Can I supply a device rated for 1A with 15A power supply?
Choosing power supply, how to get the voltage and current ratings?
Why didn't Dumbledore prevent the prosecution of Sirius Black? Dumbledore performed the Fidelius charm on the Potters, so he knew who the Secret-Keeper was1. That implies he knew not Sirius but Wormtail betrayed the Potters. Why didn't he prevent Sirius's conviction and suspect the explosion killing twelve Muggles was caused by Wormtail (and that Sirius cornered Wormtail instead of the other way around)?   1: Though in  it is said Dumbledore didn't know. I find it hard to believe the person casting the Fidelius charm doesn't know who the Secret-Keeper is. A coin with heads probability $p$ is flipped $n$ times. A "run" is a maximal sequence of consecutive flips that are all the same. For example, the sequence HTHHHTTH with $n=8$ has five runs, namely H, T, HHH, TT,H. Show that the expected number of runs is  $$1+2(n-1)p(1-p).$$  I have tried to use some generating function on this but calculus got pretty messy and didn't work.

Does any body have any idea? bash variables in for loop range I want to print list of numbers from 1 to 100 and I use a for loop like the following:  number=100 for num in {1..$number} do   echo $num done   When I execute the command it only prints {1..100} and not the list of number from 1 to 100. Attributive or Possessive noun: the Dell Company's staff. or the Dell Company staff? In the following is it better to use a possessive noun with an apostrophe or an attributive noun without an apostrophe?

Let $X$ be a smooth projective variety over $\mathbb{C}$, then the Neron-Severi group $NS(X)$ of $X$ is defined to be the Picard group of $X$ modulo algebraically equivalent relations.   On the other hand, by the exponential sequence, there is a first Chern class map  $$c_1: {\rm Pic}(X) \to H^2(X, \mathbb{Z}).$$ It is claimed that the image of $c_1$ coincides with $NS(X)$.   I want to know why this is true. Any suggestion or reference is greatly welcome! How to trigger workflow from button in O365 I created a script editor webpart.

How do you deal with a DateTime that should be able to contain an uninitialized value (equivalent to null)? I have a class which might have a DateTime property value set or not. I was thinking of initializing the property holder to DateTime.MinValue, which then could easily be checked. I guess this is a quite common question, how do you do that?

Acknowledgements outside of document environment How do I add an acknowledgements section (maybe not specifically \section) outside of (before) my document environment?  in my .cls, there is  \def\@acknowledge{} ... \def\acknowledge#1{\booltrue{@ack} \gdef\@acknowledge{#1}} ... \def\ackpage{ \chapter*{Acknowledgments} \@acknowledge \newpage }   but it seems that I find problems when I put newlines in the  \acknowledge{folks in here}  (see  ) Should players get a surprise attack by interrupting a villain's speech? Just before confrontations with the "boss" of a dungeon or adventure, I often like to ham it up a bit and let the BBEG-of-the-week gloat a bit about how brilliant their plan is, or what a thorn in the side the PCs have been, or about how the PCs will never win, etc. Usually this is pretty brief, but it sets the tone of the encounter, and generally allows the players a window to say anything they wanted to say before we start the final combat. It also gives the players a chance to ask questions in case they missed something about the plot and they'd like it cleared up in-game.  Usually this goes just fine, and the players seem to generally like it, but sometimes a player who doesn't quite fit the narrative-focused mindset of the rest of the party gets a little restless and throws the first punch. Again, usually this doesn't happen, but occasionally it does.  If a player decides to do this in a given speech, how should I respond? I've defaulted to making everyone roll initiative when a player says they attack in a situation like this. After all, I don't really want to reward the players for attacking in the middle of dialogue, since I (and most of the players) find the dialogue to be really fun, and it mostly exists for the players' benefit, anyway. Besides, when the villain finally attacks, they don't get a surprise round -- their attack just means everyone has to roll initiative.  On the other hand, I feel like the player who threw the first punch might feel a little cheated in not getting a free shot off. They might be trying to have a cool moment of emulating Han Solo, blasting the enemy when they're caught off-guard gloating. Since I make them roll initiative, though, I rob them of this moment and Greedo might get the first shot off, anyway.  So, in this situation, should the player who fires first get a surprise round, or am I handling it correctly in making everyone roll initiative?  5e is the relevant edition, here. Quoting the rules is nice, but I'll take a well-reasoned argument for one way of playing or the other over a strictly RAW answer. How to find out the terminal command of an application?
