I've seen companies spend ludicrous sums on TYRING to fit square ERP pegs into their odd ball shaped hole of business processes. Keep customization to a minimum. If you can't find an ERP system out of the box to do what you need it to almost completely, then building external apps to do what you want is not a bad way to go provided you have in-house talent to manage it.
Also make sure the vendor approves of what you're doing in those external apps. You might find them blaming you for system problems and not provide support when you need it most. You can bet the odds of this go up if you outsource the dev work. It's nothing for them to blame a third party they don't have a business relationship with.
Just remember -- external tools are basically external modules that are only dependent on the underlying data. As long as the database schema doesn't change, system upgrades shouldn't have any impact on your external tools.
It sounds like this transformer had its center tap grounded and was the path to ground on one side of a ground loop as the geomagnetic field moved under pressure from a CME, inducing a common-mode current in the long-distance power line. A gas pipeline in an area of poor ground conductivity in Russia was also destroyed, it is said, resulting in 500 deaths.
One can protect against this phenomenon by use of common-mode breakers and perhaps even overheat breakers. The system will not stay up but nor will it be destroyed. This is a high-current rather than high-voltage phenomenon and thus the various methods used to dissipate lightning currents might not be effective.
In March 1989 much of Quebec lost power for the same thing.
They lost power because the common-mode breakers tripped, not because their system was actually damaged.
Chattanooga is a city that has quite a few very wealthy interests that wanted to better their community because they would benefit too. The people that you might normally think of as being against such a venture were not. The broadband is just one piece of the puzzle of investments that have been made with open arms of power brokers.
If you were to have visited it 10 or 15 years ago and then came back today, you'd swear that you were in a different city. The transformation has been nothing short of amazing. And that's why the city is full of tourists most of the year.
For those with access to a supermarket, a combination of lack of time, lack of education, and lack of ability to delay gratification that causes people to eat junk food. Not money.
None of the above. For most poor and even lower-middle class families, the limiting factor is lack of access to food preparation equipment and facilities. Low-income housing often lacks a kitchen. Even if you have a kitchen, one often lacks appliances; trying to subsist on unprocessed food without a refrigerator or a stove is difficult to put it mildly. Families near the poverty line move from place to place a lot, often on short notice in response to evictions. There's no way they could maintain possession of bulky appliances under such circumstances, not to mention an adequate inventory of cookware.
Poor families are really living on the edge, much more than you realize. Once you get to the point where you can't afford a security deposit for an apartment, a lot of options close off. Food preparation is one of them.
Food prices are high, but all of my meals (which are nutritious) cost $1-$2 max, usually closer to $1. You just have to know how and where to shop. Of course, this is the US, which is a first world country...
It is not enough to know how and where to shop. You also, generally, need a kitchen and appliances (stove, refrigerator, etc.) in order to produce nutritions $1 meals. Many poor and even lower-middle class families simply don't have these things. The kind of housing that you can get for cheap is going to be one-room boarding houses with limited access to food preparation facilities. You're lucky to have even a shared kitchen. As for appliances, they're not actually very expensive -- an iPhone costs more -- but poor families generally move far too often (usually involuntarily) to maintain possession of bulky items.
