I’ve been missing an alternative to Facebook that I can use for non-anonymous planning of events and communication in hobby groups etc. and I had never heard of any of the “Facebook-type” federated stuff before!

Now I just need to convince a bunch of people that this is viable to use without being the annoying guy…

Exactly! I mean… some reptiles eat eggs, so we could be talking about something that happened before our ancestors had developed the concept of an ass. I don’t think it’s far-fetched to think that eating eggs may be as old a concept as eggs themselves. In that case, the first egg-eaters evolved alongside the first egg-layers, and were eating proto-eggs before even the modern egg existed.

Imagine if zebras started evolving very tough placentas over time, and the foals started lying around in them for a couple days before popping out: Lions would keep eating newborn zebras, and no single lion generation would notice that they were slightly different from 1000 years prior. Give that development a million years or whatever and you now have egg-laying zebras and egg-eating lions!

I would go even further: Our primitive ancestors likely descended from proto-humans that descended from primates that were already foraging eggs. Some modern apes and other mammals eat eggs as well, we’ve likely been eating eggs since hundreds of thousands of years before the first human evolved.

In a sense, that line of though is interesting: When we think of “observing other animals eating something, and then deciding to eat it”, we’re almost implicitly forgetting that we are descendants of exactly those types of animals, that “just know” what is safe to eat, and that some of the knowledge we have about food is potentially passed down from even before the first primates evolved.

I’m here to say that if there’s snow, skis win on practicality. Almost every winter, there’s at least one day when you will have some people skiing to work in Oslo, a city of 700 000 inhabitants, with a metro system. Because when there’s 10 cm of snow in the streets, skis are the quickest and easiest way to get anywhere.

I have to admit: If you (semi-)regularly use floating point comparisons in programming, I don’t know why you would ever expect 0.1 + 0.2 == 0.3 to return true. It’s common practice to check abs(a - b) < tol, where tol is some small number, to the point that common unit-testing libraries have built-in methods like assertEqual(a, b, tol) specifically for checking whether floats are “equal”.

Possibly a poor translation from my side: I’m referring to the “head office” of the university, i.e. the group of people under the direct leadership of the principal, who have the highest administrative authority at the university.

A professor at my university tried that, but the students quite quickly made a huge fuss, got the principals office involved, and the universities lawyers informed said professor that what she was doing was illegal, and that she should stop before she got any more trouble. She stopped.

I really struggle to comprehend how you can debug hardware that is several light-hours away, let alone how you would proceed to split an OS (or whatever Voyager is running) into separate parts and then upload those parts to separate hunks of memory to make a functioning machine…

Also: What would they do if the code they uploaded was corrupted “in transmission”?

I have no idea about the differences in tolerances and reliability between “army grade” and “consumer grade” weapons, but I know that the MG3 is renowned for being extremely reliable in military context.

I’ve never even thought about trying a bump stock, but the idea that some of the energy that “should” be going into properly chambering the round instead goes to simulating automating fire, and that it therefore increases the risk of a misfeed or jam makes a lot of sense.

To be fair, the result of this calculation only depends on the area/volume ratio of the human. I used the specific cylinder, because humans are roughly cylindrical, and have a volume of roughly 100 L. The surface area of a regular human is probably a bit larger than that of a cylindrical one though.

I’m actually a chemist, thankyouverymuch

#Physics When There’s Too Many Electrons For The Physicists

;)

The math actually says that we might quite possibly get nuclear stuff. I checked because at first I intuitively thought the same thing as you.

Assuming

• cylindrical human, 2m tall, 25 cm diameter.
• air displaced from the point you teleport to is instantly moved to form a monolayer (1 molecule thick) on your surface.
• The displacement of air is adiabatic (no heat is transferred, which will be true if the displacement is instantaneous)

Volume of displaced air: ≈ 100L = 0.1m^3 At atmospheric conditions: ≈ 4 mol

Surface area of cylindrical human: ≈ 1.58 m^2 Diameter of nitrogen molecule (which is roughly the same as for an oxygen molecule) : ≈ 3 Å Volume of monolayer: ≈ 4.7e-10 m^3

Treating the air as an ideal gas (terrible approximation for this process) gives us a post-compression pressure of ≈ 45 PPa (you read that right: Peta-pascal) or 450 Gbar, and a temperature of roughly 650 000 K.

These conditions are definitely in the range where fusion might be possible (see: solar conditions). So to the people saying you are only “trying to science”, I would say I agree with your initial assessment.

I’m on my phone now, but I can run the numbers using something more accurate than ideal gas when I get my computer. However, this is so extreme that I don’t really think it will change anything.

Edit: We’ll just look at how densely packed the monolayer is. Our cylindrical person has an area of 1.58 m^2, which, assuming an optimally packed monolayer gives us about 48 micro Å^2 per particle, or an average inter-particle distance of about 3.9 milli Å. For reference, that means the average distance between molecules is about 0.1 % of the diameter of the molecules (roughly 3 Å) I think we can safely say that fusion is a possible or even likely outcome of this procedure.

I am now sitting on the wing of a plane that is about to take off. Gonna try to Tom Cruise it. Will post updates soon.

To be fair: If you live in the south, it doesn’t make much sense, but if you live a bit further north it’s the difference between getting up when the sun is a a reasonable place, or getting up in the middle of the night (winter) or the middle of the day (summer). I want it to be light out when I’m awake, not when it’s sleeping time.

Turns out it’s easier to adjust the clock than to say “work starts at 9 in the winter and at 8 in the summer”

This put words to thoughts and feelings I have had for a long time, but have not been able to express accurately. Thank you, well written.

Some languages - specifically Norwegian that I know of, don’t have separate words for “boyfriend” and “girlfriend”. In Norwegian we have the word “kjæreste” which can be directly translated to “dearest”. To me it always feels a little weird to use “boyfriend” or “girlfriend”, i guess the same could be true for other non-native english speakers.

If we’re able to make hydrocarbon-synthesis from CO2 efficient… we’re still going to need to source the hydrogen somewhere.

But if we do that using electrolysis (with renewables), and are able to create more energy efficient CO2 capturing processes, I could see synthetic hydrocarbons as a viable fuel option in the future. The thing is: They’re stupidly good at being stable, energy dense, energy carriers. We also have a lot of infrastructure in place to handle hydrocarbons already.

In principle, synthetic hydrocarbons could be part of a zero-emission cycle, where we capture CO2 and electrolyse hydrogen with renewable energy, and use the hydrocarbons as an energy carrier. But if we go that way, we’re definitely going to have to research efficient hydrogen production, and probably storage as well.

One of the advantages of hydrogen is that tanks and fuel cells can withstand a large number of “charging cycles” much better than batteries. Additionally, for ships, the amount of energy needed to move is so enormous that I fear we’ll have a hard time creating batteries that are feasible for long-distance shipping.

For short distance ferrying (including large, car carrying ferries) on the other hand, Norway has already implemented quite a few electric stretches. The major issue there is building the infrastructure to charge the ferries.
