"Populate an array using dynamic variables names in Powershell",

"Azure Web Role-Some files are not being added to cspkg file",
"Finally after days of trial and error, I managed to get an existing MVC project converted into Azure Web Role. Deployed and it works, mostly. But my biggest issue is that the cspkg is missing some files that are part of the MVC project (they are listed in csproj). It appears that some files are being left out randomly. For example, if a folder has 4 files, I see only one of that included in the cspkg. Is there a way to force inclusion of these files other than listing them in csproj. I noticed that Visual Studio web role deployment process goes through the list of files in csproj. When a file listed in csproj is not found, cspkg creation throws errors. So my assuption was that if a file was listed in csproj and if the file actually exists, it should find its way to cspkg."

"is it legit to establish a relationship between two subclasses which sharing the same superclass (IS-A relationship)?",
"I have a question regarding a project I am doing and hope you could provide some help:)\n\nThe police were looking for a murder suspect after a person was shot and killed yesterday. The only clue is that the victim has left a note with five people's names on it, and the police needed to find these five people's information by searching on the citizen database (name is not unique so there may be more than five results. To uniquely identify someone you need the citizen ID). After finding the murderer, the police need to make changes to the murderer's criminal record. I am wondering how could I do this?\n\nSince the entity Victim and the entity Murder_suspects both have the same attributes as the entity Citizen, my original plan was to make victim and murder_suspects become two subclasses sharing the same superclass(citizen), that is to say, victim ISA citizen and murder_suspects ISA citizen. However, I am not sure if it is legit to establish a relationship between two subclasses which share the same superclass (IS-A relationship). Also, I think the primary key of murder_suspects should be citizen.name instead of citizen.id, but I don't think that the subclass's primary key could be different from its superclass's primary key. I am wondering if anyone could help with my confusion and give me some suggestions, thanks in advance:)!\n\nP.S. To make it more clear, the entity citizen has the following attributes: id, name, phone_number, address, criminal_record, etc.\n\nMany thanks for any help anyone is able to provide:)"

"Computed column, or update column by trigger to keep statistics",
"For every user, our application calculates some statistics, like how many times they logged in or how many answers they got wrong in the quiz, ... it can be all sorts of things. The app runs on SQL Server and .NET Entity Framework 6.1\n\nRight now, the statistics are calculated on demand but as the user base grows, this makes the reporting part of the application ever slower.\n\nWe were wondering about either using computed columns (either persisted or not persisted) or use a trigger to store these values with the user.\n\nHow would you go about doing this? It seems to me that computed columns may be easier to implement, but they would get recalculated every time I read the User from the table, which may not be very much faster than what we're doing now. Since we would fit an entire SQL query into the computed column, persisting the column does not seem a right fit either (how will SQL Server deduce that it should update the calculation?).\nA trigger on certain actions seems to be a more logical fit for me.\n\nFor the sake of the argument, suppose all the calculated statistics are count(*) and sum(*) of values in other tables and nothing more interesting than that."

"Interweaving vector of binary representations in C++",
"I have a templated function in C++ called weave which takes two unsigned chars and interweaves their binary expansions and returns a unsigned short. It can also take two unsigned shorts and interweaves their binary expansions to return an unsigned long. Here is what I wrote:\n\ntemplate<class Typeout, class Typein>\nTypeout weave(Typein lhs,Typein rhs)\n{\n//Need to check that Typeout contains enough storage to contain 2*Typein:\nassert(sizeof(Typeout)>=2*sizeof(Typein));\n\nTypeout weaved = 0;\nfor(int k=0;k<sizeof(Typein)*8;k++)\n{\n //weave in the kth element of rhs and lhs.\n weaved |=(Typeout(rhs & (Typein)(1<<k)) << k)| (Typeout(lhs & (Typein)(1<<k)) << (k+1));\n}\nreturn weaved;\n};\n\n\nNow I'm having trouble with weaving together vectors. I want to write a function called weave that given a vector of chars interweaves all of their binary expansions and returns this. For instance given a vector of unsigned chars of length 4 it should interweave their binary expansions and return a representation of this. I want this to work for vectors of chars of length greater than 8 so I can no longer keep them in a unsigned long long. I guess I need to return a vector?? But I'm not sure how to cut the resulting binary expansion up.\n\nI'm new to C++ so please feel free to correct the code or give me advice on it. \n\nThanks in advance."

"Performance of DrawingVisual vs Canvas.OnRender for lots of constantly changing shapes",
"I'm working on a game-like app which has up to a thousand shapes (ellipses and lines) that constantly change at 60fps. Having read an excellent article on rendering many moving shapes, I implemented this using a custom Canvas descendant that overrides OnRender to do the drawing via a DrawingContext. The performance is quite reasonable, although the CPU usage stays high.\n\nHowever, the article suggests that the most efficient approach for constantly moving shapes is to use lots of DrawingVisual instances instead of OnRender. Unfortunately though it doesn't explain why that should be faster for this scenario.\n\nChanging the implementation in this way is not a small effort, so I'd like to understand the reasons and whether they are applicable to me before deciding to make the switch. Why could the DrawingVisual approach result in lower CPU usage than the OnRender approach in this scenario?"

"From the REST API of the elasticsearch (version 2.4.4), we can use multiple fields in exists query as:\n\n{\n \"query\": {\n \"exists\": {\n \"field\": [\n \"field1\",\n \"field2\",\n \"field3\"\n ]\n }\n }\n}\n\n\nBut I couldn't find the equivalent Java API for the same. The java class ExistsQueryBuilder takes only one field as the constructor. So, isn't there really any Java API for it? So, the only way to do it from Java API is using bool-should of exists query for each field?"

I saw in some tutorials that first I must obtain the current layout margins or something like that, but I am not sure why it's so complicated, in Swift I just modify the properties of each margin.\n\nIs there an easy way to achieve this or in case there isn't what would be the easiest way to do this?\n\nUPDATE - Added code in the Adapter\n\nThis is the code I have in my adapter for this specific ImageView:\n\noverride fun onBindViewHolder(holder: AnoViewHolder, position: Int) {\n ...\n if(respec.nombre_icono_signo != \"\" && respec.imagen_luna != \"\") {\n val layoutParamsLuna = holder.view?.imagen_luna.layoutParams as RelativeLayout.LayoutParams\n layoutParamsLuna.setMargins(1, 8, 15, 8)\n holder.view?.imagen_luna.layoutParams = layoutParamsLuna\n }\n ...\n}\n\n\nThe thing is that this does nothing and my theory is that the setMargins function accepts left and right margins, not start and end margins."

"Java - how to obtain an interleaved iterator/collection",
"Let's say we receive strings from 3 producers asynchronously. Once a certain amount of these objects have been received I want to iterate over them in an interleaved manner, that is, if receiving the following strings:\n\n\"a1\" received from A,\n\"a2\" received from A,\n\"c1\" received from C,\n\"a3\" received from A,\n\"b1\" received from B,\n\"b2\" received from B,\n\n\nI'd like the \"interleaved\" iterator to return the strings as if we were iterating over the following list:\n\nList<String> interleavedList = {\"a1\", \"b1\", \"c1\", \"a2\", \"c2\", \"a3\"},\n\n\nSo far I've created one List<String> for each producer, and then I'm \"iterating\" over all the strings by working with the 3 list iterators (with a List<Iterator<String>>). This works fine but I think there is a simpler way... Maybe by directly constructing the interleaved list while receiving the strings? but I don't see which Collection or which Comparator to use...\n\nNote that I'm not so much interested in creating one list for each producer and then merging the 3 lists in a 4th interleaved list, as this will probably not be time-efficient."

"MongoDB/Mongoid Tree Structure",
"I'm currently speccing out the architecture for a project. Its on a fairly tight timeline, will need to support a few hundred thousand users fairly soon after launch, and its business logic and model are tied tightly to an extended tree structure. I know I can do this in Mongo in a variety of ways as listed in the documentation. The best seems to be a hybrid approach of a parent field + one of the following: materialized path or array of ancestors. Right now my test implementation is using an array of ancestors, with the array being populated with the ObjectIds of the related documents. On a sample dataset some of the query times are a tad higher than I would like, but still acceptable. Does anyone have any tips for optimizing this structure? I tried the full materialized path, but once my tree went past 10 or so levels performance really seemed to crash. All my test data sets were 500k documents. The other components that might be relevant is a web front-end powered by Rails, using Mongoid for the majority of the interface between Rails and Mongo."

In this menu, I have several submenus which I would like to be expanded to the right when the mouse hovers the parent item.\n\nHere is the html\n\n <div id=\"leftmenu\">\n <ul>\n <li><a href=\"\">Item</a></li>\n <li><a href=\"\">item</a>\n <ul>\n <li><a href=\"\">SubItem</a></li>\n <li><a href=\"\">SubItem</a></li>\n </ul>\n </li>\n <li><a href=\"\">Item</a>\n <ul>\n <li><a href=\"\">SubItem</a></li>\n <li><a href=\"\">SubItem</a></li>\n <li><a href=\"\">SubItem</a></li>\n </ul>\n </li>\n <li><a href=\"\">item</a>\n <ul>\n <li><a href=\"\">SubItem</a></li>\n <li><a href=\"\">SubItme</a></li>\n <li><a href=\"\">SubItem</a></li>\n </ul>\n </li>\n <li><a href=\"\">item</a></li>\n <li><a href=\"\">Item</a></li>\n </ul>\n </div>\n\n\nAnd here is my CSS\n\n #leftmenu {\n float: left;\n margin: 30px;\n font-weight: bold;\n background: linear-gradient(#ffeb99, #ffe066);\n border: 0;\n border-radius: 10px;\n }\n\n #leftmenu ul {\n position: relative;\n border-radius: 10px;\n display: inline-block;\n }\n\n #leftmenu ul ul {\n display: none;\n background: #e7c702;\n }\n\n #leftmenu ul li:hover > ul {\n display: inline-block;\n width: 100%;\n height: 100%;\n position: absolute;\n left: 100%;\n }\n\n #leftmenu ul li a {\n padding: 15px 30px;\n display: block;\n color: #757575;\n text-decoration: none;\n font-size: 15px;\n text-transform: uppercase;\n }\n\n\nMy problem is when I hover the mouse to an item that has subitems, the subitems appear but it down not in the same line as its parent item. Instead, it appears in the same line of the item the item I'm hovering. I'm learning CSS so I don't want to use any JavaScript in this case.\n\nPlease help me with this.\nSorry if I format something wrong since this is my first post here.\nThank you"

"SqlAlchemy can't determine join condition",

The problem I have is when I go to retrieve the data, I want to be able to get the values(tCableSet row) along with the rest of my tStepVoltage table via a relationship, however I'm not sure how to go about this since I don't have a field in my tCableSet that can directly be linked via relationship to my tStepVoltage. I basically just needed the tCableSet for normalization"

"Using form in multiple locations -- controller should redirect to different location depending on where the request came from",
"I have a form to add a staff member.\n\nThe form is first used when an account is created in a sequence of view to help the user setup their account.\n\nIt is then used in a different place once the account has already been setup.\n\nThese two use different layouts and controllers, so have different URLs. However, when the form is submitted, they both currently call the same controller#create. Now, if the form is submitted form the setup area, it should redirect to one URL after the create action is called. It should go to a different location if it's called from the main application UI (non-setup).\n\nWhat's the simplest way to set this up?"

"SQLBulkCopy: Does Column Count make difference?",
"I try to search but didn't found answer to relative simple thing. I have a CSV, that doesn't have all the column as in my database table, as well as it miss the auto increment, primary key in CSV too. \n\nAll I did is I read CSV into the DataSet, and then run a traditional SQLBulkCopy code to read the first table of dataset to database table. But it give me following error:\n\nThe given ColumnMapping does not match up with any column in the source or destination.\n\nMy code for bulkcopy is \n\nusing (SqlBulkCopy blkcopy = new SqlBulkCopy(DBUtility.ConnectionString))\n{\n\n blkcopy.EnableStreaming = true;\n blkcopy.DestinationTableName = \"Project_\" + this.ProjectID.ToString() + \"_Data\";\n blkcopy.BatchSize = 100;\n foreach (DataColumn c in ds.Tables[0].Columns)\n {\n blkcopy.ColumnMappings.Add(c.ColumnName, c.ColumnName);\n }\n\n blkcopy.WriteToServer(ds.Tables[0]);\n blkcopy.Close();\n}\n\n\nI add Mapping to test, but it doesn't make difference to remove mapping part. If we remove mapping that it try to match column in order and since column are different in count they end up mismatch datatype and lesser column values etc. Oh yes the column names from CSV does match that from Table, and are in same case.\n\nEDIT: I change the mapping code to compare the column name from live DB. For this I simply run a SQL Select query to fetch 1 record from database table and then do following\n\nforeach (DataColumn c in ds.Tables[0].Columns)\n{\n if (LiveDT.Columns.Contains(c.ColumnName))\n {\n blkcopy.ColumnMappings.Add(c.ColumnName, c.ColumnName);\n }\n else\n {\n log.WriteLine(c.ColumnName + \" doesn't exists in final table\");\n }\n}"
