Thank you to everyone who has listened to my previous episodes. This is the final episode in the Infosec Podcasts series.
I listen to many, MANY podcasts. The vast majority of these are related to information security.
Because there are so many podcasts to list, I have broken them down into 6 different episodes based on topics:
Preamble
Term: CISO
Security leadership is changing
Old way:
New way:
Infosec Leadership Podcasts
That wraps up this series. I welcome any feedback you might have in the comments section for this episode on the HPR site.
Thank you very much for listening.

Script breakdown: upg.sh
First, we declare bash as our shell with #!/bin/bash. We could also use #!/bin/sh for a more portable script.
I like to paste the name of the script we're working on into the script itself # upg.sh.
Setup a couple of variables to shorten the syntax.
FILENAME=sys-upgrade$(date +%m-%d-%Y).md
DIRECTORY="${HOME}/Documents/"
# step 1: formatting.
echo -e "# **System Upgrade:** $(date)\n" \ <-- formatting: label with date.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
echo -e "**Command:** \`sudo apt-get update; sudo apt-get upgrade --yes\`\n" \ <-- formatting: command label.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
echo -e "**Command Breakdown:**" \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
echo -e "- \`sudo\`, Admin Privilages." \ <-- formatting: label.

PKGCACHE=$(echo -e "${PKGLIST}\n" \ <--| variable with massive apt-cache search results.
| xargs -n1 -I _ apt-cache search _) <--| xargs runs the PKGLIST (the _ is the value of PKGLIST) into the apt-cache search.
echo "${PKGCACHE}" > ${DIRECTORY}delete.txt <--| I had to put the PKGCACHE in a file. I couldn't get sed to filter a variable (yet).
echo "${PKGLIST}" \ <--| use that PKGLIST to create a few sed commands to filter the file called "delete.txt".
| xargs -n 1 -I _ echo "sed -n '/^_ /p'" "${DIRECTORY}delete.txt" \ ^--| xargs is used to create the sed commands.
| bash | tee -a ${DIRECTORY}${FILENAME}; <--| run the sed commands through bash then store them.

| tee -a ${DIRECTORY}${FILENAME}
rm -v ${DIRECTORY}delete.txt; <--| use rm to delete the file called "delete.txt" it has the apt-cache search results in it.
PKGLIST= <--| empty the variable. why? why not!
PKGCACHE= <--| empty the variable. why? why not!
# step 4: place EOF (end of file).,
sed -i '/EOF/d' ${DIRECTORY}${FILENAME} <--| search for EOF then remove it. we don't want multiple EOF if we run the script multiple times in the same day.
echo "EOF" >> ${DIRECTORY}${FILENAME} ^--| adds the EOF (End Of File) at the end of the file. I read it was a nice thing to do.
#EOF <--| Yep. it's there.

Setup a couple of variables to shorten the syntax.
FILENAME=$2$(date +%m-%d-%Y).md <--| the "$2" is the second user input (file name) from the commandline.
DIRECTORY="${HOME}/Documents/"
# step 1: create file with formatting.
echo -e "# **Command:** \` $1 \`\n" \ <--| the "$1" is the first user input (the command) from the commandline.
| tee -a ${DIRECTORY}${FILENAME}
echo -e "**Command Breakdown:**" \
| tee -a ${DIRECTORY}${FILENAME}
echo "$1" | tr " " '\n' \ <--| This just breaks the command into parts then adds some markdown formatting for use to add -
| awk '{ print "- `" $0 "`, info." }' \ ^--| details to later. I just added the word info so you know to provide info about the command. -
| tee -a ${DIRECTORY}${FILENAME} ^--| the formatting gets a bit crazy if you use something like: awk {' print $1 $2 $3 '} path/to/file; each space becomes a newline with the markdown formatting.
# step 2: run command with more formatting.
echo -e "\n**Command std-output:**" \

Layer Modes, sometimes called Blending Modes, allow you to combine layers in a variety of ways. We'll begin with the Normal modes and work our way through many, but not all, of the Layer Modes available on the latest (at the time I write this) version of GIMP, 2.10.20.
This episode is dedicated to tiny kernels driving operating systems also known as micro-kernels. While discussing the last 100 years of operating system design and implementation, our two aging heroes also shed some light on operating systems in general and their recent history (like fifty years). Unless you're a true OS nerd, you find the episode mildly refreshing and educational on the layers of software underneath your beloved applications controlling the hardware and other shenanigans. If you're an OS nerd, this episode may have the potential of closing your few remaining knowledge gaps (or something like this). A fun show for children of all ages and beyond.

In this video I talk about 4 different computers that could be used in a ceph cluster and what I use and what could be good solutions. If you want to have a visual aid I've created a youtube video talking about the same thing.

This is the LWN.net community event calendar, where we track events of interest to people using and developing Linux and free software. Clicking on individual events will take you to the appropriate web page.
This month 10 additional shows in the range 1-870 have been uploaded.
Since we don't want to upload shows without summaries or tags the old shows and tag and summary projects are now tied together. So we will be all the more welcoming of tag and summary updates submitted as described on the summary page.
Thanks to the following contributors for sending in updates in the past month:
Archer72, Rho`n, Ken Fallon, Dave Morriss
Over the period tags and/or summaries have been added to 108 shows which were without them.
There are currently 114 shows which need a summary and/or tags.
If you would like to contribute to the tag/summary project visit the summary page at https://hackerpublicradio.org/report_missing_tags.php and follow the instructions there.
I talk about some old old old pentesting stories from days old!
