While the article, you, and i'm sure more to come keep mentioning the need to "place senors" the reality is any Utility company worth it's salt already has this data logged as part of normal operations through SCADA/DCS systems.

This systems monitor (and log) so many different variables that it forces the companies to store everything in databases for reference & analysis. When it comes to power generation nearly all power generation is done by a "utility" company all of which are heavy government regulated. In a lot of areas it is actually the government which determines bill rates and adjustments to generation capacities (or at least responsible for the play book the operators work by).

It would be far easier and less far fetched to believe that the NSA would have access to theses logs/DBs for what ever use they wanted. Especially with most major power generation sites being covered under FERC regulations and several of the regulation requirements for Reliability requires operators to track and monitor this exact data that the NSA would need.

And trust me when i say that these sites log everything and keep it incase of an Audit. The consequences for failing to be able to provide the data in case of an Audit or Incident Investigation is worse (for the company) than just about any incident would be. They log it, they keep it, even if they will will never look at it again, because the government might come asking for it (and they will give it when asked with no questions as they are required to by regulations).

Honestly going this route i'd say compared to the wiretapping network the NSA has put together, this would be trivial for them to do (not cheap or quick, just not all that difficult).

there are a few reasons they don't make 3.5's

1: physical size isn't an issue, for the sizes they release that people are willing to pay for it all fits nicely in 2.5
2: 2.5's work in more devices, including in desktops where 3.5's live. if noting is forcing the 3.5 usage then it would be bad for them to artificially handicap them selves.

now for your commend on larger physical drives being cheaper. Flash does not work the way that normal dries to.

Normal platter drives the areal density directly impacts pricing as it drives the platter surface to be smoother, the film to be more evenly distributed, the head to be more sensitive, the accurater to be more precise, all things that cause higher precision that drive up costs as it increases failure rates and manufacturing defects causing product failure.

Now in the flash world. they use the same silicon lithography that they use for making all other chips. there are two costs involved here.

1: the one time sunk cost of the lithography tech (22nm, 19nm, 14nm...) This cost is spread across everything that goes though it. And in reality evens out to no cost increase for the final product because the more you spend the smaller the feature the more end product you can get out per raw product put in.
2: the cost of the raw material in. It does not matter what level of lithography you are using the raw material is nearly exactly the same (some require doping but costs are on par with each other). So in fact your larger lithographic methods become more expensive to produce product once there is newer tech on the market.

No please note that in the CPU world where you have complex logic sets and designs there is an added cost for the newer lithography as it adds to the design costs. but for flash sets there is nearly zero impact form this as it is such a simple circuit design.

The question is "high risk of what?"

The answer is credit card fraud.

they might not have the tightest security when it comes to detecting fraudulent transactions

If this was true, then it should be the industry that goes after the company not the DOJ.. PCI-DSS is extremely clear on what the company needs to do to be able to process credit cards. If they are getting ripped off or that company is by action enabling fraud to happen then that company is liable for the charges and fees.

Trust me i've gone through PCI-DSS certification, and it isn't easy.. but it is extremely clear what the ramifications are for failure.

For the temperature, it depends on where you live. If they are covered with snow & Ice then it is obvious, and if the temp is below 0C then it's obvious. but where i live we have a lot of humid wind and bridges. This means you can have black ice when it is 40F or below. funny thing about black ice is it doesn't cover up the road, unless you can catch a glare off of it you can't tell it's there till you hit it.

I think it would be nice to have a color change at least on bridges to show that the surface is below freezing, to warn drivers that there is a strong possibility of black ice.

wouldn't work for most places, but would be really useful for where i live.

Wish i had mod points, first useful example of the actual thing.

They do look quite nice, and i'd love to have them where i live, and if they can get rid of the light pollution by reducing the number of street lights i'd be all for them (and willing to pay extra for it too).

Personally i see more value in the temperature sensitive idea, i'd love to see coloration showing up on roads and bridges when the surface temps get down to freezing. Where i live we don't get a lot of snow and ice, but when we do it shuts the place down because people don't know how to spot, avoid, and/or handle it. Giving a visual indication that conditions are right for ice/black ice would be wonderful.

I remember a few years ago when they did the black out of the world cup in the US. we had a computer setup back in my area streaming the World Cup in ASCII. It was actually quite good and you could follow the game fairly easily.. At one point we had 3-4 of us standing around watching it..

I will say i bought and installed their thermostats, and i do like them. especially the remote control, with my travel schedule..

But i fully agree that things that are safety devices (like fire/smoke detectors) should be as simple as possible.

I highly doubt that they have applied/executed a RAM analysis on their smoke detectors (either do to ignorance or complexity), but my bet is their reliability would be much lower than they believe them to be if they did. and then you have to ask your self. do you want 10-20% risk of failure in a lifesaving device? not a chance.

Personally i think their protect product is pointless, and more of a liability for them and the user than anyone needs.

The other main point i see between consumer drives and enterprise is the behavior. Especially when the drive encounters a bad sector.

Consumer drive encounters a bad sector, it retries for a long time and then eventual remaps it. In the mean time it has stopped talking to the raid controler and gets dropped from the array as a failed drive.

Enterprise drive encounters a bad sector, it relays the write fail and bad sector to the raid controller who then remaps and reissues a write command. Drive never becomes unresponsive and never gets dropped from the array.

In one case you have a degraded raid array and the overhead of a rebuild putting data at risk, on the other you have a log entry/notification of a drive starting to degrade and very limited risk.

Enterprise drives allow you to manage your storage arrays and handle small failures on your time, consumer drives force you to do it when ever even the smallest errors occur.

This matters a lot when you get to larger arrays where rebuild times can be in the days and not hours..

Sure it's just a firmware/behavior difference, but until they allow you to control that on consumer drives, or allow you to flash consumer drives with raid friendly firmwares, it would be unwise to use consumer drives in hardware driven arrays.

This firm can get away with it because they don't use normal raid striping, they use a mixture of software raid distribution logic (reminding me of something akin to ZFS) where you have better separation and control over how things react to minor failures and behavioral differences.

But for most people, we use hardware driven arrays, and in that world enterprise drives win over consumer drives.

Source on the tanker claim?

Also FYI the octane requirement can be related to timing advance, where a lower-compression turbocharged engine with more advanced timing would need higher octane gas to make longer burns from each spark (higher octane gas burns longer than lower octane gas). The earlier spark sets off a longer-burn time of gas timed to the timing, needing the longer-burn ability of the 92+ octane. An old simple truck with 0 BDC timing would be happy with 87 octane, where a newer engine with 15 BDC timing advance would be better with 92+ octane.

While you are correct your numbers are off.. i haven't seen a car thats less than 10 years old with timing at 0 BDC or retard.. a naturally aspirated 90's miata runs 36 advance, and you can safely take that to 39 advance on 93oct and into the low 40's with 100oct
