Excited to share HorizonDB - a Rust-based forward & reverse geocoder I built at Radar.

🚀 ~20k QPS steady state
⚡ Replaced multiple Elasticsearch & MongoDB instances
💡 Now a single Rust binary that’s faster, simpler, & cheaper

@vitruvian_form app is bricked due to a DNS issue - I'm very disappointed there is no way to use this expensive machine local-only.

For a search company, Gmail is _really_ bad at search.

@GergelyOrosz @SamProgramiz For most applications, you also get a bigger bang for your buck writing integration and acceptance tests than unit tests. It's also common to forget that even tests themselves introduce a maintenance cost like any other code.

@emacsbrah @mitchellh They have CDKTF now, which we've been happily using at @radarlabs in the TypeScript flavor

Trough of sorrow

[Jeff Kao @j_ckao]

@Splice why implement a "credits" system on your users if they can't even keep samples after spending those credits we paid for?

It should be all-you-can-download if you're charging a monthly subscription.

So shady, I guess business isn't so hot.

@bernhardsson It's great and low risk for ETLing our Mongo database exports to our data lake. Mongo export (JSON) -> DuckDB (Parquet) -> S3

@fullcrate Google Fi, my dude. Data works all over the world!

@aaronmblevin Not sure if I should be excited or terrified when the drop comes on this track.
