Replacing Lombok's @SLF4J with live templates in IntelliJ IDEA

Devs who write about their work/company; talk at conferences - lots of companies in the past used to not care much about this and not value it the least.
Feels like the tide is changing: people who do this but are not valued get hunted down by companies who understand this value

Pro tip for everyone submitting to tech conferences.
Include a video of a previous talk or create one pitching your talk.
Delivery is just as important as the topic.
Don't assume the program committee is familiar with you. You need to convince the PC that your submission is of sufficient quality.

While I agree with most of the post, I don't think social media is dead. Instead it's changing to be from quantitive to filtered quality due to the slop (which existed before chatGPT as well! It's simply easier now).
Don't let the FOMO hit you and unfollow those posting things you don't like 👍

Looking forward to next year what the new regulations will bring - at least DRS will be gone.
