Yea, I could have used a better word choice. I was thinking about the domains here in the generalized sense such as signal processing and wireless communication being applicable to the domain of artificial intelligence. In reality, you are correct that it's all tied together under of domain of applied maths or computer science.

I can't help but think of orthogonal frequency-division multiplexing and it's use in encoding data on multiple carrier frequencies, and it makes me wonder what other parallels we will discover between digital transmission technology for cross-domain stuff like this.

I hate when I find a cool AI project and I open the github to read the setup instructions and see "insert OpenAI API key." Nothing will make me loose interest faster.

It's pretty annoying that every project like this lately is just a wrapper for OpenAI API calls.

Yet another OpenAI API project. Set it up for containerized local LLM.

Why put it behind a login? There is no easier way to guarantee I won't even try it.

Religion is a cancer that really needs to be cut free from humanity, not co-mingled with technology and the modern world. It's disgusting to consider the sheer number of people that have been killed in the name of fictitious "gods". Religion is a tool used by the wicked at almost every point in history to justify their greed, hatred, violence, and unjust actions as being the will of some higher power that only they can hear. Even now, far right nutjobs are again co-opting religion to push their vitriol into the minds of the weak.

The fact you equate that experience as being anything close to what Gen Z is experiencing kinda proves the point of the post.

Unless you went to the most expensive school possible, it would have cost you a couple hundred hours of work to afford your education. When you graduated, you were most likely able to afford to either buy a home, or live on your own using your income alone, right out of college, if not shortly afterwards.

All of those experiences are not possible for the vast majority of Gen Z individuals. For Gen Z to pay for four years of college they would have to work over 15,000 hours over 4 years. That's about 73 hours a week at the average pay rate in the US. There is nowhere an average income can afford someone to live alone. Homes your generation got for 20 to 50k are now in the 500K+ range.

So yea, I 100% agree that boomers will never understand.

Mistral has already scrubbed their commitment to open source from their website, doesn't look good.

They already have removed their commitment to open-source. It's not looking good.

We are going to hit a point soon where even creators won't be able to spot all the borrowed animation elements due to the black-box nature of generative AI models. I imagine it's going to be like the Akira bike slide but for everything.

Things lifted wholesale from training data but plastered together to create new works will leave us in an uncanny state of semi-permanent déjà vu where our little pattern matching blobs constantly chirp out subtle connections.

Binwalk was able to detect the embedded zlib compressed data in all three of your example images. You should give https://github.com/JustinPack/XOR_LSB_Stego/blob/main/Paper/... a read.

While it's a neat read, most the links are dead or the products unavailable.

Hey there. I must have missed the section that handles encrypting the session key, my bad.

It's more the struct method of embedding though that I was emphasizing. Structured encrypted data has high entropy which can give away it's presence. Try running some of your before and after images through aperisolve or the cyberchef entropy analysis tool and see how the analysis changes.

Modern forensic analysis tools would be able to detect the high entropy encrypted data within the host file fairly easily. Additionally, the process of embedding the unencrypted session key, salt, file size, and then the encrypted data as a struct like you are would increase the detection of embedded data.

Half the battle is making sure the hidden data cannot be detected and the second is that the data cannot be read if detected. A more algorithmic approach to the embedding and extraction which uses properties of the host file to determine the relative locations of the session key, salt, file size, and data would likely better hide the presence of the embedded/encrypted data.

I recently made a novel implementation of, "An Image Steganography Algorithm using LSB Replacement through XOR Substitution (DOI:10.1109/ICOIACT46704.2019.8938486)" which you can find here: https://github.com/JustinPack/XOR_LSB_Stego

While my approach is a simple one lacking any inherent encryption, it could easily be added. I think you will find the paper a highly interesting read and it is also in my project.

Cheers and great work nonetheless.
