magento2 – Overrides the mini cart icon less in custom design

I created a custom theme that overrides a luma. I've placed the following less in _extend.less, but there is no effect. Vendor default web css source_extend.less

.icons-font-list {
    list-style: none;
    padding: 0;
    li {
        float: left;
        width: 25%;
        margin-bottom: 35px;
        text-align: center;
        > span {
            .lib-icon-font('', @_icon-font-size: 34px);
            &:before {
                content: attr(data-icon);
                margin: 0 auto;
                display: block;
                border-style: solid;
            }
        }
    }

}}

Original frontend CSS:

.minicart-wrapper .action.showcart:before {
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    font-size: 22px;
    line-height: 28px;
    color: #757575;
    content: 'e611';
    font-family: 'luma-icons';
    margin: 0;
    vertical-align: top;
    display: inline-block;
    font-weight: normal;
    overflow: hidden;
    speak: none;
    text-align: center;
}

macos – Red dot that appears in the software update icon but has already been updated

I just updated my Macbook to the latest version of Mac OS: Catalina 10.15.4.

However, I have noticed that there is a red dot on the software update icon in the system settings. After clicking, however, it is indicated that the symbol is already up to date.

So I want to know why it is here and how to get rid of the red dot?

Thank you in advance!

Filter – Remove the add to cart icon

I'm trying to remove a button that appears when you hover over the images in a Woocommerce shop. (See the pictures below)
Icon that is displayed
The product is a variable product.

If I can't do this, I also tried formatting it to be a normal product view button using the code below. However, I have problems with how I can format it otherwise.
Any help much appreciated.

// Change button text on WooCommerce Shop pages
add_filter( 'woocommerce_product_add_to_cart_text', 'woocustomizer_edit_shop_button_text' );

function woocustomizer_edit_shop_button_text() {
    global $product;
    $product_type = $product->get_type(); // Get the Product Type

    // Change text depending on Product type
    switch ( $product_type ) {
        case "variable":
            return __( '£', 'woocommerce' );
            break;
        case "grouped":
            return __( 'View All Products', 'woocommerce' );
            break;
        case "external":
            // Button label is added when editing the product
            return esc_html( $product->get_button_text() );
            break;
        default:
            return __( 'Buy Now', 'woocommerce' );
    }
}

Network – How do I get my network icon back?

System specifications: –
Dell Vostro 14
OS – Linux 04/18
Use NVIDIA 340.107 binary driver from nvidia-340

It all started with not being able to see my home WiFi on my list of visible networks.

1. I decided that something was wrong with my network adapter (as people say Dell drivers are not compatible with Linux) and went for a "tip code that I didn't fully understand on my shell"!
Wrote commands like
"Sudo Ishw-businfo" to probably find and repair my network drivers.

  1. The command that made my network icon itself disappear in the top right is: –
    Sudo apt-get purge -y hostpad && sudo apt-get purge -y network management && sudo restart

  2. After that, it completely disappeared. Besides my Bluetooth icon, I couldn't find a way to connect my laptop to an internet connection. Also tried a LAN cable.

If anyone can suggest an action to reverse the command I foolishly entered in step 2, I would be very grateful.

Since I see no way out
I am thinking of backing up Linux on my PC and reinstalling it.
