An algorithmic trading hedge fund. We can outperform the benchmark while keeping fees bare minimum because all our admin is outsourced to LLMs and agents. What a world we live in.

#492i made a clone of beads in rust that uses CRDTs for real time sync to coordinate a bunch of coding agents at the same time! if running locally, it's instant, for git it takes around .6s after your last action. lives entirely in git, and is like... an actual distributed database/issue system, just works, and u never gotta think about it.

#493PostgreSQL extension providing big speedups on COUNT/SUM/DISTINCT and GROUP BY for the most common data types.
I'm looking for people who have pain around slow analytics, avoiding migration from PostgreSQL, delaying pg upgrades or other big reasons to adopt something like this.

#494Skyrim mod manager for the Nintendo Switch version of the game.
It’s mainly for personal use because converting, renaming, and packing mods in bulk can be very tedious. Especially if you're always changing your mod list (which is a given).
However, once I make it more user-friendly and add a proper GUI, I’ll likely release it to the public.

#495On a mission to build the best interviewer platform with emotional intelligence, to make the conversation comfortable and engaging for the user.
Not just a chatbot, but a deep real-time knowledge capture framework with conversational AI.
Our first consumer product is Argo https://getargoai.com, but we're working on a B2B version as well.
We dug deep into what makes a conversation not just a nice chat but a deep, profound, top-notch interview, when the interviewer who neither pries nor forgets.
What makes people come to Joe Rogan or Lex Fridman and talk for 4 hours straight without feeling interrogated or experiencing conversation fatigue?
What if we had an app on our phone that helped us capture a story, filling the gap between two photos?
These are the questions we're excited about. Would love to hear what everyone thinks about conversational AI beyond the typical assistant paradigm.

#496I mentioned this a few months ago, but have made progress since - I'm working on an alternative to subscriptions for online publications. Instead of subscribing to entire publications / blogs, publishers would register their publication on this network and configure thresholds and pricing. Add a bit of code to the site and a paywall will show up, allowing readers to pay for individual articles. The prices would be minimal, amounting to less than a dollar in most cases. i.e. reading articles using micro-transactions
I know it's been tried before, but I thought I'd attack it with a few different angles - web based, no chrome extension, thresholds to help verify the article is worth it, extensive use of an aggregator to help with discovery and validation.

#499I don't have a link to share just yet, but I'm working on an LLM coding agent that can modify its own context and is given hints on when and why that would be useful.
I expect it to make it possible to not think about when to reset back to a clean session. I also expect it to be more efficient as it will clear out all the "garbage context" that only serves to "confuse" the LLM, cost more tokens, make responses slower, etc.
Once I get a working prototype, then I will test the feature by using it while reimplementing it in other open source agents to get a feel for whether it has the effects I'm expecting.

It's essentially a book progress tracker. There are many apps that allow you to add the books which you are reading currently, but not at what pace. It's simple, no complicated stuff, no AI shenanigans.
Created as I was overwhelmed by the number of books I want to read and thought it would be helpful to plan ahead.
You add a book name, number of pages and how many pages you want to read in a day. It calculates and gives you the number of days and on which date you will finish. It's also flexible to increase the number of pages so that it can recalculate.
It's a PWA for now. Still working on notifications and stuff.
