Android vs Meego (more precisely Motorola Xoom vs Nokia N9)

Let me first address the fact that I work for such a company which is a leader in mobile devices. When it comes to mobile phone people still talk about them despite of so many rumors in the market and declining market share. But my post here today is not influenced by that fact anyway, neither I want to pretend something. I'm honestly writing my experience with these 2 devices and their OS'es from my extensive daily use.

I know comparing XOOM with N9 is just like comparing a Whale with a River Shark. Believe me I don't have another Android hand set of similar kind to compare. But I must tell you that despite of the price and HW spec that XOOM has, it still falling behind N9. Here it is how.

I had the opportunity to try N9 as a part of a Nokia internal program for testing. I'm using the device for almost 3 months now. Last Sunday I bought Motorola XOOM by spending almost 40K INR for my personal reason. But after using it almost for a week, I realized its not worth the price I paid for.

Build your own private cloud using Ubuntu Eucalyptus Enterprise Cloud computing platform.

1.0 Introduction

In this Hands-on Labs session, we’re going to use the Linux Ubuntu 10.04 LTS (Lucid Lynx) release. Ubuntu 10.04, Lucid Lynx, is the platform of choice for anybody who intends to build and deploy large-scale infrastructure, whether you're trying to build the next Facebook, or the next Google, or the next eBay. If you want to start on [Amazon's cloud-platform] EC2 and migrate to your own managed private cloud, Ubuntu 10.04 is going to be the platform for you. Lucid Lynx will be the third long-term support (LTS) release by Ubuntu. LTS releases arrive bi-annually and are supported for three years on desktops and five years for servers.

Microsoft walking to open source

Back in July, Microsoft announced it was making .NET available under its Community Promise, which in theory allowed free software developers to use the technology without fear of patent lawsuits. Not surprisingly, many free software geeks were unconvinced by the promise (after all, what's a promise compared to an actual open licence?), but now Microsoft has taken things to the next level by releasing the .NET Micro Framework under the Apache 2.0 licence. Yes, you read that correctly: a sizeable chunk of .NET is about to go open source.
