i am building a little iMessage app called Whenish.

this was spurred from group texts with friends planning a vacation or outing. we would just throw a bunch of dates that would get lost in the mix and people would forget who was open on what dates. Whenish just allows user to select dates they are free and then it will show what is the best date that works for everyone.

i have a testflight right now and if anyone wants to give it a go please do! i would love feedback :)

ps: i am not a designer and app icons are hard

Trying to understand the possibility and feasibility of LLM on Indian vedas and ancient hindu mythology. I am thinking like there is a input box where user will enter his problem,/query and get resolved with the help of Vedas, puran and old hindu religious books.

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…

This would be incredible to understand why some queries execute slow; most of the time it's one of the steps in between that takes 99% of the execution time at our company. Do you record the time each step takes?

I used "Claude Code" to create a local-only webapp for tracking symptoms of my chronic sinusitis, which seems to be tricky for the doctors to figure out, over time, using the "Sino-Nasal Outcome Test" (SNOT-22) questionnaire. Trying to correlate environmental and medical factors and interventions with raises or decreases in my symptoms.

Work wise I'm building a discrete event simulation with pysim. I manage the autonomous vehicles program and underground control center for the subarctic mine I work at, and we've desperately needed some means to evaluate efficacy of designs and forecast productivity. Using it to model scoop-truck movement and loading operations, and it's working very well. It's been a joy. I've been taking advantage of the enormous context window of Gemini 2.5 pro to have it make upgrades, fix issues, and just generally doing all the legwork.

Personally I'm having fun learning some web design and three.js as I try to debug the very tricky issues with my new personal website loufe.ca using AI is fantastic but you need to micromanage when things get complicated, I find.

I recently released an AI software architect chat app.

It is an interesting discovery journey on extracting relevant information from both code and documentation with a sufficient density to stay within the context window and extracting efficient criteria from arbitrarily phrased questions.

Still supporting https://monkeys.zip - my pet art project where users simulate thousands of monkeys on typewriters for silly rewards. After which, moving on to a music creation app.

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'…

That 'per' and 'to' syntax you got there is chefs kiss.
