A recent cyberattack in France targeted refrigeration systems at hundreds of supermarkets, causing some units to reach 50°C and spoil fresh and frozen food. The attack also produced smoke and fire at some stores.
The incident highlights how someone can hack a refrigerator and why a supermarket’s cooling system would be connected to the internet. Modern refrigeration systems use electronic controllers to manage temperatures and regulate cooling, which can create a potential entry point for hackers.
The vulnerability in the refrigeration system was already known, and the manufacturer had issued fixes, but many affected units were running outdated firmware or had reached the end of their supported life.
Cybersecurity Concerns
The attack on French supermarkets is a reminder that cybersecurity is not just about protecting sensitive data but also about being mindful of how devices are connected to the internet. When appliances like refrigerators, baby monitors, and door locks are connected to the internet, a security lapse can have serious consequences.
It is not just about stopping devices from being connected to the internet, but about being mindful of what needs to be connected and what does not. This incident serves as a warning to businesses and individuals to prioritize cybersecurity and ensure that their devices are secure and up-to-date.
In a separate development, the Singapore government has launched a dating app called FirstDate, which uses a Nobel-winning algorithm to match users. The app is designed for public officers aged 21 to 35 and offers one potential match at a time, rather than presenting users with an endless stream of profiles.
A New Approach to Dating
The FirstDate app uses the Gale-Shapley algorithm, which was developed by mathematicians David Gale and Lloyd Shapley in 1962. The algorithm is designed to find a stable matching between two groups of people, taking into account their preferences and rankings. The idea is to prevent two people from abandoning their assigned partners for each other, creating an unstable matching.

The algorithm works by having one group propose to the other, and the proposers are either accepted or rejected. The process repeats until everyone has either found a match or exhausted their options. The outcome is a stable matching, where no two people have a mutual incentive to break away and form a different pair.
The use of this algorithm in a dating app is an interesting approach, and it will be worth watching to see if it can help people find love. By limiting the number of introductions and using a slow and deliberate approach, FirstDate is betting that people might make more considered decisions and focus on the person in front of them rather than wondering who else might be available.
A writer who reviewed the book “The Elsewherians” by Jeet Thayil noted that the book is a story about places as much as it is about people, and that it tells the story of Ammu and George across various locations. The writer fell in love with the prose and noted that the book is devoid of any agenda, simply telling the story of people who do not belong anywhere.
As technology continues to evolve, it is essential to prioritize security and be mindful of how devices are connected to the internet.
The FirstDate app’s use of the Gale-Shapley algorithm is a unique approach to matchmaking, and its success will depend on various factors, including user engagement and the quality of matches. The app’s focus on slow and deliberate introductions is a departure from the typical dating app experience, and it may appeal to users who are looking for a more thoughtful approach to finding a partner.
According to the report, the FirstDate app has been developed by Singapore’s digital government agency, GovTech, and is available to public officers aged 21 to 35. The app’s matching system draws on the Gale-Shapley algorithm, which guarantees a stable matching, provided everyone has ranked their preferences and the participants meet the algorithm’s assumptions.
Implications of the Algorithm
The algorithm is used to find a stable matching between two groups of people, and it has been used in various fields, including economics and computer science.
