I think what's impressive about TRON is that, visually, it's still so much more interesting than any of it's sequels. It's crazy that they tried update this digital world by making it as 'realistically rendered' as possible. It's a complete misunderstanding of the original's charm.

how do I properly order an extra shot of espresso in drinks in french, I keep ending up with like 2-3 drinks at once depending on how much caffeine I'm trying to get 🥀

I feel ok leaving the PII here because I'm confident none of these are real people. A very lazy glance at the accounts makes me think it's a LinkedIn spammer making Pakistani accounts

I got excited when I saw so many comments on our job posting and it's like 100+ of these lmao

The reason why is simple: once you "backdoor" an end-to-end-encryption it really isn't encrypted at all anymore -- the end.

As fascism rises worldwide and states increasingly deploy digital surveillance measures, a "backdoor for CSAM" quickly becomes a "backdoor for state surveillance"

This is a perennial debate: child sexual abuse material (CSAM) is now mostly spread through encrypted networks where it escapes detection.

That's a huge problem, but its also a huge problem to backdoor an encrypted chat even if its "just" for CSAM

Want to call out a really huge (and surprising) win for E2EE.

So since 2022, there's been a bill in the EU that was looking like it was fait accompli to force companies to backdoor encrypted chats to scan for CSAM

It was really bad from a privacy perspective

Headed to D.C. next week for the #INHOPE 2025 Summit! I’ll be speaking on a panel about open source tools and methods for detecting OCSEA networks. excited to learn from and collab with everyone!

If you’ll be there, come say hi 👋 let’s talk online safety and what we’re building at @roost.tools

🧵 A network of 100+ BlueSky accounts pretending to be legitimate news syndication, some impersonating BBC News, @EuroNews.com, and @Meduza.io.

Built upon ≥70 Mastodon instances, then bridged to BlueSky using @ap.brid.gy, it feels like a social-media reinvention of the Portal 🇷🇺Kombat concept.

the area around the verdon gorge took my understanding of the word "beautiful" to new heights today

I snapped this pic of Lac Du Saint-Croix after pulling over on the highway. No edits or filters. Just insanity from nature

Lac Du Saint-Croix as seen from a road above. An unbelievably cerulean lake perfectly reflects the white clouds in the blue sky surrounded by dark green trees

the Verdon Gorge as seen from the Point Sublime. A milky turquoise blue river snakes through a forested and rocky mountain landscape. The trees are various shades of green and yellow as autumn starts to kiss the region

I think it's like a mix of full time mod/t&s staff, outsourced vendor team, and some platforms do yet another version of outsourcing that uses crowdsourcing with randos

boo-liet shen 👻 @julietshen.bsky.social · 3d

don't get me started on dating apps + mod tool access, I always feel like they're not held to the same standards and discourse as social media

There are a few public examples of this too I think, might be part of the tools paper we wrote

also they (like pretty much everyone) use a 3rd party age verification software vendor! one can only be as secure as one's vendors are~

Trust & safety and content moderation are at their purest forms challenges in scaling.

Both the computational cost of scaling in terms of raw volume AND scaling accurate and consistent decisions. The latter is extra hard cause people are unpredictable and human behavior is weird and ever changing

hailey @hailey.at · 3d

an interesting note re: scaling image moderation. in the past 24 hours:

at least 500 thousand images in posts (not considering # of images, just if an image was in the post)
86 thousand avatars
500 thousand url thumbnails
58 thousand videos.

that's a lot to moderate!

For as much as Hive has built-in biases (and every model has built-in biases, because they're trained on human data and humans have built-in biases) it is, hands down, one of the more accurate commercially available services out there. This doesn't mean it doesn't suck on a few things!

Absolutely everyone knows that these available services suck at a few things! But they do refine over time (my favorite example of an image Hive in particular used to detect: bsky.app/profile/raha... )

rahaeli @rahaeli.bsky.social · 3d

The example I always use: earlier generations of Hive's model used to detect this as "adult content"! (My best guess is the "kinda human skin colors" + "rounded shadows like underboob shadows" of rows 1+2 are right where boobs would be in a closeup nude.)

An image of 8 rounded swatches, shaded like they're raised, on a color card. The first and second row are colors that could possibly be "human skin tones" and the shadows under each swatch are darker, curved, and rounded.
