Expect the unexpected!
As per this report, twitter's monthly publicity is worth $48 Million. According to an analysis conducted by Video Monitoring Services (VMS), Twitter enjoyed 2.73 billion impressions last month, valued at $48 million.
"This is huge. It's very, very high," said Gary Getto, VP-integrated media intelligence at VMS. "In fact, we looked at online coverage of Twitter vs. Google. Twitter is running significantly higher than Google and I didn't think anything was more popular than Google."
In my view, healthy competition is always good and a reason not to worry about the elephant in the room.

I have been thinking for quite sometime that how much space do we really need to save our personal data, videos, pictures, etc…?
We have been seeing how discs, memory cards and personal drives are expanding their sizes day by day and nothing seem to be enough for consumers.
So, ever thought what is that magic limit we really goanna satisfy ourselves and stop worrying about the “need for space”? How about if I told you, you’ve got 100TB (TeraByte) of space! - will that be enough? I’m quite sure that 100TB is definitely going to quench your thirst for a “reasonable amount of time”.
Curious what the heck in the world can provide that kind of space? the technology is almost here and is called “HVD” – Holographic Versatile Disc
When you fill up 100TB, ever thought about the backup/restore time and the additional media you would need to keep your data safe?
Let me know your thoughts.

For those propeller heads who wants to know what a SLAT is, read on….
SLAT stands for “Second Level Address Translation”. SLAT is a new feature in today’s CPU on top of Virtualization support (Intel-V, AMD-V etc) to improve VM performance while reducing processing load on the hypervisor by removing the need for the hypervisor to maintain shadow page tables for each VM mapping virtual memory to physical memory.
So, ever thought about what happens when you move or migrate a VM from a host with SLAT support to another one without?
Answer is “Nothing”. You’ll obviously notice a slight performance degradation due to higher overhead on the receiving hosts’ hypervisor, but there won’t be any impact on its functionality.

Haven’t you heard about chimney which work as an exhaust in traditional Kitchens and factories?
Now one of the virtual networking features of Hyper-V in Windows Server 2008 R2 is using this word as “VM Chimney” - may be MS wants to emphasize that you got an easy path to flow. Anyway, VM Chimney in Hyper-V allows a VM to offload its network processing load onto the NIC of the host computer. This is something similar to TCP offload scenario, Hyper-V simply extends this functionality into the virtual world. This benefits both CPU and overall network throughput performance, and it is fully supported by Live Migration.
VM Chimney is disabled by default in Windows Server 2008 R2, primarily for compatibility reasons. Vendors like Intel, supports the compatibility for VM Chimney and if you are sure that the hardware you purchased support this – TURN IT ON for a better host system performance and a simultaneous boost to VM network throughput.
Support for Jumbo Frames was first introduced in initial release of Windows Server 2008 to support the hardware and now the same has been extended to support VMs. So, just like improving performance on hardware level, Jumbo Frame capability for VMs now can increase the performance of virtual networking and provides 6 times larger payloads per packet, which improves not only overall throughput but also reduces CPU utilization for large file transfers.

Sometimes nice and slow wins the race! Google introduced their own browser sometime ago and now they are here with their own OS – Chrome OS.
As per this blog, “We hear a lot from our users and their message is clear — computers need to get better. People want to get to their email instantly, without wasting time waiting for their computers to boot and browsers to start up.”
So, Google is behind redesigning the traditional OS behavior. Nice shot on Microsoft and others :-)
Initially the chrome OS will run on both x86 as well as ARM chips and later on notebooks by 2010. Like any other Google offerings, this will run on top of a Linux Kernel too. For developers, the web would be the platform and not the OS. The application will run on any OS as long as it is supported by a browser – Excellent approach Google!
As solid-state storage devices are getting bigger and better, it would be revolutionary if Google transforms this OS to run like a toggle switch from such devices.
Interesting to see how other platform owners will respond to this yet another “Google Idea”. Apple is already taking actions to force Google chief Eric Schmidt from their board.
