  • When “Five Minutes” Becomes a Requirement

    This story was originally published on HackerNoon at: https://hackernoon.com/when-five-minutes-becomes-a-requirement.


    Why precise requirements can be misleading when the underlying evidence is approximate, and how to trace a number back to its real basis.

    OOP is a way of managing software complexity by giving objects clear responsibilities, protecting their state, and defining how they interact. This guide covers classes, objects, encapsulation, abstraction, inheritance, polymorphism, composition, coupling, cohesion, and common design mistakes—with practical examples of how these concepts work together to create cleaner, more maintainable systems.

  • Firefox Didn’t Just Lose the Browser War. Mozilla Slowly Gave It Away

    This story was originally published on HackerNoon at: https://hackernoon.com/firefox-didnt-just-lose-the-browser-war-mozilla-slowly-gave-it-away.


    I did not quit Firefox in one day. Brave was my backup until it became my default. This is how Mozilla slowly lost me.

    I never decided to leave Firefox. Brave was only my backup for testing and for sites that acted weird, then slowly it became the browser I opened first. No single crash, just years of small stuff piling up. Late features, the extension break in 57, redesigns nobody asked for, plus Looking Glass, Cliqz and the Terms of Use mess. Chrome set the trap, but Mozilla kept giving me reasons to stay away.
