So I upgraded my PostgreSQL database (around 1.2TB in size) from version 17 to 18 on ZFS on Linux yesterday.

Thanks to OpenZFS' block cloning feature, pg_upgrade can use reflinks, speeding up the process massively.

I wrote about this on the PostgreSQL users mailing list in case this might be interesting to someone, and one of the PG devs answered with additional insights about ZFS reflinks, their syscalls and some additonal tooling tricks with PG on CoW filesystems.

Gotta love OSS!

RE: norden.social/@wackJackle/1155

Joscha Bach, der hier einen Zivilisationsbruch nach dem nächsten im Austausch mit seinem Geldgeber Jeffrey Epstein macht, spricht dieses Jahr _wieder mal_ auf dem Chaos Communication Congress btw

EDIT: Scheint gerade aus der Planung rausgenommen worden zu sein. Evtl. wars jetzt sogar dem CCC zu viel (Dokumentierte Deals mit Epstein als der schon verurteilt war hat ja nicht gereicht)

Behind the complaints: Our investigation into the suspicious pressure on Archive.today

Some time ago, we were contacted by a group fighting against online CSAM, demanding that AdGuard DNS blocks the Archive.today website. This was only the beginning of a much larger story…

0.7 brings a redesigned system with much better performance. We've moved from generating on-demand to storing them as they happen, which makes the notifications endpoint about 60% faster. We've also added response compression (though if you're using a reverse proxy, you probably had this already).

More notably, Hollo 0.7 implements Mastodon's v2 grouped notifications API. Notifications like favorites, follows, and reblogs targeting the same post or account are now grouped together server-side, reducing clutter. Clients that support the new API (introduced in 4.3) will show cleaner, more organized notifications automatically.

Hollo 0.7 is still in development, but we're excited to share it with you when it's ready!
