Obama entered office in 2009 and put limitations on the forfeiture laws the year before he was to leave his second term? It sounds like he was really against it, huh?
Sure you can believe that if you don't understand politics or if you're a 2 yr old throwing a temper tantrum wanting all the world's problems fixed, NOW NOW NOW.
You focus a lot on the efficiency of natural gas, the fact that EVs are actually coal powered, and then proceed to conclude exactly what I said: Rising EVs will increase power demand which will not be coal powered. While I'd like to see people choose nuclear as well it will be a mixture between gas and green for political reasons which will make a huge dent in our carbon numbers.
Also you're getting different numbers than I am on the contribution of passenger vehicles, so I looked up another source and got different numbers again, so I'm going to drop that argument but would be happy to find a peer reviewed breakdown of CO2 emissions per transportation method.
Oh it gets better too. These guys idled all their gas out of their exhaust only to find they couldn't fill up at any pump. https://www.dallasnews.com/new...
To be clear are you talking the kind of forest fire that you didn't know was coming and could not be escaped by driving over 100 miles? If so, man you're screwed. No ICE car will save you there.
Also to be clear are you talking about outdriving a hurricane? Travelling at 0 km/h in a traffic jam won't help you. Also there's those facts that more people die during an evacuation than the hurricane itself. I mean the USA just got hit with an almost unprescedented storm and had a death toll of what... 60, after plowing through a city of 2.3 million and cruising through a state with 8% of the population of the entire USA? Shit man I'll take my chances with the storm even if I had an all American Ford F350.
But it's good that you're thinking of disaster scenarios now. It will stop you making stupid decisions when the disasters actually hit.
commuter cars are really a small part of our total carbon output.
Passenger transport accounts for over 20% of our CO2 output.
Electric vehicles that are charged from coal are not "green".
Electric vehicles are not "charged from coal". Coal is baseload and is running regardless of what is happening in the country. If the USA switches to electric cars it will put more strain on generation requiring the construction of new power plants. These are not powered by coal.
Electric cars don't work when the power goes out, ICE powered cars do.
Gas cars don't work when the gas goes out. During a disaster you can make your own electricity but you can't make your own gas. If you get really stuck you can use gas to make electricity making this complaint of yours probably the single dumbest thing I've ever heard said about electric cars.
Electric cars aren't practical for long trips, or for unplanned medium-length trips, ICE powered cars are.
Electric cars are fine for both, unless your long trip includes travelling so far for so long without break that range becomes a problem. But you won't get to that point because you'll have driven your car into a tree when your brain gives up long before that. If you do this in an ICE car you're an unnecessary risk and should have your licenses suspended.
Electrics cars are a rich man's toy, ICE powered cars are practical vehicles.
Except for the Tesla Model X and Model S nearly every other electric car costs less than the mean US new car sales price. That is before rebates you get in many states.
No amount of band-wagon nonsense is going to change these fundamental facts unless there's a fundamental breakthrough in technology to stockpile and transport electrons. So far, there there has been no such breakthrough. Mary Barra is just another beancounter in a long line of beancounters who has no understanding of the technology her company sells for a living. This too shall blow over.
Let me rearrange what you wrote. In your own words: "No amount of facts is going to change this technology, [RightwingNutjob] is just another who has no understanding of the technology"
Dammit I hope you were going to use an "I" in that paragraph. Guess square brackets will have to do to emphases just how braindead your comments are. You really are just another RightwingNutjob
Silly hobbies like driving vehicles or cooking pot roast with a pressure cooker?
Both of those hobbies kill almost no one. A rounding error in the number of deaths in the country. Especially the vehicle deaths. Those who drive them as hobbies are statistically among least likely to die compared to those who drive for work or those who commute.
The whole good guy with a gun theory is completely asinine, it just adds to the confusion, and rarely if ever has a good outcome.
If everyone had a gun so they could be the good guy I would probably go a movie premier, throw a smoke bomb in the room and then just fire my gun into the air and walk out. There would be more deaths than James Holmes achieved.
Maybe it's just that an airport is a convenient place to hide the equipment and the device is re-transmitting it's own location to get around the problems of having to decode and re-encode the GPS signals.
You don't need to decode and recode. Other than for the military GPS signals aren't complicated or encrypted. They are well described and open. Also there are freely available tools to create fake GPS signals. All you need to do is pump them through a transmitter, not even a very strong one.
You apply an arbitrary black and white label to something with various shades of grey.
Ask a teen tweeting their lives away on social media if you can watch them having sex in their bedroom. Expect them to say no, because privacy isn't a black and white matter. Ask a person who used their same password on their facebook page since primary school why they also have a concealed carry permit. Expect them to take a defensive stance because security isn't a black and white matter either.
Privacy isn't dismissed. You just value specific parts of your privacy differently to others. Kind of like those people who protect their telephone numbers as some kind of private intrusion and can't come to terms with the fact they used to be published in big books along with their names and addresses.
I have a Nest. My nest account shares my email and password with my slashdot account. That password hasn't been changed in since I registered the account back in god-knows-when. Given that access to my Nest account would tell you when I'm not home I don't care about security right? Well maybe my "security" is at the building entrance, at my front door, in the trust of our close neighbours, or in the slobbering drooling teeth of my dog.
The London Underground is a mass of interconnecting lines, and you can literally enter into the system at 7am and exit at 7pm
Yes but would you. I mean if the purpose for this is improving the flow of commuters then you'd focus on the shortest time and scheduled path between any two stations. Consumers on average aren't stupid enough to want to spend any more time in the tube than absolutely necessary. Whether someone has fallen asleep on the line, or is going around in a circle really shouldn't matter for any of their scenarios.
We're talking several ships in the ocean simultaneously, not sure if you've noticed but that's not the vicinity of your house
Re-read my post. Specifically about a system with the antenna disconnected being enough to play around in your local house. I don't think you really appreciate just how weak the GPS signal is when it hits the ground. It's somewhere in the order of -130dBm everywhere. To put that in perspective it's about 1000 times weaker than the point where your phone goes from showing no bars to showing no service.
Being able to fool multiple ships is not a case of any technical feat. Throw up a dipole and put a few watts up it, done.
You need at least 2 antenna's
Because after doing it with one the second one becomes some insurmountable obstacle? Also no you don't. You just need to fool the transceiver. Most of them will simply believe the strongest signals to be the true ones.
How will you reposition a GPS signal for the area of a small city with the SDR?
Dunno, take your pick. There are a variety of open source programs to spoof GPS signals using SDR. There are a constant string of articles about how to do it on hackaday for various purposes including (and disappointingly for our species) for the purposes of making your Pokemon go character walk without having to leave your basement.
GPS has fairly decent signal discrimination (it kind of has to) and you need to be able to imitate not one but at least 3 around the poles if not 5 or more elsewhere separate GPS signals to be able to reposition a thing and it knows how to ignore 'bad' signals.
No it doesn't. In fact GPS receivers have no discrimination for the origin of the signal. All the discrimination is part of the protocol itself, and you can simulate all the satellites all over the world at the same time if you really wanted to. The math doesn't care.
Additionally, fixed GPS systems on boats have somewhat directional antenna's so you need to have a lot more power to be able to influence those.
Yes they are directional. But rarely with a gain larger than 2. Especially important with shipping is that they pickup signals from the entire horizon given the patchy GPS coverage in some parts of the ocean. The kinds of antennas that prioritise high-gain are actually in a different kind of shipping: namely in vehicle GPS systems from delivery companies.
They kind of expected one or more satellites to go haywire in their lifetime and non-consumer equipment is also built on the premise that other things in it's vicinity may go haywire.
Satellites going haywire is dealt with through overlapping coverage zones. Consumer equipment going haywire is dealt with through strict enforcement of regulations, and GPS systems going down is precisely why there's a major crackdown in some parts of the world right now on those cheap nasty 1.5GHz video transmitters you get from China.
GPS on a physical level has no strength. GPS on a protocol level has no protection (except for the military and that only covers faking signals not causing signal outages). And above all, it is incredibly simple.
I do really like the University professor's comments about it being sophisticated and needing atomic level clocks, since a) no you don't, you just need to generate suitable timecodes, and b) I have an "atomic level clock" on my desk right now. Rubidium standard. More accurate than the caesium fountains in old GPS satellites over a short time window allegedly needed to mess things up. Cost me $50 off ebay.
If I understand correctly you got hooked on Arduino because of it's user friendliness and available documentation. In that regard it's not Open Source you're looking for, but rather very actively used platforms with a large community support.
I say that as a big caveat since ever other person is pointing out that the Raspberry Pi isn't Open Source, but I'm inclined to believe you don't care too much about the fact that the video driver for it is a binary blob right?
The platforms should be chosen with an end goal in mind. Microcontrollers (especially 8bit) > Arduino Embedded PCs > Raspberry Pi / Beaglebone. ARM > STM32 nucleo or something similar, but the communities are no where near as large as the above two. FPGA > Anyone's guess. The communities here are quite fragmented.
While I agree it's great for electronics, it's also an order of magnitude different in league compared to the program a microcontroller with a modular open hardware concept crowd. Definitely required reading for building circuits, but that's not what most people do anymore.
The Arduino / shield concept basically put an end to that requirement. Hell I've been known on occasion to simply not give enough of a damn to design/build a circuit of my own and simply interface with an off the shelf module for the reason of simplicity too.
It's quite going to be quite pointless reading for the vast majority of the current "electronics tinkering" crowd.
If you did with a spoofed signal, you'd need a rather powerful antenna
Satellite signals for GPS are so piss weak that there's enough concern about harmonics from other frequency transmitters causing outages, let alone on the fundamental.
If you want to spoof a GPS signal you can do it with a couple of hundred dollar SDR without an antenna attached and still affect every device in the vicinity of your house.
Perfect. Only this morning I woke up and was thinking, if only I knew what some random person on the internet didn't want, then my life would be complete.
You have completed my life. It gave me such a warm feeling inside that I said "Okay Google, please turn my nest down to 20 degrees. It's getting too warm in here."
I don't have one personally but a friend of mine was showing me what he uses it for. Basically: Anything for which he'd normally get his phone. "What's the weather like?" "What are my appointments today?" "What is the traffic like to work?" "Set an alarm for 2minutes" - more useful than it sounds considering the device is sitting in the kitchen area, followed by a lot of other useful kitchen related ones: "What's 2 cups in millilieters"
but the more neat thing come in interfacing it with other devices "Play House of Cards on Netflix" - TV turned on and started playing the current house of cards episode.
I'm sure more uses will come up beyond turning lights on and off. I anticipate people will treat this like Siri. At first it's a novelty, and then when the novelty wears off the die-hard users will find no end of new useful things for it to do.
He did no such thing, and judging someone based on their level of sarcasm when dealing with a troll rather than their actions just shows everyone what you consider more important.
THAT's a good way of giving up any moral standing.
Slashdot Mirror
and by extension we can stop having software installed with hardware by default (especially the uninstallable kind)?
No and Yes. I think it's a horrible practice to deliver an empty useless device.
But equally horrible is not being able to remove something you don't want.
^ This.
The blame should go on Australia for not protecting one of their citizens against another country.
To be clear are we talking about Australia not protecting a German born, German / Finnish dual citizen residing in New Zealand?
Well in that case fuck Guatemala too, they are just as responsible.

Thank you for making my point. And just like cooking and driving, the hobby of shooting is amazingly safe.
LOL.
Err....as far as I know, in most states you do NOT have to register a gun with the state.
