Fast code, faster markets — built with Rust, the Sajbeni way.

🦀📐 Building a Linear Algebra Engine in Rust — Part 1

Most modern machine learning libraries (TensorFlow, PyTorch, etc.) embed telemetry and hidden behaviors. LinearAlgebra-WS is different — it's completely open, simple, transparent, and under your full control. No tracking. No hidden code. Just math.

Beyond Frameworks, No Shortcuts
Everyone can import. Few can build. Let's change that.

  • Vector Operations
    • Sum
    • Subtraction
    • Multiplication (element-wise)
    • Division (element-wise)

    🦀 How High-Frequency Trading strategies detect inefficiencies in the currency market

    In FX, milliseconds can create profitable opportunities. This post breaks down the math behind currency arbitrage — and simulates it using pure Rust (no external crates, just threads and channels). Here’s the logic traders use to act faster than the market itself.

    📉 What Is Currency Arbitrage?
    Let’s consider a realistic example:

    Spot Dollar (cash market): R$5.00
    Futures Dollar (near maturity): R$5.05
