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.

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.
