But you cannot learn if you believe there is nothing left for you to learn. What if →

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. →

Then I think of ways of solving them.” →

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 →

http://www.networkworld.com/article/3200272/internet-of-things/the-top-7-linux-iot-projects.html It’s a Linux world, and the rest of computing is just living in it. IoT is no exception. The Linux Foundation lists these seven projects as the key players in the march of connected open-source systems. This article is a quick rundown on them. →

http://www.cnbc.com/2017/06/12/apple-co-founder-wozniak-motivation-is-more-important-than-knowledge.html The most important ingredient to becoming successful is having motivation, says Apple co-founder Steve Wozniak. “If somebody is motivated and wants to do something, wanting — it’s emotional. That’s the person that is probably going to go out and find a way to actually get it done.” The Internet has made it possible for anyone with the →

https://fossbytes.com/linux-on-windows-10-without-developer-mode/ With the release of Windows 10 Insider Build 16215, Microsoft has announced that now users don’t need to activate Developer Mode to run Linux on Windows 10. Now, Microsoft thinks that WSL is stable enough to remove this restriction. However, this change still keeps Linux an optional component and the users manually need to →
