• University of Toronto ☛ There's a plague of Googlebot impersonation going on (in June 2026)

  My guess is that this isn't a bunch of different abusive crawlers who've all spontaneously decided to try forging Googlebot to see if it gets them anywhere. Instead, I suspect that this is a large scale campaign by a single abusive crawler, run by people who can afford to obtain a lot of servers at a lot of different hosting providers (or who are prepared to commit various sorts of criminal fraud on a large scale). Ironically, if they'd picked a different tactic, I might not have noticed them among the background radiation of crawl attempts. Forging Googlebot and other known big crawlers is generally sufficiently rare that I actually bother looking at my logs to see it happening.

• HowTo Geek ☛ This Linux storage feature feels like cheating once you understand it

  Storage is one of those parts of Linux that most people only think about when something breaks. You pick a file system during install, trust it with your files, and then forget it exists. It sits under everything: your OS, your home folder, your logs, your downloads, your work, and all the small mistakes you make while changing things. For years, that mostly means one thing: when a file changes, the old data is overwritten by the new data, and you move on.

  Copy-on-write (CoW) changes that bargain in a way that almost feels like cheating. Instead of rushing to overwrite old blocks, a CoW file system writes the changed data somewhere else and then updates its map. That simple shift is what makes snapshots, cheap clones, rollbacks, and smarter backups possible.
