I am a newby in GAE and I want to get involved on almost everything, so this is the next step.
You can have a look at: http://googleappengine.blogspot.com/2011/01/announcing-high-replication-datastore.html
The High Replication Datastore provides the highest level of
availability for your reads and writes, at the cost of increased
latency for writes and changes in consistency guarantees in the API.
The High Replication Datastore increases the number of data centers
that maintain replicas of your data by using the Paxos algorithm to
synchronize that data across datacenters in real time. One of the most
significant benefits is that all functionality of your application
will remain fully available during planned maintenance periods, as
well as during most unplanned infrastructure issues.
Hope this helps.

Can someone guide me on how to implement my own FIFO application to use is in IPC, I know that I can do this with SHM, socket or using any other sys-v or posix ipc.
The reason I'm looking for this is because I wanna build this fifo with my own specification that will suite my applications with the locking inside this application, so that any application can only call enqueue or dequeue, just like with fifo the kernel will make sure that it's atomic as long as you are writing less than the pipe_buff. I know how to build circular buffer queue but I'm not sure how will I call it from another application, do I need to build an API for it ? or is it something else?
the system is Linux and the language is c.
I would strongly recommend using POSIX MQ library. They are thread safe and I believe may be persistent. I've used it with a lot of success and it allowed me to focus on solving the problem at hand instead of rolling my own.

I am working on my minor project. I have to create an image editor in C. For that I want to handle mouse. As I know there are two approaches to handle mouse viz REQUEST MODE and EVENT MODE.
Over the past few days I have learnt Request mode but I'm having difficulty in performing a couple of things with request mode, so I decided to learn second approach i e Event mode. But unfortunately I can't find proper resources. It would be very nice of you if you can get me some examples and explanation of event mode approach.
look at this site

I have seen that related question but it didn't helped. I have a simple silverlight mvvm application for which I have created custom views and viewmodels and I have set the main view as rootlayout. Compiles succesfully, but when I hit run, the app hangs at 100%. I have placed breakpoints all over the app (in the views and in the app.cs) but it never reaches them. I'ved also replaced the mainview with a simple page with only a simple button on it (and set it as rootlayout), but still it hangs at 100% (I'ved thought that my view caused the problem, but it doesn't work on simple pages as well).
Is there any way to view the exceptions? Or something that I am missing...??
Silverlight version 3.
Thanks in advance

I am looking for fastest free key-value pair database available. Database doesn't have to be server-based, it can be linked into the application. I am aware of Tokyo Cabinet. Any other suggestions?
i vote for BerkeleyDB!
I don't know about fastest, but you can look at this question: Document databases/Key-value stores for use with .Net projects.
The reality, is that you will probably need to clearly establish a performance baseline and profile different databases for yourself to determine which will have acceptable performance for your specific application.
