  5. KeeWeb

    Free cross-platform password manager compatible with KeePass

    Project mention: Bitwarden SDK relicensed from proprietary to GPLv3 | news.ycombinator.com | 2024-10-24

    It is actually sort of how I used it as well, though through nextcloud. It did still remain a hassle. It also requires all different apps to be maintained and equally safe.

    Keeweb for example has not had an active maintainer since 2022 https://github.com/keeweb/keeweb/issues/2022

  6. to-markdown

  12. staticrypt

    Project mention: Password protect a static HTML page, decrypted in-browser in JavaScript | news.ycombinator.com | 2024-08-30

    Especially with 600k PDBKF2 iterations, 16 alphanum chars should be very safe.

    There's a (warning: very detailed) issue covering the topic of PBKDF2 iterations and password length over here, if you feel like diving into that rabbit hole: https://github.com/robinmoisson/staticrypt/issues/159

  13. preline

    Preline UI is an open-source set of prebuilt UI components based on the utility-first Tailwind CSS framework.

  14. wpt

    Test suites for Web platform specs β€” including WHATWG, W3C, and others

    Project mention: WebShield – A new wide-spectrum content blocker for Safari | news.ycombinator.com | 2025-02-28

    Blink forked from Webkit more than a decade ago. There are tests that try to measure their compatibility, like https://wpt.fyi/results/?label=experimental&label=master&ali... (part of https://web-platform-tests.org/). They also have different JS engines these days (V8 vs JSCore).

    That said, as a frontend dev, I very very rarely run into real world issues between Safari and Chrome. More often it's Firefox/Gecko that lags behind, usually in some sort of graphics optimization (SVG and canvas stuff). Also some differences in WebGL and webgpu support, but those are niche enough that it's not a big deal yet.

  15. intercooler-js

    Making AJAX as easy as anchor tags

    Project mention: How do you do, fellow web developers? A growing disconnect | news.ycombinator.com | 2024-12-19

    regardless of what CSS query you use to look the element up, in the jquery example you'd still have your logic (the url, etc) defined elsewhere

    the htmx version is symmetric with the href attribute in that it completely specifies what is going to happen directly on the element itself

    of course you could do something in jquery like using a data attribute to store the url and HTTP method, etc, but at that point you'd be building https://intercoolerjs.org, the predecessor to htmx

  16. supercookie

    ⚠️ Browser fingerprinting via favicon!

    Project mention: Simple Browser Tracking | dev.to | 2025-05-03

    Tracking users is a touchy topic. Should you rely on screen size? Favicon loading hacks (like this one)? Or something more exotic?

  17. BotBuilder-Samples

    Welcome to the Bot Framework samples repository. Here you will find task-focused samples in C#, JavaScript/TypeScript, and Python to help you get started with the Bot Framework SDK!

    Project mention: Building a Microsoft Teams Bot App – Step-by-Step Setup Guide [Part I] | dev.to | 2024-09-08

    Download a simple echo bot (written in nodejs) from the sample here. This bot just responds with the same user message as received.
