My Tech Rambling

I was mad trying to get registered with TPB for a long time and for some reasons, it didn't work even though the details provided were. While I was doing some experiment with IP anonymizer, I came across Change IP & Country ( cIPC) from http://anonymizer.nntime.com/ and I tried registering with TPB and it worked. I am not sure why TPB has blocked registration from my country.

I was quite frustrated that I could not install VSeWSSv12.exe - WSS 3.0 Visual Studio extensions 1.2 for VS 2008, because it requires having WSS 3.0 installed on the machine. I don't have a powerful computer to host a vpc / vm with Windows 2003, Visual Studio and WSS all the other required things to develop applications. I had to break - through the installation process somehow. So when executing the "VSeWSSv12.exe" downloaded from MS, it unpacks the MSI to a folder "C:\Program Files\MSECache\vsewssv12.en-us" and starts the MSI installer. While still the setup is executing, I copied that folder to another location. I had the ORCA, MSI Editor already installed. By Trial and error, I found that, by dropping WSSNotInstalled Action from CustomAction does the trick. Once the extensions are installed, Sharepoint Project types within VS 2008 will start appearing. Microsoft.Sharepoint.dll and any other sharepoint DLL's which would be reference within the projects w...

Recently I and my team started building so-called RIA kinda solutions and we are doing it using Adobe family of technologies Flash, Flex, ActionScripts, blazeds, weborb and etc. We are using Adobe Flex Builder as the IDE for developing the same. The debug feature for the Flex was working on few machines and in few machines it threw us an error as below. "Installed Adobe Flash Player is Not a Debugger" with a detailed message saying, Flex Builder cannot locate the required debug version of Adobe Flash Player. You may need to install the debug version of AdobeFlash Player 9.0 or reinstall Flex Builder. Do you want to try to debug with the current version?" Installing the Flash player from the link provided in the error message also did not help. I searched the internet for a while and could not file anything useful to fix this. This has become annoying and we found it was difficult without debugging. This is what I had done to fix it. Uninstall any Flash player from Add R...

Few open source grid computing softwares --- quite interesting Gridgain - Completely built on Java with the below key features Advanced Affinity Map/Reduce Annotation-based grid-enabling with AOP SPI-based integration and customization Advanced load balancing and scheduling Pluggable Fault-Tolerance One compute grid - many data grids Zero deployment model JMX-based Management & Monitoring   BOINC A software platform for volunteer computing and desktop grid computing.

Second CTP (Community Technology Preview) of Parallel Extension for .NET Framework 3.5 was released on June ( 2 nd ) . This enables utilizing of Parallel Hardware for application developed by .NET developers & improves performance as the numbers of cores and processors increases. With just a little bit of learning programmers can easily exploit the benefits of concurrent programming. Normally application would need parallelism for 2 things. a) Data Parallelism: Enables you to break problems into individual parallel units of work by partitioning data, like arrays, lists, loop iterations, or XML files. b) Task Parallelism: Provides more control over the expression of parallelism, enabling you to divide work based on the way your program's logic is grouped into functions and statements. Parallel Extensions for .NET 3.5 gives 2 flavors for Parallelism. Imperative parallelism : requires explicit calls to be made to begin and wait for work to finish. Declarative Parallelism: Hides ...

To BM I had shared a simple piece of code to have presence integration - term for linking office communicator to any normal windows or web application - for one of the applications in my orgn. I am not going to explain it all over here - if you want that please refer to BM's blog - rather tell you how i did it. Disclaimer : We had no chance to see that code works if you have Office / Live communicator 2007. It would be good if someone could test and share this to the community I had seen Presence integration on the Sharepoint pages ( If i remember correctly its the contacts webpart) . I was landing into Microsoft's presence integration samples and the ASP.NET examples were not quite interesting and looked like a lot of plumbing. I abandoned that idea and started looking at the HTML (view source) of the sharepoint pages and understood, which javascript piece is required, what ActiveX control is used...etc... If i am not wrong its all the functions and variables that starts wit...

How I screwed things on my own... Recently I was supposed add new disks of 3 TBs ( 5 Physical 750GB disks) to an existing Linux LVM. A new big disk of 3TB was created from the array of disks. Used "parted" to create a big partition for the whole disk size( normal partitions bigger than 2TB are not supported via fdisk) and went ahead adding the new disk space to LVM. things went fine , when i finally checked with lvmdisplay the new size was increased in the target lvm.... but , vgdisplay and pvdisplay didn't report it appropriately :-( No issues, since i remembered the previous size, i shirked it using lvextend -L -3TB. then any command that i issued was throwing error. and things got screwed. Goggled a lot to get a resolution and didn't land to any right spot. then browsed through all the commands that get installed with the lvm RPM. then found 2 important commands vgcfgbackup and vgcfgrestore. What I learnt. the /etc/lvm folder is quite important. backup, cache, ...
