I just announced the new Learn Spring course, focused on the fundamentals of Spring 5 and Spring Boot 2:


At the very beginning of last year, I decided to track my reading habits and share the best stuff here, on Baeldung. Haven't missed a review since.

Here we go…

1. Spring and Java

>> Java 9 Additions To Optional []

Some interesting stuff is definitely coming to Optional in the JDK.

>> 5 Common Hibernate Exceptions and How to Fix Them []

I like to go through these exception focused articles – they usually have new insights I can glean for when I do get the exception.

>> Managing Secrets with Vault []

Storing secret configuration data is almost always an important thing to get right in the overall architecture of a system.

It's also one of the most common question I get from readers when it comes to project configuration. So this writeup is an interesting solution to that question. Not the only solution, but certainly an interesting one.

>> Turn Around. Don’t Use JPA’s loadgraph and fetchgraph Hints. Use SQL Instead. []

A different perspective on picking the persistence solution of your next greenfield project, talking about preferring plain SQL over something higher level such as JPA.

>> 14 High-Performance Java Persistence Tips []

Some low-hanging fruit (and not so low-hanging) to improve the performance of a Hibernate implementation.

>> “Micro Profile in Enterprise Java” Announced ! [] and >> The Enterprise Java Future Is Bright: Java EE 8 MicroProfile Launched []

Big announcements in the Java EE world (seems like every week now).

>> Close Encounters of The Java Memory Model Kind []

A fantastic deep-dive into the JMM (still reading through it now). Definitely one to bookmark.

Also worth reading:

Webinars and presentations:

Time to upgrade:

2. Technical and Musings

>> Code Review and How Enterprises Can Miss The Point []

An insightful analysis of the motivations of different players in a large organization when it comes to code reviews and to getting something useful out of the practice. Well worth reading.

>> How I prepared for the NDC keynote (and other speaker tips) []

Some solid, to the point advice on speaking well.

I feel that speaking is a life-long journey and there's always a lot to learn. And delivering a good presentation is such an important skill that it really makes sense to spend time and learn how to do it well, as much as possible.

>> Learning a Healthy Fear of Legacy Code []

Here be dragons.

>> Expanding the Cloud: Introducing the AWS Asia Pacific (Mumbai) Region []

Yeah, one more region to play with, after Frankfurt.

>> Special Skills []

There's a time to study the foundations and there's a time to specialize. And while foundations are important, specialization and niching down are more and more critical today.

>> Jepsen: Crate 0.54.9 version divergence []

Who knew that the Elasticsearch data consistency problems (which are quite real) would go beyond the core product and spread to other solutions as well. It's not that surprising though.

>> Amazon Elastic File System – Production-Ready in Three Regions [] and

Elastic Network Adapter – High Performance Network Interface for Amazon EC2 []

Two important announcements of new AWS goodness in a single week.

Also worth reading:

3. Comics

And my favorite Dilberts of the week:

>> Nothing about you is normal []

>> Two good ways to avoid listening to others []

>> Did someone tell you Twitter was a video game? []

4. Pick of the Week

>> This I Believe – 25 Thoughts for Life []

Nice work as always. Just a minor thing – I think you forgot to link to this newsletter from the main site page

talking about preferring plain SQL over something higher level such as JPA. OK. There’s going to be a blog post following up on that quote only. We should stop talking about JPA as being something “higher level”, just because it’s higher up the architecture stack. Conceptually, JPA is much more low level. It allows to operate on the individual rows of your entities / tables, and manipulate them. It should be a language below SQL. SQL is a much more high level abstraction of how to generate derived relations / tables from existing ones. This can hardly be done with… Read more »
