I am speaking up in support of Chris Krebs We all need to

Here's my blogpost in support of Krebs. It's different enough from those by @stamos.org or @k8em0.bsky.social that it's worth writing, though the conclusion is much the same.

Working with Chris Krebs and getting to know his wife Emily and their family has been one of the great honors of my life. The attack against their family should be condemned by all.

I have written a post about what is happening to them here: www.linkedin.com/posts/alexst...

one of my favorite parts of vibe coding is that it brings one of the core parts of programming - randomly changing things until it's fixed - to everyone

“ThErE Is nO EvIdEnCe oF AnY ThReAt aCtOr aCtIvItY” said the clowns at @lastpass.bsky.social in their many, many updates trying to downplay the severity of this breach.

If you’re using LastPass in 2025, you’re being grossly negligent.

This example of writing from DeepSeek's r1 model is incredible. It actually persuaded me that the chat interface is more than just a rough first draft of a UI.

Also, "the demon stirs"? I could read this all day.

Getting silly with C, part (void*)2 They won't be able to find bugs in your code if they can't figure out how it works.

TIL that C function definitions have an implicit semicolon after them, which enables you to put a function declaration in the for loop control block.

Reporters, this is a story worth covering. It might not be as glamorous as high-profile hacks, and it might not attract as many clicks, but it’s important. The quiet adoption of HTTPS has improved online security for billions of people, and it deserves attention.

sean cassidy : Plural gTLDs are evil

And plural gTLDs make this even worse: www.seancassidy.me/plural-gtlds...

The problem here is that humans want human-readable and unique names to disambiguate entities, but there are too many entities to do that all in one TLD. Having all of these gTLDs makes that easier, but identifying the correct website much harder.

LLMs are going to take a lot of security industry jobs. We're already starting to see it, and in 2025, and especially 2026, it'll be all we're talking about.

If you're using Telegram? Don't.

At the moment, Signal (signal.org) is the most secure fully mature messaging app that's out there. It's what CULT OF THE DEAD COW uses for our intra-herd conversations, as well as being pretty much the Gold Standard in the information security community right now.

i will never forget the time, i, a newly minted freshman in college, was in the supermarket and asked if a guy was on line (for checkout). and he said, "you mean, like, on the internet? oh here in rochester we actually say in line rather than on line."
