That is probably inspired by EN IEC 81346-2 where “X” indicates a connector of some kind and the numbers following the X identify the connector and the relative position on the connector (for connectors with multiple contacts).

ah ok i mistunderstood what the group head is. if they are both permanently in contact with the water in the boiler then it would depend a lot on the water quality. Water with only a little conductivity (<100µS/cm) would not be a problem for pure aluminium or most alloys, since the aluminium would passivate much quicker than the corrosion could dig into it.
i would assume that a vessel made for boiling water is made of a highly corrosion resistant alloy but i can not know for sure.
but that only happens while there is water there, right? so given the limited amount of contact time i think this is not a concern. aluminum has a great capacity for self-passivation too, at least the typical alloys do.
Do you mean oldest as in invented the longest time ago or oldest as in that specific technological artefact that i use is the oldest one i have?
For the first one i guess cooking?
For the second one its definitely my microwave oven, made in 1991.
expensive pharmaceuticals
antiretroviral meds are getting very cheap though, so not sure if that is really a valid point anymore. https://en.wikipedia.org/wiki/Cost_of_HIV_treatment
There is a limit on the spacing of the colour bands though. If you want colours then you have to hit the spots where the correct phosphors are and this limits the usable resolution.
So it still uses a MSDOS partition table, interesting. This usually only happens on systems that do not support EFI at all.
Is your BIOS and main board fairly old per chance?
Ok, that looks like a fairly standard setup. I guess taking a look at the boot loader itself would be the next step. When you see the Debian bootloader you could try pressing ‘e’ to view what commands it uses internally to boot. The lines starting with “linux” and “initrd” would be most interesting.
Hi, it would be useful to know what kind of device you are installing on. For a laptop the model and make would be especially useful. If it is a PC then the drive configuration would be interesting (what kind of drive, how many etc.)
They confused potassium and phosphate in the text.
So, i read the “Red Mars” trilogy. I also keep up with research into the Martian atmosphere, its soil and geology.
My take is that all of this is still a pipe dream as much as it was 30 years ago when we did not know many of these things.
People don’t want to see just how hostile Mars is to life. They pick a couple of the most obvious problems (e.g. radiation, no liquid water, no oxygen) and then they look for the first solution that seems viable and then declare Mars somehow liveable because look we can just implement those things.
But they are completely ignoring that: none of these proposed solutions have been implemented at scale yet, at least not outside of earth’ atmosphere, there are hundreds of other known problems that often just don’t make it to the head lines because they don’t look that interesting or threatening (example: dust is suuuuper deadly on Mars, probably even worse than moon dust) and many problems will undoubtedly only become obvious once living beings are on the surface of Mars.
I am glad that there is hard sci-fi dealing with some of these problems in very optimistic ways, because we should try to better our understanding of them and not just give up, but we also should not have any illusions about how hard this task is and that this can take centuries of work.
Most modern operating systems randomize the MAC.
[citation needed]
having the option to randomize the MAC is not the same as actually doing that. There are also a few downsides to random MACs, like captive portals not remembering you on public WiFis.
Palladium
since when is Palladium a REE?
You mean server? If so, the server is also open source
That is what i meant. It is OSS but not FOSS because you need a key to start it.
Bitwarden has a FOSS client app and FOSS server apps exist (though the default service is not FOSS).
Syncing 2FA keys brings the danger with it that you accidentally sync the key to the device that is used for the first factor thus making it not 2FA anymore.
trains are actually one of the examples where you can get away with lower energy dense fuels, like methanol, ammonia or even compressed hydrogen. sure the range will go down, but for many connections this will not matter that much because it will still be possible to go 1000km with one tank if needed.
If they are all installed in the same wine prefix you could back up everything in one go by archiving the “.wine” folder in your home. that will include all applications installed in wine and all settings for those applications.
if you want to separate them into one archive per app you should look into wine prefixes, otherwise you would need to identify every folder a given app created during installation and archive those together manually, which can be very tedious.

basically since around the 1960s bombers dont need to “drop” bombs anymore. They only designate the target and the FCS drops the bombs.
