5 + 1 tips for new IntelliJ IDEA users

Why IDEA? It seems like a lot of people have migrated to IntelliJ IDEA over the years. As a long time IDEA user I can attest there are many reasons for that.

Prevent Hibernate from doing N+1 selects with constructor expression

The Motivation While basic CRUD operations with JPA / Hibernate are easy, every application sooner or later needs to introduce DTO style result objects for specific use cases like projections. That is part of the deal, no OR mapper can do your homework for you. Luckily JPA gives us a way of specifying exactly what result objects we expect from a query. One way to do that is to use JPQL with its so called ‘constructor expression’ in the select part of the query.

But how did we arrive here? Hosting under custom domain In theory that’s quite easy. Once you have GitHub Pages set up your page will already be available as username.

Moving to GitHub Pages

Hosting Hugo on GitHub Pages As mentioned in my last blog post my goal was to move this entire homepage to be hosted on github pages. TL;DR: My ToDo create blog locally add content setup github pages add github action to auto deploy update DNS zone Hugo Build The straight forward thing to turn this collection of Markdown and other resources into a proper webpage is to simply have Hugo built it.

Blogging with Hugo

A NEW BLOG This is not my first blog ever. Over the years I’ve maintained and scrapped various personal webpages including weblogs. Now it’s time for another try. I want to focus my writing here on tech and IT in whatever one may consider to be the professional side - but who am I kidding, a blog is never strictly professional. Let’s see how this goes. 😉 The Tech Stack I have some prior experience with both maintaining and running Wordpress blogs.
