243. Code has _always_ been the easy part
When I joined Etsy the team was two years into a rewrite chasing a more elegant architecture (actually two distinct incompatible elegant architectures), and hadn’t shipped a customer facing feature in that time. I like to say (and it may even be true) that stopping and pivoting the team to standardizing on PHP was critical to unlocking everything that came later at Etsy. After all, no one ever has to argue about what elegant PHP looks like.

248. Data exfil from agents in messaging apps
Communicating with AI agents (like OpenClaw) via messaging apps (like Slack and Telegram) has become much more popular. But it can expose users to a largely unrecognized LLM-specific data exfiltration risk, because these apps support ‘link previews’ as a feature. With previews enabled, user data can be exfiltrated automatically after receiving a malicious link in an LLM-generated message -- whereas without previews, the user would typically have to click the malicious link to exfiltrate data. For example, OpenClaw via Telegram is exposed by default. Test any agent / communication app pairing below!

262. OpenClaw Is Changing My Life
I want to share some thoughts on my recent experience with OpenClaw. Over the past year, I’ve been actively using Claude Code for development. Many people believed AI could already assist with programming—seemingly replacing programmers—but I never felt it brought any revolutionary change to the way I work. Sure, agentic coding tools like Claude Code and Cursor have made writing code easier, but at the end of the day, I was still the one writing.
