If there was one reason I liked coding in Java, it'd be AssertJ and its brilliant extensibility.

The image is an example of it from bjForth

The ability to create custom assertions makes the test code concise and read naturally.

Not a lot of information out there about running Java on k8s

I have also been looking into benchmarks between HTTP servers.

There is this but its just "Hello world"

Even though I don't use Azure, I found this quite interesting.

Hey Guys,

For my current spring boot project I have been using a @Scheduled annotation and using cron syntax for running jobs, but now I don't want to schedule jobs on holiday (based on US calendar).

So is there any approach to skip the schedule on holiday.

Thanks for your help in advanced.

When managing a database, speed and efficiency are crucial. As applications handle more data and become more complex, the performance of database queries plays a big role in keeping everything running smoothly. One of the best ways to make queries faster is by using indexes. Similar to a book’s index that helps you quickly find a topic, database indexes allow you to find specific data without searching through the entire database. This article explains the basics of indexing, how it improves query performance, and some simple tips for using indexes effectively. Whether your database is small or large, understanding how to use indexes can help keep your application fast and responsive.

Hey guys, I'm pretty new to coding and I recently learnt java and now I have to learn spring boot but there are a lot of sources when searched and it's getting quite complicated.

So is there any documentation which can help me learn spring boot.

Also thank you for all the help.

Like you can see in the linked youtube video (forward to 7:14), he is using an older version of Launch4j and using "Only use private JDK runtimes" in the JRE tab to make sure the .exe file uses the JRE we bundled along with other necessary files. But the latest version I am using (3.5.0) does not have that option.

What is the alternative option for the newer versions of Launch4j?
