The TIOBE index for #Python shows it stable from 2004 to 2018 when it started to climb like crazy through the AI/ML boom. Then it hit an all-time record high in mid 2025. However, after that, it has been declining steadily. Python devs, what are your thoughts on this?

TIOBE measures developer interest, not the amount of #Java running in production. Java remains strong in enterprise software, backend systems, and Android's ecosystem. However, is hard to ignore the trend. Java devs, what are your thoughts?

Still using #MySQL? Stewarded by Oracle, MySQL has been in decline for years. Stop using it in 2026, especially if your care about the #opensource #FOSS methodology and not just the license. 👉 optimizedbyotto.com/post/reasons...

Stop using MySQL in 2026, it is not true open source

If you care about supporting open source software, and still use MySQL in 2026, you should switch to MariaDB like so many others have already done.\n

Just explored Ignored Indexes in #MariaDB. Neat way to mark indexes so the optimizer doesn’t use them while still keeping them maintained. Great to check if an index is worth dropping without the risk of re-creating it later. How do you decide when an index is no longer useful?
