720 computing power

1. How many cycles does the computing power of the mine help the proct? Is the rent refundable? This is not very good.

2. 91 / 90 is the load factor. You can check how many kilos it is. T is the speed level.

3. Apple's serial number does not contain the letter O, only the number 0. After modification, the serial number you provided is still invalid. Check whether the serial number record is correct. Otherwise, it does not belong to Apple procts
confirm whether your phone is iPhone 4 8GB black. Otherwise, it can be confirmed that the machine is a high imitation machine. It's not a real machine
the beginning of serial number c3k is the official renovation, which is provided for after-sales service to replace the faulty machine.

4. Hehe, the term "business swindler" generally refers to response speed, such as rendering speed. For example, when you look at 4K, moving objects will drag shadows, while when you look at standard definition 720, there will be no drag shadows. Because the data is too large, the response speed is not enough, and the processor can't react so fast

5. It depends on what minicomputer it is and its configuration

I have contacted 570595780 and other IBM minicomputers, and their performance has been greatly improved< At present, I mainly use 780 small computers, which are power7 + processors.

if we say flops
the previous generation of power7, an 8-core power7 4.1G is 264.96 gflops. Second kill Intel Core i7-980 Xe (107g)
while 7 + is more than 25% higher than 7. My configuration is 3.72g with a lower main frequency, and the performance is estimated to be similar to 4.1G of the next generation 7.

a fully equipped 780 minicomputer has 16 8-core CPUs, with a total of 4225gflops

6. Generally speaking, the common solution is to push once through ffmpeg, open the real-time mode, pull the stream from RTMP, add a scale, and then push it out through RTMP
in fact, the idea is to divide this requirement into three parts, get the video stream from the source, with sufficient computing power to ensure that the decoding and secondary coding speed are more than doubled, and then push the new stream back. What you want is only local implementation, so just open three dockers locally to run these three services
it's not clear whether the company specializing in live broadcasting has private and closed technology.

Huawei mobile phones have high cost performance: Huawei mate9, Huawei P10, Huawei glory V9, Huawei Changxiang 7, Huawei Nova 65g

1. Huawei mate9

Huawei mate9 is positioned as a business style with elegant appearance, stable color matching, 5.9-inch screen, all metal body design, equipped with the latest Kirin 960 processor, fully upgraded performance, built-in emui 5.0 customized system based on Android 7.0, and used 4000mAh high-density high-capacity battery and smart 5.0 technology, Support Super Charge fast charging technology

Huawei Changxiang 7

as a new machine just released this month, Xiaoya put it on the shelves on Friday. For customers, it is a combination of cost performance and practicability. The all metal integrated fuselage design has a thin fuselage thickness of 8.05mm, and the front of the fuselage is covered with 2.5D curved glass, Standard 5-inch 720p IPS display

5. Huawei Nova 6 5g

nova6 is a new machine that has just come out recently. 5g is standard, and its performance is even better than Nova 5. It is the first choice for young people. It can capture the favor of a large number of fans both in performance and design

Screen: 6.57 inch (LTPs) TFT LCD material, double hole full screen, resolution 2400 * 1080; Fuselage configuration: metal frame + glass back cover, fuselage interface is only equipped with USB type-C interface, the back is equipped with vertical three camera mole + single LED flash, laser focusing sensor

hand selection skills

1. Configure the same selection method

the same configuration, and choose mobile phone brands with large shipment volume as far as possible, because large shipment volume means that people have more experience in quality control, assembly, etc

2. Selection method for purchasing Internet mobile phones

it's better not to buy the first batch of new models launched by Internet mobile phone manufacturers. The reason is that the assembly line of the first batch of procts is not mature and there are many problems of workers' operation errors. If you're unfortunate enough to buy a problem cell phone, it's enough for you

3. Pay less attention to the press conference and more attention to the actual parameters

pay attention to a certain Internet mobile phone. Don't try to understand this model through the press conference, and try to see the actual parameters as much as possible, because in the press conference publicity, mobile phone manufacturers often take the good side of the mobile phone and cover up the bad side

8. I don't think it's a problem with the problem set. First you have to make sure. Has he really learned how to calculate problem sets just to consolidate his knowledge. If the knowledge itself is not mastered well. The question is meaningless.
