I’m working on Popgot ( https://popgot.com ), a tool that tracks unit prices (cost per ounce, sheet, pound) across Costco, Walmart, Target, and Amazon. It normalizes confusing listings (“family size”, “mega pack”, etc.) to surface the actual cheapest option for daily essentials. On top of that, it uses a lightweight AI model to read product descriptions and filter based on things like ingredients (e.g., flagging pean…

Cool project!

I run tech for a reverse logistics business buying overstock from Costco/Target/Walmart and we’re building a similar system for recognizing and pricing incoming inventory. I sent an email a few days ago to see if you might be open to chatting.

It would be great to compare notes or explore ways to collaborate. Totally understand if things are busy!

I am building my own journalling app.

I know there are several out there, but I have never liked any of them, and quite frankly never trusted any of them. So far I have only been writing my journals in google docs, but the one time I used the integrations to give the ai context of my writings, it sent a shiver through my spine.

I probably sound too paranoid and naive, and I know that things like obsidian exists, but this has been a passion project since long and I am glad I have finally started spending some consistent effort on building it.

no links or name to share yet, but yes that will hopefully come soon.

I have been working on http://phrasing.app - a language learning & acquisition tool for polyglots. I’ve been using it to study ~12 languages (5 on maintaince, 2 seriously studying, 5 casually “studying”) and it’s starting to feel really good. If anyone is learning/maintaining several languages, please reach out! I’m looking for beta testers in as many languages as possible (it supports 120+). In what I believe is sti…

It sounded interesting so I wanted to try it but I couldn't figure out how to actually use it.

It says "We need to know which languages you already know. At least one language needs to be selected as a reference (some symbol) language."

I couldn't figure out how to add that, I also couldn't see that symbol anywhere...

Checked settings, profile, home ("open search" and "create expression" do nothing), create, globe icon thingy... eventually gave up.

I am about to begin a PhD in astronomy. Until last month I was working at Caltech for 3 years on code which calculates orbits of asteroids to high precision. This code is being used on several NASA telescopes now to predict when they will image known asteroids (NEO Surveyor, SphereX, maybe Roman eventually). I was allowed to open source it and I am planning on making it the basis of my PhD research: https://github.co…

This sounds like an amazing project!

I have a background in physics and ~20 years as a software engineer in the tech industry. Astronomy and astrophysics are so reliant on code these days; is there anywhere I could volunteer my expertise just to be a code monkey and help teams be more productive when working on software?

A tree cutting tool. Take photos of the tree from 6 different angles, feed into a 3D model generator, erode the model and generate a 3D graph representation of the tree. The tool suggests which cuts to make and where, given a restricted fall path (e.g. constrained by a neighbors yard on one side). I create the fallen branches in their final state along the fall plane, and create individual correction vectors mapping…

Testing this is real pain in the ass, you gotta cut real tree to see if it works in various situations :(

Not if tree cutting simulator is a VR experience

I've been thinking for years about a safer alternative to chain saws. Something along the lines of a carbide coated wire driven by an electric motor and battery. Strap it to the tree, turn it on, walk away and some minutes later the tree falls down. The main difficulty is in how to drive the wire. Using friction would create fast wearing parts. Maybe a chain could be used instead of a wire. It could oscillate back an…

Perhaps drilling in a wedge shape so it weakens the branch and it eventually breaks off naturally but it seems like more work than just a chain saw. The holes could also be used for steam treatment, enzymes [0] or something else to break it.

Working on a browser extension to make it easier to find content on YouTube that fits your interests. I watch a lot of YouTube videos and have found it very annoying that YouTube latches onto one or two topics that you've watched and only recommends that type of content over and over again. Even if you use their "Not Interested" tool, not a whole lot changes in your recommendations. At the end of last year I launched…

Crypto, Fiat, AI Ecosystem

I'm working on a new kind of financial infrastructure that combines crypto, fiat, and AI to make managing money in decentralized environments simpler and smarter. The core idea is to move beyond the traditional 'wallet' model and instead help people, especially in emerging markets, make better, more informed financial decisions using real-time intelligence and automation.

It’s designed for everyday users, not just crypto-native folks, and it focuses on things like streamlining DeFi, improving transparency, and reducing user fatigue. We’re building with scalability and user experience in mind — something that actually fits into people’s daily financial lives, not just trading.

If you are very keen on working with me, I am building a team of devs too.

Let me know what you think of this idea.
