If you are a SharePoint developer or administrator, then start learning Power Shell. It’s a must have skill for dealing with SharePoint from now on wards.

Windows Power Shell is an interactive command line and task based scripting technology which allows administrators to automate administrative tasks.

From SharePoint viewpoint, Power Shell has significant performance benefits:

Here is the Power Shell script to enable a feature on every SPSite:

$rawdata = stsadm.exe -o enumsites -url $WebAppURL   

$sitexml = [XML]$rawdata

$sitesxml.Sites | foreach-object{ $_.Site } | foreach-object{

  stsadm -o activatefeature -url $_.url -filename $featureFileName

         if( $lastexitcode -ne 0 ){ 

            Write-Host “Failure:$lastexitcode `n" -Fore Red;

            $failure = $true; 

         }

}

It will take 12+ hours for 5300 SharePoint sites. Whereas same code in Power Shell would be like following:

Get-SPSite –Limit ALL –WebApplication $WebAppNameorUrl |%{ 

   Enable-SPFeature $FeatureIdOrName –url $_.Url 

}

And this will take only 30 minutes for same 5300 sites :-)

So learn Power Shell and start rolling with all new 652 power shell cmdlets in SharePoint 2010 as compared to STSADM based 182 commands in SharePoint 2007.

If you are facing this dreadful 1335 problem with your Windows Server 2008 or VISTA operation system during installation, try following:

Start -> Run –> cmd

Then type in:

msiexec /unregister (press enter)
msiexec /regserver (press enter)

Now install that program again without firewall or virus programs turned on or running :-)

In its continuous effort to get the European Commission off its back, Microsoft has confirmed this week that it will be publishing the specifications of the .pst file format which is used to store Outlook data. Currently .pst files can only be accessed if Outlook is installed and that is just one of the interoperability issues the EC is concerned about.
By publishing the format's specs, Microsoft will enable customers and developers to access the data in .pst files on a variety of platforms.
According to Paul Lorimer, Group Manager, Microsoft Office Interoperability, the .pst documentation is "its early stages," but, once done, will be offered under the Open Specification Promise, which allows anyone to implement the file format on "any platform and in any tool, without concerns about patents, and without the need to contact Microsoft in any way." Viva la revolucion!

In this day an age it's not easy keeping up with what your friends are doing and between blogs, social sites and forums, you'll most likely miss something that would have been of interest. Trying to help you be friend informed without much hassle, Google has released via its Labs an experiment called Google Social Search.
Once activated, Social Search will personalize your search results so that, if there's relevant web content written by people in your social circle, it will be listed at the bottom of the result page under a section called "Results from people in your social circle." The social circle can include Gmail contacts and chat friends, people from groups you are part of, as well as individuals connected via social sites like Twitter and FriendFeed.
According to the Google Blog - "All the information that appears as part of Google Social Search is published publicly on the web - you can find it without Social Search if you really want to. What we've done is surface that content together in one single place to make your results more relevant."
For a bit more explaining on how Google Social Search works see this video below:
