What I'm Reading (or Watching) 4/12/2020 - Happy Easter, Have Some Ethernet/IP To Celebrate

vedipen.com - Linux Bash vs Windows PowerShell -
With the addition of Linux subsystem in Windows and PowerShell having native support in Azure and Windows devices, having knowledge about both the scripting languages has become more and more important.
Personally, I used to be a diehard zsh user, but the most popular shell on Linux and Mac is ofcourse the Bash. I meet so many people day to day, who stay afraid of PowerShell and always find ways of running a bash on Windows wherever possible. This shouldn’t be the case.
Yahoo - Parts of the country could see coronavirus social distancing restrictions begin to ease by late May, say public health experts -
Much of the country is likely to see some social distancing restrictions ease by late May or early June, a top public health expert told Yahoo News on Friday.
Kavita Patel, a Yahoo News medical contributor and nonresident fellow at the Brookings Institution, heavily hedged her prediction in a wide-ranging interview with Yahoo News’ “Skullduggery” podcast. The situation is rapidly evolving, Patel said, and even where there are openings, some regions will be in lockdown far longer than others.
Julian Assange secretly fathered two children while living inside the Ecuadorean embassy in London, his partner has revealed.
Stella Morris says she has been in a relationship with the Wikileaks founder since 2015 and has been raising their two young sons on her own.
She spoke out amid fears over the spread of Covid-19 in Belmarsh Prison.
 Sydney Morning Herald - Hackers nab $4.7 million after tricking art museum over Old Master painting -
The criminals intercepted emails between Rijksmuseum Twenthe in the Netherlands and Simon Dickinson, a London art dealer, who were arranging the sale of Constable's 1824 landscape A View of Hampstead Heath: Child's Hill, Harrow in the Distance.
Posing as Dickinson, the seller specialising in Old Master paintings, they instructed the museum to pay £2.4 million into a bank account based in Hong Kong.
Medium -  Stuxnet, and the Case for Cybersecurity in Critical Infrastructure -
I’m glad that LTTE is not in an age where Sri Lanka would be fully digitized. The ease of disruption by exploiting cyber vulnerabilities would have been super easy for any such terrorist organization that would have made my parents’ biggest fears lame in comparison. Interestingly enough, we have not seen any cyber terrorist organization — apart from a few bad actors and government actors — committing cyber attacks on the level of Stuxnet.
What can we do to avoid such a future? I have a few ideas that I think any organization developing critical infrastructure software should try. ...
Predict - Technology’s Broken Promises -
As we turn down the little alley where the office is located Rex, the resident homeless man, asks if anyone could buy him a Mountain Dew.
“Sorry Rex, not today.”
With hindsight, this was perhaps my first of many quintessential San Francisco Hyper Techno Capitalist moments. The four of us are not rich by the Bay Area’s standards, but as twenty-somethings all four of us are making more than the median household salary. The joke almost writes itself: four yuppies walk through a rough-and-tumble neighborhood in San Francisco looking for a technological solution to the global problem of otherization — they pay $6000 dollars a month for what could have been a family home and collectively ignore a local homeless man on the way to a trendy, organic, vegan, restaurant.

Wikipedia - EthernetIP-
EtherNet/IP uses both of the most widely deployed collections of Ethernet standards –the Internet Protocol suite and IEEE 802.3 – to define the features and functions for its transport, network, data link and physical layers. EtherNet/IP performs at level session and above (level 5, 6 and 7) of the OSI model. CIP uses its object-oriented design to provide EtherNet/IP with the services and device profiles needed for real-time control applications and to promote consistent implementation of automation functions across a diverse ecosystem of products. In addition, EtherNet/IP adapts key elements of Ethernet’s standard capabilities and services to the CIP object model framework, such as the User Datagram Protocol (UDP), which EtherNet/IP uses to transport I/O messages. 
Previously known as Control and Information Protocol,[1] CIP encompasses a comprehensive suite of messages and services for the collection of manufacturing automation applications – control, safety, synchronization, motion, configuration and information. It allows users to integrate these manufacturing applications with enterprise-level Ethernet networks and the Internet. It is supported by hundreds of vendors around the world,[2] and is media-independent. CIP provides a unified communication architecture throughout the manufacturing enterprise. It is used in EtherNet/IP, DeviceNet, CompoNet and ControlNet.
