2. Minerhub's wondermole system is a "diskless" mining system based on Linux kernel, which is deeply customized for miners' friends

solve the problem in an all-round way

1. Miracle Moore's Linux kernel has been deeply optimized for more than 200 times to avoid the problem that some hardware failures will directly lead to system crash
2. In view of the situation that many mining software in the market can't connect to the mining pool after restart, miracle Moore perfectly solves the problem by using the function of resetting the image after each restart of the mining machine
3. After testing, the average computing power error and delay share of miracle Moore system in each mine pool are not more than 1.5%, which significantly improves the mining revenue of users
4. After numerous experiments, miracle Moore development team has obtained the optimized VBIOS overclocking setting of graphics card. Compared with the traditional overclocking method, it can further improve the computing power of graphics card by 5% and rece the power consumption by 15%!

3. Ethereum blockchain has exposed three major problems, and its founder vitalik buterin has been unable to interpret them for a long time. The first is the low performance and TPS of Ethereum blockchain as a whole; The second is that resources are not isolated. The event of cryptokitties virtual cat once occupied 20% of the traffic of the whole Ethereum, which directly caused Ethereum network users unable to carry out timely transactions, which is the biggest pain point of resources not isolated; The third problem lies in the embodiment of Ethereum's governance structure. As a decentralized distributed ledger, the founder team of Ethereum has dominated its network development in the past. The over centralized governance mode has led to the bifurcation of eth, etc and ETF in Ethereum, and the Ethereum community is now in a state of fragmented governance. In the view of Ma Haobo, founder and CEO of "aelf", all kinds of disadvantages of Ethereum are unacceptable. Therefore, the positioning of "aelf" is born for the next generation of decentralized underlying computing platform of Ethereum, which focuses on solving the problems of insufficient performance, non isolation of resources and governance structure of Ethereum.

4. At the top of Ethereum is DAPP. It exchanges with the smart contract layer through Web3. JS. All smart contracts run on EVM (Ethereum virtual machine) and use RPC calls. Below EVM and RPC are the four core contents of Ethereum, including: blockchain, consensus algorithm, mining and network layer. Except DAPP, all other parts are in the Ethereum client. The most popular Ethereum client is geth (go Ethereum)

5. With bitpie wallet, this is the largest bitcoin wallet in China. It can buy and sell bitcoin with one click, which is much more convenient than the exchange.

6. Of course, it's worth investing. Ethereum has broken a new high for the second time. It's up to $1414, but we don't recommend catching up. Can go to the currency to play spot, currency spot trading, safe and stable, not burst. Suitable for ordinary investors.

7. Eth0 to eth3 are the interface numbering methods of some devices that have not used AMTT. They are not necessarily related to LAN port and WAN port. This numbering method is the default interface name of Linux. The naming here is similar to that of some devices identifying network port 1, network port 2, network port 3 and network port 4. This kind of device has no clear LAN port and WAN port, which interface is connected to external network and internal network according to your configuration mode. So your question is basically answered. As for whether this device is a router, you don't specify the model, and I can't check it. I can't answer that. I recommend that you can check it on the Internet according to its model. You can usually check its user manual and see it.

8. From this passage: Xiaohong is very beautiful and has good grades. The head teacher likes her very much and always acts on her. Sometimes after the end of self-study in the evening, she still stays to discuss learning problems, but Xiaohong does not exclude the behavior of the head teacher. In addition to Xiaoming, the whole class hated her very much and often bullied her. Everyone scolded her for pretending to be arrogant and being coquettish behind her back. She always liked to report to the teacher and seced the head teacher. Xiao Ming is an exception. He has been fond of Xiao Hong for more than two years. He gives her food every day and helps her organize the books thrown away by her classmates. And Xiaohong is not moved by the things he gives and the care he gives. But Xiaoming still likes her, and insists on giving her things and calling her, even if she answers the phone and hangs up immediately. One day, Xiaohong was killed in the classroom. The killer tied her to her seat with a rope. Her face was covered with layers of wet tissue, and she died of suffocation. Little red's hair was messy. When she opened the tissue, she found that her face was bruised and her clothes were torn to pieces, but she was not indecent. The time of death was about 11 o'clock the night before, and a lot of snacks and supplies were found at the scene. All the students in the class agreed that they were all given by Xiao Ming. JC also found her mobile phone in her pocket, opened it and checked the call records. It was found that Xiaoming had called Xiaohong at 11 o'clock the night before, and the call time was 2 seconds. The school security office said that they went to bed very early last night and didn't check the classroom. About 30 surveillance cameras around the school were crooked and covered with black cloth in a short time. Ma Jian, the head teacher, also said that he went home to bed very early last night. Xiao Ming is in agony about Xiao Hong's death. This has caused a huge shadow to Xiaoming. Xiaoming is going to dig a big pit to bury Xiaohong. Here's our problem!!!! Which school is the best?

9. I just forgot that rx460 was beaten by gtx1050. It was more expensive than gtx1050 when it first came out. Its performance was only better than gtx660. Then it came out with 1024sp full version 460.
