I believe it was on Reddit or somewhere else there was this community where each post was for survey // polling. The way it worked is below the post you would upvote if you want to answer this or that. So each comment you upvote for each possible answer.
This is great because it is anonymous.
I don’t want in the future a user telling me “okay, you have this opinion because you are this or that”.

Thanks for this. Anyway I notice I got zero upvote. So at this point, it doesn’t change much. (you got my upvote).

But I really do think it would be nice to have this ratio in society. I do believe woman are more peaceful. So I suppose it could make a more egalitarian world with less wars.

You may have heard of those societies where only woman can own houses and land. Those societies are very peaceful from documentaries I have watched.

Exactly 10 women for every man ideally here and everywhere else including in real life 😆

Seems like the plan, concerning these abuse, is to cut funding in half.

2023 SEPTEMBER 14 TECHNOLOGY
Slack Is Basically Facebook Now

Slack’s redesign suggests that keeping up with Slack is the only work worth doing.

“Oh,” I slacked my Atlantic colleagues earlier this week, beneath a screenshot of a pop-up note that Slack, the group-chat software we use, had presented to me moments earlier. “A fresh, more focused Slack,” it promised, or threatened. On my screen, the program’s interface was suddenly a Grimace-purple color. I sensed doom in this software update.

Slowly, over the days that followed, complaints about the new Slack started trickling into our chats. “folks I cannot handle this new version of slack and will be taking the rest of the month off,” one Atlantic staffer said. “I am reverting to sending physical memos on personal letterhead,” posted another. “all my slacks are: I hate the new slack,” slacked Adrienne LaFrance, the magazine’s executive editor. (Later on, she messaged me separately to see if I would write about Slack’s terrible new format.)

Global temperature record (section Ice cores (from 800,000 years before present))

This is amazing, if not the Americans, then maybe others will push the research forward.

Well, a lot of ice, a few strange birds and no oil. So, no big deal. /s

in other countries, in other times, when/where famine lurks, spilling and wasting food was almost a crime and small talk about people’s sensibilities was nothing more than a joke.

We are so far now in Western countries from those.

Lol, nice 😋,
Also it’s amazing how birds can effectively do that !

I want to apologize for posting that explosion image if maybe you were working on the space shuttle or close to people in there.

Many years ago I came to know an industry where accidental hydrogen explosions were to be described as “rapid oxidation events” (ROE) for insurance paperwork. Somehow writing the word “explosion” would have made insurance costs explode !
There are strong (& more) reasons to disbelive commercial transport projects involving hydrogen as energy source (energy vector).

Thanks for your time and explanations.

I agree the SRB was the start of the huge explosion that somehow involved liquid hydrogen. I was posting that example because I was replying to an example where it was gaseous hydrogen combustion and because for the plane in the post it is liquid hydrogen which is used.

I don’t mind talking to non-expert as long as they don’t believe they know what they don’t know and do not insist they know better when they don’t.

From your comment I don’t know what “ET” means but I suppose “SRB” is something like side booster rocket solid rocket booster (?) I am not an expert of the space shuttle so please tell me if it pleases you to do so.

Air Liquide is the supplyer of the hydrogen. You have green and blue hydrogen. One is produced with reformation and carbon capture while the other one is produced with electrolysis. So, if the electricity is from renewable then it’s technically zero emission.

A_A , 11 months ago to technology in World’s first crewed liquid hydrogen plane takes off

I agree…
( except for a small typo : it’s carbohydride or hydrocarbon )

LEL for Hydrogen: 4.0 (% in air)
UEL is 75 %
This is the most severe (wide range) for any fuel.

This is on top to hydrogen enbrittlement and low temperature enbrittlement of metals.

Good luck with the insurance fees for commercial flights.
