    Greg Isenberg: VC funding works for less than 1% of companies. Here's the actual math.

    This is a community discussion on r/artificial sharing Greg Isenberg's argument that venture capital fits a tiny fraction of companies, making alternative funding paths the norm rather than the fallback. Isenberg and Derek Andersen present figures showing fewer than 1% of companies created receive VC backing, and of those funded, only a small fraction deliver meaningful returns, challenging the assumption that raising venture capital is the default path.

    SIMD for Collision

    This is an engineering blog post by the author of Box2D, a 2D physics engine, explaining how SIMD instructions are applied to collision detection. Building on a previous post about using graph coloring to speed up the contact solver, the article explores processing multiple collision work units simultaneously using vector instructions, aiming to improve the performance of broad-phase and narrow-phase collision routines.

    log is non-monotonic in PHP and Lua

    A practitioner-oriented blog post explains that the logarithm function can return non-monotonic results in PHP and Lua due to floating-point representation issues. The author demonstrates that larger input values can sometimes produce smaller outputs than preceding values, breaking the mathematical expectation that log(x) increases as x increases. This matters for developers relying on monotonicity invariants in sorting, indexing, or comparison logic.

    Slash Pages

    Slash Pages is a community guide cataloging common pages developers add to personal websites using standard root-level slugs such as /now, /about, and /uses. Each slug follows an informal convention where site owners share specific information—current activities, biographical details, or tools and equipment used. These pages are described as distinguishing characteristics of the IndieWeb movement.
