Proof-of-work to protect lore.kernel.org and git.kernel.org against AI crawlers (kernel.org)
I'm sad to say that we're following the lead of many others and putting in proof-of-work proxies into place to protect ourselves against "AI" crawler bots. Yes, I hate this as much as you, but all other options are currently worse (such as locking us into specific vendors).We'll be rolling it out on lore.kernel.org and git.kernel.org in the next week or so.

Wikipedia is struggling with voracious AI bot crawlers (engadget.com)
Wikimedia has seen a 50 percent increase in bandwidth used for downloading multimedia content since January 2024, the foundation said in an update. But it's not because human readers have suddenly developed a voracious appetite for consuming Wikipedia articles and for watching videos or downloading files from Wikimedia Commons. No, the spike in usage came from AI crawlers, or automated programs scraping Wikimedia's openly licensed images, videos, articles and other files to train generative artificial intelligence models.

Discover European alternatives to popular SaaS (xwiki.com)
Let’s face it: Big Tech companies will always put their interests first. If Europe truly wants digital sovereignty, we need to stop handing over our infrastructure to Silicon Valley giants. Yet, despite all the talk, many businesses and governments still sign contracts with Microsoft, Google, and Atlassian, locking themselves into foreign control. We can’t afford to keep making the same mistake.

Issue warnings about uses of deep reflection to mutate final fields. The warnings aim to prepare developers for a future release that ensures integrity by default by restricting final field mutation; this makes Java programs safer and potentially faster. Application developers can avoid both current warnings and future restrictions by selectively enabling the ability to mutate final fields where essential.
