30% less RAM and a 30% smaller base image for running a Spring Boot application? Yes, please.
Alpaquita Linux was designed to efficiently run containerized Java applications.
It's meant to handle heavy workloads and do it well.
And the Alpaquita Containers incorporates Liberica JDK Lite, a Java runtime tailored to cloud-based services:

Repeatedly, code that works in dev breaks down in production. Java performance issues are difficult to track down or predict.
Simply put, Digma provides immediate code feedback . As an IDE plugin, it identifies issues with your code as it is currently running in test and prod.
The feedback is available from the minute you are writing
Imagine being alerted to any regression or code smell as you're running and debugging locally. Also, identifying weak spots that need attending to, based on integration testing results.
>> Enable code feedback in your IDE.
Of course, Digma is free for developers.

An interesting read.
As always, the writeup is super practical and based on a simple application that can work with documents with a mix of encrypted and unencrypted fields.

It might be the language you’re writing in, the framework you’re building on, or some esoteric piece of software that does one thing so well you never found the need to implement it yourself.
The problem is, of course, when things fall apart in production - debugging the implementation of a 3rd party library you have no intimate knowledge of is, to say the least, tricky.
Lightrun is a new kind of debugger.
It's one geared specifically towards real-life production environments. Using Lightrun, you can drill down into running applications, including 3rd party dependencies, with real-time logs, snapshots, and metrics.

Slow MySQL query performance is all too common. Of course it is. A good way to go is, naturally, a dedicated profiler that actually understands the ins and outs of MySQL.
The Jet Profiler was built for MySQL only , so it can do things like real-time query performance, focus on most used tables or most frequent queries, quickly identify performance issues and basically help you optimize your queries.
Critically, it has very minimal impact on your server's performance, with most of the profiling work done separately - so it needs no server changes, agents or separate services.
Basically, you install the desktop application, connect to your MySQL server , hit the record button, and you'll have results within minutes:

DbSchema is a super-flexible database designer, which can take you from designing the DB with your team all the way to safely deploying the schema .
The way it does all of that is by using a design model , a database-independent image of the schema, which can be shared in a team using GIT and compared or deployed on to any database.
And, of course, it can be heavily visual, allowing you to interact with the database using diagrams, visually compose queries, explore the data, generate random data, import data or build HTML5 database reports.
Take a look at DBSchema

1. Introduction
There are a couple of ways to figure out the OS on which our code is running on.
In this brief article, we're going to see how to focus on doing OS detection in Java.
2. Implementation
One way is to make use of the System . getProperty(os.name) to obtain the name of the operating system.
The second way is to make use of SystemUtils from the Apache Commons Lang API.
Let's see both of them in action.
2.1. Using System Properties
We can make use of the System class to detect the OS.
Let's check it out:
public String getOperatingSystem() {
String os = System.getProperty("os.name");
// System.out.println("Using System Property: " + os);
return os;
2.2. SystemUtils – Apache Commons Lang
SystemUtils from Apache Commons Lang is another popular option to try for. It's a nice API that gracefully takes care of such details.
Let's find out the OS using SystemUtils:
public String getOperatingSystemSystemUtils() {
String os = SystemUtils.OS_NAME;
// System.out.println("Using SystemUtils: " + os);
return os;
3. Result
Executing the code in our environment gives us the same result:
Using SystemUtils: Windows 10
Using System Property: Windows 10
4. Conclusion
In this quick article, we saw how we can find/detect the OS programmatically, from Java.
As always, the code examples for this article are available over on GitHub.
