The Newly Released Linux Kernel 4.20

Get High with The Newly Released Linux Kernel 4.20 – It’s FOSS article at https://itsfoss.com/kernel-4-20-release/ tells that Linus Torvalds played Santa and released Kernel 4.20 just before Christmas. Torvalds sees no point in delaying the 4.20 release because everybody is already taking a break. If you are a regular/average Linux user, you should not try

Amoeba finds approximate solutions to NP-hard problem in linear time

https://phys.org/news/2018-12-amoeba-approximate-solutions-np-hard-problem.html This is intresting finding that Researchers have demonstrated that an amoeba (a single-celled organism) has unique computing abilities. The researchers found that an amoeba can find reasonable (nearly optimal) solutions to the TSP in an amount of time that grows only linearly as the number of cities increases. Traveling Salesman Problem (TSP) is an

Truth is the First Casualty of Global Warming by Bjørn Lomborg – Project Syndicate

https://www.project-syndicate.org/commentary/climate-change-self-defeating-alarmism-by-bjorn-lomborg-2018-12 The truth about climate change is nuanced: it is real, and in the long term it will be a problem, but its impact is less than we might believe. And yet we are too eager to believe the problem is far worse than science shows. Climate change seems to freeze our capacity for critical

Step adjustable resistor box

A decade box is a type of test equipment that can be used to substitute the interchanging of different values of certain passive components when you need adjustable value in electronics laboratory. Decade boxes are made for resistance, capacitance, and inductance. Decade boxes are typically quite expensive devices (compared to other cheap electronics parts). I
