Yes, typically a sales (consumption tax) does effect to poor more than the rich, because the poor tend to consume 100% of their earnings to survive, whereas the rich only consume a very small portion of their overall earnings.

The Fair Tax attempts to address this via 2 mechanisms- first, it does not tax used goods. Poorer people are more likely to buy used goods than new ones.

Second, the Prebate. Under the Fair Tax, the a prebate is given, based on the Federal Poverty Line, and the amount of tax that would be paid if a family spent up to the federal poverty line. Families that are spending less than the Federal Poverty line actually would pay negative taxes, and those spending more, would progressively be taxed more.

As written, some analysts of the Fair Tax have criticized it for putting the squeeze on the middle class- because many spend everything/most of what they earn, but earn well over the poverty line. Whereas the wealthy still consume very little of their overall income, and the poorest of the poor pay negative taxes.

I would tweak the prebate a little from this model, requiring the legislature to specify the prebate level each year as a part of their budget. This means they can't hide behind tweaking the way the poverty line is calculated- they have to make the decision directly, and be held accountable for it. I would also require the legislature to set the actual tax rate annually or at some other regular interval.

Why NetBSD?

- For its excellent backward compatibility: NetBSD 6.1 is still able to run a.out binaries built for NetBSD 1.0

- For its system-independant build system. Building NetBSD needs a POSIX system with a C compiler, which does not need to be NetBSD. It first builds the tools for the host, including the compiler itself, and then the target NetBSD system, which may be for another CPU.

- For its machine-independant drivers. Have a fancy platform with an odd CPU? If NetBSD has a driver for a chip, it will work as is, no need to port it

I wonder if young adults in two or three decades, the ones growing up with netflix and amazon instant video accounts, will have to say the same.

I know I cannot already, since I grew up without cable television and had most of my childhood televised entertainment provided for me through public broadcasting and rented/bought VHS. I'll admit that my circumstances were unusual though.
"The Nag Factor": https://www.youtube.com/watch?v=Hi63rXnuWbw

You don't have to accept the position of the documentary, that the corporate form is intrinsically a bad thing. But tell me that the marketers behind the "Nag Factor" report don't disgust you.

It is nice to imagine that each family is an island of rationality, well-informed about choices and their eventual effects, never choosing the easy path, immune to marketing and peer pressure. In the real world, things are a little more complex. And the marketers behind reports like "The Nag Factor" make millions by subverting family relations to serve their purposes.

It is good to be skeptical of regulation, but this is so clearly a case where more good can be done than harm.
The counter-argument is that advertisement is speech, even if it is undesirable, and that speech is information.

Parents who do not wish their children exposed to advertising could use the same rules they would use to prevent their children from being exposed to violent media and profanity.

I think the solution is for parents to simply start thinking of media portraying drug consumption and media portraying Twinkie consumption as logically equivalent, and for parents to stop paying for an information service to deliver them such media (television), and to demand the market provide a new information service which more adequately matches their preferences for media (a kid-oriented Netflix?).

This solution does not require a state to monitor and decode the nutritional value of information transfers.
Yes, but not by default.
Well no, you just made my point for me. See, if that is gluten free, then I didn't know it. I am not gluten free I just eat healthy. I have accumulated knowledge of a healthy diet rather than a gluten free one. Good point though.
What I would like to know is, how do you determine which is better? Is it speed or something else?
Following this train of thought to its logical conclusion: Without children's entertainment, kids would be forced to read free books from the library or go play outside. The horror!

Look, shared cultural nostalgia is great, and all, but I'm not sure that makes for a good reason to allow advertizing to kids.

If you are earning money from this line of work, you owe it to yourself to buy a proper device. In fact, you owe it to yourself anyway - the iOS simulator is terrible. The performance is hilariously unrepresentative, the touch simulation woefully limited, and you can't even play any games on it.

So, instead of spending all this money on this fancy new Macbook Pro, why not just buy an iPad? For the money you've spent, you could have bought an iPad 4 AND an iPod Touch 5G AND an iPod Touch 4G, and you'd still have change for the bus home. Probably even a taxi back, in fact.

Your new collection would cover every possible aspect ratio and resolution of the devices that your customers are likely to have, and do a good job of covering the performance bases as well.

The biggest strike against the Moon is gravity - its gravity well is deep enough to make rocketry expensive, even if nowhere near as expensive as on Earth. Even very large asteroids are mostly much less massive than the Moon.

For the same reason (mass), asteroid mining is probably more lucrative than Lunar mining (barring materials similar to Helium-3). The Moon seems to have a less diverse composition, with some useful minerals (which are mostly more massive) buried beyond easy reach.

The truth is that the Moon is more like a planet than like an asteroid. It is easier to reach.

What makes you think taxes should be easy? Defining income is hard. Defining income in an international context is exponentially harder.

The corporations in this case are not using obscure loopholes to avoid taxes. They're taking advantage of necessary complexities in the tax code: that it taxes net income rather than revenue, and that it taxes income reasonably related to the jurisdiction and not all income everywhere. What's complex is the situation: accounting for the income of huge multi national businesses that have customers and employees in dozens of countries, whose income involves transactions with pieces spread out all over the world.

Its like saying that the Windows kernel should be simple. Sure, as long as you give up decades of backwards compatibility and a multitude of hardware support you could make it simple. Analogously, the only way to simplify the tax code might be to give up on taxing corporations. But you can't jump to the conclusion that the complexity is unnecessary.
Define "advertising to children".

Does that mean that TV shows targeted to children can't have advertising? Goodbye kids TV (not all of it is bad). Venue aside, what are the signs of being targeted to children? Show too many kids in the frame, the wrong color scheme, the wrong narration style or fonts? How close can you get?

We talked about "airtightness" in the taxation thread, but I'm realizing there's another issue. If the law isn't carefully defined, it could be possible to interpret nearly any advertising as being targeted, in part at least, to children. This is the kind of thing that will slide toward more restriction under the pressure of various kinds of activists, once we get the idea that we can ban advertising based on its audience.

If the beef isn't beef, you can't really count on any of the other food integrity items - like freshness - to be accurate either.

Should We Be Free To Be Anonymous Online - High Tech Point
I generally agree with you, but I don't think this:

> the population is acting entirely naturally and appropriately given their adaptation to specific evolutionary conditions

is the same as, or even necessarily implies, this:

> there is nothing wrong

I would say we're surviving rather sustainably right now, in the sense that we've adapted to our environment well enough where it isn't really a hindrance to our propagation as a species; but I highly doubt it's even close to being optimal. In the same sense that having long life expectancy doesn't necessarily imply having a good quality of life.

The problem is that we're too quick to assume that we're already living in a 'future' where we know everything, and that things have been distilled to be so convenient, that it all had to be 'proven' or something by now, right? It plays out all the time: "Oh look, this conveniently packaged product has 0 carbs! Awesome, I can eat a ton of this now, cause I just heard of a study that said carbs are bad." Except that the product label is misleading because it only accounts for one tiny serving that was specifically chosen to fall below the "0 carb" requirement guidelines (which do have a bit of wiggle room), and that study was actually sponsored by the company who made that product you're now looking at. And this happens all over the place.

It's unfortunate, but it does seem the whole setup we have going right now might be a bit too shaky to really say much conclusive about nutrition. Nutritionists aren't necessarily doctors; Doctors aren't necessarily scientists; and Scientists could always be swayed by the entities funding their research -- research which can go on to live safely in journals probably without many attempts at reproduction, so it's ok to fudge the numbers a tiny bit if you need things to work out a bit more.

Despite what it sounds like, I'm actually not very cynical; I just think we need to gain a bit of perspective about where we are as a species right now. We'll figure it out eventually, but it is admittedly kinda tough to navigate the seas of nonsense out there right now.
That's right around the age when children should start to be able to handle sequenced events (mine is 3.5 years old and definitely working through it.) Say something like "first, we'll read a book. Next, you can play a game on the phone. Then, it's time to have dinner." Whenever you transition, remind the kid of the sequence. He'll start to get comfortable with the routine of doing something for a while and then moving on to a different task.

Some kids respond really well to a "visual schedule", where you have pictures for each event with velcro or magnets on the back, and a board to connect them to.

It can and will be a battle, simply because it's hard for a little brain to develop things like impulse control, delayed gratification, and patience. But it's important for your son to learn it, and this is a great age to work on it.
"Why should it be illegal for children to drink alcohol? Their parents should be permitted to make their own choices with regard to the beverages their children consume."

I think you mean this to be sarcastic and obviously wrong, but many states in the US permit parents to give minors alcohol (http://en.wikipedia.org/wiki/File:Underage_consumption_map_2...) Some states permit this anywhere (including in pubs), others restrict it to the home. This is considered entirely reasonable by many, dare I say most, people.
Yes. Assuming that, it's good. I think that assumption is likely to be invalid in many cases, though.
I thought we all knew this?

Tax in the UK makes me very sad. For businesses big and small, and for individuals like me, it's a huge burden.

A lot of business owners in my town have been forced out of business by local taxes. They lose business to charity shops, which sell donated, or sometimes new items, and pay profits to charity. They do not pay local tax, and often do not pay rent [1]. In some cases, after paying much of the money to the owner, that charity profit can be slim[4]. It is hard to compete with those who do not pay tax. It is not a level playing field.

I'm sure that those trying to compete with Google, Amazon, and similar large companies that pay very little tax feel the same way.

The times article says "Although Google’s London sales staff would negotiate and sign contracts with British customers, and cash was paid into a UK bank account, deals were technically booked through its Dublin office to minimise its liabilities here. Jones, a devout Christian and father of four, is ready to hand over a cache of more than 100,000 emails and documents to HM Revenue & Customs (HMRC), detailing the “concocted scheme”. "[2]

At the same time, Google's CEO made a thinly veiled threat to withdraw work from the UK if the government here plays hard ball on tax. BP would claim that fines made against it in the US were politically motivated[3], and with some credibility. I think that whether Google is fined in this case will be very much a political decision. Which perhaps supports your point.

This was my first reaction, as well. This goes especially for large datasets. If you are making linear passes over very large databases, I don't think I see much advantage in using a DB beyond possible benefits of shared storage.
I wonder how much of the $2k decrease could be contributed to geography? I think we are seeing more opportunities for technical jobs throughout the US, lowering the percentage of developers that need to be paid a Silicon Valley wage.
I believe that the brain changes between the age of 15 and 30, and I also believe that most people's lives changes between those ages. I'm not so convinced that the former cause the latter, especially without any kind of scientific evidence. There are a lot of things that change socially over that time period.

The author's take on the amygdala is also pretty weird. Sleep, hunger, and sex are all functions generally associated with the hypothalamus, not the amygdala.
Yes, it's hard.

We can't experiment directly on humans - we can only look for correlations, which always causes trouble with determining causality. Biological questions are inherently complicated, so any hypothesis is necessarily little more than a stab in the dark, even if we had the ability to compensate for genetic variation et cetera, which we most certainly don't. Large-scale studies are expensive, time-consuming, difficult to organize, and would inevitably end up politicized from 200 different directions, and then driven into the ground in the next campaign season.

In short, any and all dietary studies are doomed to be 99% failures.

But that 1% is important. I don't think there's much question that we have a better understanding today, of what constitutes healthy food, than we did 50 years ago. We know, in particular, that foods rich in certain substances (I don't want to try to classify them all in one or two words, because I don't study this stuff and would get it wrong - I'm talking about tradition "junk foods" and sweets, like cupcakes and potato chips.), are strongly correlated with a wide variety of health issues, the incidence of which has increased over the last several decades. Furthermore, these foods are inherently attractive to children, and (perhaps more controversially?) display limited addictive properties.

Yeah, our knowledge is limited, and yeah, we'll have missteps. But I don't think this is "premature optimization" - the program's running really slowly, and everyone's complaining about it. We don't understand a lot of why it takes so long to finish, but there is something we can do that would probably make it at least 5% faster. Why not give it a shot, and then go back to profiling?

Oh, and have an upvote, for contributing to the conversation. Because that's the etiquette around here, although some seem to have forgotten.
It might be wise to contact DigitalOcean support (or on their forums) before posting this on a public forum that they probably will not read. Even if you are completely wrong, there is no problem in letting their support know.

I'm really hoping Yahoo the best. Although they have no products, that I'm aware of at least, that I'm using, I have used Tumblr briefly. Like some others here, when I heard Mayer was appointed as CEO from Google.

I thought that was awesome for the company, and even though some of the devs didn't like the HR changes, it does show her commitment to change that is badly needed.

What I will give Yahoo the biggest credit they deserve is that THEY ARE making headlines and becoming a common topic of discussion. I just really hope that Yahoo does cultivate Tumblr (even though I think the acquisition is over priced to make headlines) and carve a strong niche as a bloggers goto solution, and that the users don't start a mass exodus.

Advertising is only kinda speech, in the sense that its a proposal for a commercial transaction. The principles under which advertising is regulated is similar to the principles under which fraud is regulated. Its not speech when you propose to sell something to someone that you don't own or that doesn't do what you claim.

I do agree that the end-user usefulness of something like RSS may have been overstated, but RSS remains a useful tool in some contexts. For example, most (all?) Android/iOS news widgets make use of RSS. Google News also makes use of RSS. I'm sure there are many such examples.
