A lot of the large image sizes are down to badly written Dockerfiles - most examples show the basics which become the "standard" & you get bad images.
However with some simply care & the use of stages you can keep the image size down to a minimum.
I do that with my builds, e.g. use debian as a base, then a stage adding gcc or other compilers, then a stage to do the build & install into a custom directory then a final stage extending the base (no gcc/sources) & copy the compiled version into the destination.
I prefer alpine when needed as it's far smaller but sometimes have to use debian as a base depending on the project.
As you I had some exposure to Photoshop in the past so some concepts like Layers came naturally to me when I started using GIMP 20 years ago.
Some tasks I need to lookup but those are the odd ones when I want some special effect or a task I rarely do.
Most normal tasks I just get on with it
I got one of these a couple of months ago, mainly as I'm moving my home office indoors & needed something like this to answer the door (i.e. camera not just a dumb door bell).
Anyhow, the thing is it had a warning inside the box about this exact problem & not to mix the screws up.
The security screws (which they provided the appropriate tool) is to attach it to the mounting thats screwed to the wall so it's difficult for someone to nick the door bell.
The warning clearly stated the overheating problem as the wood screws could "puncture the battery".
All morning I've seen people complain about the lack of USB3... totally ignoring that on the PI4B the USB3 is actually hogging the sole PCIe channel - some have hacked their pi's removing the controller to get at the PCIe.
Unlike the earlier dev boards, the new one allows existing hat's with it (one of my gripes with the old ones) but again some complaining about that.
It'll be interesting to see how one of these compares with the 4B & earlier CM models, I've just got to wait now until early/mid November for mine to arrive
Any 3d printer can catch fire, which is why they shouldn't be left unattended.
Remember, 3D printers run at high temperatures, I'm usually running the extruder anywhere between 180C & 200C
All you need is either a head crash or the filament to fail to extrude so it builds up as a blob around the nozzle & it will overheat. I've seen pics of print heads encased in a plastic cocoon which effectively needed them replacing, but if left longer could have been more serious.
Whenever I use my printer I'm always around & can literally pull the plug if things get serious.
RetroManCave did an unboxing of a Gateway CRT last week (I'm a patron so saw it before the public release yesterday) on his channel so there are some unopened stuff out there - here's at the point showing the classic cow box with an unusual for them black crt https://www.youtube.com/watch?v=TCQuUwHH45w&t=969
I do remember Gateway back in the 90's - was working in local government back then & Gateway was out supplier for a few years so saw hundreds of those machines. Some of their tower cases had an interesting design where you could convert to a desktop simply by moving the logo - there was no difference in the design between the two other than the logo
I consume a lot of those API's from TfL, National Rail & Network Rail & it's quite normal for those feeds to contain data not for public consumption, even though the feeds are freely available.
Normally that information isn't to be presented to the public mainly to stop confusion - i.e. for NRE you can get a platform number for a train but it's suppressed so you shouldn't show it - mainly to stop people crowding on a platform before it's known the train will actually go there - e.g. late platform change. Busy stations can also suppress them again for crowd control.
The TfL one you can get from https://api.tfl.gov.uk/
They never did archive images back then so a lot of my early stuff is now gone, although some text is still there, e.g. http://web.archive.org/web/19970821205517/http://maidast.demon.co.uk/finder/postgres/index.html
Ah those were the days when you only had a text editor to create anything...
I had the ICF-SW100 when it first came out & was a brilliant little world band radio - up until I lent it to my father & broke it. Gah.
These days I have an Eton G3 which is bigger but has similar battery life & slightly better SW coverage.
In reserve there's the emergency radio that has a manual charger (literally a handle you turn to charge it).
In both cases no way would DAB work & around here DAB signal is very poor
It must be a cloud thing as most Docker installations have their API sockets as a unix socket, so it appears as a file in the host's filesystem & as such isn't accessible from any network interface.
Instructions on how to expose the socket on the network is out there but even Docker's documentation states why that's a bad idea.
So for them to be exposed it's either someones done that manually or someone's provider has exposed the API socket without any appropriate Firewall rules against them
I did the same thing back in the 90's when it was the original StarOffice (before Sun bought them & open sourced it as OpenOffice & hence before the fork to Libre).
I had back then users saying their Excel files were corrupt so I'd load it into my copy of Star, resave, hand it back & it worked for them - it was a life saver
Reading the press release fully it's not in the crew area, that beige box in the articles photo is it.
"CryptIC measures just 10x10x10 cm."
“A major part of the experiment relies on a standard Raspberry Pi Zero computer,” adds Emmanuel. “This cheap hardware is more or less flying exactly as we bought it; the only difference is it has had to be covered with a plastic ‘conformal’ coating, to fulfil standard ISS safety requirements.”
It does have solar panels, batteries are for when it's got the Earth between it & the Sun & they wouldn't have lasted the 3 weeks or so since launch otherwise.
The momentum wheel is for attitude control. Can't use gas jets etc as there's no room for fuel & that could affect the sails as well.
Now it's deployed the next year is to attempt to change it's orbit using just photons from the sail. The momentum wheel will be used to tack, just like a traditional wind sail - so when it's orbit takes it towards the sun it's edge on so it has no effect & when going away from the sun it's full on to get the full benefit of the photons.
Going by this description of what happened the 3d printed components of the Super Draco actually survived - it was a lump of fuel that hit a non-return valve that then blew the poor thin to bits that caused a fire (burning the Titanium piping at that point)

The thing is, this is why they test spacecraft & they used the already flown hardware because they wanted to know how it would cope when it's reused,
It's good this happened as they know what went wrong & they have a fix - better than having a "bag of mostly water" (STTNG reference there) on board when it failed.
You can still get charged for that:
Every person . . . who is drunk while in charge on any highway or other public place of any carriage, horse, cattle, or steam engine, or who is drunk
so you can lose your license when drunk whilst being taken home by your cow

Those who've spent any time over here in the UK know's what Bollocks means but most don't.
Hence why you have Wilma Flintstone say it in an episode & get away with it (Channel 4 broadcasted that episode specifically for that 1 line), or at the end of the film version of Hitchikers Guide to the Galaxy you have one of the mice say "Oh bollocks!" - again got away with it as the American's involved didn't know ;-)
Not sure why the subheadline says from Network Rail when he's from Go Ahead Group - i.e. they who runs Thameslink Southern & Southeastern.
As someone quoted me on Twitter earlier this morning: "From one **show to another, Seems appropriate", more so when dealing with Crapita
I use alpine for most of my Docker containers due to it's small footprint - ~5MB for the base. Compare that to the basic Debian or Ubuntu images that ends up a big saving if all you want to run is some small app & none of the cruft.
I've not used Alpine on a standalone machine, but will be trying this one out, could be a good alternative for my cluster
