If you did not attend Spring One, here’s a little recap for you (from my perspective).
Keynote Announcements:
The rabbit hole goes infinitely deep if you want to do latency measurements, benchmarking, and performance testing/tuning/analysis. They are very hard to do right and it is very easy to mess them up. In this post, I would like to show you a very common mistake (that is just 0.000001‰ of the tip of the iceberg) and an extremely simple solution to fix it.
I do not think it means what you think it means
In this article, I would like to show you a couple of confusing things in connection with Java Strings and give you a few suggestions to avoid issues with them. I also prepared a GitHub repo for you where you can find some code that you can use to try the examples out on your own: github.com/jonatan-ivanov/java-strings-demo.
In the previous parts (one, two, three) of the series, I showed you a simple class that has three concurrency issues and I also explained these issues. In this final post, I would like to explain the tests I wrote to show the issues in action. Please let me know if you have any ideas for improving the tests.
In the first part of the series, I showed you a simple class which has three concurrency issues. In the second one, I explained the first issue: Race Condition. In this post, I would like to explain the rest of them. By the end of the series, you will understand their basic mechanism, you will be able to identify them and I will give you a couple of advice on how to fix them.
I wrote a few tests to demonstrate two of the issues, the third one is tough, please let me know if you have any idea how can it be tested. I’m also interested if you have any ideas for improvements for the existing tests because…
…well, keep reading and you will see. :)

The goal of this example-driven series of articles is explaining, demonstrating, and testing (the fun part) the two most frequent (in my opinion) concurrency mistakes in Java (plus an interesting third one), also giving you a few suggestions to fix them.

This is the second post of a series where I want to give some tips and tricks for the Terminal/CLI.
In the first post, I showed a few very handy tools like bat, exa, multitail, diff-so-fancy, delta, prettyping and htop/gtop/vtop.
This post is going to be a little longer so buckle-up, put your helmet on, grab a … frying pan and have fun.
