These new solid-state ACs promise a cool future. Scientists aren’t so sure.

After three years of record-­breaking heat, this one is set to be yet another scorcher. Air-conditioning? Not going anywhere. The International Energy Agency projects that the number of AC units will triple by 2050. That’s good for health—one Lancet study estimated that AC prevented nearly 200,000 premature deaths in 2019 alone—but bad for the planet.…

Reflection architectural pattern

Building software that can change itself without needing to be recompiled is a hard problem, and the reflection architectural pattern is a solid answer to that. I published an article diving into the reflection architectural pattern. If you've ever wondered how Spring Boot uses annotations to magically wire your dependencies, or how ORMs map database fields without explicit code, reflection is the answer. I break down how this pattern actually works, show practical examples, and discuss when you should and shouldn't use it. submitted by /u/Netunodev [link] [留言]

Local-first SaaS is trending, but the sync headaches are a trap

Everyone is hyping up local-first architecture because of Linear’s speed and the flack Notion is getting for its half-baked offline mode. Keeping data on the client sounds amazing for UX, but the engineering trade-offs are brutal. Unless your users are literally working in tunnels or you have strict privacy requirements, local-first feels like a massive over-engineering trap. Managing CRDTs, conflict resolution, and running database schema migrations across thousands of fragmented user devices is an absolute nightmare. Notion's struggles proved that trying to bolt offline support onto a legacy cloud-first DB just doesn't work well. I wrote a deeper breakdown on the strategic trade-offs and what the sync problem actually costs to solve here: https://buildmvpfast.com/blog/local-first-saas-offline-first-vs-cloud-first For most apps, a boring Postgres stack lets you ship fast and validate the product. You can worry about complex sync layers later. For anyone who has shipped a production local-first app, was the snappy UI worth the infrastructure headache? I'd love to get some feedback and hear your war stories on this. submitted by /u/Timely-Ad-2615 [link] [留言]

The UK is the latest country to follow Australia in implementing a total social media ban for children under 16, Prime Minister Keir Starmer has announced. The ban, which could take effect from early next year, will be joined by wider measures that will also prevent children from talking to strangers in online games, livestreaming, […]
