Google Messages for the Web is a useful piece of software I've "installed" on my Linux machines, mostly because I'd rather manage texts on a 24" monitor than a 6" smartphone screen. That's possible because Messages is a Progressive Web App (PWA) that can be setup on a desktop using any Chromium-derived web browser, in this case Brave on Linux Mint 22.3 (Zena):

1. Open Brave browser and go to https://messages.google.com/web
2. Authenticate by "Pair with QR code"
3. Click on the tiny computer icon over on the right-hand side of the address bar
4. Select [Install]

At this point the Messages "app" will show up on the Mint menu under "Brave Browser Apps", but it will be lacking the Messages icon. To get that:

Create a udev rule to lock in the physical network interface name assigned by Linux, so that the system won't change it the next time a PCI device is added or removed.

Create /etc/udev/rules.d/10-network-names.rules, and then edit as follows:

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="xx:xx:xx:xx:xx:xx", NAME="enpNxN"

"ATT{address}" is unique MAC of the physical network device (seen in output of ip addr), while "NAME" is the interface name assigned to it by Linux (this will usually be something like "enp6s0".

"No pain, no gain"

Some notes on the process of heading off the next upgrade apocalypse.

Loosely acknowledges the existence of the official Linux Mint Installation Guide.

Brave is a fork of Google's Chromium that provides a privacy-respecting alternative to the commercial Google Chrome browser. I use it where LibreWolf won't work at all or without unreasonable effort, like when I need WebUSB or a site's code spectacularly fails to conform to web professional best practices.

It goes without saying that what follows reflects my experience on Ubuntu 22.04 LTS desktop at a moment in time. Like many other software apps, the availability and configuration of some features change over time: so YMMV!

Brave works on all platforms. Since I'm currently on Ubuntu desktop, I follow the installation instructions for that distribution.

The defaults for Brave are pretty reasonable, but here are the changes I make in Settings:

IronFox is a privacy-minded fork of Firefox mobile for Android. It comes recommended by the LibreWolf project, who have a similar privacy focus for the desktop. What I like most about both of these forks is that their choice of defaults requires minimal effort on my part to set up and maintain my primary browser.

Because I already make use of F-Droid for installing open source apps that are not included by Google's Play Store, I have added IronFox's standalone F-Droid repository to the F-Droid app on my Android devices and use that to install IronFox.

Here are the changes I make to Settings in IronFox after installing:

1. Open browser and accept the setup defaults (choose Cloudflare as DNS-over-HTTPS provider)

LibreWolf is my standard desktop browser. It is a Firefox fork that makes my llfe easier by having sensible privacy defaults out of the box.

As I am currently on a Debian based distribution (Linux Mint), following these instructions.

Because of its shipping defaults, I have found LibreWolf quick and painless to configure. Here are the changes I make in Settings after installing:

1. Home > Homepage and new windows > Custom URLs: enter my personal homepage URL
2. Privacy & Security > Enhanced Tracking Protection > Strict > Fix major site issues: Check (enable)
3. Privacy & Security > Delete cookies and site data when LibreWolf is closed: Uncheck (disable)

The decision to disable/change the venerable Ctrl-Alt-Backspace keyboard shortcut for killing the X server in the Ubuntu/Gnome desktop has been a persistently unwise one.

At least for now, the most straighforward way to restore it is to install gnome-tweaks. Then go to:

Keyboard & Mouse > Additional Layout Options > Key sequence to kill the X server

Ctrl+Alt+Backspace: checked

Recent releases of Android famously ignore/bypass any local (i.e., self-hosted) nameserver passed along by DHCP or specified in a wifi profile, in favor of Google's own public nameservers. The only other option is to enable "Private DNS" (DNS over HTTPS, or DoH) in the global network settings for your devices. The stated reason for this are easy to understand: to avoid compromising security or privacy when connecting to random wifi networks. But we all know there's more to it than that. The most charitable explanation would be that Google (and others, including Mozilla) is fixated on getting everyone on DoH, even at the cost of frustrating we few peasants who want to run our own local DNS. Let them eat cake.

There are a few alternatives available to those of us who would like to address local hosts and services on our home networks by name, rather than IP address:

1. Apple mDNS. Like Microsoft's legacy WINS, mDNS still isn't very reliable and won't work for hosts and device

Alexandre Lotte, the author of icsp describes it as a "Small, fast and simple command-line tool to conver calendar exports (.ics files) into TSV/CSV files for easy analysis and usage in broader use-cases."

And so it is.

I had accidentally imported a holiday calendar into my default Proton Calendar, when I realized two very horrible things: (1) I had no backup; and (2) no one really provides tools for removing entries from calendars in bulk. Later, I would add "Proton Calendar doesn't have a versioning system". But then, no one else does either.

I was screwed.

A few minutes (OK, about a half hour) of searching the Internet, and I found icsp: which turned out to be everything its author wrote that it is.
