Today I learned: `/usr` stands for “universal system resources” not “user” `/dev` stands for “device” not “development” Had no idea.

Serdecznie zapraszam 😉

Working with #SpringBoot application.properties dolszewski.com/spring/spring-…

Learning technical skills is the easiest part of software development. Being compassionate to other team members is more important. Any gr8 developer can do a silly mistake on a bad day!! Technical excellence is required but being compassionate is more important for team success.

Debugging is like an onion. There are multiple layers to it, and the more you peel them back, the more likely you're going to start crying at inappropriate times.

In case you missed the last #SpringBoot post

To make it simple, you can think of the #JavaScript Promise as of an oven. #ES6 dolszewski.com/javascript/jav…

I should pin this somewhere

programming progression year 0: I know nothing years 1-2: I know some things years 3-4: I don't know what I don't know years 4-4.5: I know *everything* years 4.5-10+: I know nothing

How can serverless have server errors? Just tried to invoke a Lambda through HTTP and got {"message": "Internal server error"}

Hey d-zone, this is definitely not OK to publish one of my post without my consent dzone.com/articles/java-…, especially given we already had this conversation and I removed my consent! Wanted to keep this private, but since you don't respond to emails... 😡 #theft #IP

Complex code hides problems.

Going to write a new blog post then deciding it would actually be a good idea to build your own blogging engine is like a carpenter deciding they clearly need to forge a new hammer before they can possible knock in a nail.

1/6 Few hints 💬 that may help in writing easier to maintain Java code 📢: ✅ organise packages by vertical slices instead of layers ✅ reference other aggregates only by ids instead of type
