bitcoin is a virtual currency. blockchain is the node to calculate virtual currency transactions. In short, blockchain technology ensures the normal operation of bitcoin system. How to describe the principle of blockchain. That's what the ledger means. I don't know if it's easy to use. It's said that it's quite encouraging. After all, it takes ten minutes to calculate the database account book in this area
but the bitcoin market is unstable recently. Let's have a look. Maybe I'll see you on the roof
2. Key position conflict<
change the key position. However, some keyboards still conflict with each other no matter how to change them. There is no way to change them.
it is recommended not to buy very advanced keyboards. Generally, the more advanced the keyboards are, the more likely they will conflict with each other. Especially, don't buy Microsoft's keyboards, which must be locked
attachment: the following is the information
what is key position conflict
first of all, let's understand what is called key position conflict. Key position conflict is an unavoidable problem of finished keyboard. For a simple example, when we press Ctrl + Alt + Del at the same time in computer operation, the computer only recognizes that it has pressed Ctrl + Alt, but it can not do del. This is called key position conflict. Of course, this problem is impossible. It doesn't matter whether the keyboard in accordance with the windows standard can recognize the combination of other keys. The important thing is that these three combinations must have no key conflict before they can leave the factory. Otherwise, who will want the keyboard that can't be restarted
for key position conflict, we define it as follows: when two or three keys are pressed at the same time in the process of keyboard operation, the keyboard can only correctly recognize the first two keys and has no response to the third or fourth key. However, these problems often exist with the game, and the combination of shortcut keys for windows is unlikely to conflict
generally speaking, there are two kinds of attitudes towards key position conflict. One is not concerned about key position conflict at all, or even does not understand it at all. For example, when he was playing KOF, he found that his opponent could release XX must kill skill through keyboard operation, but he could not complete this action with any skillful operation. It was too late to repent at this time
the other is the super fever fans, who are very obsessed with games. They have been searching for the best game procts without key position conflict, just like the martial arts experts frantically searching for martial arts secrets. Because of their preference, they didn't have a clear understanding of the core problem of key position conflict, so they were confused to find their utopian dream
we all know that the current keyboard technology adopts the non coding film contact structure. This structure is that any key has two layers of film contacts. After we take apart the keyboard, we will find that the number of wires on any layer of film is far less than the number of keys, and each wire connects the contacts of multiple keys at the same time, Any two wires of the upper and lower layers are overlapped on at most one key. That is to say, the upper No. 1 wire may pass through keys 1, 2, 3, 4 and 5 at the same time, while the lower No. 1 wire may pass through keys 1, Q, a and Z at the same time, and the two wires only overlap on key 1
in this way, according to the buttons passed by the upper film and the lower film, A table similar to the following can be arranged:
upper conctor 1
upper conctor 2
upper conctor 3
upper conctor 4
upper conctor 5

there is a table with similar principle in the processing chip of no keyboard, In order to rece the key position conflict, designers are also racking their brains to modify the keyboard circuit arrangement and data table, so that the commonly used games and shortcut keys do not conflict with each other, but this is to rece as much as possible, absolutely not completely eliminate. Now you can understand why there is no conflict when we use hot start Ctrl Alt del? Four direction keys will not conflict, right? People and people are not as good as heaven, there will be some keyboard hit the hole of the game, which leads to the key conflict. Therefore, it is impossible for a keyboard without key position conflict to exist in the current keyboard design. If a manufacturer advertises that his keyboard (so far) has no key position conflict, it would be ridiculous if it is not to return to simplicity
summary:
1. As mentioned in this paragraph, the key position conflict of the keyboard is related to the cleverness of the chip data designed by the designer, that is to say, when the keyboard uses different models and brands of integrated blocks (also known as the CPU of the keyboard), the key position conflict will not be exactly the same
2. It is absolutely impossible that there is no key position conflict for non coding keyboard. The solution can only be game manufacturers, keyboard manufacturers, mutual coordination, try to avoid the emergence of key conflict. So the idea of fans is Utopian
select the keyboard with "no key position conflict"
you must be surprised, why did I say that it is impossible to avoid key position conflict with the current keyboard, and now I say that it is possible to find the keyboard with "no key position conflict"? Isn't that self contradictory? In fact, my statement is relative, but it also helps us to face up to the "key conflict" better, so as to get the essence and reject the dross. Like DIY, fit is the best. Even so, this part will not be the same as the previous keyboard purchase articles (I will see the details later). What I tell you is how to choose a satisfactory keyboard, which will not affect your daily habits and game hobbies
we usually like to shop in the computer city, but we all know that although we can try to buy procts in the computer city on the spot, there are no big problems. But it's not going to let you play games on the spot for testing, is it? Even if you say you buy a keyboard to play games, businesses will think you are strange. What if you happen to run into a business computer without the game you need? Is it installed on site
now I'd like to introce a keyboard testing software, which can not only test whether there are key position conflicts in the keyboard, but also detect the sensitivity of each key in the keyboard. It is a keyboard testing software keycard test proced by passmark software company. The interface of this software is quite simple and intuitive, and the volume is quite small, less than 1m. We don't have to worry about the problem of moving, that is, the disk can accommodate the next. But the only problem is that it's a shareware
the download address is: http://www.passmark.com/ftp/keytest.exe
after opening the software, skip a registration page and the interface of the software will be displayed. When we test the keyboard, we press the key that needs to be tested, no matter how many you press. If the key is reflected, it will turn red. The used key is marked with green, which is the area a in the figure, while the area B in the figure shows the letters reflected by the key you press in the form of text. This software also has a more practical function, is to test the keyboard theory, the average number of typing (half English), that is, the C area of the local pull. Through this software, we can see at a glance what defects the keyboard has< In fact, I didn't want to write this paragraph because I need to offend some domestic manufacturers. Now that we know the keyboard can not be without key conflict. So what is the most suitable keyboard for the public? Because I'm not a God, and not all my keystroke habits are in line with the taste of readers, I'd like to briefly talk about the keyboard with outstanding performance
in my years of playing with the keyboard, I found a very strange problem, which I still can't understand, and summed up a theory. Let me ask you a question first. Let's have a look. Why has the key position conflict been taken out of the table so far? Careful friends may have noticed that this is not only caused by the popularity of FPS games in recent years, but also partly e to the fact that everyone has started to use high-end keyboards (they can't escape SK, BTC, etc., which are proced by several major international keyboard manufacturers). It seems that when everyone used poor quality keyboards before, they didn't care about this problem
after summing up, we can find a very strange law: the more expensive and low-quality procts, the more enjoyable it is to play games. On the contrary, those high keyboards have more or less obvious key position conflicts. The most famous key position conflict is elite. The conflict is puzzling, even the direction keys have conflicts. Maybe it's God playing tricks on people. Since the key position conflict and hand feeling can't completely realize the two rights, we will never bow to the garbage. We need to feel better, but also not affect the overall situation
e to the particularity of this super alternative game we play, our criteria can't be the same as those who think they know keyboard very well, such as Warcraft and CS. I was cheated. I bought a new shell keyboard that Mingji just came out last month. When I went home, I found that all the O2 key settings I could adapt to conflict, Can't play. Because the keyboard itself has no quality problem, so I can only buy a keyboard again! This time, I made full preparations and brought a test software to test the keyboard in the afternoon. About keyboard conflicts, I made the following summary:
USB interface can't be purchased, multimedia keyboard can't be purchased, and a small part of PS / 2 interface can't be purchased
that is to say, as O2Jam players, we'd better consider purchasing PS / 2 interface keyboard and bring our own test software when purchasing, The usage of the test software: open it and press the seven keys that need to be used in the game at the same time. If the software shows that all the seven keys are red, it means that the seven keys do not conflict with each other. It is ideal to play O2Jam on this keyboard. All the keys you have pressed are green, Used to test the keyboard for bad keys. This keyboard test software is called keytest
in addition to this problem, for O2Jam players, I personally think we should pay attention to the selection of keyboards:
1. The keyboard has better elasticity. You can just press it when you buy it.
2. The characters on the keyboard should be laser engraved, otherwise the characters on the keyboard will be blurred soon after being washed by O2Jam, It's better to have a strong concave and convex feeling
3. The shorter the key stroke is, the faster the key reaction time is. For example, the key of X architecture performs better in this aspect. Generally speaking, notebook keyboard uses X architecture
then let's talk about X architecture: from the perspective of key stroke, the average key stroke of desktop key cap is 3.8-4.0 mm, and that of laptop key cap is 2.50-3.0 mm, while & quot; X Architecture & quot; The keyboard keeps the advantages of the desktop key cap, with an average key stroke of 3.5-3.8 mm, which is comfortable to handle. When the tapping force of the top left corner, the top right corner, the bottom left corner, the bottom right corner and the center of the key are tested, it is found that the tapping force of the traditional keyboard is large and uneven, while & quot; X Architecture & quot; The striking power of the keyboard is small and
change the key position. However, some keyboards still conflict with each other no matter how to change them. There is no way to change them.
it is recommended not to buy very advanced keyboards. Generally, the more advanced the keyboards are, the more likely they will conflict with each other. Especially, don't buy Microsoft's keyboards, which must be locked

4. Since the Chinese mainland announced that it would close the bitcoin trading at the end of October, bitcoin prices have experienced a roller coaster market. It once dropped to about 25000 yuan in September, and then rose to nearly 40000 yuan in October, which seems to show its tenacious vitality< However, this high price is very fragile
Chinese mainland bitcoin game player has been transferred to Hongkong after a lot of closes. The exchange can be used as futures by some exchanges, which is about 10-20 times of leverage. Combined with the over-the-counter trading, even after the "outbreak", the trading volume is only 1 / 100 of the previous on-the-spot trading volume. It can be seen that the number of players participating in bitcoin trading has been greatly reced, and a few speculators have managed to maintain the bitcoin price with the help of leverage< However, it is hard to imagine that these speculators are totally supported by free funds. Considering the borrowing cost of funds, the fact that the world has entered a cycle of monetary tightening, and the increasing attention paid by more and more countries to the risk of speculating in digital assets, regulatory policies will become more and more intensive. I am afraid that this kind of high price without foundation will not last for too long. Could it be that a few early hoarders deliberately made the game in order to find the receiver? It's not impossible
on the other hand, the official digital currency is also under intensive preparation. In fact, since the second half of 2016, there has been more and more discussion on official legal digital currency in China. In September 2017, China Banknote Printing and Minting Corporation also set up a blockchain Research Institute to track and study digital currency technology, which is generally regarded as a precursor for the Chinese government to accelerate the research and launch of digital currency. China is likely to be the first country to issue official legal digital currency
of course, this process will not be achieved overnight, and the final proct will be quite different from digital assets such as bitcoin, which is more like a digital legal currency based on cryptography. Now the suspense is whether the settlement mode of this new legal digital currency is real-time Centralized Settlement similar to the current online banking mode, or offline point-to-point settlement. If it is the latter, the application prospect will be broader, and the use may be more comprehensive
in the final analysis, money is the medium of transaction and the means of storing wealth, and its essence is the embodiment of credit. Therefore, in order to play the role of money in a long period of time, this medium must have considerable credit. At present and in the foreseeable future, the strongest credit still comes from the powerful means of the government. If someone takes out the golden yuan certificate in the period of the Republic of China, it can only be called antique
therefore, in the long run, I am not optimistic about privately issued currencies. In particular, bitcoin has a logic defect in the underlying design that is difficult to last. So now we see the phenomenon of "capacity expansion", and every time this "correction" is harmful to its credit
however, even if bitcoin and other private digital currencies can not become the mainstream, blockchain technology has great potential. For example, digital property certification. We can imagine that in the rental market, if the law forces the landlord or intermediary to show the ownership certificate of the house with official or third-party certification and based on blockchain technology before renting the house, then the problem of fake houses will be much less
on this basis, it can also make remote online mortgage and transaction possible. The digitization of assets will make the transaction more convenient, which can be applied in many fields, and even for direct international transactions, such as long-distance mortgage and transaction of bulk commodities, futures and valuables (real estate, jewelry, antiques, art, etc.)
of course, all these also need supporting laws. Only when there are clear precedents, can it play a role in the future property rights protection based on blockchain and build up public confidence in it“ "From zero to one" will be very slow, but once it breaks through the critical value, with the first person to eat crabs, then "from one to ten thousand" will be completed quickly
in addition, cooperation between countries is also indispensable to expand the scope of application. Digital technology is inherently easy to spread across regions and international. When the new technology has accumulated and pieced together the required jigsaw puzzle, the breakthrough from quantity to quality is only the last layer of window paper. The breakthrough is inevitable. The chance is just who will finish it. Everyone is running like crazy, but history will only remember the first one who crossed the finish line
as a new thing, the application scope and depth of blockchain still need to be explored, just as at the beginning of the birth of electric power, people don't know its use. However, with the integration of human behavior with Internet and digital technology becoming more and more in-depth, the prospect of cryptography technology similar to blockchain must be unlimited.

6. 2 Arbitrage trading: that is to buy a futures contract and sell another different futures contract at the same time. The futures contract here can be different delivery months of the same futures variety. It can also be two different commodities related to each other. It can also be the same commodity in different futures markets. Arbitrage traders make long on one futures contract and short on another futures contract at the same time. They make profits by changing the price difference between the two contracts, which has little to do with the absolute price level< Compared with the usual speculative trading, arbitrage trading has the following characteristics:
1. Lower risk. The price difference of different futures contracts is far less dramatic than the absolute price level, which reces the risk accordingly, especially avoids the risk of sudden events on the disk
2. Arbitrage trading can attract large funds, because of bilateral positions, it is difficult for major institutions to force arbitrage traders out< 3. Long term stable yield. At the same time, arbitrage is operated by using the unreasonable price difference in the market. In most cases, the unreasonable spread will return to normal soon, so arbitrage has a high success rate
there are three main arbitrage modes: intertemporal arbitrage, cross commodity arbitrage and cross market arbitrage< 1. Intertemporal Arbitrage: it is an arbitrage mode in which futures contracts of the same commodity in the same market in different maturity months are traded, and profits are made by using the price difference changes of contracts in different maturity months. This time we provide you with arbitrage of soybean and natural rubber varieties
2. Cross variety Arbitrage: it is to use the price changes between two different but interrelated commodities to hedge for profit. That is to say, when one month futures contract of a certain commodity is purchased, another similar delivery month futures contract of related commodities is sold at the same time. There are mainly (1): arbitrage between related commodities (this time we provide arbitrage between copper and aluminum) 2 Arbitrage between raw materials and finished procts (such as the arbitrage between soybean and soybean meal)
3. Cross market arbitrage: it is a way of buying (selling) a commodity futures contract in one month in one futures market and selling (buying) the same kind of contract in another market in order to hedge profit taking at a favorable time. This time, we provide the most mature arbitrage between Shanghai copper and London copper and the arbitrage between Dalian soybean and CBOT soybean
arbitrage transaction can be divided into real arbitrage and virtual arbitrage according to whether the physical object is handed over or not. Arbitrage generally try not to take firm offer, through the price difference changes of different contracts to profit. With the rich practical trading experience and the intervention of large funds, many enterprises begin to combine futures and spot, further develop the hedging theory, and raise the goal of hedging to value-added with a more positive attitude. In this way, arbitrage is more and more difficult

7. 1、 Offline channels
offline channels can be divided into a variety of sub channels: pet store, pet hospital, large supermarket (Suguo, Wal Mart, Carrefour, etc.), cat house, dog house, of course, in addition to the above, there are some other private channels
1. Pet shops are uneven, so it is not easy to make a unified description here. However, most of the regular pet food has gone through several levels of agents when they go to the pet store, and each level of agent needs certain profit support, so the price of food in the pet store will be relatively high; However, since it is a pet store, the brand richness in the store will be relatively high, and besides pet food, there will be pet procts for your daily needs
2. Pet hospital
compared with pet shop, because of the different business focus, pet food in pet hospital will be relatively less variety, the price will not be too different from pet shop, and the price in hospital will be a little more expensive; However, there will be more functional food (or food with medical effect) in pet hospitals (after all, it is related to the main business)
3. Large supermarkets
at present, domestic supermarkets do not pay enough attention to pet food. In the first tier key cities, there will be a little more pet food and supplies in supermarkets. In many other cities, the category of pet food may not be displayed in supermarkets; Take Nanjing as an example. When I took my children to the supermarket yesterday, I paid special attention to Suguo supermarket. There is only Baolu brand, which is displayed in a corner; The price as like as two peas, which are exactly the same price, may be the reason why the brand price is controlled.
4. Cat house and dog house
generally small cat house and dog house seldom provide pet food, but they will get pet food through channels, and the price is lower than that on the market; Of course, in addition to the finished food, they also have channels to get the daily non-finished food for pets, such as meat and ribs. Most of them have very low channel sources
5. Other
this is relatively few, sometimes some agents will do it; In general, they seldom go to foreign promotion, only for friends, relatives and other familiar people
Second, online channels
let's first give you a type of popular websites. From the business model, there are BTB, BTC, btbtbtc, etc. BTB refers to enterprise to enterprise, and the typical one is Alibaba; BTC enterprises should have few pure BTC websites for consumers. The self operated procts of Jingdong and Suning can be listed as BTC mode; Btbtc is relatively common. The open platforms of tmall, JD and Suning are all btbtc mode; In terms of commodity classification, there are comprehensive categories and vertical categories. Comprehensive categories are just like tmall and Jingdong. The commodities sold on the website are all categories; Vertical category refers to the sale of a certain category of related goods, such as e-pet, the earliest Dangdang (now it is a comprehensive category, because it is not only a website selling books), etc;

8. CPU:
Intel CPU -- Intel has many proction bases in the world, among which Malaysia and the Philippines are the two largest OEM bases. In other words, most of the CPUs proced in these two places are supplied to OEM manufacturers; Costa Rica, on the other hand, has a small number of factories that proce original CPUs, mainly for the retail market. As we all know, Intel's OEM CPU accounts for a large proportion of its total output, which is definitely more than the supply of the retail market. Therefore, it gives people a feeling that the CPU proced in Costa Rica is very few. In addition, the vast majority of Intel CPU sold in China is imported from OEM channels, so the original box packaging is even more rare. Japan's Sanyo makes fans for Intel's boxed CPU. AMD CPU -- Taiwan Lianhua electronics and AMD announced that they will cooperate to develop semiconctor chip manufacturing process, and Lianhua Electronics will use manufacturing process below 0.13 micron to proce CPU for AMD. In addition, they will jointly build a 12 inch wafer factory with Singapore, which will proce CPU and other logic chips in the future< (2) graphics cards:
the low end of Mingxuan, Yingtong, Onda, Qicaihong and Shuangmin Minimovie: they are OEM by Shenzhen's Palit, with average quality, but large market sales volume
the middle and high end of Mingxuan, Yingtong, Onda, Qicaihong and Shuangmin Minimovie: ATI's are OEM by lanbao or Powercolor, NVIDIA's are OEM by Chengqi, Shuangmin and Qingyun foundry's
Gengsheng are one of the few independent development, design and manufacturing graphics card manufacturers in the market. Their graphics cards are famous for their functions, practicality and price, which are rare<
Dylan Hengjin - made by Taiwan's Chun Xun
Spartak - made by jabber
Songjing - made by elites
Shuangjie - made by Qingyun
xintianxia - slightly higher graphics cards are made by Chengqi, others are all made by the underground workshop of Bao'an in Shenzhen
Elsa - the earliest Elsa's absolute original factory, Because it develops, designs and proces this kind of non-public graphics card. Later, with the rapid development of NVIDIA, Elsa, which is famous for procing non-public version, did not have enough time to develop new plate base, so it is normal for Elsa to find someone to do OEM. MSI doesn't directly work for Elsa. I heard that MSI is a public OEM of NVIDIA. If you observe carefully, you will find that there are many similar cards like this. MSI makes the public version, while Elsa uses the public version. Similarly, for example, Onda always says that Elsa is responsible for the proction of new cards. After careful comparison, it's really the same. There are only slight differences (for example, the BIOS version and capacitor type are different), But I don't know who did it for whom. Elsa used to be different because it was the first to develop and use non-public version of NVIDIA. For a long time, part of NVIDIA's cards (Quadro Series) were driven by ELSA, but now it is also using public version. A while ago, it was very popular on the Internet that Elsa filed for bankruptcy, The general content is "Elsa has been unable to bear the high cost of development, if it can not find a suitable source of investment, it is ready to file for bankruptcy" and so on. Fortunately, it's still alive now, but now the Quadro series has been licensed to Rita (the Quadro series used to be exclusively licensed by ELSA). The graphics card part of Elsa in Germany is OEM by MSI and Jijia
MSI is the largest OEM manufacturer of NVIDIA, and Rita is the most important partner of NVIDIA in Asia Pacific. This year, it began to provide its professional graphics chip. You know, it was only provided to Elsa before
Gigabyte is also a large OEM of graphics card, but its cooperation with Matrox in the proction of g400 graphics card was a failure, so I won't say more
ATI original graphics card - the manufacturing process and materials are excellent, but it is said to withdraw from the Chinese mainland market to encourage the third party manufacturing plant. Oh, in the future, there will be less and less good things that you can buy. I'd better support Gengsheng. ha-ha. ATI series is partly manufactured by Zhenxun<
innovation --- looking for MSI OEM NVIDIA series has been almost a year and a half
TSMC OEM nvida's GPU
Korean graphics card --- no matter the workmanship or design is absolutely first-class, such as Suma, but it is rare in China

Yingtong: most of its procts are OEM by Xiangsheng factory, and some are OEM by Youtong (DFI) or Chengqi.
Onda: there are many OEM manufacturers, which are very chaotic. Recently, it is mainly Youtong (DFI) and Jiebo, and the quality is OK, But rarely update the driver and BIOS
via's original motherboard: all of them are manufactured by shuotake, and the workmanship is excellent. Now there are few
three emperors, pcchip, Hongchuan, Jinying, Huaxin, Huaji, Huahong: all of them are made by elites.
upgrading: some of the low-end motherboards are made by elites, In order to alleviate the problem of insufficient proction capacity in Suzhou on the mainland, Shuangjie: the whole line is OEM by Qingyun, and there is an unconfirmed relationship between Shuangjie and Qingyun.
Pan Ying and Benz: except for the procts of DFI when they were just launched, most of them are proced in Baoan card street in Shenzhen, The quality is very poor

Some of Dell's liquid crystal displays are also BenQ, the heart language series of moto mobile phones are OEM, and T189 is OEM<
BenQ's LCD or Youda optoelectronics's OEM
Neso --- is made by Dongguan Jingcheng,

the main manufacturers of CRT display are Samsung, Huaguan (MEG), HENGGUAN (EMC), AOC, LG, Changcheng (synonymous with junk goods), BenQ (cost can't support), etc Sincere and prosperous. Other manufacturers are going to collapse. Xiahua is expected to be over in March next year. TCL trump card will be over in the last three months. Delta is going to shut down its monitor proction line soon, and so on. There are many brands of monitors in other markets. Except for the brands listed above, I can basically ignore them, such as dreamer, buffalo, Neso, etc. these brands are still in today's market, and I don't know where they are tomorrow. AOC does OEM for many large manufacturers, but there are still differences in quality. It seems that the best quality is given to big international manufacturers such as IBM and HP, followed by Lenovo and founder, and then their own brands. From good to bad, they are AOC, envisionion, Topview and so on, and even have no labels, It's very cheap to get some low-end displays in the factory, for example, the 17 inch flat screen may only cost 600 yuan.
