This is already a thing in IPv6 pretty much. You can write applications IPv6-only and support IPv4 via IPv4-mapped addresses (::ffff:1.2.3.4 for the IPv4 1.2.3.4). The host still n…

The problem is that IPv4 has no provisions to be forward-compatible with anything with a larger address space. Thus whatever replacement you can think of will have the same problem…

For applications that were written with X11 in mind it works much much better than that. One example was the controlling a telescope. The computers in the control room were thin cl…

> For SSH forwarding you could have SSH ask the X server for a new socket for forwarding purposes - so remote clients can't snoop on local clients. SSH pretty much already does thi…

Some aspects of the client isolation are used by default when doing X11 forwarding via SSH. A remote keylogger will not work for instance.

IPv6 clients (or in theory any kind of IPv4 successor) can reach IPv4 servers via some kind of translation layer (for example NAT64) - so IPv6 is backwards-compatible with IPv4 in …

Reliability is certainly one aspect where dedicated tracks helps a lot, but is not the only solution (see for example Switzerland). For Germany the issue is the overall too large u…

That has very little to do with the ICE train itself though, which can do above 320 km/h just fine in regular service (on international connections though, since in Germany the glo…

If I read the datasheet correctly you still need an inductor and some passive components externally. The only thing that is not needed is an external switch mode power supply chip.…

The X11 primary selection buffer is an even better variant of that though. It allows single-shot copy&paste (meaning only one application can grab it) from the password manager to …

Nothing preventing you from writing a X11 server in something else either (and people have done so!). But fact is, most wayland compositors right now are either pure C or C++ (and …

It is only one old C codebase however (or a couple if one counts the *BSD semi-forks separately) instead of many different fresh c codebases (one per compositor with some shared co…

X11 does have various ways to restrict access (one of which ssh does use for instance) and some more advanced security extensions. But as far as I can tell there has never been tha…

Maybe the problem was with your specific setup or applications? Because at the observatory it worked flawlessly. Between the local data reduction machine (beefy server) and the des…

That's perfectly possible with X11 to attach via VNC to an existing session. But what X11 over (local) network does way better than either RDP or VNC is to run individual applicati…

That is not true. There are extensions to the X11 server that can resolve many of the security issues, but almost no one cares enough to use them. If you are doing X11 forwarding v…

Not sure having shared memory and socket open to N fresh and under active feature development c codebases is that much more conducive to security? (N since while many compositors u…

There seems to be XACE/XSELinux, which seemingly exists in the mainline Xorg distro now. I wonder how the experience is with that? In practice I think it doesn't see any adoption, …

Only for IPv4 destinations however, where there is no other way. For IPv6 destinations it's just native connectivity with no NAT.

What do you mean it has never been tried? That's how a lot of mobile providers and home internet providers operate today. My provider in Germany was already using DS-Lite (native I…

That 22k limit is only for the small business rule, which allows the choice of not collecting VAT on sales (but on the flip side cannot deduct it on purchases). Up to a yearly reve…

There are 2M sole proprietorships in Germany and around 0.4M partnership type companies (Personengesellschaft; GbR, etc.) and aside from the aspect of trying to appear like a large…

The relevant part is that they moved from another city to Munich, which means that certain company taxes would be paid in Munich instead of Unterschleißheim (the city where the HQ …

Because it gets repeated on every thread on IPv6. IPv6 is perfectly backwards-compatible with IPv4 (you can run an IPv6-only host and still access hosts from the IPv4-internet). Th…

Windows actually used to have 6to4 setup by default in the past. There is no need to manually configure anything since the 6to4 have a globally unique anycast address and the ipv6 …
