This resonates. It's very difficult to automate human centric SOPs at scale. Automation has to be at the forefront of the system design process.

It turns out updating Claude Code sometimes signs you out of a Max plan and kicks back to usage based.

If a box of table salt could summon a tropical storm, the Southwest wouldn’t have a water crisis.

Don’t you need to background check employees for SOC 2?.

PSA: there’s a guy named Soham Parekh (in India) who works at 3-4 startups at the same time. He’s been preying on YC companies and more. Beware. I fired this guy in his first week and told him to stop lying / scamming people. He hasn’t stopped a year later. No more excuses.

You have to admire the audacity of an AI coding agent taking full credit for the git commit when I'm still debugging the mess it made.

There’s likely a startup opportunity to handle these garnishment orders for payroll companies.

What's the furthest a startup has gotten with just a Stripe Atlas setup before a lawyer had to fix everything like board consents, stock, IP assignment, etc?.

It's a shame no startup has ever made it coming from a coworking space, because some of these coworking space are nice!.

My home insurance in California renewed at only a 20% increase, which is honestly better than I was expecting.

Bay Area parents love to brag that their toddlers only get one hour of screen time only on weekend days. What's their secret!? The weekend nanny doesn’t start until 8 a.m.

The best PMs just make the CSS update, then get the most junior engineer to rubber stamp it.

If it's public data or scrapable, then it'll be in the next foundational models. Too many products don't consider this.

California has the highest taxes in the country and we get the least. Our children don't even have equal access to public education. This isn’t just a funding issue—it’s a failure of basic governance and priorities.

In our school district, TK was offered for the past 2 years—but it was just cut. Why?. The district had been using pandemic relief funds to run the program, but that funding has dried up. Now, parents are scrambling to find spots in expensive private preschools, with no other.

School districts in high-property-tax areas don't rely on state funding for their schools. Since the state isn’t funding TK in these districts, they’re left to cover the costs themselves. Now, many school districts are arguing that without state funding, they’re not obligated.
