I am working through a (simple)  in a Console Application just to learn the basics of Database Migrations in EF. All of the other Tables and Columns are being generated fine but this one Column is being created with angle brackets around it in SQL Server Express ( '[Content]' rather than 'Content').  I can't see any thing in the class declaration   public class Post     {         public int PostID { get; set; }         [MaxLength(200)]         public string Title { get; set; }         public string Content { get; set; }          public int BlogID { get; set; }         public Blog Blog { get; set; }      }   the Migration file   public partial class AddPostClass : DbMigration {     public override void Up()     {         CreateTable(             "dbo.Posts",             c =&gt; new                 {                     PostID = c.Int(nullable: false, identity: true),                     Title = c.String(maxLength: 200),                     Content = c.String(),                     BlogID = c.Int(nullable: false),                 })             .PrimaryKey(t =&gt; t.PostID)             .ForeignKey("dbo.Blogs", t =&gt; t.BlogID, cascadeDelete: true)             .Index(t =&gt; t.BlogID)             .Index(p =&gt; p.Title, unique: true);          AddColumn("dbo.Blogs", "rating", c =&gt; c.Int(nullable: false));     }      public override void Down()     {         DropForeignKey("dbo.Posts", "BlogID", "dbo.Blogs");         DropIndex("dbo.Posts", new[] { "Title" });         DropIndex("dbo.Posts", new[] { "BlogID" });         DropColumn("dbo.Blogs", "rating");         DropTable("dbo.Posts");     } }   or in the generated SQL script (I used the -Verbose flag)  CREATE TABLE [dbo].[Posts] ( [PostID] [int] NOT NULL IDENTITY, [Title] [nvarchar](200), [Content] [nvarchar](max), [BlogID] [int] NOT NULL, CONSTRAINT [PK_dbo.Posts] PRIMARY KEY ([PostID])   )  which would indicate why this particular column is being generated with the angle brackets included?  Can anyone help?
I've noticed that Visual Studio 2008 is placing square brackets around column names in sql. Do the brackets offer any advantage? When I hand code T-SQL I've never bothered with them.  Example:  Visual Studio:  SELECT [column1], [column2] etc...   My own way:  SELECT column1, column2 etc...
Currently selected indicator's colour in flag summary and help pages, can be the same as the site's colour code Our iPad is locked and we're not sure of the Apple ID / iCloud password This question is actually related to my earlier question ("").  The fact that objects move a lot in the universe and that the universe is expanding, can imply that gravity is a repulsive force that increases with distance.. so the farthest objects repel us more.  This can still explain several existing observations, e.g., why does the apple fall?   Motion is the result of such repulsion. Two objects unlucky enough not to be moving relative to each other get squished due to the repulsion of the rest of the universe  around them. The earth repels the apple less than the stars so it is pushed towards the earth.   Furthermore, it can explain the expanding universe without the need for dark energy.  This could be demonstrated in a thought experiment. If we take a lot of same-charge particles (with small mass) such as electrons and lock them in a large box at a low enough temperature. The mutual repulsion of the particles may cause similar motion as if due to gravitational attraction.   Another experiment would be to measure the slight changes in our weight during day and night when the sun and earth align (if their masses are large enough to detect the feeble change in repulsion).   [EDIT: the question in the original form may not have been clear. It is "can we model".. with a yes/no answer and why (not). If downvoting, please justify. Proofs of consistency for two formal systems Do there exist two formal systems, $F_1$ and $F_2$, such that $F_1$ proves $F_2$ is consistent and $F_2$ proves $F_1$ is consistent?  Would these proofs bypass Gödel's Second Incompleteness Theorem?  By "consistent", I mean the formal system does not prove $X$ and NOT $X$. What has Ramsay done to Theon torture-wise?

Source link: From 2012 onward the SQL Server docs show they support  which I'm trying to use instead of a LIMIT.  The following works fine in PostgreSQL to sample a result set,  SELECT * FROM ( VALUES (1),(2),(3) ) AS t(x) OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY;   However, with SQL Server, I get  Msg 153, Level 15, State 2, Line 4 Invalid usage of the option FIRST in the FETCH statement.   What's going on here? Does SQL Server support the standardized OFFSET .. FETCH? Does Linux have the capability to use "junctioned" symbolic links? I'm not sure if this is an actual term or not, so let me explain the concept.  I have a git repository containing all my configuration dot files in ~/dotfiles. I use symbolic links into this directory in order to "activate" them. For example, by executing ln -s ~/dotfiles/bash/bash_profile ~/.bash_profile to produce the link:  ~/.bash_profile -&gt; ~/dotfiles/bash/bash_profile   However, I find myself in a situation where I want to combine the contents of multiple files. For example, I want the ~/.bash_profile symbolic link to point to two separate files, one for each project. E.g.:  ~/.bash_profile (1) -&gt; ~/dotfiles/bash/bash_profile (2) -&gt; ~/dotfiles/proj/bash_profile   I know I can simply concatenate the two files (e.g., cat ~/dotfiles/{bash,proj}/bash_profile &gt; ~/.bash_profile), but if I can do the same thing with symbolic links, I would prefer to.  I imagine that if such a feature exists (Nix is pretty huge), then under the hood it would have to map the two different files together, hiding all sorts of complexities under the hood (mapping file offsets of all non-first "mapped" files, locking all files when writing to the junctioned symbolic link, etc, etc).  If such a feature doesn't exist, are there are plans to implement it? How to switch from Resident visa to Tourist visa status in the Schengen area? Using InDesign CS6, how can I simultaneously edit A4 and A5 versions of a poster? I'm on Adobe Creative Cloud, so I have the latest InDesign, and I'm attempting to design a poster for my choir's next concert. Traditionally, I've done this in Photoshop, in two separate files, however I've recently started using InDesign after converting to it to create wedding albums through Blurb.  I've created an A4 document, and created an alternate-layout for it in A5. I've then lined them up side-by-side, and I've added a black frame to the A4 page, to act as the black background for my page (by the way, feel free to advise on better ways to do this).  My assumption is that I've failed to understand how this works, as I was hoping that I'd magically get a black frame on the A5 version, and that I could use liquid layout to get this to automatically scale (along with all other elements), in order to create the two versions simultaneously.

How to to calculate the hash of an unordered set Suppose I have a set of elements, with known hash (e.g. SHA-2). How can I calculate the hash of the set? With it I mean an unordered set, so the order of elements is undefined and shall not play any role in determining the hash of the set.  In theory any commutative operation applied to the hashes should be fine, but I have the strong feeling that XORing all of them together is quite unsafe. An attacker could add an element to the set to produce a hash collision, although finding an element with that wanted hash is as hard as breaking the hash of the whole set.  Anything better solution than the trivial one of sorting the elements into a list, calculating their hashes and then calculating the hash of the hash list?  I think Merkle trees can't help here if they are based on some sort of ordering of the elements. Primary ideals of $\mathbb{Z}$ Let $R=\mathbb{Z}$ I must prove that      In $\mathbb{Z}$ the primary ideals s are precisely the ideals $(p^k)$ where $p$ is a prime number and $n\ge 1$.   $$$$ The definition of primary ideal.     Definition. An ideal $I$ of the ring $R$ is called primary if for all $a,b\in R$ $$(ab\in I\quad\text{and}\quad a\notin I)\Rightarrow b^n\in I, \text{for some positive integer $n$}.$$   Therefore I must prove that      $$(n)\;\text{is primary in}\;\mathbb{Z}\iff n=p^k, k\ge1,p\ge2,\;\text{where}\;p\;\text{is a prime}.$$   Proof ($\Leftarrow$) We suppose that $n=p^k$ for same prime $p$ and $k\ge 1$. Let $a,b\in\mathbb{Z}$ such that $ab\in(p^k)$ and $a\notin (p^k)$. Then $p^k\nmid a$, but $p^k \mid ab$ I no longer know how to proceed.  $(\Rightarrow)$ Let $(n)$ a primary ideal and we suppose for absurd that $n$ is not a power of a prime, then? how could I proceed?  Now, let $ab\in (p^k)$ with $a\notin(p^k)$, then $p^k\mid ab.$ Can I conclude that $p^k\mid b$?   How can I set up the other implication?
