Every cloud has a silver lining - so it's a way of making money, you see.

But I see from wikipedia that "an empirically-based 1.5 sigma shift is introduced into the calculation". Aye, right.

Yeah, those numbers are due to the somewhat contentious 1.5 sigma shift.

[expat]

One Sigma = 690,000 DPMO* = 31% efficiency
Two Sigma = 308,000 DPMO = 69.2% efficiency
Three Sigma = 66,800 DPMO = 93.32% efficiency
Four Sigma = 6,210 DPMO = 99.379% efficiency
Five Sigma = 230 DPMO = 99.977% efficiency
Six Sigma = 3.4 DPMO = 99.9997% efficiency

In pure stats, that's not right: +- sigma on a normal distribution includes about 68% so is about 68% efficiency, or 32% "defective". ISTR that 2 sigma covers about 95% and 3 sigma very roughly 99.5%.

But I see from wikipedia that "an empirically-based 1.5 sigma shift is introduced into the calculation". Aye, right.

I'll have you know I'm a six-sigma greenbelt young man so less of the cheek!
But I think you're right. It was a long time ago & I never used it once.

I usually work to 2 sigma, the rest is Friday afternoon.

Can anyone award Xen geek points

No

and would it be proper for Xen to accept them?

N/A, but yes.

It was 99.9999% back in my day. Kids these days etc.

Six standard deviations, shurely?

I think Six Sigma is +3 and -3 standard deviations from the mean.

I have (of six sigma). It's a good system but generally mis-applied. It was designed for GE aerospace and nuclear to ensure reliability (where you really don't want to just slap it on and hope for the best), the six sigma relates to the percentile, so 99.9999 reliability is six sigma. I could tell you more but then I'd need paying and I'm not seeing anything on the table here.
Read that cloud article too, and though I hate to say it I agree with sasguru - just seems to be wi-fi, internet, data centre with a bit of virtualization thrown in.

No need. I can get 10 Bangalore black belts at the drop of a hat.

Cloud Computing is simply on demand compute power across the enterprise

These half assed dimwits just like to complicate things! It is still in its infancy as majority of hardware wouldnt know what on-demand is if it started pole dancing nekid infront of it
