Show HN: I built a small utility that handles multiple browser instances for you https://bit.ly/3W83S5Y

Show HN: I built a small utility that handles multiple browser instances for you I'm a consultant and I normally deal with multiple clients. I need an isolated browser for each to maintain my sanity. I could create separate profiles in Chrome and Firefox but the main issue is when you click on a link outside of the browser (e.g. in your IDE), in which profile should it be opened? I wrote a Python script that redirects URLs to the correct browser instance and set it as my default browser. Over time, the script has grown and become essential to my work. I cleaned it up and open-sourced it. Hope that someone else may find it useful too! https://bit.ly/3Jtmrdi April 20, 2024 at 02:03AM

Show HN: Composable (as in iGoogle, but modern) privacy-friendly new tab https://bit.ly/4b1GNpx

Show HN: Composable (as in iGoogle, but modern) privacy-friendly new tab I spent quite a lot of time working on this one over the last 1.5 years. It started as a small project for my personal use because I wanted to keep all my self-hosted services visible so I wouldn't forget they existed lol. Using a web page wasn't ideal because of the white flicker every time I opened a new tab, so I decided to make this into a browser extension. From that time on, it became a lot bigger and got some traction (which I'm very happy about). It's made with React, but I tried to squeeze maximum performance (limited by my skills and desire to keep it somewhat readable, though) out of it. UI/UX was a big priority for me in this project, so I also tried to streamline it as much as possible and make Anori a joy to use. If you decide to try it, let me know how good I did! Oh, and it's open source [1] and the process of adding new widgets is documented [2], so you can make your own!

Show HN: An app that takes your money if you don't reach your goals https://bit.ly/3vWHbXE

Show HN: An app that takes your money if you don't reach your goals My wife and I just launched this app because we had so much fun with a fitness challenge we did we some friends recently where everyone put in $100 and defined their goals, then only the people who met their goals split the pot. It made us realize there's really no better motivator than money. It's better on mobile screens right now as we just designed for mobile screens for now. And we did manage to put it up on both app stores - it's low in the ranks but you should be able to search it by "Goalie challenges". We built it using the leanest tech stack - Ruby on Rails, server-side HTML (no JS), tailwindcss, then packaging it for iOS and Android using pwabuilder! https://bit.ly/4b1cZJS April 19, 2024 at 12:02AM

Show HN: I made a custom cursor builder in 1 week https://bit.ly/4448dIZ

Show HN: I made a custom cursor builder in 1 week Hi HN, Over the past week, I've been developing Cursumber, a tool designed to help you easily create and integrate unique cursors into your website. Today marks the soft launch of this platform, and I'm eager to gather community feedback and gauge market interest. Features of Cursumber: Upload and Customize: Select or upload your cursor images (supports PNG, JPG). Preview in Real-Time: Test how your cursor looks and functions on your site before going live. Easy Integration: Simply copy the provided JavaScript script and paste it into your website's code. Community Building: (Planned) Future plans include creating a community space where users can share and discuss their custom cursor designs. Cursumber aims to add a layer of identity and uniqueness to your projects with minimal effort. I've put a lot of work into making this tool user-friendly and would really appreciate your feedback and suggestions. Thanks for checking it out—I'm looking forward to hearing what you think! https://bit.ly/3TYWYx3 April 17, 2024 at 08:45AM

Show HN: Privacy Manifest CLI tool for iOS apps https://bit.ly/4d3bvjS

Show HN: Privacy Manifest CLI tool for iOS apps I have created a simple CLI tool to help me go through the codebase of my iOS apps and detect those 'required reason' APIs and SDKs that Apple now requires developers to disclose on a separate manifest file. I have also added the option to generate a simple Privacy Manifest file based on the findings and on the responses that the developer will give. Even though it's a bit too niche for HN, there maybe iOS devs here that might find this tool useful! https://bit.ly/4d3MdlV April 17, 2024 at 08:00AM

Show HN: Building a GPS receiver https://bit.ly/49LyflS

Show HN: Building a GPS receiver Hi everyone! Shortly after publishing my iOS 4 jailbreak last October[1], I got to work on my next hobby project: a from-scratch homebrew GPS receiver, which can solve the user’s location solely from billions of radio antenna samples. I took a commodity SDR (alongside the Python standard library and numpy) and built a signal processing pipeline that can detect and track GPS satellites over many minutes, drop and pick up satellites as they come in and out of view, and precisely determine the user’s position and clock inaccuracy. All told, gypsum can go from a cold start to a fix on the user’s position, and the precise time, in less than a minute of listening to the antenna. I went on a journey of learning how to detect and track satellite signals that are literally too quiet to hear, and I hope that some of the magic comes through in the posts! After implementing this myself and walking the long road of getting it working, I’m left completely stunned by the brilliance of GPS, across so many axes. I hope you enjoy the read! On a more personal note, I’ll be starting a new job next week which isn’t as amenable to publishing side projects, and therefore this will be my last publicly-published project for some time. I’ve had great experiences making and sharing projects on here, and I’m really grateful for the positive feedback that’s been shared!

Show HN: GPU price-per-hour tracker for A100/H100s Out of curiosity, I put together a simple website which tracks the prices for a few variations of A100/H100 GPUs by hour broken out between spot/ondemand, form factor and provider. Specifically I was tailoring the tool towards the smaller, emerging providers like runpod, gpulist.ai, lambda labs etc. Anyone have any ideas to expand/refine it? https://bit.ly/3JinAEf April 13, 2024 at 08:08PM
