The first ever SQL debugger – runs & visualizes your query step-by-step, every clause, condition, expression, incl. GROUP BY, aggregates / windows, DISTINCT (ON), subqueries (even correlated ones!), CTEs, you name it. You can search for full or partial rows and see the whole query lineage – which intermediate rows from which CTEs/subqueries contributed to the result you're searching for. Entirely offline & no usage o…

Nice one!

https://mitte.ai — an AI image generator with focus on quality and details so you can get logos / icons that doesn’t look AI generated. it comes with Photoshop-like editor ( https://mitte.ai/editor ) so you can zoom into details and change / remove anything, or upscale, etc. I built it for myself but now there’s good amount of paying users as well.

I see that it does drawing and illustrations as well. How good it is for science illustrations, like those seen in a Physics book.

I’ve been building an Elixir app to poll RSS feeds and pipe new entries to Discord. Performance is rock solid, and it’s almost ready to release, I just need to tweak a few things (like free trial with no CC). I have a very long to do list, and ultimately want to extend it with “change detection”, e.g. notify when an HTML element on a website changes. All feedback is welcome https://feedsync.net

I've been using elixir to build an app that lets an administrator add new rss feeds, render the article titles and summaries to a single page, scroll through them and push the ones they like to a landing page as a collection to read later. Many of the sites I like don't have the conventional RSS "structure" so I have to modify my main parser and adapt it to the outliers. I'm curious, how do you adapt to feeds that don't fit the conventional RSS structure? I was thinking of just using an LLM to automate it as I keep using Claude AI to expedite the process.

https://marketingagents.net - Marketing Automation for Founders who Suck at Marketing. Open Source and Self Hostable Building this for myself mainly, but hoping others might find it useful. Still very early and building out the bear essentials, but then the hope is to keep reading marketing books and use that to improve the platform.

Nice!

A semantic music visualizer :) real-time capture of elements of music —- not tracks but true elements —- paired with time-stable frame generation for display. It likely won’t be as good as a real VJ, but I want to outshine all the visualizers which are basically a demo atop a grapheq.

Interesting, right now using LedFx for the experience

I'm looking for an open source system that has the following features. Forum for questions and answers. A section to upload video tutorials A way for experts(teacher) can upload their own series of videos. Basically looking to clone laracasts. If I can't find one, that is what I'll be working on.

This is an exciting project, Where exactly have you looked until now ?

Duckdb for streaming data!

https://github.com/turbolytics/sql-flow

I think the industry lacks lightweight fully featured stream processing solutions. I think it’s either heavyweight jvm or bespoke custom solutions

Sqlflow aims to be a middle ground , performant, fully featured, observable and supports sql

Three Kind Words (https://threekindwords.com)

It’s a small vending machine on the internet where people anonymously send a friend three postcards, one word at a time. The first two cards are unsigned, and the last one reveals who sent them. It’s meant to be a slow, kind surprise in the mail.

I shared this on HN a while back, and it gave us a quiet little push. Since then, we’ve sent 246 out of the 300 postcards we set out to deliver this year. Things have slowed down lately, but the whole thing is automated, costs almost nothing to run, and has been a lot of fun to work on!
