Since I keep seeing developers use ‘pretty’ IP addresses like ’1.2.3.4’ in example configurations; a reminder that you MUST NOT use publicly routable addresses that you do not control in your code.

Instead, use one of the available 'TEST-NET' IPv4 or IPv6 ranges documented in RFC 6890;

192.0.2.0/24
198.51.100.0/24
203.0.113.0/24

❌ 1.2.3.4
✅ 192.0.2.4

and for IPv6;

✅ 2001:db8::/32

Pass it on to all of your fellow developers, documentation writers, and so forth.

Full RFC for special purpose addresses;

datatracker.ietf.org/doc/rfc68

Reserved for documentation, IPv4 and IPv6;

datatracker.ietf.org/doc/rfc57
datatracker.ietf.org/doc/rfc38

Open Letter to #Meta...

Hello Meta,

It has become known you are reaching out to members of our community to hold secret meetings (1), thereby roping them into a conspiracy of silence. This is not how we do things. This is an open social media network. If you have something to say, create an account and post it to all of us.

Asking you to stop this divisive tactic, and release everyone from any and all legal covenants pertaining to #P92 and the #Fediverse.

Apparently they just announced my asteroid (yes I really do have an asteroid named after me and it's one of the coolest things that's ever happened to me!!) at the #ACM2023 conference dinner, and I'm feeling even more sad that I couldn't go in person. SIGH.

But I have an asteroid named after me :) And I can watch all the talks online, which is pretty nice. And I didn't have to fly or figure out childcare or farm-sitting (or dump it all on my partner), so I guess this is fine.

It's impossible to overstate how good a job Aaron Reed has done with his book 50 Years of Text Games.

You may have seen his excellent free newsletter. The print version is even better: well-designed, easy to browse, and full of primary source material.

And a sky update: I went outside at midnight and enjoyed a firefly flitting around, super bright stars, a Milky Way so cohesive I first thought it was clouds, and faint light on the northern horizon, because it's almost Summer Solstice.

While somewhat gratifying to see the satellite brightness models we published are correct and there are indeed bright satellites visible at midnight from here, I did NOT enjoy seeing them. I've never wanted so badly for a prediction of mine to be wrong.

Canada had a Nuclear Accident in the 50s, asked the US for help, Lieutenant Jimmy Carter lead a team out of NY.

The future President Carter, had his team lower him into the reactor.

I had no idea

I have no idea why this isn't widely known.
