On my system I am getting errors(?) like this:  bash: warning: setlocale: LC_CTYPE: cannot change locale (en_DE.UTF-8)   or    weemonger@awesomeLinuxSystem:~$ dpkg-reconfigure locales perl: warning: Setting locale failed. perl: warning: Please check that your locale settings:         LANGUAGE = "en:de:en",         LC_ALL = (unset),         LC_PAPER = "en_DE.UTF-8",         LC_ADDRESS = "en_DE.UTF-8",         LC_MONETARY = "en_DE.UTF-8",         LC_NUMERIC = "en_DE.UTF-8",         LC_TELEPHONE = "en_DE.UTF-8",         LC_IDENTIFICATION = "en_DE.UTF-8",         LC_MEASUREMENT = "en_DE.UTF-8",         LC_TIME = "en_DE.UTF-8",         LC_NAME = "en_DE.UTF-8",         LANG = "en_DE.UTF-8"     are supported and installed on your system. perl: warning: Falling back to the standard locale ("C").   How do I fix my system an get rid of the locale warnings/errors?  I have to say, that I living in Germany and use the english (en) language for my system, but also I have configured my system to use the german (DE) formats/norms for Numbers, Money, Measurements, Page size, etc. I did this using the KDE Control Module Country/Region &amp; Language.    I think I got rid of the warnings by myself, so I will post an answer myself, but wait some time before I accept it, as I didn't fully grok/understand it.
How do I set up a global locale for the computer?  I have recently installed Kubuntu 14.04LTS in english but since I am in Spain, I chose Spain as a country and then changed locale options so that I get all country specific configuration such as digit grouping, decimal separator, date format, etc. I also added the spanish language.  Now all applications complain that locale is wrong. check-language-support tells me I'm using en_ES.UTF-8 as system's locale, and that locale is indeed wrong, there is no locale for english language in Spain.  I tried using Kubuntu's country/region &amp; language settings but it doesn't fix it. I tried using export LANG=en_GB.UTF-8 and export LC_ALL=en_GB.UTF-8 and then sudo dpkg-reconfigure locales and that caused check-language-support to say that I now have a correct configuration but if it is, it's only in that konsole session. This problem also prevents konsole from showing unicode characters and I cannot use dead keys or enter any 'international character' such as ñ or ç (those work on other applications such as Firefox, that I'm using to post this question).  So the question is: How do I set up a global locale for the computer?  This is not a bug report, I will probably reinstall my computer eventually if I can't fix it. But I really want to know how I can perform this REALLY basic task.  Thank you.  $ check-language-support perl: warning: Setting locale failed. perl: warning: Please check that your locale settings:         LANGUAGE = "en:es:en",         LC_ALL = (unset),         LC_PAPER = "en_ES.UTF-8",         LC_ADDRESS = "en_ES.UTF-8",         LC_MONETARY = "en_ES.UTF-8",         LC_NUMERIC = "en_ES.UTF-8",         LC_TELEPHONE = "en_ES.UTF-8",         LC_IDENTIFICATION = "en_ES.UTF-8",         LC_MEASUREMENT = "en_ES.UTF-8",         LC_TIME = "en_ES.UTF-8",         LC_NAME = "en_ES.UTF-8",         LANG = "en_ES.UTF-8"     are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_MESSAGES to default locale: No such file or directory locale: Cannot set LC_COLLATE to default locale: No such file or directory hunspell-en-ca libreoffice-help-en-gb libreoffice-l10n-en-gb libreoffice-l10n-en-za mythes-en-au wspanish  $ cat /etc/default/locale LANG="en_US.UTF-8" LC_NUMERIC="es_ES.UTF-8" LC_TIME="es_ES.UTF-8" LC_MONETARY="es_ES.UTF-8" LC_PAPER="es_ES.UTF-8" LC_NAME="es_ES.UTF-8" LC_ADDRESS="es_ES.UTF-8" LC_TELEPHONE="es_ES.UTF-8" LC_MEASUREMENT="es_ES.UTF-8" LC_IDENTIFICATION="es_ES.UTF-8"   $ locale locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_MESSAGES to default locale: No such file or directory locale: Cannot set LC_ALL to default locale: No such file or directory LANG=en_ES.UTF-8 LANGUAGE=en:es:en LC_CTYPE="en_ES.UTF-8" LC_NUMERIC=en_ES.UTF-8 LC_TIME=en_ES.UTF-8 LC_COLLATE="en_ES.UTF-8" LC_MONETARY=en_ES.UTF-8 LC_MESSAGES="en_ES.UTF-8" LC_PAPER=en_ES.UTF-8 LC_NAME=en_ES.UTF-8 LC_ADDRESS=en_ES.UTF-8 LC_TELEPHONE=en_ES.UTF-8 LC_MEASUREMENT=en_ES.UTF-8 LC_IDENTIFICATION=en_ES.UTF-8 LC_ALL= $ update-locale perl: warning: Setting locale failed. perl: warning: Please check that your locale settings:         LANGUAGE = "en:es:en",         LC_ALL = (unset),         LC_PAPER = "en_ES.UTF-8",         LC_ADDRESS = "en_ES.UTF-8",         LC_MONETARY = "en_ES.UTF-8",         LC_NUMERIC = "en_ES.UTF-8",         LC_TELEPHONE = "en_ES.UTF-8",         LC_IDENTIFICATION = "en_ES.UTF-8",         LC_MEASUREMENT = "en_ES.UTF-8",         LC_TIME = "en_ES.UTF-8",         LC_NAME = "en_ES.UTF-8",         LANG = "en_ES.UTF-8"     are supported and installed on your system. perl: warning: Falling back to the standard locale ("C").
Adding table of certain attributes to map layout? I am using ArcMap 10.2 and I'm looking for a way to add  a table containing certain fields from select elements from a featureclass to my map. Ive tried the add table option from the attribute table, but it doesn't quite give what I want (the table must be editable to look a certain way).   Are there any options out there for 10.2 like arcpy.mapping.tableview or will upgrading to 10.3 so I can get access to the "graphic table element" function be best? Asserting that Atheism and Theism are both faith based positions I am recently testing an assertion that I have concluded namely that atheism is a faith based position just like theism is a faith based position.  The reason I arrived at this conclusion is that theists have no proof that God actually exists. It's purely a matter of faith. Yes, there maybe strong implicit proof that God exists in their opinion (scriptures, history, etc) but there is no concrete proof of God's existence. In my view, atheists also suffer from the same problem of providing a proof of their position. Specifically that they cannot prove that God is non-existent.  The typical rebuttal I get is that the burden of proof is on the theists. But I view this as a cop out and they hide behind the wall of burden of proof which is just a bias in the debate.  Given the above, I claim that both atheism and theism are positions based on faith. Would it be incorrect to claim that? I just broke the screen of my (unrooted) Galaxy S.  How do I get back my SMS and contacts?   PS: I tried Kies but it won't detect my phone for some reason. (Kies works fine with another Galaxy I possess but not this one) Isomorphism of a product $C_n \times C_m$ of cyclic groups with the cyclic group $C_{mn}$ Given that $C_n$ is a cyclic group of order $n$, what conditions must integers $n$ and $m$ satisfy such that the group $C_n \times C_m$ is isomorphic to C$_{mn}$?   So I attempted to investigate a few lower-order cyclic groups to find a pattern. In particular, I looked at $C_2 \times C_3$ and compared it to $C_6$. Here are a couple of diagrams:  $C_2 \times C_3$ -   $C_6$ -   They Cayley tables look pretty different (identity elements are all over the place for $C_2 \times C_3$) so I concluded that they are not isomorphic.  I did the same for $C_2 \times C_4$ and $C_8$:  $C_2 \times C_4$ -   $C_8$ -   Again, I arrived at the conclusion that the 2 groups are not isomorphic due to their Cayley table structure.  It seems I'm stuck now. Are my conclusions wrong for the examples I examined? If so, how do I find the conditions for the general case of comparing $C_m \times C_n$ with $C_{mn}$? Checking incoming call in iphone Axiom of Choice: Where does my argument for proving the axiom of choice fail? Help me understand why this is an axiom, and not a theorem. In terms of purely set theory, the axiom of choice says that for any set $A$, its power set (with empty set removed) has a choice function, i.e. there exists a function $f\colon \mathcal{P}^*(A)\rightarrow A$ such that for any subset $S$ of $A$, $f(S)\in S.$ Is this correct?  My question then is about proving this fact, so that we do not need to put it as an axiom. Now as per the research done on this single object- Axiom of Choice, I believe here that there should be some falsity in my argument. I do not find the mistake.  For any $S\in \mathcal{P}^*(A)$, since $S\neq \emptyset$, $\exists s\in S$. Define $f(S)=s$. Then $f$ is a choice function.  This was showing me that the axiom of choice is proved, but then why it had been put as an axiom? For example, in  book, the author asserts that      It is a metatheorem of mathematical logic that it is impossible to specify the function that assigns to each non-empty subset of $\mathbb{R}$, an element of itself.     There are several notes and books on axiom of choice, but here I am trying to understand through doing some argument for some problem, where problem actually arises. I use my computer for scientific programming. It has a healthy 8GB of RAM and 12GB of swap space. Often, as my problems have gotten larger, I exceed all of the available RAM. Rather than crashing (which would be preferred), it seems Ubuntu starts loading everything into swap, including Unity and any open terminals. If I don't catch a run-away program in time, there is nothing I can do but wait - it takes 4-5 minutes to switch to a command prompt eg. Ctrl-Alt-F2 where I can kill the offending process.  Since my own stupidity is out of scope of this forum, how can I prevent Ubuntu from crashing via thrashing when I use up all of the available memory from a single offending program?

There is an UI issue for the ranking div when a user crossed 200 reputation When a user just crossed 200, or 200+ reputation, the ranked div (i.e., top 10% overall) is trying to display. But rank calculation can be done on end of the UTC day. So instead of the ranking div, there is a blue colored hyphen is visible to users, it may be the initial loader for the ranking div.  I saw this UI issue previously too for the same scenario. Can this be fixed? I'm a US citizen and I've already gotten my Tier 4 visa to study in the UK in my passport, however, it looks like the start date on the visa and the letter to present to the Immigration Officer has allowed me entry an extra week on top of the usual month. My school starts on September 24th, but my visa states permission to enter on August 17th. I've read that you are only allowed a month before the beginning of school, but my visa is saying differently!  Should I assume its wrong and enter on the 24th or is it okay for me to enter on the 17th?   Thanks. I'm using LyX on Linux Mint 14 ...  Using BibTeX with the apalike style and some modifications in the preamble, I've managed to get the bibliography as it should be except for one thing. When I cite a work with multiple authors it gets printed with the separator "and" which isn't correct for my language (Danish). Curiously it's displayed correctly in the user interface of Lyx - for example "(Wittgenstein og Waismann 2003 - which led me to believe everything was ok but in the pdf the separator "and" is used both in the reference and in the bibliography.  Is there any way to fix this using BibTeX, or can it only be done with biber 1.5, as suggested in the last comment here:   I really hope their is because getting biber to work using the following guide has thus far proven to be impossible:   Help much appreciated ... I really hope I won't have to relapse into setting my master thesis up in LibreOffice. How can I clear the water out of this area? I've sectioned of this area in the sea near my base, and I need to get rid of all the water from it.  From what I've tried the only way I can see to clear it is fully cover one layer, delete the blocks, then go down to the next layer. Is that the only way I can clear the area or is there a better approach?

After looking around a bit, it seems to be on all deleted posts now (only deleted posts, normal posts still say just add comment).  I'm sure it wasn't there before (I think it just said add comment (unclickable) or possible nothing).  It is also on , presumably the root cause is the same.  And yes, I do have more than 50 reputation (in case anyone was wondering).  Just to clarify, requires 50 reputation obviously shouldn't be there for users with 50 or more reputation. Choices:   Display nothing Unclickable add comment - probably not ideal Unclickable add comment (disabled for deleted posts) or something along those lines   FYI - You may be somewhat confused right about now if you can't  yet. How to see the error messages when I get the white screen of death? How can I see the error messages when the site I am working on gets a white screen? What lens characteristics are important in star photography? I posted this at  and got redirected here. This does indeed look like a better place to ask.  I would like to decorate my headlines (section, subsection, etc.) by adding a background color. I would like this box filled with a single solid color to span across the entire typearea.  This picture is a screenshot of an OpenOffice document where the headline has the formating, layout and color I want.    Requirements on a solution   The resulting style is supposed to be used by others, meaning an equivalent latex output to the picture above shall be created by this code:  Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text   \subsubsection{This is a headline}  Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text Some Text  If the section is supposed to be unnumbered one should be using \subsubsection*. LaTeX still needs to be in charge of the whitespace between paragraphs and the blue box.   What I have tried so far  As far as I can google the headline together with the section numbering are a simple paragraph. Latex adds some skips before and after and squeezes in a few commands that modify the font(s).  My ideas revolve around locking this paragraph in a \colorbox. The colorbox macro works like this: \colorbox{color}{the content around which to draw a box filled with the specified color}. My problem is I can't get a grasp on this paragraph.  The easy 80%  My work is based on koma-script and by redefining \othersectionlevelsformat and \(sub)*section. I can draw two boxes, one surrounding the section numbering and another surrounding the section title. However this has 3 open issues:   the upper edges of the boxes are unaligned and the box with the title is slightly larger than the line with the numbering The box around the title does not strech to the right end of the typearea the box around the numbering doesn't grow if the title spans multiple lines (no surprise here)   The hard 20%  I tried to make latex put the section numbering into a \savebox I could access later and put as part of the title. That would eliminate the need for two boxes and solve all three of my problems at once, but that doesn't work. I only get to modify the title before the actual numbering is done. So while I can put the numbering into a savebox, I can't do anything with it until it's too late.  I tried putting the \section ... statement into a colorbox, but it doesn't like that and the document fails to compile with ! LaTeX Error: Something's wrong--perhaps a missing \item. The same holds for saveboxes. I guess colorbox uses those.  I tried putting the \section ... statement in a minipage and put a box around that. This has two issues. 1st: latex doesn't put any empty space above a section. 2nd: not only the section numbering and title have the background but also the empty space between section title and first paragraph.  So how can one hack latex to do a section title formating as shown in the screenshot above?
