Formatting test

Here is a post with all kinds of crazy formatting so that I can test out my CSS.

Make sure the keyboard element Ctrl + Alt + Delete doesn’t mess up the spacing.

I’ve been using the following fish alias fzl (“fuzzy list”) to run fzf (“fuzzy find”) in the current directory with a bat preview. It’s just a couple of light tweaks to the examples listed in the fzf readme.

~/.config/fish/functions/fzl.fish:

function fzl
    # `bat` is aliased to `batcat` on Debian
    if type -q batcat
        set -f bat_command "batcat"
    else
        set -f bat_command "bat"
    end

    # Set the overall width of the `bat` preview to
    # 50% the width of the current terminal
    set -l bat_width $(math ceil $COLUMNS x 0.5)

    # My preferred `bat` options
    set -f bat_command \
        $bat_command \
        --style numbers \
        --color always \
        --italic-text always \
        --wrap auto \
        --terminal-width $bat_width

    fzf \
        --preview "$bat_command {}" \
        --preview-window right,$bat_width,nowrap
end

Example below.

Python example

https://github.com/maxkapur/cronjobs/blob/main/backup_nextcloud_contacts.py

def get_connection_parameters():
    parser = ArgumentParser(
        description="Create backups of Nextcloud calendar and contacts files"
    )
    parser.add_argument(
        "url", help="Nextcloud base URL (https://nextcloud.example.com)"
    )
    parser.add_argument("username", help="Nextcloud username (admin)")
    parser.add_argument(
        "keyfile", help="Path to file containing password (~/nextcloud_key)"
    )
    args = parser.parse_args()

    # Enforce HTTPS and allow some typical variants
    url = "https://" + args.url.rstrip("/").lstrip("http://").lstrip("https://")
    username = args.username

    with open(args.keyfile) as file:
        password = file.read()
        file.close()

    return url, username, password

def raise_an_error():
    x = 5
    if x > 4:
        raise ValueError(f"{x = } > 4")

class ClassExample:
    """A docstring.

    Has multiple lines.
    """

    def some_method(self, x: int) -> None:
        "Docstring."

        # Print it
        print(x)

Julia example

# Main purpose of creating this was to see "special" strings (symbol, regex) in
# action, but rouge doesn't parse them as anything special :(

if 5 < 6
    @assert match(r"\d", "hello2")
end

(string(:hello) == "hello" ? 5 : 6) |> sqrt

Math

In this post, we will show that functions of the form

f (X) \overset{ˉ}{1} - \prod i \in Ω ∖ X (1 - p i) \prod i \in X (1 - q i) f (X) = 1 - p r o d i i n O m e g a s e t m i n u s X (1 - p i) p r o d i i n X (1 - q i) f (X) \overset{ˉ}{1} - i \in Ω ∖ X \prod ​ (1 - p i ​) i \in X \prod ​ (1 - q i ​)

are submodular for pi,qi∈[0,1]p_i, q_i \in [0, 1]pi,qi∈[0,1] where each pi≤qi,p_i \leq q_i,pi≤qi, and examine an application of this small result that demonstrates its practical value.1
