Hi I found an old laptop that I would love to find out what is still on it. I hadn't updated an ubuntu that was installed in 2009. Any Idea on how to change a forgotten username and password from the login screen?
I'm working on a Ubuntu system, and my client has completely forgotten his administrative password. He doesn't even remember entering one; however it is there.  I've tried the suggestions on the website, and I have been unsuccessful in deleting the password so that I can download applets required for running some files. Is there a solution?
How do they compute the Gold and Elixir that can be looted? How do they compute the Gold and Elixir that can be looted from a base? Is it 100% of the remaining? or the total (including the uncollected from mine)? How to set date format when manually inserting date on excel, without changing regional settings? In my locale, date is inserted as dd/mm/yyyy or variations of that (including dd-mm-yy). I made an Excel form (in normal Excel file), already formatted to show date as dd/mm/yyyy, but when I typed "05/04/2015" it will be shown as "04/05/2015". I know this can be solved by changing the regional setting to my local setting, but I need to distribute this form to a lot of people with no knowledge of changing regional setting, and assuming no one can teach how to, hence my question :  Is there any way to input "05/04/2015" and be recognized as "5 April 2015", without having to change regional settings ?  Additional note: When I mean "4 May 15" (typed in 4/5/15), Excel will recognize this as "5 April 15" because Excel takes input as "mm/dd/yy" format. I need to change the default behavior of Excel to take as "dd/mm/yyyy" as this is the way the users will input.  If possible, the setting should also included/embedded on the file to allow end-users use the form without even changing setting.  I'm not familiar with macros and VBA, but willing to try those :)  EDIT : this is related to my question :   but I don't need to change the whole formula bar, as long as Excel recognize that I'm typing in dd/mm/yy format. It seems as if a shift occurred and the descriptive "Oriental" was replaced by "Asian" as the accepted term in polite society — what caused this shift? Why the value of $PATH is different for root and normal user? for normal user I get :     /usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/monty/google_appengine   which is actually the content of /etc/environment  For root I get:     /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin   what's the reason behind this and which file contains this line? Is denying "Paradoxical Partitioning" equivalent to accepting the Axiom of Choice? In  (to ) it has been noted:     One more point to make about the paradoxical decomposition to more parts than elements [...]   currently we do not know of any model of +$\lnot$ where such decomposition does not exist.    Namely, as far as we know, in all models where choice fails there is some set which can be partitioned into more parts than elements.   (Just for clarification: From the context of the above references the comparison "more parts than" is obviously meant in terms of the  of the suitable  being strictly larger than the cardinality of the suitable initial set itself.)  Now, I find the negation or denial of such "paradoxial partitioning" interesting; i.e. the statement (proposition, "$\lnot$PP"):  "Each partition of each given set has cardinality less than, or at most equal to, the cardinality of the given set."  And I like to further explore how this suggested "proposition $\lnot$PP" (being considered along with ZF, of course) relates to "the standard set theory including Axiom of Choice", . Therefore  My questions:      Are there any models of ZFC known (or could there be any such models, in principle) in which there is some set which can be partitioned into more parts than elements ?  And:  Are there any models of ZF known (or could there be any such models, in principle) in which there is no set which can be partitioned into more parts than elements, and which is not also a model of ZFC ?  (And just for reference: Is there a conventional or concise way of expressing the suggested "proposition $\lnot$PP" in terms of standard notation, such as used in the sources linked above? Has it perhaps been discussed already, by some other name? ...) How can I "grep" patterns across multiple lines? It seems I am misusing grep/egrep.   I was trying to search for strings in multiple line and could not find a match while I know that what I'm looking for should match. Originally I thought that my regexes were wrong but I eventually read that these tools operate per line (also my regexes were so trivial it could not be the issue).  So which tool would one use to search patterns across multiple lines? IE11 making background image text blurry Why is the node editor showing different kinds of nodes? I have been following  tutorial until I started adding nodes. The problem is that he has completely different nodes than I have. Even nodes that are created at start are different (I have Material and Output and he has Render Layers and Composite). Have I missed something or should I use different nodes than he? One adjective for two or more nouns Could we use one adjective for two nouns? Is the following sentence correct?     It has low speed and voltage.

Is there a straightforward way to change the summary/trimmed text to "full html" in Drupal 8?  There are workarounds such as creating separate body fields and using them as the summary but I am specifically asking about changing the text format of default summary/trimmed field of "Text (formatted, long, with summary)".  To put it another way, how to I add the CKEditor bar to the summary/trimmed text. I'm looking for an idiom or saying that I could use when people are focusing too much on small details and not seeing the big picture.  A couple that come to mind are "being penny-wise and pound foolish" and "rearranging deck chairs on the Titanic". However, the former doesn't fit what I'm thinking of because the present activity might not be wise. The latter implies too much about impending doom.  For example, let's say some company is spending all their time refining a small detail in their product, while ignoring a major opportunity shift in the industry. What phrase could I use there? What are the alternatives to Socket Programming? I was browsing around for programming troubleshooters, and I was wondering what the alternate would be for Socket Programming; if there is one. If a normal subgroup $N$ of order $p$($p$ prime) is contained in a group $G$ of order $p^n$,then $N$ is in the center of $G$. If a normal subgroup $N$ of order $p$($p$ prime) is contained in a group $G$ of order $p^n$,then $N$ is in the center of $G$.   I want to use induction to prove this:  It is trivial when $G=p(n=1)$, assume $G=p^n$, $N$ is a normal subgroup in $G$ with order $p$. Since $G$ is p-subgroup, $G$ has a normal subgroup $H$ with order $p^{n-1}$,according to assumption, $N \subset C(H)$. But I don't know how to go on, is $C(H)=C(G)$?Can induction work in this case? Are there recommendations or pitfalls for playing an archer cleric? In my 4E game, a player is going to try an elven cleric with a longbow (and a mace, just in case). She chose mostly ranged powers. Are there any caveats to playing such a character, or any builds that I could recommend for her? Can I run my CPU at 100% usage for a long time? Who was flying the Y-Wing when the Death Star exploded? Near the end of Star Wars IV: A New Hope, we see four spacecraft flying from the Death Star just moments before it explodes.     As you can see, there is the Millennium Falcon crewed by Han and Chewbacca, a pair of X-Wings which has to be Luke and Wedge, and then in the bottom corner, we see a Y-Wing. Who is this pilot and did he have any screen time to justify him actually existing in this moment? For as far as I can tell during the first trench runs, they were conducted by the Y-Wings and all of them seemed to have been destroyed during their run. So as I asked, who is flying this ship and how did survive to this moment? Automate Fixed Width Page, length > some minimum length, but only as long as needed I am trying to automate the solution proposed by egreg to  by hooking into \begin{document} and \end{document}.  So, egreg's solution works fine:  \documentclass{article} \def\MinimumPaperHeight{12cm} \usepackage{geometry} \geometry{paperwidth=\MinimumPaperHeight,paperheight=\maxdimen,margin=1cm} \usepackage{lipsum}  \begin{document} \setbox0=\vbox{ \lipsum[1-6] } \dimen0=\dp0 \pdfpageheight=\dimexpr\ht0+2cm\relax \ifdim\pdfpageheight&lt;\MinimumPaperHeight \pdfpageheight=\MinimumPaperHeight \fi \unvbox0\kern-\dimen0 \end{document}   But can't seem to get this to work:  \documentclass{article} \def\MinimumPaperHeight{12cm} \usepackage{geometry} \geometry{paperwidth=\MinimumPaperHeight,paperheight=\maxdimen,margin=1cm} \usepackage{lipsum} \usepackage{environ}  \NewEnviron{MyBox}{     \setbox0=\vbox{\BODY}% }{%     \dimen0=\dp0%     \pdfpageheight=\dimexpr\ht0+2cm\relax%     \ifdim\pdfpageheight&lt;\MinimumPaperHeight \pdfpageheight=\MinimumPaperHeight \fi%     \unvbox0\kern-\dimen0% }  \AtBeginDocument{\begin{MyBox}} \AtEndDocument{\end{MyBox}}  \begin{document} \lipsum[1-6] \end{document}   Hooking into \AtBeginDocument is per this solution on . msbuild, defining Conditional Compilation Symbols I'm possibly just blind, but is there a command line to specify conditional compilation symbols in MSBUILD?  I currently have this Line in my buildscript:  SET MSBUILD=C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\MSBuild.exe SET CONFIG=Debug %MSBUILD% /p:Configuration=%CONFIG% /p:OutputPath=..\..\output source\MyProject\MyProject.csproj   And I'd like to add a condition. In Visual Studio, i can just go into Project Properties => Build => Conditional compilation symbols, but I have not seen that option for msbuild?  Bonus Karma if you know if I can completely override all symbols already specified in the .csproj files to make sure that only the conditionals from my Buildscript go in.
