Converting traditional sysV init scripts to systemd There is trend with many Linux distributions that old well known init system is replaced with systemd. It very different system that uses different techniques and scripts. This article gives tips how to convert a SysV init script to a systemd unit file.  It is useful to know how to use both systems, because everything will not

Building Services with BLE Beacons – Solinor Bluetooth low energy (BLE) beacons are small, typically battery powered, devices that periodically broadcast an identifier to their surroundings. They are an inexpensive way to make applications aware of their surroundings. With beacons no user action is required for an application to obtain the proximity information. When a smartphone enters the range of a beacon,

Zinc Battery Breakthrough Could Mean Safer, Lighter Cars and Smartphones – IEEE Spectrum Rechargeable zinc-based batteries could not only store as much energy as lithium-ion batteries but also be safer, cheaper, smaller and lighter, new research finds. The results suggest zinc batteries could find use in mild hybrids (microhybrids), electric vehicles, electric bicycles, and eventually perhaps smartphones and power grid storage. The researchers are now aggressively testing these batteries and exploring scaling

Finland’s depression Finland has lost a quarter of its industry since 2008 even though it is the poster-child of EMU competitiveness Finland tops the EU in the World Economic Forum’s index of global competitiveness. It comes 1st in the entire world for primary schools, higher education and training, innovation, property rights, intellectual property protection, its legal framework

The main differences between internet privacy in the US and the EU European privacy regulations are generally more consumer-focused than U.S. rules. “Who is the focus of these laws? Is it about protecting us, and giving us all the information we need and allowing us to make informed choices?”  “Or is it about allowing Comcast to keep up with Google and Facebook when it comes to

Cyber risks for Industrial environments continue to increase Industrial control systems (ICS) are a privileged target of different categories of threat actors. Researchers observed a significant increase of brute force attacks on supervisory control and data acquisition (SCADA) systems. In December, IBM warned of the availability of a penetration testing framework named smod that was used in many attacks in the wild.  Organization in any industry can

Mongoose OS Now Part of Hackster Apps – Hackster’s Blog An open source IoT operating system that looks interesting. Mongoose OS is an open source operating system for the IoT. With Mongoose OS, setup is fairly straightforward and takes just few minutes. Prototyping can be done in JavaScript, and you can use real microcontrollers for your projects (such as ESP8266, ESP32 or TI CC3200),

2D Materials Go Ferromagnetic, Creating a New Scientific Field – IEEE Spectrum Researchers at the Lawrence Berkeley National Laboratory have successfully demonstrated that two-dimensional (2D) layered crystals held together by van der Waal forces—these include graphene and molybdenum disulfide—can exhibit intrinsic ferromagnetism.  The discovery could have a profound impact for applications including magnetic sensors and the developing use of spintronics for encoding information. In general, electronics and optics are turning to
