- The Chinese taxi app DiDi shows red traffic lights along the taxi’s route with a countdown to green, so the user understands why the taxi is stopped and when it will move. These lights are also displayed in the driver’s navigator.

Not another fork, but a purpose-built editor designed for collaboration between humans and AI, delivering a lightning fast agentic editing experience. zed.dev/blog/fastest...

- Hiring in software industry is broken because the evaluation steps are based on dogma (“everyone does it like this”) instead of a rational approach (identifying needs and testing efficiently for them). This leads to massive wasted time and a huge false negative error.

- Remult is my favorite sync engine for prototypes. Instead of fetch() or RSC, you define the data schema and backend & database is created automatically. Remult now has a new website that does a better job of showing how brilliant this idea is. remult.dev

- At the beginning of the war, when we feared nuclear war, we bought a simple feature phone with an FM radio that would work for weeks on battery (Nokia 800 Tough). Yesterday during the blackout in Spain, it came in very handy for listening to news on the radio.
- Yesterday's apocalypse simulation in Spain showed that we picked a good country. People didn’t panic; they tried to help each other. Cooperation within the building increased. People took it upon themselves to manually direct traffic to prevent accidents without traffic lights.
- Until there are facts about the causes of the power outage in Spain, all channels promoting some version of their own are just propagandists. I stop trusting those where I see guesswork being used to promote their ideology.
- Reposted by Andrey SitnikY’all experiencing a multi-national crisis in Spain instead of the US was wild. People didn’t hoard groceries or water. No one looted or stole from unprotected businesses. Most places gave discounts on food. Neighbors checked in on each other. It was beautiful to witness that community care.

- I found out on Mastodon that the EU is planning to require tech manufacturers to clearly state how repairable their devices are. The situation with disposable electronics has really gotten out of hand. infosec.exchange/@jrt/1144029...

- Bought for my Framework laptop a third-party USB-A extension card with built-in Logitech receiver inside. To use a mouse without a receiver on the side. Even with semi-transparent plastic! People sell it on Etsy, based on the open-source design by LeoDJ www.etsy.com/listing/1709...

- Income should grow in line with labor productivity thanks to automation. But since the 1970s, workers' income has stagnated while productivity continues to rise. A very good question for our society: where are the new resources from automation going (like LLM)?
- Software companies should stop using resumes as the primary filter. Ask candidates to show real code. That will quickly narrow down the pool (it takes us just 5 minutes for the first stage). Or ask them to tell the story of the toughest problem they’ve solved.
- An interesting scientific study on how to organize effective collaborative discussions for large groups of people (and avoid those horribly inefficient 20+ person calls) inspired by the collective intelligence of fish schools. www.youtube.com/watch?v=_CJn...
- Attacks on vibe-coding have begun. LLMs sometimes hallucinate and install non-existent packages. As a result, attackers have started publishing malicious packages under these hallucinated names, which frequently appear in AI-generated suggestions. socket.dev/blog/slopsqu...
- Just finished the first season of Pantheon and it’s really cool. I can recommend it as another example of the emerging genre of dark transhumanism. The series is an adaptation of a book about what might happen to our society after the creation of mind uploading.

- A lots of memes claiming Europe is only good at regulations. But that just shows a lack of understanding of industry. Europe has plenty of problems and fair criticism. But without Dutch ASML, there’d be no M1 chips. And BioNTech, behind the RNA vaccine revolution, is German.

- Framework, the company behind modular laptops, released a kid-friendly model—affordable, rugged, easy to repair, and supports stylus note-taking. I think it’s important for kids to grow up in an open tech culture, instead of getting used to closed ecosystems. youtu.be/Ejl-7X74tgc

- Highly recommend to hire if you are looking a designer. Roman created the whole design department in our company, made it into the most well-organized division we have and while keeping pushing industry forward with OKLCH. He was also behind oklch.com design.
- Reposted by Andrey SitnikThis release includes long-awaited "--silent=passed-only" option, that can be used to hide console.log calls from passing tests. Only the logs from failing tests are reported.
- It’s not only Framework making devices easy to repair. For example, Supernote’s e-ink tablets have a cool special repair-friendly design. It’s great to finally see this trend in the industry. www.youtube.com/watch?v=LPAe...
