My understanding is the 5GHz radar is considered pretty stupid and shouldn't have been deployed due to the interference concerns. Most deployments are on other frequencies. The 5GHz deployments are limited and generally in the US. I don't remember the details, but I remember when this was a thing when I was working on WiFi standards. I may have remembered it completely incorrectly.
Honestly, until they get the issues of liability sorted out, the self driving car is a complete non-starter.. precisely because of crap like this.
This is for governments to make laws just as they have for vaccines. It's the same deal. Over a population it will save many lives. In some specific instances it make kill someone. The government gets to make laws that protect the vendors from the specific cases so the general case can be realized,
Because 30 years after I used if in my O-level exams (UK exams) it's still working fine, it does what's required and it's not huge like a TI. HPs are good too but I couldn't afford one when I was at school and after 30+ years with a Casio, I'm not about to change.
Yes. I know the rules. I was a member of the 802.11 and 802.16 working groups and Bluetooth sig that developed these unlicensed band protocols and I've developed WiFi, WiMax and Bluetooth products. Having a protocol that bangs out a base station frame structure like LTE which splats on the band and has no backoff for other users of the band isn't part 15 compliant without being at a power that isn't useful for high speed data communications.
So you're saying it's an ITU/3GPP/esqu spec for a protocol and I'm not allowed to deploy it in an unlicensed band, but carriers who already have exclusive access to licensed spectrum are?
Could you explain how the LTE frame structure is compatible with part 15? I don't quite see it.
It's a refrigeration problem. You need to get stuff very cold to dampen down the noise (other things entangling with your qbits).
Making things cold takes energy. The lower the entropy in the qbits, the higher the energy that you blow in the refrigeration. Overall entropy will increase. So you might be able to equate the energy in the heat of serial computation of an O(2^n) problem to the energy spent cooling a circuit cold enough to solve an O(2^n) problem in parallel with magic quantum behaviors. Unfortunately in the parallel case you have to blow that energy all at the same time. If the serial case looks like it would need enough energy to boil all the oceans (about O(2^128)) then the parallel case might boil them all at once. You might want to get inland.
Say goodbye to asymmetric encryption. Symmetric like AES can still survive quantum attacks with a doubling of key length. But all the current asymmetric algorithms are in peril once quantum computers exist.
Say hello to quantum encryption to replace some uses of asymmetric algorithms (which are often only used to exchange keys for symmetric algorithms).
The real danger is to public-private key signature algorithms (such as those used to sign certificates). At some point these may need to change to use proof-of-work (e.g., bitcoin) style authentication or other cost prohibitive measures...
No, there are quantum secure public key algorithms. They are around 2X less efficient on key size than ECC. So it's not a huge problem.

The selling point of things like lattice crypto (e.g. NTRU) is that it is quantum attack secure.
But don't worry. They aren't going to build a working quantum computer that can factor large numbers or solve the DLP over elliptic curves. They can't make things that cold.
that this is an attempt to kill wifi and have LTE take over so you must use carrier moderated sessions for all you communications along with crap crypto.
What I hate about the Big Bang Theory is the temporal asymmetry of a low entropy point just choosing to pop into existence with no understood process for getting that low entropy situation out of an earlier higher entropy situation. Either it did, or it didn't. Either way, it's asymmetric.
Yes, the IT Crowd has even cheaper stereotypes: women can't cope with computers; management does nothing; IT workers are either slovenly men with poor social skills or OCD men with poor social skills.
It's about a livery company whose legally questionable practices and claims have drivers that are picking up hailed fares.
That's the black cab drivers' side of the story. The reality is that they are operating as a minicab business taking passengers on pre-arranged rides, which is perfectly legal, only they have replaced a phone call with a smartphone app / webpage. As long as Uber drivers are not picking up random people they spot trying to hail a cab on the side of the road, they are not infringing on the black cab legal monopoly.
Of course it look identical from the outside. No one sees the person using their app, but they see them standing outside waving at a car which them picks them up.

How many moons do you need to make an effective cluster?

Isn't is the murder weapon that can be left somewhere and the home address that is pretty permanently fixed in one place?
Accessing Github is crime?

What's an asymmetric hash? Do you mean a signature?

How the hell do I deploy this in my home without breaking wifi and without issuing my own SIM?
> it'll provide additional capacity boost that improves the UX for all users
No. For the ones who aren't having their WiFi shat upon. This is pure evil.

Measurement, collapse and entanglement are the same thing : https://www.youtube.com/watch?...
So we can try and factor 0,1,2 and 3?

All men? Are we all toxic brogrammers or are you willing to accept that some of them know how to communicate effectively?
Another behavior that would confound the inference that is being asserted.
Hmm. Modded down for pointing out basic statistics. Perhaps people want reality to line up with their received wisdom.
