Comment Re:Linear regression stumper (Score 1) 222

However, the power of 2 seems arbitrary to me,

It is not arbitrary!. Using the power of two allows a simple, possible even trivial analytical solution of the problem (Matlab and similar have it built-in and can do it in a single line).

Of course you could use other norms to minimize the regression error - l1 norm, linf norm or any other norm in between, or even any other norm you can come up with. But in these cases, you end up with optimization problems that do not have analytical solutions and require iterative approximation of the real solution (unless the problem is simple enough that it can be solved by inspection).

Reference: "Convex optimization" by Stephen Boyd and Lieven Vandenberghe.

The book covers regression problems with other norms than the l2 norm.

When you've gone so far left that everybody looks right wing, maybe the problem is you.

Compared to the political landscape in most other countries, the US has two major right-wing parties. And zero parties of importance that are left wing. Most people in the US (including most democrats) would probably get a heart attack if they talked to left-wing (or worse, extreme left-wing) people from other countries.

Taxation is Theft.

I can live with that, especially considering that a little bit of civilization is provided in return.

What I object to are mind-bogglingly complex, time-devouring, unreasonably expensive bureaucratic nightmares from hell that seem to be purposefully designed to create as much misery as possible.

Typically, prior years kids were $165/yr to file their little returns.

Now picture yourself living on a different continent, with the nearest accessible H&R block office being thousands of miles away, and all the correspondence with the local banks is in the local (non-English) language. Oh, and none of the securities the money is invested in are registered with the local financial authorities, but not the SEC.

Oh, and official translations of the correspondence are on the order of $0.20 per word.

Comment More fuel for the dumpster fire. (Score 1) 449

More fuel for the dumpster fire that is known as "the US tax system".

It's already a version of hell for expats; this change means that you'll be paying hundreds or thousands of dollars just to prove that you don't owe any taxes. And this will be necessary even if you only make $15k a year.
