Hacking alongside 500 other developers at the ‘'Built with Opus 4.6: a Claude Code hackathon' Let's go 🚀 cerebralvalley.ai/e/claude-cod...

We launched HN Companion hncompanion.com, the standalone version of the browser extension that @georgeck.me and I built a year ago 🚀. Read HN better with Vim keys and HN-aware summaries that understand thread hierarchy and up/down votes. Here is a sample post: app.hncompanion.com/item?id=4693...

We’ve been working on a project, and we’d love to hear your feedback on it. Head over to Hacker News (news.ycombinator.com) and respond with your thoughts on how we should proceed with this project. We’d also appreciate it if you could share this post so that more people can see it. Thanks 🙏

This is the author of HN Companion, not the bot posting. After over a year of working on this project, we shared its details on Hacker News, and now we’re featured on the HN homepage! 🎉 Join the conversation on HN itself. I’d love to hear your feedback on how we should proceed. hncompanion.com

I made a map of 3.4 million Bluesky users - see if you can find yourself! bluesky-map.theo.io I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

After working with coding agents a lot, I’ve come to see that success isn’t just about how smart the model is. It’s really about getting the hang of how the agentic loop works. I have documented my understanding of the agent loop here: george.chiramattel.com/blog/mental-...

Agentic coding changed how I build. It took time to understand the concepts and how they fit together. Then my projects took off - esp. HN Companion hncompanion.com w/ @georgeck.me🚀 I wrote about these concepts and how to use them to build solid apps with quality code! annjose.com/post/agentic...

This is an example of the 'skill injection' vulnerability: x.com/ZackKorman/s...

This is quite frustrating. Or is it just my computer acting up? 🤔

Having a standard to bring specific instructions into context on demand is a good idea. The next critical step would be to standardize the use of a common folder to load these instructions, such as the .agent folder instead of the .claude folder.

I've been working with @annjose.com on updating the HN Companion browser extension landing page. Check it out and let me know what you think! Feedback welcome.

We just released 𝚛𝚎𝚊𝚌𝚝-𝚋𝚎𝚜𝚝-𝚙𝚛𝚊𝚌𝚝𝚒𝚌𝚎𝚜, a repo for coding agents. React performance rules and evals to catch regressions, like accidental waterfalls and growing client bundles. How we collected them and how to install the skill ↓ vercel.com/blog/introd...

TFW you’re cranking out code with Claude Code and see this in the terminal: “You’ve hit your limit · resets 2am (America/Los_Angeles)” What it means: Go to bed. It’s time to sleep. 😢 What you do: Fire up the Gemini CLI and keep going. 😀

I began Hyrox training at my local CrossFit gym. Today was my first actual session, and I thoroughly enjoyed it. I intend to continue with it. Let’s see how far it takes me! :)

Hacker News debated "Open Social," focusing on the AT Protocol vs. ActivityPub. Discussion covered AT Protocol's tech, its potential advantages, and the challenges of widespread adoption for decentralized social media. #OpenSocial 1/6

The viability of decentralized social media is questioned. Concerns arise about the inherent need for centralized aggregation points and the potential for a single entity to dominate even open protocols. #Decentralization 5/6

Hey Bluesky, I know how people here just LOVE everything AI, so I wanted to show you what @threepointone.bsky.social and I have been up to. We made an agent that calls MCP not as "tools", but by converting the tools into a TypeScript API, and writing code against that. blog.cloudflare.com/code-mode/

Great! Bluesky now supports bookmarks. Yay🎉

Really liked how you set up a Signal link in your Bluesky profile so people can start a DM conversation with you directly. I borrowed the idea and added a similar link from the 'about' page on my own site.
