By now, probably newer versions have come out, but this should give a rough indication of the 2019 state of [WayBack] PowerShell OS Support Matrix – mohitgoyal.co:
For 5.1 and lower, you can find the prerequisites in [WayBack] Windows PowerShell System Requirements – PowerShell | Microsoft Docs.

Interesting thread: [WayBack] SwiftOnSecurity sur Twitter : “I had this issue in my prev company network. QoS will drop ICMP and you’ll chase your tail. If you want to find out if a network service works, test the service. If you want to know if TCP works, use TCP.… “
So:
tcpping and tcptraceroute for the win![WayBack] Zimmie on Twitter: “It is perhaps worth noting: traceroute does not generally use ICMP. Instead, it uses this horrific UDP port range with a different port for every probe at every hop. 30 hops? That’s 90 different UDP ports you just tried. Makes its value questionable at the best of times.…”

If you get [WayBack] “A parameter cannot be found that matches parameter name ‘PassThru'” as PowerShell error, then likely the PowerShell version is too old to support -PassThru, which likely means you have are running pre-Windows 10 version.
PowerShell 3 (introduced in 2012) added the -PassThru parameter that allowed to chain multiple commands from one list pipe.
Another reason for the error might be that the command you use does not support the -PassThru parameter.
To check which commandlets support -PassThru, use the below command (the output is from a Windows 8.1 machine running PowerShell 4.0).

After bumping into yet another occasion where a tool did not properly save after saving: [WayBack] checkdigits on Twitter : “CTRL+S is the new carriage return. Type line of code, CTRL+S to save, start new line of code. #NotParanoid 😬…”
in a response to [WayBack] Dare Obasanjo on Twitter: “No one I know who works on software for a living trusts it to do anything important. That people assume software can be trusted for important things like voting or driving cars when I can’t even trust my follower count is correct is the biggest trick we’ve played as an industry.… “

Long interesting thread at [WayBack] Thread by @sleevi_: “@SwiftOnSecurity So, some history: It used to be folks would get certs for “localhost”, just like they would from “webmail”, despite no CA e […]”
In 2019, applications were still using tricks (including shipping private keys!) to “securely” access https://127.0.0.1 on some port.
This should have stopped in 2015, but hadn’t. I wonder how bad it still is today.

Infinity is not a number and you cannot do arithmetic with it. This means that in mathematics, in contrast to what some people believe, infinity times zero might not equal to zero.
As infinity as mind boggling to most, two interesting videos below.
The first about infinity times zero, the second about some interesting paradoxes around infinity.
But first a few other links:

So I won’t forget: [WayBack] @nixcraft on Twitter: Instead of typing the following on your Ubuntu/Debian/Mint Linux desktop: sudo apt update sudo apt upgrade -y Do to save typing and time at the CLI (add to your shell startup): alias update=”sudo sh -c ‘apt update && apt upgrade -y'” See for more info:
[WayBack] How to run multiple commands in sudo under Linux or Unix – nixCraft:
sudo syntax to run multiple commands
The syntax is:
sudo sh -c 'command1 && command2'
sudo -- sh -c 'command1 && command2'
sudo -u userNameHere -- sh -c 'command1; command2'
sudo -- sh -c 'command1; command2'
sudo -- bash -c 'command1; command2'
sudo -i -- 'command1; command2; command3'
sudo -i -- sh -c 'command1 && command2 && command3'…
UNDERSTANDING SUDO COMMAND OPTIONS
- -- : A — signals the end of options and disables further option processing for sudo command.
- sh -c : Run sh shell with given commands
- 'apt-get update && sudo apt-get -y upgrade' First update repo and apply upgrades if update was successful.
…

Here is a sample shell script that shows how to use or run multiple commands with sudo:
