I use Linux on my computers since kernel 0.97. I use an Android phone, but just out of pure lazyness and disregard, and for nothing serious - I'm on the smallest flat I could get, and still use only 10% of it. Some years ago, I said "when i need a smartphone, I'll build one", and I actually built an Android-based system before I got my first smart phone.

    That's because American rail tracks have never been built for speed. Some time ago there was an article about a new (or completely rebuilt) track, and they were happy to save a few million on the project by building it in a way that limits the speed to 80-100mph, instead of spending just a few percent more that could have enabled 200mph for bullet trains.

    If they only had some that could bear the load of national traffic.

    In Europe, the security theater installed after 9/11 was a godsend for the trains. Suddenly, saving an hour by going by plane instead of bullet train didn't matter anymore if you had to waste hours waiting at the airport security queues.

    Grandpa Cooking. I watched his funeral on YT. They tried to keep the channel alive without him, but with losing the central figure...

    I'm sad that the kids lost him, he helped them a lot.

    I'm designing a new MOC for my NeoClassic Space Moonbase: A tracked dumper like the ones from https://www.ntdh.co.uk/ which I've seen at the Whitchurch channel breach, but, of course, "spacified" with a blue cabin and engine cabinet.

    Now I'm not the LEGO technic guy, and for the tread assembly, I've found the piece 32272 (Technic, Liftarm, Modified Bent Thick 1 x 9 (7 - 3)), which would make a for me perfect spacing to place the outermost gears. Sadly, this piece has axle holes instead of pin holes at the ends. So I could make a plain show piece where the tracks can't move as the axle with the gear can't turn.

    So, what is your opinion: Is a static model sitting on a display OK, or should I find ways to make the tread "spin", even though it will never move?

     

    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?

     

    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?
