Data Mining Survey Results :Tools and Offshoring

Here are some survey results from  Rexer Analytics–

The Graphics seem self explanatory: terrific Data Visualization

1) The field of Data Mining seems ripe for either more offshoring to cut down costs or

there will be price pressures to cut costs on software ( read More R and SaaS) and Hardware ( more cloud /time sharing  ?)

2) Satisfaction with both R and SAS seems similar but R seems to score higher than other flavors.

3) An added dimension of  utility ( or say

(satisfaction in terms of analyst comfort + functionality in terms of business benefit) divided by (License + Training + Installation + Transition costs)

would have even extra analysis.

But these are not final results- for that you need to see Dr Karl at Rexer Analytics

Using Ipod and Iphone with your Ubuntu Laptop

If you love your  Apple iPhone / iPod, the latest release of Ubuntu from Canonical called Karmic Koala ( the counter part to Microsoft’s Windows 7) is totally compatible for USB connection

If you love your  Apple iPhone / iPod, the latest release of Ubuntu from Canonical called Karmic Koala ( the counter part to Microsoft’s Windows 7) is totally compatible for USB connection.

Ubuntu uses Rhythmbox for playing songs and uses FSpot and Gimp for images. The audio quality is excellent ( even if you are using very old hardware like I do) and Gimp is the best image manipulation software -comparable to ones from Adobe- intuitive and easy.

Holiday Season Offer

Here is a great offer from the Predictive Analytics Conference. Basically a 15 % discount to visit PAWS in San Fransisco AND a chance to win a free pass as well.

pawsf10_bp_125

discount code for the SF 2010 show: AJAY010
It gives your readers a discount of 15% off a Two Day Conference Pass (workshops not included). For every three people who register using your code, we will give you a free pass to the conference.

Since I basically need just one pass for the conference- if I cross more than 1 free pass, I will simply give it back to the people who registered using my blog. Simple.

However if this had been NFL tickets the offer may not be repeated again  🙂 ( note to myself- I need to get into predictive analytics  for sports using the data mining and analytics softwares I have been reading or find a company that has a predictive analytics for SPORTS vertical).
