I wished dealing with HTTPS on localhost was less painful. Like, couldn't the OS have a special built-in trusted cert which apps can use?

At a job interview many years ago, I was asked: "What's the difference between SQL and MySQL?". Still trying to figure out whether that question was ignorant or ingenious.

What to focus on during a code review? Don't waste your time with automatable formalities like code style. Rather spend your review budget on those aspects which will be hard/expensive to change later on. The "Code Review Pyramid" provides some guidance on what to look for.

"Good code documents itself" is one of the most damaging takes in software engineering. Code itself won't tell you about the decisions and rationale behind it, nor about about higher-level structures and abstractions. All this needs elaboration in documentation.

"Google Best Practices for @java Libraries" Lots of great advice in these docs for library authors, e.g. to have a well-defined minimal public interface, avoid split packages, and much more. That's a really useful resource 👍! jlbp.dev

⏱️ Just ten more days until the release of @java 17, the next version with long-term support! To shorten the waiting time a bit, I'll do one tweet per day on a cool feature added since 11 (previous LTS), introducing just some of the changes making worth the upgrade. Let's go 🚀!

The biggest problem of #Java is poor perception. It's technically super-solid, but too often folks discard it based on misconceptions or information outdated years ago.
