A sprinter runs 100m in 10s. How does the average speed of the sprinter compare to a car speed?

There are 3600s in an hour, the sprinter runs at 36kp/h.

Before the metric system there were many, many versions of mile and other measurement units. In northen europe we had russian mile, british mile, swedish mile, danish mile, finnish mile, german mile, nautical mile with distance ranging from 1.5 to 11km. Without metric system the trade with the rest of the world would be really difficult.

Comment Re:4.5TF, single or double precisions? (Score 1) 176

It's been a while, but better late then never.

The 4.5TFlop is single. It is useful for tasks such as artificial intelligence. I used a convolutional neural network for aerial imagery classification and I got over 80 times more performance out from a GPU (more importantly over 30x improvement in performance per watt department). However, it is much more difficult to achieve this peak performance on a GPU than on a CPU, mostly because of the memory latencies. The CPU has advanced caching mechanism, that is not present on GPU.

You are correct, the double precision performance is more like 2TF, which is still a HUGE number. It beats any processor in the market by order of magnitude.

Federal Court Tosses Colorado's Amazon Tax 229

suraj.sun writes, quoting the Denver Post: "A federal court has thrown out a 2010 Colorado law, which had already been temporarily blocked in federal court last year, meant to spur online retailers like Amazon to collect state sales tax. 'I conclude that the veil provided by the words of the act and the regulations is too thin to support the conclusion that the act and the regulations regulate in-state and out-of-state retailers even-handedly,' U.S. District Judge Robert Blackburn wrote in his opinion. The law and the rules to carry it out 'impose an undue burden on interstate commerce' and are unconstitutional, the judge wrote. The tax mainly affected online sales of out-of-state companies that have in-state affiliates, usually generating sales through links on their websites." I wonder what this means for the plethora of similar bills in other states. Will Amazon continue to call for a national Internet sales tax if they are all struck down?

My nexus s used to lose connection to cell towers with android 2.3.1. Apparently a subsysem had crashed an the only way to restore the connection was to restart the phone. The crash was always silent, without any notification, I usually noticed it when I tried to make phone calls. Often (about every other week) I spent days without connection before I noticed it. The problem was not limited to my phone and it reocurred with firs vanilla 4.0 firmware.

Being able to receive basic phone calls does constitue as "decent function".

Comment Re:Two-dimensional? (Score 1) 160

It's not two dimensional if it has a measurable thickness, which you stated in that same sentence. Unless you have a different definition of "two dimensional" than the rest of us.

It's two dimensional in sense that the third dimension is insignificantly small relative to other two dimensions e.g. it's flat. Also keep in mind that flat does not mean planar, for example earth is flat in spherical coordinates (r=const).

What I find even more disgusting is the following:

We don't have an obligation to solve America's problems. Our only obligation is making the best product possible.

The core ideas behind capitalism are heartless. You must either participate the lottery called "American Dream" or accept socialism. I will be the first one to welcome you to EU if you choose the latter.

Well apparently corporations are people too

It's not true.

The biggest problem with business today. Not just shortsighted and focused on short term profits, but the "Fuck America" attitude as long as it makes them X amount of more profit. Profit at all costs.

Don't be so modest, the attitude they teach in business school is "Fuck the World".
