Comment Specs seem a little weaker (Score 1) 133

Apart from the display, the specs seems bit weaker on the Dell - the Macbook Pro has more storage capacity, and a faster processor even in the base configuration.

Also the Macbook Pro 15" now has the ForceTouch track pad, which will be more useful over time (and Apple makes excellent trackpads anyway, Force Touch or not).

I have a Macbook Pro 15" Retina currently, that I use in non-scaled mode (so I get 1:1 use of the pixels). I'm not really sure how much better the higher resolution would look on that small a display.

That assumes that the business can raise prices without consequence, which is an invalid assumption.

Only if the competition can avoid the taxes. If all of the players in the market get hit with the same taxes, then all of them absolutely can and will raise prices, and there will be no consequences.

Taxes are a percentage of profits, and are not deductible from revenue when calculating profits. So if Amazon raises their prices (and, assuming no change in consumer behavior, their revenue) by 10%, they also increase the amount of taxes they owe by 10%. So now they have to raise their prices again to cover the additional tax, lather rinse repeat.

This is a standard financial calculation, and a trivial one. The tax is 10%, so the increase is 10%, but there's 10% tax on that, so 1%, meaning the increase needs to be 11%, continue ad infinitum (literally). In other words, the new price needs to be 11.1111...% higher than the old one to keep profit margins unchanged. More generally, the increase needs to be the sum of the infinite series with terms r^n. This series is convergent if r < 1, and converges to 1/(1-r). So for a 25% tax, the company needs to increase prices by 1-1/(1-.25) = 33.333...% to keep profit margins unchanged after accounting for the new tax.

Of course, it doesn't quite happen like that. In practice, companies don't instantly raise prices. They do take the hit for a while, where it gets absorbed by the investors, not the customers. Then they allocate a portion of the losses to employees, in the form of reduced raises, or benefits. Then they raise prices. But eventually they get back to a steady state of roughly the same return on assets that they had before the tax hike.

Specifically, all corporate taxes paid come from three categories of individuals: consumers, who pay higher prices for items to cover the taxes; employees, who make lower wages to cover the taxes; and shareholders, who earn lower returns (and note that the two former categories are often also shareholders, via their pension plans). Suppliers can also lose, but they're generally corporations as well, with their own employees and investors who actually eat the loss. In the long run, though, the investors don't lose because capital flows away from lower returns and towards higher ones. So companies must find ways to keep their returns up to somewhere near the mean rate of return.

Once you understand that no taxes are paid by corporations, ever, then you should also recognize that corporate taxes are not only ultimately paid by individuals, but the individuals almost never realize they're paying it. How many people know their prices would be lower, wages higher, or pension more secure, if it weren't for corporate taxes? And, therefore, how many voters have any interest in opposing corporate taxation? To politicians and voters, corporate taxes look almost like free money. Ratchet up the corporate taxes and no people get hurt, just those nasty corporations. (Actually, politicians sometimes get even more value out of threatening corporate taxes than enacting them, since it tends to encourage said corporations to buy off, er, donate to their re-election funds.)

I assert that while taxes are necessary, the electorate should see and understand exactly what they're paying, so they can evaluate the value they're receiving for the money they're paying. Hidden taxes are evil, and therefore corporate taxes are evil, and should be abolished, not raised.

I was a backer. Were you? Or do you feel compelling to complain on behalf of other people?

Facebook buying them means an investment in learning to program for the Rift is probably 1000x more useful than it would have been otherwise.

I understand people are wary of Facebook, and for good reason. But I have seen huge upsides with pretty much no downside since Facebook bought the company.

If I wanted ritual in my life, I would have become a priest and pursued my career with extreme political ambition so I could vote for the freaking pope.

I guess you've never read an article in your life about mobilizing the voters who are too lazy (or metabolically downtrodden from their Cheetos and Coke diets) to physically show up at a polling station?

Paper is a physical token. Reliably obtaining exactly one unambiguous, untamperable physical token with confidentiality from each adult member of society—the vast majority of which are collected on the same day—hasn't exactly proven to be an easy problem, especially when broadened to include public trust—that every voter understands and believes the process to have all of these properties (to at least a substantial degree).

Electronic voting vastly reduces the complexity on the collection side, but then the tamperability problem looms supreme, but this could almost be solved with enough crypto cleverness, except that the public trust story then requires a tiny bit of numeracy beyond grade six math.

Ritual, however, is accessible to a four-year old.

The same four-year olds who are unfortunately not yet equipped with fully functioning batshit detectors.

I don't want to abolish ritual. I simply want to reduce it to the size where I can drag it into the bathroom and drown it in the bathtub.

Comment Re:but I thought 90fps was the thing (Score 1) 35

Sony's headset is meant to reproject frames before render as needed to convert 60+FPS into steady 120FPS.

That seems fine as far as display goes, but part of that requirement for 90+FPS is that head-tracking is congruent... if "real" tracking only is happening at 60FPS, will the faster display framerate really matter as far as people feeling sick after a while (or in some cases instantly...)

Global warming is a sloooooooooooooooooow process

Not necessarily. Greenland ice core records show that in the past the planet has seen temperature shifts of up to 7 C in as little as 30 years. 7 C is huge. It's like transporting Moscow to Rome. Of course, we have no idea what caused such rapid changes in the past. It wasn't CO2 levels, or particulates.
