I’m working on https://www.zonehero.io/ to deliver a cost effective alternative to AWS native load balancing (ALB).

We already had a PoC which saved our customer 50% vs ALB (in their case that’s more than a million dollars a year), we’re now working on tooling and scaling the solution up!

Next we want to bring wasm modules to the lbs, to do edge traffic curation, bring your own model, etc.

In technical terms, we offer a fully managed control plane for an optimised version of envoy running on EC2, and we react in near real time to avoid unnecessary cross AZ traffic (the key to the costs savings).

I've been curious about doing algotrading for both the data engineering aspect and the quant. Do you have suggestions about books or others sources to get inspiration from ?

Is this a one man venture or do you have a group discussing edges ?

Hey guys! We're engineers/designers from France, and we've built the Ultimate DIY Battery that you can repair and refill! - Ride Sustainably with the World's First Repairable Battery - Refillable in 5 minutes (just buy $150 worth of new cells every 3 years or so, when they're depleted) - Be Worry-Free thanks to the Fireproof Casing! There's been waaaaaay too many lithium fires! It's launching as an IndieGogo in one w…

btw do you plan to leverage your pcb connector plates for other kinds of batteries ?

If so good why are you selling it as a service ?

Open source doorbell camera software running on Raspberry Pi Zero. Face recognition and motion detection already built-in, so I've set it up so that I get a message on element when someone is at the door and a video of any motion longer than 5 seconds. Not fully optimized yet.

I‘m building https://sql-workbench.com in my spare time.

It‘s a SQL Workbench in the browser, based on DuckDB WASM. You can query remote and local datasources, such as CSV, JSON or Parquet files.

You can also visualize the results, and share the queries via URL. Let me know what you think!

I'm working on a 2D computational geometry library with a focus on irregular part packing in Rust. IE laying out laser cuts for wood or water jet for metal. https://crates.io/crates/babushka

I've got some nice types set up and a no fit polygon algorithm. Working on the genetic algorithm for packing à là svgnest.
