heads-up | new heads-up notifications from Android Lollipop | Notification library

Just as a heads-up, I'm a total newbie in ocaml/functional programming.
I have a function, which is one of the recurrence relations for calculating Schröder numbers. It calls itself two times in the equation.
I want to count the number of times this function is called when an input is given (I know that for example, for n = 6 the function calls itself 25 times), preferably without using mutability.
This is the code I have right now. It evaluates to 76 function calls.

I have integrated Firebase Cloud Messaging to my Flutter mobile app with a plugin called flutter_local_notifications for showing heads-up notification in every state of the app. Everything is working fine until I created a Laravel project for sending notification to the specific device using device token.

I have integrated the Laravel project with Firebase Admin SDK and I follow the documentation for using Cloud Messaging. For now, the heads-up notification only showing in foreground state and not showing in background or terminated state.

Here is my testing laravel controller

So in my app when the time is up I want to launch an activity that notifies the user and then lets them dismiss the alarm.

I try to achieve it by scheduling an exact alarm and then launching a high priority notification with full-screen intent from my AlarmReceiver's onReceive(). The problem is that the activity doesn't launch when the screen is locked, all I receive is a heads-up notification that doesn't even turn the screen on, nor vibrates. It doesn't launch on my phone (Xiaomi X4 with Android 7.1.2) but it did on another phone I tried (Samsung Galaxy A5 with Android 6). I know that this is possible to achieve on my phone as I've observed that other apps like clock, phone, whatsapp and so on can do this.

I want to write a python program that can run packets through my local proxy server. But just as a heads-up, I know about requests library and I dont want to use the proxy option that comes with it. It only supports http/https. I want to be able to pass my port scans through proxies in python. Basically I'd like to make it so it runs as if I ran the script with "proxychains". Is there any way to do that?

I have a dataframe like:

Heads-up: This is a cross-language question.

I will demonstrate the problem by means of implementing a difference list. Here is the Scott encoded List, which provides the basic type. I use it with a dynamic type validator, hence I need a wrapper to associate the type List a with (simplified in the example below):

Heads-Up: I don't know if this is a duplicate, but all the questions that StackOverflow said to be similar are not mine.

Hi, I have a django model called Post (I am doing the usual 'blog' website, since I am still learning). I am creating a CreateView for it (django.views.generic) to create more posts.

My problem is that I want to pass in string as a context variable. This can be done with context_object_name or the function get_context_data. But, to create the form that CreateView automatically generates, it passes a context variable called form. Since I am passing my own context data, the CreateView's form context variable gets overwritten.

So, what I am asking is, what is the name of that form variable (if there is) that I can pass into the context data dictionary like {'string': my_string, form: createView_form_variable}.

CreateView:

I have large files that each store results from very long calculations. Here's an example of a file where there are results for five time steps; there are problems with the output at the third, fourth, and fifth time steps.

(Please note that I have been lazy and have used the same numbers to represent the results at each time step in my example. In reality, the numbers would be unique at each time step.)

The below given code you can see the magic of v-model, after checking / unchecking the checkboxes the array checkedNames will add/remove names automatically. We don't have to write anything to push/slice/filter names from the array, right?
