"expressing constraints in relational algebra",

"How to follow a URL in R",
"Sorry for the bad title but I don't know how else to phrase \"follow\". \n\nI'm looking to remotely download a csv file from a website. I could do this by clicking the download button using RSelenium, but I've found that there's a direct link that will initiate the download for me. I.e. I could go to https://www.fake-website-url.com and click the download button, or I could just enter https://www.fake-website-url.com/exportcsv into my browser and it would automatically download.\n\nI try not to use RSelenium whenever I can help it since it's clunky, but I'm not sure how to just initiate the download. Nothing from rvest stands out since I'm not actually reading html. \n\nBasically, I'm looking for an R function like gotoURL('https://www.website.com/exportfullcsv) that will download the file just like it would if I entered the URL into my browser."

"jQuery plugin patterns: something more object-oriented?",
"I'm working on a jQuery plugin, following the pattern detailed in the Authoring guide. Basically:\n\n(function($) {\n // Private\n var doSomething = function($element, settings) { ... }\n\n var doSomethingElse = function($element, settings) { ... }\n\n // Public\n var methods = {\n init: function(options) { ... },\n show: function() { ... },\n hide: function() { ... },\n update: function(content) { ... }\n };\n\n $.fn.myPlugin = function(method) {\n if (methods[method]) {\n return methods[method].apply(this, Array.prototype.slice.call(arguments, 1));\n } else if (typeof method === 'object' || ! method) {\n return methods.init.apply(this, arguments);\n } else {\n $.error('Method ' + method + ' does not exist on jQuery.myPlugin');\n }\n };\n})(jQuery);\n\n\nHere's my dislike: I have to pass the same \"instance\" variables to all of the private functions. I'm still working on becoming a JS pro — so pardon my incorrect term usage — but if I were doing this same thing in Ruby or PHP, I'd create a class with all of these public and private members and methods, and each instance of the class would correspond to an $element. Then I could do something like this (in JS):\n\nvar firstElement = new MyPlugin($element, settings);\nfirstElement.doSomething();\n\n\nRather than passing $element and settings to doSomething(), it already has access to those via this.$element and this.settings.\n\nGet where I'm going with this? I'm looking for a more object-oriented approach, I guess. Now, I totally understand that JS doesn't have classes like Ruby or PHP. But between constructor functions, the module pattern, and regular object notation (like methods above), I'm not sure which is the best option for a jQuery plugin.\n\nCan someone help point me in the right direction? Maybe some examples of existing jQuery plugins that do this well? Thanks!"

"How do shared_ptr react when assigned a new variable?",

Will that mean the memory is freed, or do i have to watch out for something specific to prevent memory leaks?\n\nGreetings"

"char(32) data as primary key?",
"(NOT a duplicate of Char(4) as Primary key or whatsoever.)\n\nI am designing SQL Server tables for my project. I have two tables so far: Data and Ref.\n\nData structure:\n\nDataID SomeData SomeOtherData RefID\n\n\nRef structure:\n\nRefID UniqueData AlmostNeverUsedData\n\n\nUniqueData contains unique char(32) values and is involved in every single query on Data.\nAlmostNeverUsedData is needed on ~5% of these queries.\n\nI know using a non-data, auto-incrementing int field as the primary key is almost always better, especially regarding JOIN performances. But in this case, using UniqueData as Ref's primary key would allow me to avoid using a JOIN 95% of the time, since all of the data I need would already be on Data.\n\nDo the remaining 5% justify using an auto-incrementing int, increasing the queries' (and therefore the application logic's) complexity?"

"C++ Vector of Subclasses, using it to overload the istream/ostream",
"I'm looking to hold a Vector of Objects, of which will be Subclasses. \n\nI thought I would be able to do it by declaring a Vector of Pointers to the Baseclass (Such as vector<BaseClass*> db), and then declare it as a Subclass by doing something like db.pushback(new subclass) (My example in the link below is a touch different, but along the same lines);\n\n\nIs it possible to store Multiple subclasses in this sense Or will I need to define a new Vector for each SubClass? In the example given, there is only 1, but realistically in my program there is four.\nIf so, in my overloaded >> in SubClass1, would dynamic casting the type to a BaseClass work to call the friended overloaded >> in the BaseClass?\n\n\nhttp://ideone.com/QM5sRY\n\nEdit:\n\nSorry, I wasn't entirely clear in my second half of the question. I should have expanded.\n\nI have a program which needs to take an input, and distribute it throughout the respective Classes and Subclasses. It should take the input as Cin >> class;, in which case I have overloaded the >> operator. \n\nHowever, when I define the data as the Subclass (lines 34 to 39, and line 44), it appears to call it as a BaseClass, rather than a Subclass. It then calls the friend function defined in the Baseclass at line 10, rather than in than line 21. \n\nI'm not completely sure where I am going wrong.\n\nIdeally the output should be\n\nPrinting:Data\nX = 1\nY = 2"

"Ignoring exceptions handled by other assembly",
"I have an application for smoke testing several key services. I want these tests to be easily written and self discovering. To this end, I have created an attribute for each method in the style of [TestMethod] from MSTest. I have also created a object that will find all these methods and execute them within a try-catch. If the method throws an exception I report as a failure, otherwise as a success.\n\nThis is all very unit test familiar and that is the intention. So a test would look like...\n\n[MyTestAttribute]\npublic void TestingTimesAhead()\n{\n var d = DateTime.MaxValue.AddDays(1);\n}\n\n\nThe magic happens in the test object, this has an Action property and a Run method...\n\n public Action TestAction { get; private set; } \n\n public override ITestResult RunTest()\n {\n try\n {\n this.TestAction.Invoke();\n return new BaseTestResult() { Result = TestResultStatus.Success };\n }\n catch(Exception ex)\n {\n return new BaseTestResult() { Result = TestResultStatus.Failure, FailureException = ex};\n }\n }\n\n\nWhen ran in isolation the above test, being wrapped as the Action, will cause an exception and the test fails. Perfect.\n\nHowever, when I wrap the attributes and test running object up into a dll and reference from a new project, VS Debugger breaks for the exception.\nI am presented with an option in that dialog to toggle 'break when this exception type is user-unhandled'.\n\n\nI can suppress exceptions on a type by type basis, but that isn't going to work for reuse. Also, if I run the release build from the BIN output, the expected behaviour is there - it's just a really awkward development experience.\n\nIs it possible to manage this exception setting from my code instead? Or if anyone can suggest a way around the problem, I'm open to ideas."

"How can I sort an ArrayList>?",

"Class decorators in Python 2.5?",
"Is there a way I can make class decorators work on Google App Engine, which is limited to Python 2.5?\n\nOr let me rephrase that: is it possible to alter the behavior of Python's parser from the same process that it is already executing?

An alternative would be to run my code on Typhoon App Engine with a newer python, but I fear Google won't upgrade their Python version for a loooong time...\n\nEDIT:\n\nHow about creating a new-style import hook that would do string substitution on-the-fly and load the module from memory? That should be possible. I'll give it a try, if there's no implementation already out there.\n\nBut how can I parse Python 2.6+ code from Python 2.5? Is there a python-only parser?

I only have e.g. \"Login\", but I do not have \"BeginLogin\" and \"EndLogin\".\n\nSo I could call it sync (which works fine) but not async. \n\nHow could I get / create the begin- and end- methods?\n\nMany thanks!\n\nUpdate: Just to clarify: In Reference.cs of ASMXService of TodoASMX Sample App, there are these methods included e.g. for GetTodoItems:\n\npublic TodoItem[] GetTodoItems()\npublic System.IAsyncResult BeginGetTodoItems(System.AsyncCallback callback, object asyncState)\npublic TodoItem[] EndGetTodoItems(System.IAsyncResult asyncResult)\npublic void GetTodoItemsAsync()\npublic void GetTodoItemsAsync(object userState)\nprivate void OnGetTodoItemsCompleted(object arg)\n\n\nBut within my own ASMX Webserivce, only these methods are available e.g. for the default HelloWorld:\n\npublic string HelloWorld()\npublic void HelloWorldAsync()\npublic void HelloWorldAsync(object userState)\nprivate void OnHelloWorldOperationCompleted(object arg)\n\n\nSo you see, BeginHelloWorld and EndHelloWorld are missing...\n\nUpdate2: Problem is repeatable easily: Download the example provided by article https://developer.xamarin.com/guides/xamarin-forms/web-services/consuming/asmx/ at https://developer.xamarin.com/samples/xamarin-forms/WebServices/TodoASMX . It works fine. Now delete the webreference ASMXService from iOS Project and manually add it again. URL is http://todoasmxservice.azurewebsites.net/TodoService.asmx and type should be \".NET 2.0 Web Services\" because it's the ASMX sample, not the WCF sample. Now I get the following error messages because BEGIN and END Methods do not exist anymore:\n\n/TodoASMX/iOS/SoapService.cs(87,87): Error CS1061: Type TodoASMX.iOS.ASMXService.TodoService' does not contain a definition forBeginGetTodoItems' and no extension method BeginGetTodoItems' of typeTodoASMX.iOS.ASMXService.TodoService' could be found.

"How to support workday app with multiple docusign esignature accounts?",
"Workday supports the use of only 1 Docusign esignature Account Integration key to be configured in their system/tenant. However I need to understand from DocuSign community if there is a way to link multiple docusign integration key/account to the same Workday tenant using a custom integration. This way the documents from workday can be published into the respective docusign accounts for e signature (based on the geographic location)... Any ideas and experience on this ?"

"Is there a way to use a web image as cursor when hovering over a button? \n\nI tried something like this: \n\ntags$head(tags$style(HTML(\" .custom { cursor: url(https://c2.staticflickr.com/2/1907/31794847918_04f9e687e1_b.jpg), auto;\n} \")))\n\n\nwhich has no effect, and I can't find any other examples on the web how to manage this in R shiny. \n\nlibrary(shiny)\n\nui <- fluidPage( \n actionButton(inputId = 'messagebutton', label = 'click me')\n)\n\nserver <- function(input, output, session) {}\n\nshinyApp(ui = ui, server = server)"

"Is there a way to detect when bottom app tray is opened on iPad using JavaScript",
"I'm trying to figure out if its possible to use JavaScript to detect when a user triggers a gesture on iPad (and probably to a larger extent most iOS devices) that brings up certain UI elements. I need to perform certain checks should that happen but have no idea how to go about it. In particular, I'm trying to check for when a user brings up the app tray at the bottom of the iPad as seen in the picture below but it would be nice if there was a general solution to all such gestures like those shown here https://ipadpilotnews.com/2020/04/all-the-gestures-ipad-pilots-need-to-know-using-an-ipad-pro-without-a-home-button/ \nWould really appreciate if anyone can point in the right direction. I have tried creating event listeners for blur and focus as suggested in some other stack overflow question but those don't seem to work for what I'm trying to do. Thanks!"

"How to make ABC work with Boost.Python/C++ Classes?",
"I want abc.abstractmethod to work on the following class:\n\nfrom abc import ABC\nfrom my_cpp_module import my_class\n\nclass A(my_class, ABC):\n @abstractmethod\n def implement_me(self, arg):\n '''not implemented'''\n\nclass B(A):\n pass\n\nb = B() <--- should throw\nb.implement_me('hallo')\n\n\nBut this little example gives me\n\nTraceback (most recent call last):\n File \"./abc-test.py\", line 4, in <module>\n class A(my_class, ABC):\nTypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases\n\n\nFiddling a bit with type, classes and so on I get an implementation that runs without error:\n\nclass MyABC(type(my_class), ABCMeta): \n pass # type(my_class) == <class 'Boost.Python.class'>\n\nclass A(my_class, metaclass=MyABC):\n @abstractmethod\n def implement_me(self, arg):\n '''not implemented'''\n\n\n.. but in this case b = B() just works, too but (of course) I want it to produce the following error:\n\nFile \"./abc-test.py\", line 22, in <module>\n b = B()\nTypeError: Can't instantiate abstract class B with abstract methods implement_me\n\n\nIs there a way to make abstractmethod work together with Boost.Python classes like expected?"

"Is it possible to store messages in a socketio chat app",
"Let's say I made a complete UI of a chat app. We have a panel which contains all the recently contacted. We have react on the front-end and node, express on the backend. The real time data transfer chat is carried out using socketio.\nThe real question is how do I store all the messages that I have with each user. Let's say I chatted with user A for a while, closed the tab and moved to user B. Then the next day I moved back to the user A, I want all my previous chats with that user to be available to me.\nHow is that achievable?\nOne way I can wrap my head around is that I use mongoDB to create a chat room with two specific user and a id. Then I store that room on mongo with all the chats stored in an array.\nOn the client side, I check the db if a specific chat room exists. If it does, I send all the messages in to the client side, if not it create a new chat room.\nThis is by far the most sensible thing I've thought.\nAny guidance as to what other techniques I can use?\nMuch appreciated."

"Use Reactive Extensions to simulate Click on UIElement",
"In WPF, I want to be able to use the mouse events with reactive extensions to create an observable for a UIElement that works like a Click event. There's plenty of examples of using this to create drag/drop behavior, but I can't find anything for just a simple click.\n\nI'm anticipating it'll involve observables on MouseLeftButtonDown, MouseLeftButtonUp, MouseLeave, and MouseEnter. But I'm unsure what combination of Merge, SelectMany, TakeUntil, or TakeWhile I need to use. In trying to wrap it all up in an extension, here is what I have so far:\n\npublic static IDisposable GetClick(this UIElement item, Action clickAction)\n {\n var obs1 = Observable.FromEventPattern<MouseButtonEventHandler, MouseButtonEventArgs>(\n h => (s, e) => h(s, e),\n h => item.MouseLeftButtonDown += h,\n h => item.MouseLeftButtonDown -= h);\n\n var obs2 = Observable.FromEventPattern<MouseButtonEventHandler, MouseButtonEventArgs>(\n h => (s, e) => h(s, e),\n h => item.MouseLeftButtonUp += h,\n h => item.MouseLeftButtonUp -= h);\n\n var obs3 = Observable.FromEventPattern<MouseEventHandler, MouseEventArgs>(\n h => (s, e) => h(s, e),\n h => item.MouseLeave += h,\n h => item.MouseLeave -= h);\n\n var obs4 = Observable.FromEventPattern<MouseEventHandler, MouseEventArgs>(\n h => (s, e) => h(s, e),\n h => item.MouseEnter += h,\n h => item.MouseEnter -= h);\n\n var finalObs = ???\n\n return finalObs.Subscribe(x => clickAction.Invoke());\n\n\n}"
