https://www.tomsguide.com/us/apps-selling-location,news-28798.html Back in October, Tom’s Guide reportedthat it’s possible for cheap mobile advertisements to spy on you through your phone. Sales of location-targeted advertising reached an estimated $21 billion this year. This morning, a report from the New York Times warns that smartphone apps do that also for profit: More than 1,000 popular apps contain →
https://www.nature.com/articles/d41586-018-07448-0 Technological advances are transforming what researchers can study at the atomic scale. Using an ultra-sensitive detector that the researchers had created and a special method for reconstructing the data, they resolved features in MoS2 down to 0.39 angstroms, two and a half times better than a conventional electron microscope would achieve. The advanced transmission →
https://techcrunch.com/2018/12/02/bright-spots-in-the-vr-market/ Virtual reality is in a public relations slump. Two years ago the public’s expectations for virtual reality’s potential was at its peak. But still today the holistic VR experience is still a non-starter for most people. Can we extrapolate beyond the current state of affairs to a magnificent future where the utility of virtual →

https://techcrunch.com/2018/12/01/the-battle-over-the-driving-experience-is-heating-up-and-will-be-won-in-software/ We’re already seeing many new cars with driver-assist features. Many companies are working hard to bring fully autonomous cars to the market quicly. According to the Brookings Institute, one-quarter of all cars will be autonomous by 2040, and IHS predicts all cars will be autonomous after 2050. Those are conservative estimates. These changes will →
https://spectrum.ieee.org/computing/hardware/to-crack-the-toughest-optimization-problems-just-add-lasers Optimization is very important but is usually computationally very hard. Optimization encompasses far more than the traveling salesman problem. Scheduling is another difficult optimization challenge. Given the fact that the era of steady, large improvements in computer-processor performance appears to be coming to a close, researchers have begun to explore machines specially designed for →
I did earlier a teardown of broken Behringer B208D active PA speaker. Now it was time to get ot fixed. The problem was that sound level before distortion was very low and bass was missing. It seems that low frequency driver could output only 1-2V signal to speaker before distortion, and to get that the →
I wrote around two years ago a blog posting on RJ-45 Ethernet surge protection. Now it is time to check out what is inside one cheap Ethernet surge protector. The product here is very cheap (around $2) CY UT-013 Lightning Protection RJ45 UTP STP CAT6 CAT5e Female to Female Network Lan Adapter Extender. The specifications →
https://blog.hackster.io/picking-the-right-arduino-341a0a9550c7 Arduino started with just few boards, but now ten years later, there is an Arduino board type for (practically) every application or project. The choice can be overwhelming when selecting. This article gives overview if what to consider and what is available. Many of the latest boards are aimed fot IoT applications. →
