Whatever the format, let’s hope it doesn’t end up having the extension .map

Wow, this is awesome, thanks!

You should spread that idea around more, it’s pretty ingenious. I’d add first converting to B&W if possible.

This is a great point. Image watermarking steganography is nearly impossible to defeat unless you can obtain multiple copies of the ‘same’ file from multiple users to look for differences. It could be a change of a single 5-15 pixels from one rgb code off.

rgb(255, 251, 0)

to

rgb(255, 252, 0)

Which would be imperceptable to the human eye. Depending on the number of users it may need to change more or less pixels.

There is a ton of work in this field and its very interesting, for anyone considering majoring in computer science / information security.

Another ‘neat’ technology everyone should know about is machine identification codes, or, the tiny secret tracking dots that color printers print on every page to identify the specific make, model, and serial number (I think?) of the printer the page was printed from. I don’t believe B&W printers have tracking dots, which were originally used to track creators of counterfeit currency. EFF has a page of color printers which do not include tracking dots on printed pages. This includes color LaserJets along with InkJets, although I would not be surprised if there was a similar tracking feature in place now or in the future “for safety and privacy reasons,” but none that I am aware of.

It’s new as of about 1-2 months ago.

Unfortunately that wouldn’t work as this is information inside the PDF itself so it has nothing to do with the file hash (although that is one way to track.)

Now that this is known, It’s not enough to remove metadata from the PDF itself. Each image inside a PDF, for example, can contain metadata. I say this because they’re apparently starting a game of whack-a-mole because this won’t stop here.

There are multiple ways of removing ALL metadata from a PDF, here are most of them.

It will be slow-ish and probably make the file larger, but if you’re sharing a PDF that only you are supposed to have access to, it’s worth it. MAT or exiftool should work.

Edit: as spoken about in another comment thread here, there is also pdf/image steganography as a technique they can use.

That’s a nice thought.

Then you suddenly realize no one knows up from down or down from up. Society would shift on such a massive scale people would probably just stick their smartphones in a drawer and only use them to message people they already know personally and check them a few times a day like an answering machine.

Then suddenly you realize you haven’t heard about Ukraine, Russia, Israel or Palestine in months. It’s November 28th and you heard someone mention a ‘new president’ but you didn’t even vote. Shit, you forgot to vote. There were no social media or news websites reminding you about the election and you didn’t have it on your new wall calendar yet! Ah that’s what all those “Vote Now!!!” yard signs were about, fuck…

It’s a nice thought, but the internet is powered by ads. (Almost?) Every subscription-supported website is also ad-supported. The internet would basically go under. AFAIK all the Lemmy apps have ads too. It’d be a nice change to get back to get a force shove back to the early-mid 90’s. Maybe we’d do things differently. People would certainly be outside talking to each other a lot more.

I think it’s not humiliating, but if you know someone, you should have some idea what they like/their interests are. Getting a small gift that fits them shows that you spent at least a small amount of time and thoughtfulness picking out or making the gift. If you don’t know the person, sure, cash/gift card.

Although I think it’s becoming less common to have the space or ‘the time’ (but we could prob all spend 30 mins less each day doing nothing on our phones) so giving physical actual gifts are becoming less common, and also due to the economy the idea of ‘mandatory days of gift giving’ is a bit off-putting. People love getting personalized gifts from people who create things, but far less people today ‘have time’ to learn a hobby where they create things in physical space.

Less “Fuck you here is $10” and more “Here is $10 as agreed upon by the social contract unwritten by the masses who came before us, I didn’t have any clue what you might like or want and didn’t think to ask.”

Some people gladly prefer cash/card. I am one of those people. We will make that known well ahead of time.

Since its servhold, you may be able to remove the offending content (for a short time, anything public-facing) and then contact reg.xyz to get it unsuspended. You’re right though that’s not very good customer service.

On a related note, it’s possible a misconfiguration allowed some of the contents or index to be shown publicly and it got caught in a search engine and was taken down in an automated DMCA sweep. I believe .xyz is an American registrar so have to respond to DMCA but could be wrong on that. I like to stay with any .TLD that archive uses… md, ph, etc.

Njalla just buys domains from major registrars on your behalf and owns them on your behalf. Godaddy, Tucows, etc. It was the owner of the entire .xyz space (gen.xyz) who shut your domain down. Njalla is just passing along the info. Porkbun will do the same.

Who was that guy that discovered something very important in physics, and he said the elves told him about it? The elves that were in the massive holes/caves he would dig in his back property, as his outlet. I forget how large his friends said the tunnels were, but he clearly spent a lot of time digging tunnels.

Edit: Seymour Cray, of the Cray supercomputer. AKA The Father of Supercomputing.

John Rollwagen, a colleague for many years, tells the story of a French scientist who visited Cray’s home in Chippewa Falls. Asked what were the secrets of his success, Cray said “Well, we have elves here, and they help me”. Cray subsequently showed his visitor a tunnel he had built under his house, explaining that when he reached an impasse in his computer design, he would retire to the tunnel to dig. “While I’m digging in the tunnel, the elves will often come to me with solutions to my problem”, he said.

Cray has been called solitary, uncommunicative, secretive, and difficult to get on with. Frank Sumner, Professor of Computer Engineering at the University of Manchester, met Cray on several occasions and refutes suggestions that he was a prickly character: “He was a very friendly man, and perhaps the greatest all-round computer scientist ever”, says Sumner.

If you buy fresh tuna and the country of origin date code is MM/DD/YY while you’re DD/MM/YY or YY/DD/MM or YY/MM/DD you could end up with year-old fish or worse. So yeah.

And no, it won’t always be something easily detectable by look and smell like fish.

Because of the other writing on the package, I’m wondering if because its sold on the international market and dates would get very confusing and possibly harmful.

Friendly reminder that Bluetooth has a larger network stack than Wi-Fi. Much more code, much larger available attack base. There have been many numerous Bluetooth vulnerabilities that allow remote code execution or theft of files.

This is truly becoming a surveillance state, in no way that can be debated. That want to be able to access everyone’s innermost thoughts (texts, notes, recordings, calendars, contacts, photos, you get it) without any chance of someone being able to protect against it.

Reminder that Google was the 2nd or 3rd company to commit to NSA’s PRISM program of feeding American’s data for future analysis.
