Does anyone know if the DJ that played the fabulous donk set at #why2025 posts their sets anywhere?

Photo of a DJ wearing a horned mark in an extremely foggy environment. There’s very pink neon lighting illuminating the fog brightly and you can barely see them. It’s tough to capture the vibe of this one for the alt text.

I love the very poetic debug output on the #why2025 badge firmware

Debug output which reads:

"W (108607) HADES: Stripping PID 16 of its worldly possessions"

and

"W (108607) HADES: Unable to inform parent of their child's journey"

and

"W (108607) HADES: Task 16 escorted to my realm"

Who is playing the classic Furries in a Blender tracks in the dome near Milliways and will the set be available afterwards? #why2025

Now that’s what we like to see

#why2025 #ipv6only

Screenshot of the iOS WiFi settings pane for the WHY2025 SSID.

It shows the IP as 192.0.0.2 and Router as 192.0.0.1 indicating a CLAT is in use and the network is IPv6-mostly.

Everything I've read suggests #musl resolv.conf only supports 3 nameservers in resolv.conf.

So why does dnscheck.tools suggest that all 6 of the resolvers I configured are actually working?

😵‍💫 Very puzzling

An excerpt from https://wiki.musl-libc.org/functional-differences-from-glibc.html#Name-Resolver/DNS

It reads:

"Traditional resolvers, including glibc’s, make use of multiple nameserver lines in resolv.conf by trying each one in sequence and falling to the next after one times out. musl’s resolver queries them all in parallel and accepts whichever response arrives first. This can increase network load (this is mitigated by only supporting up to three nameservers, and can be mitigated further at the configuration level by only configuring one nameserver) but drastically improves performance and reliability of DNS lookups, especially if diverse nameservers are used."

A screenshot of the resolv.h source code with the line highlighted "#define MAXNS 3"
