http://www.iflscience.com/health-and-medicine/scientists-may-have-found-the-root-cause-of-autism/  Scientists think they’ve found out what could be at the root of autism and, no, it’s not vaccines. According to a new study, it could be caused by having too many brain connections called synapses. “An increased number of synapses creates miscommunication among neurons in the developing brain that correlates with impairments in learning, although we →

https://blog.arduino.cc/2017/11/03/linux-support-comes-to-arduino-create/ This looks interesting:  update to the Arduino Create web platform will enable development and deployment of IoT applications with integrated cloud services on Linux-based devices.  Users will be able to program their Linux boards as if they were regular Arduinos. Multiple Arduino programs can run simultaneously on a Linux board and programs can communicate →

https://spectrum.ieee.org/nanoclast/semiconductors/optoelectronics/new-laser-technique-promises-photonic-devices-inside-of-silicon When a laser beam modifies a material, those modifications can either be temporary or permanent, and the change can also be either extremely subtle or drastic. The modified material starts responding differently to the laser beam. Scientists have taken advantage of these interactions to create structures within silicon that enable photonic devices. “We can also imagine →

https://boingboing.net/2017/10/31/perl-is-the-most-hated-program.html Perl, the Old Spice of programming languages, is the most disliked by a significant margin, reports Stack Overflow. Delphi, and Visual Basic are running neck-and-neck for second place. I think Perl is OK. I quess that most of those who hate it have never really tried it. There are many much worse programming languages that are →

https://m.slashdot.org/story/333069 The Internet Task Engineering Group (IETF) has approved the new HTTP status code 103.  The 103 (Early Hints) informational status code indicates to the client that the server is likely to send a final response with the header fields included in the informational response.  →

https://www.hackster.io/mhanuel/industrial-iot-gateway-based-on-android-things-c680d1 This project is a proof of concept of an Industrial Gateway based on Android Things.  Android Things allow to cut development time of the gateway by facilitating the integration with required interfaces such as Ethernet, UART, SPI and I2C. Android Things can be used in common SBC such as Raspberry Pi to have a quick →

https://m.dpreview.com/news/2842585992/researchers-teach-algorithm-about-textures-to-create-high-res-versions-of-low-res-images Upsampling image and video files usually leads to pixelation and soft textures, simply because algorithms are not capable of replacing non-existing image detail. But scientists at the Max-Planck Institute for Intelligent Systems in Germany have come up with a clever solution that is capable of producing better results than anything we’ve seen so far. →

The Valve Wizard web page is about tube amplifiers. They have a very good document on grounding issues in tube circuits. So read their 16 page Grounding document to learn about grounding (both general information and tube amplifier specific information).   →
