Depending on what one wants to do with such a server, getting software stacks to run on it is important. For example, Oracle doesn't compile Java for PowerPC/Linux (no surprise there), one has to get the IBM J9 version. As long as one is using mostly Open Source software, it should be possible to build a version for PowerPC, but commercial software may be harder to find for PowerPC/Linux.
When people release new product lines based on PowerPC these days, it's news.
Personally, I'm glad to see PowerPC still going strong. IMO it's a much better instruction set than x86 or ARM. Now we just need a development board with Raspberry Pi pricing.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
