Actually it wasn't designed to do that, it was designed to be a charger + serial data connection, exactly like microUSB. Someone else on here helpfully linked to this article which I found interesting. (apologies to whoever originally linked it, the article stuck in my mind, not the poster). If you read the article it tears down a lightning to HDMI video adapter, and notes that it has an ARM processor in it, something that would be unneeded if the cable itself was capable of spitting out straight HDMI video.
TL;DR Lightning cables have that nifty 'can be plugged in either way' thing going for them, and are arguably more durable than microUSB, but at the end of the day they're two specs, and two connectors doing exactly the same thing, if you want to snag a video feed from either of them, you need to have a 'dongle' that can capture and process the data pins on the connector into a proper video signal.
And we just crossed the line from science to sex...
Tyrone, you know how much I love watching you work, but I've got my country's 500th anniversary to plan, my wedding to arrange, my wife to murder and Guilder to frame for it; I'm swamped.
Thanks for that, I found it separately also, and read a few of the papers referenced. I tend to agree that this madness is a bit overblown. Reducing the time by 15% is really impressive overall, but when our anticipated sieving times for a typical 2k-4k keysize are measured in months and years that isn't a huge difference.
Okay, here's the slides from a talk:

And a paper which is related:

Basically, from my first read, this is just a better sieve, a system which should find smooth numbers faster by choosing better starting points and using faster tests. I wouldn't call it a general break in RSA, and while it might certainly be a better sieve than GNFS, it's no silver bullet either. I can't imagine anyone breaking RSA numbers like this unless they're very well funded.
Yes, it's all computation. Once you have the databases, it's done. Unfortunately, GNFS sieve's are only applicable to a single pair of primes, so you can't reuse the data for other problems.
I'm surprised to see other people going in the direction I've been going for about 3 years now. Really. I thought I was quite alone in my path, LOL.
I need to read this paper still, but if it's taking the same path I did, then it's not a peachy as some think.
I'm only am amateur, so take this from the point of view as someone who kicks back with a beer and enjoys solving impossible computational problems.
I don't think it's that close to being broken... I think it'll take a huge computing effort (think multi-terabyte databases) to generate the tables across the PQ space required so that existing problems can be used to quickly find paths and intersections. At the beginning you're looking at only a VERY SMALL speedup from modern sieving, but once the tables get generated (years of effort) you'll eventually see faster and faster improvements. At least, that's with my algorithm, which I'm sure is far from perfect and only works on a certain set of primes right now. Which is about 20%. Which is far from optimal.
So yeah, progress. But I'm unconvinced that this will work for all primes.
I'm going to read the paper now... which I'm sure is far better than what I've been doing.
Not really... people all over the world buy cellphones and import them for a massive price hike all the time.
I really doubt that Canonical would advance a vaporware phone. They've got a huge interest in going mobile with Ubuntu Touch, and the hardware designs already exist. There's nothing new here other than a particular mix of existing tech and a contract manufacturer.
Going for a prestigious custom design to show off their software looks much better than the 50$ chinese knockoff that the carriers will likely fund.
Will the Ubuntu Edge be sustainable and/or hardware hackable?
While we will do our best to keep the hardware as open as possible, these are not the main focus of the project in its first generation. Hardware that’s capable of convergence is the priority.
What networks are supported?
The Ubuntu Edge is an unlocked device that works in all countries with GSM/3G/LTE network services. For GSM, which covers a lot of countries but not all operators, the Edge will support the 850, 900, 1800, 1900 and 2100 MHz frequencies. You can check support in your country here.
The Edge will support LTE standard frequencies and multi-band support for roaming. Yes, you can use the Edge on Verizon and Sprint.
So no locked bootloader, but you will likely have to live with binary blobs also (like 99% of phones out there).
All power corrupts, but we need electricity.
