Carbon footprint labeling: Are you ready for it?
Pending regulations in Europe for a carbon footprint label on every product means that it's not enough to inform consumers your electronics product's power consumption level. You need to tell them the quantity (in grams) of carbon-dioxide emissions associated with manufacturing, transporting and recycling of your product.
Seven hard lessons on writing a grant proposal
What I learned in my ten-day marathon applying for an economic stimulus grant for smart grid training.
Enable greener data centers with SFP+ Direct Attach Copper
Given a move towards energy efficient data centers and higher bandwidth applications, small form factor, low power, low latency and low cost interconnects are more critical. Here's a case for SFP+ Direct Attach as an optimal solution for short reach 10 G interconnects.
