That is not only not right; it is not even wrong

Many classical email clients have the option to edit the senders address while composing the email. If the mail server does not allow this you usually get an error message on sending.

Trying to remember what i learned in history here, i hope i get at least most of it right:

• the political institutions of the Weimar republic were not as balanced and protected from interference as in other democracies
• many parties were against the existence of the Weimar Republic
• they differed a little in what they wanted instead though, ranging from reintroducing the monarchy with a few republican elements, to full fledged socialism
• the difference between the parties made finding compromises very difficult and often resulted in stalemates in the legislative, because of missing checks this did not affect the executive as much though
• especially the monarchists liked the idea of heaving a leader that can overrule the parliament if needed and so it was easy for Hitler to get them to agree that they would all be better off with him breaking the stalemate so to speak. So they formed a coalition
• see also https://en.wikipedia.org/wiki/Harzburg_Front
• Those parties also had no qualms with banning other parties just because they disagreed on something, which Hitler was very happy to do, starting with the communists and ending with a complete ban on forming political parties after every serious contender was eliminated

Do you know how many parties had members in the parliament of the Weimar Republic when Hitler was named Chancellor?
I learned in school – not sure if this part is entirely accurate but its an interesting idea anyway – that this situation was precisely why there is a ~5% of votes, lower barrier for parties sending representatives in many modern European democracies.

UDMH

At least that stuff is stable while in a tank. Imagine sitting next to tons of rocket grade hydrogen peroxide, slowly decomposing, just waiting for an excuse to go boom.

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).

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.)

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.
