I am developing a dataset and research tool for Algebraic Structures.

It's all very POC right now but the idea is to eventually add many improvements including documenting the Python API.

#362I'm working on a new Event Sourcing database that elevates the WAL into a first class application concept like a message queue. So instead of standing up a postgresql instance and a kafka instance and a bunch of custom event sourcing plumbing, you stand up this database and publish all your application events as messages. For the database part you just define the mappings from event to table row and you get read mode…
Neat! How does this differ from KSQL?
It was inspired by KSQL! But really KSQL isn't a database, it just gives you some sql processing. Nobody stands up Kafka and KSQL when they want database of any kind.
The difference is that I'm building a database and exposing the WAL to the application layer. What that means is that you can connect your legacy DB application and have it issuing insert and update queries which are now native messages on a distributed message queue. Suddenly you gain a conokete audit trail for your entities without brittle tables and triggers to track this. Then instead of hooking up Qlik or devezium, you can just stand up another instance of the DB, propagate the realtime WAL and you've got streaming analytics - or whatever new application you want.

#363Considering quitting my mind-melting corporate job to have the freedom of mind to pursue another attempt of starting my own business. So the decision is, what I'm working on. Background: they announced large scale restructurings last week and that could be my chance of getting some money for leaving (region beta paradox in full swing here). Anyone else?
Yes, in that I have the time but need something meaningful to build with it. Let me know if you might need a partner.

#364I am building https://www.videocrawl.dev/, an AI companion web application that enhances the video-watching and learning experience. Since I primarily learn from videos, I built this to improve my learning workflow. It is free to use.
It offers standard features like chatting with videos, summarization, FAQs, note-taking, and extracting sources mentioned in the video. We're taking it a step further by extracting relevant information from video frames and making it easily accessible.

#365I'm working on Video Clip Library ( https://videocliplibrary.com ), a desktop app for browsing, searching, and managing large collections of video files locally on your computer. It's essentially a small search engine for videos that runs locally on your laptop. Previously, the system just extracted information about whole video files and maintained a searchable list of those files. I'm putting the finishing touches…
How do you think of this work relative to other organizing systems like Jellyfin or Plex? Is the major new feature you care about the time subsection clips?

#366I am building an image gallery as a side project to play with AI coding tools. I got really far in just 2 days and plan to open source it soon. It: - Uses an encrypted badgerdb to keep track of metadata - Uses rclone (with an encrypted backend) for file storage in s3 or any backend rclone supports - Automatically indexes and generates video thumbnails and transcodes to webm to be streamed in the browser - Slideshows…
Maybe you should be friends with https://news.ycombinator.com/item?id=43529823
But for real, I've also been working on large-scale photo/video management, and the question of where to keep additionally metadata has bothered me. It seems right to want to keep it "in" the file, and so I want to write it into EXIF, or even steganography, or something.

#367Working on an email assistant that mines emails + your calendar.
Gives you context on upcoming meetings you scheduled a week ago but cant remember what it was about :)

#368I've been building mentions.us[1] - it sends you alerts when your keywords are mentioned on Hacker News, Reddit, Bluesky, LinkedIn and a few other places. For anyone who uses F5Bot, it's similar but with some extra data sources and a Slack integration. It's been a fun project. Dealing with the scale of Reddit (~300 posts/second) creates some interesting technical challenges. It's also let me polish up my frontend dev…
For the social platforms, are you hooking up to their APIs or just using Google? I'm only interested in emails and would pay a small price for that (say 5-7/month). I've signed up and added my first keyword to test.
That being said, here is an additional feature: being able to track discord/slack/telegram by providing my API key and you streaming the content of the groups I've signed up to.

#369I re-built a dance event web site one year ago with Django. The site was implemented by somebody else 15 years ago. It has 1M-2M page views per month.
Now I am building into it some features so other people can help me to run it, such as ticketing system (with AI), and statically generated copy of the site to improve availability.
I am also working on a service management tool, based on USM method. USM method is kind of "open source" version of ITIL, although it works on a different level than ITIL.

#370I'm continuing to update my already published ebooks. Apart from catching up to new software versions, it also helps to address typos and other issues found by my readers.
Last week I published a new version for my awk ebook (https://learnbyexample.github.io/cli-text-processing-awk-ann...) and today I'll start working on sed ebook.
