2. Draw multiple cubes, arrange them in order, name them, and remove the meshender attribute (no rendering), which is equivalent to drawing a grid, which is easy to understand
3. It's troublesome to judge the range with two-dimensional array (mainly integer), The simple way is that the computer obtains the original coordinates of the model (such as the center point of the model). When the absolute value of the x value (and y value) of the mouse's real-time coordinates minus the original coordinates is equal to the side length of the square, the square (or other dry points) will be displayed with the real-time coordinates as the center, The real-time coordinates are used as the original coordinates for the next step
in fact, this is not the first time for M1 processor to mine. As early as last December, xmrig developers began to use M1 Mac to mine Monroe coins. However, the mining efficiency of M1 MacBook Air is very low. According to Gu Yifan's test, the mining efficiency of Ethereum is only 2mh / s, and the power consumption is 17-20w. Compared with NVIDIA graphics card, the average daily income is only US $0.14<

this u is the most high-end u carried on human spacecraft so far
in terms of processing power, such a guy can't compare with any personal PC, that is, your home computer, but the power consumption is only 5W, and he can work at minus 55 to 125 degrees. It's not easy. The temperature in space changes from minus 200 degrees to above 200 degrees very quickly. It's very safe to have such a high limit CPU
the successful launch of the "tianwen-1" Mars probe, the completion of the beidou-3 global navigation satellite system, the launch of the long march-2 launch vehicle, the successful launch of the lunar exploration project chang'e-5 probe, and the opening of the Lianhuai Yangzhen railway Beidou-3 global satellite navigation system is composed of 30 satellites, including 24 mid circle earth orbit satellites, 3 geostationary orbit satellites and 3 inclined geosynchronous orbit satellites
beidou-3 satellite navigation system provides two service modes, namely open service and authorized service. The open service is to provide free positioning, speed measurement and time service in the service area. The positioning accuracy is 10m, the time service accuracy is 50ns, and the speed measurement accuracy is 0.2m/s
authorization service is to provide more secure positioning, speed measurement, timing and communication services as well as system integrity information to authorized users
on June 23, 2020, the last global networking satellite of beidou-3 was launched at Xichang Satellite Launch Center. On the morning of July 31, the completion and opening ceremony of beidou-3 global satellite navigation system was held in Beijing
On August 6, 2020, China successfully launched gaofen-9-04 satellite into orbit with the long march-2-d carrier rocket at Jiuquan Satellite Launch Center At 4:30 on November 24, 2020, China successfully launched the chang'e-5 probe of the lunar exploration project with the long March-5 remote-5 carrier rocket at the Wenchang space launch site of China. After about 2200 seconds of flight, Shunli put the probe into the predetermined orbit and started the first sampling return journey of extraterrestrial objects in China Lianhuaiyang Town Railway is a high-speed railway connecting Lianyungang City to Zhenjiang City in Jiangsu Province, is a north-south high-speed railway in Jiangsu Province, is an important channel through southern, central and Northern Jiangsu, is an important part of the central and Northern Jiangsu railway networkon December 11, 2020, the huaidan section of Lianzhen high-speed railway (from Huaian east station to Dantu station) was completed and opened to traffic, marking that the whole line of Lianzhen high-speed railway was completed and opened to traffic
Due to the complex and harsh space environment, in order to improve the reliability of the chip, the density of the computing units on the chip will be controlled very low, resulting in the relatively poor computing power, but at the same time, the reliability will become extremely high, not as simple as the x86. Therefore, the software carried by the satellite should still strictly control the amount of calculation to avoid unnecessary calculation. Space class chips remain the focus of the US and EU embargo on China

mechanical energy is the sum of kinetic energy and potential energy
kinetic energy and potential energy can be transformed into each other
as long as we know its kinetic energy change, we can calculate the work done by gravity.
F = [g (M earth) (M satellite)] / (R radius of motion) ^ 2
