Few days ago Google changed their favicon, from “Big G” to “small g“. It was a surprise! Why would google change the “Big G” which is recognised all over the world!
Lots of questions filled my head…
• Why would google change the “Big G” which is recognised all over the world and create a dip in its brand recognition.
• Is this one of the google’s marketing trick to create buzz(as if they need one!)
• Is it trying to re-brand? (why would they do! everything is working more than fine for them)
No need to ponder more... I just "googled" it and found the answer on their own blog.

Laying chips vertically, instead of side by side, reduces the distance data has to travel by 1,000 times, making the chips faster and more efficient.
Big blue has said that it will start producing the compact silicon sandwiches in 2008.
Chip manufacturer Intel has previously announced that it is also developing similar vertical chip technology.
Last year, the firm unveiled a chip with 80 processing cores and capable of more than a trillion calculations per second (teraflops) that used vertical stacking technology.
Other firms, such as Tru-Si, have also developed techniques for creating 3D stacked chips.
Today most chips are laid out side-by-side, connected by wires.
The new technique involves placing chips directly on top of each other, connected by tungsten filled pipes, etched through the silicon.
These "through-silicon vias" (TSV), as they are known, eliminate the need for wires, increasing the speed at which information can flow between chips.
It has taken researchers at IBM a decade to refine the precise technique for mass producing the multi-storey chips.
"This allows us to move 3D chips from the 'lab to the fab' across a range of applications," said Lisa Su, vice president, semiconductor research and development center at IBM.
The first application will be in wireless communications chips. Using TSV will increase the efficiency of the chips by up to 40%, the firm says.
IBM is also exploring use of the technique in their multi-core chips.
As more and more cores are added to chips it becomes increasingly difficult to deliver uniform power to each one. By stacking them vertically and reducing the length of the connections between them, IBM hopes to overcome this problem,
Using these high-rise multi-core chips should also increase processor speeds and reduce power consumption.
Advantages like these also make 3D chips attractive for use in supercomputers.
IBM says it is developing the technology for use in the current fastest supercomputer in the world, Blue Gene/L.
The ultra powerful number cruncher, installed at the US Department of Energy's Lawrence Livermore National Laboratory (LLNL) is already capable of 280.6 trillions calculations per second.
The 3D stacked chips would allow a "new generation of supercomputers", IBM said.
The first chips will be available by the end of 2007 with full scale production expected to begin in 2008.

In previous versions of SharePoint (or other platforms), if you had some task you wanted to perform on a scheduled basis, you'd have to either create a console EXE and schedule it to run via Windows Task Scheduler (ala AT.EXE) or create a Windows Service that went to sleep for a period of time. In order to install (and maintain) these tasks, you had to have console access to your production SharePoint (or other app) servers... something IT or admins wouldn't easily hand out.Addressing this issue, Microsoft has added something called timer jobs to Microsoft Office SharePoint Server (MOSS) 2007. Microsoft uses timer jobs to do things like dead web cleanup (purging unused sites from site collections) among others. To see what other timer jobs are out there, from Central Administration, click Operations and then Timer Job Definitions. Not only does Microsoft use timer jobs in MOSS, but you can create your own custom timer jobs to do your own scheduled tasks. What's nice about this is once your timer job has been installed (something you can easily do with a solution & a feature), you can view it's status through Central Administration and even disable/enable it... all without console access to your production servers! Another cool thing is that when your job runs, MOSS passes it the GUID of the content database for the site the job is registered with. You can use this GUID to obtain a reference to a content database, then a site collection, and finally a site within the collection (SPWeb).
How do you build one? Well, unfortunately the documentation is lacking here... there isn't a single article in the SDK talking about creating custom timer jobs and the necessary objects aren't well documented either.
MVP Andrew Connel has described the Custom Timer Jobs on SharePoint well in depth on his blog http://www.andrewconnell.com/blog/articles/CreatingCustomSharePointTimerJobs.aspx. Awsome functionality. Thanks Andrew.
