[ "Duplicate Rows when Data Binding with LINQ to Entities", "I have problems binding both a telerik RadGrid and a plain vanilla ASP.NET GridView to the results of the following LINQ to entities query. In both cases the grids contain the correct number of rows, but the data from only the first handful of rows is duplicated in all the other rows. I'm directly assigning the return value from this code the the DataSource property on the grids.\n\npublic IEnumerable<DirectoryPersonEntry> FindPersons(string searchTerm)\n{\n DirectoryEntities dents = new DirectoryEntities();\n return from dp in dents.DirectoryPersonEntrySet\n where dp.LastName.StartsWith(searchTerm) || dp.Extension.StartsWith(searchTerm)\n orderby dp.LastName, dp.Extension\n select dp;\n}\n\n\nADDED: This is the alternate plain ADO.NET code that works:\n\n DataTable ret = new DataTable();\n using (SqlConnection sqn = new SqlConnection(ConfigurationManager.ConnectionStrings[\"WaveAdo\"].ConnectionString))\n {\n SqlDataAdapter adap = new SqlDataAdapter(\"select * from DirectoryPersonList where LastName like '\" + searchTerm + \"%' order by LastName \", sqn);\n sqn.Open();\n adap.Fill(ret);\n }\n return ret;\n\n\nMORE: \n\n\nThe query sent to SQL Server by LINQ works. \nIterating the LINQ query results before returning them results in the same duplications.\nIterating the LINQ results in the calling method, before binding, results in the same duplications.\n\n\nUPDATE:\nBased on the very logical and fitting advice from Marc Gravel below, I found that the EF designer had made a very uneducated guess at an Entity Key for my entity class, the first field in its list of fields, Department, of which there are only about seven entries shared across all other records. \n\nThis is indeed the cause of the duplication. If only I could change or remove the entity key, but this EF designer with all the business logic of an Etch-a-Sketch is admirably committed to repeating it's retarded choice of key while laughing at me locked outside begging to change the key." ]

[ "What does seq actually do in Haskell?", "From Real World Haskell I read\n\nIt operates as follows: when a seq expression is evaluated, it forces its first argument to be evaluated, then returns its second argument. It doesn't actually do anything with the first argument: seq exists solely as a way to force that value to be evaluated.\n\nwhere I've emphasised the then because to me it implies an order in which the two things happen.\nFrom Hackage I read\n\nThe value of seq a b is bottom if a is bottom, and otherwise equal to b. In other words, it evaluates the first argument a to weak head normal form (WHNF). seq is usually introduced to improve performance by avoiding unneeded laziness.\nA note on evaluation order: the expression seq a b does not guarantee that a will be evaluated before b. The only guarantee given by seq is that the both a and b will be evaluated before seq returns a value. In particular, this means that b may be evaluated before a. […]\n\nFurthermore, if I click on the # Source link from there, the page doesn't exist, so I can't see the code of seq.\nThat seems in line with a comment under this answer:\n\n[…] seq cannot be defined in normal Haskell\n\nOn the other hand (or on the same hand, really), another comment reads:\n\nThe 'real' seq is defined in GHC.Prim as seq :: a -> b -> b; seq = let x = x in x. This is only a dummy definition. Basically seq is specially syntax handled particularly by the compiler.\n\nCan anybody shed some light on this topic? Especially in terms of:\n\nWhat source is right?\nIs seq's implementation really not writable in Haskell?\n\nIf so, what does it even mean? That it is a primitive? What does this tell me about what seq actually does?\n\n\nIn seq a b is a guaranteed to be evaluated before b at least in the case that b makes use of a, e.g. seq a (a + x)?" ]

The only method to fill the sides is using either a solid color or gradient as far as I'm concerned. To make things more exciting, I'd really love to implement texture mapping using a simple bitmap.\n\nThe point is that I can hardly find any articles or code samples on the subject of image manipulation in JavaScript. Moreover, image support in HTML5 canvas seems to be restricted to cropping.\n\nHow could I go about stretching a bitmap so that a rectangular bitmap can fill up a unregular cube face? In 2D, a projected square cube face is, due to perspective, not of a square shape, so I'll have to stretch it to make it fit in any quadrilateral.\n\nHopefully this image clarifies my point. The left face is now filled up with a white/black gradient.
