https://opensource.com/article/17/6/5-totally-incorrect-ways-exit-vim?sc_cid=7016000000127ECAAY Vim can be a challenge to learn. But for many first-time users, just exiting the program can be a problem. This article gives solutions to this serious problem that many Linux/Unix users face every day. →
http://www.zdnet.com/article/how-to-use-linuxs-built-in-usb-attack-protection/ USB is insecure. There are USB sticks that will destroy your computer, USB sticks loaded with spyware, and even official enterprise USB sticks infected with malware. Windows and Macs are easy to crack with USB-borne tools. There are devices like the USG USB stick firewall, which can protect you. Linux users can stop attackers armed with USB sticks with USBGuard software. →
https://horizon-magazine.eu/article/europe-joins-forces-create-largest-shared-data-folder-history_en.html World-leading research institutes have agreed to join forces with funding agencies and policymakers to create the European Open Science Cloud, the largest shared data repository in history. The idea is to give every scientific user access to the data resulting from research carried out with public funding, using a single login. ‘Science has outgrown →

https://opensource.com/article/17/6/bash-parameter-expansion?sc_cid=7016000000127ECAAY In Bash, entities that store values are known as parameters. The wealth of parameter expansion modifiers transforms Bash variables and other parameters into powerful tools beyond simple value stores. →
http://www.edn.com/design/led/4442091/LED-current-regulator-has-low-dropout?utm_content=buffer1967d&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer This article has an intetesting LED current regulator circuit idea built using transistors. The voltage drop on the current sensing resistor r is less than 40mV. The nominal LED current here is 7.2 mA at 9V. Increasing to 20V causes a current change of +15%, giving a dynamic resistance of about 10kΩ. →

https://www.cyberciti.biz/tips/bash-shell-parameter-substitution-2.html The $ character is used for parameter expansion, arithmetic expansion and command substitution. You can use it for manipulating and expanding variables on demands without using external commands such as perl, python, sed or awk. This guide shows you how to use parameter expansion modifiers. →
http://securityaffairs.co/wordpress/60013/hacking/ics-cybersecurity.html The equipment was expected to be installed and left alone for a long time. Pressures to reduce operating costs led to this equipment being connected, and the easiest networking equipment to find was designed for convenience in a corporate environment — not security in an ICS environment. This has led to the current situation where malware →
