He's not telling you what to do with your code.
From the same interview:
"Some people love the BSD license. Some people love the proprietary licenses. I understand that. If you want to make a program and you want to feed your kids, it makes a lot of sense to have a proprietary license and sell binaries. I think it makes less sense today, but I really understand the argument. I don't want to judge. I'm just giving my view on licensing."
Submission + - SPAM: China homegrown electronic and world's fastest supercomputer 1
Taco Cowboy writes: Clocked in at 93 Petaflop (or 93,000 trillion calculations per second), the new ShenWei (roughly translates to The Wrath of God in Mandarin) TaihuLight tops the world's fastest supercomputer list
Twice as fast and three times as efficient as the previous leader Tianhe-2, the new ShenWei Installed at the National Supercomputing Centre in Wuxi and comprised of 10.5 million locally-made processing cores grouped into 40,960 nodes (with each node having 260 processor cores) the computer runs on the Linux Operating System
The processor is divided into four core groups, each with 64 computing processing elements (CPE) and a management processing element (MPE). Each core group also includes a memory controller delivering an aggregate memory bandwidth of 136.5 GB/second on each socket. It runs at a relatively modest 1.45 GHz and supports just a single execution thread per core
The chip was manufactured at the National High Performance Integrated Circuit Design Center, in Shanghai. The process technology node has not been revealed
Memory-wise, each node contains 32 GB, adding up to a little over 1.3 PB for the whole machine
Its main applications include advanced manufacturing, weather forecasting and big data analytics, wrote Jack Dongarra in a paper about the new machine ( [spam URL stripped]... )
Pierre Ferragu, tech analyst at Bernstein, said the ranking showed that China was “pulling together all the building blocks of an independent semiconductor value chain”
The system is also rather light on cache. In fact, it really doesn’t have any in the L1-L2-L3 sense. Each core is allocated 12 KB of instruction cache, along with 64 KB of local scratchpad
From a power standpoint though, TaihuLight is quite good. It draws 15.3 megawatts (MW) running Linpack, which, somewhat surprisingly, is less power than its 33-petaflop cousin, Tianhe-2, which uses 17.8 MW. TaihuLight’s energy-efficiency of 6 gigaflops/watt is excellent, which will certainly earn it a place in the upper reaches of the Green500 list
The interconnect, simply known as the Sunway Network, is also a homegrown affair. It’s noteworthy that the older Sunlight BlueLight machine employed QDR InfiniBand for the system network. The TaihuLight one, however, is based on PCIe 3.0 technology, and provides 16 GB/second of node-to-node peak bandwidth, with a latency of around 1 microsecond
Running MPI communications over it slows that down to about 12 GB/second. Such performance is pretty much on par with EDR InfiniBand or even 100G Ethernet, although the latency seems a tad high (it depends on exactly what’s being measured, of course). In any case, it looks like the design team opted for simplicity here, rather than breakneck speeds using exotic technology
“The latest list marks the first time since the inception of the TOP500 that the US is not home to the largest number of systems,” wrote the authors of the ranking. “With a surge in industrial and research installations registered over the last few years, China leads with 167 systems and the US is second with 165”

Submission + - PowerVR Wizard GPU does real-time ray tracing on low power PCIe card (imgtec.com)
alexvoica writes: During GDC 2014, Imagination introduced PowerVR Wizard, a new and scalable GPU architecture capable of running high-performance, real-time ray tracing applications in a tiny power budget.
Now Imagination is showing this new GPU working at full speed on a 28nm chip integrated on a PCIe evaluation board.
The PowerVR GR6500 is a mobile GPU that integrates fixed-function hardware for ray tracing workloads. Its die size, GFLOPS performance, bandwidth requirements and power consumption mean that it is comparable to the GPUs already available in smart phones today. But compared with a console GPU or looking towards the smart phones and handheld devices of the future, the Wizard architecture scales in capabilities and performance to more powerful cores.
To demonstrate this scalability, Imagination is showing several of the GR6500 boards working inside the same system. This configuration offers a proof point for high throughput ray tracing, in excess of a billion rays per second.

PC Pro has examined the effects of exposing children to technology at a young age. Researchers warn of the potential dangers of too much “screen time”, pointing to alarming (some say scaremongering) research that suggests over-exposure leads to an increased risk of developing autism and Attention Deficit Hyperactivity Disorder (ADHD).
Educators, meanwhile, highlight how technology can improve interaction between child and parent, and provide essential life skills, such as enhanced communication and multitasking. Parents are left with conflicting messages — but how much technology is too much technology for children?"
