There's a person named Khushwant Singh in a story. He and his grandmother are friends. There's a question asked in my book: What is the 'turning point' in the story? And my answer begins something like this: 'The turning point' in the lesson refers to the turning point in Khushwant Singh's and his grandmother's friendship. Now here's where I get confused. Did I use the apostrophes properly? If I didn't use it properly, how should I use it properly?
Which option is grammatical?        There will be readings from Nikki Giovanni’s and Alice Walker’s writings.   There will be readings from Nikki Giovanni and Alice Walker's writings.      Saying it out loud the latter sounds right, but looking at it the former looks better.
Shell script throws a not found error when run from a sh file. But if entered manually the commands work I'm trying to use the following script to generate a sitemap for my website. When I run it as sh thsitemap.sh I get an error like this and creates an empty sitemap.xml file:  thsitemap.sh: 22: thsitemap.sh: [[: not found thsitemap.sh: 42: thsitemap.sh: [[: not found thsitemap.sh: 50: thsitemap.sh: Syntax error: "(" unexpected   But as the same user root when I manually copy and paste these lines on the terminal, it works without any error and the sitemap.xml file have all the urls. What's the problem? How can I fix this?  #!/bin/bash ############################################## # modified version of original http://media-glass.es/ghost-sitemaps/ # for ghost.centminmod.com # http://ghost.centminmod.com/ghost-sitemap-generator/ ############################################## url="techhamlet.com" webroot='/home/leafh8kfns/techhamlet.com' path="${webroot}/sitemap.xml" user='leafh8kfns'       # web server user group='leafh8kfns'      # web server group  debug='n' # disable debug mode with debug='n' ############################################## date=`date +'%FT%k:%M:%S+00:00'` freq="daily" prio="0.5" reject='.rss, .gif, .png, .jpg, .css, .js, .txt, .ico, .eot, .woff, .ttf, .svg, .txt' ############################################## # create sitemap.xml file if it doesn't exist and give it same permissions # as nginx server user/group if [[ ! -f "$path" ]]; then     touch $path     chown ${user}:${group} $path fi  # check for robots.txt defined Sitemap directive # if doesn't exist add one # https://support.google.com/webmasters/answer/183669 if [ -f "${webroot}/robots.txt" ]; then SITEMAPCHECK=$(grep 'Sitemap:' ${webroot}/robots.txt)     if [ -z "$SITEMAPCHECK" ]; then     echo "Sitemap: http://${url}/sitemap.xml" &gt;&gt; ${webroot}/robots.txt     fi fi ############################################## echo "" &gt; $path  # grab list of site urls list=`wget -r --delete-after $url --reject=${reject} 2&gt;&amp;1 |grep "\-\-"  |grep http | grep -v 'normalize\.css' | awk '{ print $3 }'`  if [[ "$debug" = [yY] ]]; then     echo "------------------------------------------------------"     echo "Following list of urls will be submitted to Google"     echo $list     echo "------------------------------------------------------" fi  # put list into an array array=($list)  echo "------------------------------------------------------" echo ${#array[@]} "pages detected for $url"  echo "------------------------------------------------------"  # formatted properly according to # https://support.google.com/webmasters/answer/35738 echo "&lt;?xml version=\"1.0\" encoding=\"UTF-8\"?&gt; &lt;urlset xsi:schemaLocation=\"http://www.sitemaps.org/schemas/sitemap/0.9  http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns=\"http://www.sitemaps.org/schemas/sitemap/0.9\"&gt;" &gt; $path  echo '     ' &gt;&gt; $path;    for ((i=0;i&lt;${#array[*]};i++)); do echo "&lt;url&gt;     &lt;loc&gt;${array[$i]:0}&lt;/loc&gt;     &lt;lastmod&gt;$date&lt;/lastmod&gt;     &lt;changefreq&gt;$freq&lt;/changefreq&gt;     &lt;priority&gt;$prio&lt;/priority&gt; &lt;/url&gt;" &gt;&gt; $path    done echo "" &gt;&gt; $path echo "&lt;/urlset&gt;" &gt;&gt; $path  # notify Google # URL encode urls as per https://support.google.com/webmasters/answer/183669 if [[ "$debug" = [nN] ]]; then     wget  -q --delete-after http://www.google.com/webmasters/tools/ping?sitemap=http%3A%2F%2F${url}%2Fsitemap.xml      rm -rf ${url} else     echo "wget  -q --delete-after http://www.google.com/webmasters/tools/ping?sitemap=http%3A%2F%2F${url}%2Fsitemap.xml"      echo "rm -rf ${url}" fi echo "------------------------------------------------------"  exit 0 In a family with two children, what are the chances, if one of the children is a girl, that both children are girls?  I just dipped into a book, The Drunkard's Walk - How Randomness Rules Our Lives, by Leonard Mlodinow, Vintage Books, 2008. On p.107 Mlodinow says the chances are 1 in 3.   It seems obvious to me that the chances are 1 in 2. Am I correct? Is this not exactly analogous to having a bowl with an infinite number of marbles, half black and half red? Without looking I draw out a black marble. The probability of the second marble I draw being black is 1/2. underline omitting the descenders I'm very well aware that it is considered best practice not to use underlining other than on typewriters and in handwriting. But sometimes it is needed nonetheless.  In my opinion the typographically least offending way to underline in print is to leave out the descenders. This is also how I learned to do it in handwriting. Very few fonts offer a pre-made underlined variant, but some text-processors (e.g. OS X text-engine) do -- depending on the font used -- an acceptable job at emulating this effect:    How would I tweak any of the existing ways/packages for underlining to do the same?  As a bonus, I'd like to be able to tweak the behaviour (extent of the omitted part, apply to which letters) per font and text style, preferably working with XeLaTeX.

Linux, find all files matching pattern and delete Looking to find all files (recursively) which have an underscore in their file name and then delete them via command line. Is there a way of conditionally triggering a compile-time error in verilog? I have a parameterised module in verilog, where the parameters are a clock rate and refresh rate, which is used to calculate how many cycles of inactivity are inserted between instances of a repeating operation.  However, it is very easy to set parameters that cannot be attained (because the operation takes a non-trivial length of time, so the repeat would have to occur before it had completed), and at the moment the design does not give any feedback on this.  I was wondering if there was some way I could trigger an error during synthesis (or compilation prior to simulation) if the conditions cannot be met (i.e. if one localparam is less than another)?  Some equivalent of the popular C/C++ compile-time-assert hack, perhaps. When trying to SSH into a particular Mac machine it gives me the following error :  ssh_exchange_identification: Connection closed by remote host   I have done some google searches on the issue but I haven't seem to find a definite answer. I did notice that on the machine that I am trying to SSH into, it does not have the ~/.ssh file even on there so I went ahead and created it and gave it correct permissions but that didn't help.

OpenCV argc and argv confusion Geometric mean never exceeds arithmetic mean This was a mathematical induction question proposed in a textbook, and I've exhausted multiple approaches (proving RHS - LHS > 0, splitting the fraction, fractional exponents, etc.)     The geometric mean of $n$ positive numbers $a_1, a_2,\ldots,a_n$ is $\sqrt[n]{a_1a_2 \ldots a_n}$ and their arithmetic mean is $\frac{a_1+a_2+\ldots+a_n}{n}$. If $a_1, a_2,\ldots,a_n$ are $n$ positive real numbers, prove by induction that their geometric mean is always smaller than or equal to their arithmetic mean, i.e. $\sqrt[n]{a_1a_2\ldots a_n} \leq \frac{a_1+a_2+\ldots+a_n}{n}$ Get DOS path instead of Windows path Integral ${\frac{1}{\pi^2}} \int_{0}^{\infty}\frac{{(\ln{x}})^2}{\sqrt{x}{(1-x)^2}} \mathrm d x$ How to check if specific column exists in an Access database table When to use “that” and when to use “which”, especially in relative clauses When is it appropriate to use that as opposed to which with relative clauses? C#: code error while changing the active directory user's password Software center not loading software lists Does the full quarantine period have to be observed for short trips of less than 14 days to England? I am planning to go to England for 2 days in preparation of moving (I already have a place rented and would be staying there) a few weeks later. I am coming from a country where I would need to do a 14 day quarantine as soon as I enter England. Does this mean that I have to stay in England for 14 days or can I leave the country before the end of the 14 day quarantine without facing a penatly? I have found no information about what the rules are for planned stays of less than 14 days on the , while  seems to say that short trips are OK. Official sources would be appreciated.
