Sure. Some software has to exist to make use of this system, for example something has to create the tag in the first place, and mall ic is a part of that, but the large address space is what makes them possible.

I waffle on this one too. Institutions that do HFT have a huge capital cost and pay large fees before they even make their first trade. They also employ programmers, traders, etc. Basically, these taxes are going to need to sum to something really big to dissuade them. Too small, they ignore it. Medium, the market will just consolidate. Large, you'll stop HFT, but at what consequence? The probability of unintended consequences is high.

This is when I decide I don't really understand the market as well as I think, and I should stop solving the world's problems, and go back to designing circuits.

Personally I waffle on this myself. My instinct tells me it’s bad but then I try to decide what trading cadence I would limit it to. Assume there is a CEO who wants to do something nefarious to manipulate the stock price. If they make a decision how fast can a company actually act on it? Would or could they make the company act on 1 hour boundaries? Even if we limited trades to once per week is that the long term we want a CEO to consider? At what time frame does a stock stop being a stock and convert to something else? Then I decide even by minute trading is not really something that management can even consider, even if they want to, so there is really no point to artificial limits imposed by law and take a more laissez faire attitude.

> Its a ton of random math that (most) of which you don't use again since you use modeling software.

You absolutely need that math because you need to know when the modeling software is giving the wrong answer. You’re supposed to do quick and dirty calc by hand (ok fine I use mathematica) in a simplified system, then you refine with numerical software and compare the two. It’s shockingly easy to get the wrong answer with numerical CAD.

That condition is the key. Are you sure they can do that? It’s very tough to do with certainty.

First off, I admit I didn’t do my homework so I have no idea what I’m talking about, but couldn’t the Turing machine make a Turing machine interpreter and therefore be a self interpreter? It is universal, no?

> "If everyone else is such an idiot, how come I'm not rich?"

Unfortunately the answer to that question is, I spend way too much time on hacker news.

If that’s all you want try an iPad2. I think it would make a better “laptop” than a RPI. RPI doesn’t have a battery.
