I'm reading code for a linux daemon and its main() function is structured like this:

I am very new to C# coding, or to coding at all, I am trying to create an API RESTFULL that when the user POST its email, it creates automatically a simples credit card number. I am at the very begging of the POST function.

// POST: api/Clientes

Goal:
Use state.firstName for displayModalContent in relation to viewing modal.

Problem:
When I opened a modal and then I want to close it, an error wil display "Cannot read property 'firstName' of null".

I don't know why this error occur and how do you solve it?

I have 3 table as mentioned below.

Table 1(users):

I have a pandas dataframe. I want to fill some of the cells with numpy array but I get the following ValueError.

I wil not fill with zero array in real life. This is the simplified example code to replicate the error

ValueError: could not broadcast input array from shape (10,) into shape (1,)

Sometime back when I was googling, I came across an HTML menu with a nice animation. I decided to use the menu in one of my projects.

On normal condition, the menu looks like

The original menu came with no sub-menus. I have added the sub-menu to meet my project need. On hover, the menu looks like:-

And finally, the dropdown menu looks like this:

As you can see that in the last image, there are some unnecessary yellow lines appearing in the sub-menus. I think it's happening because the child elements inheriting the style of their parent.

I have been trying to disable/override it by writing explicit class for the child element but no success at all. I have a workable knowledge of CSS. I want to write such CSS that it would remove the unwanted yellow lines as highlighted in the 3rd image.

I try to build my custom IoT device that will be controlled via Google Home device, and serve people with disabilities.

The device itself is Tiva C Launchpad, that I program from scratch, meaning I will have a full control on it.

In my vision, the user wil say something like: "Ok Google, press play button", and as a result, the Google Home device will send a direct command of press_play_button to the IoT device, preferably via the local network.

I found the Google Action SDK, alongside with the Local SDK extention, but if I understood correctly, I have to be in the app mode first ("OK Google, play {app_name}") before pronouncing the action I want, which is inconvenient.

Is there any way to achieve my requirement? If not, I may give up on the local network control, and use sort of a webhook to send HTTP request to my smart device, and in that case I wonder if MQTT will be more suitable.

Thanks.

I am trying to create a page that contains a list of cards. I designed the Header of the page but as a beginner, but I created it in my own way.

Problem is that when I am trying to display the card in the new Grid container its will not showing the desired result. Here the Image with the head I created

Here the I the problem picture when I try to put Grid container

My Style and Code :

I have a pandas DataFrame containing rows of nodes that I ultimately would like to connect and turn into a graph like object. For this, I first thought of converting this DataFrame to something that resembles an adjacency list, to later on easily create a graph from this. I have the following:
