    HowToLiveBetter

    HowToLiveBetter

    Evidence-based living guidelines sorted by cost-effectiveness

    HowToLiveBetter is an evidence-focused interactive life guide that organizes hundreds of practical recommendations by cost, expected benefit, and strength of evidence. It covers health, longevity, emergency response, personal finance, legal risks, unemployment, entrepreneurship, relationships, parenting, travel, and skill development. Each recommendation explains what resources it costs and what outcome it is intended to improve. Evidence ratings are tied to journal research and official documents rather than general web commentary. The web interface lets readers search and filter recommendations by dimensions such as money, time, and required effort. The repository also includes longer essays, reference material, verification notes, and structured book chapters. It functions as both a static publication and a searchable decision-support reference.

    Iosevka

    Versatile typeface for code, from code

    Iosevka is an open-source, sans-serif + slab-serif, monospace + quasi‑proportional typeface family, designed for writing code, using in terminals, and preparing technical documents. The Iosevka’s monospace family is provided in a slender outfit by default: glyphs are exactly 1/2em wide. Compared to the competitors, you could fit more columns within the same screen width. Iosevka provides two widths, Normal and Extended. If you prefer more breeze between the character, choose Extended and enjoy. Terminal emulators have a stricter compatibility requirements for fonts. Therefore, Iosevka and Iosevka Slab all contain two specialized families, Term and Fixed, targeting terminal users. In these families, the symbols will be narrower to follow terminals’ ideology of column count. In the Fixed families, the ligation will be disabled to ensure better compatibility in certain environments.

    three.js

    three.js

    JavaScript 3D library

    three.js is a lightweight and easy-to-use JavaScript 3D library with its own default WebGL renderer. It works by creating a scene with a camera and a geometric cube, the latter of which is added to the scene. This will become the animated object within the scene. A WebGL renderer is created for the scene and the camera, with an added viewport to the document.body element. Finally, the cube is animated within the scene for the camera. A plethora of examples can be found in the project’s website (https://threejs.org/) which use Canvas 2D, SVG and CSS3D renderers that the library also provides.

    Bootstrap Icons

    Bootstrap Icons

    Open source SVG icon library for Bootstrap

    Free, high-quality, open-source icon library with over 1,600 icons. Include them any way you like, SVGs, SVG sprite, or web fonts. Use them with or without Bootstrap in any project. Bootstrap Icons are published to npm, but they can also be manually downloaded if needed. Bootstrap Icons are SVGs, so you can include them into your HTML in a few ways depending on how your project is setup. We recommend using a width: 1em (and optionally height: 1em) for easy resizing via font-size. Embed your icons within the HTML of your page (as opposed to an external image file). Here we’ve used a custom width and height. Use the SVG sprite to insert any icon through the <use> element. Use the icon’s filename as the fragment identifier (e.g., toggles is #toggles). SVG sprites allow you to reference an external file similar to an <img> element, but with the power of currentColor for easy theming.

    Tailwind CSS

    Tailwind CSS

    A utility-first CSS framework for rapid UI development

    Rapidly build modern websites without ever leaving your HTML. A utility-first CSS framework packed with classes like flex, pt-4, text-center and rotate-90 that can be composed to build any design, directly in your markup. Utility classes help you work within the constraints of a system instead of littering your stylesheets with arbitrary values. They make it easy to be consistent with color choices, spacing, typography, shadows, and everything else that makes up a well-engineered design system. Because Tailwind is so low-level, it never encourages you to design the same site twice. Even with the same color palette and sizing scale, it's easy to build the same component with a completely different look in the next project. Tailwind automatically removes all unused CSS when building for production, which means your final CSS bundle is the smallest it could possibly be. In fact, most Tailwind projects ship less than 10kB of CSS to the client.

    Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point.
