Ask HN: What is the most impactful thing you've ever built?
I've created a knapsack ruby gem for CI parallelisation that has over 122 million downloads. Primarily due to the fact, Gitlab is using it.
I spin off https://knapsackpro.com from the knapsack gem and we are helping our customers run fast CI builds.
- Run 1 hour test suite in 2 min with optimal parallelisation on existing CI infra

With some posts about sightings this year in Brisbane, be on the lookout for these Christmas Beetle imposters (how to spot the difference and where to report sitings of Christmas Beetles)
You can submit sitings of Christmas Beetles here https://www.inaturalist.org/ or on the iNaturalist app

Opinions on AI Plant Identification?
Personally, I like iNaturalist for identiying wild organisms. The AI is well-trained and based on a regularly-updated taxonomic structure from established authorities. The ID suggestions incorporate the location of the observation to suggest species that are known to be found nearby. And most crucially, when observations are posted they're available for other humans to confirm or refute any ID suggestions that come from the AI. The AI suggestion is only ever the start of the identification process.

How I overcame my anxiety of possibly getting bit by a rabid bat
Search up the smallest bat in your area and browse photos of them at iNaturalist: https://www.inaturalist.org/
- WTF are these
- does anyone know what kind of spiders inhabit the bridges/river walk?
- Newly found interest in fungi and looking for help identifying these finds from my yard.

Hey guys, you can use the inaturalist app to identify plants!
You can also just upload the pictures onto the website.

Question on species of a toad and or frog not entirely sure but the little dude was bumpy and seemingly dry
You could try getting the iNaturalist app to ID it
