Have you looked into how existing software handles captive portals. I believe, both Ubuntu (or Gnome or Network-Manager) and Firefox do check for such portals and detect real internet access. (They simple poll some URL http://detectportal.vendor.com and check for the expected return code. Portals usually redirect.)

Now I’m thinking, what if this check could trigger a change to the DNS configuration. That is use DoT when internet is available, otherwise fall back to DHCP announced DNS

That was also my question. A broader question is how to access services on the local network that are announced through local DNS? Like your router’s web interface or any similar device.

Can you have split routing? Most queries go to our preferred DNSoverTLS endpoint, but some go to DNS53 on the local network.

This would also solve the captive portal if the host used to detect captive portals is always resolved locally.

Point for you, root is special.

The x permission on directories is exactly for this purpose. You can use the directory. You cannot read (requires rx), you cannot write (w), but you can ‘cd’ and operate on files in the directory.

This is important, you can lock someone out from a directory tree buy not giving them ‘x’ on the root. So, if your home is rwx------, no one but the owner can do anything in your home. This is effective even if some files and subdirectories have less restrictive permissions.

We ignore them, mostly. You cannot miss what you don’t know.

There are plenty of options however to access software not available natively. Both VMs and Remote Desktop solution work for a wide range applications. Web-based solution can be as good as desktop programs.

So many casual applications are now either web-based or on your (not FOSS) phone, so for my personal use the thought of using Windows has never crossed my mind. Professionally, I resort to remote Windows or a Mac.

Interesting.

1. Ich bin kein Spieler, aber ich würde nicht davon ausgehen, dass ein nicht für Linux gemachtes Spiel ohne Tüfteleien läuft.
2. Non-issue. Du wirst nicht viel SW von Drittherstellern nutzen und wenn dann, um mit deren Cloud zu reden (e.g. Zoom)
3. Installiere irgendeine Distro, z.b. in einer VM.
4. Jede
5. Just do it. Dualboot und VMs sind keine Schande. Nutze web-basierte Dienste für die Kommunikation mit Dritten (z.b google für msil, cal, office, …)
6. (Vereinfachung) Entweder es (Hardware/Treiber, Software, …) funktioniert out-of-the-box oder gar nicht. Basteln ist leerreich, aber selten effizient. Eigentlich ist das 'Übliche' immer einfach.
7. Der Paketmanager (App Store) ist dein Freund. Software auf anderem Weg zu installieren führt immer zu Mehraufwänden.

Can someone explain what’s the point?

There’s some exam, online, runs in a browser. Ok.

Now we require a special browsers. Why?

Which only runs on Windows, but not in a VM, unless you make a small change. Why?

To stop cheating, I assume, but what kind of cheating needs a VM? Maybe I’m old, but we had handwritten cheat sheets on paper.

Are students using cheat software now that solves math problems for an online exam? And if they do, shouldn’t this score bonus points? Sounds like challenging problem to code an AI that she’s your exam.

That’s a complicated way to say:

• You can either run a server (headscale)
• Or use a manage service (tailscale)

Both comes at a cost, generally, but free options are available depending on your needs.

Someone should clarify if this

• leaks only the cc number (as shown here)
• or otherises a payment

Contactless payments use the EMV protocol. Leaking the cc number is bad, but happens all the time. An actual payment athorisation replaces both PIN and signature. The victim’s bank will argue that the victim authorised the transaction at the POS.

But sure what you ‘heard’. VNC essentially streams a video from either a real or a virtual screen. This has worked very well for all 2D applications for decades.

It’s not fancy, does nothing special, and that’s why it works. You need sufficient bandwith for the desired quality, but on LAN you’ll be fine

What’s usually problematic is fancy UI stuff that relies on a local GPU, which you don’t have. I usually disable animations.

Disclaimer: Have not used VNC in 10 years.

Also, many thinks you ask for are out of scope for VNC: clipboard, drag and drop, file access. VNC does none of those; just screen and input (keyboard, mouse, …). Not sure about audio.

The headline under the table says compression formats

This whole table raises multiple questions. I guess I’ll never hire someone mentioning comptia on their cv

So, Apple breaks all multipoint devices unless all connection are from Apple devices? Weird.

I settled on different headphones for pc/linux and phones. I can’t afford to have an important call interrupted by something less important from an other device. Also switching from phone to linux takes to much fiddling.

I don’t get this argument. Most business don’t own any property. The office buildings are rented.

Forget wine. Virtual Machines or Remote Desktop work very well for generic Windows software. For graphics-heavy stuff, you need to learn whether this works for you.

Ok, so via LUKS. Thanks

I have bought 2 tuxedos and they were okay.

One time they shipped a device where the trackpad did not work. Well, not on Linux at least. Their excuse: The hardware manufacturer chose a newer model not yet supported.

They were helpful and provided a new firmware a few days later, which did solve the issue, but out-of-the-box experience was not exciting.

I’m still using this machine, however.

Both this and a model I bought earlier felt cheaper than the price point. Maybe it is not fair; maybe it’s not that important, but at 1000€+ I have some expection on build quantity and loooks.

Those are small things, sure, but they are not perfect, yet.

This clearly goes against the intention of the GPL. Maybe not illegal.

Now THIS is a GPL-violation or at least a serious concern and asshole move.
