Mr. Show, "Change for a Dollar": https://www.youtube.com/watch?v=KyocQT4Vn2g

This is more useful than every other "monitoring the situation" dashboard I've seen.

The Aisle "the moat is the system, not the model" blog post comparing Mythos' results to their system's was misleading, and seemed to be an attempt to ride the coattails of attention on Mythos. It was of low enough quality that I'd want to see more details of exactly how these vulnerabilities were found.

And in Bartz v. Anthropic, the court found that Anthropic training their LLMs on books was "highly transformative."

Thanks for the details and correction.

From what I see the code downsamples video to 5 fps, so 1 hour of video is 3600 seconds * 5 fps = 18,000 frames. 18,000 frames * $0.00079/frame = $14.22. A couple dollars more with the overlap.

(The code also tries to skip "still" frames, but if your video is dynamic you're looking at the cost above.)

Jamming is a good way to make sure everyone knows exactly where you are.

I find it odd that there's a custom of blurring or obscuring exactly the thing I'm interested in when I show interest in it by mousing over it.

Since this post is a dupe, here's a video demonstrating a similar but different app I made: https://www.youtube.com/watch?v=EjH0kMEz4YY

This went from #2 on the front page to the bottom of page 2 very quickly. It's unfortunate.

Or one person types 76 pages. This is a thing people used to do, not all that infrequently. Or maybe you have one friend who will help–cool, you just cut the time in half.

You're just saying things that don't have basis in reality.

It's not something halfway critical to the operation–why would the FAA allow that? ADS-B Exchange is not run by volunteers–it's run by employees of JETNET LLC, an aviation intelligence company. Doing it yourself almost certainly gives you less information–you're not part of a global network of receivers. It almost certainly gives you less reliability–receivers in the big networks typically have a fair amount of overlap which gives redundancy your single receiver doesn't have.

It's also not FAA approved!

Why? You would almost certainly get better data with higher reliability and no effort and no money spent from airplanes.live, adsbexchange.com, etc.

It's happening again. Spoofing is in progress, rendering another image. ADS-B Exchange has blocked access to the ICAOs/hexes in question--if you try to look at their history you get redirected to the base map.

airplanes.live, adsb.lol, ADS-B Exchange, adsb.fi, etc. do not censor the data.

These receivers mostly don’t have gps and it’s very common for people to put in the wrong coordinates.

A transponder in a car is not an "aircraft station" (§ 87.5), therefore it is not covered by aircraft "license-by-rule" (§ 87.18(b)), so transmitting would be operating without a valid authorization (§ 1.903(a)). https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D...

Imagine your boss doesn’t like you looking at ADS-B sites because it’s not data from an FAA approved system but as long as you’re discreet and not actually breaking a reg they don’t yell at you. Then they come in and see that you installed an antenna, RTL-SDR, and raspberry pi in the tower.

Just because I don't often get a chance to talk about this, I'll mention that there was a malfunction/accident/bug that caused what you might call spoofed signals to go out around Long Island and New York. Really interesting case where it seems that an FAA system wasn't handling magnetic declination correctly, which led to it generating false TIS-B targets that were rotated 13 degrees from real aircraft positions, from the radar antenna point of view: https://x.com/lemonodor/status/1508505542423064578

(TIS-B is a system that broadcasts ADS-B-like signals for aircraft that are being tracked by radar but either don't have ADS-B Out or otherwise might not be picked up by other aircraft with ADS-B In, e.g. maybe they're at a low altitude.)

There have been a couple other incidents with the TIS-B system. E.g. this apparent test near Dallas in 2022 that generated dozens of false targets in an interesting pattern: https://x.com/lemonodor/status/1481712428932997122 There was a similar incident around LAX several months later.

There are non-radar towers that don't have scopes. They may have a traffic display, or maybe not. They might choose to use a public ADS-B aggregator site because it gives them situational awareness, but they don't use it to provide radar services to aircraft. That's my understanding from listening to a lot podcast episodes with air traffic controllers, anyway. I think it's an unofficial, non-FAA approved kind of thing that can make their jobs easier.

See https://www.faa.gov/air_traffic/publications/atpubs/atc_html... for non-radar ATC procedures.
