Data Visualization: Modern Approaches

December 26th, 2012

usData presentation can be beautiful, elegant and descriptive. There is a variety of conventional ways to visualize data – tables, histograms, pie charts and bar graphs are being used every day, in every project and on every possible occasion. However, to convey a message to your readers effectively, sometimes you need more than just a simple pie chart of your results. In fact, there are much better, profound, creative and absolutely fascinating ways to visualize data. Many of them might become ubiquitous in the next few years.

So what can we expect? Which innovative ideas are already being used? And what are the most creative approaches to present data in ways we’ve never thought before?


Let’s take a look at the most interesting modern approaches to data visualization as well as related articles, resources and tools.

 Digg BigSpy5 arranges popular stories at the top when people digg them. Bigger stories have more diggs.

Fixing nc8540p EliteBook: headphone jack problem in Windows 7

May 6th, 2011

This post is about how to fix sound problem in nc8540p EliteBook laptop with Windows 7 Pro (x64) . Just recently, I’ve had a problem with my headphone jacks. When I plug in my headphones, the sound still comes out of the laptop speakers, but no sound comes out of the headphones.
Doing some search in the internet I have got a solution (in my case it works) – IDT audio driver has to be installed instead Microsoft’s one.
1. Download IDT High-Definition (HD) Audio Driver from HP site here.

2. Install it and restart computer.
