https://www.edn.com/electronics-blogs/benchtalk/4460355/In-praise-of-the-common-base–Bench-quickie The common-base configuration is so little used, it doesn’t even register on many engineers’ radar. It is hard tp really learn and internalize a circuit until I have a need for it, and have done at least some small hands-on activity with it. This article describes how to test this type of circuit. →
This posting is here to collect security alert news in March 2018. I post links to security vulnerability news to comments of this article. →
https://spectrum.ieee.org/tech-talk/telecom/wireless/teaching-an-artificial-intelligence-to-operate-a-telecommunications-network-isnt-possibleyet AI, which telecos have already leveraged in some situations, might be able to help solve some of communications service providers’ (CSPs) problems. But CSPs have been slow to adopt artificial intelligence, because the initial problems AI was developed to address didn’t really affect them. “There’s a lot of opportunity to use AI in the →
https://spectrum.ieee.org/telecom/internet/5g-is-in-danger-of-being-oversold It seems that 5G has become a technology savior. Proponents tout the poorly defined wireless technology as the path to virtual reality, telemedicine, and self-driving cars. But 5G is a buzzword unleashed by marketing departments. In reality, 5G is a term that telecommunications investors and executives sling around. Millimeter-wave spectrum is freely available for →

You don’t need to be an experienced programmer to use SQL to create a database. This article explains how to create a simple relational database management system (RDMS) using MySQL 5.6. →
https://techcrunch.com/2018/02/23/google-publicly-launches-arcore-1-0-on-13-phones-will-begin-expanding-lens-availability/ With ARCore’s launch, developers are now able to put their own augmented reality (AR) creations into the Play Store and users able to take a first shot at phone. Just a small subset of all of the Android phones out there today. Google has already been working with companies like Snap, Sony, Wayfare, Porsche →
EEJournal reports that Microchip’s new SAMA5D27 is almost a postage stamp that runs Linux. It is a fully realized microcontroller module that measures about 40mm on a side. It costs about $39 in small quantities. I wrote about this board in Finnish to Uusiteknogia.fi magazine. →
Last year I made a posting on Cheap fiber optic visual fault locator. It told about 1mW 5KM Red Light Pen Visual Fault Locator Fiber Optic Laser Cable Tester Meter puts out highly visible red light into a fiber optic cable that has ST, SC and FC optical connectors.The universal fiber connector worked well with single-mode →
https://thenextweb.com/contributors/2018/02/21/batteries-holding-tech-breakthroughs-whats-happening-now/ Despite incremental advancements, batteries haven’t changed all that much over the past decade. Major brands are investing in better environmental efficiency, and small tweaks that improve storage and performance, but the typical “battery” is still fundamentally the same. There is stagnation in the realm of batteries. →
