    "Code to an interface" never made sense to me. I questioned the need to create an interface and then implement it. How do I determine when and where to use these interfaces? If you're experiencing this, know that we've all been there. Let's help you understand why you need to "Code to interface".

    The motivation for this approach is very simple, we want to reduce the amount of boilerplate code by creating universal tools. We will solve this problem in 4 stages. Writing an abstraction of the data type of scrolling elements; writing a base class for scrollable elements; Writing an Implementation for Lists; and Writing an implementation for Lists.

    Open source has evolved from a few pioneering transparent projects into the backbone of modern development across the industry. With a wide range of development practices and open-source licenses, the meaning of "open source" can vary significantly. I aim to explore the true value of openness and identify what is and isn't genuinely open.

    Duplicated code is a severe code smell; it leads to maintainability problems and ripple effects. Start by identifying behavior duplication. extract it into reusable functions or classes, reducing redundancy, creating a single source of truth, and simplifying future updates. Refactoring isn't a one-time event; it's an ongoing process.

    If your backend storage doesn't natively support spatial queries, this article is tailored for you. You can always build another microservice to handle spatial data, but this option often involves the overhead of maintaining an additional application. Another approach is to use geo-indexing libraries like S2 and H3. S2 divides the sphere into cells, each with a unique 64-bit identifier. Higher levels correspond to finer resolutions and smaller cell areas.

  • Temporary Lifetime Extension: Complicated Cases

    This story was originally published on HackerNoon at: https://hackernoon.com/temporary-lifetime-extension-complicated-cases.


    Software design is difficult. One has to design features to fit past and future code. C++ Temporary lifetime extension can teach us a lesson about such design.

    This article shows us two, at the first glance, distinct examples of c++ temporary lifetime extension (TLE) feature behavior. The one where we extend temporary lifetime through polymorphic reference conversion and the one where we do it through bounding a field of a temporary directly to a reference. However, if you look deeper you will see that in some context these two examples are similar. And therefore the feature behavior in both cases should be the same. The consistency is an important aspect of any design which helps users use the feature and temporary lifetime extension can show it on its own example.
