New top story on Hacker News: Show HN: Supapool – a Supabase per coding agent in ~400 ms

Show HN: Supapool – a Supabase per coding agent in ~400 ms 6 by kevo1ution | 0 comments on Hacker News. hi HN, I built supapool.io, an ephemeral full copy of supabase's services that you can spin up in ~400 ms (Auth, postgres, storage, realtime). so if you run multiple coding agents in parallel in different worktrees, they can now have their own copy of supabase without making changes that conflict with eachother. > why not use supabase docker locally? when I run 3-4 instances locally, my macbook gets hot and sometimes freezes. > why not use supabase branches? branches take minutes to setup, and are designed for persistence. this is expensive, and for a dev environment, it is too slow. > why not use mocks? mocks are bad for agents. i expect agents to test their migrations, SQL against real prod service behavior. agents hallucinate working mocks often. However, upside of mocks is that its faster and runs locally, but with supapool, the upside is less convincing. > how...

New top story on Hacker News: Show HN: CheapFoodMap – A map of good meals under $10

Show HN: CheapFoodMap – A map of good meals under $10 17 by jaep1 | 16 comments on Hacker News. I was recently laid off after 18 years, and gave myself 100 days to build soething useful in public. CheapFoodMap is a crowdsourced map of meal under $10, excluding franchises, local good eats only. It's inspried by 거지맵 (Begger's Map) a Korean crowdsourced map students use to find cheap eats. Ocverage is heaviest in Texas, since I live in Dallas, but have 1200 meals across 15 US cities. Seed data came from Google Review, 4.2 star or higher with at least 500 reviews, and verified price under $10 per menu item. Things I would love feedback on : whether the price-freshness model makes sense, and what would make you trust the price on a site like this. How to encourage people to update prices, since inflation is making food price very frequent. https://ift.tt/7sHgEfQ Any and all suggestion will be super helpful. Thank you!

New top story on Hacker News: Show HN: Brolly, a plain-text weather forecast site

Show HN: Brolly, a plain-text weather forecast site 6 by jsax | 0 comments on Hacker News. The UK MET office recently redesigned their site, adding a lot of additional whitespace, scrolling, and animations. This significantly reduced its usability for me, and left me wanting an ‘at a glance’ weather site. I made https://brolly.sh , a minimalist, plain text weather forecasting site. You can use it to view weather from around the world, with: 7 day forecast; Previous day log (so you can confirm it definitely was cooler / hotter / wetter / drier yesterday!); Hourly rain, wind, temperature, conditions; Hourly UV, air quality and pollen, including pollen type specific forecasts within the EU / UK; Location search and last 5 locations; Location specific units. I mostly made the site for myself, if anyone else also benefits from it that’s an added advantage. You can check out the weather in York, UK at https://ift.tt/abwESQO , or search for a location at https://brolly.sh The site is d...

New top story on Hacker News: Show HN: I made some transistor animations

Show HN: I made some transistor animations 3 by stunningllama | 0 comments on Hacker News. Hi HN, I made some animations of the most important kinds of transistors using my semiconductor simulation, details of which are on the page. I tried to make the visuals as realistic as possible while also aiming for clarity. If you want to go beyond the charge carriers and look at, for example, the electric field, you can do so in the simulation software. The desktop software also has less common devices like IBGTs and SCRs that have similar animations. The last thread about my software was posted here about a year ago: https://ift.tt/RMEUFpr
