Show HN: DrawDB – open-source online database diagram editor (a retro) https://ift.tt/bR8OtP4

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 05:50AM

Show HN: I created a ELI5 Blockchain glossary, with also a bit of interactivity The reason is simply that I'm learning blockchain and i found myself searching and hardly recalling terminology. So I started building a glossary (that slowly i'm making interactive) in which the terms are explained with ELI5 analogies. AI helped me with that. Hope you find it useful.

Show HN: Latitude.sh Databases – Simple PostgreSQL DBaaS on Bare Metal https://ift.tt/XHelCbk

Show HN: Latitude.sh Databases – Simple PostgreSQL DBaaS on Bare Metal Hi HN, Gabriel here, one of the developers at Latitude.sh (we're a bare metal cloud provider). Over the past year or so, I've been the primary developer building Latitude.sh Databases – our take on a managed PostgreSQL service. The core idea was to offer a straightforward and competitively priced option for developers who need reliable PostgreSQL without overly complex configurations, leveraging the performance benefits of running directly on bare metal. It runs on our global bare metal infrastructure. Key features we've implemented include: * Built-in monitoring & connection pooling * IP Address Whitelisting (Trusted Sources) * Automated backups configured directly to your own S3 bucket (giving you control over storage and potentially costs) * An optional integration with Supabase, allowing you to use parts of their dashboard for enhanced usability with your database. Under the hood, it's built on Kubernetes running on our bare metal servers, using the CloudNativePG operator to manage the PostgreSQL instances. We've found this operator approach works well for handling stateful database workloads in K8s, challenging the old notion that databases don't belong there. The service stemmed from internal needs and early interest gathered from a waitlist (~300 signups). It's currently live and available for use. We're launching it here on HN because we'd genuinely appreciate your feedback on: * The overall developer experience and UI simplicity. * The current feature set (especially the S3 backup and Supabase integration). * Performance perceptions (given the bare metal base). * Our pricing model's competitiveness and clarity. * Any technical aspects of the implementation (running PG on K8s/bare metal). Happy to answer any questions you have! You can check out the product page here: https://ift.tt/UTs1LMq Thanks for looking! https://ift.tt/UTs1LMq April 6, 2025 at 11:30PM

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

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. Thank you very much! https://ift.tt/9X7cF20 April 6, 2025 at 12:09AM

Show HN: Experience iPhone's "Blob Keyboard" prototype from 2005 https://ift.tt/kUnvPlC

Show HN: Experience iPhone's "Blob Keyboard" prototype from 2005 Hi HN, I teach tech design history, and one of the key stories I cover is the development of the original iPhone keyboard by Ken Kocienda. Reading about it in his book "Creative Selection" is great, but I wanted my students (and now you!) to actually feel this step in the process. So, I built a web simulator of the "Blob Keyboard", Kocienda's very first attempt at a touchscreen keyboard that actually works, from September 2005: Try the Blob Keyboard: https://ift.tt/5Cxh7bw... - Tap for the middle letter - Swipe left or right for the side letters More on the github repo: https://ift.tt/bDjJ3EU The Blob Keyboard prototype emerged during a UX crisis for iPhone team (their software keyboard just didn't work at all, fingers being too big, and the Newton failure loomed over them), highlighting how innovation is rarely a straight path. It was developed on a tethered touchscreen display codenamed "Wallaby". To make this simulator as authentic as possible, I referenced images from Kocienda's book and even got direct feedback and guidance from Ken Kocienda himself on Bluesky. What to expect (or… what not to expect): This is a reconstruction of a very early prototype with limitations reflecting that specific moment. The goal was to test first if typing with accuracy was even possible, as all the rest was moot if it failed! It's NOT QWERTY: They were still hoping to get us out of QWERTY, but then familiarity won. No Backspace: You can't delete. No Cursor Movement: The text field is just a simple display. No Caps or Numbers: Only lowercase letters. No Smooth Animations: Keys just "pop" instantly when pressed. Kocienda noted that your eye fills in the gaps, giving a sense of movement. Best Experience: While it works with a mouse/trackpad on desktop, it's designed for touchscreens to better replicate the original Wallaby hardware interaction. Use it on your phone! This project aims to provide a tangible glimpse into a turning point moment in iPhone development and the iterative nature of design. It's like stepping back in time and trying out that early demo on Kocienda's desk. I would love to hear your reactions and thoughts on experiencing this piece of UI history! What other significant prototype do you wish you could experience? April 5, 2025 at 11:50PM

Show HN: Clawtype v2.1 – a one-hand chorded USB keyboard and mouse [video] Written in Rust (embassy), running on a SparkFun ProMicro RP2040 board, with an MPU6050 gyroscope. Based on the Chordite idea from John W. McKown ( https://ift.tt/SbukKwW... ). Intended for use with XR glasses I recently bought. Currently my typing speed is still rather slow, but my skill is graduably improving and at a noticeable pace, and I can and do some vim coding in my hobby time. I plan to try and do a wireless (BLE) version next, hopefully running off a single AA NiMH battery.

Show HN: DuckDB Powered SQL Editor https://ift.tt/C139UDO

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 01:40AM

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

Show HN: I made an online free tool site Hi HN! I've created [UFreeTools]( https://ift.tt/mwQeqSv ), 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/mwQeqSv ) https://ift.tt/mwQeqSv April 4, 2025 at 11:26PM
