Sometimes you are stuck. Then this often helps, even outside the music industry:
[WayBack] Oblique strategies – defeat creative block: Draw random Oblique Strategy cards to break through creative block.
These are disruptive which is the whole point being stuck.
Obey the first and only rule: pick the first card and apply what it says.
Both above failures kill the randomness of the above strategy.
More on them at [WayBack] Oblique Strategies – Wikipedia

A while ago, I had to execute a series of aliases of which the names were stored in an array. A simple for loop with en eval call did the job.
Then I found out there are at least two more ways of evaluation in bash, so here are just a few links giving me a head start if I ever dig this up again:
Note that looping over parameters is different than over an array: [WayBack] Loop through an array of strings in Bash? – Stack Overflow
ou can use it like this:
## declare an array variable declare -a arr=("element1" "element2" "element3") ## now loop through the above array for i in "${arr[@]}" do echo "$i" # or do whatever with individual element of the array done # You can access them using echo "${arr[0]}", "${arr[1]}" alsoAlso works for multi-line array declaration
declare -a arr=("element1" "element2" "element3" "element4" )

The PlasticSCM GUI does not allow you to edit the paths of Workspaces (you can either rename a workspace or delete edit; no other editing options are available).
Luckily you can do this by hand editing the configuration files in %LocalAppData%\plastic4, though this is largely undocumented
Some of those configuration files are explained in [WayBack] Configuration files – Installation and configuration – Plastic SCM Community, but plastic.workspaces is not, so here are the steps:

I’ve added this to my ~/.bashrc to stuff installed by pip install --user is accessible from interactive shells:
# set PATH so it includes user's private python "pip --user" bin if it exists
if [ -d "$HOME/.local/bin" ] ; then
PATH="$PATH:$HOME/.local/bin"
fi
The addition is at the end of the path. It is a choice: it means machine installs take prevalence over user installs. That’s usually what I want. For more considerations (including non-interactive shells), see [WayBack] bash – How to correctly add a path to PATH? – Unix & Linux Stack Exchange.
The --user installs do not affect the full system, nor other users.
Further reading:
--user installs in site.USER_BASE which luckily is the same for Python 3 and Python 2: [WayBack] Python 3 site.USER_BASE, [WayBack] Python 2 site.USER_BASEvenv, virtualenv, easy_install, easy_build, pip install --user and such as even this SO question has inconclusive answers: [WayBack] What’s the proper way to install pip, virtualenv, and distribute for Python? – Stack Overflow–jeroen

This is part of a bash alias where I had to use quadruple backslash in order to escape it for sed:
# The sed with quad //// is to prevent 'unterminated substitute in regular expression':
alias x='... | sed "s/=.*/ \\\\/"'
This is needed because bash will escape \\\\ into \\ which sed then escapes to \.
The easiest way to find this is to replace the sed with echo to see the expansion.

Cool:
use command:

For a really nice overview of most basic and intermediate usage of ssh, read [WayBack] SSH Essentials: Working with SSH Servers, Clients, and Keys | DigitalOcean.
It is large (printed to PDF it is 30+ pages in either A4 or Letter format) but well worth reading as it covers a lot in manageable bits.
Does it mean I won’t write about ssh again?
I will continue, as most of my blog posts are relatively short highlighting a small thing at a time (that is how I learn best, hopefully some of you do as well).
It does not explain really advanced stuff (like ProxyCommand), so here is a start of things I want to learn more about:
~/.ssh/config file with Host entries.
Too many authentication failures:
nc is not needed, so disregard the examples promoting it–jeroen
