E-Rick's questions

I use linux-mint I am trying to install docker. I have followed the steps:

sudo apt-get remove docker docker-engine docker.io containerd runc
 sudo apt-get update
 sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

But at the moment of executing: sudo apt-get update I get the error that I have put above.

It has almost no information so I guess the solution is very obvious but not for me. I am trying to install docker.
I've just cut and pasted, I understand where I could have gone wrong.

How to create a hash like this done in Node.js but in php.

const bdHash = criptoHub.sha256(stringToHash, KEY);

I think the error I have is that the week variable is no longer a jquery element. How could I transform it again so that it would admit the methods of the jquery elements?

How can I find the elements that have a certain class within the result of the elements that contain a certain class?

$('body').on('click', '.dia', function(ev) {
  $(this).addClass('active');
});


$('input').on('click', function(ev) {
  let diasElegidos = [];
  let diasDeCadaSesion = $('.sema');
  diasDeCadaSesion.each(idexWeek => {
    week = diasDeCadaSesion[idexWeek];
    console.log({
      idexWeek
    });
    let dias = week.find('.active');
    dias.each(dia => {
      diasElegidos.push(dia.data('day'));
    })
    //console.log({diasElegidos});
  });
});

.dia {
  display: inline;
}

.active {
  color: red;
}

The solution to the problem does not have to be in jquery.

I have a form with some input disabled (why? -> I explain it below) and I want the values ​​to be sent in the submint.

Why they are disabled: Because their values ​​are calculated based on the rest of the input and I have not set them as readonly because I do not want the focus to pass through them when I press the tab key.

I am using jQuery and javascript.

I have been given an example of an api call with this date format: endDate=2022-04-24T11%3A09%3A32 And I don't know what the A and % mean. Neither is this 100% of what minutes, seconds, etc. correspond to... Not even if I have to reconstruct them with one or two figures, in 12 or 14 format... Someone is familiar with this format.

I'm looking around how to schedule a task for the last day of the month. But I find very twisted solutions like this:

[code language="bash"]59 23 28-31 * * [ "$(date +%d -d tomorrow)" = "01" ] && execute_this[/code]

There has to be a more readable solution!!!

I already have emmet installed VS Code Twig Language 2but apparently the shortcuts don't work. I have tried with: 'div>*2'by doing a test and it does not work.

I have tried "div.html>.twig"as this page says:

https://community.c9.io/t/emmet-not-working-in-html-twig-templates/23087 and hit tab twice and nothing...

Let's say for example that I want 'system monitor' to fire at a certain time. I would go to crontab and.... What name do I put? It has happened to me more than once that I have needed to know the command that triggered an application and I have had to dive a lot on the internet to find out. I am looking for a more general solution, somewhere in the OS I will be able to see the command that launches an application that I have installed in my OS!! Nope?

I'm doing a course on a shared computer and I'm saving my work on github.

But of course... the repository is linked to the github account and they could do malicious pushes in the repository.

How would I unlink the git credentials of the computer and my project from my account every time I finish the class?

A kind of git logout.

I put this pseudocode that I know doesn't work to explain what I want to do:

resultado = 0 
fecha1 = 2000,1,1 2:21 
fecha2 = 2001,1,1 4:44 
resultado = fecha1-getAño(); 
resultado = fecha2-gerHora() 
dump(resultado) // 2011,1,1 T4:44

From what I'm seeing, I have to decompose the dates into year, month, days, hour, minute, second, and then recompose them into one...

Isn't there another more direct way? There has to be an easier way!!

I am trying to create a php snippet in visual stydio code. I want that snippet to already include a variable, but when I fire the snippet it removes the dollar sign from the variables:

code snippet:

    "Print to console": {
        "prefix": "rick",
        "body": [
            "$rick = $1;",
            "dump($rick);",
        ],
        "description": "hace un dump"
    }

code resulting from firing the snippet:

rick = ;
dump(rick);

It doesn't work for me to use '\' as an escape character:

"Print to console": {
        "prefix": "rick",
        "body": [
            "\$rick = $1;",
            "dump(\$rick);",
        ],
        "description": "hace un dump"
    }

it gives me the following error:

Invalid escape character in string.json(261)
