Today's 3D printing adventure: Can I 3D print a pen? Turns out, yes

From my new course "Building a SaaS with Svelte 5": Here's a preview of one of the lessons: "Adding a pricing page" joshuanussbaum.podia.com/build-a-saas...

Built a little quad copter frame in FreeCAD

"Math Mind" is a really good book www.goodreads.com/book/show/20... To summarize: The way you were taught math in school was probably wrong.

My hobby recently has been 3D modeling and printing. Today I watched a documentary about airplane construction, so I designed this rib/spar wing portion in FreeCAD:

BetterAuth plugins are quite neat. They can be used to extend BetterAuth with new authentication methods or to intercept and change how other plugins behave. You can create bothserver-side plugins and client-side plugins. 1/5

Animotion is such a great library for presentations. Thank you @joyofcode.xyz 🙏 animotion.pages.dev ✅ Re-usable Svelte components ✅ Design using CSS ✅ Animate via CSS, Svelte, or Animate.js I'm using it for a new set of videos

better-auth makes building a SaaS type app so much easier. It's basically this config, with a few more options and some HTML/CSS.

better-auth's Stripe plugin makes it easy to send lifecycle emails about the subscription:

If you have payment integration in your project, It's nice to adjust `pnpm dev` to start both the dev server and Stripe tunneling

Outline for new course "Build a SaaS with Svelte & Stripe":

New version of Stripe+SvelteKit course coming soon: - Migrated to TypeScript & Svelte 5 - Switched to better-auth - Integrated Resend for sending e-mails - More guidance on setting up Trials & Free plans - Bonus sections on Usage based billing, Organizations/Teams and per-seat pricing

svelte-french-toast is pretty nice, and easy to adjust style and placement REPL: svelte.dev/playground/c... Docs: svelte-french-toast.com

I'm, working on an update to my SvelteKit SaaS course from 2023. Starting building a new starter template.. Yesterday, I finished the login/signup pages (user bettter-auth)

svelte-stripe has been updated to svelte 5 www.npmjs.com/package/svel... - Updated all components to Runes - Migrated project to TypeScript

My go-to reply for combatting spam 😆😁

I think that being good at learning is mostly about having the mindset of a beginner. - Excitement despite confusion - Acceptance of things not working out the first time - Audacity to do things way over your head - A process of trial and experimentation

Enjoyed reading this: www.amazon.com/Four-Thousan... Lots of good ideas.

Another site built with SvelteKit: www.printables.com

Why I don't vibe code: 1. Software projects rarely fail due to low code volume. 2. More code and features won't reduce effort. 3. Messy code is a costly time killer. 4. It's easier to waste energy building the wrong thing.

I still see dev shops quoting software projects like this: - Phase 1: Setup Authentication - ... - Phase 20 (in 8 months): All the pieces come together

Launching a job board on the Svelte Society website very soon! 🥳 Stay tuned!

Playing a mp3 from an esp32 using MicroPython mp3 player module: abra-electronics.com/robotics-emb...

As much as I hate on vibe coding, there's one place I have found AI somewhat useful... For turning a rough sketch into a realistic graphic Here's an example of an idea I had for a mini AAA-battery powered multimeter:

Rough idea: A wireless multimeter over UDP Code: gist.github.com/joshnuss/cb8...

Detecting motion with an infrared beam Using MicroPython and an ESP32 Link to sensor: abra-electronics.com/sensors/sens...

I wanted to understand how a minimal ESP32 board works So I created 3 custom breakout boards with KiCad:

Soldered it up.. might add a LiPo battery, so it's truly wireless

Does AI improve productivity or damage cognitive function? MIT study: www.bbc.com/news/article...

Built a 3.3V -> 5V level shifter using an OpAmp Cause I want to run a 5V servo from a 3.3V microcontroller

Figured out how to chase away Telegram spammers 👨‍🍳 Just reply with: "Response error -47: Insufficient OpenAI credits, try again later."

Built an HTTP based temperature sensor using ESP32 & DHT11: Full code: github.com/joshnuss/esp...

TIL: Running an SSH command from Node.js:

TypeScript template literal types worked well for this:

Before integrating with another system, it's a good idea to make a list of all API calls needed and test each one out. Only after that, is it safe to write production quality code.

TIL: Using OpenTofu to setup Hetzner resources: # to view expected changes > tofu plan # to deploy changes > tofu apply

Built a "sidecar" process for monitoring Node.js. It tracks all incoming HTTP requests, any console.log's and all exceptions thrown. It stores them all in a ClickHouse DB.

Nice that you can run Lua code in Nginx:

Todays experiment: Can I run a SvleteKit app with Postgres for $5/mo? The answer is YES.

Clear writing is made by editing. Clear code is made by refactoring.

I hope their website is using Bun.js 🙏

Messed around with Rapier2D yesterday, it's a pretty cool library.

Cool 2D game by @kempf.dev using Svelte and Rapier2D physics engine Game: subak.kempf.dev Code: github.com/takempf/suba...
