How to tell Google that I have changed my website URLs? I have read , but it was asked in the context of servers not desktops or notebooks.  If a good amount of RAM is installed on a notebook, say 8 GB, do we still need a swap space? Is a Schengen visa/transit visa required for a transit flight through two Schengen airports? I am travelling form Delhi (DEL) to San Francisco (SFO), I have to make a connection flight in Vienna that would take me to Frankfurt (FRA). My flight to SFO is from FRA, I have one ticket for entire journey and the flights are operated by Lufthansa or its subsidiaries.  Do I need a transit visa? My flight arrives at Vienna international airport and leaves from the same, and for second leg it arrives at Frankfurt international airport.  I asked this question as an addendum to my  but was advised to make a new post.  I hold Indian passport and valid US visa. Should edits with only minor code improvements be accepted. As an example, I'm reviewing an edit that changes all double quotes to single quotes and renames a variable in some javascript. With the exception of the variable rename (which is not entirely necessary), the edit is frivolous. Should I accept on the merits of a debatable variable name change? Error: 'else' without 'if' What causes the dimensions of a star increase when its hydrogen fuel is exhausted? In MS SQL how do I find out what tables have not been queried or updated in a long time? Remove all content using pure JS How is listed DPS calculated when dual-wielding weapons? I was trying out the dual-wielding in Diablo 3, when I noticed really strange. When I equipped my off-hand, which has 0.5 less damage than my main-hand. My overall damage actually went down. So my question is, how does the dual-wielding mechanic work for calculating damage? It seems rather odd that my overall damage should be more with one weapon than with two. My computer does not store the history of the entries entered in RUN (WIN+R).   Thus, how to enable Windows to store the history? Anonymous questions and Avatars How to install KDE along Unity? I have just installed the latest Ubuntu 14.04 and I would like to install KDE along side my Gnome/Unity that I have now. How can I do this?  Thanks! What TV movie had lost space cadets who piloted yellow tripod robots, and a squid bad guy? Is There Any Way to get the template Name By full URL for example  If the full url is  www.example.com/hello-world   I need a function that return the template name (page.php)  I know that WordPress matches every url with regular expression to determine the query and decide which template to include.  That's exactly what I need, a built in or (custom made) function that takes the URL and returns back the corresponding template Quantify Difference/Distance between Lognormal distributions I am trying to determine a metric that quantifies the distance between two continuous lognormal distributions. The data is actually a mixture of two lognormal distributions (I am not sure if this can be called bimodal). The individual distributions have different means but the same standard deviations. I have 20 data sets that can be divided into 4 groups, with each group having a constant standard deviation, but the 5 data sets in each group are made up of two distributions with different means. Some examples:      I am in search of a metric that accounts for the contrast (difference in means) and the standard deviation. I have tried out some parameters like coefficient of variation (of the mixture), Ashman's D etc. I have also tried percentage of overlap. However the problem always is that, at the end when plotted against the results I end up with 4 trend-lines again, corresponding to the 4 different standard deviations. Is there some other way I can quantify this?  Just to make myself clear, I want to quantify the difference between two distributions in a single case (between the red and green PDFs in the above image). Decode Base64 data in Java When I wake the laptop from the sleep I need to get the VPN state as I left it (turned on). Can't find the setting of autoconnect in VPN settings... Need some easy way to ask the system to autoconnect the VPN when the internet is available.  Edit based on comments:  Ubuntu 18.04 has no option to Always connect to VPN when using using this connection. When should I use a unique constraint instead of a unique index? When I want a column to have distinct values, I can either use a constraint  create table t1( id int primary key, code varchar(10) unique NULL ); go   or I can use a unique index  create table t2( id int primary key, code varchar(10) NULL ); go  create unique index I_t2 on t2(code);   Columns with unique constraints seem to be good candidates for unique indexes.  Are there any known reasons to use unique constraints and not to use unique indexes instead? How can I customize a system locale? Geometric solution to find a Set of totally ordered Subsets of $ \mathbb{N} $ is uncountable My question is, does there exist a set of subsets of the naturals, $S$, such that $S$ is uncountable, where for any two subsets $A,B \in S$ we have either $A \subset B $ or $B \subset A $?  Initially my thoughts were that we could construct a chain $A_{1} \subset A_{2} \subset \cdots $ and find a bijection by picking out one element which is 'new' to each set by axiom of choice and so we have bijected to a subset of naturals, however I'm not convinced this fully works.  Furthermore, I was thinking there may be a nice elegant solution by looking for such a set in either $ \mathbb{Q}^2 $ or $ \mathbb{Z}^2 $ for example, but any attempt seems to fail due to the 'ordering' part of the question.
