32. Nobody knows how the whole system works
One of the surprising (at least to me) consequences of the fall of Twitter is the rise of LinkedIn as a social media site. I saw some interesting posts I wanted to call attention to: First, Simon Wardley on building things without understanding how they work: Here's Adam Jacob in response: And here's Bruce Perens,…

34. 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!

Check-pointing causes lots of WAL generation, which has direct impact on overall IO subsystem in the server, which in turn affects the performance, backup and WAL retention. Tuning checkpointer has many benefits.

48. What's the Entropy of a Random Integer?
Surely people have thought about this but I couldn't find anything on a short search. The question: let n be a random integer, say in [N,2N]. It factors as the product of p_i^a_i. So you can think of the proportion of n that is "made of" the prime p_i to be (a_i log p_i /…

55. Toma (YC W24) Is Hiring Founding Engineers
We're building the AI platform for underserved industries. LLM usage has seen a meteoric rise in the past year, but there is still a significant gap between agentic innovation and its use in the real world. This is especially true for underserved industries like automotive and healthcare, where outdated systems persist due to barriers to entry, legacy software, and high-stakes consequences of hallucinations and failure. Here at Toma (YC W24) (https://www.ycombinator.com/companies/toma), we are bridging this gap by providing a customer-centric platform to deploy and monitor AI agents, even for non-technical users. We recently raised a $17M Series A (http://techcrunch.com/2025/06/05/tomas-ai-voice-agents-have-taken-off-at-car-dealerships-and-attracted-funding-from-a16z) from a16z (https://a16z.com/announcement/investing-in-toma/) and are building the future of human-AI interactions, starting in the automotive industry.
