Hello old friend
Thanks to Poznań Java User Group randomly selecting me during a meetup to get a JetBrains IntelliJ Idea Ultimate license, I started using it daily. It's not entirely new software for me. I've been using Android Studio for almost a decade now, occasionally working on side projects in the Community Edition of IntelliJ. Recently at work, I've been using VS Code and NeoVim. Quite a different IDE philosophy with the latter.
I happen to work on the backend currently, and IntelliJ is an absolute beast with built-in tools for everything you can imagine.
Next to the usual language support for TypeScript, SQL, and build configs, there are nice database tools. Data display is similar to an Excel spreadsheet, allows filtering, can generate DDL code, draw diagrams, etc. Nothing too special; other tools make this happen.
But this is just inside the IDE, so it is easy to reach without changing the context.
Geo Viewer
I noticed the Geo Viewer tool by accident.
I'm dealing with some geographic data, like areas and points. Geo Viewer works out of the box. No plugins or configs are required. At least for Postgres with Postgis setup.
It may seem like unnecessary visuals, but it's actually useful for debugging. Think about having a query that returns points from one table, inside the area defined in another one. How great it is to see the result on the actual map.
Let's put it to work
I used ChatGPT to generate data for Poland's voivodships. It's not entirely bad... They are kinda in the right places, just way too small.
Data for city locations is OK.
To visualize cities and areas on a single Geo View, I used a simple SQL view. I haven't touched SQL since university, so this is also a fun experience :D

Influenced by Kacper Koza presentation on last JUGtoberfest I started using more IntelliJ shortcuts. And turned off tabs. So far so good, my mouse is getting some rest.
