Being associated with a SciFi community or Arqade is not a bad thing for my serious work-only profile, but it could be indeed an issue for people trying to hide association with a religious community due to the dark times that we are living on. I know that this question is similar to , but I'm posting this as  of Adam Lear Determine which circuits are parallel and which are in series I need to find the Equivalent Resistance across A and B.

So, there are lots of different versions of Unix out there: HP-UX, AIX, BSD, etc. Linux is considered a Unix clone rather than an implementation of Unix. Are all the "real" Unices actual descendants of the original? If not, what separates Linux from Unix? How do I create a Java string from the contents of a file? I've been using the idiom below for some time now. And it seems to be the most wide-spread, at least on the sites I've visited.  Is there a better/different way to read a file into a string in Java?  private String readFile(String file) throws IOException {     BufferedReader reader = new BufferedReader(new FileReader (file));     String         line = null;     StringBuilder  stringBuilder = new StringBuilder();     String         ls = System.getProperty("line.separator");      try {         while((line = reader.readLine()) != null) {             stringBuilder.append(line);             stringBuilder.append(ls);         }          return stringBuilder.toString();     } finally {         reader.close();     } } Convert a Bitmap to GrayScale in Android Is it mandatory to have published papers while applying for PhD? I've heard from people saying that while applying for PhD, you need to have past experience in researching something and should have international publications. I was like more concentrated towards practical experience and have't had any publications. If I am aspiring to do PhD and want to apply, it would be impossible if such a criteria exists! problems installing mathtools What would I do if I want to have a generic method that only accepts types that have overloaded an operator, for instance the subtraction operator. I tried using an interface as a constraint but interfaces can't have operator overloading.   What is the best way to achieve this? Money transfer from India to USA My daughter is a US Citizen.

If there is something more on the subject to make me understand, please advise. Thanks, Why don't the colonists wear spacesuits in Alien: Covenant? In the beginning of the Alien: Covenant movie, a group of colonists from the main ship make a landing on an unknown planet, which they found out accidentally after ship has been bombarded by an unknown wave from a star collapse and what bothers me, is that they don't wear any spacesuits, any protective gear, any air filter systems, just nothing.  Is that really the way future space expeditions gonna explore new possible planets presumed as possible habitable homes for humanity?  Every 5th grader knows, from the biology school lessons, that water, air, and even earth itself contains and gives life to a thousands of viruses, bacteria, and microorganisms.  You can breathe in bacteria, or virus, and be dead in a seconds.  Do film makers really suppose we will take it as realistic depiction of extraterrestrial expedition?   Reality check just screams out loud.  What do you think can be their motivation for such a decision? setting up apache2 webserver -- differences between behaviour within my intranet and outside Run a Windows Service as a console app What happens if I do not honor a futures contract? I have little knowledge about futures contracts. The recent negative price of crude oil spurred my curiosity about this stuff.   I read this post about .  According to this post, when I buy a futures contract, I enter into a contractual agreement to buy some commodity on some future date, and I only need to pay a 2% initial margin.   Suppose the price of the commodity does not fluctuate but I change my mind and decide not to buy the commodity at maturity. What punishment could be exerted on me?   I do not want the 2% initial margin back because that is a little money compared to the real value of the commodity. If there is no extra penalty, it would be unfair for the seller — imagine the seller transports 1000 barrels of crude oil to your front door and you say "I do not need it any more, please take it away, thank you!"  Update: I did more research about this and have more questions.  If I buy a futures contract at $10 and the price of the contract drops to -$37 at the last trading day, at which price should I buy the commodity at the delivery day, $10 or -$37?   There seems not just one contract I enter into when I buy a futures contract: the original futures contract between me and the seller of the commodity(or the exchange?), the contract between me and my brokerage, the contract between the brokerage and the exchange. I'm not clear about the exact entities of each contract and the obligations involved in each contract. The contracts seem contradictory with each other, e.g., my brokerage may forcefully sell my futures contract if my account balance is not enough, which will prevent me from fulfilling the obligations in the futures contract, i.e., receiving the commodity on future date.  If I(or an institutional trader) trade directly (not via a brokerage) with an exchange(does CME accept individual traders?), does the exchange have the rights to forcefully sell my contracts at the last trading day at any price or close my position at the settlement price(say -$37)? If the exchange does so thus letting me own $5,000M to it, is it more justice for me to sue the exchange rather than let the exchange sue me? If I could hold the position, the loss caused by my not executing the delivery/receipt of the commodity may be less than $5,000M. Of course, the loss will be determined by the court, not by the exchange according to the settlement price formed by itself or a few possible conspirators. Can there be only one extension to the factorial? Usually, when someone says something like $\left(\frac12\right)!$, they are probably referring to the Gamma function, which extends the factorial to any value of $x$.  The usual definition of the factorial is $x!=1\times2\times3\times\dots x$, but for $x\notin\mathbb{N}$, the Gamma function results in $x!=\int_0^\infty t^xe^{-t}dt$.  However, back a while ago, someone mentioned that there may be more than one way to define the factorial for non-integer arguments, and so, I wished to disprove that statement with some assumptions about the factorial function.    the factorial   is a  for $x\in\mathbb{C}$ except at $\mathbb{Z}_{&lt;0}$ because of singularities, which we will see later. is a monotone increasing function that is concave up for $x&gt;1$. satisfies the relation $x!=x(x-1)!$ and lastly $1!=1$     From $3$ and $4$, one can define $x!$ for $x\in\mathbb{N}$, and we can see that for negative integer arguments, the factorial is undefined.  We can also see that $0!=1$.  Since we assumed $2$, we should be able to sketch the factorial for $x&gt;1$, using our points found from $3,4$ as guidelines.  At the same time, when sketching the graph, we remember $1$, so there can be no jumps or gaps from one value of $x$ to the next.  Then we reapply $3$, correcting values for $x\in\mathbb{R}$, since all values of $x$ must satisfy this relationship.  Again, because of $1$, we must re-correct our graph, since having $3$ makes the derivative of $x!$ for $x\in\mathbb N$ undefined.  So, because of $1$ and $3$, I realized that there can only be one way to define the factorial for $x\in\mathbb R$.  Is my reasoning correct?  And can there be only one extension to the factorial?    Oh, and here is a  to how I almost differentiated the factorial only with a few assumptions, like that it is even possible to differentiate.  Putting that in mind, it could be possible to define the factorial with Taylor's theorem? When defining a method on a class in Python, it looks something like this:  class MyClass(object):     def __init__(self, x, y):         self.x = x         self.y = y   But in some other languages, such as C#, you have a reference to the object that the method is bound to with the "this" keyword without declaring it as an argument in the method prototype.    Was this an intentional language design decision in Python or are there some implementation details that require the passing of "self" as an argument? Can I make an ender portal on creative? I've updated Minecraft PE, and in the update notes it states that they've added the End. But when I made a new creative world and built a portal, it didn't work.  I've been looking online at tutorials, but cannot get the portal to open. So how do you create an Ender Portal? When should "farther" and "further" be used? Bug? LaTeX misparses nested optional arguments LaTeX seems to be having problems handling nested optional arguments. I've included a minimal code example that generates the error:  \documentclass[12pt,oneside]{book} \begin{document}  \newcommand{\termbad}[2][]{#2#1} \newcommand{\termgood}[2][]{#2#1}  \newcommand{\up}[1]{#1} \newcommand{\dd}[1][]{#1}  \termgood{\up{Tart}}{Pop} \termbad[\up{Tart}]{Pop}      \termgood{\dd[Tart]}{Pop} \termbad[{\dd[Tart]}]{Pop} %\termbad[\dd[Tart]]{Pop}   \end{document}   If you run this code, it works. If you remove the % in the second to last line, it fails with:  Runaway argument?  Tart{Pop} \par \par \end {document}  !File ended while scanning use of \dd.   After further tinkering, I have discovered the problem: LaTeX is reading the ] for the inner optional argument as the end of the outer optional argument and then passing a malformed argument in. So it is passing in \dd[Tart as the optional argument to \termbad instead of \dd[Tart].  This still feels like a bug to me. Nesting braces in arguments works, brackets should as well. The following are workarounds:   Enclose the inner optional argument in braces (as in the line before %). Redefine your inner function to require its argument instead of using optional arguments. Redefine your outer function to require its argument instead of using optional arguments.   Any one of the three works around the issue.
