Show HN: TapTab – Tab switching web extension for Safari https://ift.tt/AqjLQgK

Show HN: TapTab – Tab switching web extension for Safari I like the tab-switching behaviour in Chrome/Firefox and wanted Safari to have something similar. Another wish of mine was for it to be a web extension that feels native to the browser vs an app extension that looks out of place. I posted a while back on HN to see if other people feel the same and the response was very positive : https://ift.tt/uEYi1Wx Say hello to TapTab : https://ift.tt/HATfFec... TapTab feels right at home in Safari and is loaded with features to improve how you interact with tabs. You no longer have to miss the native tab-switching functionality that you love in Chrome/Firefox. I launched the app a few days ago, and the response has been great. Some of the features that users have been loving : - Keep your hands at the keyboard: navigate all tabs without your hands leaving the keyboard. - Fuzzy Search: Search through your tab titles and URLs at lightning speed. - Switch to previous tab: Comes with a handy sho

Show HN: GUI-based free app to backup and restore hard disk on Windows clients https://ift.tt/6ak8iwc

Show HN: GUI-based free app to backup and restore hard disk on Windows clients I wrote a small GUI-based tool that uses the Windows Imaging Format (WIM) to create full backups of computer systems (operating system images) and then restore them. The application is hosted on GitHub, is open source, and is offered under the Apache 2.0 license. In addition, the repository includes an illustrated step-by-step guide to help get it up and running. Maybe someone can use the solution for their purposes as well - I would be happy. Have fun with it. The GitHub repository is named: WIM-Backup December 24, 2022 at 12:28PM

Show HN: Shmux – run all your scripts from one file https://ift.tt/f7SWUZb

Show HN: Shmux – run all your scripts from one file Hello all, This is a small, few hours Holiday project I made out of frustration on what I would have liked makefiles to be but are not. It's rough, but it might be useful for somebody. Any type of feedback is welcome! https://ift.tt/U1Xz9Rh December 25, 2022 at 12:06AM

Show HN: Digital privacy game for middle schoolers, our Harvard final project For our final project in CS105, Technology and Privacy, my friend and I made an educational game about digital privacy for middle schoolers! We'd love any feedback or suggestions. https://ift.tt/oQlzwra December 25, 2022 at 12:11AM

Show HN: Simple golinks server backed by airtable https://ift.tt/wOoyKu2

Show HN: Simple golinks server backed by airtable Like short codes? Like bookmarks? Have fun with this very simple golinks server. If you haven't heard of golinks, they are short codes to bookmarks. In your browser you type `go/ ` and it takes you to a bookmark. Eg, `go/hn` or `go hn` (space is easier to type than forward slash) could take you to https://news.ycombinator.com . Happy Holidays! https://github.com/skhavari/golinks December 24, 2022 at 05:03AM

Show HN: Search HN Favorites or Export to CSV/HTML https://ift.tt/7mZx3B8

Show HN: Search HN Favorites or Export to CSV/HTML I wrote a JavaScript tool to search your HN favorites and export them to CSV or HTML. The JavaScript runs in your browser like a browser extension. It scrapes the HTML and navigates from page to page. Setup and usage instructions are in the file. https://ift.tt/T91njSo December 24, 2022 at 03:07AM

Show HN: Box4D – 4D physics demo using Rust and wgpu https://ift.tt/yVfWOTN

Show HN: Box4D – 4D physics demo using Rust and wgpu This is a little physics toy I've been working on off and on for a while. I originally planned on making a more fully featured game of some sort (I suppose I still may some day), but it turns out that writing interesting graphics and physics algorithms is more compelling than the hard work of polishing an actual product. Who knew? While there are plenty of good guides for 2D and 3D graphics and physics, there's not much out there for 4D. In hopes of alleviating that, the code here is arranged such that the commits are more or less a step-by-step guide, with comments for the interesting or tricky parts. While I don't think I came close to the simplicity or clarity of Box2D Lite, I hope it can serve as a useful example to anyone interested in 4D rendering and physics. https://ift.tt/LgOyb08 December 24, 2022 at 12:30AM

Show HN: Teetty: a CLI tool to remote control a program running in a terminal https://ift.tt/Q7oYf40

Show HN: Teetty: a CLI tool to remote control a program running in a terminal I needed to remote control a program (and read it’s output) while that tool should still be fully interactive for the user. Obviously there are things like tmux and more but they emulate an entire terminal. This is simpler in that it just sets up a pty and basic pipes or files to send stuff in and read from it. https://ift.tt/ynFPChp December 23, 2022 at 07:13PM

Show HN: Metriport – Open-source universal API for health data https://ift.tt/2maeQq3

Show HN: Metriport – Open-source universal API for health data Hey HN, we’re Colin and Dima, founders of Metriport ( https://metriport.com/ ). We help digital health companies access and manage user health and medical data, through an open-source and universal API. Today we're launching our open-source Health Devices API, which allows companies to gain access to their users’ health data from various wearables, RPM devices, and mHealth apps. You can check out the public Github repo here: https://ift.tt/ezYoKPx For developers in the health data space, building integrations to various data sources is a huge pain, as it means wrangling different data formats, gaining access to the APIs in the first place, and ultimately spending precious developer resources building out data pipelines. We solve this pain for you through our open-source API, which is quick and easy to get started with (see: https://ift.tt/TgesPqb... ). Out of the box, our Health Devices API supports integrations with Fi

Show HN: Fully offline, open-source alternative to Scribe for Firefox https://ift.tt/rB4OwaA

Show HN: Fully offline, open-source alternative to Scribe for Firefox I had to do a bit of web-workflow documentation and found the process of gathering screenshots, placing them correctly into a document, and creating captions extremely tiring. I figured it’ll be easy to automate and also a great opportunity to get to know the Browser API, and here we are with the first release of the extension. It’s extremely easy to use but barebones which I plan to change in the near future, so any feedback will be appreciated. I want to keep the docs generation process completely offline to avoid dealing with server costs and GDPR stuff which poses a lot of challenges when planning more advanced features like image editing. It’s available only for Firefox because of Firefox’s great Browser API support, which Chromium currently lacks. Also, there’s a tool like this already available, called Scribe but it requires an account and also is not available for Firefox for some reason. Hope you’ll like it!

Show HN: Create a Children's book with AI – with illustrations https://ift.tt/jz0Eslc

Show HN: Create a Children's book with AI – with illustrations Hey together with wife we took part in AssemblyAI hackathon and although we didn't win we felt good enough about our inital MVP that we took it a bit further. You can describe your characters and give a title and however long/detailed description you want, the gpt-3 will generate a children's story from it, dall-e will generate images. Images are postprocessed with stable-diffusion custom model (for stylisation) and that's the final result. It's still early as it was done in about 2 weeks, but I count on your feedback. I am software engineer and did basically all of the engineering work myself. Feel free to ask question regarding implementation plans, etc. cannot wait to learn what you think. I'll appriciate any feedback. https://ift.tt/eRk2WBP December 23, 2022 at 12:38AM

Show HN: A Python AST viewer for the terminal https://ift.tt/2vP7HGM

Show HN: A Python AST viewer for the terminal Hey HN! I've been having a play with the idea of building a Python AST viewer that can be used in the terminal. It's very early days yet, but the basic approach is now available for playing with. Also on PyPi and works fine on GNU/Linux, macOS and Windows. https://ift.tt/8jwue2o December 22, 2022 at 08:12PM

Show HN: Decentralized Database https://ift.tt/oeISDRb

Show HN: Decentralized Database DB3 is a community-driven layer2 decentralized database network. Infinite Storage Space Scalability is the key to the web3 explosion, db3 will use the following strategies to achieve web3 scale PC can meet the minimum system requirements so everyone can join the db3 network to provide storage space. Using dynamic sharding to achieve scale out. when a storage shard chain has not enough space to store mutation, it will split itself into two subchains. Using cold data archive to recycle storage space. history cold blocks and cold state data will be archived to FileCoin and the storage node will always has storage space to store new data. Blazed Fast and Provable On-chain Query Currently, decentralization means bad performance but db3 is trying to make a big improvement in performance Merkdb is the storage engine of db3 network and it not only has high performance but also the fast-proof generation Geo distribution, the nodes in every storage shard are geo-d

Show HN: Write 500 Words a Day Hello! I made a web application for my friend and I to use as part of a New Year’s resolution and decided to open it up to the public. It’s pretty simple but I’ve really enjoyed building it and using it so far. I’ve written ~10,000 words, which is a lot more than I used to write. Enjoy and be nice! https://ift.tt/CkIrYeW December 22, 2022 at 02:29AM

Show HN: How to use ChatGPT+ARKit to script experiences with natural language https://ift.tt/0Mzv3Yl

Show HN: How to use ChatGPT+ARKit to script experiences with natural language Video demonstration: https://youtu.be/bJFa5HOmhl4 I created a demo involving ChatGPT, OpenAI's Whisper running on-device for speech-to-text (because why not?), and ARKit. By defining a custom JavaScript environment with JavaScriptCore and describing it to ChatGPT, I was able to get it to produce functioning scripts that instantiate and manipulate 3D objects. Sketchfab is used to import 3D assets on the fly. Google Poly had a much better catalog of assets for this sort of thing but sadly, it's no longer available. The README.md describes how it all works but the gist of it is that user prompts are wrapped in a larger prompt that describes the environment (i.e., which functions are available to use and how they work) and constraints. The code is then executed directly. Assets for objects are fetched as needed by searching Sketchfab. https://ift.tt/foX6VFK December 22, 2022 at 12:21AM

Show HN: OpenAEDMap – Automated External Defibrillators from OpenStreetMap https://ift.tt/iXGvWc9

Show HN: OpenAEDMap – Automated External Defibrillators from OpenStreetMap Hi everyone, OpenAEDMap ( https://openaedmap.org/ ) allows you to find (and add!) AEDs in your area. These devices have proven themselves as life-savers in heart failure - when every second matters. The data is synced to OpenStreetMap database, so it's openly licensed (ODbL) and can also be used in other OSM-based apps. AFAIK, there is no other comparable map - they are either proprietary or show a single country. Frontend: https://ift.tt/uL5QAer Tech stack: React, MapLibre GL JS, Bulma Backend: https://ift.tt/kEq8a37 Tech stack: Python, PostGIS https://openaedmap.org December 21, 2022 at 05:31PM

Show HN: A vichan variant that ChatGPT helped me host https://ift.tt/SxvWGEw

Show HN: A vichan variant that ChatGPT helped me host I recently set up a website hosting vichan [0] with nginx, and named it "h2ochan", inspired by the chaotic (yet moderated!) nature of imageboards like 4chan and 2chan. Plus, I love having a liter of water within arm's reach at all times. In the future, I have some plans for threading and posts that will further emphasize the "water" theme and encourage community engagement. In the past, I had tried setting up vichan a few times, but I was overwhelmed by the many technical tasks involved, such as using a remote terminal, working with MySQL databases, configuring nginx, setting file permissions and owners, and using Emacs (or trying to avoid clunky local file edits and FTP). However, I recently discovered chatGPT and have found it very helpful in assisting me with various technical issues. I began by asking for help setting up a public PHP forum, saying that I was a gamedev with some experience in Unity and C#,

Show HN: A new word game with a travel theme This is an independently created word game our family has been working on for a few years. It has uses a license plate motif for word puzzles where the quality of the answers drive a virtual travel experience. The game is web-based, works in all browsers, is fully responsive for mobile screen sizes and also works as a Progressive Web App (PWA). It is written in Django/Python and a modicum of Javascript. https://ift.tt/kIyNbMg December 20, 2022 at 04:50AM

Upcoming Capacity Indicators

Upcoming Capacity Indicators By Christopher Ward Next Generation Customer Information displays will show capacity indicators: One figure means there are many seats available. Two figures indicates that there are likely a few empty seats available. Three figures tell you that there’s likely only standing room available. The SFMTA continues expanding trip planning and accessibility features and improving Muni predictions. This is part of the ongoing Next Generation Customer Information System (CIS) project . One of the newest features is a capacity indicator. A capacity indicator helps customers understand how much space is available on vehicles. Customers can see the indicator on our Next Generation displays in the bus shelters and on train platforms. Customers may use this information to make travel choices. For example, customers can choose to wait for a less full vehicle or take an alternative route. As of November 2022, Muni vehicles equipped with automatic onboard passenger

Show HN: Infisical – open-source secrets manager https://ift.tt/FnrBGuk

Show HN: Infisical – open-source secrets manager Last month, we open-sourced Infisical ( https://ift.tt/OwXv1rF ) - a simple, end-to-end encrypted tool to sync environment variables across your team and infrastructure. You can use it to store environment variables and inject them into your applications locally or into CI/CD and production infrastructure. It can be used with any language/framework and is platform independent with a super easy setup. We know secret managers exist but, in our experience, they’re too complicated, not comprehensive, not user-friendly, or a mix of all three — other nicer ones are closed-source and don’t have self-hosted options available. That’s why we’re on a mission to make secret management more accessible to every developer — not just security teams. We’ve launched this repo under the MIT license so any developer can use the tool. The goal is to not charge individual developers. We make money by charging a license fee for some future enterprise features

Show HN: Real or AI? A game to spot DALL-E 2 generated images https://ift.tt/Ls3uWow

Show HN: Real or AI? A game to spot DALL-E 2 generated images I built this project last weekend. I was playing around with DALL-E 2 and I was impressed by how photorealistic the images generated are. I decided to build a small game to guess if the image is real or AI generated. This is my first ever weekend project, so I would appreciate any feedback :) Thanks https://ift.tt/lFCpNrv December 19, 2022 at 05:57PM

Show HN: Screen Studio – Beautiful screen recordings in minutes https://ift.tt/owHqTu4

Show HN: Screen Studio – Beautiful screen recordings in minutes Hey! I started working on this app 4 months ago. The idea is simple: automate creating promo quality videos that include screen recordings as much as possible Currently it makes cursor movement smooth, zooms in on clicks, adds background and frame around recorded window and adds cinematic motion blur. I plan to add selfie camera support, full text slides and multi-clip recordings. Works only on macOS. It is paid software (one time payment for license + 1 year of updates), but you can download and try it for free - everything except final export to file will work 100% Thanks! https://ift.tt/VXDqW2y December 19, 2022 at 05:00AM

Show HN: Log in to Mastodon with your Twitter account https://ift.tt/kzJmTF1

Show HN: Log in to Mastodon with your Twitter account This is an idea I've had for a while. Given recent events, I decided to finally implement it and see what happens. I assume if it gets any traction it will be banned. The bigger picture here is that Twitter's network of users and follow lists is potentially reverse-engineerable. Why not take that network graph and implement it in the Fediverse? https://tweedle.social December 19, 2022 at 05:38AM
