Do AI models still keep getting better, or have they plateaued? The AI hype is based on the assumption that the frontier AI labs are producing better and better foundational models at an accelerating pace. Is that really true, or are people just in sort of a mass ...

Is the #AI hype still on or have the models plateaued?

I joined the MariaDB Foundation - lefred blog: tribulations of a MariaDB Community Advocate Last Friday was my last day at Oracle. Today is my first day at MariaDB.org! Of course, this move is a big surprise for many people, but not for me, and it might not be for those following the MySQL e...

The #MySQL community manager since 10 years, Frederic Descamps , expains in lefred.be/content/i-jo... why he now quit Oracle and joined #MariaDB: more innovative, more features and most importantly welcomes #opensource contribitions.

I wouldn't be surprised to see multiple MySQL forks emerge in 2026, now that more people are realizing how bad Oracle has been as an open source project steward for MySQL.

Check out @villagesql.bsky.social, the newest #MySQL fork: villagesql.com

It's an #OpenSource venture backed by $35M from Google Ventures among others. It's a drop-in replacement for MySQL with an extension architecture. See their native UUID extension with efficient 16-byte storage as an example.

🐧#Linux is free as in free speech but most users assume it's also free of cost. However, users should consider paying for security assurance and fund software maintenance.

Declining GitHub commit stats for MySQL

Declining GitHub commit stats for MySQL

I posted this week about #MySQL's decline. Pecona also writes in www.percona.com/blog/analyzi...: "The overall trend since 2011 shows a sustained decline in the number of commits and a shrinking pool of unique contributors."

If you still use MySQL, probably time to switch..

#MySQL played a key role in the 1995-2010s Internet infrastructure. It has however declined in popularity since Oracle acquired it and many have said goodbye to it 👋👋

In 2026, anyone still using MySQL should plan to switch away from it.

Přestaňte už používat MySQL, není to skutečný open source - Root.cz Pokud vám záleží na podpoře open source softwaru a v roce 2026 stále používáte MySQL, měli byste přejít na MariaDB, jako to již udělalo mnoho jiných…

In case you are Czech, there is a translation at www.root.cz/clanky/prest...

Glad to see more translations show up!

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

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.

DEP-18: A proposal for Git-based collaboration in Debian I am a huge fan of Git, as I have witnessed how it has made software development so much more productive compared to the pre-2010s era. I wish all Debian source code were in Git to reap the full benef...
