Will there ever be a full english translation of the Codex Gigas compiled all in one book?

How true is the assertion that most slaves in history were, in fact, white? Period: antiquity, location: middle east.

I'm not exactly sure what the claim really is - either that numerically most slaves were caucasian, either the enslavement was the most prolonged, or as a % of a population, it was the most significant.

Is there any truth to any variant on this claim?

What was it that there was widespread rationing during the world wars? Presumably the food supply was damaged, but how? Was it that farmers went to the front lines, that distribution networks were destroyed, that farms were burned, that supply convoys got attacked?

I have read on various places online that it is considered one of the most inaccurate film depictions ever made, but most of the qualms come from Wallace's love life and the fact that he wore a kilt. That being said, is the rest of the overall story really that marred? I am mainly interested in learning about the battles depicted in the film and the overall representation of Wallace and what he stood for.

For the purposes of this question I want to focus on serious daily sugar consumption. For that reason, I'm only interested in the consumption of semi refined sugars like honey and date syrup in those times, places and social classes where people consumed those things in large quantities regularly (as opposed to just at special celebrations). Has an increase in sugar consumption around the invention and spread of things like refined sugar or increased production of honey, dates etc been historically linked to changes in health measures like life expectancy, infant mortality etc? How do these changes compare to the introduction of other unhealthy products, like the introduction of tabacco to Europe or the popularization of opium for instance?

When I was in elementary grades [US public schools] we were taught that Hitler's body had been discovered in Berlin after the German surrender in WWII, but it was unclear how he had died.

When we studied WWII in more depth in high school, we were taught that "nobody knows" what happened to Hitler, and the teacher cited "unconfirmed reports" that he had escaped to South America. I'm an old fart, so this was in the 1970s, about the time that The Boys from Brazil was a hit movie.

Wikipedia says Hitler committed suicide by shooting himself, but the footnoted sources are decades delayed (books published in 1980 and 1995), and I'm wondering how reliably anyone could "know" that he shot himself. As I understand this version of events, only he and his wife were present at the end.

So I ask, do we actually know how Adolf Hitler died?

I'm interested in this subject, and I thought of asking here, since there might be other people who's interested aswell. I also like to study the most direct sources I can get to, because of many reasons. Any ideas?

The most direct I can think of is diaries from the pilots, or books written during the war with specs of the airplanes.

EDIT:
To make it a bit more clear, I'm searching to know things such as how they worked in war, and some basic technical specifications.
