  - by perimosocordiae

  Is it possible to store a type name as a C++ variable? For example, like this: type my_type = int; // or string, or Foo, or any other type void* data = ...; my_type* a = (my_type*) data; I know that 99.9% of the time there's a better way to do what you want without resorting to casting void pointers, but I'm curious if C++ allows this sort of thing.

• Sharepoint Web performance optimization

  - by hertzel

  We are running on SSL on following server topology: 1 ISA (SSL Terminate/cache/proxy+AD authentication) 1 Sharepoint 1 IBM DB2 Database as enterprise/corporate DB 1 MS SQL Server as local DB We have recently optimized the caching, compression, minification, and other ASP.net best practices such as viewstate and cookie sizes, minimizing round trips, parallel connections/domain sharding and a lot more.... Now we are not convinced that the we are in an optimized position as the network resources i.e. bandwidth and especially latency are out of our control!! The client/browser to server/sharepoint is trans-Atlantic i.e. (ASIA, USA, EUROPE). As of my understanding the only ways to improve the network (latency) are: - TCP/SSL optimization - hardware/software? - CDNs - cloud or our own ? Your opinion and insights would be much appreciated Best regards Hertzel

  In c it would be: while(1){ i++; printf("%d \r",i); } I assume the textview and the variable and the timer get created in oncreate, then there is a timer handler with an increment and a settext and a sleep? Seeing how to do this in androidese would really clarify things I think. Thanks.

• Sharing data between two instances in a load balanced java web application

  - by rabbit

  I want to cache data in a java web application deployed on multiple instances. We are using spring 2.5.6. What is the easiest caching library to configure and use with spring? I have heard of EH Cache, but the configuration is too cumbersome. The requirement is that a spring scheduler will run and set some flags. These flags are accessible from all load balanced instances. But since the scheduler runs only on one instance the flag is set only on that jvm. So how do i make these updated flag values available to all load balanced instances?
