Doesn't Sherlock's comment to Watson during their good bye scene suggest that there is/was a third Holmes sibling and that the sibling is a woman?
Is there a third Holmes sibling?
Handle either a list or single integer as an argument Which lenses should be included in a travel photography kit? On a crop sensor camera, e.g. Canon EOS 7D, what would be the best kit to travel with around Europe for a few weeks? My shooting style will focus on landscape, architecture, and general travel shots (of note would be my lack of interest for portraits).     Limit to around 1-3 lenses, and I prefer light ones.   Crop sensor camera chosen to save on weight over a full frame option. Question is open to all brands for general guidance, but I will be using a Canon body.   Cost is not a factor, I will rent the lenses I do not already own.   Quality is of paramount importance. I will not have a tripod.   I understand some may consider this subjective, but I do believe that for a crop sensor body, with weight as a consideration, and a limit to the amount of lenses, a true best kit can be determined. How to see time stamps in bash history? Is there any way I can see at what time the commands were executed from the bash history? We can see the order but is there any way I can get the time also?  Bottom-Line: Execution time in the Bash history How to get my actual data from ContentNote API in Salesforce using SOQL? Why are our planets in the solar system all on the same disc/plane/layer? I always see pictures of the solar system where our sun is in the middle and the planets surround the sun. All these planets move on orbits on the same layer. Why? Is it possible to embed a scrollable frame inside a PDF? (This is an end-of-year crazy question)   Is it possible to embed a (scrollable) frame or a PDF inside a PDF? If so, how to do it in (pdf)LaTeX?  This is something pretty common in HTML (see for example ). Here it is a webpage with PDF frames   Here it is a fake screenshot so you get the idea.  Portable and non-portable (e.g. only-Acrobat) answers are welcomed.     Example of a down arrow below a frame. The up arrow can be on top of the frame and the triangles point up. fontenc changes sans serif bold font in KOMA-script Consider the following MWE:  \documentclass{article} %\usepackage[T1]{fontenc}  \begin{document}  \textbf{\textsf{Some text}}  \end{document}   The output of the above code is     and doesn't change if I uncomment the line  %\usepackage[T1]{fontenc}   Consider now the following MWE with scrartcl class instead of article:  \documentclass{scrartcl} %\usepackage[T1]{fontenc}  \begin{document}  \section{A section} \textsf{Some text} \end{document}      Uncommenting the line  %\usepackage[T1]{fontenc}   you get    As you can see, the sans serif font of the title is less  bold than without fontenc, while the normal text is not changed.  Does fontenc, combined with a KOMA-script class, load a different sans serif font, but only for bold face? Xpath expression with multiple predicates What is virtual memory? I was double checking my notes for 'Virtual Memory' and the definition in my text book is:     Process of allocating a section of secondary storage to act as part of the main memory   Where as  says:     Virtual memory is a computer system technique which gives an application program the impression that it has contiguous working memory (an address space)   and (Wikipedia also says)     Note that "virtual memory" is more than just "using disk space to extend physical memory size"   Can anyone offer any clarification as to which is correct? Proving that two matrices are congruent, in order to establish a rank and signature result. I'm assuming that the answer to the question in the title is a resounding yes. Since Baryonic matter and dark matter interact via gravitational forces.  If this is the case how is information not lost if, as is presumed, dark matter does not interact via the electromagnetic force? how to change the distance between tick mark and tick label Define path for packages in the LaTeX file (analog of \input@path or \graphicspath for \usepackage) Proving the AM-GM inequality for 2 numbers $\sqrt{xy}\le\frac{x+y}2$ I am having trouble with this problem from my latest homework.  Prove the arithmetic-geometric mean inequality. That is, for two positive real numbers $x,y$, we have $$ \sqrt{xy}≤ \frac{x+y}{2} .$$ Furthermore, equality occurs if and only if $x = y$.  Any and all help would be appreciated. Editing and manipulating tables with ArcPy? I’m new to ArcMap and was wondering if anybody could help me out. I have a shapefile with counties and wells in that county. In the table I’m trying edit it so that for each county calculate the total numbers of wells that fall into that county, and update the county table with the total count. I also want to calculate how many wells there are per area unit, and update the table with that value as well.  import arcpy featureClass = "C:/Lesson5_Data/Colorado_cities.shp" fieldList = "*"  with arcpy.da.SearchCursor(featureClass, fieldList) as cursor: for row in cursor: print row[4  population = 10000  whereClause = '"POP2007" &gt;= ' + str(population In terms of UX what do you guys think is the best approach when integrating a trial period for subscriptions?  My application offers a 15 day trial, at the minute the user can sign up without providing any payment information (Paypal Subscription). The account is then set to trial status and after 15 days the user will be redirected to an upgrade page.  Do you think this is the best approach? I am unsure whether or not to let Paypal manage the trial, this however means that the user will need to go through the Paypal payment system during signup. I think this may put some people off signing up.  On the other hand this approach may increase the number of conversions to a full account. I want to have a  video background that will loop on some frames of my presentation. Can anyone help me to do that? I am notified about old comments instead of new ones I have three notifications pending but when I open the tab they were a month ago. When I refresh the page I see the correct three notifications. Pictures:  Here you see notifications from March but it is April:    Here I refreshed the page and recognized that there are indeed three unread notifications.    This behavior occurred already three times before, always with the spinlock question as first comment. Today I finally realized that there were indeed notifications pending.  Is this a bug to report? If this is not the right side to ask about this - where should I go to?  Edit 1  Browser: Firefox 28.0 (current version) Windows 7 on a Laptop  It only appears on the favourites side. When I open  I see the current comments.  Edit 2  On favourites I see the old issue    On meta and stackoverflow I see the new comment   Edit3  Still an issue on April 11th and April 16th. The question is more like: Can somebody remove this or show me a way to remove it or let it remove?  Edit4  April 20th at 14:00GMT the favourite tags turned into an error page: I can't seem to find an answer to this simple question, which I need for some compliance documentation.    On a default install of CentOS 6.5 (OpenSSH 5.3p1-94.el6), after how long of being idle will a user's SSH session be terminated?  I believe the following can be set to increase the idle timeout, but they are commented out by default.  $ grep -i alive /etc/ssh/sshd_config #TCPKeepAlive yes #ClientAliveInterval 0 #ClientAliveCountMax 3   Also, is there a command to dump a list of the current sshd settings?  I don't see anything in man sshd. Convince grep to output all lines, not just those with matches Say I have the following file:  $ cat test  test line 1 test line 2 line without the search word another line without it test line 3 with two test words test line 4   By default, grep returns each line that contains the search term:  $ grep test test  test line 1 test line 2 test line 3 with two test words test line 4   Passing the --color parameter to grep will make it highlight the portion of the line that matches the search expression, but it still only returns lines that contain the expression. Is there a way to get grep to output every line in the source file, but highlight the matches?  My current terrible hack to accomplish this (at least on files that don't have 10000+ consecutive lines with no matches) is:  $ grep -B 9999 -A 9999 test test     If grep can't accomplish this, is there another command-line tool that offers the same functionality? I've fiddled with , but it doesn't seem to have an option for it either.
