Now with a bit more of time, just for sake of completeness (from the ARM's System Developers Guide).

"If your code uses addition, subtraction, and multiplication then there's no performance difference between signed and unsigned operation. However, there is a difference when it comes to division."

Consider the following short example that averages two integers:

int average_v1(int a, int b)
{
return (a+b)/2;
}

This compiles to:

average_v1
ADD r0, r0, r1 ; r0 = a+ b
ADD r0, r0, r0, LSR #31 ; if (r0<0) r0++
MOV r0, r0, ASR #1 ; r0 = r0 >> 1
MOV ro, r14 ; return ro

Notice that the compiler adds one to the sum before shifting by right if the sum is negative. In other words it replaces x/2 by the statement:

(x<0)?((x+1)>>1):(x>>1)

It must do this because x is signed. In C on an ARM target, a divide by two is not a right shift if x is negative. For example, -3 >> 1 = -2 but -3/2 = -1. Division rounds towards zero, but arithmetic right shift rounds towards -inf.

It is more efficient to use unsigned types for division. The compiler converts unsigned power of two divisions directly to right shifts.

For this and other fancy ARM insight take a look at the ARM System Developer's Guide, really a nice book: http://www.elsevier.com/wps/find/bookdescription.cws_home/70...

I wonder how people would answer if the implications of the graphs were made more clear to them.

An unequal distribution of wealth, at least in America today, implies that great success is possible (in a system with less income mobility it might imply something else, but that is not the case here). Given the right combination of luck, brains, talent, hard work, or beauty, you too could become fabulously wealthy. Your startup could be the next Google, or Facebook. You could be the next Bill Gates. And if your plans for greatness don't pan out, well, even the bottom quintile has it pretty good compared to most places.

In the other graphs, the chance for relative comfort is increased (assuming a certain base standard of living), but the chance for huge rewards for great success is drastically reduced. In the Utopian version it is non-existent: No matter how hard you work, you will get the same result.

Maybe I am still young and idealistic, but frankly I prefer the first graph. I'll take freedom over security, and a chance for greatness over comfortable mediocrity.

While I agree in spirit, I disagree with your implied definition of the central limit theorem:

"If you have enough observations in a sample, the sample mean will approach the population mean, if the distribution of the population is normal."

That's not even close to the central limit theorem.
I don't know what businesses other people have collaborated with ... but to me the people behind the products I'm using matter a lot, I'm not dealing with faceless entities.

Personally that's precisely why I'm using Postgresql ... I can talk to the core team of developers and get their input whenever I feel like there's a problem with Postgresql. And for a web service we worked on, we even hired a Mysql developer to come and help us (was also on Sun's payroll at the time).

How could I trust a product based on ZFS or how could I trust them to build my products on top of Java or any of their Sun-derived solutions ... when the top talent that worked on those products left?

Not to mention I don't like hypocrites ... before the Sun acquisition they called on Sun to make the JCP more open. Is this an US thing? Can companies fuck with you because it's just business?

Oracle seems to me like a sweat shop. Nothing wrong with that and I'm glad they are making lots of money ... but in my shop you can get fired for suggesting Oracle products, and it's not just me, there's a whole generation of software developers that won't touch their cash cows.

There's a whole generation of developer that have chosen Mysql or Postgres or implemented their own shit, and did not go for Oracle's DB ... that's revenue and opportunities lost for them, and I'm only seeing this trend getting stronger.

Android is solid, WebOS is solid, and Blackberry’s new OS/UI looks great too. Nothing I’ve played with is better than Apple’s iOS, but a lot of the alternatives are approaching “plenty damn good” status.

That's Apple's edge. No one in their right mind can call the technology that RIM, Palm, or Google come out with as anything but outstanding...yet Apple still has that edge and their products are always "great" while the others will always be "plenty damn good".

Perhaps it's because they control all the process (sans manufacturing). Maybe it's a different philosophy. But it really seems that no one cares about every minute tiny detail like Apple does.

Apple has always cared about the small things. That's why I don't see their perceived reputation going anywhere. As long as they keep doing that, they'll still be different.
I don't see how you could run apps on an AppleTV with no touch interface, different screen resolution, and no HD space. Am I missing something?

Assuming, of course, that PG&E doesn't get any kind of subsidy itself. This is almost certainly not the case.

I can't find directly comparable data; the closest I could find was something[1] from the U.S. department of energy that claims a 2007 allocation of about $10 billion to areas other than research, end use, and conservation. If you believe Wikipedia's figures[2] of 29 PWh in 2005 and assume that 2005 and 2007 are similar enough to compare, that's about $0.36 per kilowatt hour in subsidies. If we assume that PG&E is typical, it implies that they're already charging $0.36 less than their "true costs" as a result of federal subsidies.

It's an extremely rough figure, and I suspect a proper breakdown would give a much lower number, but it does demonstrate that removing the effect of subsidies is not so simple.

edit: Helps if I actually include citations.

Depends on the website - assuming you're asking re: HobsonFiles - I would estimate that you're ok moving to the larger screen sizes due to the likely more technical audience you're building for.

In my own experience planning around 1024x768 in general can be beneficial because:

a) It allows you to better focus your content rather than having space to fill which often leads to overdesign.

b) Often users with higher resolutions are either (a) Older (b) Less sophisticated which depending on your service can be some of your best converting traffic.

c) Interesting note from Nielsen along these lines suggesting that for users < that resolution they will absolutely not scroll to right, so dont put any important content to the right http://www.useit.com/alertbox/horizontal-attention.html
I think high contrast text is good typography.

But for people in other, "left-brained" professions, enhancing creativity is less important and engaging people is less important, so it makes sense that they would see design rules as irrelevant extra work of little value.

If you assume my work requires no creativity, or that I think design rules are irrelevant, then you are mistaken. I don't like design for the sake of design. I do like design that looks good and enhances a things intended purpose.

It's plausible that a realisation that income inequality _within_ the US has less extreme consequences for people at the bottom end of the scale than income disparity between the US and the rest of the world explains why the US population appears to downplay the level of their own inequality.

He'll be making capital gains money, not income, so this move will not help him. (I had the same thought re: the move but was corrected on Twitter by a friend who sold his startup - Newsvine - and lives in Seattle.)
Thanks for an intelligent response.

I think there are multiple definitions of "merit" at work here. The form of merit which is chosen and admirable is not necessarily the same as the "merit" in "meritocracy".

I agree that merely being born with an attribute is not really "merit", but on the other hand I think a "meritocracy" is about rewarding ability, not "merit", and perhaps needs a better name.

Wikipedia defines it as:

Meritocracy is a system of government or other organization wherein appointments are made and responsibilities assigned to individuals based upon demonstrated intelligence and ability (merit).

which is different again to what I meant... the form of "meritocracy" I mentioned would exist even in the absence of society. If the world consisted of a bunch of individuals on isolated and identical islands who never interacted then it would be a perfect "meritocracy" in the sense I meant it, because each would acquire wealth and quality of life depending only upon his own ability to hunt, gather, build shelter, et cetera.

Also, it's not just about the technology. Apple has created a very desirable brand that people want. A lot of Apple's gadgets have become status symbols.
Yeah I think this is more of a PR stunt than anything else. The technology has potential but at the current moment, but it isnt superior than what is out there. Biomass is green but there isnt enough of it available for cheap. So I think Bloom boxes will have to use natural gas (which isnt green) to scale.
The last link in the article seems to answer this:

"A 100-kilowatt Bloom server array costs around $700,000 to $800,000, or $7,500 a kilowatt, after incentives that cover around 50 percent of the costs"

Ning decided there was no profit in "Free" web hosting - even with all the advertisements they plastered over the pages. They shut it all down and only support paid hosting.
FWIW I was once in the same boat as you. About three months ago I decided that being able to create decent designs was a tool I needed to have in my toolbox.

What worked for me: I learned to draw. It took a lot of practice as I really sucked initially. I recommend getting a notebook with grid lines and a ruler.

It takes a lot of patience to pay attention to all of the details but it pays dividends. With drawing as an intermediate step between having something in my brain and having something in pixels I'm much better at capturing a vague visual concept, iterating, and bringing it to life.

I suspect this process will be different for everyone- this is just what helped me (after years of limping through the design process).
I'm not sure how the "wealth" is being counted in these distribution of wealth plots, but I'm fairly sure it doesn't account for future income.

If it did, I'm guessing the distribution would look a lot more equitable.
Heritability doesn't need to be genetic.

Many of the traits that hugh3 refers to may well be a matter of culture and values. These are heritable traits, in that children tend to acquire them from their parents. But they have nothing to do with DNA.

Thus, there's very little in this claim condemning a person's offspring, for all of eternity, to menial drudgery, simply due to an accident of genetics. The children or grandchildren can learn a different way of life, and improve their lot -- and pass that on to their own children.

It's been observed that if you (1) finish high school; (2) get a job; and (3) get married before having kids, the chances that you'll wind up in poverty is virtually nil. This says nothing about ethnic groups, the finances of your parents, etc. It's just a matter of displaying the values that have proven to lead to success.

It's a bit different - Apple had the advantage of being the first on the market. They could afford to take some time before shipping the devices. Everyone else has to play catchup now; the longer they wait, the stronger the iPad becomes.

Apple does however release most of their products shortly after they are announced (new ipad nano, apple tv, iphone4)
When I see a pop up on an article, I generally close immediately. It is pretty clear that they are simply trying to monetize my visit, and whatever content is there is just more bait for that. I will put up with banner ads to some extent, but as a general rule if there are more ads than I feel like there need to be, or if the content of the article is broken into different 'parts', I'll just close on general principle.
Southern white men were not secure in their station during the 50's and earlier?

Regardless, you are ducking the meta question. Is "a mob might become violent if we don't do X" a good argument for doing X? I.e., if angry racist mobs start rioting over a black president, should we impeach Obama? Should we engage in appeasement, paying each racist $500 to go home (perhaps levying a tax on blacks to pay for it)? Similarly, should we ban criticism of Christianity if Christians form lynch mobs of their own?

Which angry violent mobs should we surrender to?
There is no such thing as 'trying.'
I don't think we'll settle an argument here, but I'll say this: The large majority of payday loans are repaid. So long as (1) the borrowers are well informed and (2) there is healthy competition between the loaners, payday loans are good for society. They allow people who otherwise wouldn't get credit to float over rough patches.

Let me ask you this. If you are poor and living month-to-month, and your uninsured car--which you need to get to work to continue earning money--is wrecked, what do you do? Not everyone has families to help them in this situation.
If it's hacked, people could write software that would interact with AppleTV's API's, namely the one that interfaces with the remote control.
I've already pointed out that if Arrington's complied with the tax rules and standards, his action have met one definition of fairness, which is not at all beside the point. To argue fairness or unfairness by other definitions, you have to take a position on those laws. Otherwise, you rule out such judgments, which leads us back to the question "did he play by the rules?"

It depends on the effect you want. Since I usually want the details to be highly visible, I usually go for a background the same color but a shade lighter than the major color in the photo. That minimizes the contrast between the photo and its background, bringing out the details within the photo.

Marshall Kirkpatrick: What The TechCrunch Deal Means To Me
OK. That sounds like a reasonable conclusion. I wouldn't be surprised if they came to a similar one.

I must admit that I find it amazing that blogs or even Facebook make as much money as they do from advertising. Google I get. I semi-regularly click a Google ad, because they are relevant. But I've almost never seen a blog ad or Facebook page ad that had content worth clicking. The exception to this are specialty blogs, like Engadget. But most blogs aren't Engadget.

With that said, clearly Facebook is making a ton of money. I'd love to see the data on what actually gets clicked.
Just because you are paranoid doesn't mean they aren't out to get you.
It depends upon the implementation of the "backdoor": If the government had a heavily guarded server that held the only copy of a private key that was the pair of a public key that all asymmetric encryption added as a mandatory target (just like a PGP recovery key in the enterprise), and law enforcement could pass messages through it, with a coupled court order and with civilian oversight, and public text popped out, it could be secure.

But that isn't how they would do it.
Reminds me of an old political joke, "They framed a guilty man!"

Conspiracies and poor behavior are not mutually exclusive.

I know how much you want to believe, but wanting to believe is not going to make it so. At the end of the day, Wikileaks has to be about more than personalities if it is going to succeed, conspiracies or not.

Put differently, you can only frame a person who has made himself the image of the organization. Wikileaks should have never allowed Assange in this position.

So fix the error and move on. No harm, no foul. The only damage to Wikileaks occurs if they sit around and do nothing except for form a circular firing squad.
