In the action movie, there must be a super skilled hacker, they are always hiding in the house in the train, the image is also very fixed, a pair of nerdy appearance, drinking coke wearing headphones, rarely face to face with the gangster game.

But their mission is always critical, hacking into firewalls to gain access to confidential information, shutting down surveillance, opening doors and closing doors. No matter what big events come, they are always on hand to seal the victory.

In fact, they have been guarding the world.

Case 1: In-depth investigation into the flow of problematic vaccines

These days, changchun Changsheng’s problem vaccine shocked the whole country. In the face of the national economy and people’s livelihood, a programmer spent 14 hours using publicly available information on the Internet to sort out the details of vaccine purchases by provinces across the country in recent years.

The unnamed programmer has hosted the entire survey on GitHub, which includes the vaccine procurement lists of provinces and cities for 2016-2018. Due to the special nature of the provincial websites, no crawlers are used.


Instead, it was manually retrieved and downloaded, a process that took nearly seven hours.



In a recent update to the project, the programmer explains some of the problems and explains why he did it.

To these achievements, he offered only modest responses. Although this procurement detail is not for all the batches of problematic vaccines, but this open and detailed data, let more ordinary people realize that individuals can also participate in the supervision of public power, so that the question is no longer perfunctory, let the truth from the citizens further.



Case 2: A hero for ALS patients

In the past few years, an “ice bucket challenge” has been spreading across social media sites around the world to help bring ALS patients to the attention of all, from presidents and celebrities to Internet celebrities.

ALS, also known as amyotrophic lateral sclerosis, is a motor neurone disease (MND). The disease affects nerve cells in the brain and spinal cord. In addition to making it impossible to walk or eat, patients gradually lose the ability to speak.

A group of programmers stepped up. Lyrebird, an AI technology company, teamed up with ALS-focused ngos to create an app that allows ALS patients to speak in their own voices. The project is called Revoice.





With Lyrebird’s deep learning algorithm, patients only need to provide high-quality recordings of the first two to three hours of illness, and the algorithm will record timbre, pitch and other features to generate a unique sound, which will be used as a reference for the microphone.

Combined with an auxiliary reader, you can communicate with your own voice just by looking at text on the screen. Just like Stephen Hawking’s ALS generator, Hawking’s microphone only produces a featuresless robotic sound.

The technology allows patients to communicate in their own voices, but the system has the patient’s voice data in advance when they are healthy. If the patient can’t provide this information, the system has a hard time generating sound.





To that end, the Revoice project will open up its library later this year so that more ALS patients can store their voices before their disease worsens, so that the generator can be customized for them and will be in use by the end of the year.

The ice bucket Challenge has made the world pay attention to the ALS community, and the society is taking practical actions to help ALS patients build confidence in life.

The Revoice project is one of the most useful and motivating ways for patients to communicate with their own voices through technology that may change their way of life in some way.

Case 3: Rainforest Keeper

Tropical rainforest is a rare and precious treasure on the earth, maintaining the local ecological balance, but there is still a large number of illegal mining, poaching, affecting the fate of the rainforest and the local people, flora and fauna.

Engineers at Rainforest Connection, a non-governmental, non-profit environmental group, are using TensorFlow to protect the planet’s rainforests.





By installing a device with solar panels, they can monitor the rainforest 24 hours a day.

All the sound is uploaded to the cloud for analysis. From a large number of sound data to find out the audio that is different from the natural state, such as gunfire, chainsaw sound, truck engine sound, and so on, determine the sound and location from loggers or poachers, and timely transmit to the local police and protection organizations.





The Rainforest Connection system has been installed in tropical forests in Sumatra, Indonesia, Cameroon, Northern Brazil, Ecuador and Peru, and can be heard live on its website.

Like all superheroes, programmers use their keyboards and code as weapons to build a powerful shield for us.
