When your full time job is designing RNGs, Reading articles on RNGs can be a little painful.
The term "TRNG" (True Random Number Generator) is a poorly defined thing. I think people think it means 'ideal non deterministic' but it's never used in that context and in this case we certainly don't have such a thing.
The thing they designed is a an "entropy source". It produces partially entropic nondeterministic data.
The chain of events in an RNG is..
Entropy source --> Online Test --> Entropy Extractor --> (If needed for performance) A CS-PRNG. (crypographically secure pseudo random number generator).
Entropy source : Makes partially entropic data. It doesn't matter what kind of source it is, whether quantum, lava lamp, circuit or whatever else, you never get perfect entropy from a physical process. The entropy extractor distills this kind of data into a smaller amount of data that is close to full entropy. 'Close' is mathematically described in terms that matter in cryptography.
Online Test: Continuously checks the ES is working while it's running. -- Top tip - This is the hard bit in RNG design.
So unless they can build and online test an entropy extractor in carbon nanotubes, they don't have a solution but they do have an entropy source. I don't know if they have done this or not, because the link in TFA doesn't work, despite my corporate IEEE account. If they have, then well done. If not, it's interesting anyway, but not ready for application.
And yet, big Android manufacturers are going the Apple way on this one. First Samsung, now LG. It seems like customers don't really care.
I think it's more like customers will put up with quite a lot of crap in order to have an otherwise top end phone. Choosing devices that have these utility features seems to always be a compromise on some other vector, like the software or CPU or storage or screen or radio or something else. I am no exception with my iPhone 7+, but the headphone and adapter situation means my next phone will be an Android. I went from a long line of Android phones to the iPhone 6S+ just to see what it's like on the other side - it was fine until they pulled the headphone stunt.
This is central to my thesis that vendors can indeed differentiate themselves on features if they put their minds to it. There's lots of room for improvement.
Yes, but 'beg the question' is just a really bad translation of the original phrase. Let 'beg the question' have its new meaning, which makes linguistic sense, and come up with a new phrase for what is essentially circular logic.
However, it's not some obscure corner of the English language. It's taught in school, by English teachers, to children. They learn and remember these things that add the semantics to the words they hear and say. The various types of logical argument and logical fallacy are taught. These things were even taught in school in the crappy mining and steel-works shithole that I grew up in.
It's not hard. It's not inaccessible information. It's not like it doesn't get pointed out most times that people screw it up. This is because most people know how it works and it sounds very wrong to people when it's used wrongly. Just like conjugating wrong or engaging in Yoda speech. I'm happy that people like to boldly split infinitives. English accommodates that. It doesn't accommodate sentences of the form . It sounds ridiculous.
Nope. Lenovo had the closest with multiple sim support and replaceable batteries.
My iPhone 7+ has been bad enough that my next phone will be an android. The headphone thing was bad. Disabling my 3rd party headphone+charge adapter when I was travelling was the last straw.
If anyone does a phone into which I can pop a couple of 18650s, I'll buy it.
>Android manufacturers can't differentiate themselves on hardware.
Yes they can.
Sim slots : More is better. Externally accessible storage slot : Have one or more. Headphone Jack : I hear they are popular among people with ears. Replaceable batteries : This is a no brainer. Bigger battery options : This is also a no brainer. Hardware credentials : MFA sucks without it. USB-C with full support for the power delivery specification : It's past time. Physical isolation for dual personalities (like for access to a work network). Stock Android is a good feature too, why don't more do it?
My Lenovo has a removable battery and two sim sockets. I use it for travel in Asia. The UI is horribly messed up though. They are right to dump their stupid bloatware.
I do, The ambiguity in the second sentence was clear to me.
The built-up-ness did not remain at all, yet you said it did, You said it remained built up and left it to the reader to discern whether 'until today' means "It's still remaining built up today" or "the built-up-ness ceased today".
Don't they understand? Doing shit like this means we won't have DefCon in the U.S. any longer. Think of the hotels and all the revenue we'll be missing!!! Does Trump know about this?
This is becoming necessary. Similarly for more academic crypto conferences. They split their locations evenly between Europe, Asia and the US which in addition to sharing the travel pain, allows people to avoid countries that might try to prosecute them for being a security researcher. DefCon and BlackHat need to move about so they can be available to researcher that would otherwise be unable to travel there.
He may have helped to stop it, but it begs the question.. Did he have a hand in spreading it in the first place, or is this an unrelated charge?
It doesn't beg that question any more than it begs the question of why anyone who is a high profile security researcher would be stupid enough to travel to the US.
We're not even 2% in to the capability of 4G/LTE - why is thought even given to 5G?
I assume carriers are looking at LTE Advanced and the like because it can support a greater total speed per tower than LTE. With the same number of active users per tower, a greater total speed also means a higher speed per active user without having to acquire land for more towers.
Carriers are looking to fill your unlicensed spectrum with 5G crap and still charge you for the privilege, while borking 802.11 with exactly the right kind of interference to break the backoff algorithms..
Here in the US, I'm wondering what the big deal is for requiring an passport to move between sovereign countries over there?
I thought that was pretty much the norm for most of the world....?
It's a lot more than being able to move. Being an EU citizen allows you to live and work in any of the EU countries. If you're a British passport holder, you've lost a lot more than free movement.
In recent years, airports in Heathrow, Frankfurt, Barcelona, Belgium, Singapore, Tokyo and Penang all sucked for WiFi internet access. At least in Europe I can get a PAYG SIM that works Europe wide,
If you want to be useful, just install free wifi repeaters (starting from the goddamn airports, please), like any other civilized city in Asia do.
Like in Singapore where to use the Wifi you are required use the internet access you don't have to log on and register at a web site, then click the link in the email they send. Genius!
Has there ever been a city installed WiFi that didn't completely fail to work? I've tried a few. Not even airports can get it right. When a city, town, borough or municipality set out to provide public WiFi, they go on to demonstrate that they don't understand how to deploy RF services and that they don't understand how to maintain an internet service.

>a subset of artificial intelligence (AI) that mimics how the human brain works.
We already have humans for that. How about doing things humans cannot do?
Yes, but 'beg the question' is just a really bad translation of the original phrase. Let 'beg the question' have its new meaning, which makes linguistic sense, and come up with a new phrase for what is essentially circular logic.

If there are k editors and n journals, how many ways can you allocate those k editors between the n journals?

But you still don't understand the mathematics.

Or even being pernickety.

Disambiguation for the Nation! Now!
The 3 WannaCry addresses used that held the Bitcoin from this exploit have been drained
They have remained built up on these addresses until today.
So which is it? They've been drained or they remain built up?

No question was begged. It raises the question. Begging the question is something else entirely. https://en.wikipedia.org/wiki/...
4G/LTE can support 1Gbps.
Per tower, right?
We're not even 2% in to the capability of 4G/LTE - why is thought even given to 5G?

Well that nails her down.
Ms. Wang, China.
I could tell you about what it's like on corporate jets, but that might not make you feel better about your situation in Suvarnabhumi.

San Francisco, Chicago, Heathrow and Charles De Gaul are in my near future. In this instance, it's not a work trip so I may not care about WiFi.
I have no memory of Schipol's WiFi sucking, so it must be fine. I wish your packets swift passage.
Sorry to break it to you, but pedestrians always have the right of way
No they don't.
