Excel 2016 change logging feature?

I found some software that Git uses when editing Excel documents, and I thought that was a great idea, but then I remember that most Office Excel users do not really use Git.

Is similar functionality available for revisions and logging in the existing features of Excel 2016/2019? Or maybe integrated into SharePoint or Microsoft teams?

Computer Vision – Using Colors in Feature Detection

Is there a feature detector or extractor that uses color information?

Detectors like SURF and SIFT and many others work with grayscale. How do you think it can be transformed to create a grayscale image without losing color information but suitable for these algorithms?

In particular, I have to distinguish objects with similar shapes but different colors. And in general, colors provide more information about objects and allow them to be classified with better performance. That's why we have a color vision.

Google Sheets feature to display multiple different columns and allow editing

I am working with a table that is used by several people and contains more than 20 columns. Part of my work process is to search the rows and look at data from 3 or 4 different columns that are not next to each other. I just want to show those columns together and edit the data they contain. I thought filters or filter views might be the way to go, but apparently the data in the view can not be edited, and I could not find a way to combine multiple separate column ranges in filter views.

Do you have any suggestions other than that we should create our own custom application? ;]

Python – Change-due feature – Code Review Stack Exchange

I suggest you check the official Python style guide at PEP0008 https://www.python.org/dev/peps/pep-0008/ for information on writing a Pythonic style code.

def change_return(cost,paid):
  • Dokstrings: Python Docstring is the documentation string that appears as a string literal in the class, module, function, or method definition and is written as the first statement. Docstrings are accessible through the doc attribute for each Python object and can also be useful with the built-in help () function. You should add a docstring to your functions explaining what they do and what they return:

    def calculate_total_change(cost, paid):
        """Calculate change and return total"""
        # code
  • f strings PEP 498 introduces a new string formatting mechanism called the literal string interpolation, or more commonly F-string (due to the leading f-character before the string literal). … In Python source code, an f-string is a literal string prefixed with & # 39; f & # 39; containing expressions in curly braces. This facilitates the insertion of variables in strings.

    print(key + ': ' + str(value))

    can be written:

    print(f'{key}: {value}')
  • Blank lines: Too many blank lines in your function:

PEP008: Surround top-level function and class definitions with two blank lines.
Method definitions within a class are surrounded by a single blank line.
Additional blank lines can be used (economical) Separate groups of related functions. Blank lines can be omitted between a number of related one-liners (for example, a series of dummy implementations).
Use sparse rows in functions to specify logical sections.

  • A function should return A function usually returns something instead of printing.

            print('Insufficient funds')
        for key,value in change_dict.items():
            if value > 0:
                print(key + ': ' + str(value))

You could instead do the following:

return change_dict

Then use if __name__ == '__main__': Guard at the bottom of your script so that other modules can import your module without running the script as follows:

if __name__ == '__main__': 
    change = change_return(15, 20)
    if change:
        for unit, value in change.items():
            print(f'{value}: {unit}')
    if not change:
        print('Amount paid is exact.')

Here is a revised version of your code:

from fractions import Fraction

def calculate_total_change(cost, paid):
    cost: a float/int representing the total cost.
    paid: a float/int representing amount paid
    return: Total change (dictionary).
    units = (('Twenties', 20), ('Tens', 10), ('Fives', 5), ('Ones', 1), ('Quarters', Fraction(1 / 4)),
             ('Dimes', Fraction(1 / 10)), ('Nickels', Fraction(5 / 100)), ('Pennies', Fraction(1 / 100)))
    total_change = {unit(0): 0 for unit in units}
    if cost > paid:
        raise ValueError(f'Insufficient amount {paid} for cost {cost}.')
    if cost == paid:
        print('No change.')
        return 0
    if cost < paid:
        change = paid - cost
        if change:
            for unit in units:
                while change - unit(1) >= 0:
                    total_change(unit(0)) += 1
                    change -= unit(1)
    return total_change

if __name__ == '__main__':
    change = calculate_total_change(15, 22.5)
    if change:
        for unit, value in change.items():
            print(f'{unit}: {value}')
        print('Amount exact')

How do I override the feature protected by Core Layout Builder?

I am not sure which method is suitable for overwriting a protected core function. It's pretty easy with a hook, but a bit lost here. The goal is to exchange the warning for an error message, the hacking core works fine, but that's obviously not a long-term solution.

drupal-8.7.6 / core / modules / layout_builder / src / Element / LayoutBuilder.php

protected function prepareLayout(SectionStorageInterface $section_storage) {
// If the layout has pending changes, add a warning.
if ($this->layoutTempstoreRepository->has($section_storage)) {
  $this->messenger->addError($this->t('You have unsaved changes.'));
// If the layout is an override that has not yet been overridden, copy the
// sections from the corresponding default.
elseif ($section_storage instanceof OverridesSectionStorageInterface && !$section_storage->isOverridden()) {
  $sections = $section_storage->getDefaultSectionStorage()->getSections();
  foreach ($sections as $section) {

Software Protocol Definition / API Specification for the Ricoh Image Sync Feature

The Ricoh GR III camera can be used as a Wi-Fi hotspot (or as a Bluetooth connection). Connected to the camera, Android and iOS devices can download images from the camera or capture a live video stream and trigger the shutter remotely with Ricoh's "Image Sync" app.

I'm looking for a specification of the API or protocol description of how the app and the camera communicate with each other.

c ++ update feature does not work for vector objects

I've tried to update enemy sprites in my game by creating a vector of enemy objects and then using an update feature to animate the sprites. Although the enemy sprites appear on the screen, they are not updated to look like they're frozen.

I've gone through the update feature in the Enemy class and I'm sure there's nothing wrong with my code there. I wrote the following in my Source.cpp file:

#include "Enemy.h"

sf::RenderWindow window(sf::VideoMode(1920, 1080), "Zombie game", sf::Style::Default);


int main()

    sf::Clock clock;

    Enemy *enemy = new Enemy();
    enemy->init("Assets/graphics/zombieSpriteSheetWalk.png", 4, 1.0f, sf::Vector2f(200.0f, 200.0f), sf::Vector2i(100, 107));

    while (window.isOpen())
        sf::Event event;

        while (window.pollEvent(event))
            if (event.type == sf::Event::Closed || event.key.code == sf::Keyboard::Escape) window.close();

        sf::Time dt = clock.restart();

        for (int i = 0; i < enemies.size(); i++)
            Enemy *enemy = enemies(i);


        for (Enemy* enemy : enemies) window.draw(enemy->getSprite());


    return 0;

Is this a YouTube feature?

I see more and more of this stylization in pieces of music (audio only) on YouTube. Is it a feature where you simply upload the audio and set everything up according to the tags and the cover design? Or is it something the creators follow as the standard?

If it is a feature (which is likely), please let me know where I can access it.

How can I customize WordPress in sent emails using the wp_mail feature?

I create a contact form on the WordPress site.

The form works perfectly with the following code:

//validate email
if(!filter_var($email, FILTER_VALIDATE_EMAIL))
my_contact_form_generate_response("error", $email_invalid);
else //email is valid
//validate presence of name and message
if(empty($name) || empty($topic) || empty($message)){
my_contact_form_generate_response("error", $missing_content);
else //ready to go!
$sent = wp_mail($to, $subject, strip_tags($message), $headers);
if($sent) my_contact_form_generate_response("success", $message_sent); //message sent!
else my_contact_form_generate_response("error", $message_unsent); //message wasn't sent
else if ($_POST('submitted')) my_contact_form_generate_response("error", $missing_content);

However, this sends emails named "From" as "WordPress."

I'd like to customize "WordPress" with the sender's name, which I use the variable "$ name" to let me know who sends me e-mails without opening them.

Every help is appreciated.
