If you had a language model (say, trained on existing comments from Reddit), you could encode the data in the comments in English, and make the abuse a little more subtle.

Wikipedia is full of hidden messages. A common pattern I have observed is the first letter of a sentence being used to string together a message. You can read more about this tactic here https://uncyclopedia.wikia.com/wiki/Subliminal_Messages

Also in 2010 there was a file storage system based on Bitly: https://nealpoole.com/blog/2010/12/bit-ly-file-storage-cleve... Super clever idea, except for the part where Bitly now sprinkles links with affiliate codes to make $$$

RedditStorage reminds me of a couple business models we tried out that tanked..

The first was a new business where we would go to trade shows, conventions, hell even fast food places, and just collect as many free beverages, condiments, napkins et cetera as possible. Then we'd sell them online.

The other one didn't do much better. We'd go to a Lowes Tool Rental, and just rent a bunch of tools and then re-rent them out of our truck in the parking lot. They had to have them back an hour before Lowes closed for the night.

Our current business model is, we go to bars and hit on people, and if we get their phone numbers, we add it to a subscription service where other people can have access to it.

Honestly, I feel we're no more in the wrong than RedditStorage is.. /s

There should be a contest: Who can find the most implausible data storage medium? (Rated according to various criteria such as ingenuity, reliability, max. data read/write rates, latency, storage size, costs…)

Is this actually proven? Pi is irrational, but is it proven to be random (or normal)?

Also, assuming that it is, if 'start as position X and read Y bits from pi' produced an illegal image (top secret document, abuse images, etc), what would be the legality of trading such information?

That just segfaulted my brain. Everything we may ever write in the future is already there, you just need the address.

While I'm not sure every number is in pi (see my other comment to grandparent), there is a similar really weird feeling I get when I consider all digital data is really just numbers. That means there is a number, that when turned into a .avi (or format of your choice), shows anything you can imagine. Imagine yourself talking with Plato. There is a number that produces a 1080p video of you doing just that. Actually, there are a lot of numbers that do that, as every little difference in the setting would be a different number.

There is a number that produces a high def photo of when you married your high school sweetheart, even if you never actually married her. There is one of you being awarded the Nobel prize. If there is a proof that P = NP, or that it doesn't, or even a proof that it can't be proven either way, then there is a number that would be the PDF version of that document.

A stenographed image embedded in a Word document, printed and faxed to a document archive that scans and digitizes it, embeds the scan in a PDF, and emails it back to you.

Pretty sure this happens in Washington DC when bills need to be reviewed by various departments.

The original image is a picture of a worker's monitor displaying some error message that IT asked for.

I'm not joking either.

This is pretty much exactly how binary newsgroups got started. Not to be all "I thought of it first" but I had thought it would be funny to do something similar on Twitter.

Woah, that'd be a lot of tweets. Even reddit with its 10000 char limit per comment has loads of comment trains if you want to store a sizable amount of info that way. With twitters 140 char limit, that would be a huge amount of tweets. You'd probably run the risk of being identified as a spammer if you send that many tweets at once...

140 unicode characters. Which actually gives you quite a lot of space to work with.

Well, one, I'd love a more general solution where I could just say "generate a sentence with n bits of entropy" and my algorithm would spin out a sentence of the correct (arbitrary) length. (Hmm... Markov chains?) Or maybe add other mnemonic modifications, like rhymes. And two, I still need an algorithm to conjugate verbs and whatnot, though I suppose that part could just be left to the user. (You get n diceware word…

I think Markov chains would be a bad idea for the use case of passwords because some words always follow certain words.

Ah, true — I was thinking more along the lines of "part of speech" Markov chains, if that's even possible. (As in, just an endless stream of "article noun verb adjective noun adverb conjunction adjective noun verb adjective noun conjunction adjective etc." that could then be mad-libbed by diceware.)

Yeah minus the encryption (well that's not 100% true as you could post encrypted files and people do but it's less of a part of the "protocol" than it is in this example). The beauty of newsgroups is they are replicated to other NNTP servers. Distributed file stores fascinate me (I know this reddit protocol is not distributed or rather it's wholly owned by 1 entity even if the data is distributed across datacenters) and I'm very excited to see where things like IPFS [0], freenet [1], internet2 [2], etc turn out.

To get reliable and free storage, photo hosting is usually the easiest way. Flickr offers 1TB, picasa/g+ offers unlimited storage with some hidden quoats. Everything that allows lossless photos lets you store arbitrary data. Depending on how careful you wanna be you can store hundreds of GBs per account. Email attachments used to be a great way a while ago but nowadays using multiple gdrive/dropbox/onedrive accounts…

I've done similar with images for the fun of it. The simplest solution that I recall finding was to base64 the file/data, then turn to hex, then use those hex data to create pixels in RGB. I would line them up top-left to bottom-right.

Probably not the most efficient but easy and fast and the resulting images would look... interesting. For large files, the decoding would be difficult mostly just due to reading the image of so many pixels into memory. So, that's when I began fixing the image size to a smaller size and having multiple images that I would later convert to 60fps video. I could then use ffmpeg to convert images to frames and frames back to images.

I had no practical use for this but, was a fun project on a rainy afternoon.
