First, I've got to admit that i don't have a 3D printer, but I have a friend who prints stuff for me.

For this project, we need ABS as material. My friend has several years of commercial experience and research in this area, so it take this as granted.

While he has a good match for "Light Bluish Gray" and "Dark Bluish Gray", his "Blue" is off in comparison to blue LEGO bricks.

Has anyone found a close match that would be worth trying?

I plan to make a BIG pot of onion gravy soon. Is there a rule of thumb about the volume and weight relation of sliced onions?

So, my big pot holds about 12l - I'd go for 10l here to have room to stir - if thinly sliced on a mandolin, how many kilograms of onions would that be?

Or, the other way round, if one slices a kilogram of onions, how much volume would that fill?

Looks like Jesus took the wheel.

I've got an HTML file on my phone, and would like to view it. But Firefox on Android has neither a menu entry "Open File", nor does using the file:// method work, nor is any app associated with the .html file extension.

BTW, Chrome suffers from the same problem. And it is not an issue with the file, it works when opened via the https:// method from my home server.

Why, oh why, can't I open a local file on Android?

Although I work with Audio, I have no real clue on how audio works on Linux, despite using it since Kernel 0.97...

What I have: I've got a machine with normal onboard audio IOs and a BT dongle. It is running Ubuntu Server.

What I want: I want it to take the analog signal from LineIn and forward this to a BT speaker linked to the BT dongle. This should preferably run like a service, so it autostarts when booting the server.

Any idea where to start, which programs and systems to look for?

Because you now did it to yourself.
