May I ask a hypothetical? If you were stopped at a border crossing and asked to unlock your drive for inspection, would you do so?

If you were stopped at a border crossing and asked to unlock your drive for inspection, would you do so? It's not necessary to cross a border anymore with anything "interesting" on your laptop. Just push everything of value to the cloud before crossing. Carry a USB drive with an OS on it. Format your laptop before crossing. Let them have fun "inspecting". Oh, and I'd advise doing something like dd if=/dev/zero of=/de…

The fly in that ointment is that govts tend to have these deniable 'deals' with these major cloud providers. So make sure whatever you push is encrypted well.

Usually you don't have any right to enter a country, unless you're a citizen.

So they can make unlocking any of your accounts a prerequisite for entering.

FDE is not supposed to be an anti-stealing mechanism anyway. Besides any potential thief wont even know whether you're running FDE or not on the laptop they steal, or whether it would be bricked or not. They can always sell it for its parts (screen, etc) anyway.

It actually is a mechanism to reduce impact of theft. Someone with access to your computing hardware might modify it to subvert the system, read keystrokes, decrypt drive, leak it, and so on. This can be as simple as Customs installing something as you leave the country during an "inspection" then reading keys right off when you come back. Not saying it happens so much as a concern we had during a brainstorm. Or some…

>It actually is a mechanism to reduce impact of theft.

Sure, but that's different from anti-stealing (and I mean stealing the machine of course, not the data).

On the other hand, it's quite nice to be on Hacker News where someone will post the definition :) ... now I know what that phrase means when I hear it in another context.

Nah, it's just the standard HN-ian modus operandi of misusing Latin phrases like a priori which doesn't actually mean "prior" or "prior knowledge" despite the incessant use here on this site. How else would I attempt to appear superior? :^)

If f is a function with the domain of thoughts and the codomain of the words used, f is almost never injective.

You can't always know the thoughts based solely on the words. There's almost never a one-to-one mapping. You can't always read minds.

Think about it like this: I understand that it might be perceived by some English speakers as "sophistication" (more on that later), but for a lot of others who speak other languages, there is absolutely no pretense of sophistication in using latin expressions for this is both how we have always talked and what we picked up along the way in life.

Expressions such as "a priori", "grosso modo", "primo/secundo/tertio/quarto", "sine qua non", "ad nauseam", "a fortiori", "a contrario", "status quo", "de facto/de jure", are very common in colloquial French.

Others, for example: "quod erat demonstrandum", "reductio ad absurdum", and some of the aforementioned mostly were picked up inmaths classes/books.

I learned most of this stuff as a child because people just talked like that around me. Do I have to appologize because someone thinks I'm doing it to appear superior? That's similar to some people who think someone is arrogant just because he's good looking. Doesn't this feeling tell them more about themselves than about the hypothetical arrogance/sophistication attempt?

Think of it another way: If I work in the sun and get a tan, why on earth would you assume that my tan is pretentious? Seems silly to connect the two, right? But they were connected in the past: the expression blue blood, after all, that is used to describe nobility came from the fact they were so pale their veins we apparent, contrary to the peasants who had to work in the sun and were tanned..

What used to indicate "low-birth" now has become attractive. We're funny that way.

To get back to what I said, this is not unique to English speaking people. I was raised with two languages home + one street language + one school language. Other children from poor families (one street language + one school language) preceived this as a sophistication attempt because they perceived me as someone coming from means. I wasn't. They associated speaking that language with wealth; I didn't. It didn't even cross my mind.

Then again, it's not even about wealth: they didn't mind someone like them (farmer) having money.. but they loathed people they considered "fancy" (for them, educated meant fancy).

Some people here have this stereotype (the correlation is that they're mostly people from poor neighborhoods) because they don't understand basic logic: "A implies B" doesn't mean "B implies A". They think "People from wealthy fancy families speak French", so they go the other way around and say "People who speak French come from wealthy fancy families".

But then again, it's not about latin phrases, wealth, or french, for some people in France would consider someone speaking in English as attempting to appear superior. And it's not even about France for some people in Egypt think people who speak English try to seem superior. How 'bout that! You wouldn't consider English fancy, would you?. But a lot of people around the world do.

What's the conclusion? The conclusion is that this isn't about the other, it's about us and our thought processes, our insecurities and assumptions.

The conclusion is that if you perceive what someone says to be an attempt to be sophisticated, maybe you can start with an assumption check: can you for a fact read minds? Does your assumption tell you something about yourself more than it does about the other? It does.

I'm not being judgemental, I just find the way we think fascinating. I spend a lot of time trying do destroy my own arguments and prove myself to know nothing. I also play pool against myself, keep score, and laugh at myself when I botch a shot.

I don't. I don't even have an account password for my windows machine. I want whoever has my laptop to have access to my PC so he can use it - in the hope that I will gather enough information about him and I will track him down to recover my laptop.

If the pc is fully encrypted, they'll have to erase the HDD and the programs I installed will be gone along with my chances of ever recovering it. On the other hand, I adopted the same behavior for my linux laptop and I'm not sure it's wise, the chances of someone continuing to use it are slim at best.

I see some merit in your argument. I have a little more take on this.

Leave a password free account and have a password based account also. It allows the stealer to use computer without hindrance and also protects your data from casual thieves at workplace.

I originally had the encryption turned on for my macbook I purchased back in 2015. It ran fast enough that I did not mind it.

The thing that ultimately convinced me not to use it was a seasoned apple store employee. He said if something goes wrong and you have it turned on, we cannot recover your data for you.

I am more risk averse, so I went with not encrypting the entire drive.

If I did need some encryption on OSX, I would probably go with creating a directory and using the Disk Utility that is built into OSX to just encrypt that directory.

That sounds like an annoyance, not encryption to me.

It reminds me of how I set a boot password in the BIOS on my HP laptop. I now have forgot the admin password in order to remove that "feature". I have no idea how I can fix it. The laptop is bricked. I can't install Linux on it because it is set not to boot from USB or CD/ROM

I had the same issue with a second hand HP laptop. However, I could still log in as administrator on the Windows install, enabling me to dump the flash memory used to store the BIOS firmware and configuration, which included the password hash. Some reverse engineering later, and I was able to brute force the hash successfully. So that could be an option if the password is not stored in battery-backed memory, and you have a bit of time on your hands to get stuck into the BIOS internals.

For others: Sine qua non is an indispensable and essential action, condition, or ingredient. It was originally a Latin legal term for "[a condition] without which it could not be", or "but for..." or "without which [there is] nothing".

If a phrase is so foreign that you feel the need to italicize it, don't use it.

I contend that 'sine qua non' was the mot juste in that situation.
