From what I’ve understood, there is a translation table of line thickness to power/speed, that can be configured in the driver.

Is there any way to use wero without handing out my mobile phone number to everyone? I’d prefer handing over IBAN or some alias over phone number.

The fact Ubuntu now withholds package updates unless you’re paying for their “maintenance and compliance subscription”

Do you happen to use a very old version of Ubuntu? You might want to update the distribution. This might also fix the bug you mentioned.

Is it possible that you are using a Linux distribution that still has Pulseaudio instead of Pipewire? That would cause unnecessarily high latency in the audio stack on the machine.

Do you happen to use a distro that excludes patent encumbered codecs? For example, if you were on Fedora, you might want to install pipewire-codec-aptx from RPMFusion?

Some companies allow specific Linux distributions (like RHEL) only. Maybe that’s something for your case too? At least there is “Enterprise” in “Red Hat Enterprise Linux” ;-)

GNOME shell’s overview search does almost the same.

Waydroid

I wouldn’t recommend using Waydroid, it basically runs Google Play services and other stuff as root on your machine.

Instead, it would be nice if we had seamless integration of virtual VMs including Android like Qubes OS does this.

Audio is a mess. To have low latency in my DAW (Reaper Linux Version), I have to launch it via the command line using pw-jack reaper, otherwise it won’t recognize the audio device or uses ALSA or Pulseaudio both of which have way more latency than JACK

Most modern linux distributions use pipewire, which should have lower latency than ALSA or Pulseaudio, if configured correctly even lower than Jack. You might want to try that instead, especially when updating your linux distro.

Regarding laser cutting: Some fablabs have been using Inkscape and just print the vector graphics to the laser cutter. Have you tried this?

For your audio quality: Have you installed pipewire-codec-aptx from RPMFusion? Fedora ships without patent encumbered audio and video codecs (and some other software) for legal reasons.

It might be worth trying out restic. If you prefer graphical user interfaces, the latest version of Déjà Dup should do the job.

As far as I understand, the latency is improved by the different speed of light of the DNANF: In conventional fibres, it is limited by the refractive index of glass, reducing the speed of light in it to ~70% of speed of light in vaccum (Wikipedia on this topic). In this new concept, the light travels 45% faster.

I think, the lower loss (lower attenuation) is “just” an enabler for long distances: You can easily have hundreds of km without repeaters – and repeaters for DNANF cables would add latency. If they can get attenuation improved a bit more, they may even be able to cross the Atlantic ocean without repeaters.

As a nice side effect, those DNANF cables have very little dispersion, so you can get rid of compensating for that, which will reduce latency too.
