Nexus 7 2013 error upgrading to 5.0.2 OTA I updated to 5.0.1 via OTA sometime ago, and it worked fine. Now I got a notification that 5.0.2 is ready but when Android shuts down to install update it returns error (with no other message. My Nexus 7 is rooted but has the stock recovery.  Is there an easy fix that doesn't require factory reset or installing recovery?
I was working on historical data looking for anomalous patterns that we would not expect to occur at random. I'd like to create a scheme to analyze data and markets to test for statistical significance and consistency over time.  Question : Are there some tools we could use to evaluate the nonrandomness of a database? What do we use usually to say that something is random or not (statistically)? Figure we work with change in some value over time. Short circuit or disconnect to bypass a compressor How do I set exposure with a manual flash? I recently got an old Canon AE-1 film camera back in working order. I'd like to use my modern 430EXII Speedlight flash with it, however since there is no TTL metering, I have no idea how much the flash will affect the exposure of my shot (note that I have confirmed that the AE-1 will trigger the flash). I'd rather not discover that my shots were either blown out or way to dark after going through several rolls of film.  Are there any basic rules-of-thumb or basic calculations for anticipating how much a burst from the 430EXII will affect the exposure of a subject at various distances? How can I convert audio from MP4 or FLV video files to mp3? Is there an application that allows me to extract the audio from a MP4 or FLV video file and store it as an MP3 file for use in a portable media player? In Episode 1: The Phantom Menace, Anakin's mother, Shmi, said that he does not have a father, although it seemed to me that she doubted that.  Is there a canonical answer as to who Anakin's father is?  If so, who? Why does network ad URL from SO to history.SE mention Ask Ubuntu? Today, I was on Stack Overflow when I noticed an interesting ad pointing to history.SE (actual square ad, not just Hot Network Questions).  The link in the ad was:    which resolves to:  https://history.stackexchange.com/questions/23946/what-were-greek-and-roman-sails-made-from?utm_medium=ad&amp;utm_source=http-askubuntu-com-questions-471178-converting-hundreds-of-jpg-to-pdf-using-te&amp;utm_campaign=history.stackexchange.com-promo&amp;utm_content=23946  (link form for conveniece: )  The confusing part os the URL is: utm_source=http-askubuntu-com-questions-471178-converting-hundreds-of-jpg-to-pdf-using-te. The ad is from SO to history.SE, it doesn't have anything to do with Ask Ubuntu, so why does it appear in the URL? Is this a bug?

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! Can all fundamental forces be fictitious forces? After reading many questions, like   and , I wonder:   Is it possible to consider the other fundamental forces too, the electroweak interaction and the strong interaction or ultimately the unification of these, to be fictitious forces like gravity in the framework of general relativity?   If we want a final unification of all fundamental forces, hasn't this feature of gravity to become a feature of the other forces as well? Proof that $\mathrm{ker}(f^*) = \mathrm{im}(f)^{\perp} $ Where $ f: V \rightarrow V  $ is a linear operator on an inner product space $V$, I'm trying to show that $$ \mathrm{ker}(f^*) = \mathrm{im}(f)^{\perp} $$  i.e. the Kernel of the adjoint is equal to the orthogonal complement of the image of f.  I taking the inner product of $f(v)$, where $v \in V$  and an arbitary element of the kernel, $k \in \mathrm{ker}(f^*) $  $$\langle f(v), k\rangle = \langle v, f^*(k)\rangle = \langle v, 0\rangle = 0$$  And then taking the inner product of $f(v)$ with $w$, where $w \in  \mathrm{im}(f)^{\perp}$  By definition  of the orthogonal complement to the image of f,   $$ \langle f(v), w\rangle = 0 $$  My question is, now that we have   $$ \langle f(v), k\rangle = \langle f(v), w\rangle = 0 $$  What can we conclude? I would like to conclude that because $w$ and $k$ are arbitary elements of their respective subspaces, that these must be equal, i.e. $ \mathrm{ker}(f^*) = \mathrm{im}(f)^{\perp} $  However, I am not sure this is mathematically sound, is that conclusion valid or are there any technical barriers or additional statements that would have to be made to make that watertight?

An .mov video that is upside down in Windows appears right side up in OSX Do universities hire graduates from lesser universities Recently, someone analyzed  and found that over half of the professors at the top 51 universities graduated from a top 10 university.  have also brought this up. From my personal observations, most schools do hire graduates from better ranked schools.  Is this because of the competitive job market? We have so many good applicants, we have to narrow it down some how! Or is it simply that these schools produce the most PhDs? Has this always been the case? How rare are exceptions to this? I know of a few people who graduated from a top 75 school and got hired at a top 50 school. But what about bigger gaps? The top 10 schools seem to just swap graduates, do they ever hire from a 50+ ranked school?  Update 2018: I have accepted a tenure-track position at a top 75 department at an R1 university immediately after graduating from an unranked department at an R2 university. It does happen! This may or may not generalize to other fields and countries. Falsely accused witch befriends transforming dragon she was to be sacrificed to Story is in a medievalish setting and starts with a woman who has been falsely accused of being a witch being taken by 2 men to be sacrificed to a dragon.  She ends up befriending the (male) dragon, who is able to transform into various forms, including human, and can speak only the language of whatever form he is in. e.g. can speak English in human form, but can't in dragon form.  He needs to return to his dragon form every day at sunrise or he dies.  Contact with iron or steel causes him pain and prevents him from transforming.  Near the end of the book, he's been put in handcuffs by one of the two men from the start and the woman has to get the assistance of the other one (village blacksmith?) to remove them before sunrise, which they manage to do just in time.  I think I read it maybe 10 years ago.    I also remember it was a very short book, probably only about 100 pages. Command to move a file to Trash via Terminal I would like to know if there is a command I can issue in a terminal so I do not classically remove (rm) the file, but instead move it to trash (i.e. Nautilus Move to Trash behavior).  In case there is such a command, I would also be interested in knowing what it is. How to mount and unmount hard drives under Windows (the unix way) Close popup doesn't appear after editing the question without refreshing the page Seems like a bug:  The user:   Edits a question Then, he decide to close it. Clicks on the Close button. The popup doesn't appear. Refreshes the page. Click on the close button. The popup appears.   After editing in the link appears a hash: #. But I don't think that this is the problem because if I add the hash without editing the close popup appears.  It's minor, but I think that is good to be reported and solved.

I want to install a new Solid State Drive (SSD) into the Mac. Can I just build in the SSD, start the MacBook in Recovery Mode and install OS X from there on?  After reading a lot on the internet I still have some doubts…  My HDD crashed, I can't repair it using disk utility or the fsck methods as mentioned on the internet.  According to  it should be possible.  I know how to replace the HDD with the SSD. I would go for the Samsung 850 EVO SSD - 500GB. My Mac is a MacBook Pro Mid 2012, model A1278. It is well known from Noether's Theorem how from continuous symmetries in the Lagrangian one gets a conserved charge which corresponds to linear momentum, angular momentum for translational and rotational symmetries and others.  Is there any elementary argument for why linear or angular momentum specifically (and not other conserved quantities) are conserved which does not require knowledge of Lagrangians? By elementary I mean, "if this is not so, then this unreasonable thing occurs".   Of course, we can say "if we want our laws to be the same at a different point in space then linear conservation must be conserved", but can we derive mathematically the expression for the conserved quantity without using the Lagrangian?  I want to explain to a friend why they are conserved but he doesn't have the background to understand the Lagrangian formalism.
