Someone forgot to bring Andrew Bosworth (CTO) into the fold. They’re not giving time back from efficiency gains to employees for time off.

Just building with Claude today makes me think engineers and startups need to write more detailed specs.

A week and a half ago I finished putting together my VPP home gateway. Made some important updates with a Firewalla box to monitor the kids internet usage!

No SF Standard. I don't think Jonathan Kuminga is the answer to winning the series. We need a good game from our veterans and the rotation players. We need to convert shots and up the defensive plays.

The Warriors and Rockets game is a physical one. I didn’t think it could get anymore physical. Guess I was wrong!

An administration defying the law. A conviction shrugged off. Zero consequences.
If we let them trample the rule of law now, what comes next? What won’t they try?

Prediction: Warriors tonight over the grizzlies.

I’ve been thinking a bit about this. I think the protocol and relay implementations lend themselves to horizontal scalability. Just a hunch but the db models I’ve seen are very simple so it’s likely easy to setup some very good replication with the DB tools we have at our fingers. I do kind of want to try it just for kicks.

I have a full size. They also sell them with different mechanical feedback feels. It was agonizing to choose but I’m happy with mine.

You’d have to do that at least, then restrict connections.

A spec for lightning addresses that would would work with bolt12 is likely worth thinking about. I still think there’s value in short static payment identifiers. As it stands lightning address payment identifiers depend on lnurls.

I think the LND part of my setup wasn’t responding. Weird. Going to go with a restart, then I’m gonna go read the manual. Seems ok now but maybe I’ve got to do a bit of production tweaking

#[4] I run a Hugo static site out of google cloud. The https://alanisoft.com/.well-known/lnurlp/cesar is just a static file. The callback returned by the page is a web server, albeit just a small Python program I wrote to wire it all up

Got it. I'm gonna sit-down and write a small python app to handle my lightning address payments to my node this week. I know there's a few things I can leverage for that but I've been exploring a number of the lnd apis.

#[1] I've been meaning to ask you. Is the fact that you have a lightning address setup the reason you have a lightning payment icon in the Damus app? Your nip05 .well-known and the lnurl address are on two separate domains. How is Damus recognizing your lightning addr?
