Having spent time building right AI setup and loops in @designwithcasa makes the amount of explorations we are doing crazy, it used to take months for larger teams to get to this amount of output... Just yesterday, was discussing some new features for the product with @surayashivji and I woke up today and she was already able to build 3 different large features that basically work and require some simple cleanup and polish.

One of the coolest projects I've worked on! I built a lot of dev tools and loops for the team last year that made it a lot easier to improve data ingestion quality at a fraction of the costs
Everyone is making AI assistants, but there is simply no product on the market like Littlebird. It's an extension of your mind, and it might change your life.

My new app ships May 15th, with one goal: helping indie app developers succeed on the App Store. It has a range of features to help you identify competitors, then find and exploit their weak spots. If you're serious about making money on the App Store, Kickstart is for you!

What did they do to @claudeai limits? I had one task working with few sub-agents, but nothing complex and I run out of session tokens in my 20x subscription🤯

Relaunching the Instaparser API today. We ran this business briefly 10 years ago before being acquired by Pinterest. Now that we're independent again, excited to give this another shot.
Today we're relaunching the Instaparser API — three APIs built on 15+ years of parsing at Instapaper: * Article Extraction * PDF Parsing * Summarization The APIs are available in all plans, including free tier with 1,000 credits per month. instaparser.com

X keeps auto translating English even though it's added as my main language in settings, it's driving me crazy

My M2 Max laptop suddenly started using fans at max speed while coding, I don't know what's going on but it's worrying me as I never heard them unless I tried playing Baldurs Gate 3 🤯

Claude leaked and now they did a wildcard DMCA notice to all @github repos mentioning claude? I just got one on my repo, which isn't the leak but a fork of the official @AnthropicAI repo 😂 I love you @AnthropicAI, but maybe a little careful with vibing everything?

Models drop every few weeks. Best practices shift with every release. Who can keep up? Building evals has become one of my favorite use-cases of leveraging LLMs. A cheap production model generates, an expensive one judges. You end up with a self-improvement loop that survives every model change. My prompts constantly change -- but I no longer guess whether the new version is better. If you're shipping LLM features in production, I think you'll find my new article interesting: merowing.info/posts/eval-loo…

This is such a wrong take 🙃 Being senior means you can evaluate and steer results better than juniors because I know what good and maintainable code looks like and we simply know what we want to achieve without having to write every single line of code. I think the debate here is more between growth mindset and fixed mindset when it comes to adopting new technology and tools, people like @steipete @KrauseFx @pepicrft and me have made career questioning status quo and adopting new ways and creating new tools to make life easier for devs, which isn't about talent or seniority as much as it's about how we think. All of us are leveraging AI daily... Also some of the hate is absolutely because of fear, a lot of works devs will become obsolete and unnecessary, teams will become a lot smaller to achieve same results or simply the ceiling will be a lot higher to compete on job market. I know this well because big part of my career has been making devs more efficent, it became a lot easier now as I can literally replace lots of dev tasks with agent loops at a fraction of costs, this is extremely enticing to businesses as it was always about getting more done and faster. Developers can adapt to new ways, but in human nature change is hard and requires time investment and it's easier to just try to spread hate and fear so that you stay in your comfort zone longer. But the thing is this revolution is not going to be stopped, you need to adapt and if you let go of your fear and learn those tools you'll understand we are in extremely exciting times, what is possible now vs 5 years ago is a complete game changer. I have been coding my whole life, and in 29 years since I started we have never been in more groundbreaking time, what it means to be programming is changing and it's coming fast, and I'm so excited to see what we can create and how our lifes are going to evolve!
Starting to realise that the pro/anti LLM debate is just a junior/senior programmer debate in disguise. Think about it. Senior devs like Ryan Fleury, Tsoding and Notch are all skeptics... but junior devs like Theo cite AMAZING productivity gains because their floor is so low.

Coming soon: XcodeBuildMCP debugging a run-time crash with the new LLDB capability. Coding agent can inspect an application at run-time, add/remove breakpoints, get stacktraces, and issue lldb commands just like a human developer would.

What I love about Codex is that it tells me what he read and what he follows when I use my rule setup, Claude doesn't do it as explicitly
