Show HN: I made a tool to easily transform and manipulate your JSON data Hey NN, I've create a tool that allows you to easily manipulate and transform json data. After looking round for something to allow me to perform json to json transformations I couldn't find any easy to use tools or libraries that offered this sort of functionality without requiring learning obscure syntax adding unnecessary complexity to my work or the alternative being manual changes often resulting in lots of errors or bugs. This is why I built JSON Transformer in the hope it will make these sort of tasks as simple as they should be. Would love to get your thoughts and feedback you have and what sort of additional functionality you would like to see incorporated Thanks! :) https://ift.tt/OrSZaRf (Link in case the other url doesn’t work) https://ift.tt/OrSZaRf July 30, 2024 at 11:25PM

Show HN: Semantic Grep – A Word2Vec-powered search tool Much improved new version. Search for words similar to the query. For example, "death" will find "death", "dying", "dead", "killing"... Incredibly useful for exploring large text datasets where exact matches are too restrictive. https://ift.tt/rjZ9GEN July 27, 2024 at 11:32PM

Show HN: Voice Out – Text-to-speech to read any webpage, Google Doc, or PDF Hey everyone I'm the creator of Voice Out, and I'm super excited to share it with you! Voice Out is a Chrome extension that lets you 'read' by listening. It turns any webpage, Google Doc, or PDF into speech with just a click. Now, you can go through your reading list while working, commuting, or doing chores. I packed it with tons of languages and voices so you can customize your listening experience. And the best part? It's completely free! You can also enable commercial voices from OpenAI, Google, Azure, Amazon etc, using an API key. I set mine to use the OpenAI voice - it works great and costs almost nothing. Voice Out will soon add support for three more TTS providers, support reading content inside iframes, and be able to create rules to transform site text (you can use this to rewrite links, bullet points, etc). I'd love for you to try Voice Out and hear your thoughts! Direct link ...

Show HN: Simple headless, serverless, static, git-based CMS I couldn't find a CMS that met all my needs, so I built this prototype. It works for my purposes.

Show HN: Unsearch, an open source alternative to Google Chrome Sync I use several browsers between college, work and home and I like to have them synced so I can find websites I've searched for in a browser when I don't have access to it or access my bookmarks. I don't like the idea of using any of the sync services offered by the major browsers because of how they might use my data, because they lack some features I'd like to have, and because they all try to lock you into their ecosystem. So I'm building an open source cross-browser manager for browsing activity. I would love to hear your thoughts on this concept, and if you have any questions or suggestions, please let me know. https://ift.tt/IBODSoT July 24, 2024 at 10:48PM

Show HN: Zerox – document OCR with GPT-mini This started out as a weekend hack with gpt-4-mini, using the very basic strategy of "just ask the ai to ocr the document". But this turned out to be better performing than our current implementation of Unstructured/Textract. At pretty much the same cost. I've tested almost every variant of document OCR over the past year, especially trying things like table / chart extraction. I've found the rules based extraction has always been lacking. Documents are meant to be a visual representation after all. With weird layouts, tables, charts, etc. Using a vision model just make sense! In general, I'd categorize this solution as slow, expensive, and non deterministic. But 6 months ago it was impossible. And 6 months from now it'll be fast, cheap, and probably more reliable! https://ift.tt/OhwiL25 July 23, 2024 at 10:19PM

Show HN: VS Code Extension to skip the noisy web tools (JSON Prettify, and more) Hi HN, Simple online tools on the web have become unnecessary greedy. For example, * https://ift.tt/qO6LNJu displays 7 ads on page load * https://ift.tt/NSixYVz had 4 ads plus a Google Vignette. And many more sites do the same thing. It's just noisy, which is why I created this VS Code Extension where you don't need to even leave your editor for your small web operations. I also built a Desktop app and an online version, which can be reached or downloaded at smallonlinetools.net. Both of which will be ad-free forever. So far smallonlinetools.net has over 150 tools and I add more everyday! Give it a try and leave me a review is all I ask! Perhaps, share with your friends so we can rank better on Google! https://ift.tt/KftdTbi July 23, 2024 at 08:50PM

Show HN: Briefer – multiplayer notebooks with schedules, SQL, and built-in LLMs Hi HN! We're Lucas and Lucas from Briefer and we're building better notebooks. Our notebooks are kind of a mix between Notion and Jupyter with extra features, like the ability to schedule notebooks, turn them into dashboards and apps, and write SQL queries whose results turn into data frames automatically. We're building better notebooks because we think they're a great idea poorly executed - for three reasons. The first problem with notebooks is that they're difficult to share. Non-technical people don't want to download docker containers and install Python libraries to see what the data team is doing. Then, the data team takes screenshots of their work and pastes them somewhere else. The issue with this approach is that the data gets stale, and the output is not interactive, so it's difficult to get feedback and iterate. The second problem with notebooks is that they get too me...

Show HN: OpenDataCapture an electronic data capture platform for data collection Hi HN, We're the Douglas Neuroinformatics Platform[1], and we've been working on Open Data Capture, a web-based electronic data capture (EDC) platform for continuous clinical and research data collection. You can use it to administer instruments (like forms and interactive tasks) either in-person or remotely. The platform is based on a fundamentally longitudinal data model. Unlike other EDC platforms, which are centered around the concept of a study with rigid timepoints, Open Data Capture is designed for continuous data capture. Data is associated with a given session, which includes metadata such as date, time, and mode (i.e., in-person or remote). We've designed the system around the core restriction that many hospital institutions demand that data remain on-premise, while clinician-researchers often want to evaluate clients outside the institution with research questions. This has resulted ...

I created this game using Unity because I am already familiar with it. If you encounter the tiles is not randomized, please try recreate the tile again, I don't exactly know why it's happenning.

Show HN: I coded my own JSON translation tool to easily localize my side project Hi HN, I’m Joan, the developer of Quicklang. I made this app to easily translate and keep in sync all my localization JSON files for my side projects. While searching online for a similar tool, I only found enterprise solutions that do not allow direct editing of JSON files. I used to use ChatGPT to translate the JSON translation file changes before coding Quicklang. However, I realized that ChatGPT only allows you to input short content for translation into another language (even if you provide a .json file), and each time I had to request translations for one language at a time. So, I decided to build an app that only sends the changes I’ve made to the OpenAI API and easily translates them into all the target languages for my side projects. Technical details: I used Next.js to build the front end and backend, and I use a custom VPS (EC2 instance) on AWS to handle the translation process. This is because ...

Show HN: A modern Jupyter client for macOS I love Jupyter – it's how I learned to code back when I was working as a scientist. But I was always frustrated that there wasn't a simple and elegant app that I could use with my Mac. I made do by wrapping JupyterLab in a chrome app, and then more recently switching to VS Code to make use of Copilot. I've always craved a more focused and lighter-weight experience when working in a notebook. That's why I created Satyrn. It starts up really fast (faster time-to-execution than VS Code or JupyterLab), you can launch notebooks right from the Finder, and the design is super minimalist. It's got an OpenAI integration (use your own API key) for multi-cell generation with your notebook as context (I'll add other LLMs soon). And many more useful features like a virtual environment management UI, Black code formatting, and easy image/table copy buttons. Full disclosure: it's built with Electron. I originally wrote it in Swift...

Show HN: Improve LLM Performance by Maximizing Iteration Speed LLM Application development is extremely iterative, more so than any other types of development. This is because in addition to all the activities involved in regular application development, we also need to make the LLM Application accurate and reduce hallucination. To improve performance, we need to trial and error various combinations of LLM models, prompt templates (e.g., few-shot, chain-of-thought), prompt context with different RAG architecture, try different agent architecture, and more. There are thousands of permutations to try. We need to be able to easily experiment with these different permutations, measure performance in an objective way, and compare performance across each other to find the best possible combination. --- I have been working in AI since 2021 - first at FAANG with ML, then with LLM in start-ups since early 2023. I have had the chance to talk with many companies working with AI. The biggest mista...
