QEMU Windows Guest: Easy File Sharing with QEMU's built-in SMB

Last year I wrote about my efforts to share files in QEMU between a Linux host and Windows guest. Someone in the comments pointed me to WinFSP and WinSSHFS, and I was able to get file sharing working that way, after installing both those packages on the Windows guest.

But I recently found a much easier way, using QEMU's built-in SMB handler.

Create a Windows 10 that Boots off a USB Stick, from Linux

In 2019, I wrote about struggling to get any sort of Windows booting off an external USB stick, in order to Install Lenovo Firmware Packaged as a .exe on a Linux Machine. I ended up needing to borrow a real Windows machine and install Rufus on it.

In 2023, things are much better. Aki at atkdinosaurus has written a clear, concise tutorial on that topic: How to create a Windows 10 installation on a USB stick in UEFI mode. I love that it's all command-line, so you can duplicate the steps exactly.

Opening a URL in a New Tab of an Existing Browser Window

My search for a good desktop Mastodon client has led me down a path that involved learning some fun ways to interact with existing browser windows on Linux with X programs like xdotool and wmctrl.

Like many people, I've switched from The App Formerly Known As Twitter to Mastodon (where I'm @akkana@fosstodon.org). But the next question was which Mastodon app to use.

Zenity for Notification Dialogs

When I wrote about Getting Linux System Notifications under Openbox, I ended up tossing out the whole notification system and using zenity to pop up a dialog directly. Specifically, a command like XAUTHORITY=~/.Xauthority DISPLAY=:0 zenity --title "Hello" --info --text="Hello world"

But customizing zenity to make it more attention-getting turned out to be more difficult than expected ...

Getting Linux System Notifications under Openbox

I've been a fan of Linux's lightweight window managers, particularly Openbox, for many years.

But admittedly, there are some things they don't generally handle. One of those is system notifications.

Mostly, I've been happy to go without notifications. Firefox is forever asking me whether I want to turn them on for particular websites (which wouldn't work, but Firefox doesn't know that), usually websites I'm visiting for the first time and probably don't ever want to visit again, let alone let them spam me with ads as notifications outside my browser.

But every now and then it would be handy.

Triaging Videos Using VLC's Python Bindings

A few days ago I wrote about finding a way to triage videos by adding captions to mplayer. Better than nothing, but I really wanted something like pho or MetaPho where I could add the tags in the program itself, rather than keeping notes on a piece of paper.

Turns out it wasn't that hard using VLC's Python bindings.

Triaging Videos by Adding Captions to Mplayer

I've recently hit a wall that I'd been avoiding: how to triage a bunch of new videos and decide which ones are worth keeping.

For still photos, I do that with my Pho program if I just want to make yes or no decisions, or maybe mark two or three categories. When the time comes for real tagging — which images have sunsets, which have bicycles, which have coyotes and so on — I use my MetaPho. I take a lot of photos, so efficient triaging and tagging is important to me.

But what about videos?

A Tricky Website Bug After Upgrading

Someone contacted me because my Galilean Moons of Jupiter page stopped working.

We've been upgrading the web server to the latest Debian, Bookworm (we were actually two revs back, on Buster, rather than on Bullseye, due to excessive laziness) and there have been several glitches that I had to fix, particularly with the apache2 configuration. But Galilean? That's just a bunch of JavaScript, no server-side involvement like Flask or PHP or CGI.
