First, ignore the people who just want to shit all over you for making more money than them. They don't know anything about your situation and aren't qualified to comment. Savings and cash flow are two entirely different things, as I'm sure you know.

Switch wives, really.

(Consider this: A Tesla automobile IS AC motors driven by inverters from batteries.

S-sh-h-hht. Inside the batteries are actually weighted flywheels spinning at 50Hz. That's why you "need" to brake as advertised, it really is to keep the car going.

His paper on game theory is his Ph. D. thesis. Just the tip of the iceberg this mathematician was and could have been if the illness didn't stopped him.

Somehow intellectual brilliance seems to have its way with mental stability, let's just hope some brilliant mind will discover a treatment some time in the future.

Where the fuck is your pascal snippet reading from?

It's reading from System.in, whatever that is. You'll need to guess or look read() up. Once. After that, you'll know when and how to use it.
You see, because in these Pascal times, there was no IDE with auto completion or snippet compiler (Lambert's ABC was one of the earlier).
After years away from Java, I don't remember or guess to use both InputStreamReader and BufferedReader,
because it's simply anal.
Besides that, there aren't many languages that encourage red tape and overengineering like Java does.

-- all in one language with a common syntax.

that's the bloody misconception; a perfect all-in-one fits-all universal command line interface.
it's the tooling's limitations glued by scripting language you choose that leads to unintended but creative and useful matter.
the powershell's achilles heel is just that, the power of all the master of none.

Hopefully this will put an end to one trucker passing another trucker because the first one is driving the speed limit and the other one wants to go 1 mile over the

The trucks are rev- and/or speed limited (at least here) to 55 mph.
It's just like Tour de France, truckers lurk in each other's jetstream, because it's easier and economical to drive next.
To change heads, the truck needs to overtake without the tail losing momentum.
I doubt a computer would do it more efficient, a train will.

Do you have a better and more reliable tablet system in mind, or are you suggesting that they should have stuck with the 35-pound suitcases full of printed material?

It takes less than 1 mins of googling for rugged laptop/tablet or whatever, and I'm not even qualified to make such as decision.
(e.g. panasonic toughtablet)
something pretty vital to ops should have had more consideration than guessing a popular consumer item will do.
What the fuck are they thinking when replacing critical units?

What fucking idiot modded this informative?
