"Vue @click doesn't work on an anchor tag with href present",

This doesn't work, I have tried @click.prevent, @click.stop, @click.stop.prevent and none of these work.\n\nThe thing is that if I remove the href attribute, the @click method works great but an SEO requirement is to have href attributes on every link.\n\nAny help would be appreciated."

"Debugging parameter corruption in C++?",

I can print the values out at the top of the function, and they're correct, but not later on in the execution. Clearly something is corrupting the heap, but\nI'm at a loss of how I can try to pin down exactly what's overwriting that memory. Valgrind hasn't helped me out much.\n\nSample code by request:\n\nMy plugin looks something like this:\n\nvoid test_fileio::run(int argc, char* argv[]) {\n bool all_passed = true;\n\n // Prints out correctly.\n for (int ii=0; ii < argc; ii++) {\n printf(\"Arg[%i]: %s\\n\", ii, argv[ii]);\n }\n\n <bunch of tests snipped for brevity>\n\n // Prints out inccorrectly.\n for (int ii=0; ii < argc; ii++) {\n printf(\"Arg[%i]: %s\\n\", ii, argv[ii]);\n }\n}\n\n\nThis is linked into a system that exposes it to python so I can call these plugins as python functions. So I take a string parameter to my python function and break that out thusly:\n\nchar** translate_arguments(string args, int& argc) {\n int counter = 0;\n vector<char*> str_vec;\n\n // Copy argument string to get rid of const modifier\n char arg_str[MAX_ARG_LEN];\n strcpy(arg_str, args.c_str());\n\n // Tokenize the string, splitting on spaces\n char* token = strtok(arg_str, \" \");\n while (token) {\n counter++;\n str_vec.push_back(token);\n token = strtok(NULL, \" \");\n }\n\n // Allocate array\n char** to_return = new char*[counter];\n for (int ii=0; ii < counter; ii++)\n to_return[ii] = str_vec[ii];\n\n // Save arg count and return\n argc = counter;\n return to_return;\n}\n\n\nThe resulting argc and argv is then passed to the plugin mentioned above."

"Prevent thread blocking in Tomcat",

"Rails - dynamically generating deeply nested attributes in forms",
"I haven't found a solution for my particular problem, or don't understand it enough to know where to look.\n\nI have a nested form where I dynamically generate new objects as per Railscast 196/197. This works fine (in rails 3.0.9), except on a deeper level (3rd) with a mix of has_one and has_many. I am not sure if it's the necessary javascript modifications I don't understand, or associations, or initializing of nested attributes.\n\nFor simplicity, I translate my model so:\nThere is a tree that has_one trunk, and has_many apples. Each apple has_one core and has_many worms.\n\nWhen I create a new tree, my Create form automatically displays the fields for the trunk, and fields for one apple with one core and two worms (I like my fruit populated and social...).\n\nI can conditionally create an 'add' link for a trunk, just in case for some reason there isn't one.\n\nI can dynamically create an add link for a new apple. However, when I do that, it is not automatically initialised with one core and two worms. I take it that is because it is generated via the javascript/helper, and not in the tree controller's 'new' method, as is the case for the form itself.\n\nThat's not so much the problem for the worms, as an apple can have zero worms, so it makes sense to generally have an 'add worm' link there anyway. However, an apple should have one and only one core, so I don't want an add-link for that, it should just be there.\n\nIdeally, every \"add apple\" would initialise one core and two worms, though.\n\nI don't know how to adapt the javascript/helper to initialise the nested attributes of apple (core and worms) when i add an apple.\n\nI don't know, alternatively, how to initialise the apple object so that it has one core object initialised automatically.\n\nI don't know, failing all that, how to access the core property in the apple(s) property of the tree controller through the view, so that I could do something similar as I do for the trunk - that is, \"if for some reason trunk is not there, make a new one (or display an 'add' link to make a new one)\" in the _form partial.\n\n= if @tree.trunk.blank? \n - @tree.trunk= Trunk.new -# or 'display add button'\n= f.fields_for :trunk do |builder|\n = render 'shared/trunk_fields', :f => builder\n\n\n--> this, but for one more level. If I go to _apple_fields partial and try something like @tree.apple/s.core, I get errors, the same if I go one further into the _core_fields partial and try to make core available to check for blank?. I can't find the correct syntax for being able to access one of the many apple's cores. And it wouldn't really be the ideal solution anyway.\n\nAny pointers are greatly appreciated. I am guessing the solution is really simple and I am just too new to all this to see it..."

I have a solution that I created in windows forms for this back in VS2005, but now I am recreating the control using wpf, but I am not doing it in exactly the same way I had done it before.\n\nI have a listbox control that has the following DataTemplate:\n\n<DataTemplate>\n <Border CornerRadius=\"5\" BorderBrush=\"Black\" BorderThickness=\"1\">\n <StackPanel>\n <TextBlock x:Name=\"TaxonomyCode\" Margin=\"2\" FontWeight=\"Bold\"\n FontSize=\"12\">\n <TextBlock.Text>\n <MultiBinding StringFormat=\"{}{0}{1}{2}X\">\n <Binding Path=\"TaxonomyTypeID\" />\n <Binding Path=\"TaxonomyClassificationID\" />\n <Binding Path=\"TaxonomySpecializationID\" />\n </MultiBinding>\n </TextBlock.Text>\n </TextBlock>\n <TextBlock Margin=\"2\"\n Text=\"{Binding ElementName=TaxonomyCode,Path=Text,Converter={StaticResource TaxonomyCodeToDescriptionConverter}}\" />\n </StackPanel>\n </Border>\n</DataTemplate>\n\n\nBelow that I have 3 listboxes that list the actual Taxonomy Hierarchies using properties on my ViewModel...\n\n<ListBox \n Grid.Column=\"0\" Grid.Row=\"1\" \n ItemsSource=\"{Binding TaxonomyTypeLUT}\" \n DisplayMemberPath=\"IDDescription\" \n SelectedItem=\"{Binding Path=SelectedTaxonomyType}\" />\n<ListBox \n Grid.Column=\"1\" Grid.Row=\"1\"\n ItemsSource=\"{Binding SelectedTaxonomyType.TaxonomyClassifications}\"\n DisplayMemberPath=\"IDDescription\"\n SelectedItem=\"{Binding Path=SelectedTaxonomyClassification}\" />\n<ListBox \n Grid.Column=\"2\" Grid.Row=\"1\"\n ItemsSource=\"{Binding SelectedTaxonomyClassification.TaxonomySpecializations}\"\n DisplayMemberPath=\"IDDescription\"\n SelectedItem=\"{Binding SelectedTaxonomySpecializations}\" />\n\n\nThe actual datatbase binding is kindof complex as well. With multiple keys for each table in the hierarchy because each table can contain the same key that belongs to different parents... for example\n\ntaxonomy code : 207R00000X which breaks down to: 20 7R 00000 translates to: Allopathic,internal medicine,internal medicine\ntaxonomy code : 208M00000X which breaks down to: 20 8M 00000 translates to: allopathic, hospitalist, hospitalist\n\nEach of those break downs is the keyfield in its own table.\n\n\n\nHere is the design of my tables.\n\nI am trying to have my lower control change each child as a new selection is made. I have that working. Now though when I select the top list, I want the bottom lists to reflect the Taxonomy of the selected item. I can get that done too by binding One-Way. \n\nIf I don't bind oneway I get this ErrorMessage:\"The property 'TaxonomySpecializationID' is part of the object's key information and cannot be modified.\"\n\nIdeally what I want to be able to do, is change the taxonomy of the selected DoctorTaxonomy using the listboxes.

"Fast 2D drawing for generated image",
"I have an application, which generates image. Each frame is completely different and can not be accelerated by using of textures or sprites.\nI want to draw with high rate, but best I got with SDL is about 8 fps at 2560x1440 by using SDL's canvas.draw_point. I'd like to push it to 60 fps or more.\nI feel I'm doing something wrong. What is the proper approach to this problem?\nMy 'computations' are on separate threads, so I can dedicate a whole thread to a simple copy from a memory array to (whatever technology requires).\nI want to do it under X using Rust, so any X or cross-plaform library (including a pure C) is ok, but I feel that the problem is not within library, but in my 'per pixel' approach. How to do it right?"

"When do you multiply by the average Big O of nested loop?",
"When do we multiply the Big O of the outer loop by the average Big O of the inner loop?\n\nfor (int i = n; i > 0; i /= 2) {\n for (int j = 0; j < i; j++) {\n //statement\n }\n}\nAnswer: O(n)\n\n\nIn this question, the outer loop is O(log n). Since the inner loop executes some number of times based on 'i', the average Big O is taken. This results in a summation of n + n/2 + n/4 + ... = 2n which is then divided to get the average: O(2n / log n).\n\nHence O(log n) * O(2n / log n) = O(n).\n\nBut then why don't we need to take the average for this question?\n\nfor (i = 0; i < n; i++) {\n for (j = 0; j < i * i ; j++){\n\n }\n}\nAnswer: O(n^3)\n\n\nThe outer loop is O(n). The inner loop is O(n^2). But why?\n\nDoesn't the inner loop execute based on a value of 'i' in the outer loop? So why isn't the average taken like the question above? - resulting in something like O(n^2 / n) for the inner loop."
