What end-to-end encryption does give you is confidentiality against 3rd parties and authenticity of the sender and these are both critical to have.
Sorry, to be more precise, encryption does NOT provide you with authenticity of the message at all. Signing your messages does and there is no requirement to encrypt for signing a message. I sign all my emails digitally and anybody can still read them. I sometimes encrypt also.
Encryption is done with the public key of the recipient so it doesn't prove authenticity since anybody has access to the public key. Signing is done with the private key of the sender so it does prove authenticity.
Sorry but to be fair, some "private" industry engineers had warned of what might happen prior to the launch but NASA pressured them to give the go ahead anyway, even excluding those "private" industry engineers from the talks regarding the go/no-go decision..
There is no reason those cards will not last 10x longer than a GPU in the average PC sold to someone in a dusty house.
Did you ever see those tiny screws on the card fan cover? They are there to taken off to clean the cooling hardware once in a while. It gets pretty packed with dust after a while indeed. After a cleanup, the cards are as good as new.
Also, I must have been thinking WWVB which can maintain an accuracy of 100 microsecond if you program in the delay (distance from the tower). If you couple it with an enterprise grade ntp server, you can get a better accuracy than 100 microsecond as stated below.
The frequency uncertainty of the WWVB transmitted signal is less than one part in 1xE12. If the path delay is removed, WWVB can provide UTC with an uncertainty of less than 100 microsecond. The variations in path delay are minor compared to those of WWV and WWVH. When proper receiving and averaging techniques are used, the uncertainty of the received signal should be nearly as small as the uncertainty of the transmitted signal.
I still don't see how a ntpd server syncing over WiFi could be more precise than a stratum 0 server syncing with WWV. All you need to do is tell the stratum 0 server how far it is from the tower. Pretty damn accurate IMHO.
From OP:
It's only accurate to a millisecond within a 300km radius of the transmitter. NTP over WiFi is capable of much higher accuracy. GPS much more than that.
I really do not see how your ntpd server is going to keep "better than a millisecond" precision over WiFi and I ran a few use cases;-)
This sounds very counter-intuitive. Not to say that you are wrong although. Who knows with the fancy ntpd algorithm? But then again, it should help WWV just as well as a WiFi connected device. Are you talking about a dedicated WiFi connection just for time syncing?
Anyway, please provide some links if you have time. That might help me educate myself a bit.
What you, well, they suggested seems such a simple solution. Beside lack of will, the other thing that I would look into is deployment costs. It might come out cheaper than the bomb solution used in Sweden anyway.
The Swedish case was a very special use case that doesn't necessarily apply at large. The bomb was used as a last resort solution.
I wonder who got the idea that it was a nice approach at large...
From TFA:
To make matters worse, the blaze is in a target-practice area which contains undetonated shells. This has made it difficult for firefighters to get safe access to the fire on the ground, and other options have so far proved fruitless.
At noon on Wednesday the Armed Forces dispatched two Jas 39 Gripen fighter jets to drop a bomb on the flames as a last resort, with the hope that the pressure from the blast would help contain the blaze.
The difference here is that if he had had a breathable air supply, this is Star Trek after all, he might have still survived. With a bomb, much less likely.
That's not to say that this is a particularly good idea. A better idea would be to get better imaging technology involved and catch the fires when they're still small enough that a few dozen bucket loads of fire retardant are sufficient to do the job.
I like your suggestion!
On the other hand:
As far as animals go, that's pretty much a non-issue. The ones that can get out, get out and the ones that don't don't. Having animals hanging out there just at the edge of the fire would be highly unusual.
Don't take for granted that animals necessarily take the same approach as humans in case of a fire. Some take refuge in the very fire area: https://en.wikipedia.org/wiki/...
Exactly, imagine being caught in a forest fire somewhere without anybody's knowledge and that you have managed to find a sweet spot to stay alive and then the bombs come at you. Now you really get the battlefield experience!
Seriously, wild forest fire areas are hard to clear of human presence in advance due to their unpredictable nature. One might also think of animal casualties.
Yes they are smart, how long before they figure out how to fool the system and submit false cigarette butts or fake false small pieces of rubbish or go get them straight from the factory or the from local trash drop off or from the ashtrays?
In the city where I live, most businesses lock their outdoor ashtrays so the homeless people don't come pick through them. Watch those crows! They will figure out a way to unlock them! Jackpot!

Goof for you but I won't make that call before hearing Bennett Haselton opinion on the matter.

Reading comprehension problem maybe?
Re-read what I wrote and re-read the linked page entirely and make sure that you understand everything.
Thank you,

Hahaha, I first misread: "Google Is Poised To Open Its First Amendment Retail Store".

Sure, I could have used "stratum 0 device".

They will suspect you of drug trafficking. Coke is often hidden in banana shipments so they will think that every sticker means a kilo.
I am a security researcher and I would like to know if there is a howto or a proof of concept available somewhere?
Please provide links if you have them. This sounds like a really serious threat that I definitely need to look into.
Thanks in advance! :)
I don't understand your point!
Get them a hand held shower massage if you want them out of their quicker.
Please explain...
Also, where are their quicker located, what is it?
Thanks,
I like your reply. Maybe lack of will?
