Show HN: A Path-Based Data storage/retrieval web service to prevent crawling I listed my email on GitHub, and it got collected and used without my consent... To prevent this, I created a simple service using Django and PostgreSQL. As you can see when you access the site, you can save data by specifying a path. Think of it as a global key-value storage designed simply to prevent crawling. The data is not stored in an encrypted form, so please do not save sensitive information. Thank you. P.S.: Yes, I am a Faker's fan. https://hideonbush.com/ July 31, 2024 at 04:40AM

Show HN: I made a tool to easily transform and manipulate your JSON data https://ift.tt/tYMTbId

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/A4vYt0k (Link in case the other url doesn’t work) https://ift.tt/A4vYt0k July 30, 2024 at 11:25PM

Show HN: How I wrote a LaTeX paper without writing any LaTeX https://ift.tt/x6kF4X9

Show HN: How I wrote a LaTeX paper without writing any LaTeX Stempad is an online scientific text-editor. I built it because I wanted a way to do fast scientific writing with just my keyboard, and LaTeX wasn't cutting it. I recently launched the ability to export Stempad documents to LaTex. I tested it by rewriting part of a paper I found online (Metabolic scaling in small life forms by Marc E. Ritchie & Christopher P. Kempes) and exporting it. You can try the editor and export yourself using the post url. The export button is on the top right of the page. In case you want to see the result directly, this was it: https://ift.tt/qXIJvNA Feedback is really appreciated! If anyone thinks they might find Stempad useful, let me know and I'd love to get in touch. https://ift.tt/5tSU061 July 29, 2024 at 04:24AM

Show HN: ThinkPost – split-panel note taking & brainstorming app for devs https://ift.tt/tQg4KwY

Show HN: ThinkPost – split-panel note taking & brainstorming app for devs ThinkPost is an Interactive split-panel diagramming, draggable block-based note-taking, and brainstorming tool. I developed ThinkPost as a side project for few months now. Basic idea is parallel streaming of ideas. It's a desktop web app with a very scaled down mobile version just for support. Whole my career I had been working with startups and specifically early stage ones, and it's a big responsibility to devise a feature on our own, think deeply about it in different streams (logically, security, re-usability, platform APIs etc.) and even present distilled part of it to stakeholders (Often times non technical people). Even now I run backend/infra/mobile/qa/customer support/integrations for a healthcare startup, so stakes are high. There's a lot of self brainstorming in multiple streams and then there's also distillation process. I couldn't really work with single page notepads for that streaming process. We should be able to note down in split-panels, so there's space for parallel ideas. Many note-taking apps today single-paged have high-think-threshold (windows notepad/apple notes have very low-think-threshold), you have to think before you write in them, so not a good option for quick ideas. So built a platform specifically for everyone who can parallel stream ideas in split panels Textually (low-think-threshold), write as they like), Diagrammatically, Code-wise or even Quick Maths. And also move the idea blocks across panels or within! or Open a new tab if you want more! I'm personally a massive user of my app because I plan everything at my current job via this app, run meetings, self-brainstorm features, study requirements, visualize code-ideas, an develop this when I get time as well. All completely free. Might run ads later. https://thinkpost.io - Try! no login needed. More comprehensive introduction: https://ift.tt/LEG7qfc... https://thinkpost.io July 28, 2024 at 09:49PM

Show HN: Preprocessor I've been working 4 years now https://ift.tt/kIiVrEH

Show HN: Preprocessor I've been working 4 years now Hey there, I'm here today to share with you a software I've been working on for 4 years now. I'm not full time dedicated to it, as I need to make a living. My inspiration to develop it came when I started using Sass for real in production. I really appreciated the hierarchy of nesting rules instead of the way CSS vanilla used to do. The obvious nesting rules was easy to read and understand just by looking at. That was something I personally admirated very much. I wondered why there was no HTML preprocessors as revolutionary as there is for CSS and JavaScript. All popular preprocessors for HTML have one thing in common. All replace the angle brackets by something else (usually identation) and then add some functionalities on top of it. If the symbols for markups are a problem to the experience of developing a visual structure, just replacing it for something else doesn't fix the problem. You are just changing the character of marcation for another. With that in mind, I started Pretty Markup. Not just replacing the clutter of angle brackets by something else, but removing it completely. Very much inspired by Sass. No special characters needed, except by the quotes. The project still in its early stage, but its already useable. I reached a point where it has a stable base to work. Now, I'm plannig the layer of features that will make it usefull and revolutionary as Sass and TypeScript. Its important to note that I didn't started directly in Pretty Markup. I had a previous package called htmlpp-com-github-mopires. Yes, terrible name, but it was a start. Later a decided to make it more professional and with a friendly name. You can give it a shot by having NodeJS and installing it with: npm install pretty-markup I created a syntax hightlighter for VS Code to attract more devs to it. You can use it by searching "pretty markup" on the extensions tab. Now, it's the first one. The next step will be a package to create a basic starter project. Something like the good old create-react-app. Any feedback, suggestion or even a contribution about anything is very welcome. Thank you very much for your attention, Matheus PS: The package available in runkit is very old(and I don't know how to update it there), I do not recommend you to test there. https://ift.tt/lB2cWtj July 23, 2024 at 10:44PM

Show HN: Patchwork – Open-source framework to automate development gruntwork https://ift.tt/tjy9N8W

Show HN: Patchwork – Open-source framework to automate development gruntwork Hi HN! We’re Asankhaya and Rohan and we are building Patchwork. Patchwork tackles development gruntwork—like reviews, docs, linting, and security fixes—through customizable, code-first 'patchflows' using LLMs and modular code management steps, all in Python. Here's a quick overview video: https://youtu.be/MLyn6B3bFMU From our time building DevSecOps tools, we experienced first-hand the frustrations our users faced as they built complex delivery pipelines. Almost a third of developer time is spent on code management tasks[1], yet backlogs remain. Patchwork lets you combine well-defined prompts with effective workflow orchestration to automate as much as 80% of these gruntwork tasks using LLMs[2]. For instance, the AutoFix patchflow can resolve 82% of issues flagged by semgrep using gpt-4 (or 68% with llama-3.1-8B) without fine-tuning or providing specialized context [3]. Success rates are higher for text-based patchflows like PR Review and Generate Docstring, but lower for more complex tasks like Dependency Upgrades. We are not a coding assistant or a black-box GitHub bot. Our automation workflows run outside your IDE via the CLI or CI scripts without your active involvement. We are also not an ‘AI agent’ framework. In our experience, LLM agents struggle with planning and rarely identify the right execution path. Instead, Patchwork requires explicitly defined workflows that provide greater success and full control. Patchwork is open-source so you can build your own patchflows, integrate your preferred LLM endpoints, and fully self-host, ensuring privacy and compliance for large teams. As devs, we prefer to build our own ‘AI-enabled automation’ given how easy it is to consume LLM APIs. If you do, try patchwork via a simple 'pip install patchwork-cli' or find us on Github[4].

Show HN: A personalised AI tutor with < 1s voice responses https://news.ycombinator.com/item?id=41057030

Show HN: A personalised AI tutor with < 1s voice responses TLDR: We created a personalised Andrej Karpathy tutor that can response to questions about his Youtube videos in sub 1 second responses (voice-to-voice). We do this using a voice enabled RAG agent. See later in the post for demo link, Github Repo and blog write up. A few weeks ago we released the worlds fastest voice bot, achieving 500ms voice-to-voice response times, including a 200ms delay waiting for a user to stop speaking. After reaching the front page of HN, we thought about how we could take this a step further based on feedback we were getting from the community. Many companies were looking for a way to implement function calling and RAG with voice interfaces while retaining a low enough latency. We couldn’t find many resources about how to do this online that: 1. Allowed us to achieve sub-second voice-to-voice latency 2. Was more flexible than existing solutions. Vapi, Retell, [Bland.ai]( http://Bland.ai ) are too opinionated plus since they just orchestrate API’s which incur network latency at every step. See requirement above 3. The unit economics actually work at scale. So we decided to create a implementation of our own. Process: As we mentioned in our previous release, if you want to achieve response times this low you need to make everything as local as possible. So below was our setup - Local STT: Deepgram model - Local Embedding model: Nomic v1.5 - Local VectorDB: Turso - Local LLM: Llama 3B - Local TTS: Deepgram model From our previous example, the only new components where: - Local Embedding model: We chose Nomic Embed text v1.5 model that gave a processing time of roughly ~200ms - Turso offers local embedded replicas combined with edgeDB’s which meant we were able to achieve 0.01 second read times. Pinecone also gave us good times of 0.043 seconds. The above changes led us to achieve sub 1 second voice-to-voice response times Application: With Andrej Karpathy’s announcement around [Eureka Labs]( https://eurekalabs.ai/ ), a new AI+Education company we thought we would create our very own personalised Andrej tutor. Listen to anyone of his Youtube lectures, as soon as your start specking, the video will pause and he will reply. Once your question has been answered you can then tell him to continue with the lecture and the video will automatically start playing. Demo: https://educationbot.cerebrium.ai/ Blog: https://www.cerebrium.ai/blog/creating-a-realtime-rag-voice-... Github Repo: https://github.com/CerebriumAI/examples/tree/master/19-voice... For demo purposes: - We used OpenAI for GPT-4-mini and embeddings (its cheaper to run on a CPU than GPU’s when running demos at scale. These changes add about ~1 second to the response time - We used Eleven labs to clone his voice to make replies sound more realistic. This adds about 300ms to the response time. The improvements that can be made which we would like the community to contribute to are: - Embed the video screens as well that when you ask certain questions it can show you the relevant lecture slide for the same chuck that it got context from to answer. - Insert the timestamps in the vectorDB timestamps so that if a question will be answered later in the lecture he can let you know This unlocks so many use cases in education, employee training, sales etc that it would be great to see what the community builds! https://educationbot.cerebrium.ai/ July 24, 2024 at 07:11PM
