Oh my... is Gemma3 4b better then Claude 3.7?! 🤯 I ran into a basic issue with Liveview template rendering. Multiple attempts to debug it using Claude 3.7 did not work. Then I used Gemma3 4b. First try: perfect answer, issue solved. Local models are the future! #elixir #buildinpublic #indiedev

Same model, same context, different outcome? How is Cline not able to debug a simple issue in a single file, while it has all the context (file + error), after multiple attempts. When I copy/paste this in Claude on the web it fixes the bug in a single try. #buildinpublic #indiedev

The MVC architecture will evolve into MPCT in AI era: Model, Prompt, Context and Tooling. To build AI agents we basically need these 4 building blocks to rapidly iterate apps. #buildinpublic #elixir #indiedev

Where the prompt along with structured output libraries like Instructor (python) and Instructor_ex (elixir) will be like the ORM / repository pattern.

Oh, boy! Here we go again. I've stumbled upon a new project/business idea. It ticks a lot of boxes: - I know there is demand and I know for sure people are paying for it ✅ - There is (some) competition ✅ - Scratches my own itch ✅ - Close to my skills and interest ✅ #buildinpublic #indiedev

Building an Elixir app using Windsurf, Claude and Deepseek feels like using AI like it was 1-2 years ago. The difference in amount of code that is properly generated when using JS/Python versus Elixir is huge. The benefits of using Elixir are slowly fading away 🤯 #elixir

Some of the results of my - very poorly prepared - voicezap.ai PH Launch. 5th product of the day + mention in the PH newsletter 256 upvotes Converted into 506 web visits 68 (!) sign ups Not bad for a first PH launch 🤯 #buildinpublic #indiedev

I want host 2 tools on my own VPS: uptime monitoring for multiple websites and log management. Are there any open source solutions for this? #buildinpublic #indiedev

Anybody any experience building a OAuth 2.0 setup using Elixir Phoenix? The go-to package hasn't been updated in 2 years: github.com/danschultzer... 😱 #indiedev #buildinpublic #elixir

Just found out that every web visit to thinkos.app costs 0.09/g CO2. Apparently cleaner then 91% of the sites globally. So, please don't visit the site 😉 #saas #indiedev #buildinpublic #elixir

Knock out! After 10 rounds of boxing with the App Store review team, I just pushed a big update on the Think OS app to the iOS app store. You can now capture your thoughts offline. Since I don't want to sit behind a screen all day, that is kind of a big thing 😊 #buildinpublic #indiedev

Is there an email/campagn editor that let's me write my marketing email (preferably locally) and sent it using my Mailgun API keys? #buildinpublic #indiedev

@rxjdev.bsky.social

Just a thought: in the era of AI agents a lot of products are going to resolve around a) providing the right context and b) function calling. Like context for devs, context for enterprise, context for social media marketers, etc. Same could apply for function calling.

It feels as if the Apple app store review team is just making up arguments to reject my submission. They are providing feedback regarding "in-app purchases" which I don't offer and didn't configure. 🥊 Round 9 #buildinpublic #indiedev

Building an app is easy nowadays. I've learned the basic of building with React Native in under 2 days. Submitting it to the app store is ridiculously complex. 🤯 #buildinpublic #indiedev

rxj
@rxjdev.bsky.social

I'm trying to get passed the review submission process. The terms of use + in-app purchase policies appear are killing my mood already for 7 days straight. It's slow and the feedback is ambiguous and changes from review to review. Would pay for someone who can guides me through this process

I just hooked up all my personal notes to a LLM. Not sure if this is smart, but the results are really scary. Will share when I'm ready. #buildinpublic #indiedev

After "pitching" thinkos.appthinkos.app last weekend to my non-techie friends, I realised I need to up my marketing game. I myself am still not sure what I'm actually building. Is it an app that helps you to "think with insights", "think with clarity" or just a "tool to transcribe thoughts"?!

If you are answering the phone you are in your customer support or sales role. If the person on the other end critiques your product, you can always "I will discuss it with the product or development team". 🫠 😁

This simple lesson took me a few years to internalize when bootstrapping a company. It helped me tremendously with my own mental health. And it can be even a lot of fun to apply.

Just made a marketing competitor analyses for 10 competitive/alternative apps in 5 minutes using Claude Desktop and Brave Search API 🤯 I remember this took a single marketeer 6 years a go more then a few days...

Oh my! Of the 417 people I'm following on X close to 50% is already on Bluesky. I guess I'm a bit later to the party then I expected 😅

In 2024 upgrading Xcode is still a nightmare. On the positive: it gave me the time to read up on the AT Protocol from Bluesky. This protocol very well might reach further then only the Bluesky app! I'm already tinkering if I could apply it to Think OS to store notes in a decentralized way 😱

You are up to date.
