Thoughts on Java, Part 1

Tracking my thoughts and understanding of Java as my understanding grows.

Impressions

Words that are jumping out include 'structured' and 'arbitrary'. I've already written about my first impressions of type-safety, but this moves into new territory, like the different classes of strings.

Progress

It's harder to predict how long tasks will take; Some things are very similar in implementation to Ruby, but with strings it's Apples and Oranges. Some strings are mutable, some are immutable, and trivial tasks like pushing strings to arrays has made me aware of the StringBuffer class, which does not return a string equal to that of the String class.

Closing

Working with Java has meant dealing with things I didn't know existed, so assuming that the OO similarities make up for being static, typed, and compiled was wishful thinking. I'm starting from the beginning again, only the beginning is harder here. It's a lesson in humility.
I'm learning a lot though, and I think that once the basics are down, things will seem clear, and I'll be a better programmer for having learned to do it this way.

Great read:

Is it Time to go Back to the Monolith?

History repeats itself. Everything old is new again and I’ve been around long enough to see ideas discarded, rediscovered and return triumphantly to overtake the fad. In recent years SQL has made a tremendous comeback from the dead. We love relational databases all over again. I think the Monolith will have its space odyssey moment again. Microservices and serverless are trends pushed by the cloud vendors, designed to sell us more cloud computing resources.

Microservices make very little sense financially for most use cases. Yes, they can ramp down. But when they scale up, they pay the costs in dividends. The increased observability costs alone line the pockets of the “big cloud” vendors.
