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: A fast, minimal and offline-friendly web playground https://ift.tt/0tK6jr3

Show HN: A fast, minimal and offline-friendly web playground I built a web-based HTML/CSS/JS editor focused on speed, simplicity, and offline access. No bloat — just open and start coding. What makes it different: Live Preview – Edit HTML, CSS, and JS side-by-side with instant feedback. Offline support – Works without internet. You can even install it as a PWA and use it like a native app. No Login Required – Just visit, code, and preview. Login only if you want to save/share. Savable & Shareable Links – Save scripts in the cloud and get shareable links. Customizable Editor – Themes, fonts, auto-format on save, layout tweaks, line wrapping, etc. Hotkey Support – Power user shortcuts with tooltips showing keybinds. Download as ZIP – Export your project with HTML/CSS/JS files separated. Ideal for tinkering, prototyping, teaching, or even building micro-tools. It’s intentionally simple and fast — more features coming soon. Try a sample snippet: https://ift.tt/j8caudx https://ift.tt/Hps6or5 April 7, 2025 at 01:55AM

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

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/0VxtrZU Thanks for looking! https://ift.tt/0VxtrZU April 6, 2025 at 11:30PM

Show HN: I made an AI Platform that gamifies applying to jobs https://ift.tt/dBJ0k5M

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/wp3D0eZ April 6, 2025 at 12:09AM
