(Fighting against New Coronary Pneumonia) Keep the "Shanghai" log: the "code" behind the screen supports the programmer as a "digital epidemic prevention person"
China News Agency, Shanghai, April 24th telegram: Keep the "Shanghai" log: The "code" behind the screen supports the programmer to become a "digital epidemic prevention person"

In a community of nearly 4,800 people, how to ensure that every nucleic acid test notification is in place, Shanghai Pudong Huangshan Shixinyuan adopts "online and offline" simultaneous calling.
Offline, volunteers shouted the building with loudspeakers, and the online "every household knows" applet updated the progress in real time, and two kinds of "broadcasts" sounded at the same time.
Different from the former "sleep and miss", "every householder" can read historical news, quickly and accurately know when the nucleic acid test starts, the specific location of each test point, the building number in progress, and other important information.
Wang Qinghe, the person in charge of Shanghai Riqin Information Technology Co., Ltd. and a small program developer, called it a "community telegram". Through one-way communication, it can reduce the interference of invalid information and avoid the coverage of focal information.
"There are 4,780 people in Shixin Garden in Huangshan, and the highest number of readings is 650 people. We think it may have covered 20% of the residents." Wang Qinghe said.
"Big speakers, small speakers, maybe 50%-60% of people know, some people didn't hear it, and the news passed immediately, not covered. We will send it to the online group, and we will increase it by 20%-30% on this basis. , and then the applet goes up to 80%-90%, or even 100%." Wang Qinghe said.
He hopes that "every household knowledge" will be a powerful addition, and finally achieve close to full marks for community work.
In Xinjing Qi Village, Puxi, Wang Feng, a senior engineer at Shanghai Yiyi Network Technology Co., Ltd., also developed a small program for residents to check express information for free, so as to alleviate the anxiety caused by the "last 100 meters".
According to him, there are more than 5,000 residents in the community and thousands of parcels are delivered every day. Most of the existing volunteers take time out of their jobs to do volunteer activities.
It is arduous and inefficient to communicate with each other by calling the building to connect package information or WeChat group.
"The most impressive thing is that a volunteer delivered it at around 12 o'clock in the evening for several consecutive days, and it has been delivered since he got off work at 7 o'clock in the evening. It was very hard." Wang Feng said.
He understands that people who expedited delivery, such as cold meat, can't keep it for a long time, and they can't know the information about the arrival of the package. Many residents have psychological anxiety.
From 9:00 on April 20th to 20:00 on the 24th, the small program was launched. The volunteers released a total of 716 pieces of information, the number of packages reached 2,203, and they were queried 13,696 times.
"I feel quite relieved. For us, the high utilization rate of the program is a very fulfilling thing." Wang Feng said with a smile.
After going online, he optimized and iterated the program again.
According to the usage of residents and volunteers, the number of packages is precisely the number of packages, the arrival time is changed to the start time of delivery, and the "remarks" function is added.
In the process of fighting the epidemic, various technical supports are indispensable for optimizing community work.
Since mid-to-early April, when Shanghai residents participate in nucleic acid testing, the on-site registration method has been adjusted to a "nucleic acid code" that they can carry with them.
After the screenshot is saved, the code can be used repeatedly within 30 days, which helps to improve the efficiency of on-site nucleic acid sampling.
The "Apply" applet on the Alipay terminal continues to add functions, in addition to the "nucleic acid code", there is also "nucleic acid assistance for the elderly and young".
Recently, the number of users of these anti-epidemic tools has surged, and it is particularly important to ensure the stability of services. Alipay project manager Huang Yanqing has settled down in the Shanghai Big Data Center Office.
"From receiving requirements, prototyping, interface connection, function development, and even the final pressure test in one go, the usual one or two weeks of work was developed and launched in one night." Huang Yanqing said.
The development and maintenance of programs is never a one-click execution.
From "Community Telegram" and "Express Inquiry" to as big as a city server, behind the screen are programmers who stick to it silently.
It is these "digital anti-epidemic people" who fix epidemic bugs that allow the city to continue to operate efficiently.
