$5k for a fan makes no sense- I could buy replacement fans for the rest of my life cheaper.

Probably not at those sizes. The company has been around for a long time with products that appear to fill a need, particularly with livestock cooling. Their fans are designed to move a high volume of air at a low fan speed. The ones I have seen in person around here in warehouses and manufacturing shops are very quiet. And very big.

I can’t recall ever seeing the word “thermic” used to refer to internal combustion engine powered vehicles. Cool. [adds it to vocabulary]

Praise the gods it's not "acoustic" cars yet :)

Hmm. Pangram AI detection says the piece is “100% human written.”

Really? A comment in another thread says Pangram says it's 100% AI. I just checked with the free plan, and it told me 29% AI. What I'm learning here is that Pangram may not be a reliable checker.

Thing is, I also twigged it as heavily LLM written when I read it, so. ¯\_(ツ)_/¯


I got the vibe that maybe an LLM was used for editing but the stench wasn't overwhelming.

I checked again with a longer sample—the first eight paragraphs—and, this time, Pangram said 61% human. Hmm. I think your twigging may be more accurate.

When I first moved to Denmark, I marveled at the babies in unattended carriages parked outside the grocery stores.

Such an appropriate-sounding name he has.

The Shazam app on my wife’s iPhone can identify TV shows and movies very quickly, sometimes nearly instantly. Not sure how it does that.


It is pretty neat and several resources online explaining it but it chunks the recoding and does a hash of the fft of each frame i think which reduces the data a lot. The server has a pre hashed database https://hackernoon.com/how-shazam-works-in-a-nutshell


I forgot the part about finding the dominant frequency in each chunk


TV shows are completed and in the can well before air date. It is entirely plausible that the interested party in having the content identifiable by Shazam like services submit whatever needs to be submitted for new content


I have also wondered about the possibility of media emitting some kind of hidden identifier. Can normal speakers emit noise outside of human hearing that could contain a unique id? Would not even need to be a lot of data that could be broadcast.


Yes, it's possible. Some sports broadcasts do this. The ones I'm familiar with use a high pitched tone on the edge of human hearing but still audible to most people.

Streaming services watermark the video as opposed to the audio as I understand it.

But that's for tracing pirated content back to the originating user account. It's not particularly useful (also entirely unnecessary and overly complicated) if your goal is to ID a piece of content as opposed to an account.


Live broadcasts make it hard for Shazam type apps to ID something from a fingerprint, so they need something else to help.


That's not necessary. If a service has access to the raw audio of a show, it can fingerprint each second of that audio in a way that can be matched in a tiny amount of computation even for a recording in a noisy environment.

That can't recognize what you say. But, it can ID where you are in a specific show out of zillions of hours of shows.


Notably, the caught the TV also recording and transmitting recorded audio and transcripts from the microphone.


Honestly, it doesn’t even need to be outside the range of human hearing.

A quick search for “audio steganography” should answer your question (and be a fun rabbit hole if you find that sort of topic interesting)


I know a guy who made a Shazam-like phone app that can listen to a few seconds of noisy audio and make a fingerprint that can be used to quickly ID those specific few seconds out of a pre-fingerprinted archive of an enormous amount of audio (zillions of hours of TV). Making the fingerprint requires a tiny amount of very smart code (in C with no dependencies). But, the fingerprint is not useful for understanding audio that's not in the archive.


Signals analysis is pretty refined and not THAT compute intense.


Many of them, especially the smaller hard-case versions, have a space to write date of first-use.


In the 1980s, a Seattle-area Chinese restaurant owner had a sailboat named Won Ton Sloop. (Or so I was told as I never saw the boat myself)


In the past 15 years, I have purchased five Lumix cameras including the new L10 (which I have yet to receive). I like their cameras a lot. The dedication to pursue this battle is another reason I am certain to buy more.


Unless I’ve missed it; Lumix has nothing to do with this long standing patent battle. Could you elaborate on the supposed relationship?


Lumix is a brand of cameras owned by Panasonic, the people who fought this battle in court.

Don't the Lumix cameras support 4k recording with the Apple ProRES codec? https://www.dpreview.com/news/3429948804/apple-loses-patent-...


Ah fair, I forgot Panasonic owned Lumix.

Though the lawsuits are more complex with multiple parties suing RED, of which Nikon also fought RED and ended up buying them out to win that side of the battle. On the panasonic side it was more of their cinema line of cameras rather than Lumix that was the driver (though they have trickle down)

And prores isn’t necessarily RAW, it’s just one of the variants.


....what? Lumix and Red cameras have almost no market overlap. Only one model series even comes close to Red's cheapest camera.


> Lumix and Red cameras have almost no market overlap.

Wrong, in the sense that market overlap doesn't matter. Here's an example of a Micro Four Thirds camera (system stewarded by Panasonic) that had to nerf its RAW output in a firmware update due to this patent:

> Z-CAM […] violated the famous RED patent and will pay for it soon

> The ZRAW actually stores RAW directly from Bayer sensor and not YUV as claimed (conversion happens in computer software, camera stores real linear raw). It means that they actually store real RAW on Z-CAM E2!

https://web.archive.org/web/20250906030132/http://www.person...

> ZRAW is not RAW anymore.

> After firmware v0.94.1 it's an AES-encrypted MOV-container-corrupted overXORred shit, that contains only HEVC bitstream.


I think you have your answer right there.
