There's a word for this: fraud.

No, the word is "legitimate". Import duty to Australia basically consists of the 10% Goods and Services Tax, and consumer goods shipped to Australia valued at under $1000 are specifically excluded. This isn't taking advantage of a loophole in the law caused by weird interpretations, it's a very specific exemption.

Celsius? Fahrenheit? Kelvin? Rankine? What kind of idiots are they hiring at nowadays?

When you're talking about those kind of temperatures, it hardly matters. Rock melts at anywhere between 700 to 1200 degrees Celsius. 2000 degrees Fahrenheit is about 1100 degrees Celsius - still hot enough for rock to at least partially melt.

In any case, there are only *two* temperature scales that you have quoted there that result in different answers. The only difference between Kevin and Celsius is the base temperature - a difference of one degree Kelvin is exactly the same as a difference of one degree Celsius. Same goes for Fahrenheit vs Rankine.

But the size of the universe that we can observe planets in is not even approximately infinite. The number of stars within the range we can observe planets in is only about 1e+9 (!!). Small planets like the one in question are much harder to observe and could not plausibly be discovered at that kind of range, so maybe only 1e+6. We have only actually observed the tiniest fraction of that, so much smaller. That 99.99999% would suggest that this planet should not have been discovered. Even if it were 99.99%, I suspect we wouldn't have found this planet. The outliers we're finding at the moment shouldn't be *real* outliers, not in a galactic scale.

You need to learn the math of percentages better and appreciate the size of the galaxy and the universe that we live in. even 0.01% of one million (1e+6) is a hundred planets. Bear in mind that the most distant exoplanet we've detected so far is in a different *galaxy* (21500 +- 3300 light years away) that puts a massive number of stars within range - certainly billions, possibly trillions, not just millions. Remember that there are estimated to be 400 billion stars in the Milky Way alone. Do you truly believe we can only see one out of four hundred of those stars?

When you're dealing with numbers on that sheer scale, you can be fairly sure that even if there's only a minuscule chance of something happening, it will have happened many, many times.

+ - Game developers release cracked game.->

Submitted by ron-l-j
ron-l-j (1725874) writes "The game is called Game Dev Tycoon, and 214 people have paid for the game while 3000 people are running the cracked version. The cracked version was seeded out on some popular sharing sites, and mirrors what happens in the game industry when people crack games. The user base expands without profit. Even offering a DRM free game that allows you to run it on 3 computers for $7.99 is too steep a price for people. The developers are using it as proof that the executable release is dead."

+ - AMD details next-gen Kaveri APU's shared memory architecture->

Submitted by crookedvulture
crookedvulture (1866146) writes "AMD has revealed more details about the unified memory architecture of its next-generation Kaveri APU. The chip's CPU and GPU components will have a shared address space and will also share both physical and virtual memory. GPU compute applications should be able to share data between the processor's CPU cores and graphics ALUs, and the caches on those components will be fully coherent. This so-called heterogeneous uniform memory access, or hUMA, supports configurations with either DDR3 or GDDR5 memory. It's also based entirely in hardware and should work with any operating system. Kaveri is due later this year and will also have updated Steamroller CPU cores and a GPU based on the current Graphics Core Next architecture."

RyanDJ (1897546) writes "Ryan Johnson | GoozerNation

Nintendo's newest update has got to be one of the most sought-after updates in recent history. The update itself does little more than speed up some menus and a few other performance issues, but the next-day release of the Virtual Console is something many think Nintendo should have had ready Day 1. Even though 90% of Nintendo fanboys will agree with you that the Wii U has had a rocky start, Nintendo is pushing back strong. Here are four things Nintendo is doing right, and some issues they still need to pay attention to."

+ - Apple's smartphone share in single digits by Sept?

Submitted by ozmanjusri
ozmanjusri (601766) writes "Apple's share of the global smartphone market fell from 23% last year to 17% share this year, the largest year-over-year decline in the iPhone's history. According to Sanford Bernstein's Toni Sacconaghi, "if Apple does not introduce a new iPhone or lower-priced phone in CQ3 [Apple's fiscal Q4], it is quite possible that iPhone's smartphone market share could drop into the single digits."

So what can Apple do? The iPhone 5S fingerprint reader isn't likely to inspire excitement, and Apple needs something startling to regain the smartphone limelight. Do they have anything else up their sleeves?"

+ - Grocery delivery is greener than driving to the store->

Submitted by vinces99
vinces99 (2792707) writes "Those trips to the store can take a chunk out of your day and put more carbon dioxide into the atmosphere. But now University of Washington engineers have found that using a grocery delivery service can cut carbon dioxide emissions by at least half when compared with individual household trips to the store. Trucks filled to capacity that deliver to customers clustered in neighborhoods produced the most savings in carbon dioxide emissions, but there are even benefits with delivery to rural areas."

By that reasoning (source site is "biased") one might also say that we can't trust anything Microsoft says about their own product, either

You'll notice that my comparison did not to Microsoft (or it's fans) vs it's own products, it's Microsoft vs a competitor's product.

You can trust that Microsoft will paint their own products in the best light, but you can't trust what they have to say about Linux or OSX will be factual and accurate. The article I was referring to above was titled "125 reasons not to buy a Windows Phone 7.5" - the title alone should tell anyone with half a brain that it's unlikely to be objective.

Except the reality is Windows Phone [was] is not very good, [125 REASONS NOT TO BUY A WINDOWS PHONE 7.5

Referring us to the web site of a competitor's product to convince us that Windows mobile is not good is about as asinine as referring us to Microsoft's web site to prove that OSX is a bad operating system. They're not going to be impartial!

Even if isn't a site run by Nokia, it's going to be a site run by fanboys who are even less likely to be impartial.
