RankPic ( https://www.rankpic.info ) is an app to help users crowdsource their best photo. I've been building over the past 3 years & it's grown into a lovely community of people who help each other pick their best pictures for dating apps, professional photos etc. I've seen some pretty fun novel use cases, such as (multiple!) people using it to pick out glasses, wedding invites & so on. I recently completed a leader…

Hey Ben, this looks like a neat project/app! I'm always curious with apps like this about how financially viable it is. Seems to be a fair solution to be able to generate credits yourself by ranking and then buying more credits to get ranked, do you have any numbers or insights you are willing to share? (or have shared somewhere else before?)

Trying to leverage LLMs for creating custom lessons(from prompts)that use stuff like dev-typing simulation(instead of just copy/paste), narration, theoretical concepts and quizzes. Basic idea is to use 'AI'(yeah I know...) to increase our coding knowledge and curiosity about other languages and overall fingers memory, instead of just copy/pasting from LLMs.

I'm working on a open-source schema migration tool for tortoise-orm. tortoise-orm is a mature Python async ORM but it lacks a good migration tool. It isn't a super exciting project but it is something that people request over and over again.

I’m tinkering on pgflow – an open-source, DAG-based workflow engine that uses Postgres to orchestrate workers on top of PGMQ queues. It seamlessly integrates with Supabase (no new infra needed!) and executes code on Edge Functions using custom, serverless task queue worker. All the current and past state of all executions is stored in Postgres and can be queries with simple SELECTs and flows can be started from within the db (think: pg_cron, triggers).

I have strong focus on db consistency and Type safety between steps.

### Built so far – core SQL orchestration (state machine, retries, observability, queue management) – strictly typed TypeScript DSL + compiler that turns flow definitions into migrations – a minimal Edge Function worker that polls, executes and reports back

### Current focus I’m heads-down on a dedicated client library. It leverages Supabase Realtime to stream events and progress of each flow run back to the browser, while having strict compile-time safety for flows defined with the TypeScript DSL.

### Next on the roadmap - Fanouts for processing arrays of data in parallel, with per-item retry logic. - SQL-based conditionals/branching that leverages JSONB containment operator and step outputs

A "Postgres lock diagnostics" tool for migrations. We've been bitten a few times, by seemingly innocent migrations that ended up acquiring locks we did not expect (yes, RTFM). So I thought: what if, when you opened the PR, you had a tool that actually executed your migrations, saw what locks they acquired (in runtime) and then reported it as a comment to your PR? This would provide you with yet another data point you…

This sounds super useful. I imagine a pipeline where each migration has to explicitly mentioned which locks it will acquire (and the build failing if there's a mismatch).

I recently quit my salary job after 16 years and am consulting in nuclear engineering now.

Just curious: as a SWE, what are the prospects like in this field? What kind of background would be necessary to step in and what does the demand look like? I've always been fascinated by nuclear and it seems like a field that's never going to be not needed, but I kind of suck at physics and chemistry. Very cool stuff to see on your end, nonetheless!

There's a ton of money pouring into nuclear power right now, both fusion and fission. There are dozens of small VC-funded startups now in addition to the more "traditional" billionaire-funded nuclear startups. Each of them need SWEs to help with automating the physics/design simulations, document creation/management, plant design configuration/change management, QA compliance, construction management, experiment IT (instruments, controls, data collection, data reduction). Most companies have nuclear engineers like me who picked up some software skills along the way, but I've found it's always a huge benefit to bring in some nuclear-interested SWEs to help get things running with best practices. Some SWEs I've hired in the past felt a little isolated, but others have engaged well with the nuclear and mechanical engineers and had a great time. Be prepared for some weird fights with nuclear IT teams who are extra afraid of criminal penalties associated with export control laws.

Very nice! I ejected from the nuclear industry almost a decade ago and have played around in Healthcare/IoT/Oil&Gas/Finance software tech, but I'd love to figure out how to apply these skills to nuclear energy somehow. Also - love whatisnuclear.com! About 10 years ago, I tried my hand at creating a generalized JS-based viz system (see examples in https://github.com/ahd985/ssv ), but could never figure out a market/pa…

Thanks. I love your viz examples! Those are beautiful.

I've been collecting and digitizing vintage print advertisements and publishing them ( https://adretro.com ). I have tens of thousands of ads in the collection and it would take me many lifetimes to complete, but I've been using AI to extract and catalog the meta data. I can get through about 100 ads/day this way. One of my favorite ads, a computer from 1968 that "answers riddles": https://adretro.com/ads/1968-digi-c…
