Hello,

I am trying to make an anonymous chat website like Omegle. I only know Spring Boot and Thymeleaf which means I have to utilize SSR.

Has anyone made a web app using only SSR? Is it even possible?

Hello folks,

I made a very basic game named 2dBallAnimation, it's using basic vector math in order to make the Animation happen.

there is only 3 classes in the entire app:

• MainActivity.java : it gets executed when the app start
• DefaultScreenView.java : it's responsible to make the animation work by doing vector math
• V2.java : contains the x,y values of a vector and methods for vector addition, subtraction, multiplication, normalization etc..

are you Android dev or Java dev? share your thoughts about the app? feel free to give me some suggestion too.

So far I have worked on many different projects, seeing many different approaches to modern web application development including among others:

Thymeleaf, Freemarker, ZK, Angular2, Vue.js, React and Vaadin

to facilitate rendering of a UI. Obviously, there are always advantages and disadvantages and different paradigms involved.

With all the advantages that do exist with modern js frameworks, it also almost always feels like a lot of bloat and overhead to me to work with these frameworks.

More recently, I did work with Vaadin, and as a Java developer at heart, I rarely felt that much „at home“ for creating a UI.

I have to admit, it is still quite handy to know your js and css for special behaviours and edge cases, but something in me just loves working with Vaadin.

So now we can talk a lot about Performance and stuff, but Vaadin‘s simplistic approach is imho very much appealing to people who Like Java.

It might not be the best fit for everything, but it can surely get you far, and it seems that indeed quite a few companies are leveraging its advantages.

I am curious, anyone else with a positive opinion about Vaadin out there?

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.
