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

Wow, this is awesome, thanks!

Unless you know specifically what they’re adding or changing this wouldn’t work. If they have a hidden ‘barcode’ and you add another hidden ‘barcode’ or modify the image in a way to remove some or all of theirs, they’d still be able to read theirs.

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 10-15 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.

Good question. I believe “Print to PDF” isn’t actually “printing” it page by page as if it was a physical printer, but rather just saving the loaded PDF to a PDF file locally.
I’m not an expert in this field, but you can ask on StackExchange, or ask the author of MAT and exiftools, or do it yourself by making a PDF with a jpg file with your metadata, and then extract the image and let us know here - it would be useful information that I can’t find via search engines. I’m using a smartphone so I can’t do it, but if you do, note from the linked SE page is you won’t be able to extract the original file extension, so if you use your own .jpg with your own exif data, rename to .jpg when finished (I believe exif is handled differently based on file type).
There are multiple tools to add exif data to an image but the exiftool website has some good easy examples for our purpose.
exiftool -artist=“Phil Harvey” -copyright=“2011 Phil Harvey” YourFile.jpg
(do this as the first step before adding to the PDF)

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.
There are multiple ways of removing ALL metadata from a PDF, here are most I know of.
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.
- Comment on Ant smell 5 months ago:
Yes it’s a fact that obese people smell worse than fit people, so if it was a marathon runners convention and everyone actually bathed daily, I’m sure going without deodorant wouldn’t be an issue. Too much fucking might be an issue if the majority of the women aren’t on hormonal birth control.
But I think the issue with anime conventions isn’t lack of deodorant, it’s thinking a shower is something you take every 4-7 days, and ‘eww don’t clean your buttcrack that’s nasty!’
I may get flack from the twox crowd for this comment, but talking to my fiance was like talking to a guy when she got off hormonal birth control. Conversation is just… chill now.
That’s probably the next big “oops, we fucked up bad the last 50 years, but men’s birth control is hard!”

Take it or leave it but my advice (sometimes I take it sometimes I’m a hypocrite) but tomorrow never comes. Fuck next month. There is no reason for you to wait to eat less sugar. If it’s a matter of finances, get a head of romaine lettuce and some carrots and much away for a few days. Feel the sugar withdrawal as your body freaks out wondering what has changed and starts realigning those neurons. Use that wasted $30 of high sugar snacks and food as motivation to stop eating this poison. If it’s purely a waste issue, find the first homeless person you see and give them a big bag of high sugar food. Even if its frozen meals they’ll give them to their buddies and use the microwaves at a convenience store and eat like kings for day.
Honestly, a big part of this comment was me talking to myself, but not about sugar. But if it helps you, I’m happy.

I take testosterone which makes my sense of pheromone smell increase like crazy (not just sweat, I can go into a truck stop late at night and tell if someone was in there somewhere and peed and how hydrated they were, or if someone just had sex in the shower in there… or just an orgasm.)
Sometimes I’ll walk into our own house bathroom half an hour after my fiance left for work and get an overwhelming woah, she’s definitely on her period right now smell or conversely, “tonight’s gonna be a fun night” but the latter requires me not slacking off on dishes or forgetting to do something.
Our oldest started showering in the mornings before school, and its become a subconscious (I think, to him) game of who can get in the shower first, because I do not want to smell his… shower… my entire shower.
Humans are capable of absolutely incredible senses when they’re finely tuned. We have known about, as one example, estrogen-raising (== testosterone-lowering) chemicals being in plastics leechinf directly into our bodies and soil and water and food supplies for over 30 years now (BPA), and around 2010 they did a study that found some BPA-free plastics released more estrogen into the system than BPA did.
Plastics, and then leaded gasoline, and then PFASs shortly after (or before) that… well, when a molecule or series of molecules is found that greatly benefits civilization in some way, people will die. People will sit under oath in front of the supreme court swearing they had no idea how harmful their products were.
It’s very unfortunate, because the species are being modified in so many unforseen ways. Not just humans. Alex Jones got meme’d so hard for the chemicals are turning the fuckin’ frogs gay!
I’m not sure what I’m ranting about now. I’m just sad for our species and those species affected by us and unable to do anything about it. It’s never as simple as it’s ALL profits and follow the money! because we’ve been able to make so much progress as humans through the use of breakthrough technologies like PFASs and plastic. But, at what cost? Our current methodology is to let the major corporations sell these new breakthrough molecules far and wide, and then in 5 years or 5 decades we start to see mainstream scientific acceptance that “okay, it’s really bad, we have to do something about this”…
Sure, though, it did some good in the meantime.

- Comment on [Serious] Why do so many people seem to hate veganism? 5 months ago:
For me it’s the high-horse holier than thou attitude most of them seem to carry in online conversations. I know a fee vegans and they are mostly fine in person after the first few months of radicalization, but I imagine they just suppress it in person to maintain the acquaintanceship and then bitch in their vegan echo chambers about how “my co-worker who knows I’m vegan had the audacity to order a hamburger and eat it in front of me knowing I’m vegan, does he know he’s destroying the world with that Burger… AITA?”
If you’re looking for scientific answers, good luck they, Inrhjnjbmost people stop worrying about micromanaging people after a few years of academia.
- Comment on Anon is a person of interest 5 months ago:
They use a mixture of both depending on suspect and observed operational security measures. It’s much easier to leave a phone on at home whole you go meet up with your connection, and if you drive an older car and don’t take any WiFi enabled or Bluetooth-connected devices sports watches, hiking gear, satellite radio, etc) then a physical tracker can guarantee much better data.
I’m available for security consulting knowledge.

T-Mobile prepaid. Mint mobile is also very cheap, but I think there is one cheaper now.
- Comment on Why are SMS messages so expensive? 6 months ago:
85 per phone? did you get suckered into a contract+new “free” iPhone or something? I pay 40/mo for unlimited everything in the States but could be paying 25-30 if I wanted to switch providers.
SMS message costs are a scam, always have been. It takes like 1-2 seconds worth of talk time for the same amount of sending a text.
- Comment on I learned so much 6 months ago:
My 6th grade English teacher Mrs Cash was the hottest teacher in the school. She’d sit in a boys lap and then ask them to come to the board to answer a problem.
Later it came out publicly that much of the school administration and teachers, city council, and some of the religious leaders were involved in a swinger ring. Small towns get down.

- Comment on sleep paralysis 6 months ago:
try sleeping on your back
chronic sleep paralysis is the reason I tuck a thick blanket under me when I roll on my side, so I can’t turn to sleep on my back on accident.
The spinning wormhole at the foot of my bed was the last straw. No more ‘just ignore them and go back to sleep’ after that.

Literal torture. There’s a reason LSD proved to be an ineffective truth serum… What’s going on inside the head is far worse than what could possibly go on outside the head.
Always trip with someone with actual experience, kids. There are ways to escape a bad trip, so ask your trip-buddy how they plan to ease a trip that’s going south, and if they can’t tell you 5 things off the top of their head, they’re full of it. But the best way is to start small and ease into it. Once you’ve gauged the dose and purity, you can have a bigger trip next weekend.

Let’s refer to it as 2010, birth of Sir Citizens United, because if the large corporations want something to happen, or to not happen, they’re likely to get their way after after a year or two.

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.
