Both the driver and the man are in founder mode.

The man who got hit by a bus and immediately went back to the pub is strong! Beer is very important.

Send out enough cold emails, and you’ll start to feel the cold yourself.


Seriously, a recruiter claiming they got 3,000+ resumes doesn’t mean they have 3,000 interested candidates. With AI doing the job applying these days, that number’s inflated. No need to be so mean when most won’t even see the automated emails sent out.

I am pretty sure for lots of tech companies, it is 20X more times the value you are paid.

Reality check: Your job is at risk if you don't produce at least 3 times the value you're paid. A 100K salary requires 300K in value. This ratio is only growing as technology improves. If you can't move the needle, It's time to move your seat.



I like how everyone on X shares this as an insane launch. The engineering team simply updated the model version from claude-3-5-sonnet-20240620 to claude-3-5-sonnet-20241022.

Anthropic just announced Computer Use It allows Claude to control your computer screen based on a prompt and take actions on your behalf The use cases in agentic coding with automated debugging, customer support, and education are going to be INSANE



claude-3-5-sonnet-20240620 => claude-3-5-sonnet-20241022


In your 20s, lifting at the gym is all about checking out the scene. In your 30s, it’s just you, your breath, and counting reps—simple as that.
