Show HN: Jarvis-AI, an AI Agents network that kills admin work in big corporate https://ift.tt/VW3BuaL

Show HN: Jarvis-AI, an AI Agents network that kills admin work in big corporate Cheers HN, We're Oli and Pascal, two friends from ETH Zürich. We built a network of AI Agents for large organisations, that finally gets rid of all admin work for employees. Current features are: - Schedule, move or cancel meetings (via Google Calendar or locally) - Dynamically adapt meetings according to stakeholders’ availabilities (internal communication of the agents) - Summarize incoming mails (via Gmail) - Create a project plan (command: plan XXX = [project description]) including stakeholders, timeline and cost estimate - Plan, assign and view tasks - Do all of the above via audio We believe that the network point is the core of the product. If you're planning a new project, Jarvis should not only give ideas but also propose whom to work with based on the context information of all the other Jarvises in the company. Instead of sending mails, information flow happens between the Agents and the audio feature makes it super natural to speak to your Jarvis. This is very early stage, so any advice/feedback is much appreciated :) https://ift.tt/8LjBhvw April 30, 2025 at 10:49PM

Show HN: I made an app to learn guitar scales https://ift.tt/litxru2

Show HN: I made an app to learn guitar scales Hi, I'm Sergei, the creator of Guitartonic. I've been playing guitar for 17 years, but never really learned how to improvise. Most of the elaborate music theory PDFs I found online overwhelmed me, so I built a simple tool to practice basic scales and modes. It worked so well that it even inspired my roommate to pick up his guitar again. The app has been live for a few months. I had moved on to other projects and almost forgot Guitartonic existed, until the website started getting organic traffic. I noticed that people were coming to the site (somehow, 90% of the traffic is direct) and staying for four to ten minutes on average. So someone was actually using it! I even received a few heartwarming messages from users saying Guitartonic rekindled their love for playing guitar. Yesterday, someone donated $25 to support my work, which motivated me to share the project here and ask for feedback. Fellow guitarists, how did you learn scales and improvisation? What helped you the most along the way? I'd love it if you gave Guitartonic a try and let me know what you think! https://ift.tt/VqhHMeC April 29, 2025 at 11:25PM

Best of all – self hosting is very cheap and trivial with Railway, so you can add your own customizations to how the RSS bot works. I've been using a personal Discord server as my RSS hub – it's convenient and I can setup different channels for different newsfeeds (i.e. an HN channel for the frontpage).

Show HN: Infrabase – Prompt-Ops for AWS https://ift.tt/GXOZy3u

Show HN: Infrabase – Prompt-Ops for AWS We too at first thought that letting an LLM manage your AWS account must be a bad idea. What could possibly go wrong?? However we couldn’t resist building it, and when we did, we were surprised how much it can do even in plain vanilla form, which currently is just the ai-sdk frontend with some aws sdk code generation (inspared by aws-mcp). We all but stopped using the AWS console internally and switched to Infrabase - a lot of the time it’s much faster to prompt than to click around in AWS console, especially for things that involve multiple steps, IAM roles, etc. So we started to think of making a publicly-launchable product out of it. Some of the things that were missing: - Auth - Some form of checking / validation of the generated aws-sdk code - OIDC or cloudformation template instead of keys to connect AWS accounts - Support more infra tools, not just AWS (datadog, github, sentry, …) - User actions for tool use / explicit approval of risky operations - Export to Terraform / OpenTofu But then we thought, the only thing that is really missing is auth; the rest of the list would still be a blocker for many people, but not for everyone. So we shipped auth and here we are - perhaps someone is crazy enough to try it as-is and sharing your thoughts! https://infrabase.co April 29, 2025 at 12:49AM

Show HN: Gemini Document Processor – Generate Th Summaries from PDF/ePub with AI https://ift.tt/kUJtjRZ

Show HN: Gemini Document Processor – Generate Th Summaries from PDF/ePub with AI Hello HN! I'd like to share Gemini Document Processor, an open-source tool I've developed. This tool uses Google's Gemini AI (their latest API) to create high-quality Thai language summaries from PDF and EPUB files. Key features include: - Support for both PDF and EPUB files - Intelligent chunking for efficient Gemini API processing - Automatic image extraction from documents - Direct integration with Obsidian (export directly to vault) - Smart retry system when errors occur (switches models/increases timeouts) - Real-time progress tracking via web interface I built this tool because I needed to read many English documents and wanted detailed summaries in Thai. If you frequently read long documents or want to build a knowledge base from multiple sources, this tool could save you significant time. The output is a well-formatted Markdown file with images and metadata, ideal for storing in Obsidian, Notion, or other PKM systems. Try it by cloning the repo and running it with Python (requires a Google Gemini API key). Feedback, suggestions, and contributions are very welcome! https://ift.tt/zUbSh0X April 26, 2025 at 04:50PM

Show HN: I used OpenAI's new image API for a personalized coloring book service https://ift.tt/4qNbW8d

Show HN: I used OpenAI's new image API for a personalized coloring book service I've had an idea for a long time to generate a cute coloring book based on family photos, send it to a printing service, and then deliver it to people. Last month, when OpenAI's Sora was released for public use I (foolishly) thought I'd manually drag-and-drop each order’s photos into Sora's UI and copy the resulting images back into my system. This took way too much time (about an hour for each of the few books I made and tested with family and friends). It clearly wasn't possible to release this version because I’d be losing a huge amount of time on every order. So instead, I decided I'd finish off the project as best I could, put it "on ice," and wait for the API release. The API is now released (quicker than I thought it'd be, too!) and I integrated it last night. I'd love your feedback on any and all aspects. The market is mostly family-based, but from my testing of the physical book I've found that both adults and kids enjoy coloring them in (it's surprisingly cathartic and creative). If you would like to order one you can get 10% off by tapping the total price line item five times. https://ift.tt/YOqe6sg April 25, 2025 at 02:05PM

Show HN: Nowrite.fun – If you stop typing, your text disappears Hey HN, I built a small experimental writing tool called nowrite.fun. The concept is brutally simple: You set a timer (e.g. 5 minutes), start writing — and if you stop typing, your text vanishes. No drafts, no recovery, no forgiveness. Inspired by apps like Write or Die, but rebuilt from scratch with a lightweight stack: Deno + TypeScript, XState, anime.js, and canvas-confetti. Hosted on Deno Deploy. It’s a tool for short, focused writing sprints — a tweet, a blog paragraph, a newsletter blurb. Keep typing → you win. Hesitate → it’s gone. It’s minimal, a bit stressful, and surprisingly motivating. I also posted it on Product Hunt to see if this kind of weird, borderline masochistic UX resonates with anyone: https://ift.tt/6ZgkKp7 If you find it fun or useful, I’d really appreciate an upvote!

Show HN:[Opensource] AIgr.id–Polycentric Infrastructure for Open and Plural AI https://ift.tt/SNVaURo

Show HN:[Opensource] AIgr.id–Polycentric Infrastructure for Open and Plural AI Hey HN! I'm Kanishka Nithin, founder of AIGr.id ( https://www.aigr.id ). We’re building AIGr.id — a polycentric network of independent, modular AI that can coordinate, exchange data, and compose into higher-level intelligence — all within a decentralized and plural ecosystem. Rings collective intelligence? In simpler terms: We’re trying to make it possible for people to produce, remix, operate, distribute and consume AI systems the way we use the internet— openly, collaboratively, and without needing to centralize everything into one mega-model owned by one mega-entity. Just like internet of intelligence. Today’s AI landscape is: Centralized, resource-heavy systems demand vast funding, compute, and talent—excluding much of the world. Controlled by a few powerful actors prioritizing profit over public good. Participation is limited, deepening inequality in AI benefits. Fragmented and siloed, with no open protocols for AI coordination We believe it's time to reimagine AI as collective intelligence, as shared commons — poly-centric, collaborative, composable, inclusive, and guided by values beyond profit. What’s different about our approach is that we’re not trying to build “the one true model” — we’re trying to make it easier for people to build, remix, run, and govern their own AI systems, together. We want a world where AGI doesn’t have to be monolithic — where different models, agents, and collectives can evolve side by side, coordinate, and even argue if they need to. Plural, by design. At the core of AIGr.id is OpenOS.AI, a distributed AI operating system. It is a full stack AIOS that spans everything from low-level compute orchestration to higher-level cognition, coordination, governance and economic policy. Think of it as a programmable substrate for building and running decentralized AI systems — across any infrastructure, in any topology. Developers can use shared protocols, primitives, and templates to compose AI systems — models, agents, cognitive workflows — and plug them into running grids. These grids can be public, private, federated, or even permissionless. Each grid can maintain its own sovereignty (values, rules, trust mechanisms), but still remain interoperable with others. It's designed for a world where we expect many intelligences to coexist, rather than one model to rule them all. We’re in beta and will be kicking off more extensive scale testing during our upcoming testnet phase. If this scratches an itch for you, or just want to jam on open systems — we’d love your feedback. If you're interested in joining the testnet, you can join our discord @ https://ift.tt/PXeUlKS — we’d be excited to have you involved early. Docs, GitHub, and the paper are all linked at https://www.aigr.id Curious what you think — critiques, weird use cases, edge cases, counterpoints — all welcome. Our own background is what pushed us into this problem. Before this, we were a 4-person crew running one of the largest real-time AI inference workloads in India. We were doing around 500K inferences/sec across 80–90 models simultaneously, supporting 35+ public-sector use cases — mostly video analytics. We were operating across federated and private infrastructure in real time, processing millions of frames per second. We didn’t rely on cloud providers or commercial frameworks. Our market was distorted by deprioritized infrastructure investment and choosing to grow within our earnings means the only way to survive was by being ruthlessly efficient: creating frameworks that automated end to end production, operation, distribution and maintenance life cycle of AI -- everything at scale reliably without or with minimal human intervention — so four of us could actually live our lives, too. So in a way, AIGr.id was born out of necessity. It's the system we wish we had — one that treats intelligence as something modular, networked, composable, orchestratable, shareable, and governable – in a collective way. https://www.aigr.id April 22, 2025 at 09:43PM

Show HN: I made TypeScript's type inference more strict (and smarter) https://ift.tt/nkSy5vH

Show HN: I made TypeScript's type inference more strict (and smarter) As a TypeScript developer, I often found myself wishing the type system could do more—*especially when omitting or modifying deeply nested properties* inside complex objects and arrays. For instance, what if I want to remove a deeply nested field like `user.profile.email` and also something like `user.posts[ ].meta.shares` from a type? TypeScript doesn't really provide a built-in way to do that. So I built *DeepStrictTypes* — a utility that lets you *omit deeply nested keys*, even inside arrays, with full type inference and strictness. Here’s an example: ```ts type Example = { user: { id: string; profile: { name: string; age: number; email: string; }; posts: { title: string; content: string; meta: { likes: number; shares: number; }; }[]; }; }; // Remove 'user.profile.email' and 'user.posts[ ].meta.shares' type Omitted = DeepStrictOmit< Example, 'user.profile.email' | 'user.posts[*].meta.shares' >; ``` The resulting type: ```ts { user: { id: string; profile: { name: string; age: number; }; posts: { title: string; content: string; meta: { likes: number; }; }[]; }; } ``` Works great for: - Cleaning up types for API responses - Dynamically transforming deeply nested data - Improving type safety when handling structured JSON [ https://ift.tt/sVbdRLX ]( https://ift.tt/sVbdRLX ) Would love your feedback or ideas for improvements! https://ift.tt/UsAJzxn April 22, 2025 at 07:47AM

Show HN: Open Codex – OpenAI Codex CLI with open-source LLMs Hey HN, I’ve built Open Codex, a fully local, open-source alternative to OpenAI’s Codex CLI. My initial plan was to fork their project and extend it. I even started doing that. But it turned out their code has several leaky abstractions, which made it hard to override core behavior cleanly. Shortly after, OpenAI introduced breaking changes. Maintaining my customizations on top became increasingly difficult. So I rewrote the whole thing from scratch using Python. My version is designed to support local LLMs. Right now, it only works with phi-4-mini (GGUF) via lmstudio-community/Phi-4-mini-instruct-GGUF, but I plan to support more models. Everything is structured to be extendable. At the moment I only support single-shot mode, but I intend to add interactive (chat mode), function calling, and more. You can install it using Homebrew: brew tap codingmoh/open-codex brew install open-codex It's also published on PyPI: pip install open-codex Source: https://ift.tt/PFr0qLs https://ift.tt/PFr0qLs April 21, 2025 at 09:57PM

Show HN: HN Watercooler – listen to HN threads as an audio conversation https://ift.tt/G57mqvf

Show HN: HN Watercooler – listen to HN threads as an audio conversation Hi HN, here's something fun to play with. It takes any HN thread and turns it into an audio conversation so you can listen to the thread while doing other things. I've seen many previous attempts to turn HN threads into podcasts, but they all shared a common issue IMO: trying to reduce the very rich back-and-forth into a single-thread single-reader boring podcast. Instead, I wanted to hear the actual debate from the actual thread! So I asked Claude 3.7 to build this for me as a browser-only app. It just needs a thread URL and an Elevenlabs API key (this all remains in your browser, you can check the source code, it's only 3 files, there is no server storage of anything). To make the resulting audio experience as natural as possible, each commenter has a different voice. Commenters who appear multiple times in the thread have the same voice, and introduce themselves. A bit of context is also introduced when coming back "up" from deeply nested comments. You can play the resulting audio or download it for later listening. I'm planning to later add the ability to load multiple threads so I can have a playlist generated for listening in the gym! Any comments or improvement suggestions are appreciated! https://ift.tt/FLMy0Qr April 17, 2025 at 10:54PM

Show HN: We made a VS Code extension to recreate a debugger experience from logs https://ift.tt/v84zCyQ

Show HN: We made a VS Code extension to recreate a debugger experience from logs A month ago [1], we made an MCP server so Cursor can debug Node.js on its own. We emailed every person that starred our repository [2] and learnt that frontend devs really want to give Cursor access to browser logs, and that backend devs (our intended audience) do not use debuggers nearly as much as we thought. We interviewed friends across startups and discovered that they use logs to debug, because they can’t run services locally on their machine. The services (1) require too much disk, RAM, or CPUs to run locally, (2) have too many service dependencies (think microservices), or (3) are a faff to instantiate locally with a debugger. Instead, our friends instrument their services, deploy them to staging environments via Kubernetes, and then query the logs via data stores (think Grafana, Axiom.co, Google Cloud Logging, etc) or directly (think Kubernetes logs). We thought: "What if we could recreate a debugger-like experience from logs?". That would save them from browsing logs and trying to make sense of them outside the context of the code base. We looked into it and made a VS code extension that lets you (1) import logs, (2) go to the line of code associated with a log, and navigate up/down the probable call stack associated with a log. It's a prototype, but if you're interested in trying it out, we'd love some feedback!

Show HN: Particle - News, Organized https://ift.tt/CI31u6y

Show HN: Particle - News, Organized Hello HN! Particle News product engineer here. Keeping up with the news is overwhelming in an age of information overload. Particle reimagines the experience by organizing articles into comprehensive "Stories," offering clear, concise summaries to quickly grasp what matters. Today, we reached the #1 spot in "Newspapers & Magazine" on the iOS App Store—and I thought I'd share a bit of our backstory. I've been connected to this team for a long time. About 20 years ago, I shared a house with our CTO and co-founder Marcel Molina. I helped him get started with programming. Since then, Marcel has had an extraordinary career—becoming a senior staff engineer at Twitter, where he helped build foundational features like Retweets, Notifications, and Lists, and later working at Tesla on manufacturing execution systems that scaled across Gigafactories. At Twitter, Marcel worked closely with our CEO and product visionary Sara Beykpour, who led initiatives like Twitter Blue, Twitter Video, and the experimental app twttr . Sara has a background in Software Engineering and Cognitive Science from the University of Waterloo and spent over a decade at Twitter in engineering and leadership roles. In late 2022, Sara and Marcel started prototyping a news app that could reduce the cognitive and emotional burden of staying informed—by using AI to help people understand more, faster. They were soon joined by a few other former Twitter colleagues who helped shape the early concept into a working iOS application. I joined about 15 months ago to contribute across the entire stack. Since then, I've helped design and build major iOS features, rewritten our public website on Cloudflare Workers, and implemented new functionality in our Go backend, which is driven by Google Cloud's Pub/Sub architecture. What Makes Particle News Different Particle helps you navigate the news effortlessly—leveraging AI to help you understand more, faster. Some highlights: • Personalized News – Your feed is tailored to your interests. You can follow specific people, places, and things so you never miss what matters to you. • Clear Summaries – Get a quick overview or dive deeper with detailed, structured context—summarized in natural language. • Perspective Tools – Features like "Opposite Sides" and our political spectrum chart let you explore stories through multiple lenses. • Interactive Q&A – Ask questions about any story and get concise answers with sources and citations. • Audio Summaries – Use the "Play" feature to listen to your feed, specific stories, or even select articles—great for hands-free or on-the-go moments. One of the things we're most proud of is how Particle supports publishers. We've partnered with outlets like Reuters, AFP, and Fortune to host some of their content via APIs. These partners get prominent placement, and their links are highlighted in gold to stand out. This model aims to drive traffic back to publishers and reward high-quality journalism, rather than just aggregating and commodifying it. Transparency is a core value: all sources are cited, generated answers are grounded in evidence, and we take real care to prevent AI hallucinations or misleading summaries. Despite negligible marketing spend, Particle has grown to the top of its category by focusing on engagement with early users and meaningful partnerships with the media ecosystem. Coming soon: weekday mini crosswords—a new feature designed by another longtime friend of ours from 20 years back who went on to work at Twitter, lead development on Firewatch, and release his own games independently. It's incredibly fun and rewarding to be building something meaningful with old and new friends. I feel lucky every day to work alongside some of the best product, design, and engineering minds on a project we hope will help people stay engaged with democracy without burning out. https://ift.tt/kADi1Lu April 16, 2025 at 01:26AM

Show HN: Torque – A lightweight meta-assembler for any processor https://ift.tt/K054jGS

Show HN: Torque – A lightweight meta-assembler for any processor Hello everyone, I've been working on this project for the past few months. Torque is a meta-assembler: instead of having an instruction set built into the assembler, you use macros to build up a small language that decribes an instruction set and then you use that to write your program. It's designed to work for any microcontroller/processor architecture, you build from the bit level upwards so there aren't any assumptions around word widths, instruction formats, or endianness. I created Torque initially to write programs for a PIC microcontroller, after running into difficulties with the official assembler. I've also used it to write programs for the Z80 processor inside an old TRS-80 computer. Let me know if you try it out or have any questions! https://ift.tt/ob5XT4K April 16, 2025 at 01:46AM

Show HN: LiftmyCV – AI Job Search Agent and Auto-Apply Tool https://ift.tt/NfPOK3A

Show HN: LiftmyCV – AI Job Search Agent and Auto-Apply Tool Hey HN! Dan Zaitsev here – solopreneur and maker of LiftmyCV, an AI job search agent that finds relevant job openings and auto-applies on your behalf. In early 2024, my small marketing team started losing clients due to the rise of AI tools. So I began searching for a job myself and was reminded how frustrating and inefficient the process is – surfing dozens of job platforms, filling out endless forms, and receiving very few responses. I started using ChatGPT to speed up the process and realized it could be automated. That’s how LiftmyCV was born. I built a simple prototype, launched it to a small group of early users, and quickly got confirmation that the idea resonated – people found it helpful and were actually willing to pay. During early testing, I personally received several interview invites in just one week using the product. Yeah, I know some makers already tried (or are still trying) to build something similar – and yes, there are tons of competitors. But I genuinely think I can do it better. Here's how: - Quality over quantity: I saw one guy post about applying to 1,000 jobs in a week… but what actually matters is the quality of each application. So I’m focusing on polishing GPT autofill responses and server logic to make each one more contextual and human. A big upgrade to the AI agent is dropping this week – hope you’ll like it :) - No subscription trap: While others offer pricey lifetime unlocks ($100+) or charge $2.50+ per auto-apply, LiftmyCV runs on a freemium/pay-as-you-go model. Try before you buy – no lock-ins. Since beta launch in Feb 2025: - 942 signups - 70 paying users - $1,225 in revenue - #3 Product of the Day on Product Hunt *all organic with $0 ad spend: YouTube videos, SEO content, and direct outreach Tech stack: - Webapp: Java + Spring Boot + TypeScript + React JS + Effector + OpenAI API - Chrome Extension/AI Agent: JavaScript - Marketing website/landing pages: Wordpress/PHP Core features available in the MVP: - Supports 7 job search websites & ATS platforms - Job search on autopilot - Non-Stop AI Auto-Apply (automatically switches between job boards) - GPT-4o-powered auto-fill for job applications - Auto-apply history and stats - Premium support & open to feature requests - Try before you buy - a free plan with 3 CV submissions How it works? 1. Visit www.liftmycv.com and create your free account 2. Install official Google Chrome extension from the Chrome web store 3. Complete your profile and upload your CV (ensure your profile is as detailed as possible for better results) 4. Activate the AI Auto-Apply feature and let LiftmyCV handle job applications for you Challenges I faced: - Fine-tuning the AI auto-fill logic has been tricky (and it’s still a work in progress). - GPT-generated responses required constant tweaks to avoid awkward or irrelevant form fills. - Humanizing the AI output is essential to bypass ATS systems and make applications feel real. https://ift.tt/ingGwzo April 14, 2025 at 07:45PM

Show HN: Aqua Voice 2 – Fast Voice Input for Mac and Windows Hey HN - It’s Finn and Jack from Aqua Voice ( https://withaqua.com ). Aqua is fast AI dictation for your desktop and our attempt to make voice a first-class input method. Video: https://ift.tt/BJaOXVI Try it here: https://ift.tt/b52LIVa Finn is uber dyslexic and has been using dictation software since sixth grade. For over a decade, he’s been chasing a dream that never quite worked — using your voice instead of a keyboard. Our last post ( https://ift.tt/cg7y4qf ) about this seemed to resonate with the community - though it turned out that version of Aqua was a better demo than product. But it gave us (and others) a lot of good ideas about what should come next. Since then, we’ve remade Aqua from scratch for speed and usability. It now lives on your desktop, and it lets you talk into any text field -- Cursor, Gmail, Slack, even your terminal. It starts up in under 50ms, inserts text in about a second (sometimes as fast as 450ms), and has state-of-the-art accuracy. It does a lot more, but that’s the core. We’d love your feedback — and if you’ve got ideas for what voice should do next, let’s hear them! https://withaqua.com April 9, 2025 at 08:31PM

Show HN: DrawDB – open-source online database diagram editor (a retro) One year ago I open-sourced my very first 'real' project and shared it here. I was a college student in my senior year and desperately looking for a job. At the time of sharing it i couldn't even afford a domain and naively let someone buy the one i had my eyes on lol. It's been a hell of a year with this blowing up, me moving to another country, and switching 2 jobs. In a year we somehow managed to hit 26k stars, grow a 1000+ person discord community, and support 37 languages. I couldn't be more grateful for the community that helped this grow, but now i don't know what direction to take this project in. All of this was an accident. But now I feel like I'm missing out on not using this success. I have been thinking of monetization options, but not sure if I wanna go down that route. I like the idea of it being free and available for everyone but also can't help but think of everything that could be done if committed full-time or even had a small team. I keep telling myself(and others) i'll do something if i meet a co-founder, but doubt and fear of blowing this up keeps back. How would you proceed? https://www.drawdb.app/ April 9, 2025 at 04:20AM

Show HN: Disco – The self-hosting platform I wish existed years ago https://ift.tt/Oy40Tct

Show HN: Disco – The self-hosting platform I wish existed years ago Hey HN, for the past 1.5 years my cofounder Antoine and I have been building Disco, an Open Source deployment platform that lets you host multiple web apps on a single server: https://disco.cloud/ After getting tired of high per-project pricing on platforms like Heroku and Render, and frustrated with Kubernetes' complexity, we created a platform with all the polish and convenience of commercial solutions, but as an Open Source project you can run anywhere. Disco gives you a streamlined experience (ie a clean CLI and web UI) with the freedom and economics of self-hosting. Key features: - Deploy from GitHub with fast deployment times - from git push to being live, our main static site deploys in 2 seconds (really); a medium sized Django app deploys in ~25 seconds - Host multiple projects on a single server, cutting costs by 50%+ compared to per-project pricing - Works with Node, Rust, Python, Django, Rails, static sites, and more - Includes "good enough" Postgres for projects that don't need enterprise features - API keys for team access instead of SSH key management - Run on your own infrastructure - from cloud VMs to Raspberry Pis to on-prem - Built-in horizontal scaling - add servers to distribute the load and increase capacity - Optionally, let us manage the infra for you: same Open Source stack, but less to worry about A real-world example: We moved idealist.org 's staging environments, a highly trafficked site, from Heroku to Disco on a single $50/month server, which now hosts 6 staging environments. On Heroku, each would have cost $500/month ($3k total). We also moved all of Idealist's production frontend SSR rendering to Disco, getting better stability at 1/5th of the cost. I personally moved a number of my hobby sites to a Raspberry Pi that sits at home, saving me hundreds for apps that used to be at Heroku and Render. See my (unhinged) Localhost talk at the Recurse Center about this - https://www.youtube.com/watch?v=z2lP7C8VT6M Speaking of Recurse, we host a "community" Disco installation there i.e. a shared 8Gb Raspberry Pi that's hosting 52 (static/backend/go/python/rust, etc.) web projects at the time of this writing. That's also a fun use case! TLDR: Disco is perfect for both DIY self-hosters and teams looking for a more cost-effective deployment platform. Available now for self-hosting (free and Open Source) or as a managed service. Try it out https://disco.cloud/ and let us know what you think here or on our Discord. Cheers! April 7, 2025 at 11:06PM

Show HN: I made an AI Platform that gamifies applying to jobs https://ift.tt/HbrDe0M

Show HN: I made an AI Platform that gamifies applying to jobs Hi there! I've created ApplyNinja, a platform that uses AI to help jobseekers apply to jobs faster and better. What differentiates ApplyNinja from the other "auto-apply" platforms is the trained AI model behind it. It learns from your resume and the jobs you apply to, and it provides better and better results. Currently, it serves as a helper for the entire application process: - Track & Monitor job applications - Generates Resume suggestions and highlights the parts that are not so good - Auto-fixes and generates a new resume based on the suggestions - Creates Cover Letters based on your resume and the job description - Generates Company Insights, scraping user reviews from Glassdoor, Indeed etc. - Generates Salary Insights so jobseekers have a negotiation leverage - Generates Technical Interview Questions based on the Job Description On top of all of this, it provides a gamified experience, because consistency is the key in applying to jobs. Me and my friends are using it daily and manage to land approximately 5-10 interviews/month as Software Engineers. I would really love any kind of feedback.

Show HN: DuckDB Powered SQL Editor Hi guys, I made an SQL editor that utilizes the duckDB engine to process your queries. As a result, the speed gains are +25% when compared to using any standard editor that connects through JDBC. I built this because I work on a small data team and we can't justify an OLAP database. Postgres is amazing but, if I try to run any extremely complex queries I get stuck waiting for several minutes to see the result. This makes it hard to iterate and get through any sort of analysis. That's when I got the idea to use duckDB's processing engine rather than the small compute available on my Postgres instance. I didn't enjoy writing SQL in a Python notebook and wanted something like dBeaver that just worked, so I created soarSQL. Try it out and let me know if it has a place in your toolkit! https://soarsql.com April 5, 2025 at 12:10AM

Show HN: I made an online free tool site https://ift.tt/pCb63ew

Show HN: I made an online free tool site Hi HN! I've created [UFreeTools]( https://ift.tt/OKnbuT7 ), a collection of developer utilities (60+ tools and growing) that's completely free, ad-free, and runs entirely in the browser. No data leaves your device - everything is processed locally. ## Background As a developer, I found myself constantly searching for simple utilities like JSON formatters, UUID generators, and color pickers. Most existing options were cluttered with ads, required sign-ups, or sent data to servers. I wanted clean, fast tools that respected privacy. So I built UFreeTools as a modern SPA using Vue 3 and Vite with: - 100% client-side processing for all tools - Progressive loading with dynamic imports (only load what you use) - Dark/light theme support - Offline capability for most tools - Responsive design that works well on mobile ## Technical Details Some of the more technically interesting implementations: - *JWT Debugger*: Uses WebCrypto API for verification of all common algorithms - *Symmetric Encryption*: Implements AES-GCM/CBC/CTR with PBKDF2 key derivation - *Image Processing*: Uses Web Workers for non-blocking operations on large images ## Lessons Learned The biggest challenges were: 1. *Performance optimization*: Some tools (like image processors) needed careful optimization to handle large files without freezing the UI 2. *Browser API limitations*: Working around browser restrictions for certain crypto operations 3. *Bundle size management*: Keeping the initial load small while supporting 60+ tools ## Future Plans I'm planning to add: - Tool configurations sync via local storage - More specialized tools for developers based on feedback I built it because I needed these tools myself, and I hope others find it useful. I'd love your feedback, especially on UX, tool suggestions, or if you find any bugs! [Try UFreeTools]( https://ift.tt/OKnbuT7 ) https://ift.tt/OKnbuT7 April 4, 2025 at 09:56PM
