When you add links to your LinkedIn profile (to your articles or other resources), make sure to also write a short description for them right in LinkedIn.
Most modern website social images are 16:9, and without a description, they look pretty sad in the LinkedIn feed.

I played every mainline entry, and I'm confident that I play four of them at an excellent level. That is thousands of hours invested over two decades.

Testing the payments feature is always a bit scary 😊
Despite the fact that my new product’s subscription costs just $1 for the first 100 users, I still test everything thoroughly and try to make it as smooth as possible.
Spoiler: it won’t be smooth in the first version😃

The main problem with vibe-coders isn’t the code that becomes unsupported right away, but their lack of competence with programming tools and approaches.
But vibe-coders are on the rise this era, so I want to create a “Vibe on Rails” video course for them.

Pretty soon, we’re going to see products with UI straight out of Iron Man.
Remember what Tony Stark was playing with in his garage? Those UIs had 3 things that were hard to implement that time:
1. Holographic UI
2. Dynamic, self-adjusting UI
3. Voice assistant integration
