    Document verification can be difficult or impossible without trusting a third party with your files. Daniel G. has developed a way to prove a document existed at a specific point in time. The proof is created on the blockchain using a cryptographic fingerprint. The document itself never leaves your device and the hash reveals nothing about the content.

    Single-activity architecture simplified our Android app early on, but at scale it caused deep-linking, memory, and modularity issues; a hybrid, multi-activity approach proved more resilient.

  • TDD Is Backwards: Why Assertions Should Come First in Disruptive Development

    This story was originally published on HackerNoon at: https://hackernoon.com/tdd-is-backwards-why-assertions-should-come-first-in-disruptive-development.


    Struggling with TDD in chaotic projects? Stop starting with the setup. Flip the script and write your Assertions first to create executable specifications.

    When requirements are unclear, traditional TDD stalls at setup. By reversing Arrange-Act-Assert and starting with the assertion, developers can clarify intent, design cleaner APIs, and let tests drive architecture—even in chaotic projects.

    In regulated deep-tech, people argue about paper vs. 3D models, spreadsheets vs. metadata report, PDFs vs. PLM. That argument misses the point. Regulators don’t want paper. They want proof with properties that survive scrutiny.

  • Rust 1.77 and 1.78: The Changes That Happened to u128/i128

    Rust has long had an inconsistency with C regarding the alignment of 128-bit integers. This problem has recently been resolved, but the fix comes with some effects that are worth being aware of. As a user, you most likely do not need to worry about these changes unless you are. Ignoring the `improper_ctypes*` lints and using these types in FFI.

    The DOM is single-threaded, but modern web apps demand parallelism. This article breaks down practical multithreaded rendering strategies—Web Workers, SharedArrayBuffer, Offscreen Canvas, server-side DOM creation, and parallel DOM approaches—highlighting where each works, where it fails, and how frontend engineers can combine them to push performance beyond main-thread limits.
