Did you read the draft?
Time to celebrate with all authors, editors, reviewers, and readers of #SoSyM articles 🎉: Our impact factors have hit an all-time record! The 2-year impact factor went up to 3.2 and the 5-year impact factor to 2.7.
This shows the growing importance of software and systems modeling!

Shocking! When I said text should wrap at 72 columns, a student asked what a “column” is. With punched cards and fixed-width font line / dot matrix printers fading into history, the idea of a text column doesn't seem to be obvious anymore.

Correct, but verbose and unreadable ChatGPT (4o) code (in red) vs the human-edited equivalent (in green). (The hex_digits string isn't even used.) Without human code ownership our software risks degenerating into unmaintainable junk.

Monitor #opensource UML tools and see their trends, e.g.:
- Can you guess how many (active) UML tools are out there? 🤔
- And which one is the pillar of many ? 🤔
- And whether UML tools are becoming smart? 🤔
