light3··on Equation: How Much Money Do Spammers Rake In?
0.238 * 0.000127 * 100 * 1700000 * 550 * 0.093 * 0.266 = 7000

So they assume 90.7% of messages get caught by spam filters.

Apparently they send out around 1 billion emails, 23.8% of which gets delivered. Around 2600 people read the emails, and a quarter of them will an average of $100.

light3··on Larry Page Wants to Return Google to Its Startup Roots
"One way Page tries to keep his finger on Google’s pulse is his insistence on signing off on every new hire—so far he’s vetted well over 30,000"

Wow that works out to be 9 everyday for the past 10 years, really?!?

light3··on I'll take "Sticking it to United" for $49
Isn't he dismissing the risk that the airline won't be able to sell the ticket within the next 48 hours? The potential for the airline to make $400 is there, but the expected revenue is below that.
light3··on Video of tsunami in Japan
I like how the water level rises from the beginning to the end, at the start there's just a few cars moving a little and you're like "this isn't so bad", and then at the end water is gushing in with cars and buildings rolling around in a cacophony of madness, even the camera man has retreated to well above water level at this point.

They can be shaped as coins and become a new currency, it glows green when fully charged. Devices(including cars) have coin slots to take in power.

"It's the volatility that determines the prices"

I thought this is only the case with contracts where the payoff is not linear, i.e. limiting the upside or downside. Future contract payoffs are linear f(t) = S(T) − K, so the upside is the same as the downside.

light3··on Cringley: Japan may have just permanently lost 20% of its electricity supply
I guess the obvious question is whether 80% of electricity supply meets demand, probably not, how can Japan generate the additional 20% in a hurry?

I believe oil sold on futures markets are in barrels and not tankers.
light3··on The Way You Learned Math Is So Old School
Surely that method of multiplication is not suited for larger numbers, to get 246 * 369 u do 200 * 300 200 * 60 200 * 9 40 * 300 40 * 60 40 * 9 6 * 300 6 * 60 6 * 9 So for x-digit multiplied by y-digit u need to write down x*y products and then sum it up, where as for the old method you need to only write down min(x,y) products and sum it up.

Imagine how thin and light it could be if batteries were not required.
light3··on Why Gas Is So Expensive Today (Hint: It’s Not Libya)
There is definitely a correlation, at least recently, between availability of credit and the increase in commodity prices.

One way to explain this is to look at house prices, and how real-estate agents 'value' these. They will value a property based on the past value of this property, the general increase in price levels since the last sell, and the price of recently sold properties in the area. Properties are not homogeneous, however the 'value' of all properties in a given area will be affected by the price changes of those being bought/sold.

"because none of the banks sell what they hold, the price goes up; because the price goes up, more people make money on their positions; because they make more money on their positions they buy more stuff and don’t sell what they hold; and on and on forever"

That is until the bubble pops, those who got in late and can't sell will make a loss. The bid-ask spread widens, in particular there is glut of people wanting to sell at high prices, whilst there are few cautious buyers willing to offer lower prices.

light3··on Support The Victims of Japan's Earthquake With Your Loose Change
I wonder where all the money will go to, and whether a developed country like Japan really need help to handle the disaster in this situation, given their history with such events.

Its really hard to find where the money will go to, the swipegood site doesn't even link to world vision, I had to get there through google. The world vision site says:

"Your gift will help us rush emergency supplies like life-saving food, clean water, medical supplies, and shelter to survivors."

Your gift will help World Vision respond to this and other disasters around the world including:

A devastating drought and food crisis is threatening more than 7 million lives in the Horn of Africa. Increasing numbers of children are severely malnourished and at risk of disease in Kenya, Ethiopia, and Somalia. Millions of displaced children and families are struggling to survive in Sudan after decades of civil unrest. The recent Referendum has brought hope for peace, but malnutrition, disease, and poverty remain at critical levels. Heavy monsoon rains have caused widespread flooding in Sri Lanka, displacing more than 200,000 people from their homes and impacting 1.2 million. World Vision is continuing to support earthquake survivors in Haiti, rebuilding their communities and meeting essential needs for food, clean water, and healthcare. World Vision urgently needs your support to help children and families suffering from these and other disasters around the world.

So by donating here you're implicitly donating to other disasters too.

light3··on How rich kids already won the career game
Probably has something to do with the huge trade deficit of the US, if the US was a large net exporter that created many jobs, people's opinions should be different.
light3··on Everything You Know About Fitness is a Lie
Very true, in my mother's generation overweight people in China were seen as 'freaks', as in circus freaks. This was even when there was enough food to feed everybody, most people remained in shape because

1. The food was whole. 2. People were very active, particularly where my mother grew up(Shanghai), mothers usually got up at 5am to get the fresh produce from markets everyday, people walked around a lot, bicycles were a luxury item.

light3··on Everything You Know About Fitness is a Lie
You're probably right, I was quoting from the overcompensation graph, the other chart actually says 8 sessions/week for endurance.
light3··on Everything You Know About Fitness is a Lie
Further, you should eat well and wait for your muscles to recover, the optimal time to retrain is during 'overcompensation', 40-60 hours for endurance and 48-72 hours for power, strength and mass.

As well, you should exercise 'weak muscles' to avoid injury, for people sitting in front of computers a lot it really helps to exercise the back muscles.

light3··on The Colour Clock
I'm on a P4 3Ghz at the moment, whereby I can hear my CPU buzzing away when its under load. On the .co.uk site the buzzing is audible, its taking >70% of the CPU, whereas on your site its nice and quiet taking just 6% of the CPU.
light3··on What I Wish Someone Had Told Me About Startups 4 Years Ago
Is there some hidden meaning to '20 years ago', am I missing something?
light3··on What I Wish Someone Had Told Me About Startups 4 Years Ago
Reminds me of my favorite violinist, his one of the cleanest players you'll find: http://www.youtube.com/watch?v=mixnMzHUYxA

Once he was asked what music piece he thought was most difficult to play, his reply was something like: "Either you can play a piece or you can't, there is no difficult, difficult leads to friction in your playing"

The 'not best' players when faced with difficult passages will consciously or subconsciously have fear of it and stress out, this is will cause tension and can be picked up by the viewer.

Milstein's was known for taking any musical piece he liked and 'hacking' it till he knew it inside out, for every passage he will try all sorts of fingerings. An average player will be content to play one fingering well, relying mostly on muscle memory, but Milstein would study a piece and really play from his head, at each moment he could choose between different fingerings. Thats how he thought and practiced, and if you look at his performance he is always relaxed because his preparation is so thorough and he played from his mind.

light3··on Visualization: Movies Are Getting Worse
Watching old movies like Star wars, Indiana Jones, old Bond movies, you get the sense that a lot of work was put in to creating the scenes. It must have been very expensive to make, was it because revenue was very high back then?
light3··on Visualization: Movies Are Getting Worse
> The Social Network - Sort of knew the story and acting was pretty ordinary.

> Inception - Cool story and nice effects, very captivating movie, made me think a little bit, but the ideas of the movie are too far fetched.

> True Grit - I didn't see the original, couldn't work out whether it was fiction until near the middle, and then it just went downhill, for me the girl did the best acting.

Worth watching? Definitely, become classics? Probably not, they're all missing the extra magic sauce.

Any examples of successful startups in Australia?
light3··on "You've angered the hive"
From http://www.thetechherald.com/article.php/201106/6785

"There was a distinction made that HBGary only owns 15-percent of HBGary Federal, and that attacking both was wrong, as one had nothing to do with the other. The networks shared many common elements, that they are only moderately related was irrelevant to Anonymous."

"In addition, there were several calls for Barr to be burned by HBGary, but given that he is a partner, that is unlikely. At this stage, HBGary’s response is unknown. At the time this article was written, aside from the conversations on IRC, there has been no official comment."
