8675309 is prime, and so is 8675311, so if you ever need a middlin'-large pair of adjacent primes to test your cryptographic suite, all you need is a 1980s earworm and a +2 and you're all set.
Man, everything is so bleak, anyone got a fun fact or little bit of trivia they want to share

A Cloudflare _and_ GitHub outage in one day?! Gonna be some good write-ups to dive into soon!
Also, love to the folks slogging through it to bring these services online again.

Sandwich case a wrap as hero found not guilty; jury determines government’s case a turkey, claims ICE testimony didn’t cut the mustard
🚨🚨🚨 The jury has reached a verdict. Sean Dunn, aka the DC Sandwich Guy, has been found NOT GUILTY of assault.

the fact that Sandwich Guy is facing this 'wich trial at all is evidence of subpar justice. he is a hero being put through the judicial grinder. i hope the jury wraps up a not guilty verdict without delay or loafing around

The hard part about engineering isn't the math and science. The creativity is hard part. That's why you gotta have a bottomless pit of curiosity about the world you live in and especially the people.

Sometimes software engineers over-engineer solutions due to inexperience.
Sometimes they do so because experience tells them past decisions won't be reevaluated later.

It's such a challenge to help folks recognize the value in constraining their problem space, shipping, then iterating outward.
Such a strong pull to solve it all in one go.
I would not be surprised if that tendency is exacerbated by the use of LLMs whose answers appear to solve it all in minutes.

Infosec teams: Every form you have folks fill out or ticket that needs to be submitted, reviewed, and approved, creates friction for them AND you.
That friction is an opportunity to build processes and tools that make the right thing easier to do and, crucially, auditable.

A System Initiative had a problem: they had production infrastructure in AWS that they built by hand, and they needed it to be automated. They pasted their architecture diagram into our AI Agent, and asked it to discover it. 15 minutes later, they had it all done. One shot.

LLMs will never not hallucinate. They literally work by effectively guessing what word comes next. There is always a non-zero probability it will generate an invalid response to a prompt. And that will always have profound implications on safety-critical and safety-adjacent implementations.

You do not solve for complexity. You learn to recognize its shapes and interactions. You learn to live with and within it.
