Do you remember the video I posted last summer of YouTuber Benn Jordan where he “uploaded a picture of a bird to a bird and then downloaded the bird picture from the bird”? So cool. Jordan is back with more data encoding tricks in his latest video, There Are Files Stored in This Video (or: How To Hide Shit In Media).

Here’s his intro, which sounds completely bonkers but he demonstrates everything he says he’s going to:

This video is a very deep dive on all of the different ways that you can covertly send and receive data. I’m going to show you how to secretly store encrypted files in music that sounds completely normal to the human ear. I even made a little web app where somebody could paste a link to a Spotify song and it unlocks a completely secret separate audio stream. I’m going to show you how you can send and receive encrypted messages via ultrasound with no cell service or Wi-Fi required by turning your phone into a modem. We’re going to be exploiting Meta’s copyright protection to store ebooks inside Instagram videos. And I’m going to show you how I stored, hosted, and shared malware inside of a harmless Facebook photo of my [dog].

This is a pretty dense video and, I’m going to be honest, some of it went right over my head. But it is also genuinely mind-blowing and makes me want to watch a Sneakers-esque hackers movie where the characters do things like:

So if you ever want to send someone a selfie over PA system in a place with no Wi-Fi or cell service, I guess we’ve made that possible today.

If you want to play around with any of the stuff in the video, Jordan coded a bunch of demos and tools and put them up on his website.

I also ran across this recently: a system that can transfer data at 190 KB/s between two phones by pointing the camera of one phone at a QR video.

Lidar and other discoveries continue to show that the Amazon rainforest was home to a “sprawling ancient civilization much bigger than researchers expected” (possibly up to 3 million people around 100-300 CE).

Hey folks. I just wanted to hop in here quickly to let a cat out of a bag: I am in the midst of moving. Not going to get into the wheres, whys, and hows right now; there’s a bigger post coming at some point about all of that. I’m excited and anxious about the transition (it’s a pretty big one), but it’s been taking up a lot of time, energy, and bandwidth that I would usually be putting into KDO.

The move is happening in early Sept, and I’m probably going to be taking some time off between now and then (timing tbd) to get everything packed & organized, spend time with family & friends before I go, and generally not run myself completely into the ground. Thanks for your patience & understanding; I’m excited to get back to focusing on the site in mid-Sept. ✌️

This is an old list but still interesting: the 12 most linguistically influential American movies since 1980. If you were compiling a list of linguistically influential movies since 2000, what would be on it?

Tressie McMillan Cottom’s reading list for fighting back against Big Tech. “Put simply, there is too much money, some of it too untraceable, giving a small group of unelected people too much power over the people.”

Emily Wilson takes another crack at a critique of Nolan’s “visually stunning, emotionally empty” Odyssey. “Verbally, we are told that people matter; visually, we are shown that they do not.”

Surfing Alaska’s Turnagain Arm (home to a twice-daily tidal bore wave) can be fun (10-foot waves you can ride for miles) but also dangerous: “You need a Plan B, a Plan C and a Plan D because no one is coming to rescue you.”

In recent years, science has been learning more and more about how central the role of inflammation is to our health. “The paradox that often makes treating chronic inflammation so difficult: It can be vital and harmful at the same time.”

Huh, here’s the trailer for a new director’s cut (of sorts) of the second X-Files movie (called I Want to Believe, orig. released in 2008) that, per Wikipedia, “will restore horror elements that were previously removed”.
