All I have to say about this is never, ever, ever, ever say anything measured about 3B1B on this Internet. Maybe some other Internet. Not this one. When there was only one set of footprints in the sand, that was 3B1B carrying me!

@frew No that's just what Australians sound like.

So... yeah... we found a guest to talk to us about zero day markets and exploit pricing. He's... credible, I think?

(David and I tacked an "SCW: After Dark" bit at the end because he couldn't make the original interview).

@rennerocha GRU had a status-paged incident last night --- it wasn't out of capacity, but rather a deployment broke placement logic. The problem was exclusive to GRU. It'll be on the infra log this week.

I understand that this would bother if you were deploying more instances of a critical app that absolutely had to be in GRU, but it's the nature of what we do that individual regions --- we have almost 40 --- are going to experience transient issues. This was one we had a lot of control over, but >half of what we run into isn't like that.

@rennerocha @flydotio Hey there! I'm betting you were deploying in GRU last night?

@tyler I do not, but this is a super interesting subject to me and I've done some pentest work in the space. If you find a good resource, let me know.

Moss wrote a little bit of code and now it's arguably easier to give a Fly Machine access to an AWS resource than it is to give it to an ECS task. fly.io/blog/oidc-cloud-roles/

@lcamtuf @alex Now you understand deletionism.

@alex People have written to ask me about helping them set up Wikipedia pages, and EVERY TIME I have responded by trying to talk them out of it. I feel bad for the pages I started for security peeps. I even feel bad for Mary Ann Davidson. Why are you in an encyclopedia at all? Madness!

Just finished recording the next SCW, at 8:30PM on a Saturday, because our guest was in Australia, and I am extremely psyched about this one.

Michael started a Fly.io newsletter, which went out to users yesterday, and we got a flood of replies (anticipated!) and... they were... nice? People seemed to like it? Very few people accused us of being criminals? Maybe we should write more.

@ku @JustinAzoff @billseitz @tedu I'm not interested in casting main characters, sorry.

@leif There's nothing I make more often than a Caesar and I am putting this to the cinnamon test.

@rooneel I read like 5 words into this and NO IT DOES NOT MAKE A DIFFERENCE WHICH CINNAMON

@zxaos OK HOLD ON I'm not saying it was BETTER. It was clearly WORSENED by the cinnamon.

I like to think it's a metaphorical California.

I lived in California for several years. I fucking hated California. But I don't know what you do about the first dozen bars of "California Dreaming". Maybe they're right? I don't know.

Hypothesis: it is impossible to ruin a dish with cinnamon.

Further evidence: made oyakadon, thought I'd grabbed togarashi, grabbed cinnamon, still totally edible.
