Layer проти Staffcoder, hands-on practice for modern frameworks in a browser IDE

One API for prediction markets. Find markets, stream normalized data, place orders, and track positions across Kalshi and Polymarket. Hi HN, I'm David. I built Layer, an API + SDK or building trading bots/ai agents across prediction markets.The idea came from something i kept running into while playing with trading bots. Once your bot needs access to more than 1 venue, you suddenly have to deal with different market schemas, contract definitions, prices, fees and APIs before you can reason about where to trade. That gets messy real fast, especially with prediction markets. The same real-world event can exist on Kalshi & Polymarket, but the contracts can be represented differently.Here's my broader thesis:...

Staffcoder helps developers build real-world engineering skills through hands-on framework practice and production-style challenges in a professional IDE. Hi HN,I'm Shashank. I have curated 1000s of practical real world software engineering assessments in the past as part of my job. I felt there's a gap where if a person wants to learn to build software they have many options to learn from (learning platforms and free resources) but very few or no options to practice their skills hands on. I built Staffcoder so that developers can learn the skills while solving real world scenarios across various domains in software engineering.On Staffcoder you can select a skill, start from beginner level and move up solving real world challenges.
