If you “vibe code” your way through trial and error to an app, it may work.
But if you don’t understand what it’s doing, why it’s doing it and how it’s doing it?
Then you can’t (easily) maintain it.
If you can’t fix bugs or add features, you don’t have a saleable product - you have a proof of concept.

AI tools are useful, but letting the tool do all the driving is asking for the metaphorical car to crash.

The concept of direct brain interface is both exciting and terrifying.
We struggle to secure offline systems against determined attack, and my brain is not a test bed.

I can’t think of a standalone gui app that does this (and a simple google search didn’t find one).
If you have a gui desktop (gnome,kde,xfce,lxqt,enlightenment,budgie…) it will have a built in function in it’s settings to do this, or leverage one of the parent ones (ie budgie is based on gnome, lxqt on kde).
If your custom environment is pared down to the point where you don’t have an equivalent to gnome-system-tools and don’t want to install it, you might have to just use date at the command line.

Honestly sounds like a job for a Raspberry Pi Zero.
Small battery pack and a USB key, a bit of software setup, off you go.

Install Raspbian: https://www.raspberrypi.com/documentation/computers/getting-started.html#raspberry-pi-imager

Set it up as a hotspot:

I have a friend group that insist on all events being planned through facebook.
I’ve missed out on events in the past due to not taking part.
It’s no longer a hill I wish to die on.

I agree and use Signal myself.
But people like the extra features of WhatsApp like desktop/web clients with seamless history sync and all the other little things that WhatsApp provides.
The average Joe doesn’t even think about security or privacy, they just know that the results of using WhatsApp are superior than using SMS.
iMessage is a non starter everywhere out of the US, it just doesn’t have the market penetration.
As an Australian, no one I know (many of whom own iPhones) talk about the blue-green bubble stuff.
They recognise where the fault lies and simply don’t use the app.

In certain places like India, WhatsApp is the default means of communication for everyone.
You can use it without phone data if you are on wifi, it supports better quality than sms for sending images, you can video chat with it, it’s cross platform, etc etc.

What’s more amazing to me is that it’s not more popular in western countries.

I think all the existing answers are on the basis of creating a new Linux VM.

And if I understand you correctly, you already have a bare metal Linux install that you want to run whilst Linux is up.

This is the best search result I could find: https://forums.virtualbox.org/viewtopic.php?t=93437

It sounds like Virtualbox will indeed create a pseudo vhdx that points to a real partition, but windows is going to give you permissions drama.

The above link is out of date though, so its best viewed as info rather than guide.

Good luck.

A lockdown browser?

If you need to use windows because of a software issue, not a hardware issue, you’re probably best off running windows in a VM.
That way your linux install is making the WPA3 connection, and as far as the Windows install is concerned, it’s on a wired lan.
This has the added benefit of not having to reboot, you just always start linux and turn the windows VM on and off as required.

My gut suggests it’s a font issue, like librewolf is using a system font and firefox is using embedded or downloaded fonts.

backing that up with a search, I see there’s lots of people complaining of font rendering issues of various types in the librewolf subreddit: https://www.reddit.com/r/LibreWolf/search/?q=font

I don’t know what your fix is, but I hope this helps guide you.

TOTP is a defined standard, specifically RFC 6238.
But I still have 3 different apps on my phone so that I can get on to various customer VPNS. 🤷‍♂️

Windows XP is basically firmware at this point, and has been for over a decade.

Lots of proprietary hardware that works perfectly, will not work on newer versions of Windows due to lack of drivers.

I see it constantly in factory situations with scales, scanners and robot controllers, it would only be worse for million dollar x-ray machines.

I don’t think it’s strictly compliant, although they claim to have based it’s syntax on Korn shell, which is the strictest definition of POSIX shells.

You can do pretty much everything in powershell that you can do in something like bash BUT, it will be done slightly differently, so trying to make a script cross compatible is pointless (you might as well just write it natively in powershell etc).

Powershell isn’t inherently bad, unlike bash for instance which just allows piping out text output, Powershell can pass around true .net objects.
But if what you’re looking for is cross OS compatability, you’re pushing shit uphill.

99.9% of the time, I open powershell and just ssh into a “real” linux box.

FOSS is enshitification-hardened, not proof.

VLC remains awesome because the guy (maybe Jean-Baptiste Kempf?) that controls the project has refused to be bought, has in fact refused HUGE sums of money.

The original author of any project has to right to sell it with the corresponding licence changes at any time.
There’s some legal grey area on something like Linux or VLC which have MANY MANY developer hands in the pie, and existing users could certainly fork off the existing releases, but VLC could pivot tomorrow to a for profit company and make future releases of the official VLC a paid product, if they choose too.
