This is an awesome use of MCP. Thank you!

Ok, in over a decade on HN I've never commented on a product but this one is awesome! I just signed up!

I currently pay $99 a month to learn Spanish from a live tutor 30 mins a day, and this is far superior if you ask me.

The element that stands out to me is that the AI Tutor is consistent and concise!

I spent three months in El Salvador before the Bitcoin Legal Tender law passed, then another three months after it was enacted.

From day one, I knew it wasn’t going to work.

That’s when I flew back to Miami, went back to the drawing board, and stopped being a Bitcoin maxi.

Great stuff! I really liked your Elixir/Crypto course. Please update it

Algo Traders Club: TypeScript joins Python and Rust for full-stack DeFi development on Solana. Discusses advantages of language-specific strengths - TypeScript for cross-stack type safety and UI, Python for data/ML, Rust for on-chain performance. Argues for pragmatic language choices in DeFi: using TypeScript's native Solana SDK integration + UI capabilities for hackathons, Python for analysis/ML, Rust for high-performance contracts. No ideological language wars, just tools for jobs. Includes practical comparisons and implementation resources. Relevant for builders interested in:

We launched Algo Traders Club building DeFi trading bots in Rust on Solana. After feedback from our West African developer community, we're strategically switching to Python while keeping Rust for performance-critical components. This decision reflects both technical and market realities: Python dominates the data science and ML landscape in the region, with communities like GalsenAI in Senegal already doing sophisticated ML work. Python's lower barrier to entry and rich quantitative libraries make it ideal for trading strategy development, while wrapped Rust modules handle low-level blockchain operations. Our goal is to leverage existing Python expertise in West Africa to democratize access to permissionless DeFi trading opportunities.

A technical deep-dive into Solana's Raydium AMM architecture, explaining how it improves upon traditional banking exchanges through OpenBook integration and constant product formulas. Includes code examples in Rust showing actual account structures, transaction flows, and price impact calculations. Built from examining Raydium's open source CPI (Cross-Program Invocation) implementation.

Solana liquidity pools are an elegant application of constant product market maker formulas running at 400ms block times. This technical primer breaks down how they work, from basic token swap mathematics to Rust implementation examples. We explore how these automated markets eliminate traditional finance intermediaries through smart contracts, discuss their underlying mathematical principles, and examine the emergence of concentrated liquidity positions. Written for developers interested in DeFi mechanics, with code samples you can run yourself.
