Scientists at IBM speculate that the world’s most powerful supercomputer processors could shrink to the size of a sugar cube. They see many computer processors stacked on top of one another, cooling them with water flowing between each one. The plan is to reduce computers’ energy use, rather than just to shrink them. Most of the computer’s energy costs is in cooling, because computing power generates so much heat as a side product. Dr Bruno Michel and his colleagues have already built a prototype to demonstrate the water-cooling principle. Called Aquasar, it occupies a rack larger than a refrigerator.
In the past, computers were dominated by hardware costs. Future computer costs will hinge on green credentials rather than speed.”
"One of the most recurrent themes is that of open-source vs. proprietary code. This debate is often painted with the idealistic open-source evangelists on one side, and the business-focused proprietary software advocates on the other. This is, of course, an unfair depiction of the topic. In reality, when debating open-source vs. proprietary, several issues tend to get conflated into one argument – open-source vs. closed-source, free vs. paid-for, restrictive vs flexible licensing, supported vs. unsupported, code quality, and so on."
