Microbenchmark showing process-switching faster than thread-switching; what's wrong?
Category : Programming Languages

I have two simple microbenchmarks trying to measure thread- and process-switching overheads, but the process-switching overhead is turning out to be lower than that of thread-switching, which is unexpected. The setup: 1.8GHz Core 2 Duo, 2GB RAM, Linux 2.6.32-21-generic x86_64 (Ubuntu 10.04). I'm getting:


~2.1-2.4us per process switch
~4us per thread switch

I tried also run

I want to extend the Ctrl+Tab / Ctrl+Shift+Tab switching. so I wrote some code which works fine as long as the focus is on TabControl or on the Form.

Bank switching in PIC mcu
Category : Programming Languages

Usually I do a banksel before every GPR access but I find that I have many unecessary lines. So, the question is this. I do some calls to subroutines that access diferent memory banks than the calling routine. Is it a good idea to save in a GPR, the STATUS register, for maintaining the current bank and switch back to it before returning or what is the optimal way of doing this?

Category : Programming Languages

We have a private site for customers. Clients often tell us that they see profile of another user.


Our authentication procedure looks like this:
credentials -> check the DB table -> UserId saved in Session.


As I understand, the user somehow switches to another user's session. Can anyone name at least one possibility for it?

The basic settings under General > Restrictions let me turn off a few apps, but this is inadequate. Ideally, I need two provide t

iPhone app switching
Category : Mobile Programming

Is it possible to run an iPhone app from your own app?
For example when you press a button in your app, the iPhone switches to another app.
If so, how would you do this?
