A discussion about Debian LTS distro upgrade intervals on my Raspberry Pi Relevant links below Debian release information My previous episode from last year where I covered the upgrade on my raspberry Pi from Debian Jessie 8 to Stretch 9 A previous episode where I describe my raspberry Pi add-on board and what I use it for

I use email in the terminal with a combination of: protonmail-bridge-cli local IMAP server to fetch Protonmail mails tmux to run protonmail-bridge in isync (or offlineimap etc) to sync IMAP with maildirs notmuch to tag and search mails afew to move mails found by certain notmuch queries in certain maildirs alot to read, compose, search and tag mails msmtp to send mails w3m (or lynx etc) to read HTML mails in the terminal rsync to copy archived mails a shell function and an alias to make it all less ridiculous To most, Thunderbird will be suitable, the target audience here is unreasonable people.

I did a show about why I do not listen to non-mainstream podcasts as much as I used to. For me two things happened: I switched from being in the car for 16 hours a week to being a remote sales person at home. So the 16 hours I listened to podcasts every week in the car went away. The second reason I reduced was that many of the podcasts I was listening to were presented by people who do not share my values. So I stopped listening to them. The third reason I listen less is the Army opened up the online book library to retired service members and I do a lot of audio books in the moment.

Just a basic podcast about a tablet. https://www.walmart.com/ip/onn-7-Tablet/930669857

When listening to HPR 3442 by Klaatu, which I recommend, some thoughts about how we think started rattling about in my head. In this show I riff on that and talk about the importance of our irrational mode of thought.

Notes on the audio quality I have been looking into the audio quality issues of my shows. I think I have found a solution to them. Unfortunately, this show was recorded before I discovered it. Synopsis In today's episode, I take the audience along my adventure in backing up my laptop's hard drives. During recent OS updates, the kernel updates started to fall. In my efforts to resolve the problem, I made things worse – to the point I decided it was time to reinstall the operating system. To prevent any data loss, I chose Clonezilla to image the drives. The Clonezilla Live edition lets you boot into a ncurses menu driven system that walks you through the process of either backing up your hard drives or restoring a Clonezilla backup. Clonezilla backups save space by imaging only the data on your drives (for those filesystems it recognizes – otherwise it uses dd to do a sector-by-sector copy) Overall the process was very smooth, and, at the end, I was confident to move forward with wiping my main hard drive and reinstalling the operating system knowing I had a way to restore any lost data.

Title: Metal marbles. Summary: Introduction of host, with reference to semantic playgrounds. Link to the rust converter recipe, which I found to be cheaper, and more sprayable than buckets of gel or paint-like substances which you might find elsewhere: https://www.canada.ca/en/conservation-institute/services/conservation-preservation-publications/canadian-conservation-institute-notes/tannic-acid-rusted-iron-artifacts.html In case that link moves, search for tannic acid rust converters, then choose your buffers.

We didn't have time to tackle the discussion in last months community news so today we dedicate an entire show to reading out all the comments relating to the HPR Branding. See http://hackerpublicradio.org/pipermail/hpr_hackerpublicradio.org/2021-October/thread.html Your comments are appreciated !

Layer Modes, sometimes called Blending Modes, allow you to combine layers in a variety of ways. We continue with the Dodge and Burn Modes. Dodge is one of the Lighten Modes, while Burn is one of the Darken Modes, but I pulled them out for their own tutorial because they are not only closely related (inverse of each other), but also because I wanted to cover their use as Tool Modes in addition to Layer Modes. These are the Layer Modes available on the latest (at the time I write this) version of GIMP, 2.10.24.

Apart from riveting insights into open source licensing we discuss the greater FLOSS ecosystem and Deb's views on why wearing shoes is important in certain contexts, open source standards, law suits and the differences between US and Europe among other things.

Mobile devices don't display them nicely. Most tables can be converted into a list: OSInitPkg Fedorasystemddnf SlackwareBSD-styleslackpkg GentooOpenRCemerge Can be represented as a list. In YAML terms, this is a sequence of mappings. Fedora Init system: systemd Package manager: dnf Slackware Init system: BSD-style Package manager: slackpkg Gentoo Init system: OpenRC Package manager: emerge A table doesn't always translate exactly to a list, but it probably can be restructured. OSOpen sourceLanded on Mars LinuxYesYes BSDYesNo macOSNoNo Could be written like this instead: Linux and BSD are open source operating systems, while macOS is not. Of these POSIX-compliant systems, only Linux has landed on Mars so far. That's pretty casual and loses the visual impact of a table or a list. So alternately, you could summarize what's common and highlight differences: There are a few Linux systems on Mars. Neither BSD or macOS have yet landed on Mars. Linux and BSD are both open source. macOS is based partially on open source and includes components from the BSD, KDE, GNU, and other projects.
