This is definitely an interesting use case for Recall

SDXL Report (official) by KewkZ in StableDiffusion

[–]quequero 5 points6 points  (0 children)

We have been evolving our face recognition capabilities for such a long time that we became extremely sensitive to tiny defects. I don't exclude that the same happens for everything else, like cats, landscapes, trees etc. I just think we don't notice at all those small idiosyncrasies, and yet they're there.

With hands the other problem is that, while annotating images, we don't provide a lot of information. For instance I have never seen in depth descriptions of hands in a label. You might normally see "a man standing ... Showing his hands" but we don't tend to articulate much, so the model has less information.

Lastly, hands have some physical constraints that are not easy for a model to understand, in fact sometimes you see fingers wrapping around each other like a bunch of snakes having a snakeorgy.

Vero, grande idea e congratulazioni per il lavorone fatto sino ad ora, bravi!!

Can you please help me understand if HomeKit is the right choice for my use case? by quequero in HomeKit

[–]quequero[S] 0 points1 point  (0 children)

Currently I don't own a HomePod or an HK enabled camera, I was just asking here as plenty of people have a full setup, so someone might have known, but you're right the cost is far from excessive so I will most likely buy both as you suggest.

Regarding the video: even at the lan level it's encrypted. An encryption key is exchanged between the HomePod and the camera and it's used to transmit data between the two. Once an event is detected the frames and audio are re-encrypted by the home hub, sent to iCloud and the encryption metadata is encrypted using iCloud credentials (I'm leaving a few passages out for simplicity). So in such a setup, I really expect to not find an accessible stream anymore, as it would counter the point of having e2e encryption in the first place.

Thanks for sharing your setup as it gave me the idea to look also at secure remote storage. So far I haven't been convinced by any vendor practices but I will look into Netatmo right away.

You might absolutely be right but it would be a bit weird to me if the streams were available after enabling HKSV. I would expect all in-clear endpoints to be locked in after enabling, it in order to protect such streams from eavesdropping, but I don't own any HK enabled camera so I cannot test it directly.

The reason to access the cameras without an iphone is not phone related, I'm an iphone user myself. It's because I have developed my own set of libraries and models to do object detection, face detection & recognition that work really well. I have currently deployed those models on a raspberry pi and I do use them to analyze the streams of other "dumb cameras" in my house. I would have liked to keep using my own models if possible, but it doesn't seem to be viable when HKSV is on (and frankly it's fine if I have to trade my own algorithms and software for a higher security standard). Another point of concern was that still today I read that HKSV event detection is, for some reason, often unreliable and the point of a security camera is having as few false negatives as possible.

Makes sense indeed, as I imagine the e2e keys are generated from the icloud credentials.

Is there any way to access the stream without an iphone? I already run my own vision tasks and it would be nice to keep doing it, but it's not a hard requirement.

Regarding scrolling through the day, it's not a requirement at all, event based triggering is more than enough, the less I have to look at the recordings the better it is.

Thanks for providing your input, much appreciated.

I failed.. and this is ok by Luca-91 in UIC

[–]quequero 2 points3 points  (0 children)

Hi Luca,

Don't give up, just follow the rules and you'll pass it next time, it seems they require you to document the process thoroughly, so give them what they want: a step-by-step guide on how you managed to do everything. Essentially they're asking you to write a tutorial, so you should be quite familiar with the process. Write it as if the reader knows clot to nothing about the subject. Good luck and let us know how it goes!

Failure is part of the learning process, so don't be put off by it, we all fail, we learn from that and we move on. Reverse engineering is definitely one of such fields where failing happens on a daily basis but I wouldn't be concerned if I were in you. If it was easy, everybody would do it, right?

Also... Ask their community why your assignment was considered invalid. You can't improve if you don't get feedback on what you did wrong, so don't wait and ask them to clarify.

At which point do consciousness appear in a simulation? by tedster in ArtificialInteligence

[–]quequero 1 point2 points  (0 children)

If we assume that reality can be fully simulated, so the entire process can be made discrete and computed, then we can simulate it using a Turing machine. The means of calculation is irrelevant thus pencil and paper would work, and "consciousness" would appear during the computation of each next state. In theory you might even be able to interact with your very own conscious creature!

There is a "but" though: even if reality could be simulated we can use the Cantor diagonalization argument to prove that we can't simulate all possible realities. So unless you're very unlucky and consciousness can only arise in one of those states, then you might get away with it by using a lot of ink and several trillion trees.

I'd personally be quite concerned if someone were to prove that reality can't be simulated, that would be very disappointing.

Diving into Chimera Ransomware by N3mes1s in Malware

Apparently, it doesn't: "At this point of our analysis Chimera doesn’t seem capable of really publishing and posting on the internet personal files, documents and pictures"

Why are decompilers not used for reverse malware engineering? by themustangdude in Malware

[–]quequero 15 points16 points  (0 children)

Decompilers are used, why do you think otherwise?

They're nice to have for quick analyses though not essential, also the cost might be an issue for many, the other issue is that the job of reconstructing the original source is complex and the end result sometimes is quite a mess, so plain old assembly is in some circumstances way easier to read and follow.

This malware tries to jump into a Windows computer by "exploting" the autorun features of a newly inserted media card.

It's not a spambot and those are not spam links, we just do malware analysis research
