Show HN: AI-Driven Index Tuning With Postgres MCP Server Hey HN, Postgres Pro is an open source Model Context Protocol (MCP) server built to support every stage of the development process. It does a lot more than help generate and run SQL—it helps you make sure your application and database actually run well. Features: - Industrial-strength tuning algorithms similar to those in MS SQL Server - “What if?” tool to evaluate LLM-generated index suggestions - Works with Cursor, etc., to make changes in ORM code - Ensures safe SQL execution with restricted mode - Includes health checks to stay ahead of production problems https://ift.tt/FJfCXml April 9, 2025 at 04:06AM

Show HN: Dynomate– Fast, Git-Friendly DynamoDB GUI Client (Dynobase Alternative) https://ift.tt/28siBWE

Show HN: Dynomate– Fast, Git-Friendly DynamoDB GUI Client (Dynobase Alternative) After a bit of frustration with the existing DynamoDB GUI clients, I decided to build one. Features: 1. Request collections: Chain together multiple operations - put, query, update, and delete across tables, accounts and sessions. Use the output of one operation as input for the next. 2. Environment Variables: Configure variables once and run the same requests across different environments (dev/staging/prod). No more manual parameter swapping. 3. Multi-tab, multi-account support: Work with multiple tables across different AWS accounts, and sso sessions simultaneously. 4. Easy SSO Login: Start sso login without leaving the GUI. 5. Git sync: All requests configurations are saved locally as TOML files. Your data stays private, and you can version control with Git. I appreciate any feedback. https://dynomate.io/ April 9, 2025 at 03:24AM

Show HN: I built a Yahoo Messenger-inspired web chat app – pure nostalgia https://ift.tt/mPhnD23

Show HN: I built a Yahoo Messenger-inspired web chat app – pure nostalgia I’ve been feeling a bit nostalgic lately, so I decided to build a little web chat app inspired by Yahoo! Messenger. Right now it’s got group chat rooms. Super simple setup, no email required to register. You can create your own room or hop into one that’s already open. Room owners can customize things like backgrounds and even cursors of their room. Users can format their messages with basic markdown like bold, italics, and color texts (kind of like the old Yahoo! days). I even brought back the classic Yahoo! Messenger emoticons because… well, why not? You can try it out here: https://buzzed.chat (Heads up: it's still pretty barebones, so excuse any bugs you might run into!) I'm thinking of adding a few more features next, like: • Audibles • A buddy list so you can add friends • Private chats between buddies Before I keep building, I wanted to check in and see what people think. Anyone else remember using Yahoo! Messenger back in the day? Any features you’d love to see again? Would genuinely love to hear your thoughts and ideas https://buzzed.chat April 9, 2025 at 12:47AM

Show HN: Connecting an IBM 3151 terminal to a mainframe [video] https://ift.tt/3E1Owcd

Show HN: Connecting an IBM 3151 terminal to a mainframe [video] The IBM 3151 from 1987 is an interesting ASCII terminal. Unlike "normal" serial terminals, it not only supports the so-called "character mode", where after each keypress there is an interaction with the host computer (like with a Unix terminal), but it also has a "block mode". This means, you can send it commands to define fields for input and output on the screen (like a form to fill out). The terminal then handles autonomously all the the user input, and when the user is done and presses a special key (Enter or a function key), all the entries in the form are transferred to the host in one go. This is very similar but unfortunately not identical to the so-called 3270 terminals used by IBM mainframe computers. Therefore, I wrote a little C program to translate between the differing protocols of 3270 and 3151 terminals enabling a 3151 to be connected to a mainframe. I made a video describing a little bit the 3151 terminal and the interface program and showing how it looks like to work with the (emulated) mainframe on an 3151. The source code and Windows binary are on github for you to try out, if you happen to have a 3151 terminal. The link is in the description of the video. https://www.youtube.com/watch?v=V14ac9cRi9Q April 8, 2025 at 02:36AM
