2018-11-15 16:00 Email krypteringskrav fra 1. jan 2019 
Datatilsynet taler om kryptering på transportlaget eller end-to-end kryptering.
Det har aldrig været en god ide at sende fortrolige eller følsomme oplysninger via email, uanset hvilken type kryptering man har på plads. Kryptering på transportlaget bør have været på plads hos alle rimelige leverandører for mange år siden og er derfor uinteressant at tale om.
Hvis din IT-leverandør forsøger at sælge dig en ekstra løsning i forbindelse med disse nye krav, bør du kraftigt overveje at skifte.
Teknisk set er det muligt at benytte NemID til end-to-end kryptering men hvis du nogensinde har haft brug for support hos DanID ved du allerede hvorfor det kan være en dårlig ide.
Jeg anbefaler kraftigt, at email ikke benyttes til følsomme oplysninger, men at der i stedet etableres et workflow der minimerer muligheden for brugerfejl, færre sikkerhedsfejl i softwaren og bedre sporing med dokumenter.
My friend has gotten really into conspiracy theories lately, and he has started to believe that there was a highly advanced civilization on earth, like as highly advanced as ours, more than 13k years ago, but supposedly since a meteor or some other event happened and wiped most humans out, we started over, and the only reason we know about some history sites with stones buildings, but no old sites of metal buildings or electronics is because those would have all decomposed while the stone structures wouldn't decompose
I keep telling him even if the metal mostly decomposed, we should still have some sort of evidence of really old scrap metal or something right?

Scientists are voting to redefine the kilogram using physical constants rather than the arbitrary block of metal we use now. Here's an article about it: https://www.vox.com/science-and-health/2018/11/14/18072368/kilogram-kibble-redefine-weight-science
From what I understand, this new method will allow us to generate "reference" kilogram masses by using fancy balances anywhere in the world. I'm confused how we can use the constant speed of light to do this. The speed of light in a vacuum is constant, but doesn't the time component change depending on the local gravity and speed? Wouldn't that mean that reference masses would vary slightly, depending on the gravity and the speed at that particular facility, according to general and special relativity? Is this canceled out somehow, or is it just so small that it's still an improvement in precision over what we have now?

Let’s assume we have an unmanned spacecraft going to alpha Centauri about 4.3 ly away.
Our spacecraft can go .99c instantly.
And our spacecraft recorded a video the entire trip, to the star and back to earth: about 8.6ly total.
Let’s assume time dilation accounts for 1 earth year for each second that ticks on the system clock of our spacecraft. That would mean that it still took 4.3 earth years for the spacecraft to reach alpha Centauri, but only 4.3 seconds on the spacecraft??
If the video was brought back to earth and watched on earth, would the video be 8.6 second? Or 8.6 years? Would the spacecraft clock tick 8.6 seconds or 8.6 years?
Sorry for the possibly badly written question, I have no idea how relativity works.
Like, if parents bring home their newborn, can the dog/cat smell the newborn and "know" that the baby came from the parents?
I've tried googling it, and a lot of what I've found is specifically about how to introduce your pets to your new baby/do animals know what a baby is, and while that's interesting, that's not quite what I'm looking for?
I assume that a human baby would, presumably, smell like whoever is holding them most often, but do humans have an inherent "smell", and is that passed on in a way that dogs/cats can understand to the best of their abilities?

I am imagining minecraft, so this is probably a stupid question. But if I went to my backyard and got a shovel, how far would I go before I hit stone? Or is there even stone under? Earth science in high school covered types of rocks and and layers n stuff, but doesn't tell us where things are.
Are the tectonic plates made of rock? The education system has failed me, please help
E: so from what I'm getting - my education on earth science sucked. I loved physics and biology (chemistry sucked), but my "earth science" class was just "here are types of rocks. Here are the planets, good luck". From what I understand- it varies, bedrock isnt under 60+meters of stone as some childhood video games led me to believe, but could be 10-40ft below dirt. I think in my area, there is clay under me (my dad dug 6' holes for fence posts, and only got thick red stuff [probably clay]).
Thank you for all the help, I was up late at night and semi delerious when I got on this thought path, but I appreciate you all taking the time to answer :)
2018-11-15 04:00 A recent news article states that a plasma's temperature, for self-sustaining fusion, needs to be around 100 million C - but the core of the Sun is only around 15 million C. Why does a plasma's temperature need to be so high for fusion to work? And why not for the Sun? [AskScience: Got Questions? Get Answers.]
The article in question is here: https://www.abc.net.au/news/2018-11-15/china-attempts-to-create-an-artificial-sun/10495536.
I get that the temperature must be high enough to generate a plasma, but to the best of my knowledge plasmas start forming in the 10,000 C range.
I'm confused with what happens during elastic electron collisions with a surface. An example of what I am talking about would be back-scattered electrons in an SEM. There are representations of this I have seen that shows an electron "sling-shotting" around the nuclei, but this is an incorrect representation because that would cause the electron to produce bremsstrahlung x-rays, thus the interaction would not be an elastic collision. I was told that the electron "bounces" off the nuclei like a ball bouncing off a wall, but that explanation does not satisfy me. What force repels the electron away from the nuclei? Is it just electrostatic forces? Would an electron getting that close to the nuclei violate the pauli exclusion principle?
If the tube it self Is cut and there is now a open tube that’s sitting in the sac, then the sperm would still come out but only into the sac wouldn’t it? And even is it was closed somehow, then wouldn’t a buildup of sperm cause a problem? Eventually an extremely high amount of pressure of the sperm would break through whatever closed the tube. And then you’d be back to the situation of having sperm floating in the sac.
In the cosmetics industry, more than 70% of personal soaps that are used today have sodium lauryl sulfate or sodium laureth sulfate as the main cleansing agent, but why is that the case? Lauric acid based soaps are often derived from tropical plant sources, like coconut and palm oils.
I have seen next to no information about the cleansing power or just the general properties of ethoxylated oleic and stearic based cleansers. Oleic acid is the primary acid that can be found in plenty of oils, like soybean, canola, olive etc. Stearic acid can be made from oleic acid by hydrogenation, turning it from an unsaturated to a saturated fatty acid, giving it more cleansing power. Wouldn't it be more economical and less consuming to use those fatty acids in soap making instead of lauric acid based soaps? And as a added question, why is there so little information on oleic based surfactants?
I've been reading about the history of the Dark Matter theory and the evidence for it due to galactic spin speeds.
The way it is phrased in many articles is "without dark matter the stars would spin away, and the galaxy would rip apart." I understand this, but wouldn't this simplistic version of the evidence be answered by simply increasing the mass of the Galactic Core?
My current understanding is that the stars don't just orbit faster than expected, but the Acceleration Curve (the amount the orbital speed decreases with distance from the center) is shallower than expected, i.e. stars distant from the center move too fast relative to stars near the center for any possible mass of the Galactic Core. Is that correct?
Finally, if the above is true, I find it hard to visualize. As a hypothetical, if dark matter were visible dust would that mean the Galaxy would be a big dust cloud with a few stars speckled in it and the whole thing would be rotating at a more constant speed because the gravitation of the giant dust cloud would offset the mass of the Galactic Core?
I guess I don't understand why having mass everywhere would make the whole thing spin faster unless the center is also more massive. If, for example, our solar system was filled with gas or dust, would we be orbiting the Sun at a noticeably different speed? I'd almost expect the opposite. Forgetting about friction, wouldn't the gas past the orbit of the Earth be slowing it's orbit down, not speeding it up?
If you wanted to design a spherical resonator cavity composed of free space (i.e. vacuum permittivity and permissivity), what would the radius need to be in order to exhibit infinite impedance to the 511 kEV photon? That is, assume that free space is an LC-circuit with capacitance per unit volume mu_0 and inductance per unit volume epsilon_0 on which a photon propagates with velocity 1/sqrt(mu_o epsilon_0) = c. You want to capture and freeze the photon in a spherical resonator cavity constructed of free space. What is the critical dimension of the radius of this resonator such that its characteristic frequency matches the 511 kEV photon (i.e. the photon with energy equal to the electron's rest mass)?

The GenZe 2.0 electric scooter is one of those rare vehicles that doesn’t just excite me, it actually makes me hopeful about the future of urban transportation. I’ve spent the last two months using it as my daily driver, and it has fundamentally changed the way I get around town.
After nearly 200 miles in the saddle, here are my thoughts on the GenZe 2.0 electric scooter.

I have basic understanding of quantum information theory, however I have no idea how is actual quantum processor hardware made.
Tangential question - what is best place to start looking for such information? For theoretical physics I usually start with Wikipedia and then slowly go through references and related articles, but this approach totally fails me when I want learn something about experimental physics.
Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary Science
Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...".
Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions.
The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists.
Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience.
If you would like to become a member of the AskScience panel, please refer to the information provided here.

Hello, I've been reading up on some of the functions of the endocannabinoid system, but I haven't found anything on all of the internet having to do something with CBD? I find plenty of experiments or scientific works talking about the influence of THC and it's effects, while with CBD I only find things such as it's healing effects and nothing about reaction time, nothing with the endocannabinoid system about reaction time either.
Excuse my grammar, simply an article would also be of great help :)
2018-11-14 20:00 Do you patch hardware-level backdoors in your OpenBSD systems? [OpenBSD]
Do you bother to patch the hardware-level backdoors in your OpenBSD systems, or do you only focus on hardening your OS, applications and network traffic? I'm new to OpenBSD and want to make the most secure system possible, but I don't want to waste my time with patching hardware-level backdoors if they are not avoidable these days.

2018-11-14 20:00 A classic idea in psychology is that brain is like a scientist - generating predictions about the world and testing them with information coming from the senses. But new models from theoretical neuroscience suggest the brain has some fixed 'hypotheses' that it cannot change. [Science]
Waymo waited till they hit 10 million miles before the official launch. I contend part of Waymo's cautious launch is simply gamesmanship. I believe they're intentionally setting the bar so high that it bleeds out smaller competitors. When Krafcik says: "this is a very long journey, and a very challenging technology" is he speaking to investors at Zoox? Is he saying, this is very difficult even for us with all our advantages, do you really want to invest billions more?
I used to think Waymo was allowing competitors to catch up by delaying the launch, however it might just be that Waymo's extending their lead by delaying the launch. It costs Waymo a lot less time and money to drive another million miles than it does for their competitors. If Waymo launches with 10 or 11 million miles, can GM launch with just 5 million?
