially in the budding stage of blockchain, technology exploration will encounter many challenges, "resource, landing, technical and regulatory difficulties, but as long as you firmly believe that" this is good ", you can persist." Xiao Wei said
Xiao Wei firmly believes that blockchain technology is helpful to the future society
he has several judgments
first, blockchain technology will not fade out immediately. It has a "golden decade" and a "silver decade"
"2018-2028 is a good opportunity for the blockchain instry." Xiao Wei believes that, like the Internet in 2000 and the mobile era in 2008, there may be a golden period of vigorous development: the improvement of talent level and company market value
"so our advice is, if you miss mobile and AI, don't miss blockchain." Xiao Wei will suggest programmers to do blockchain, "my positioning for the current team is that after three years, the minimum annual salary can reach one million."
two is, at present, there is a serious bubble in the block chain area, just like the Internet of the year. p>
in 1999, there was a very strange phenomenon, that is, changing the domain name of the company. As long as the domain name of the company is changed to ". Com" or "* *" online ", the stock price will rise
this wave of renaming has also been perfectly copied into the field of blockchain. A-share listed companies have set up "blockchain laboratories" one after another, and the stock price has risen; Long island iced tea, an American soft drink company, announced its name change to long blockchain, and its share price soared by 500%
therefore, there is a certain bubble in the block chain instry, which is also understandable. p> Thirdly, blockchain technology and Internet technology are equivalent
what will be the relationship between blockchain and Internet
"the Internet is a way to obtain information, and blockchain is a way to value trust." Xiao Wei believes that the biggest change in blockchain is the improvement of efficiency
this efficiency is not technical performance, but enterprise efficiency
for example, in the past, there were so many intermediate links in point-to-point consumption because the two sides could not trust each other, with the purpose of "increasing trust"
If peer-to-peer can trust directly, the whole business model will change dramatically
"the biggest change of blockchain is to solve the problem of trust, make your trust become particularly simple, and the whole intermediate link is constantly compressed." Xiao Wei thinks
and the subversive power of blockchain is born with this
on the one hand, blockchain improves efficiency and promotes the reform of the whole instry
for the whole enterprise, speed up is very important. It may take ten days to standardize a line of business project before, but with the addition of blockchain, the time for trust, communication and cooperation is greatly reced
Xiao Wei cited the example of High-speed Railway: the speed of high-speed railway increased from 80km / h to 300km / h, Zhejiang Province began to establish "one hour economic circle", and "if it is faster, it can even affect the house price, isn't it subversion?"
on the other hand, in the new business ecology under the blockchain, the impact of brand will be very big
"a brand is an endorsement of quality to a large extent," Xiao Wei said. "The emergence of blockchain can be achieved, and removing the brand can still guarantee the quality."
This is also the core competitiveness of new retail and new manufacturingfor example, when we buy a certain brand of gold jewelry, what we value is actually the process behind the brand. If we can directly establish "trust" with the gold shop and craftsman behind the brand, we no longer need this brand as an endorsement
"after the whole trust is changed, the whole proction relationship is changed." Xiao Wei thinks
"Marx said that proctive forces determine relations of proction, but now that proctive forces are rich, what we need more is not the improvement of proctive forces, but the redistribution of relations of proction." Xiao Wei believes that "only when the ceiling of relations of proction is" arched upward ", will proctivity continue to move forward."
"the redistribution of resources brought about by every change in proction relations is an opportunity to create wealth. There will be people rising and people falling." Xiao Wei said that this is also the fundamental reason why the coin circle is so crazy
However, Xiao Wei does not think that blockchain can replace the "classical Internet""classical music is not necessarily worse than modern music. It is the same with classical music and classical economics. In many technical fields, classicism, modernism and postmodernism are juxtaposed
"the word" classical Internet "appears because many people in the blockchain circle do not understand what blockchain is and why blockchain can change the world." Xiao Wei thinks
as a centralized "giant", will the network be subverted by blockchain
Xiao Wei believes that the Internet will not be subverted
"search is not the same as business, nor is it the same as brand. The most important thing of search is easy to use, and it doesn't need brand to make credit endorsement."
"network is the least likely to be subverted by blockchain in batj." Xiao Wei said
Kwai tiktok is a fast track record of life platform with short video.
Kwai tiktok: the center of the upper bound is larger, while the upper part of the upper bound is larger, while the jitter is centralization, and the group is more concentrated. Kwai Kwai tiktok: br / > different characteristics: fast men and women are proportionate, while the shaking is mostly female users
different operations: no matter who has the limitation of the fast track, no one can shoot. And the requirement of shaking is relatively high, usually based on tiktok and music, and also the use of filters and lenses.
but you can try both and choose the one that suits your operation.
