sure genAI can help write the thing, but does it feel any satisfaction in expressing itself? the optimistic thrill that someone might read it? the satisfaction of crossing it off a to-do list?

"internal family systems" therapy is no joke, and if you pick up a book on it and go through some exercises without a trained therapist to guide you, it can seriously fuck you up. don't ask any of my parts how they know. they are all busy screaming.

It is not a stretch at this point to say that, if you are using a Ring doorbell, you are an ICE collaborator.

Amazon readily provides data to LEOs and ICE.

Don't want to be an ICE collaborator? Then don't use Ring.

It remains a great modern tragedy that a revolutionary and cheap gene editing tech w/ obv applications in medicine and ag was discovered w/ public grants at public universities 13 years ago, and they've been in a pissing contest ever since to exclusively license it for $100Ms.

yes, but. you also need to be mentoring politicians who can step up, help you now, and eventually take your place.

I've been mapping the companies impacted by the AWS outage on October 20th, and trying to find the secondary interdependenciesβ€”when companies or services that other companies rely on go down from the outage (e.g. Slack).

This is just a snapshot, here’s the interactive version: www.thevoid.community

They 'hallucinate' 100% of the time. Sometimes those hallucinations happen to be correct.

Why are we so bad at vetting people before they launch a campaign? Like, "does have nazi tattoos?" "did some racism on reddit?" seem like easy things to check.

I'm optimistic that at least a few of those companies will change how they do things after this. We usually get one or two big ones moving in the right direction post-catastrophe.

Prove me wrong, internet! I'd love to hear from anyone from one of the companies impacted by today's AWS outage who works in the Reliability space.

AWS outage hits much of the internet, impacting a long list of websites and apps, from Reddit to McDonald's Reddit, Pinterest, the McDonald's app, Snapchat, and Zoom are among the services that rely on AWS, which suffered a major outage today.

I know ~twenty companies that do regional/datacenter failover fairly well. There is a cost to downtime. I'd be surprised if the companies on this list www.fastcompany.com/91425038/aws... didn't just lose more money than they would have spent on a failover strategy.

As our dependence on digital infrastructure deepens, more lives are increasing impacted by the reliability of that infrastructure. We all depend on it, and inevitably, that infrastructure will fail. How quickly and effectively we can recover when that occurs is the key to moving forward.

Every business that was impacted by this outage today should be responding in the same way. If your business went down because US-East-1 went down, that's a choice.

Christmas of 2012, AWS suffered a similar outage to the same region US-East-1. Netflix’s entire streaming service came down. It’s why we built Chaos Kong. We didn't just accept the disruption and move on. Instead, we changed everything about how we respond to incidents across Engineering.

It's tempting at times like this to monitor dashboards, build up defenses, and dive deep into your technical stack. You'll make better progress if you focus on the impact to your customers, dive deep into your organization's culture, and question how your org chart reinforces your style of response.
