We had no issues with either commercial GPS units nor with in house GPS units that recorded raw (from the satellite packets) apart from the usual ones (separation of the geoid from "sea level").

GPS near the pole gets more interesting as it pays to have your own translation (or one that you can trust) from raw sat packets directly to polar suitable planar mapping coords (as passing through anything [lat,lon] invokes the curse of singularity).

We had issues with essentially every bit of commercial map related software that took GPS produced [lat,lon] pairs - eg: ARCGIS (1997) when handed a chain that crossed the data line failed on all derived calculations (enclosed area, transient velocity, instantaneous headings, etc).

We were lucky in having fairly extensive in house software and no strict dependence on third party tools (eg: we didn't use Intrepid [1]) and having the ability to find all the points in the acquisition, processing, QC, presentation, and map production software that flipped out on sign inversion and recompiling to correct for those faults on the go.

The interesting realisation was just how many "professional" tools failed to work in that part of the world; see Wingman4l7's comments for a typical "if it works in North America that's all that matters" attitude.

I suspect we have different definitions of hard; text based serial comms protocols can be difficult to parse if you lack a complete specification from the outset or if there are ambiguities.

Hard is using Kalman filters on the fly to correct for the magnetic bias induced by a planes heading whilst correcting for diurnal magnetic pulsing and gathering multiple channels of radiometric data, watching ground separation radar and LIDAR, and doing differential GPS corrections against a base station and using temperature, pressure and humidity to estimate a standard air column density between craft & ground (for normalising gamma rays).

I dont think the OP was pointing to OOP when talking about classes. You can have classes without a meaningful class hierarchy that still conforms to the OP's desired programming style using protocols like the iterator protocol.

When flying, navigating or surveying in polar regions it pays to have control (or an understanding) over the translation from raw sat packets to polar suitable coordinates, when flying at extreme altitudes it pays to have the same as numerous commercial GPS units have altitude and/or speed cutouts.

I'm certainly not talking avionics for commercial passenger craft, I'm talking about the avionics for routine global scientific measurements, geophysics, weather balloons, cheap drones, etc - all of these are application areas where roll your own avionics that aren't written by North American bound myopics are applicable.

I'm sorry, but your view on "extremely reliable and incredibly quiet" is idiotic. Gasoline cars are extremely reliable and incredibly quiet compared to OLDER GASOLINE CARS! Compared to Afghanistan, Iraq is an incredibly safe and quiet country to visit, but for some reason, I'm not planning a trip there anytime soon. Gasoline doesn't even come close to winning internal combusion category. Diesel blows it away in reliability.

Gasoline vehicles have gone from being absolute pains in the ass to maintain (I've worked on and rehabbed many an old vehicle, including mid 80's Oldsmobiles, 70's era air cooled VWs, and mid to late 90's GM vehicles) to significantly less pains in the ass, but still finicky creatures. 4 or 5 years in on modern ICE vehicles, you're going to start seeing problems that can often be expensive. If its not the electrical, it will be failed pump on the cooling system, or even a cracked impeller (now that they are made of plastic).

Can you prevent this all with regular maintenance? Of course, but let's not pretend like this isn't much more complicated than it needs to be. An electric vehicle isn't going to have tubes, pumps, fans, impellers, thermostats, spark plugs, valves,cylinders, ignition coils, injectors, oxygen sensors!!! ($10 part with several hours of labor to replace), catalytic converters... and my god how many other expensive, prone to breaking moving parts can I name.

And then you are sitting there talking about turbochargers? Really?? Do you have any idea what kind of maintenance is required, and oh wait, now we can up our octane to 93, pay out the ass for gasoline, and deal with all the extra wear an tear high compression turbo engines deal with......

I live upstate, and pay about 2.5% of my home's value in taxes. Every time they give the cops another 5% raise, it has an immediate, measurable impact on my homes value. For older people, it makes it very difficult for them to live without assistance.

Income tax is a far more just system. Poor and elderly people pay almost nothing, and everyone else contributes regardless of whether they own property.

I'm in Australia, and our power supply is 230V AC (+/- 6%) (240V was the standard before 2000, but is still within the acceptable limits). Most power outlets are 10A (max ~2300W) but I also have two 15A sockets in my house for the air conditioners (3450W - I also use one to power my coffee machine, which pulls 3200W when warming up!), and could theoretically get a 20A socket (4600W) installed. With an industrial outlet, you can get single phase power of up to 32A (7360W), but I doubt most electricians would install that for you at a house.

So when they did this in 2006, the UN issued weapons sanctions against North Korea[1]. Then when they did it again in 2009, the UN issued more sanctions[2] that apparently NK considered an 'act of war'. From them, the world has intercepted a whopping 6 North Korean boats and 1 North Korean airplane.

Aside from "issuing even more sanctions" what options are available to the UN? Good luck trying to send in a team of people to destroy the nuclear program, that will all but invite a warhead/attack.

Hm. This would have been a lot more convincing if any of the example photos were also of metallic looking things that came out and bent at a weird angle. I certainly understand and am familiar with how rocks may contain different materials that erode at different rates, often leaving protrusions.

It's not clear to me what sort of material was in the rock that would erode around it to leave such a shape that was found. Perhaps on earth if you had a deposit of metal that melted in volcanic action and then filled a crack or seam in a rock which was in a later age pushed up?

This does bring up another point of curiosity - with so little water on the ground, the atmosphere of Mars is likely very dry as well. Would metals oxidize as easily on Mars? Probably not. Perhaps any oxidation that did occur would be little enough to be sand blasted off from the dust storms, leaving exposed metal deposits remaining shiny.
> So for a 1000 mile trip, that is going to be about 6 charging stops.

> 3 hours added to the trip - and probably more like 4 hours when you consider that the Supercharger stations are not going to be located right on the main roadways all the time.

On the other hand, with normal commuting patterns you have to refuel your gasoline car about once every two weeks or month depending on the car and your driving habits. With an electric car, you just plug in every night and never stop at a smelly gross gas station again.

I don't know why people complain that when you use a product for what it's not designed for, it's bad at it. Electric cars are bad for road trips. If you're going 1,000 miles, use an airplane or at least a train.
One important distinction that this article misses completely is that Mr. Heymann is a civil service employee whereas Ms. Ortiz (his boss and supervisor) is a political appointee. The Executive branch is perfectly within it's rights to fire a political appointee at any time for any reason, but would have to show cause to terminate a civil servant. This system exists to prevent partisan patronage at the federal level from bringing the government down on a regular basis.

Paradoxically this means that any effort to remove Mr. Heymann is made more difficult by the existence of a qualified petition for his removal. He would have to have made overt and on the record declarations of ill intent and bad faith for the Obama administration to remove him at this point. Ms. Ortiz on the other hand, could be asked to depart at any point. Although it seems unlikely to happen before she testifies to congress, and is in any event unlikely to happen unless the Presidents political calculations suggest that her absence will allow him to access resources ( of political support ) that are necessary for him to achieve his agenda.

Why is it wrong that NK do Nuclear testing?

I agree NK has some human rights issues, that should be addressed, but testing nuclear weapons is no different to Pakistan or India, and there are no sanctions against them.
They had the dumb idea of using renewable energy for the charging stations and, here's the dumb part, BUILDING THEIR OWN CARS instead of licensing out the battery tech to all the car companies for cheap. It was pretty clear for all the glowing profiles that came out when the company was forming that the guy running it was charismatic but a flaker.
For decades that's been the problem. South Korea's population centers are too close to the North for an attack to be a reasonable risk: even decades-old artillery and unguided rockets can hit Seoul, launched from hundreds of dug-in sites. So things have been organized around trying to pressure North Korea in various ways, either via China, or directly, but without force being a seriously considered option.
Your comment is an example of why this kind of propaganda works. People start hating another country they've (likely) never been to, and likely have no understanding of their motives.

The USA four corners area (especially Utah) has some wonderfully alien terrain covered in formations like this. I've walked over fields of bizarre door handles, thin porches, endless wormholes, and smooth pockmarks. Imagine the signature formations of Arches National Park, but done at 1/16 scale and dotting a square acre. It's amazing what shapes are left behind when a soft, sedimentary rock surrounds and then erodes from denser igneous and metamorphic.

I'm just a guy who likes to walk outside and certainly not a scientist, but this looks very much like a unique and fascinating protrusion of dense polished rock or metal. Simplest explanation and all that.
More and more people are doing it too, I think. I was looking at property records, and a surprisingly large number of them were owned by various "trust"s .
It's the manner with which they're conducting the tests. Do you think nuclear testing should be done in private by an authoritarian regime, or do you think it should be done with the acceptance and supervision of the world's scientists?

It's quite possible that part of Amazon (e.g. AWS) is doing defense contracting, and that the U.S. Department of Defense (DoD) is making Amazon jump through hoops Amazon haven't the stomach for. I'm aware of at least one DoD contractor that will hire Iranian born people, but there's a special background check that DoD requires, and, assuming that turns out OK, there are still some data/projects they're prohibited from getting access to. DoD assumes Iran will blackmail those with family in Iran with the welfare of their families, forcing them to breach confidentiality agreements.

The reviews from Tesla owners who have their own experience with the car in cold weather is interesting.

Can anyone tell me why the car discharges when plugged into a 120V supply? It's mentioned in one of the links above and in the NYT article.

I'm aware that you can't supply much current with a standard 120V supply, but why would it discharge? I would imagine at a minimum you'd have a very slow charge rate, but from these two anecdotes, it appears in cold weather it still slowly loses charge when plugged into 120V.

Is the car constantly heating the battery? I could see that being the issue as engine block heaters draw a ton of current and they take a long time to heat up an engine block. I'm assuming the battery has a lot more thermal mass than a 300 lb engine block.

Right, so it makes sense that the US would be worried... not why the UN should sanction them.

I'm referring to the inconsistency. The implication of what you are saying is: "The UN only intervenes when it suits the US". To me that makes me think LESS of the UN sanctions, not more.
In their last round of tests neither Pakistan nor India performed them "with the acceptance and supervision of the world's scientists".

US intelligence was completely wrongfooted at the time of India's five Pokhran-II tests.
My father-in-law was a VP in Northrop Grumman's space and satellite division. The kinds of projects he worked on were space defense satellites.

Given the types of people I know he met with, this test does not fill me with warm fuzzies.

Gasoline doesn't even come close to winning internal combusion category. Diesel blows it away in reliability

Ah, I see, only the most reliable thing can be considered reliable? More importantly, gasoline engines can be designed like diesels. We have direct injection for gas engines. We have low-rpm torquey gasoline engines (see the slant-6). A key reason diesel engines tend to be more reliable is because diesel engines are often used in applications that demand reliability, while gasoline engines are often used in applications that are willing to sacrifice some reliability for extra performance. Which, mind you, is not something electric vehicles will be immune from.

If its not the electrical, it will be failed pump on the cooling system

And I suppose you think electric vehicles don't have liquid cooling and heating systems? Cute.

Why exactly would an ELECTRIC VEHICLE be less prone to electrical failure, anyway?

talking about turbochargers ... do you have any idea what kind of maintenance is required...

No, I have no idea. In fact, I've never even heard of turbochargers before, I'm not sure why I said that word!

Turbochargers are a trade-off to handle a deficiency. Electric cars make trade-offs too, as they are not perfect either; their deficiencies are simply different.

Oddly enough, I've got a 32A socket hooked up to a water pump. I'm not entirely sure why the electrician installed in, there's no way the pump draws more than an ampere or two.

Thanks for explaining the 240/230v difference, I'd always wondered why it existed.
This is sensationalist news at its finest. There is only one way to confirm that a nuclear bomb test has occurred and it is not by measuring 'resulting' earthquakes. Until either the US Gov't or the very top at the IAEA states there was a successful test, this is nothing but linkbait. Frankly, given the tensions right now between the North and South, and that it seems the North, with the Passing of Kim Jung Il, might be more willing to open up, I find this type of reporting and grandstanding for views really infuriating.

I'm guessing the issue is that NK is an openly hostile country that is not only threatening its southern neighbor but also the region.

India and Pakistan may have a beef with each other, but they weren't a destabilizing force in the region, or maybe more accurately, if they were, it wasn't a huge concern of the superpowers at the time.
