Building Ethereum under Ubuntu
1.下载安装包：ethtool-3.15.tar.gz，将其放入自己的路径下，解压：tarzxvfethtool-3.15.tar.gz
2.编译安装：
cdethtool-3.15
sudo./configure
sudomake
sudomakeinstall
3.ethtool-sethX[speed10|100|1000]//设置网口速率10/100/1000M
[plexhalf|full]//设置网口半/全双工
[autonegon|off]//设置网口是否自协商
例如：ethtool-
I don't understand your purpose
eth0 is the device name. Eh0 is connected to an Ethernet network
if you mean you can't connect to the Internet
it depends on the network condition of your home
if you want to use PPOE, you can click on the link to change the configuration of the linked device, and you need to enter the password you set at the time of installation. Then add PPOE
sudo make
sudo make install
/ etc / network / interfaces
sudo VI / etc / network / interfaces
you can edit it and replace the line about eth0 with the following line:
? The primary network interface - use DHCP to find our address
auto eth0
Iface eth0 INET DHCP
use the following command to make the network settings effective:
sudo / etc / in It.d/networking restart
you can also directly enter the following command from the command line to get the address
1ntr = 1.6711 RMB
1ntr = 0.5984 RMB
“ Online delivery & quot; With low threshold, time freedom and other factors, it has become a career choice for many people; I'll be a rider in the future;, It's also popular among college students. It's worth noting that online delivery workers are not only the best choice for their careers, but also the second choice for many people. In fact, the takeout platform is a commercial company. Don't think much about this kind of platform. The distribution of takeout platform is not as simple as you think. From a general view, the rules for businesses, Basically, it keeps changing year by year. Basically, it is to increase the cost of the platform, from the initial 7% to the present 23%, which makes the businesses feel helpless. Perhaps, in the face of higher and higher delivery fees, unmanned delivery is a good choice
an expert from the Academy of Social Sciences once said that there are three obvious characteristics of takeout work, namely, labor-intensive, scattered working hours, and strong algorithm intermediary. Similar to construction workers, workshop workers, and garment processing workers, takeout work is more efficient; Fashion & quot;, But it still can't escape the curse of labor-intensive work, that is, long labor time, high density and high pressure. The whole work process of takeout brother is also subject to the strict background algorithm; Discipline & quot
careful users will find that there is a small number on the arm of some takeaway operators. This number function is similar to a GPS, which can connect the corresponding delivery personnel with the intelligent logistics scheling system. It can not only monitor the delivery route and geographical position of the delivery personnel at any time, but also prompt them when they deviate from the track. Therefore, it management of the delivery personnel is realized, Generally speaking, artificial intelligence is a branch of computer science, which is used to study the laws of human intelligent activities.
it is equivalent to using the basic theories, methods and technologies of computer software and hardware to simulate some intelligent behaviors of human beings to construct an artificial system with certain intelligence, so that the computer can liberate the hard work of human beings. The main research fields include robots, robots, computers, etc Machine learning, computer vision, image recognition, natural language processing and expert system, artificial intelligence has experienced three upsurges since it was officially named at the Dartmouth academic conference in 1956. Now we see that as the world moves towards the digital era, the digital technology represented by cloud computing, big data, artificial intelligence and blockchain has brought great benefits to the society Economy and indivials have brought revolutionary changes,
but all digital and intelligent technologies are aimed at making machines learn, think and express in the way of human beings, and assisting human beings to make work, study and life more simple, convenient and efficient. So what is the logic behind the intelligent distribution system? Is the algorithm forcing takeaway riders to run at high speed against the risk of speeding? What is the relationship between algorithm world and human
In order to make the future optimization more accurate, once the delivery time of the rider becomes faster, the system will judge that the time required for this journey can be shortened. In the future, the system may adjust the expected delivery time, but it depends on the optimization goal in the delivery, that is to say, such an algorithm is not intended to be anti human. Objectively, whether it is 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 minutes, 5 The 10 minute small button or the 8-minute flexible time are both expedient measures, rather than drastic measures. Even if the requirement of long delivery time goes back to the pre liberation one night, this phenomenon can hardly be eliminated. After all, the takeout boy himself has the demand to receive more orders and make more moneyin grub_ CMDLINE_ Add the parameter net.ifnames = 0 biosdevname = 0 to "Linux", as shown in the figure below
# update grub
if you are prompted that there is no such command, please first enter the installation command
# apt get install Grub2 common
# VIM / etc / network / interfaces
change "EM ^ ^ ^ ^ ^ ^ *" to "eth0"
