I built an open-source wallpaper gallery for GitHub repos

What it does

A beautiful wallpaper gallery showcasing wallpaper collections

In the maker’s words, at launch

Hey HN, GitHub has hundreds of wallpaper repositories with thousands of images, but actually browsing them is painful. You either clone gigabytes locally or click through the file browser one by one. So I built WALL·E Gallery. Use existing collections or Paste a repo URL→ instant gallery. How it works: - Fetches repo…

  Instantly create a GitHub repository to take screenshots of a web page2022 · simonwillison.net · ▲214

  I built a GitHub repository template which automates the process of configuring a new repository to take web page screenshots using GitHub Actions. You can try this out at https://github.com/simonw/shot-scraper-template Use the https://github.com/simonw/shot-scraper-template/generate interface to create a new repository using that template, and paste the URL that you want to take screenshots of in as the "description" field. The new repository will then configure itself using GitHub Actions, take the screenshot and save it back to the repo!

  RepoSweeper2024 · reposweeper.com · ▲57

  I built this in 2018 as a school project to bulk delete GitHub repos. It got 25k views on Medium and ~10k users organically, then I basically ignored it for years. Recently I dug into GitHub's community discussion board and some low hanging fruit for feature additions — archive, visibility changes, collaborator cleanup. GitHub's answer was always "use the API." So I built the UI. RepoSweeper now does: - Bulk archive / unarchive - Bulk visibility (public ↔ private) - Bulk collaborator add/remove - Staleness scoring so you know what to act on first - Handles 100+ repos with…

  I built a tool to try artworks on your own wall2024 · wallartlovers.com · ▲38

  Simply upload a photo of your wall, upload the artwork images, position them, and download the result. It's very lightweight and nothing is uploaded to a server - everything runs directly in your browser. Why I made this: Existing apps (like Artrooms) fell short for me because they only offered stock wall images and limited 3D positioning, especially if your wall isn't perfectly frontal. I wanted something more flexible that would allow me to experiment with more scenarios, even when the photo is taken at a weird angle. The objective is to get a feel of how'd it look like, without the result…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  22 GB of Hacker News in SQLite▲730

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
