Do eggs really need to be refrigerated? If so, how long can they last without refrigeration? Obviously eggs come out of the chicken at body temperature, so there must be some amount of time they can survive without spoilage.  I once attended a catering school in Hungary, and families there store eggs at room temperature for days with no (apparent) ill-effects, particularly in rural areas. But the idea seems anathema to almost everyone in the US.
I've read a lot of conflicting advice on whether it's advisable to store eggs in the refrigerator. The case against seems twofold: (1) that eggshells are porous, and eggs can take on unwelcome flavours, or even spoil faster in the fridge, and (2) that cooking with cold eggs can be problematic. But lots of people refrigerate eggs through perceived necessity.  Do eggs last longer in the fridge, and is the shelf life gain worth it? Or should I just stick them in the cupboard?
Status of B1/B2 visa after citizenship change? I have a valid B1/B2 visa valid to US till March 2019 on Indian passport, I changed my citizenship to Australian. Is my B1/B2 visa on Indian passport valid? Why do we get the same differential equations from both principles? Surely there is a fundamental connection between them? When written out, the two seem to have nothing in common.   $$\sum _i ( \mathbf F _i - \dot{\mathbf p}_i) \cdot \delta \mathbf r _i = 0$$  $$S[q(t)] = \int ^{t_2} _{t_1} \mathcal L (q,\dot{q},t)dt$$  After playing with d'Alembert's principle  we find that we can rewrite the whole thing as $$\sum _i \left[ \frac{d}{dt} \left( \frac{\partial T}{\partial \dot{q}_i} \right) - \frac{\partial T}{\partial q_i}-Q_i\right] \delta q_i$$  This can further be rewritten under certain conditions so we get the exact form of the E-L equation.   It seems to me that both ways of arriving at the result are fundamentally different.   A function must obey the E-L equations in order to minimize the action over a path, but when we look at the virtual work, it appears that they come from the fact that (quoting Goldstein) "particles in the system will be in equilibrium under a force equal to the actual force plus a 'reversed effective force'."  I think I understand the principle of stationary action, I can see how it leads to the E-L equations, but d'Alembert's Principle seems so arbitrary, I can't see any motivation for it. Sending packets captured with Wireshark How do I copy a file in Python?  I couldn't find anything under . Why is Sauron called "the Necromancer"? During the time period of The Hobbit, a character is mentioned called the Necromancer.  Radagast even (in the movie) specifically states that the Necromancer can "summon the spirits of the dead."  (It's been a while since I read the book so I don't know if this exact phrasing is used there, but given the name it seems reasonable.) This character is later revealed to be Sauron.  Since when can Sauron summon the spirits of the dead?  He can extend life ad infinitum, like Gollum's, for example, and he can twist people into half-alive monsters, like the Ringwraiths, and he himself seems impossible to kill so long as the One Ring remains, but I can't recall ever actually seeing him "summon" something that was once fully dead.  In fact, the only character I remember doing that was actually Aragorn, though he merely commanded them and didn't raise them himself.  Is this just an unfounded rumor about the power in Dol Guldur, some hushed-whisper nightmare that isn't actually an accurate description, or is there a reason he is called the Necromancer?  It seems like if Sauron could actually resurrect the dead, what little chance Middle Earth had of defeating his hordes would be long, long gone...

Where in the registry does Windows store with which program to open certain file types? After installing Adobe PDF reader, it opens files with the .PDF file extension. Ones' default web browser opens .html files and notepad opens .txt files, etc.  Where exactly in the registry are these filetype - program associations stored in the registry?

Space between 2 paths in Illustrator This is a Q&amp;A that I recently have figured out, so I have posted the answer below.

How do I fix this permanently? Is there a way to draw a Voronoi diagram with pgfplots? I want to draw a voronoi diagram with pgfplots, but sadly I cannot get it the way it should look like. I used the Matlab command to get the x and y coordinates and saved them as a dat-file. In that file I stored the x coordinates in the first column and the y coordinates in the second column.      Does anyone have an idea, how it could work?
