When I use the search engine, when and why does it auto-convert some keywords to tags?   For example, when I input "jav" in the search engine, it gives me 283 results including relevant questions and answers.   When I input "java" in the search engine, it links to the tagged questions page. How does that work?
Asume the following search queries: osx, cocoa, iphone, xcode, applescript, mac, carbon    Searching for osx, cocoa, iphone or xcode like:   http://stackoverflow.com/search?q=osx   Results into searching by tag:   http://stackoverflow.com/questions/tagged/osx   While searching for applescript, mac and carbon like:   http://stackoverflow.com/search?q=applescript   Results into searching by string.  Yes, I know how to search by tags using brackets: [applescript] But why are the queries above interpreted differently? All queries are valid Stack Overflow tags! Why not convert all queries into search by string or search by tag? What is the logic behind? Tag popularity? It seems rather inconsistent to me.
Sum of closed spaces is not closed How to read ND filter description? When I search on Amazon for eg. neutral density 67mm, I get long list of different filters. Some of them are marked like: ND2, ND4, ND8 etc. I'm guessing this means 2-, 4- or 8-stops filter, am I right?  But what about filters, that say 0.6 or 0.9? What does this mean?   Is there any other thing (apart of stops and diameter) that I should also pay attention to when choosing a filter? Permanent xmodmap in Ubuntu 13.04 I cannot make xmodmap run on login in Ubuntu 13.04. I have searched around, including in askubuntu and all answers I found do not work.  I have a file named .Xmodmap in my home folder which contains the desired mappings. If I run it manually it works fine, so there is no error there. In order to make it run on startup, I have tried:     Using various .xinitrc containing one of the following commands:      xmodmap .Xmodmap xmodmap ~/.Xmodmap   /usr/bin/xmodmap /home/NAME/.Xmodmap if [ -s ~/.Xmodmap ]; then xmodmap ~/.Xmodmap fi  Using .Xresources instead of .xinitrc with the same variations. Setting it as a startup application.   None of the above works in Ubuntu 13.04 (64-bit). I also saw a few ideas about globally changing the keyboard mappings, but most of them were not applicable in Ubuntu 13.04 (i.e. the corresponding files did not exist where specified) and I prefer not to touch the global settings anyway. Did Tyrion even have the authority to do this? In Game of Thrones S08E04 (The Last of the Starks) when Tyrion and Jaime are confronted by Bronn, Tyrion attempts to evade poetic justice by offering Bronn Highgarden. Was it even within Tyrion's power to give away Highgarden?    Follow up question: Why would Bronn even risk waiting around to see how things play out? Based on his demeanor during that conversation, he seemed pretty pissed that all he has to show for serving the Lannisters is a lousy title. So, why wouldn't he just take bird in hand and collect the reward from Cersei instead of risking Tyrion dying before all of this is over? I mean, Tyrion even mentioned to him that all of this means nothing until they [the North] take over King's Landing, but it didn't really seem to faze Bronn. What is this yellow and white mass inside my red cabbage? Need of the cold body in heat engine What is $\lim_{n\to \infty}\sum_{k=1}^n \left(\frac{k}{n}\right)^n$? I'm asked to find $\displaystyle\lim_{n\to \infty}\sum_{k=1}^n \left(\frac{k}{n}\right)^n$.  It seems that the sum converges.  I managed to prove that $\forall n,1&lt;\sum_{k=1}^n \left(\frac{k}{n}\right)^n&lt;e$  But I don't know how to prove convergence, nor find the value of the limit.

Lock keys panel indicator for MATE Desktop I have no indicator LEDs on my keyboard to show whether Caps-Lock is on (I don't have Num-Lock and Scroll-Lock keys so the best option would be to have an indicator only for Caps Lock, but three indicators would be better than none)  I would really like to see the lock-keys status in the indicator panel so I can tell at a glance whether I'm typing my passwords correctly    I'm using Ubuntu MATE 16.04.

R stem and leaf values How to make a stem and leaf plot with the following data in "R":  1717 1719 1645 3739 3024 3664 3830 2991 2430 2730 3469 5086 2119 3021 3292 2844 3426 2067 3215 2767 3124 2573 2840 2449 2584 1505 1390 1645 2497 3466 3228 3192  The only way to get a reasonable amount of stems is to make the stem the first digit in each number and the leaves will all be 3 digit numbers. I am not able to split the data in this way, R represents the stem with 1 digit but round my numbers  so 2584 is shown as 2| 5 (3 decimals to the right) which would be 2500. How do I adjust my stem and leaf numbers? How to activate hyphenation in \ttfamily without explictly setting a font? I am suprised that in the code below no hyphenation is done.

I am trying to prove this binomial identity $\sum_{r=0}^n {r {n \choose r}} = n2^{n-1}$ but am not able to think something except induction,which is of-course not necessary (I think) here, so I am inquisitive to prove this in a more general way.  The left side of an identity occurs while solving another problem (concerning binomial theorem) so I am more interested in deriving the right side from the left side, else I have to remember it now onward.  EDIT: I am more interested in an algebraic proof rather than combinatorial argument or something involving calculus (however I liked  and  solution), hence I am removing the combinatorics tag. How to open recovered files in word? My computer restarted while I was asleep because of system updates (need to turn that off), and when I opened up Word the first time after it restarted, it gave me a pane on the left hand side that showed me all the documents I had opened.  I chose one of the documents but I want to open them all, how can I bring that pane back?    Update:  I forgot to mention I'm on Word 2007.  I've found that if you go to      C:\Users*YOURUSER*\AppData\Roaming\Microsoft\Word   you can see the autorecovery files.  Mine are still in there, but I don't want to touch them, I'd rather bring back that pane and do it right just in case they disappear as soon as I double click haha... I cant change to faces or edges view! Do you need line of sight to cast spells on someone?
