Chronicle of Studying Abroad

After submitting the options, more than 50 groups were led by a volunteer and distributed to other rooms.

Each group has its own independent space, so there is no need to worry about ideas being copied by other groups.

The small room is not big, similar to the study room that needs to be reserved in the library of M University. One wall is a large floor-to-ceiling window, and the other two walls are hung with writing boards that occupy half of the wall. They are not blackboards or common whiteboards. It is a thin board with a translucent white and blue texture.The last wall is hung with an ultra-thin LCD screen, which can be connected to a computer and display the computer page on it, which is convenient for team members to communicate.

The whole room looks high-end and upscale, very futuristic and technological.

The seven people kept looking at the room just like Grandma Liu entered the Grand View Garden.The tension that had been simmering just now suddenly relaxed, like a balloon that had been poked and leaked.

Yuan Shan and others confirmed their goal again and again before officially starting to assign tasks-software design on air pollution.

Air pollution, which has plagued various countries in recent years, has scientists racking their brains trying to come up with ways to improve it.

Various environmental problems seem to have erupted suddenly, unfolding in front of human beings in an extremely cruel and undisguised manner, but in fact, they have already appeared at some inflection points in history, but human beings at that time did not realize or felt that they were still developing. more important.

There are many examples of inventions that once facilitated people have become life-seeking symbols for future generations.Even modern people are troubled by environmental pollution.

The reason why Wonsan and the others chose this topic is because they had discussed this issue together before, and secondly, they randomly selected a few hot topics for practice during the pre-match preparation. The first practice was air pollution.

So they took advantage of it this time.

Yuan Shan stood up, took a black oil-based marker, and stood in front of the writing board: "Although we have practiced this topic and listed many possibilities when preparing, it is impossible to copy and paste the written code directly. Come here, so the workload is still heavy.

We have to rewrite the code and make modifications, after all, what we wrote before is a preliminary draft. "

Yuan Shan turned around and began to write on the clipboard. He wrote "air pollution" on the top, and listed some of the solutions they had discussed in ascending order of numbers below.

A total of 5 items are listed. In fact, there were originally more than ten items, but some of them were filtered out because they were too unconstrained or impossible to achieve with current capabilities.

The marker pen was hanging on the blank space of the writing board, Yuan Shan turned his head: "Anything to add?"

Jessie collected the papers they had just brainstormed together, and marked some words with a pen. Grace held her chin in one hand and flipped through the papers with the other: "The result of the brainstorming is similar to what we have done before. Shan, what do you mean by sharing bicycles on your paper?"

Qian Keke was connecting her computer to the LCD screen, when she heard this, she raised her head and looked at Yuan Shan, both of them laughed.

Yuan Shan nodded to Keke Qian: "Keke, please pull up some information."

Qian Keke: "Understood." As she said, she tapped the keyboard several times very quickly, and a Chinese news popped up on the screen.

Yuanshan wrote the words "bicycle sharing" on the clipboard, and then said: "This is a popular project in China recently. It literally means bicycles that everyone uses together. For example, if I invest 100 bicycles in T city, These bicycles are placed on the side of the road at will. Citizens can unlock the bicycles anytime and anywhere, and just lock them at the destination. It is not like the citizen bicycles provided by government organizations on the market at present, which can only be used at fixed addresses. park.

In short, the bicycle sharing project expands the places that bicycles can reach, and it will not be so limited. "

Qian Keke called up several English news, some were reported by foreign media, and some were translated from Chinese.

William squinted his eyes to quickly read the news, and suddenly realized: "I seem to have seen this news a few days ago. I also talked with my parents. They said that the application of technology in life in country Z is really amazing."

Yali patted the table: "Shan, you don't mean to..."

Seeing everyone's understanding expressions, Yuan Shan couldn't help but praise in his heart that it's easy to talk to smart people. He nodded with a smile: "Yes, it's what you think. Since there is a ready-made technology in China, recently one of the bike-sharing companies The company has also entered the overseas market, and I believe that if we go to talk, they will most likely be willing to develop the market here.”

"It's Country E." Baron added.

Qian Keke timely called out the news that the shared bicycles were put into use in country E.

Jessie turned the pen around: "It's very feasible."

Yuan Shan smiled, and sketched the appearance of the bicycle on the writing board with a few strokes. He shook his head: "It is still early to cooperate with them. We only need to confirm that there is such a technical application."

If outsiders hear the conversation of these students who are only in their early twenties, they may scoff at them, thinking that they are whimsical, and they are just technical applications and business cooperation casually, which is unrealistic.

But the world has become very different in the hands of some people who dare to think.

"We can't make products that directly purify the air, but we can save the country with curves." Grace lay on the table, playing with a lock of her hair, shaking the curly hair, and raised the corners of her eyes to pick out mischievous With a charming arc, "It's the right word, isn't it, Coco?"

Qian Keke smiled and nodded: "That's right."

Their idea is actually very simple. Since the air cannot be improved directly, they should reduce pollution.

This is also the idea that environmental protection is being carried out all over the world today.

They are going to write a game.

Refer to the game of elves capturing and scanning ghosts that was popular some time ago, integrate the application of shared bicycles, and then add their ideas.But in fact, before they knew about shared bicycles, they had a similar concept, but in the end it was nothing.

This is the original idea of ​​FFE (FightForEarth).

In a class last semester, they learned how to combine hardware and software to achieve a goal.At that time, the professor of that class specially customized an early open-source hardware of Arduino, and the students could enter a specific program through programming, and then interact with the hardware to run and output the result.

At that time, Wonsan and Yali were in the same class. After finishing a timer required by the course, they got together to do another project.

Coincidentally, what they did that time was air quality detection and temperature recording.

Use external hardware to detect and input data into the database, and then through the hardware processor and software programming provided by the professor, finally successfully output and update the data on their social accounts in real time.

The result of the experiment is very good, although the process is very cheating because of unfamiliarity and various problems.

At that time, they also harassed the professor for the problems they encountered. The professor was very happy, but sometimes he was too busy, so he specially approved a doctoral assistant for the two of them to assist them.

With their final product, they were guaranteed by the professor to get full marks in this course before the end of the term.

Now, these past experiences have become their right-hand man, helping them to firmly build the foundation they need.

"I don't think anyone would like to have a measuring device on a mobile phone. Although the measuring device is small and inexpensive, where is it more acceptable?" Grace asked looking at the photo of the measuring device on the display.

William, Jessie, and Yali are working together, each coding the program.

Yuan Shan and Barron sat together to draw CAD drawings and internal circuit diagrams on the computer, and Qian Keke and Grace were building the database needed for the experiment.

"I was also thinking about this question just now. There are several plans. One is family as the unit, the other is public facilities, and the third is businesses." Qian Keke cut out a location map on the display screen, based on their location in Will The center is the center of the circle, with a radius of 500 meters as a garden, and a red circle is circled.

Yuan Shan was drawing the circuit diagram freehand, looked up and said: "Family is not easy to promote, businesses can consider it as an NPC, which can also be used to promote investment in the later stage. I personally recommend public facilities, one is a wide range ; The second is that only one object needs to be communicated, that is, the government; the third is that there are many types of objects to be carried.

We don't just need to mount the measuring device in a fixed place, mobile measuring devices can also be considered. "

"For example, the bus, the subway?" Baron asked.

William, Yali and Jessie are completely immersed in the ten-inch screen in front of them, and they don't hear anything outside the window.

Yuan Shan snapped his fingers, pointing his fingertips at Barron: "That's right. It's like a variable in an ordinary chemical experiment."

Qian Keke tapped her lower lip, and pondered: "The recorded data of air quality changes in fixed areas is already huge, and adding the mobile measurement data will make the most of it?"

"What Coco said is what I'm worried about. Our current hardware configuration can't keep up with the processing speed." Grace sniffed at the ends of her hair, curling a few curls around her fingertips.

Barron moved his fingers slightly, glanced at Grace, then turned his head and said to Yuan Shan: "Mobile measurement can be regarded as a later stage of progress. It is better to focus on fixed-point measurement for now."

Yuanshan has no objection: "What you say makes sense, let's put the mobile measurement on hold for now. Time is tight, and I can't make it in a day and a half. I will save it as a follow-up development when I make a speech."

Yali on the side raised his head and raised his hands to cheer: "Great, I support your decision, Shan!"

Jessie's eyes left the computer screen for a moment, and then immediately glued back: "It's the part that Yali is in charge of."

Facing everyone's "Oh——" expressions, Yali smiled awkwardly: "Well, this is the most difficult problem to solve, okay, I can spend several months on it. And, Grace also said, Our hardware is not hard enough."

He said with a weird smile and blinked his eyes.

The four boys present all looked at him with condemnation in their eyes.

The three girls were doing their own thing, but the strange arc of the corners of their mouths seemed to say "I understand what you're talking about".

After four hours of high-intensity mental exercise, after the volunteers knocked on the door to remind them that they could go to lunch, everyone collapsed on the chairs in unison.

Everyone's expressions were dumbfounded, their brains were blank, and they were saying words that they didn't understand, as if their bodies had been hollowed out.

"eat first?"

"Ah? Encountered an infinite loop, unable to jump out."

"That's right, me too. I just applied for a GPS positioning system with the organizer."

"Why can't you escape?"

"Can't run out? Yes, yes, the value of the circuit simulation result is wrong."

The chicken and the duck talked for a while before the brain came back to its senses.Everyone looked at each other and suddenly laughed.

"Let's eat first and take a rest." Yuan Shan stood up and stretched himself.

Everyone nodded, saved their progress, got up and walked out the door.

Yuan Shan was at the end, as if remembering something, he took out his phone and looked at the quiet desktop.Click on the WeChat icon, and the first one on the top is Qin Shui.

Qin Shui's profile picture was changed to a person's back at some point, a very familiar photo.

Yuan Shan quickly remembered that he had seen it there, and it was one of the 9 back photos that Qin Shui posted on Weibo before.Yuan Shan lay on the table in the coffee shop and couldn't help laughing.

Yuan Shan smiled lightly, and also changed his avatar to go up.

It was a photo of Qin Shui giving a lecture in the classroom.

With his back to the students sitting below, he was writing mathematical formulas on the blackboard with chalk.

After finishing this series of things, he sent another message to Qin Shui: I'm going to eat.

Then he exited, and the screen of the mobile phone that was about to be locked by him was the silhouette of Qin Shui.

So, no one knows who is an idiot.
