Geeze. This could result in some catastrophic errors. An order for 900 servers instead of 200. $7M loss instead of $1M in your quarterly earnings. Pricing your product at $3 instead of $8. Makes you realize you need some redundancy and double-checks for important communications.

Earlier quoted context omitted.

If you're scanning a long document to a PDF, compression makes a lot of sense. It's the difference between being able to email the PDF as an attachment and having to find a place to put the file online.

It is amazing the things people expect to be emailed. Can you email me the MRI scan? It's over 1500 images. Can you email it?

It's amazing to me the engineers who refuse to update their worldviews about normal people's mental models for "sending data" that still get amazed by this.

The size of the files or the number of them are totally irrelevant.

That's quite possible. http://www.cs.columbia.edu/CAVE/projects/face_replace/ I can imagine someone turning the technique into a novel form of image compression, maybe for surveillance databases or something.

Think how someone could falsify your entire life...

Then realize you shouldn't define your life based on some digital records.

Emailing the file or emailing a link to the file is just as useful. As long as you have an encrypted document sharing capability you should be able to say sure to just about anything.

PS: Granted that's assuming fast networks. For 80+ Gig VM's sending a removable drive is often faster.

Cached copy, which is missing the updated content: http://webcache.googleusercontent.com/search?q=cache%3Awww.d...

Thanks. As of now, the cache seems to contain the update. It begins with:

Edit: In the last section, it is now sketched what the reasons for the issue may be, on the basis of several emails I got.

I don't define my life based on some digital records. But law enforcement (or the executive branch of the US Federal Government, including the NSA) does. And therein lies the problem.

Someone will be convicted (perhaps even without the intervention of a court) based on unimpeachable but falsified digital records.

Especially considering that faxes, copies, and scans of documents are legally the same as the originals, at least for ordinary business purposes.
