The trip, should it go ahead, would mark Xi's first visit to the North   Korean capital since he came to power in 2012.     What is grammar about the "should" go first non-question sentence?
I'll be at my uncle's house just in case you need to reach me.      I'll be at my uncle's house should you need to reach me.   Could you tell me what is the difference between those?
how to pass objects between intents Is there a difference between "Alpha Helix" and "Alpha subunit"? I'm using the following command to embed images in my LaTeX document (which is then rendered as PDF)  \newcommand{\img}[4]{   \begin{figure}[!hbt]     \centering       \vspace{1ex}       \includegraphics[width=#2]{images/#1}       \caption[#4]{\label{img.#1} #3}     \vspace{1ex}   \end{figure} }   When creating a href to an image, the viewer jumps to the image caption instead of the top of the image. How do I change my \img command so it still puts the caption below the image but links to it jump to the image itself? I have a  repository which contains a number of subdirectories. Now I have found that one of the subdirectories is unrelated to the other and should be detached to a separate repository.  How can I do this while keeping the history of the files within the subdirectory?  I guess I could make a clone and remove the unwanted parts of each clone, but I suppose this would give me the complete tree when checking out an older revision etc. This might be acceptable, but I would prefer to be able to pretend that the two repositories doesn't have a shared history.  Just to make it clear, I have the following structure:  XYZ/     .git/     XY1/     ABC/     XY2/   But I would like this instead:  XYZ/     .git/     XY1/     XY2/ ABC/     .git/     ABC/ apt-get cannot connect to Ubuntu archives I just installed a fresh version of Ubuntu 19.10 today, and the first thing I decided to do was to install GNU Screen, using sudo apt-get install screen. my output was: Reading package lists...

If any extra information is required I'd be happy to edit it into the question. Show that $A \setminus ( B \setminus C ) \equiv ( A \setminus B) \cup ( A \cap C )$ Show that  $A \setminus ( B \setminus C ) \equiv ( A \setminus B) \cup ( A \cap C )$  This is an exercise I was trying to do ( not homework ) and I got stuck as follows:  Working from $A \setminus ( B \setminus C )$:  $x \in A \wedge x \notin ( B \setminus C )$ $x \in A \wedge ((x \in B \wedge x \in C) \vee (x \notin B \wedge x \in C) \vee (x \notin B \wedge x \notin C) )$  At this point I'm not sure how to proceed.  Working from the other side $ ( A \setminus B) \cup ( A \cap C ) $:  $ x \in ( A \setminus B) \cup ( A \cap C ) $  $ x \in ( A \setminus B) \vee x \in ( A \cap C ) $  $ ( x \in A \wedge x \notin B ) \vee ( x \in A \wedge x \notin C ) $  $ x \in A \wedge (x \notin B \vee x \notin C ) $  $ x \in A \wedge x \notin ( B \cap C ) $  $ A \setminus ( B \cap C ) $  I could also use some formating tips like how display logical not and how to get the lines to display properly without blank lines inbetween. :-) The formal solution of the time-dependent Schrödinger equation Consider the time-dependent  (or some equation in Schrödinger form) written down as $$ \tag 1 i \partial_{0} \Psi ~=~ \hat{ H}~ \Psi . $$ Usually, one likes to write that it has a formal solution of the form $$ \tag 2 \Psi (t) ~=~ \exp\left[-i \int \limits_{0}^{t} \hat{ H}(t^{\prime}) ~\mathrm dt^{\prime}\right]\Psi (0). $$ However, this form for the solution of $(1)$ is actually built by the method of successive approximations which actually returns a solution of the form $$ \tag 3 \Psi (t) ~=~ \hat{\mathrm T} \exp\left[-i \int \limits_{0}^{t} \hat{H}(t^{\prime})~\mathrm  dt^{\prime}\right]\Psi (0), \qquad t&gt;0, $$ where $\hat{\mathrm T}$ is the time-ordering operator.  It seems that $(3)$ doesn't coincide with $(2)$, but formally $(2)$ seems to be perfectly fine: it satisfies $(1)$ and the initial conditions. So where is the mistake? Does the stock market create any sort of value? Sorry if the below seems like a conspiracy theory. It probably is, but I probably don't understand something. (This has bugged me to no end as long as I can remember.)  Okay, so here is what I understand about the stock market?   The main way money enters the stock market is through investors investing and taking money out. The only other cash flow is in through dividends and out when businesses go public.   In a Ponzi scheme, there is usually some small source of income to hide the fact that it's a Ponzi scheme. Dividends are pretty insignificant. For the purposes of this question, we will only consider non-dividend stocks.  When you buy stock, it is claimed that you own a small portion of the company. This statement has no backing, as you cannot exchange your stock for the company's assets.   For example, if I bought $10 of Apple Stock early on, but it later went up to $399, I can't go to Apple and say "I own $399 of you, here you go it back, give me an iPhone." The only way to redeem this is to sell the stock to another investor (like a Ponzi Scheme.)  The stock market goes up only when more people invest in it. Although the stock market keeps tabs on Businesses, the profits of Businesses do not actually flow into the Stock Market.   In particular, if no one puts money in the stock market, it doesn't matter how good the businesses do.    Based on the above, it seems like the Stock Market has little to do with investing businesses to create growth, and primarily grows in a similar way to a Ponzi Scheme. (Some differences include that it is Stochastic (so when it collapses, it can be blamed on luck or the economy) and it has no top operator (similar to a Pyramid Scheme)).  Am I missing something? Does the stock market create value for investors? Background: I'm making a retro style game for both fun, and an unofficial contest.   I have bought a song, song X. However, I then found notation for song X, and all the instruments. So basically, it's a program recreating song X in a sense.  I took the notation, and used another program to make it sound like a chiptune does (just for the fun of it, and it sounds good :P). However, I would like to use this in my game. It's non-commercial, but is this allowed? I would've said yes, because I'm not actually using the original, copyrighted song.  I think the main point is can I:   Use the music with no reference to the author Use the music with a reference, since it's non-profit. Not use the music at all since the melody and rhythm is copyright. How to find correctly the .bib file? I have a .bib document called References.bib saved in the following directory: C:\Users\dvale\Documents\3_References\References.bib  This file contains this entry: @Article{Ballot2014,   author    = {Ballot, Andreas},   title     = {Diversity of cyanobacteria and cyanotoxins in {Hartbeespoort Dam, South Africa}},   journal   = {Marine and Freshwater Research},   year      = {2014},   volume    = {65},   number    = {2},   pages     = {175--189},   issn      = {1323-1650},   doi       = {10.1071/mf13153}, }  I created a document and cited this reference, however the citation is not appearing, apparently because the .bib file was not found. I'm using biber as bibliographic tool (if is important this information). \documentclass[12pt,a4paper]{article} \usepackage{biblatex} \addbibresource[location=remote]{C:/Users/dvale/Documentos/3_References/References.bib} \begin{document} Example \cite{Ballot2014} \printbibliography \end{document}  When I compile the bibliography (F8 in TeXstudio) the following error appears ERROR - Cannot find 'C:/Users/dvale/Documentos/3_References/References.bib'!  EDIT 1: I use JabRef to create my .bib files with UTF-8 encoding The .blg file has the following information in the notepad [0] Config.pm:312&gt; INFO - This is Biber 2.15 (beta) [0] Config.pm:315&gt; INFO - Logfile is 'MWE.blg' [105] biber-MSWIN64:330&gt; INFO - ===  [127] Biber.pm:415&gt; INFO - Reading 'MWE.bcf' [234] Biber.pm:952&gt; INFO - Found 1 citekeys in bib section 0 [251] Biber.pm:4334&gt; INFO - Processing section 0 [267] Biber.pm:4523&gt; INFO - Looking for bibtex format file 'C:/Users/dvale/Documentos/3_References/References.bib' for section 0 [502] Utils.pm:411&gt; ERROR - Cannot find 'C:/Users/dvale/Documentos/3_References/References.bib'! [502] Biber.pm:132&gt; INFO - ERRORS: 1 Check Constraint with Case Statement Say, teamA score is 368 (369 to win), and teamB is batting at 368 (or 366). One run (or 3 runs) will make them win. The batsman hits the ball for a six, so score is 374 (or 372) which is more than the required 369. Even then the runs are counted for the team and for the batsman.  Now, on the last ball, suppose the batsman did not hit a six, but ran for a single : teamB will win. Can the batsmen continue to run until the ball is dead ?  Why will they want this ? (A) If batsman is at 98 and wants to reach a century. (B) If batsman has a career total of 9998 and wants to reach 1000 runs. (C) If the batsman has a very high record strike rate, and wants to remain at that record strike rate. (D) In the championship, this is the last quarterfinal, &amp; even winning will put teamB equal to teamC, and the better runrate at the end of the quarterfinals will enable them to move to the semifinals. (E) Many similar situations can happen.  So coming back to the question : Do the laws of cricket allow running on the last ball, even after winning ?  In most of the matches I have seen, after winning, the batsmen do not even look where the ball is and start celebrating the win. If the rules did not allow them to run more, then fine. If the rules did allow it, then has there been any game where they did run more ? Javascript function to convert color names to hex codes My friend Evan,is griefing me.

I found some where that i can bypass the proxy by using putty software. Can you guide me how can I bypass proxy by that? I tried, but I was not able to do so. Kindly tell me some easy method to bypass proxy. I don't want to used websites like accesstoblockedsites.com. Does the universe have an edge/boundary/barrier? If yes, what is at the edge? My question related kind of to asking what the shape of the universe is. Say a hypothetical alien civilization built an faster-than-light spaceship. If they keep flying would they end up where they began? ie space itself is curved...or would they hit some invisible barrier? How to automatically add &raquo; (») to  elements using CSS? How can I determine the name of the Bash script file inside the script itself?  Like if my script is in file runme.sh, then how would I make it to display "You are running runme.sh" message without hardcoding that? I read this story 30+ years ago in grade school. A man crashes on an alien planet. He has a small amount of water and accidentally spills some, and the planet replicates it but it must destroy part of itself to do so.  The man then finds some stale crumbs in his pocket, puts them in a trough, and the planet replicates them as well, but it's disgusting to eat. The man eventually decides that his situation is hopeless, so he lays down to die on a table in a hot room and thinks he can at least give back to the planet some of the nutrients it sacrificed for him. He falls asleep, and when he awakens, he has been transformed into an alien creature that is perfectly suited and adapted to live on the planet without discomfort to himself or damage the planet.
