Course – LS – All

Get started with Spring and Spring Boot, through the Learn Spring course:


1. Spring and Java

>> Feeding Spring Boot metrics to Elasticsearch []

After low level system data, the next family of metrics you want to start tracking and monitoring are JVM level metrics. Here’s a good way to go it with the ELK stack.

>> Reflection vs Encapsulation – Stand Off in the Java Module System []

A quick and practical intro to the various mechanism that are going to power the module system in Java 9.

>> Creating Maps With Named Lambdas []

Interesting way to create a Map.

>> Spring Boot and Thymeleaf: Reload templates and static resources without restarting the application []

Years back, we always had to restart the server/redeploy the app for minor changes. Of course that’s no longer the case now – which has a significant impact on our speed of rolling work out.

If you’re working with Thymeleaf in a Boot app – here are a couple of ways to do exactly that – changes with no restarts.

>> Hibernate Envers – Getting started []

There are a few different ways to slice implementing audit logic with Hibernate – and Envers is definitely an interesting solution to the problem.

>> Making Spring Boot application run serverless with AWS []

Very interesting writeup showing how to transition a Boot application to run servlerless on AWS. I definitely need to give that a try to get a better understanding of what it can do.

Also worth reading:

2. Technical

>> Time in distributed systems []

As I started to split my own implementations and very carefully joined the microservices bandwagon (or train) – I very quickly found that I need to relax my definition of time for each service.

That is if I wanted to be able to trace a single request through the system and still make sense of it.

This is a quick writeup all about that.

>> Data Science up and down the Ladder of Abstraction []

A long piece worth reading if you’re passionate about data science, Clojure – or both.

>> Sharing Experiences from a Microservices Journey []

I’ve been doing a lot of CQRS, Event Sourcing and microservices in the past couple of years, so naturally this article was quite an interesting read – well worthy if you’re doing any of these.

>> How Chrome’s buggy content security policy implementation cost me money []

Beyond the “money” thing, there’s a lot to glean from this piece about Content Security Policies and the way browsers chose to implement CSPs.

Worth understanding if you’re building stuff for the web.

Also worth reading:

3. Musings

>> One year as a Developer Advocate []

Hibernate should have obviously done this a long time ago 🙂

>> Reactive Streams and the Weird Case of Back Pressure []

If you’re working with and ingesting a large volume of data, back-pressured async stream processing is a godsend.

This is a good intro to how the standard came to be – and a very interesting read.

>> The Journeyman Idealist: Architect of Programmer Paycuts []

This writeup is definitely good for some perspective on the way we all work and creating value. Some solid podcasts recommended in here as well 🙂

>> Rewrite or Refactor? []

To be or not to be? That was THE question for a long time, but no longer 🙂

Now, it’s to refactor or rewrite – mainly because that decision has the potential to literally put a business under.

>> Clean Code: what is it? []

I always find that, no matter how much I think I understand a concept, I don’t fully grok it until I have to sit down and actually define it. It always turns out to be more difficult than I expect it to be.

Also worth reading:

4. Comics

And my favorite Dilberts of the week:

>> The Ugly Truth []

>> You don’t know how low my ambitions are []

>> Are we polite now? []

5. Pick of the Week

>> Worrying is self-fulfilling; what to do instead []
