I am just beginning with C++ and I am trying to write a cricket scorer. Right now I read in a team list for the home and away team from two text files. That works well. I have created classes for Over, Ball. Basically an Over is a vector of balls (usually six legal balls). So usually one particular bowler bowls one over and...

I'm trying to scroll through an ipywidgets.interact plot using my arrow keys in a Jupyter notebook. However, even when I click on the slider (highlighting it) and then press the left/right arrow key, I navigate up and down between code cells. Is there any way to scroll through plots without having to use the mouse?

in a Django 5.2 application I discovered LoginRequiredMiddleware. It's a great system. However, I have some problems with the media. When a url has the @login_not_required() decorator, it's impossible to display uploaded images. in the console, when the page is loaded, django considers this as a next_url.

I'm trying to figure out on what to do as my recyclerview seems to be not working. I'm still fairly new to mobile development so I'm not exactly sure I'm gonna do. There was no error/warning messages in the logs regarding recyclerview and it still was able to run the build however my only issue is the said recyclerview not being visible. At first...

I want to replace a? with b? where ? is a character, not a wildcard. Here is what I tried: echo "a?c" | sed 's/a\?/b?/' I expect b?c, but it returns b??c. I also tried two backslashes between a and ?, it doesn't work either.

I'm creating a .bacpac file of a database on a server and then restoring that .bacpac file onto another server. When I do that the values for user_type_id for custom user types within sys.types is inconsistent between the two instances. Everything still works correctly because tables that use a specific custom type still have the same type, just its user_type_id is different. For example,...

I need to clean few xml files from not needed elements, came up with this wild card replacement for nothing to get rid of not needed <EmbeddedImage>, but I'm missing how to store each change in the loop, looks like it overwrites it each time. Thought that Python will keep it, but it's not the case. Do I need to create some additional logic...

I'd like to create a generator factory, i.e. a generator that yields generators, in python using a "generator expression" (generator equivalent of list comprehension). Here's an example: import itertools as it gen_factory=((pow(b,a) for a in it.count(1)) for b in it.count(10,10)) In my mind this should give the following output: ((10,100,1000,...), (20,400,8000,...), (30,900,27000,...), ...) However, the following shows that the internal generators are getting reset:...

I am trying to plot results from a beta-diversity anaylsis done in the adespatial package in a simplex/ternary plot. Every plot has the data going in a straight line. I have encountered several papers that are able to display the results in the desired plot but I am having problems doing it in my own code. I feel like the cbind step is where...

I got a ListBox and I like to show a list of Data. Using the breakpoint I see that the list (CsvLines) has many entries. But the ListBox is empty. Why stays the ListBox empty? Here my code: <Grid Grid.Row="1" Background="Yellow"> <ListBox ItemsSource="{Binding CsvLines}" Background="Pink"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Margin="4"> <TextBlock Text="{Binding ID}" Margin="5" /> <TextBlock Text="{Binding Date}" Margin="5" /> <TextBlock Text="{Binding Time}" Margin="5"...

Why does variable shadowing not work in the Chrome Dev tool console? But it does in Node.js: const a = 1 { const a = 2 } This throws a: VM1195:1 Uncaught SyntaxError: Identifier 'a' has already been declared

I have the following problem. In my application I use 'black' theme from ttkthemes, with some additional changes. I also uses dialogs for getting values. I also have created my own dialog with ttk.Combobox widget to allow user to choose a value instead of typing it. The standard dialog uses default style (as it's tk based, not ttk) which is totally OK for me....

I'm working on a project to compare different filament detection algorithms that take an astronomical grayscale image as input and give a binary skeleton of the filaments detected as output. For your reference, I'm attaching an image from a related paper: Image for reference about the usage of filament identification algorithms In the image, left shows an input image and right shows a skeleton...

Let's say I have two classes B, C with pure virtual f,g functions respectively. I want to create a child class A which conditionally inherits B or C. I know how to inherit from a different base class based on template parameter (let's say non-type bool template parameter): template<bool test> class A : public std::conditional<test, B, C>::type { ... } How to conditionally override...
