My project is an ongoing one of self improvement. I've spent most of my adult life working on technical stuff, and it's taken a bit of a toll on me. I quit working about ~20 months ago, started a low-carb time restricted eating regime, lost ~230 lbs, have been doing 15-25 hours of cardio a month for the past year, started going to therapy, got an ADHD diagnosis, read a bunch of classic literature (Middlemarch and The…

I was diagnosed with ADHD last year, and am curious as to what you've learned in your time. I'm taking 40-50mg methylphenidate hydrochloride (Ritalin) daily and working a hybrid web developer role. I'm trying to increase my reading of literature and begin writing, but I find myself just watching YouTube/browsing Reddit and HN.

230lbs is wild. Great job :)

I launched my web-based notepad calculator, https://numpad.io/ , a few years ago. Right now I'm working on a version 2 that has user accounts, multiple documents, markdown support, and document exports. Everything is local-first and it uses CRDTs to sync documents. It looks like this: https://i.imgur.com/Plk1DQ4.png the calculator is mostly the same for now, with a few improvements. It's unstable right now, so I don'…

I see this on the example: 6 ft 2.0000000000000000004 inches

A series of pulpy short stories, sort of a Dark Americana / weird fiction thing. Noir, magic, existential dread, horror. Warming up for a novel in a completely different genre but I wanted to iron out some of my own shortcomings and stretch some muscles before I write yet another 100k words on a project I'm unhappy with.

This sounds fascinating! I'm a big fan of weird fiction. If your stories are published or shared anywhere when complete I'd love to check them out.

A v2.0 update for my biology education app. I'm adding the ability to walk around cell models with billions of atoms on the Vision Pro.

I'm designing the content browser right now. I'm trying to achieve something really immersive like Apple's new Spatial Gallery app.

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 :(

I got filtered by the Ent arc of LOTR and dropped the book.

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…

God tier filtering. Do you mind sharing how you integrated AI into the filter system? Your "flagging peanut butter" example also makes me wonder if the LLM is tagging the product with a large number of attributes on each run so it's not prohibitively expensive.

Recently I’ve pretty much replaced searching Yelp or TripAdvisor with a combination of Instagram Reels/TikToks and Google maps for travel and food recommendations. I usually just save a lot of places that I have to dig through and watch again to dig through and add to my saved Google maps lists. Because this takes me a fair bit of time when preparing for a trip, I decided to automate part of it by building a pipeline to “watch” the video for me by getting the audio and video frame data and taking into account key POIs that I then export out to a note. Later I plan to also integrate this with other travel or food tracking software like Wanderlog, Google maps list, or Beli eats. So far it’s been working well, but def expensive (so thank god for free GCP credits haha)
