That's it - no more Mac

Today, my Mac failed to back up via Time Machine. I thought the issue was with my external hard-drive... but it was not. My Mac does not recognize firewire or usb external devices anymore...
I have had enough, 2 batteries, one screen, no usb/firewire, a new screen that flickers...

I have backed up my 16 gig photos (since 2000) via Wifi.. to my old PC running Vista... this task took 3 h over wifi!

That and the fact that one need to upgrade to a 64bits Mac to have Java 6... no way.

Next laptop: a cheap one, running Ubuntu, plus Picassa.. and that's it - NO ITUNES. I'll wait for a music service from Google, OS-independent.

That's Apple, you've lost me as a customer.

Java RMI vs. RV

Well, the winner is Java RMI.
I performed a test to compare a RV C++ program (3 servers sending market data, processing it, republishing it) to a similar Java program using RMI for communication instead of RV.
RMI is 15 times faster than RV, achieving 200 micros between the market depth update and the price republished!
