Re: DBus signature for gtk objects

[Henrique Ser]

Hey,

Both slider-puzzle and jigsaw-puzzle do this when sharing a puzzle (or 
when using the Journal storage). It wasn't straightforward iirc, but 
feel free to dig in the code and ask if there is something cryptic there.

And it is slow, so be prepared...

 I want that for sharing Oficina (paint) activity through the mesh.
 When a user enters in a shared drawing, the owner would send his 
 pixmap for this new user.
 Maybe serializing the pixmap wouldn't be a bad idea, cause it's passed 
 once per user who join the activity and wouldn't let the activity slow 
 after loaded.
 If you have any other advice, please let me know.

 Thanks

 You cannot just use a remote object as if it was a gtk.gdk.Pixmap,
 they
 are just two very different pieces of code.

 My guess is that for doing this, you would need to get the Pixmap
 from
 the X server to the client side (Pixbuf), serialize it somehow,
 and pass
 it as a dbus.ByteArray or as a path to a temp file in disk (if that's
 possible in Rainbow). The other side would need to create a Pixbuf
 from
 it and send it to the server as a Pixmap.

 This process is not only convoluted, but will be also quite slow.

 Perhaps there is some way in X for two processes to share pixmaps,
 but I
 don't know about that.

 Why you want to do that? If you explain it, perhaps we'll be able to
 give better advice.

 Regards,

 Tomeu

Re: Increasing performance by tuning swappiness

[Henrique Ser]

I beg to differ. I have both a B2 and a B4, and running 500+ builds 
(currently 595) in the B4 goes as smoothly as expected, but the B2 just 
drags itself around. This was obviously primarily due to lack of memory, 
so I'm swapping off a 512MB external flash drive and it's still slower 
than the B4, obviously, but it works pretty fluidly, so there is a major 
difference in the B2 using swap, I can assure you of that.

 Actually, swap should have been a great solution for B2 machines with a 
 modern (i.e., 500) image. Theoretically, the additional swap memory 
 provided by an external usb2 storage device should allow a smoother 
 execution of memory hungry applications.
 In practice, the additional swap did not help, probably because the 
 memory watchdog does not take into an account the possible additional 
 swap. I'll check if changing the swappiness helps in this situation.

 Hi,

 Any thoughts on this subject?

 Yes:  we don't use swap.
