What is this? Found it in an old Star Wars advent calendar. Not sure if it's custom or official, and I will appreciate any good guesses.

This is a simple thing that has been bothering me for a while now. When you try to open a second "Computer" window (the place where you can see all your hard drives, cd drives, memory devices e.t.c) via start menue, you just get redirected to the one that is already open. Is there a way to prev...

The energy of a moving object is $E = mv^2\;.$ That is it increases with velocity squared. I walk at say 3 miles per hour, or lets round that down to 1 meter per second for a slow walk. I weigh less than $100~\mathrm{kg}\;,$ but lets just round that up to $100~\mathrm{ kg}$ for convenience (it i...

Do you say: Who is the last in the line? As far as I remember I have seen some objections to this phrase on the part of native speakers of English. I don't remember what exactly they didn't like about it but they didn't like something.

I was thinking about a function with infinitely many right inverses but I could not come up with anything. Does there exist a function with infinitely many right inverses?

This is the box of a LED spot I just bought. I'm wondering why the power consumption is measured in kWh/1000h and not simply in Watts. Edit: The labeling standard can be found here. (Guide for the application of the commision regulation (EU) No. 874/2012 with regard to energy labelling of ele...

I am finding the following moral problem, and possibly people with more experience could help me. One of my Master students (who recently finished his master studies) is applying for PhD positions. Despite my good scientific opinion about him (and his master thesis research), my personal opinio...

I know that I can use apt-get remove <package> to remove a program. But apt is a program itself. Could I use apt-get remove apt to remove it, or would it get confused part way through?

A character of my story is in the following situation: He is in the middle of a forest and has lost his way out. He wants to be sure to keep straight on and not to move in a circle. He has no compass, there is no sun and no stars, just diffuse light. A second person is with him, they have no spec...

1953 F-100 w/ 428 Cobra Jet FE motor. I want to spare my grill and avoid putting the condenser in front of the radiator. Plus, it's already a beast to cool in hot weather, and I live in hell. (It's hot here.) Any other locations for the condenser that you can suggest? Be creative! I'm open to an...

I have two text files. Each line represents a line in one language. I need to check if the alignment always fits. Therefore I need a program that displays both text files at the same time with line numbers. I tried diffuse, but that tries to align the files - if by accident two lines are equal, ...

I want a way to make a lot of different units without having to program stuff like moveTo and Attack actions more than once The way I see it, there are 2 ways I can do this. A single generic Unit class with flags that specifies what it can/can't do (then create instances in a static array and ...

I have this very simple test function that I'm using to figure out what's going on with const qualifier. int test(const int* dummy) { *dummy = 1; return 0; } This one throws me an error with GCC 4.8.3. Yet this one compiles: int test(const int* dummy) { *(char*)dummy = 1; return 0...

Using a LDR or Photoresistor, are they more sensitive to one color or wavelength compared to another? Or are they consistent with any light? Why?

Our world has easily observed year, month and day cycles. They and their multiples, such as decades or weeks, and fractions, such as seasons, hours, minutes, and seconds are easily available and used to synchronize and measure events. Seasons and daylight make timing actions highly important acti...

A topological space is a set $X$ and a collection $\Omega$ of subsets of $X$ such that: $\emptyset \in \Omega$ and $X \in \Omega$ The union of any collection of $\Omega$ is in $\Omega$ The intersection of any finite collection of sets in $\Omega$ is again in $\Omega$ My question is, is the se...

This has always bothered me. I'm talking about their encounter on Geonosis in Attack of the Clones. The whole scene can be seen here with the saber-hand-off in question at 1:35. After Obi-Wan is injured, he hands-off his lightsaber to Anakin who continues to fight Dooku with two sabers at once (...

If one aspired to a traditional, research-based academic career in a major university, would teaching for a few years at a community college (say, after the Master's) be damaging to one's CV? I'm worried that it would create a record of affiliation with a low-ranked university that would make peo...

Thanks in advance! Please let me know if I should provide more specific information, or if this is covered somewhere else. Short version: I am using a Frost King window insulation kit on a window. Can I skip the hairdryer step and still get a good amount of insulating effect? Long version: I ...

I have looked but haven't been able to find an answer to this question anywhere. Please link it if it has been asked somewhere else :) How could Draco Malfoy use a transfiguration spell and conjure a snake during the duelling club, the second year? From what I remember was conjuring something t...

I have a table with some numbers in it, such as \documentclass{article} \begin{document} \begin{tabular}{llll} 1 & 2 & 3 & 4 \\ 1 & 2 & 3 & 4 \\ 1 & 2 & 3 & 4 \\ 1 & 2 & 3 & 4 \\ 1 & 2 & 3 & 4 \end{tabular} \end{document} I would like to have a "background" for the table (I actually want to...

Does a spellcaster know when concentration ends on one of their spells? For example, when a wizard casts invisibility, that target is invisible until they attack or after one hour. So if the character attacks and the spell ends is the wizard aware that their spell that they are concentrating on ...
