If you own a product, especially one for developers, ask yourself: what can you offer that they can't build or figure out themselves? The popular view is that anything can be built today. That's true only if your time and money are worth nothing.

So uhhhhhh… Apparently meta's muse "AI" is just straight up doxxing people to strangers on FB marketplace??? This has the potential to hurt so so many people, and I genuinely wonder how long before they roll out a fix for it.

the hard parts of building a business are - solving a real problem for real people - ignoring shiny ideas that are fun but distracting - prioritizing boring stuff that moves the needle - connecting with customers if anything, AI makes it *harder* to build a successful business

LLMs don’t write buggy code, humans with LLMs do.

BC has a new time zone abbreviation: PCT. PCT stands for Pacific Time, BC’s single year-round time zone. It replaces PST and PDT, providing a consistent way to refer to BC’s time zone in schedules, systems and communications. No falling back this November.
