Wang Yinan then called Qian Zhonghua, it is not easy to find a place with enough clearance near the city, this matter can only be done by Qian Zhonghua, of course, if Qian Zhonghua can't do it, he will find Qian Lao to do it, anyway, Wang Yinan is relying on their family.

Hearing that Wang Yinan was going to build an air-space integrated R&D center by himself, Qian Zhonghua was very happy, "This is fun, you must call me when you test", Qian Zhonghua said, "As long as you agree to me with this condition, what is the meaning of clearance",

"It seems that there is such a thing as an aerospace license, then you need to at least have a pilot license", Wang Yinan said, "It seems that I will also get a better one, and I still have to ask Chief Yang for help when I go back."

Xianglong's test work ended smoothly, the multi-channel transponder manufactured by the Ministry of Electronics Jinling also carried out the actual machine joint commissioning, and finally carried out an actual combat simulation, looking at the front of the integrated combat UAV, through the clear image of the two Xianglong UAVs transferred back, the eager look in the eyes of Chief Yang could not be concealed.

"Let's not talk about you, a stratoplanar prowler, and a few Xianglong UAVs for the UAV combat unit alone can also greatly improve the combat capability", Chief Engineer Yang said.

"First of all, the strike distance of the drone has increased several times, and the resolution of the transmitted image has also improved a lot", Wang Yinan nodded,

"In addition, compared with the traditional satellite communication scheme, the delay is reduced by more than an order of magnitude, which also has a huge advantage in the issuance of combat orders and rapid response."

"The only problem is the solar panels", Mr. Yang said, "the solar panels in the upper part of the Xianglong greatly reduce the stealth ability of the drone, and the lower part is fine, but if it is similar to the blackbird that is 30,000 meters above the altitude of the reconnaissance aircraft, it can easily find and hit the Xianglong communication node."

"You are a fan of the authorities", Wang Yinan was happy, "The use of battery panels is for the requirements of long-term battery life, for Xianglong UAVs with combat needs, it is a big deal not to install it, sacrifice a little endurance to ensure stealth performance, anyway, it will be no problem to fly for a day."

"Good idea, the solar panel is made detachable, and it will be dismantled in wartime to ensure stealth, and it will be installed for training or peacetime tasks", Chief Master Yang patted his thigh,

"It seems that it is necessary to get a simplified version and sell it to the oil boss in the Middle East", Chief Yang's eyes narrowed into a line with a smile, probably remembering the small money flying all over the sky.

After completing the test subjects, the 116 Institute, including the prototype, manufactured a total of five Xianglong UAVs, all of which were loaded into an Air Force transport aircraft, and flew directly to the Southern Military Port with the on-site operation and maintenance personnel of the 116 Institute and the Jinling Institute of the Ministry of Electronics.

The next search work is nothing to do with Wang Yinan, this domestic competition of various types of UAVs is directly related to the purchase orders of the troops in the future, so several major aviation research institutes, as well as two private UAV research and development companies are full of energy, counting on showing their style in the South Pacific.

And Wang Yinan quietly returned to the imperial capital, Dream Science and Technology Building, David Group, and he got the latest test version of Laihi.

The first thing to complete is the beta version of Android, although the IOS version has been completed simultaneously, but in view of the censorship mechanism of the AppleStore, Wang Yinan feels that it is better to talk about it slowly.

The icon of Laihi is a virtual image on the moon about to walk into a portal, which means face-to-face communication across space, of course, this is the meaning that Wang Yinan thinks himself, but it still looks cool.

The App starts very quickly, because there is no baggage left over, all the code is built from scratch, and there is also the Gödel system to check the quality of the final code, "very good", just this opening speed, Wang Yinan couldn't help but praise the team.

If there is a lot of legacy code that does not dare to move around, it is not so simple to speed up the startup, remember that there is a well-known enterprise App, the user base is very large, but the startup is very slow, no matter how good the machine, how fast the network, it is always at least two seconds to enter the user interface.

The newly taken CTO and a group of programmers couldn't find the reason, and finally had no choice, so they found a few debugging masters, dotted all system calls before and after (that is, the meaning of timing), and finally found that all the threads would be forced to sleep for two seconds in a hidden module.

After finding the API call, I went back and searched for the source code, and finally found a forced sleep instruction hidden in a so-called cross-platform library, followed by a line of comments, "Must force sleep, remember that the boss asked to reduce the value when optimizing", this guy is also very smart, and the annotation written in pinyin.

The new CTO spurted out a mouthful of old blood, but there was no way, the previous master was the master who brought him out single-handedly, and he was still embarrassed to do the thing of killing the master and preaching, so in the end he had to stop it.

After opening Laihi, if there is no action, a video will be played, this video is a real-time scene of multiplayer 1080P video chat recorded using the latest video compression/decompression library provided by Wang Yinan, if it is on a mobile phone with a 2K screen, users can immediately feel the shocking effect.

After skipping the video,It's the login process,First of all, users are asked to enter their mobile phone number,Originally, Qi Feng suggested a trial version that doesn't require registration,You can directly come in and watch a variety of high-definition programs,Considering that this is similar to the function of a large number of live broadcast software on the market,Wang Yinan finally decided not to release this version for the time being to stimulate the live broadcast apps that have become a mess (including pepper, of course).

After entering the mobile phone number, it is a regular operation, they simply omit the process of setting a password, generate a dynamic password on the machine, and as long as the verification code is correct, you can log in by binding the current device.

Then there is the selection of avatars, this time the David team did not cut corners, and hundreds of 3D avatars that the artist spent months making came to use, and users were free to choose their favorite avatars.

What's more,Use the camera to take a photo of the user,The program compiled by the neural network can generate the user's face outline,And then automatically find the most like you3D avatar word from the avatar library as the user's default avatar,Wang Yinan played on this function for a long time,Finally, I was very depressed to find that the most like myself is actually a chipmunk avatar,And take a closer look,The demeanor is really similar。

After the login is completed, the next step is the most difficult step for an app that is positioned as a social network.

"How do you start your first video conversation?" In order to naturally guide users to use the core function of video chat, Wang Yinan and they held countless meetings to discuss.

"As long as users use our high-resolution multi-person video chat feature once, I believe they will never uninstall our software again," said Wang Yinan when discussing this key feature point.

"So, the key to everything is how to encourage users to use multiplayer or even single-person video chat for the first time."

"The objective situation now is that for the vast majority of users, after opening the Laihi App, it is empty and there are no friends", Chen Zihao said, "In this case, what should we do"?

The version that Wang Yinan has now is the crystallization of everyone's wisdom after many discussions some time ago.

In addition to an empty address book column, there are two columns,Blank address book column,This can't be helped,You can only fill in the address book gradually in the process of user use,Of course,There is also a very intimate function for this address book,

That is, every time it starts, it will automatically scan the user's address book, of course, for privacy reasons, it will not upload the phone number in the address book to the company's server, but transmit a one-time MD5 summary of the phone number, when a friend in the user's address book registers to come to Hi, the server will immediately find out, and notify both parties.

Users only need to click to confirm, and they can contact your contacts friends in Laihi.

The other two columns, one is "Come to Hi Square", this one is interesting, Wang Yinan found some stars through Zhou Hui, and when he was on the set, or when he went out to travel, he used Laihi to record high-resolution videos, and the audience could watch it after clicking on it.

And if you are interested in participating in the discussion, you can choose the connection function, you can connect with the guests and other users to discuss online, and at most you can support 9 people to have a video discussion at the same time.

The red-clothed leader was not willing to be lonely, and asked for two positions, saying that he wanted to release and update every day, and he also invited some other IT leaders to show their faces in the square (of course, there are no goose factory shares in the company).

Wang Yinan clicked on several programs in the square, and in general, the high-resolution effect is still very surprising.

"But there's a problem", after watching it for a while, Wang Yinan always felt a little awkward, he picked up other live broadcast apps and short video apps and compared them for a long time, and finally found that the video of Laihi is the clearest and smoothest, and the effect is the best, but the girls and stars in it seem to be beautiful without anyone.

Wang Yinan slapped his thigh, "We don't have a beautification effect, this can't work, you can still watch it without a beauty star."

Qi Feng nodded, "We have evaluated several beauty algorithms, including some open-source and fee-based libraries," Qi Feng said.

"At the moment it looks like ArcSoft is the best, but there are still some cases of over-rendering",

"Money is not a problem", Wang Yinan nodded,

"Since ArcSoft has the best effect, let's buy a license", Wang Yinan, who has earned several small goals in half a year, is qualified to spend big.

Another column is "Let's Hi Together", this is a game-like thing, the system will publish various tasks, for example, the first task is to invite a friend for a video chat, after the user selects this task, a text message will be sent to the user with the specified phone number in the address book, which includes the download address of Laihi.

The next tasks include starting a multi-person chat, forming a group of relatives and friends, forming a classmate, and so on (in fact, it is a prestige group).

Wang Yinan looked at the final task rewards, including user levels, user points, etc., "Are these rewards after completing the task?" Wang Yinan asked, "We are also going to make some small avatars, small dolls and the like", Qi Feng said,

"It's too stingy", Wang Yinan waved his hand,

"I'll ask if the cost of the VR glasses from last time can be reduced a little more, and let's get hundreds of thousands as a reward", Wang Yinan, who has a lot of money, made a decision amid the cheers of everyone.

After putting forward some requirements for the details of Laihi, Wang Yinan said to Chen Zihao, "The version of the integrated beautification algorithm must be completed within a week, and the testing work should be more comprehensive and cover more models, which is the final version for the market."

"It's time to come out next month to face the wind and rain of the market",

"But before that, there are two more important things to do," Wang Yinan said to himself in his heart.

Hot book recommendation: The new work of the catty god ", the new book of the god of forgetting, the new book of Chen Fengxiao, the new book of the god of taste
