Attempt

After reading a large json file and capturing only the 'text' column, I would like to add a column to dataframe and set all rows to a specific value:

I'm a bit stooped on an issue I'm experiencing.

I have a python program which sends signals over a GPIO interface (Pi 4). The signals are dependant on a config.json

The layout of the json looks like the following:

So I am really confused on the logic here, I get the general Idea of taking my values in 1 by 1 and comparing them to the elements in the array. If the value is larger move on to the next element, if the value is smaller or equal to the element move over all the elements over 1 index and replace the original index with your value. My problem is I cant get that last part into code and I have been sitting here stooped for half an hour. Here is what I have gotten so far.

I have one script in which I have given following command -

su - postgres

psql

\c db1;

select * from employees;

But when I am running the script I am not able to go inside psql, its stooping after first command that is "su - postgres"

[root@quadoralnx ~]# ./ora.sh

Last login: Tue Aug 25 01:23:59 EDT 2020 on pts/11

-bash-4.2$

And when I am doing exit, it is giving following error -

-bash-4.2$ exit

logout

psql: error: could not connect to server: FATAL: role "root" does not exist

./ora.sh: line 3: c: command not found

./ora.sh: line 4: syntax error near unexpected token `from'

./ora.sh: line 4: `select * from employees;'

[root@quadoralnx ~]#

So here my need is that it should not stop in first step, and should run all the command in that script in single shot. Can someone please help me with this?

Thanks in advance!!

The goal is something like this: I start the app, MainActivity starts a drawing thread. This thread draws until some events inside it happens(in my case value i>155) Then this thread stops drawing (but it should not be deleted, and values should not be lost) and starts another activity (a usual xml - file activity) When I want I should be able to get to my drawing thread and resume communicating with it from the place I stooped

To solve the problem I have decided to use a SurfaceView thread and Canvas inside (It would be good to make it a class, not to write it inside MainActivity, because I'm going to insert there a lot of code). I managed to start a thread and to draw something on my screen, but I can't change the activity. The best attempt was to create a handler inside MainActivity and to send there a message from my thread. The thread works OK, but it just freezes and nothing happens when it is time to change the Activity. In the log tab I can see that the thread sends a message, but the MainActivity can't see and handle it.

What should I do? What is the right eay of solving the problem? Please, help a beginner).

MainActivity code:

As the title states I have a table in excel and I want to check if a row in that table contains certain values in it. For example: Table1 has

I realise this question has been asked previously, but I can't seem to get the code to work.

Here is my data:

I am learning c++, faced a problem with conversion operator. I am creating a complex class that can do basic operations on complex number.

I have two filters regexFilter and lastModified.
