Public money mining
It's a scam. Many Internet enterprises and network security enterprises believe that illegal "mining" has become a serious network security problem
with the rise of "cloud mining", the virtual machine has become the main use object of digital currency such as Monroe coin and Eli coin, and the situation of embezzling cloud computing resources for "mining" has also increased significantly; Security team monitoring found that "competing for mining machine" has become one of the important purposes of Botnet expansion; And found a new type of "mining" virus (mining XmR / Monroe), the virus spread wildly in two months, illegal "mining" profits of nearly one million yuan
extended information:
from a commercial point of view, the business model of mining can walk out of a "healthy road". As long as the "incentive money" is lower than the average cost of new users in the market, the business model will be reasonable and feasible
however, if the platform tempts users to participate with "no capital, no profit", it is worth being vigilant. The so-called "mining" opportunity provided by the platform is likely to be "digging a good hole" waiting for you to jump in
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
secure payment. Qwc has no pre excavation and ICO, and adopts cryptonight algorithm (supporting mainstream mining machine X3 and A8 +) POW mining.
and fruit powder also use a sentence "buy before proctivity, buy 271" to make complaints about iPad.
I personally experienced traveling to Japan at that time, but I couldn't put it down in our media. I wanted to send a few words in a simple code, but it was too heavy to carry a notebook. The iPad was light enough to open and process easily. With a Bluetooth keyboard, it was really enough to deal with document processing, but it was hard to send. There was no mouse or cursor, I think the iPad Pro is only "able to do" in terms of document and release, but there is still a gap of about two surfaces away from "doing well". Finally, I chose to take the surface to travel. After all, it's no problem to buy an old surface pro at this price. With simple image and text processing, the complete win experience of surface is much more comfortable than playing tricks on IOS
in terms of proctivity, I think the real proctivity that iPad Pro can do is that it has obvious advantages over other devices. The first is drawing, the second is the later stage of drawing repair. The additional usb-c socket is not for you to plug in a USB flash disk, but for connecting a digital camera. IPad Pro should be an artifact for painting masters and image workers. When you go out to take photos, you can immediately receive the effect of viewing raw images from iPad pro, and you can use Lightroom to repair pictures later. The touch experience is no worse than that of the mouse. Compared with surface, iPad Pro can be more like a tablet than win10's tablet mode, obtaining a more relaxed and convenient operation experience, and it is lighter and thinner It's easier to carry, especially in the small 11 inch version. And the color standard of iPad Pro is close to that of professional LCD screen, which is very friendly for photographers and even photographers
in terms of drawing, although the advantages of software are certainly not as good as some professional drawing software of win10, some professional drawing software on IOS is enough to draw commercial images. As an amateur, I used to use digital board, then surface, and now I use iPad. Personally, I still think the experience of iPad Pro is the best, Especially the pen of Apple pencil II, the experience is great
at the moment of the release of IOS 13.1, Apple also installed a new system, the iPad OS. This time, the iPad OS has updated many functions, including some gesture operations, which make ing and pasting, which are more related to "proctivity", faster and more convenient. Most importantly, this time, the iPad starts to support USB flash drives
after the author inserts the ordinary 128G usb-c USB disk of Sandi into the iPad pro, the iPad Pro can actually read the contents of the USB disk from the "file" menu, including pictures, videos, audio and text documents, and can realize basic , paste and other operations by long pressing, And you can all kinds of articles in iPad pro to this USB flash drive in the way of "" and "paste". It should be noted that the author tested that apple can only recognize the disk format of exFAT, but it cannot recognize the U disk of NTFS
in the past, the iPhone can insert a dedicated USB flash disk through the specified hardware, and read and write the USB flash disk through a third-party app, but this time the iPad can use an ordinary USB flash disk, which is closer to the "proctivity tool". The high-capacity USB flash drive can easily and quickly import video and picture materials into the iPad. After creation, it can also easily export them. In addition, some updated gestures are used to complete the and paste operation of text editing. Apple's goal of truly regarding the iPad as proctivity is very clear, although it has not been able to operate proctivity as smoothly as Mac OS, However, we can feel from this update that the boundary between iPad and MacBook is becoming blurred. In the future, we may connect the Bluetooth keyboard and mouse, plug in the USB flash disk, and use some full-featured apps to really create like Mac. Then, the 6500 yuan super expensive iPad Pro can not become a vase of entertainment with its computing power.
