Show HN: hcker.news – an ergonomic, timeline-based Hacker News front page
22 by postalcoder | 8 comments on Hacker News.
Hi folks, I've built an alternative Hacker News front page. It is inspired by and meant to be a replacement for hckrnews.com. I built this because HN is woefully underfeatured, but most sites that try to improve it seem to assume that the visual design is the problem. hcker.news tries to maintain HN's familiarity while adding useful enhancements. There are three primary views: - Timeline View: Browse top stories by votes or comments grouped by day, week, or month (e.g., top 20 per day, top 100 per week). - Aggregate View: See top stories by votes or comments over custom time ranges. - Front Page View: The original HN front page, untouched. Feed Filtering: - Custom Keyword Filters: Include/exclude keywords (e.g., include "Rust," exclude "DOGE") or set a minimum score threshold. - No HN Algorithm: Timeline and Aggregate Views show stories usually downranked by the HN algo (e.g., flagged posts or those with too many comments). UI: - Unread Flags: Quickly spot new stories or ones you haven't seen. - Two Layouts: Classic HN style or a compact story view inspired by hckrnews.com. - Multi-column & High-density Modes: Fit more content on screen. - Themes: Light, Dark, and Manila. I'd love your feedback and suggestions. Cheers!

Show HN: DoubleMemory – more efficient local-first read-it-later app
12 by randomor | 1 comments on Hacker News.
DoubleMemory started as an experiment to see if I can somehow automatically save all double cmd + c, as I often do instinctively, so I don't need extensions to save links and text into an app, and avoiding flooding the capture history as regular clipboard managers does. My motivation was not to create a read-it-later app, yet it evolved into this unique yet cohesive form of a read-it-later + bookmarking organizer + clipboard manager + card based note-taking app over the last 6 months. It also launches from the menu bar with a shortcut and navigates with keyboard shortcuts. My favorite part is instead of rendering a list of article titles, everything is rendered as pretty preview cards in a translucent Pinterest-like mood board. It also has a nifty iOS app, that will allow you to swipe with your thumbs between articles just like on iOS Safari... Now that Pocket is closing, this is after Instapaper going back to indie and Omnivore and UpNext and numerous others closing over the years. All of these are cloud-hosted services, which got me reflecting: maybe this local-first architecture would be well positioned to build in this space. Here is my not-so-scientific comparison: ## Domain $10 vs $1M = 100,000x difference. ## Server running cost No servers other than what's running by iCloud vs $1M per year = 1mX difference ## Platforms Apple only (mac + iphone + ipad) vs Multi platforms (windows, linux, android also supported) = 20X maintenance cost difference ## Capturing No browser extensions required v.s. maintain all extensions for various browsers and extension stores = 5x difference ## Architecture App receives the link, Apple generates the rich preview cards for thousands of different types of links, app caches these preview cards. vs.Someone write some custom code for each link type or with Open Graph, one designer created one generic card that works for all links.=100x cost difference. I know, Apple is coming for clipboards with more restrictions, which is basically a shared global state on Mac systems, DoubleMemory does also support other ways to capture: drag-n-drop to app/menubar icon/app icon, right click->Services menu, or Share sheet. We will add more auto-importers. Also vibe coded some importers for Pocket, Omnivore and ReadWise here: https://ift.tt/zDy9MQ8 Everything in the app is free with no limits. Capturing is really step 0. You giving us a chance to save your content, doesn't mean you are getting any values out of it (ain't that the typical story of read-it-later apps? save-it and never-read-it). the eventual goal is to easily retrieve these content, and eventually consuming them. I hope to eventually launch paid features that aligns with these value generating workflows. App Store link: https://ift.tt/o0FgPXh Let me know what you think...

Show HN: GetStack.dev – Track GitHub open-source trends
11 by h1fra | 3 comments on Hacker News.
Hi HN! I’ve been working on getstack.dev[1], a tool to help developers track GitHub open-source trends, tech adoption, and repository stacks — updated weekly. About a month ago, I broke my leg. While stuck on the couch, I figured I’d put the downtime to good use and finally build a side project I’d been thinking about for a while. So I put together an MVP and decided to release it publicly to gather feedback. I have always struggle to grasp how people are adopting technology and what's really hype or under the radar. As tech leader you also often want to know if your tech choices are the right one but it's hard to take a data driven solution. And as open-source lover I always want to know how my favorite projects are built. All the data is pulled and refreshed weekly from GitHub, stored on ClickHouse [2] but you can directly check how I built it in the website [3] [1] https://getstack.dev [2] https://ift.tt/WBRNVPU [3] https://ift.tt/eyBmivu

Show HN: HNRelevant – Add a "related" section to Hacker News
12 by imadj | 1 comments on Hacker News.
It's been 2 years since the initial release [here]( https://ift.tt/ArSjTRL ). The initial version was a very basic prototype which was not available anywhere beyond the GitHub repo. You had to install it as a userscript or load the extension manually. Since then, it remained simple but better, new features include: - Improved accuracy by also using comments to help gauge the topic of discussion and the right keywords. - Published as plugin for more browsers: Chrome, Firefox (including android), and more recently Microsoft Edge. - Support for narrow screens and mobile devices. - Added preference controls. You're here because you love interesting HN discussions but they're often buried away like hidden gems, so give it a try and let me know what you think.
