As an example, I have written this sentence: "People are trying to stop them from doing this in other countries, such as the U.N." Should this have a period at the end?
I always stumble when using abbreviations in a sentence, as they inherently contain a period in them. How do I use a comma or a semicolon after an abbreviation? How about a period?  E.g. (This is an example of my quandary)
Is there a portable version of Chrome for Ubuntu? I've been exploring implementing Angular 2.0 in Salesforce custom pages and found that if I set showHeader=true in the VF page, I run into some issues.   It looks like including the header loads "sfdc/main.js", which defines the browser's Map() function without checking if one already exists. This removes some needed prototype functions that are native to ES5/6 such as "set" (needed in Angular 2) and "delete" (needed for an ES6-shim).   I've found that even including an ES5 shim before the ES6 one in attempts to restore some of these prototype methods does not work. If I set showHeader=false, "sfdc/main.js" is not loaded and everything works fine.   Is there a recommended way around this, or is it possible to update "sfdc/main.js" to conditionally define Map() if one does not already exist? It looks like it leaves out quite a few native functions supported in modern browsers.  Thanks I need to generate random numbers within a specified interval, [max;min].  Also, the random numbers should be uniformly distributed over the interval, not located to a particular point.  Currenly I am generating as:  for(int i=0; i&lt;6; i++) {     DWORD random = rand()%(max-min+1) + min; }   From my tests, random numbers are generated around one point only.  Example min = 3604607; max = 7654607;   Random numbers generated:  3631594 3609293 3630000 3628441 3636376 3621404   From answers below: OK, RAND_MAX is 32767. I am on C++ Windows platform. Is there any other method to generate random numbers with a uniform distribution? Database schema documentation for the public data dump and SEDE AWS dynamodb support for "R" programming language How to create a database directory structure for MySQL? I'm writing my thesis using MiKTeX and WinEdt 9 for Windows. I write the different chapters individually, and then I have a "masterfille" with the documentclass "report" where I use the command "input" to load the individual chapters. In other words there is only a preamble in the "masterfile".  I have a very general problem which is the following: No matter what kind of mistake I do whatsoever, I will first receive the correct error message, say I forgot to end a table or something (it really does not matter). If I correct this mistake and try to recompile without using the option "Erase Output Files" in Winedt, I will always and very quickly receive a new error message, often containing a mysterious "Undefined control sequence". Having to do this every time and to recompile plus run the Biber (L+B+L+L+D) is very time consuming, since the document is very large. Any ideas what the problem could be? Here is the preamble of my "masterfile" (I am probably including irrelevant information, sorry for that):   \documentclass[12]{report} \setcounter{tocdepth}{2} \usepackage{layout} \setlength{\voffset}{-0.75in} \setlength{\headsep}{5pt} \usepackage[utf8]{inputenc} \usepackage[english]{babel} \usepackage{csquotes} \usepackage{authblk} \usepackage [T1]{fontenc} \usepackage[backend=biber, style=authoryear-comp]{biblatex} \usepackage{xyling} \usepackage[super]{nth} \usepackage{xspace} \usepackage{cgloss4e} \usepackage{abstract} \usepackage{array} \usepackage{multirow} \usepackage{hyperref} \usepackage{xr} \usepackage{gb4e} \noautomath  \let\eachwordone\itshape   \makeatletter \pretocmd{\@footnotetext}{     \@noftnotefalse\setcounter{fnx}{0}%     \renewcommand{\thexnumi}{\roman{xnumi}}     }{}{} \apptocmd{\@footnotetext}{     \@noftnotetrue     \renewcommand{\thexnumi}{\arabic{xnumi}}     }{}{} \@ifpackageloaded{bidi}{% \pretocmd{\@LTRfootnotetext}{     \@noftnotefalse\setcounter{fnx}{0}%     \renewcommand{\thexnumi}{\roman{xnumi}}     }{}{} \apptocmd{\@LTRfootnotetext}{     \@noftnotetrue     \renewcommand{\thexnumi}{\arabic{xnumi}}     }{}{} } \makeatother     \addbibresource{ref.bib}    \title{The origins of Old Romance V2: A comparative study of Late Latin, Old French and Middle High German} \author{XXX} \date{\today}   \begin{document}  \tableofcontents   \chapter{Old French} \input{chapters/OldFrench2}  \printbibliography  \end{document} Packages: graphics vs graphicx Different websites suggest using one of those two packages.  \usepackage{graphicx} \usepackage{graphics}   What are differences between them? Which is better? OS X: Blurry Beamer presentations on Sierra / High Sierra Since OS X 10.12 (Sierra), the built-in Preview, but also many other PDF Viewers on OS X (such as Skim) show a number of problems, among them the following rendering issue:   The page is first rendered in low-res  with blurry text and graphics. About one second (!) later, the page is rendered in high fidelity. The display "wobbles", as text and graphics on the high-fidelity page is about one or two pixels up.   Example code:  \documentclass{beamer} \begin{document} \begin{frame}{Duke says}   \begin{itemize}   \item&lt;+-&gt; It don't mean a thing, if it ain't got that swing         \item&lt;+-&gt; (doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah)         \item&lt;+-&gt; It don't mean a thing all you got to do is sing         \item&lt;+-&gt; (doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah, doo-ah)  \end{itemize}  \end{frame}  \end{document}   While one may consider this acceptable when reading documents on screen, this is a show stopper for presenting beamer presentations with animations. The low-res display and wobbling makes the audience sick, while the 1 second rendering time makes PDF-based animations impossible.  So I am looking for a PDF Viewer for OS X that does not suffer this problems, but that a suitable for presenting beamer-based slide shows. Requirements:   page-wise full-screen/presenting mode with just the page and nothing else on the screen crisp and high-fidelity display quick rendering time   Unfortunately, the root of the problem is in Apple's own PDFKit library that is the base for most PDF viewers on OS X. So I am looking for PDF viewers that are not based on PDFKit, but fulfil the requirements above.  I am aware, of course, of Acrobat Reader DC. However, I do not particularly like its font rendering (Req 2) and I would also prefer something more light weight. I also have PDFExpert, which also is not PDFKit-based, however, does not support a presenting mode (Req 1). Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE) Analogue of spherical coordinates in $n$-dimensions What's the analogue to spherical coordinates in $n$-dimensions? For example, for $n=2$ the analogue are polar coordinates $r,\theta$, which are related to the Cartesian coordinates $x_1,x_2$ by  $$x_1=r \cos  \theta$$ $$x_2=r \sin  \theta$$  For $n=3$, the analogue would be the ordinary spherical coordinates $r,\theta ,\varphi$, related to the Cartesian coordinates $x_1,x_2,x_3$ by  $$x_1=r \sin  \theta  \cos  \varphi$$ $$x_2=r \sin  \theta  \sin  \varphi$$ $$x_3=r \cos  \theta$$  So these are my questions: Is there an analogue, or several, to spherical coordinates in $n$-dimensions for $n&gt;3$? If there are such analogues, what are they and how are they related to the Cartesian coordinates? Thanks. My interest in Blender comes from wanting to use it to model physical structures and produce architectural drawings; what I have so far is really impressive, but there doesn't seem to be too much information about my particular interest.   Are there any (Blender-) resources that would be particularly useful for architects? E.g. packages of standard 'elements' like windows, doors, roofs or whatever, or perhaps a discussion group specifically for architects? factorization of a^n+1? I'm trying to prove that $a^n+1$ can only be prime if $n$ is a power of $2$. Is there a general factorization of $a^n+1$? I just watched a TV show and the guy says:     I ain't trying to fight with nobody with a baby.   So here, I can't understand the "nobody" since it make no sense to me, but it sounds like anybody, and if it's "I ain't trying to fight with anybody with a baby." that makes sense to me. I’ve recently purchased a new Mac Mini, and I’ve been importing my old pictures into the Photos app.  I want to have these photos backed up to iCloud, along with the photos currently on my iPad. I then want everything synced to my Mac Mini, but not to my iPad, which has limited storage capacity.  Is it possible to have the Mac Mini and iPad set up to backup to iCloud, but only download backed-up photos to the desktop? Why is there this strange contradiction between the language of logic and that of set theory? In standard probability theory events are represented by sets consisting of elementary events. Consider two events for which (as sets) $A \subset B$. If an elementary event $x \in A$ takes places then we say that $B$ takes place as well. Since $A \subset B$, $x \in A$ implies that $B$ takes place too.  It seems that when for sets (representing events) $$A \subset B$$ $$then \ A \ implies \ B .$$  On the other hand, if we use the language of logic for the events then $$A \supset B$$ $$ \ means\  that \ A\  implies\ B .$$  Why is this strange virtual contradiction between the language of sets and the language of logic?  (In order to avoid down votes and unplesant comments I reveal that I happen to know that the true translation of the sentence $A \supset B$ of logic to the language of sets (representing events) is $\overline{A \cap \overline B}$.) Plot Summary/Details  A human spacecraft lands on an alien world.  I'm not sure if they are exploring, or touched down for repairs. The world is a foreboding place, and home to a vicious predator that somewhat resembles a panther, or other big terrestrial cat. The creature is quite cunning, and ambushes several crewmen when they are scouting the planet or doing some other activity that would have them isolated and away from the ship. It sticks in my mind the creature is very strong, and able to bite through the heavy spacesuits the men wear with ease.  The creature has an unusual nutritional requirement of some sort. As such, it doesn't eat its victims, but somehow drains them of a particular element or chemical substance. I can't remember what it is, though I think it had something to do with the skeletal structure of the men. Calcium, maybe?  I have only very general recollections of how the story ends/is resolved. The humans become aware of the threat, and I believe they ultimately slay the beast. I can't recall anything more specific than that, unfortunately.  Timeframe of Publication  This one is old, I'm sure of that. I can remember the writing style and some of the descriptions being very "old school" - spacemen, rocketship, that sort of thing. Almost like something you'd see in an old sci-fi movie serial, to use a film analogy. If I had to guess, I'd say 1950's at the latest. I want to make some changes to Windows that require using the Group Policy Editor (gpedit.msc).  Unfortunately the Group Policy Editor is not included with the Starter Edition, Home and Home Premium editions of Windows.  How can I install it? Why is wine made 'from' grapes, but tables are made 'of' wood? (1) Wine is an alcoholic beverage made from fermented grapes or other fruits. (Wikipedia) (2) Tables were made of marble or wood and metal (typically bronze or silver alloys), sometimes with richly ornate legs. (Wikipedia)  Why is 'from' used in (1), whereas 'of' is used  in (2)? Is it a stylistic choice whether to use 'of' or 'from'? Or, in case of chemical changing, differently from changing in shape only, 'from' is preferable? Can I share my usb keyboard between two computers I love my Filco keyboard, I use it as primary keyboard for my Lenovo thinkpad all time. Now Im moving into the mac world and wonder:  is it possible to split my USB keyboard between two USB ports, ie one at my lenovo and one at my new iMac.   I was thinking that maybe there exists some kind of box with a switch to decide which port should receive the input, or preferable it would be possible to switch between the two via a keyboard shortcut.
