After a brisk plucking of the strings, the song sounded: "In my dream, the air began to smoke. The perfect face in the haze slowly appears, goodbye ugly duckling, goodbye! I want to change my mind, people will be able to win the sky, and the dream is close at hand!"

Accompanied by the rhythm of the music, two figures, one pink and one white, danced. To be exact, a long-haired girl in a pink dress is dancing, and a boy in a white and white suit is standing behind her, just dancing handsomely.

When the accompanying music sang the lyrics of "Beauty is the limit, there is no end to loving beauty, the realm of perfection is pursued, people who don't love beauty will be destroyed!", suddenly more than a dozen green objects flew out of the hands of the man in white, scattered and flew to the top of the cave. Before hitting the roof of the cave, the green objects lost their rising speed, and just as they were about to continue their trajectory according to the parabolic equation, the green masses suddenly exploded in the air, scattering white pink and red petals, creating a romantic scene of rain in this area.

Although standing behind the camera tripod was not in the main coverage of the flower rain, many of the fluttering petals still fell on Lu Xinquan's shoulders and hair.

Reaching out and tipping up a petal that fell on her chest, her professional knowledge quickly analyzed that this was a moon petal, and it was the kind that was not fully developed, thinking of the bag of flower bones she handed over to Atletico Madrid before, she suddenly understood that those flower bones were used to make this petal rain special effect, and couldn't help but sigh in her heart: "You guys are really good at playing!

This is the mountain tunnel connecting the headquarters of Luda University and the student apartment of Zengjia Village, which has become a large number of Luda students since its completion two years ago, to be precise, it is the traffic artery that the third and fourth year students of some colleges must pass through every day, which does not include Tang Jiayi and Lu Xinquan and others who live in the women's dormitory of the main department, but there are some things that attract girls.

I don't know who was the first to start graffiti on the slippery tunnel wall, anyway, by the time Lu Xinquan and the others moved to the headquarters, the graffiti in the tunnel was already on a large scale, even if the school changed to a darker light half a year ago, it couldn't suppress everyone's enthusiasm for graffiti. While there are some elementary school-level graffiti like "Tian Yu I like you!" or "Chang Ji is a big fool!", more often than not, these are large graffiti patterns painted with paint. After all, Ludao University is a comprehensive university that is biased towards liberal arts, and there is naturally no shortage of guys with all kinds of literary and artistic cells on campus. Compared with the desks in the self-study room of the public classroom, this tunnel of more than 1,000 meters is a huge picture scroll of a kilometer long for you to sway, and at the same time, people come and go here every day, so that more people can see their graffiti works than painted on the desks.

Soon, it also became a new attraction on the campus of Ludao University, a famous tourist attraction in Ludao City, and was known as the most literary and artistic tunnel in the country. There is more and more graffiti in the tunnel, but there are more tourists who "visit here" and take pictures with scissor hands.

"But it seems that I haven't seen anyone taking pictures here lately, could it be that the warning is true?"

Looking up left and right, Lu Xinquan found that although tourists on both sides also had SLRs around their necks or card cameras in their hands, it was rare to see anyone raise the camera and press the shutter. After looking for a long time, she finally saw a male tourist take out his mobile phone and graffiti on the wall, but the person soon found that his mobile phone was abnormal, only to see that the person first repeatedly operated the mobile phone several times and seemed to be fine, and then grabbed the mobile phone in his hand and shook it up and down, so she almost couldn't help laughing.

In the end, the man still failed to do so, and scolded and operated the phone under the reminder of others, presumably resetting the phone.

Turning his head to look at the DV on the tripod in front of him, Lu Xinquan saw that the synchronization picture displayed on the LCD screen was normal, clear and sharp, and the focus kept chasing Tang Jiayi's forehead, and the movements of the third sister were clearly recorded, and this DV was obviously not affected in any way. Lu Xinquan felt as if he had caught a horse foot of the super hacker who poisoned graffiti, and there was no doubt that that person was Atletico Madrid.

For these annoying psoriasis, the students of Heron University are naturally very annoying, just like no one likes to be splashed with paint on their doorstep. Lu Xinquan Atletico is no exception, but Atletico is relatively more rational. In his opinion,These text graffiti are actually the same nature as the barrage comments on his own 2 stations.,It's just that the barrage subtitles like all kinds of "wild subtitles" will receive a lot of praise and thanks, and the barrage is always a minority,And most of the barrage are actually simple emojis, and there is nothing meaningful such as "Grandma, I like you" and "My sister is mine, others dodge" and so on. Similarly, there are always a few graffiti with beautiful handwriting, and many people find it difficult to think of any precise words to describe their feelings for a while, so they can only simply and rudely use a sentence "so-and-so to visit here" to commemorate it.

For these less interesting and valuable "barrages", the best way to deal with them is to remove them regularly, rather than leaving them there as an eyesore. It's like 2 stations have a barrage importance ranking for video barrage comments,According to the order of color violence、Foul language、Meaningless、Repetitive、Ordinary,The shelf life of different levels of barrage is different,The shelf life of the color storm is zero and it is automatically cleared when it is identified,And the retention period of ordinary barrage is as long as three years,But when the cumulative barrage of the video exceeds 1,000, it will be cleared according to the chronological order of publication"Redundant and stale" ordinary barrage。 The setting of the upper limit of a single video barrage comes from the Japanese Nico station, and it has also been inherited by station A and station 2, because too many barrages can easily lead to screen jams that affect the viewing experience, and the ordinary barrage that is cleared will only exist in the comment area below the video in the form of ordinary comments.

In fact, even if it is a beautiful graffiti, with the passage of time, the paint pigment oxidation and aging will become gray and mutilated, and will eventually be slowly eliminated unless someone updates and maintains it from time to time.

Therefore, Atletico Madrid found a group of classmates who had the same rational thoughts as him, and they set up a student group called "Furong Barrage Management Team" in the headquarters, volunteering to use their free time on holidays to manage and maintain the graffiti in the Seremban tunnel. They drew a line near the ground on the tunnel wall, marked with "mileage meters", to determine the coordinate system in the tunnel, and then used the coordinate system to register the graffiti works in the photos, and every week they regularly cleaned up the poor quality graffiti, and at the same time maintained and restored the fine graffiti. The rules for cleaning up graffiti and the rules for maintaining and updating are put on the forum and voted on by everyone, because the real name of the campus forum account corresponds to every teacher and student, which can be regarded as promoting democracy.

If all kinds of words such as "I have been here" and so on with a marker pen are just psoriasis can be out of sight and out of mind, and later there was a "barrage group" for regular maintenance and cleaning, and the damage caused by it has been effectively controlled, the tunnel congestion caused by the surge of tourists and the resulting "traffic accidents" have made the students of Heron University even more distressed and irritable. On more than one occasion, students rushing to class collided with tourists who were moving slowly to watch the graffiti in front of them, and several cameras were dropped.

However, since the beginning of this semester, some people have posted notices at both ends of the tunnel, saying: "Graffiti is poisonous, please do not take pictures! Using digital photo and camera equipment such as DC, DV, PP and other digital photography and camera equipment to shoot poisonous graffiti in the tunnel may cause system failure and inability to focus." ps: If there is any abnormality, please reset the system immediately to get back. ”

Soon after the notice was posted, it was photographed and sent to Tingtao BBS, at first everyone was only a prank at the time, feeling that this was just a weak warning like "orchard poison, please do not steal", there are many unbelieving students who take out their mobile phones to verify, as a result, some people said that their mobile phones are normal, and some people have reported that their mobile phones are "poisoned", how can they not focus when the camera mode is turned on, and it will not return to normal until the mobile phone is reset and all the data used is cleared.

Ordinary students were glad that they would no longer be afraid of hitting the trench of the SLR when riding a bicycle in the tunnel; computer software professionals were analyzing how the other party had poisoned the virus, and how did this virus targeting the digital photographic and video module be realized? Can it be realized in other places? While the law students started a debate to analyze whether the student who poisoned the tunnel graffiti had violated the law, for what law, and whose interests had been infringed? What are the benefits? Is it the copyright of the graffiti author, or the school's ownership of the tunnel, or the property rights of the camera and mobile phone in the hands of tourists? Are the settings information, application software, and various user files lost due to the reset of the mobile phone part of the property rights?

Ordinary students were pleasantly surprised, tens of thousands of digital SLRs could not be used here, but the same expensive film camera appeared. Graffiti on the wall is toxic and can make digital cameras malfunction, but not traditional film cameras. Some shrewd students and vendors saw this business opportunity, and gradually began to set up stalls on both sides of the tunnel to rent cameras, especially Polaroid cameras that can directly produce photos, and the business was very good. But as a result, the traffic jam at both ends of the tunnel has become even worse.

In the wake of the digital camera craze, Polaroid, which produced Polaroid cameras, went bankrupt in 2001 and was sold, and last year Polaroid closed its last Polaroid paper line. Although Polaroid launched a new generation of Polaroid cameras this year, the principle is no longer the same as that of traditional Polaroids, and it has become a digital camera with a micro printer. This is undoubtedly a betrayal of the faith of Polaroid camera enthusiasts, who would rather buy a second-hand refurbished old model than a new digital Polaroid.

According to the reasoning model of "whoever gains the most is the most suspicious", some people believe that the hacker who poisoned the graffiti should be a die-hard fan of Polaroid or film cameras. His poisoning of the tunnel graffiti pattern is just an experiment, and if successful, he will release more "graffiti viruses" out to combat digital cameras and remind more people of the good things about film cameras.

However, two months have passed, and this particular virus has only appeared in the Heron Hibiscus Tunnel, and has not appeared elsewhere.

The "poison" on the graffiti has been extracted by the students of the software department. They extracted several special computer viruses from dozens of sample phones and cameras, which confirmed that they caused the camera software to fail to focus. Different varieties of these viruses target different camera systems and camera software, and are named "Tuya virus type 2 ABCD" by the school's anti-virus experts. The word graffiti indicates that the virus is extracted from the graffiti pattern, and the serial number of ABCD corresponds to different camera systems, while type 2 means that this is the second form of the virus, although running type 2 virus in special debugging mode can immediately cause the camera focus function to fail, but transferring type 2 virus files to the same model camera through conventional file methods such as SD card, TF card, data cable and other methods will not cause camera poisoning. Considering that the graffiti virus is actually infected through photography, it is believed that there should still be a "graffiti virus type 1" in the form of images.

But to everyone's distress, so far they have not been able to find a way to extract the "graffiti virus type 1". Although countless experiments have confirmed that some graffiti patterns in the tunnel are abnormal, the camera will quickly malfunction and fail to focus when the camera turns on the photo mode for them, and after modifying some parts of the graffiti, it will become normal graffiti.

With this clumsy approach, they narrowed their suspicions little by little, trying to find the graffiti pattern that really caused the camera poisoning by elimination. However, they soon found that the activity of the virus hidden in the graffiti seemed to be reduced, and it was no longer 100% inevitable infection, and it seemed that the integrity of the pattern was compromised, or that the change in lighting would affect the "activity" of the virus. All kinds of factors are entangled, so they have not yet analyzed the specific impact of various factors on the activity of the virus, let alone extracted the "type 1" virus in the form of images.

Faced with this dilemma, some students gave up, and some action-oriented students changed their thinking, since they couldn't find the virus, it was the same to find the black that spread the virus. They used stupid methods to destroy some of the viruses on the graffiti, and then crouched in the tunnel, staring "alertly" at the people who had scribbled on other people's graffiti, hoping to find the hacker who had re-poisoned it.

But their efforts were undoubtedly unsuccessful, the virus was destroyed one day, and the next day they tested the digital camera, and they found that the camera was bricked again, but it was clear that they didn't see anyone touch the graffiti. A few times, the school began to have the legend that "graffiti hackers" were not people, but alien creatures or other demons. Some students who "worked" at the student activity center in the branch of the Seremban Tunnel at night said that when they returned to the dormitory at night, they saw a black figure hanging upside down on the top of the tunnel, and they ran back to the dormitory without daring to look closely.

For nearly two months, the graffiti virus has been stubbornly present in the Seremban Tunnel, and slowly there are no longer many tourists taking pictures here, and the Polaroid rental booths outside the tunnel have also been banned by the security department, because the road occupation business affects traffic.

However, seeing that Atletico's DV was completely unaffected, Lu Xinquan immediately had doubts in his heart, knowing that the graffiti of the boy and girl kiss they used as the background was a famous poisoning point. Thinking of this, she took out her rainbow flower, first manually backed up the data, then uninstalled the TF card, and then turned on the camera mode to face Tang Jiayi's direction. Sure enough, soon the video preview on her phone screen became blurry, "Sure enough, it's still poisonous!" she said to herself.

"Don't be discouraged, just put your ideas aside! Start changing now, and sparrows can fly into the sky!"

Lu Xinquan, who was thinking about how to coerce and blackmail Atletico Madrid at that time, didn't hear that the song was over, and suddenly saw a green object flying towards her, and then with a sudden "pop" sound, a rain of pink petals exploded in front of her eyes.

"Ahh

glanced at Ma Jingyi hatefully, Lu Xinquan thought about it and reached out to Tang Jiayi's wrist, "Jiajia, I suddenly want to arrange flowers, let's go first!

As for the thing she just thought about coercing Atletico Madrid to tell the secret of the graffiti virus, she was also dumped in Java.

The tunnel floor near the three of them was covered with petals of various colors, and the farthest was even sprinkled a hundred meters away, which was properly cleaned up by Atletico Madrid.

However, she obviously miscalculated, and Atletico Madrid did not frown at all, but first walked over and turned off the DV, and then took out a white plastic plate from the backpack on the side and put it on the ground. The plate quickly spun on its own, and the small brush on the edge spun, sweeping all the petal dust on the ground into his belly. It turned out that Atletico had already prepared this sweeping robot when he decided to use flower buds to release artificial petal rain, and at this time, he didn't have to worry about the rest when he released it to turn on the automatic sweeping model.

By the time Atletico put away the DV, tripod, mini stereo and lamp reflector umbrella for filling light into the large backpack, the sweeping robot had already swept all the petals on the ground. However, the ground under his feet looks even dirtier and messier than just now, just now it was full of colorful flowers, but now it is a mess, this is the "trajectory" left by the sweeping robot sweeping the ground, it feels like a schematic diagram of Brownian motion in a middle school physics textbook.

"Well, it seems that there is still a problem with the current path-finding algorithm!" frowning and looking at the traces of twists and turns on the ground, Atletico couldn't help but think. For mobile phone users, please visit http://m.piaotian.net
