A free AIO Wordpress speed optimization plugin that includes on-the-fly image optimization, local optimizations, integrated CDN, etc., and is free.

But today I am writing documentation on presigned URLs and extending a customer's custom video processing pipeline at pushr.io instead.

I've been working on a tool called Materia[0] for managing Podman Quadlets on hosts, GitOps style and I think it's really starting to hit its stride. I just released a new version yesterday: https://github.com/stryan/materia/releases/tag/v0.3.0 . There's been a couple attempts in this space before but they usually seem to peter out after a while. I'm hoping to avoid that by staying flexible and focusing on just manag…

This is really cool! Does it take care of the 'deletion' of everything it creates if you remove config blocks/files etc.?

Yep! Everything is designed to be atomic/deterministic so you don't need to worry about materia itself causing any state drift.

I'm working on Small Transfers ( https://smalltransfers.com/ ), a payment platform that makes it very convenient for SaaS / API makers to provide a pay-as-you-go model to their customers. You can charge as little as 0.000001 USD per request. The platform uses our own system for tracking usage, which is settled through Stripe. No crypto, tokens, or wallets. If combined with subscriptions, the pricing can work similarl…

Please consult how "blik" works in Poland. It requires a bank cooperation, but it ultimately became a standard here for payments as an alternative to debit/credit card payment.

Just an old hobbyist these days. I'm finishing up the written manual portion of a "breadboard helper" for playing with (learning) electronics. The current "helper" I am finishing up gives you instructions (and an explanation) for wiring up over a dozen transistor logic circuits with the aid of a small PCB + breadboard [1]. Inspired by Forrest Mims III, Don Lancaster and the "75 in 1" style electronic project kits my…

I'm not great at electronics, but it looks like it alternates turning on the two LEDs.

Trying to document my current hobby project, but stuck in the analysis phase. I dont even know what it is. When I try to describe its purpose I get blank looks. People tend to need physical demonstrations to understand whats going on. Its not entirely new, or novel, its definitely not revolutionary, but it is a hybrid of so many things, in a very indirect sense, that its just beyond my verbiage. Not a humble brag, I…

Maybe video yourself using it / it functioning / building it / playing with it or whatever...

I'm working on Vedro, a Python testing framework as a pytest alternative without the magic and with clear output. The main idea is that tests should just be Python: plain `assert` statements instead of custom matchers, no fixture magic, and when tests fail you get readable diffs that actually show what went wrong. Tests can be simple functions or structured with steps that self-document in the output. https://vedro.i…

As someone that loves Python and hates pytest, you have my support.

(Although, I don't like using bare `assert`s in tests, but maybe you'll convince me.)

I’m building https://www.kidcarekit.com, a Rails SaaS for family-run daycare centers that still juggle spreadsheets and phone calls. It wraps waitlist management, enrollments, and Stripe billing into a single dashboard with Tailwind + Hotwire on the front, Devise for auth, and Azure Blob for logos. Solid Queue handles scheduled jobs like weekly tuition and late fee automation so owners get predictable cash flow without hand-cranking invoices, while MailerSend keeps parents in the loop.

Right now I’m polishing the onboarding flow so new centers can import families, configure their billing cadence, and connect Stripe in under ten minutes. Next up is richer analytics (occupancy tracking and revenue health) and rolling out a guided setup for late fee policies. If you’re running childcare ops or know someone who is, I’d love feedback on the workflow pain points you still feel daily.

"Google maps but for old maps": https://pastmaps.com This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS . It gets ~80K MAUs and just slowly and consistently is growing o…

Awesome work. Just out of curiosity, where do you source the maps from? In france IGN has a ton of old maps

LLMRing

https://llmring.ai

is a unified interface across OpenAI, Anthropic, Google, and Ollama - same code works with all providers.

Use aliases instead of hardcoding model IDs. Your code references "summarizer", and a version-controlled lockfile maps it to the actual model. Switch providers by changing the lockfile, not your code.

Also handles streaming, tool calling, and structured output consistently across providers. Plus a human-curated registry (https://llmring.github.io/registry/) that I (try to) keep updated with current model capabilities and pricing - helpful when choosing models.

An MCP server and client are included, as well as the ability to help you define your aliases/models with an interactive chat.

It's a thin wrapper on top of the downstream providers, so you are talking directly to them. And it also comes with a postgres-backed open source server to store logs, costs, etc.

MIT licensed. I am using it in several projects, but it's probably not ready to be presented in polite society yet.
