I never said to leave him alone or that he's a hero or that he's the only one driving humanity forward or that he's perfect. Sometimes he's an asshole. Sometimes he's an idiot. He's flawed like every human.

Your childish cult-like "spaceman bad" programming and angry projection of your daddy issues says more about you than anyone.

Ashlee Vance's biography of Musk (from a few years ago) had a fun similar story. Someone inside Tesla wrote a letter, I believe complaining about product defects, which was printed by a media outlet. Figuring that the leaker printed the letter at Tesla offices (i.e. likely didn't have a printer at home), Musk re-typed the letter in Word, found out exactly how many kilobytes a Word file with that exact text would be,…

The most impressive/unbelievable part of this story is that 2 Word files, created separately, ended up with the same exact file size. I'd assume with all of the Metadata they cram in that this would be unlikely.

Parallel construction.

He searched the printer logs . Presumably when Word sends stuff to the printer, it doesn't bother with all the extraneous garbage it puts in files. Printer communication hasn't changed much in decades.

Still. He’d have to have the same normal.dot, make the same space/tab choices, same fonts, etc. And in a large company, how many ~1 page letters get printed? What are the odds that there is only a single match in the entire company? I take this story similar to the binary coded space story: more likely to be apocryphal and promoted to deter future leakers than true stories about catching them in the past.

You could filter on time and size and then get a subset of likely candidates and whittle it down to the expected people.

Honestly speaking, the story sounds somewhat believable to me. They likely misidentified the leaker with that silly analysis and fired them on the spot, would be just the usual modus operandi of musk.

Two different leaks. One was a printed word file. One was a double-space-encoded email.

Years ago, I worked at a place that attempted this. They were so giddy about it. There wasn’t even a known leak, or, arguably, anything particularly worth leaking. They were just tickled by the idea that they could gotcha anyone who tried to leak something. Then, as now, it strikes me as little more than sad and paranoid Tom Clancy cosplay. I’d like to say I’ve moved on to a place with a culture of trust and faithful…

>it doesn’t seem like anyone really trusts anyone anywhere anymore No offense intended, but have you considered that maybe you're just surrounded by bad people? I have a reasonable amount of trust and faith in the other people that I work with. If I needed someone to pick me up in the middle of the night from the hospital, I'd trust my coworkers as much as I would trust my wife or friends. My company is hardly some "…

Oh, sure. Me too. And then someone I trusted utterly fucked me over. Like six figure fucked me over.

So consider that your trust, your opinion, is based on the past, and you have no actual idea what will happen in the future, or tomorrow even.

1) It's been more than once that we've seen hackers completely wipe people's digital lives? I mean, how problematic will logging in to many of these services be if Google decides to lock your account? 2) As an American example, ask Trump, he really doesn't want to release that information for one reason or another. Simply put trying to figure out other peoples security and sensitivity sensibilities is not something y…

There are still much more convenient and technically superior methods than using physical paper copies if that is your concern. > ask Trump, he really doesn't want to release that information for one reason or another.

Technically superior is a very biased argument... A safe with a key is a very well established security mechanism with a pretty easily traceable chain of custody. Someone has to physically be at the location of the files to get the files.

Any digital record has a huge number of failure modes. For security you'll want to encrypt, when encrypted you'll now have another piece of data you need to secure and backup. You have to ensure the backup services are secure. If any of these become insecure how do you trace the insecure accesses? If it was accessed from overseas what do you do about it?

Criminal activity is common, but lets go with something that would be criminal in one country and not in another... This gets very messy with cloud services where some other government can request the information. With a safe you have to get the local government to sign off on a warrant.

If they actually did this, it's nice that they leaked their playbook. Advice for future leakers: 1. Ask your co-worker to forward you that email (because you "accidentally deleted it"), and diff to your copy, so you know if your employer is cosplaying as the CIA. 2. Retype everything before leaking or leak crappy photos of documents on your screen (or better yet, both). 3. Leak to a journalist and make them promise t…

Microfilm cameras if you want to cosplay as the CIA too

Mostly not necessary these days; everyone is already expected to have a portable supercomputer with a radio, passible quality camera, microphone, and shitty text input capabilities in their pocket.

Tyrions plot has a flaw in that it’s three versions of the same story. If two or three betray him, he won’t know and he’ll reveal to the queen that something is afoot. He should have used different stories.

He did use different stories, he tells each one something different.

But it's a version of the same story. If the queen hears that he's planning to marry Marcella off to Dorne and Theon, she'll know that something's up.

It’s called whitespace watermarking and seems to be one of those ideas that keeps getting re-invented. It’s used a lot, particularly in HTML where the rendering hides the identifying spaces. It can help you figure out if someone is scrapping your content.

Margaret Thatcher did this in the 80’s to help identify who was leaking cabinet documents to the press. I recall a story about Jobs tracking down leakers in his own executive suite by telling each of them a slightly different things in private. Not sure if it worked, but it can be a very effective deterrent.

Supposedly, even today, Apple will assign employees (especially new ones) fake projects in an effort to weed out leakers.
