A positive attitude will help you edge out cynicism and pessimism to restore hope and optimism.

“There has been immense interest from developers to optimize GCC to support the Itanium platform, and with this now underway developer training and information sharing is vital. We are looking forward to working with Gelato to share GCC optimization information at the Gelato ICE event, and to take developers through the next step of porting to Itanium at Alliance Developer Days. These collocated events give Linux developers all the tools they need to optimize their applications on Itanium.”
