I'm reading the Stein-Shakarchi. In Chapter 3 there is a problem and I need to check my solution:  Show that there is no function $f$, such that is holomorphic, defined on the open unit disk that extends continuously to its border, and is equal to the function $g(z)=\frac{1}{z}$ in the border.   Here is my "solution":  Extend the domain of $f$ in such a way that now is $\mathbb{C}$. Now is $\frac{1}{z}$ if $|z|\geq1$, and is equal to $f(z)$ otherwise. By Morera's theorem every triangle has integral egual to 0 at the border of $\mathbb{D}$, so is holomorphic, in the other hand, f and the new g agrees on a set with accumulation point, so they must be equal. Finally, $g$ is not holomorphic in all $\mathbb{C}$, and $f$ is, so we get a contradiction.  Is something wrong here? Do you have any other solution?
How can one show there is no holomorphic function $f$ on the open unit disc $\mathbb{D}$ such that it extends continuously to $\frac{1}{z}$ on $\partial\mathbb{D}$? I mean $f$ takes value $\frac{1}{z}$ when $|z|=1$ and continuous here.  Thank you.
Troubleshooting advice for: -bash: cannot execute binary file: Exec format error I have a mining rig and am trying to run a program ./garlicoind  but I get this error:  -bash: ./garicoind: cannot execute binary file: Exec format error   Is this a common problem? What does it indicate? %AX = (%AH + %AL)  So why not %EAX = (%SOME_REGISTER + %AX) for some register %SOME_REGISTER? Can we use sine and cosine graphs for varying temperatures? I have been researching for a while looking for what to include more than just deriving the equation of Newton’s law of cooling and a website gave me inspiration by stating what if the temperature of the environment is changing (± C). In conclusion, I wasn’t sure if that person carried out the mathematical process in the right way and the only place I could ask for accurate information is here so please let me know what you think about the mathematical process he went for and if it is right or wrong. Thanks a lot. Website: Unwanted comma between author and year using citet command I've been using the biblatex package for a while, and since updating my TeX installation (post-el capitan upgrade) I have been experiencing the following.   If the following is typed:  Such and such has been said \citep[111]{citekey}.   The following text is displayed:  Such and such has been said (Author, 2016, p. 111).   And if the following is typed:  \citet[111]{citekey} has said such and such.   The following text is displayed:  Author, (2016, p. 111) has said such and such.   The citep command is working as I want it to, but I do not want a comma placed after the author's name when using the citet command. I would like it to display as follows:  Author (2016, p. 111) has said such and such.    If I use the \citeyearpar command, it is fine, but I would rather not have to type the author's name in manually.   Here is the command placed in the preamble:  \usepackage[backend=bibtex, style=authoryear-icomp, url=true, isbn=false, natbib=true, sortcites=true, block=space, pagetracker=false, loccittracker=constrict]{biblatex}   Here is an example of an entry in my bib file (made using BibDesk):  @article{poldrack2006, Author = {Poldrack, Russell}, Journal = {Trends in Cognitive Sciences}, Number = {2}, Pages = {59--63}, Title = {{Can cognitive processes be inferred from neuroimaging data?}}, Volume = {10}, Year = {2006}}   I have also tried changing the entry to the following:  @article{poldrack2006, Author = {Russell Poldrack}, Journal = {Trends in Cognitive Sciences}, Number = {2}, Pages = {59--63}, Title = {{Can cognitive processes be inferred from neuroimaging data?}}, Volume = {10}, Year = {2006}}   The bibliography entry appears as follows, and is fine:  Poldrack, Russell (2006). “Can cognitive processes be inferred from neuroimaging data?” In: Trends in Cognitive Sciences 10.2, pp. 59–63.

Given the following groups, what is the maximum possible order for an element for   (a) $S_5$ (b) $S_6$ (c) $S_7$ (d) $S_{10}$ (e) $S_{15}$  My book justifies the answer as          (a) The greatest order is $6$ and comes from a product of disjoint cycles of length 2 and 3          (b) The greatest order is $6$ and comes from a cycle of length $6$      The other answers were justified exactly the same way, that is (c) 12, (d) 30, (e) 105  I do not understand how in (a) we even got the number "6" from $S_5$ and what disjoint cycles they are referring to. Could someone at least justify one for me? shortcut for commands I use following commands very often, and they're too long.  sudo /etc/init.d/kerio-kvc start sudo /etc/init.d/kerio-kvc stop   how can I create a shortcut command for them? something like sudo kerio start or sudo kerio stop How do I copyright my website?

Why would I want to install a snap if I can install via apt instead? How to train students to write high-quality research papers? As someone supervising postgrad students, I wonder what is the best way to train these students to write high-quality research papers?    The best way seems to be through coauthorship but ...  On the one hand I can be hands-off and rather give them feedback as best as I can but let them do most of the work themselves, sort of like a "sink or swim" strategy.  On the other hand I can be hands-on and rewrite the paper (or large parts of it) and hope that they learn from the example I give.  On the one hand I want them to learn to write papers without me some day and I want them to learn as quickly as possible to take load off me.  On the other hand I want us to publish in the best place possible with as little stress as possible.  On the one hand I want them to see the peer review comments from what they themselves have written.  On the other hand I do not want them to be discouraged by the peer review system early on and do not want to submit papers I know we could have written better.  On the one hand I want them to get confidence by being published and presenting work at good venues.  On the other hand I wonder if they need to get there themselves to get that confidence boost.    At the moment I'm very hands on. There's a few factors for this: I don't like submitting papers that are not up to a certain standard, I'm a native English speaker in a non-English speaking country with non-native speaking students, publications are a high priority for me, etc.  But recently a friend/colleague warned me that I should not be so hands-on with the writing of the papers of my students. He pointed to recently graduated researchers in my area that published good work as students but who struggled after leaving their PhD supervisor saying their supervisor did them no favours in the long term ... that by being so hands on, while the students have success getting published and so forth with me, I'm not really doing the most important thing a good supervisor should do: making myself obsolete.    My question is how to train students to write good research papers and in what ways can I balance being hands-on and hands-off?  I'm also interested in methods not directly involving coauthorship.

How to create a site in a sitecollection on a remote SPServer using C# I am currently trying to write a Dynamics CRM 2011 plugin that creates a new SharePoint 2010 site (within an existing site collection) for every account that is created. I have the code for creating a library, which uses the following methods:          private static ClientContext CreateSharePointConnection()         {             try             {                 Uri spSiteUrl = new Uri(Constants.SharePointSiteName);                 using (ClientContext spcontext = new ClientContext(spSiteUrl))                 {                     spcontext.Credentials                         = new System.Net.NetworkCredential(Constants.UserName                             , Constants.Password, Constants.DomainName);                     return spcontext;                 }             }             catch (Exception ex)             {                 throw new Exception("SharePointMethods.CreateSharePointConnection (General Exception: "                     + ex.Message + ")");             }         }  private static void CreateDocumentLibrary(ClientContext _clientContext             , string _documentLibraryName, string _documentLibraryDescription)         {             try             {                 Web web = _clientContext.Web;                 _clientContext.Load(web);                 _clientContext.ExecuteQuery();                 ListCreationInformation lci = new ListCreationInformation();                 lci.Title = _documentLibraryName;                 lci.Description = _documentLibraryDescription;                 lci.TemplateType = 101;                 List newDocumentLibrary = web.Lists.Add(lci);                 newDocumentLibrary.ContentTypesEnabled = true;                 newDocumentLibrary.Update();                 _clientContext.ExecuteQuery();             }             catch (Exception ex)             {                 throw new Exception("SharePointMethods.CreateDocumentLibrary('" + _documentLibraryName                     + "') (General Exception: " + ex.Message + ")");             }         }   So I would like to write a method CreateSite instead of CreateDocumentLibrary. However, all examples I can find on the web for programmatically creating a Site are using SPSite, SPWeb, etc. Something like this:  private static void CreateSite(string _siteName, string _siteDescription) {     try     {         SPSite site = new SPSite(Constants.SharePointSiteName);         SPWeb web = site.OpenWeb();         SPWebCollection wc = web.Webs;         string siteTemplate = web.WebTemplate;         wc.Add(Constants.SharePointSiteName, _siteName, _siteDescription, 1043, siteTemplate, true, false);     }     catch (Exception ex)     {         throw new Exception("SharePointMethods.CreateSite('" + _siteName             + "') (General Exception: " + ex.Message + ")");     } }   However this is NOT a solution for my problem, because the SPSite, SPWeb, etc. only work on the local machine and I want to create a Site from a remote (in my case CRM) server. Anyone got an idea how to solve this.  PS: Code might still contain memory leaks, so please be carful when you use it for production purposes!
