Sometimes my husband will do a puzzle (wordle or similar) with me, and after we solve it, he will say something like "you're really smart" and honestly those kind of little things just make my whole day.

Like, mentally, the past couple years have been a struggle, mentally. It's been my hacker friends that have gotten me through it, whether they know it or not. Knowing so many people are putting their big brains toward doing things to make the world better or more interesting has helped.

Shame on Fortinet They tied their engineers bonuses to their sales team, resulting in NO bonuses to their technical workers Then had the NERVE to pour salt in the wound by sending a phishing test email about 2025 holiday bonuses. GROSS.

What's it made of? It's about 80-100% of something we call HDP. Human Designed Privacy. And well, it's pretty much what it sounds like. A privacy focused app framework built for humans, by humans. No vibe coding, VCs or profit motives. Sorry for the video, but We still need some space, Carol.

The Kindle version of Cult of the Dead Cow has also been updated with my additions on current #hacktivism, matching the new paperback and audio. Anyway here is a photo I took of early cDc stalwart @betoorourke.bsky.social with cDc’s @adamjodonnell.bsky.social and L0pht fellow traveler @stamos.org.

Because Veilid itself had no projected capital (by design!), and should be pretty monetary self sufficient once it's finished, everyone involved is working on it during their off-hours. But we are inviting everyone who wants to help to join in- whether it's documentation, code, marketing,etc

Katelyn 🅅 Medusfour @medus4.com · 07/12/2025
Hi! I'm one of the founders of Veilid. I'll echo what others are saying here- what we are building is incredible, it has the potential to reinvent the standard of online privacy and communication, but it's still not quite ready for widespread usage. However, everyone and anyone can help!!

it's like putting up a single screen door along an entire countries wide open border- it's only going to get used by people who want to use doors, and it can be booby trapped to hurt those who use it legitimately.

Katelyn 🅅 Medusfour @medus4.com · 04/12/2025
It seems like a good idea at first glance- however, the filter could absolutely be used to prevent ANY content from being shared, whether it's an unflattering photo, a meme, or breaking news. And while censorship is one concern- it's also very easy to mitigate the filter if you know it exists.

Katelyn 🅅 Medusfour @medus4.com · 04/12/2025
They've implemented an image hash filter which allows users to add images. It prevents upload of media deemed "private or intimate", but has no oversight or means to oversee what images are added to the filter. So it could censor legitimate content

The sad truth is that you can't solve human problems with tech- and you can't always solve tech problems with humans. Nuance doesn't translate. There's ways around this gap, but they're not easy to find a balance with. There's no single step solution for this.

Katelyn 🅅 Medusfour @medus4.com · 02/12/2025
But- to be fair, they made an honest try at it, which is more than most platforms, and used literally the only org that is fighting this form of abuse using tech. They're overthinking this, but I think the Bluesky team is under a microscope here, and so ofc they're overthinking it.

Katelyn 🅅 Medusfour @medus4.com · 02/12/2025
Sigh. Yes, I know about the moderation choices Bluesky has been making regarding NCP/NCII. Yes, I know about the massive flaws and potential for abuse that their decisions have.
