Show HN: Australian Acoustic Observatory Search The Australian Acoustic Observatory ( https://ift.tt/yRBq6gU ) has 360 microphones across the continent, and over 2 million hours of audio. However, none of it is labeled: We want to make this enormous repository useful to researchers. We have found that researchers are often looking for 'hard' signals - specific call-types, birds with very little available training data, and so on. So we built an acoustic-similarity search tool, allowing researchers to provide an example of what they're looking for, which we then match against embeddings from the A2O dataset. Here's some fun examples!

Show HN: Why an Open Source JSON-LD Database We are pleased to launch a public preview of an open source JSON-LD database which combines the simplicity of a document db with the analytical power of semantic graph. We hope it is approachable for most any developer while having the capabilities, when needed, for data interoperability, embedded cell-level security (ReBAC style), rich shape/schema restrictions, data provenance (time travel), and fact inferencing. Why did our team at Fluree build this? Data is increasingly critical for great decision making, AI, and more. The way we typically store and manage data, mainly as an application state store, makes it challenging to leverage data strategically. The popular approaches to leveraging data outside of an app are difficult to scale and have limited effectiveness (e.g. copy/paste of stale, un-permissioned data into a lake/ warehouse, custom python scripts for feature enrichment, ETL tools). We believe a shift in view for data management ...

Show HN: Bi-directional sync between Postgres and SQLite Hi HN, Today we’re launching PowerSync, a Postgres<>SQLite bi-directional sync engine that enables an offline-first app architecture. It currently supports Flutter, React Native and web (JavaScript) using Wasm SQLite in the browser, with more client SDKs on the way. Conrad and I (Ralf) have been working on our sync engine since 2009, originally as part of a full-stack app platform. That version of the system is still used in production worldwide and we’ve learnt a lot from its use cases and scaling. About a year ago we started on spinning off PowerSync as a standalone product that is designed to be stack-agnostic. If you’d like to see a simple demo, check out the pebbles widget on the landing page here: https://ift.tt/NMxmnbs We wrote about our architecture and design philosophy here: https://ift.tt/sjdUVHD... This covers amongst other things how we designed the system for scalable dynamic partial replication, why we use a ...

Show HN: Costnip – a peer-driven healthcare price transparency platform Costnip is a peer-driven healthcare transparency platform that allows users to compare services based on price, proximity, and what others were charged. We use data to increase competition in healthcare services, empower value-based options and drive down costs via transparency. A founder going through cancer treatment was mistakenly charged $30 instead of the $2000 for a drug because the pharmacy mixed up his name with his father. Then wondered why we all don’t know the cost that other’s are paying, like every other industry outside healthcare. He worked on several other tech innovations through the years before bringing that knowledge to this problem. https://costnip.com November 28, 2023 at 11:22PM

Show HN: SwaraNotebook – a notation editor for Indian classical music As an enthusiast of Indian classical music, I needed to write music notations in the traditional typeset format. When I didn't find any existing editors, I developed a Swara Notebook, a mobile focused web app to write North Indian Classical ( Hindustani ) music notations. The notes (called Sargam , similar to Solfege) can be written in English, Devnagri and Bangla scripts. The transcribed song can be played back in 6 different rhythmic cycles ( Taal ) to the accompaniment of the Tabla (a type of drum) or a metronome. Here's an example of a transcribed song https://ift.tt/2CJhOa4... Since North Indian classical music is oriented around Ragas (similar to modes in western classical music), the keyboard adapts to the notes of a Raga , making it contextually easier to key in notes. A common question I get: can it handle microtones? I chose to not support microtones and other pitch ornamentation such as glissando (...

Show HN: I built a guided Build your own DNS Server challenge Hey everyone. It's Sherub here, author of the Build your own DNS Server challenge on CodeCrafters. Currently it’s available in Rust, Go, and Python and is free while in beta. https://ift.tt/zTEgoSF I've kept the challenge accessible but still challenging for an intermediate developer. This challenge, like others from CodeCrafters, is self-paced. You can use any tools you prefer (terminal, editor, etc.) to build the project.

Show HN: MesoSim – DSL for Options Trading Hello, I quit my engineering job in 2021 to fully focus on trading. After a year of limited success with stocks (algos floating around break-even) I started studying Options. It turned out that selling options (risk premia harvesting) is a sound approach for income generation. Back in the day there were no suitable automated backtesters to effectively study these trades, so I built one: I infused JSON with Lua to create a Job Definition which models how Options Traders build, adjust and hedge their positions. Fast forward to today, many retail traders and small hedge funds are using MesoSim on a daily basis. They executed over 120k backtests with strategies frequently reaching (and exceeding) Sharpe Ratio of 3.

Show HN: New Version of MyOwnDB After nearly 5 years of development, I'm happy but also a bit anxious to Show HN the new version of MyOwnDB [1], a web application for data management at human scale. The app was initially published in 2006 using the then-recent Ruby on Rails, and incorporating fresh Ajax (YUI) and cloud (S3) technologies. Although the app stayed available all these years, it stagnated feature-wise because making changes appeared to become harder and harder due to some technology choices. Learning lessons from that [2], I decided to rewrite it, and chose F#[3] and WebSharper[4]. Those proved to be good choices, but now comes the harder part for me: promoting it and commercialising it. I think the app proposes some interesting features like: - multi-lingual UI - lots of help throughout the app - intuitive data types like file attachments, email address, URL, choice in a list, ... - a form embeddable in a website for data collection These are some points I'm curren...

Show HN: Rethink note-taking and learning experience Hey! Just launched my new project. The cmaps platform was created after a long period of research and development in the field of education. It's known that human thinking is not linear, but rather associative. Without realizing it, we are constantly making connections between the things we learn. I believe that the best way to learn is to make these connections explicit. Instead of studying and taking notes in a linear fashion, we should be able to create a map of the concepts we are learning. This way, we can see the big picture and understand how everything is connected. I can say that cmaps is helping me a lot, mostly on my masters notes. That's why I believe it can help others too.

Show HN: Bemi – data versioning and time travel for PostgreSQL Hi HN, we’re Evgeny, Arjun, and Donna - the builders of Bemi ( https://bemi.io ). Bemi is an enhancement of your existing transactional database to unlock time travel querying. We enable engineers to track all PostgreSQL state changes. We used to all work together at a startup five years ago, and now have got the gang back together to work on Bemi! Many open-source libraries already track data changes, but they’re not reliable since they don’t track changes made outside ORMs with direct SQL queries. Additionally, they come with runtime performance overhead since they’re making database inserts in callbacks. We’ve also consistently seen hacks that engineers write on top of the libraries to store additional context or make it easier for them to query. There are databases already available for event sourcing, but we take a fundamentally different approach. We don’t want engineers to have to rearchitect their existing code, swi...

Show HN: Convert any screenshot into clean HTML code using GPT Vision (OSS tool) Hey everyone, I built a simple React/Python app that takes screenshots of websites and converts them to clean HTML/Tailwind code. It uses GPT-4 Vision to generate the code, and DALL-E 3 to create placeholder images. To run it, all you need is an OpenAI key with GPT vision access. I’m quite pleased with how well it works most of the time. Sometimes, the image generations can be hilariously off. See here for a replica of Taylor Swift’s Instagram page: https://ift.tt/rDxbGjo I initially had a hard time getting it to work on full page screenshots.

The web-based offerings all take forever and seem flaky, and you need to process one video at a time, with no control over the transcription settings. In contrast, my script lets you convert a whole playlist in bulk with full control over everything. It's truly easy to use-- you can clone the repo, install to a venv, and be generating a folder full of high quality transcript text files in under 5 minutes. All you need to do is supply the URL to a YouTube playlist or to an individual video file and this tool does the rest automatically. It uses faster-whisper with a high beam_size, so it's a bit slower than you might expect, but this does result in higher accuracy. The best way to use this is to take an existing playlist, or create a new one on You...

Show HN: DataSheetGrid, an Airtable-like React component I've built and have been maintaining a React component that renders an Airtable / Notion-like component for a few years. This can be seen as an where the value is an array of objects. You can then specify any number of columns that are each responsible for rendering an input for a specific key. The component handles all accessibility features like keyboard navigation, adding / removing rows, context menu, virtualization... If you ever need your users to input long lists of data, this might be a good way to render the form! https://ift.tt/Oa7HEQL November 11, 2023 at 10:36AM

Show HN: Regexdiff – a novel way to analyze regular expressions regexdiff is a tool that finds the difference (think `diff` or Levenshtein distance) between a string and a regex. That means it shows the steps required (insertions and deletions) to turn a given string into one that matches a given pattern. I'm not the first person to have this idea or to come up with the algorithm (for example, a few existing engines use this to implement approximate matches), but it wasn't available in a convenient form, so I decided to make this little toy. In order to support lookaround, it also includes an algorithm that compiles arbitrary-length lookahead and lookbehind into a DFA. I haven't seen this done anywhere before. While this isn't the most substantial project, I have managed to find a few uses for it since I made it half a year ago, so I thought I'd share it here. https://regexdiff.com/ November 7, 2023 at 02:08AM

Show HN: Podsumer – A Self Hosted Podcatcher Podsumer subscribes to your podcast feeds and downloads them to your server for serving/listening from there. It can serve its own feeds to be used in your podcast app(s). Finally, it features a web based player for listening from anywhere. I run this behind gluetun so that feed and media downloads happen over VPN. I am an avid self-hoster. I made this podcatcher to handle my podcast listening needs. My goal isn't to make something that looks super slick, just something that is useable and gets the job done. I could really use some feedback from other self-hosting podcast listeners! https://ift.tt/0wtFhEY November 7, 2023 at 04:23AM

Show HN: Ts-Chan – Go-Like Concurrency Primitives for TypeScript/JavaScript Hey HN, I’m sharing ts-chan, an NPM package providing Go-like concurrency primitives, including channels and select statements, for TypeScript and JavaScript, supporting Node.js, Deno, Bun, and browsers. This is something I've built to make implementing Go-style "control loops" feasible in JavaScript, but there are many possible applications. Highlights: - Features a FIFO processing Chan class and versatile Select class for concurrency control. - Supports buffered channel and channel close semantics very close to Go's. - TypeScript-first implementation. - Defines a simple "channel protocol" inspired by JavaScript's iteration protocols, that's used by `Select`, and implemented by `Chan`. - Makes an effort to mitigate cycles caused by the behavior of JavaScript's microtask queue. - Ongoing project with active iteration for a production-ready module (pre-v1, so the API isn...

Show HN: Gogosseract, a Go Lib for CGo-Free Tesseract OCR via Wazero Tesseract is one of the largest Open Source OCR (Optical Character Recognition) projects. There is already a Go library for using Tesseract from Go with CGo, called Gosseract. However if you are interested in OCR from Go without C complicating building and cross-compiling, there aren't any other options. Wazero is a Go WASM runtime that doesn't have any CGo dependencies. With Emscripten Tesseract has been compiled to WASM and ran within Wazero. Gogosseract provides a simple API on top of this. This project has been an interesting delve into the world of WASM. https://ift.tt/Qg2pUsD November 5, 2023 at 12:06AM

Show HN: I started building yet another CSS framework I really wanted to move my automation server project to a proper framework instead of the current ad hoc nightmare of inline CSS and redundant classes... But nothing seemed quite right. None of them seem suitable for deep restyling without changing markup. So, I took all the good parts of my current CSS, replaced the bad parts with things I liked from the most popular frameworks, then extracted it as a standalone library. The whole thing is 17.5kb, without minifying or removing comments. It starts with classless styles for semantic html. There is a very small set of about 5 components(The intent is to basically build everything with mostly just windows, cards, and toolbars), and a mix of high and low level utilities. There's a 12 column grid(not a real CSS grid, trying to keep it all flexbox all the time, it's just simplegrid pared down even more), a very small collection of sizing primitives. I don't like the whole w-1 ...
