Veronica Explains

Ever want to eject a flash drive but you can't because the device claims that it's "busy"?

In today's Lil' Linux Lesson, we dive into the fuser command! The fuser command is one of those Linux utilities that you don't realize you need, but once you learn it, you'll find you're using it all of the time.

You asked for it, you got it. Here's what I think of Red Hat.

Sorry this video took a bit longer than I'd like, since I'm working on finishing my basement (future recording space) at the moment.

Anyway, I'm not planning on dwelling much on Red Hat beyond this- my plan is to move forward with community-driven distros in mind, and recommend those to customers in the months and years ahead. I hope Red Hat gets to a good place again. We'll see.

Supporters make this possible. Seriously, nobody's sponsoring this video except you!

My new keyboard is nearly as old as I am!

In this exciting episode of Veronica Explains, I share my most recent vintage computing find, an actual factual IBM Model M keyboard!

This keyboard - an IBM Model M 1390131 to be precise - is a legend for excellent feel and longevity- this one is from 1986 and feels (and sounds) like a dream.

It's not just show-and-tell in today's episode, though- I'll be going into how I got it set up with my modern USB-only computer using a Soarer's Computer- an excellent adapter which lets me remap keys, program macros, and other fun stuff.

It's super neat and I hope you enjoy it!

The modern web can be distracting, invasive, and slow. Luckily, there's another way!

Using an RSS/Atom feed reader can really help cut out distractions. Doing so from the terminal can enhance the effect, keeping you informed without all of the adtech and algorithms.

Enter Newsboat! Newsboat is an open source fork of Newsbeuter, and is a wonderful terminal-based feed reader. I even fire it up on my old Wyse terminal in the video!

In this video, I explain how to install and configure Newsboat on Manjaro, Fedora, and Pop!_OS. It's packaged up for other distros too, and non-Linuxes like macOS (via Brew) and FreeBSD.

Shout-out to Christian from @The Digital Life for helping out my pronunciation! This video also has some footage of @Techno Tim and @Learn Linux TV , both of whom are great.

If you want to help support the channel, you can join the Patreon at https://patreon.com/VeronicaExplains. For $10/mo, I'll print your name on my dot matrix printer and put it in the video. Super neat! There's also a $1 and $5 tier- any little bit helps me spend more time making videos!

Lastly, the shirt is at https://vkc.sh/merch. I know you're wondering! :) Proceeds benefit the channel!

The reports of the death of the dot matrix are an exaggeration!

In this episode, we explore the dot matrix printer, how impact printers work well with carbonless printing, and how you can connect to a dot matrix printer using Fedora Linux. You can even hook an old parallel, centronics, or serial printer up to a modern network using an HP JetDirect print server!

You might find this interesting as well- I don't have a fast enough camera to capture this sort of thing, but this video shows exactly how the pins in a dot matrix printer work, and it is super neat: https://www.youtube.com/watch?v=zk3iJJ9PpDY
