One of the main challenges on dev teams with not so much experience is the cultural mindset.

Some folks think about programming and the best practices of the language used.

Sorry, when you work in a tech company, you do not program, you develop software, which is beyond the programming language.

End-to-end ownership is non-negotiable

Staff Engineers own projects from problem definition to delivery.

You are the person people ask. You manage dependencies. You align priorities.

Ownership means no hiding behind “that’s not my part”.

Just wrapped up my final cohort of Engineering Leadership in the AI Era yesterday.

Grateful to have taught this course 10 times (7 times through Maven). But I have new course ideas that demand my attention now!

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

When you start early morning, start to setup a Open API endpoint, and the URL does not display the UI correctly… and not even the AI can find out why! 🤦🏽‍♂️😅

Happy Monday anyway !

I did not create this memecoin nor do I endorse any memecoins.

This technology is being used to automate pump and dump schemes. The "community" is recruiting "investors" and co-conspirators with upfront payments and the promise of future gains by collectively exploiting each other.
It seems the crypto community has found a new way to extract money from people. They are creating tokens for popular open source projects and inviting maintainers to get in on the scheme.

Here is the email I got earlier today.

A $50/month VM can handle millions of requests. Your startup will run out of money debugging networking issues long before you need horizontal pod autoscaling
