Quantum sounds cool but what big potential application can people point to other than crypto? And if quantum resistant crypto is in place by the time serious quantum computing is in place, I assume the main application of quantum will be to read all stored, previously encrypted secrets out there.

I've been told quantum chemistry and physics simulation. For example drug discovery via simulation.

Branch prediction seems like a place where we want to compute multiple states.

I'll be honest, my knee-jerk reaction was "BlackBerry is still in business?". Anyone on HN own one or know of someone who does? I can't recall the last time I walked into a store who actually carried BB products on their shelves.

My spouse has a Blackberry and when it wears out he plans on replacing it with another Blackberry. Why? I dunno, something about it being Canadian and not from Apple.

I too have a Blackberry(Passport) for three years now, and if it breaks I'm planning on getting another one. The reason is simple: The OS is amazing and still ahead of all competitors in aspects that are important to me, it does everything I need well enough and I love the device's and screen's dimensions.

Honestly it made me lose all interest in any other phone.

More generally anything based on the discrete logarithm problem (so both rsa and ecc) are not quantum resistance. As explained to me by an actual maths guy the basic issue is that DLP is heavily biased across its key space. Shor’s algorithm leverages this by doing a Fourier transform that gets the incorrect values to cancel out. The quantum resistant algorithms work by creating an unbiased key space so there’s no abi…

I own a KeyOne, released last year with Android instead of BB's own OS. I love it, only downside is that I had to import it as it isn't available in my country ... I'd mainly used Samsung flagship phones before and got really tired of all the bloatware as well as typing on a touchscreen. (Can't believe more people are questioning touchscreen typing on phones, I think it's horrible and I don't have the largest set of…

People are seeing on touchscreen phones, which is faster than typing. I can't believe you're surprised people aren't using BlackBerries! Once paying for texts stopped being relevant teenage girls moved onto smartphones and that was the of BlackBerry.

Me too. I've had mine for ~4 years and it's going strong. Blackberry OS 10 is really nice, and I prefer it to Android and IOS. They seemed to 'get' what a mobile OS should be (i.e. a helper not something that takes over your life). Then again, it is frozen in time 4 years ago.

In the past I have had to install a root CA (for AWS or LE, I forget which), I have to use FTP to get my pictures off, but the trade-off is worth it in my book.

I always get an amazing amount of push-back (from astonishment to outright "you're wrong") from people who argue that no-one should ever want anything except what Apple and Google want to push. Well, some people do!
