duplicate content – Disavowing fake websites

I may not be using the correct term here I know disavow refers to links to a website that you want to disassociate.

My question is about fake websites popping up pretending to be the real one, it is specific to restaurants where there are services provided by food delivery services such as in the UK; Just-eat and a few others. Just-eat is a food portal platform listing thousands of restaurants.

The scenario is, a restaurant has its own website `essex-restaurant.com and uses services from Just-eat and possibly others.

Because Just-eat wants users to go to their platform they make fake websites such as essex-takeaway.com and other platforms make similar such as essex-takeaway.co.uk.

They end up with 3 to 4 websites all competing against eachother. This results in the original restaurant website competing with these fake websites to rank.

Is there a way to tell search engines about fake websites, contacting the companies to remove it is not an option as it has been tried without success.

Any help would be appreciated.

hard drive – Backup fails because duplicate disks ‘Macintosh HD’?? How do I fix this?

I was having some issues (that I also didn’t understand, something about backup drive has changed name), that started happening with backups failing, so I decided to just reformat the external backup drive since I’m at a place where that is low risk. And now backups fail saying Two of the disks to be backed up have the same name saying I have two disks named Macintosh HD. This was working until a few weeks ago, and this a completely ordinary 13″ 2019 MBP.

Duplicate disks Macintosh HD

AFAICT I do not have two volumes named ‘Macintosh HD’ – here is disk utility,

Migrating from MariaDB to Mysql – Duplicate Constraint Name

I am attempting to migrate from MariaDB to MySQL by doing a mysqldump from MariaDB and then restoring it to MySQL (mysql:latest docker container).

I am getting the following error when importing into MySQL:

ERROR 3822 (HY000) at line 172: Duplicate check constraint name 'CONSTRAINT_1'.

If I look at the mysqldump file I can see why this is happening. All boolean columns in my database have a constraints that looks something like:

CONSTRAINT `CONSTRAINT_1` CHECK (`bool_col_1` in (0,1))
CONSTRAINT `CONSTRAINT_2` CHECK (`bool_col_2` in (0,1))
CONSTRAINT `CONSTRAINT_3` CHECK (`bool_col_3` in (0,1))

These constraints were not explicitly created by me but implicitly by Flask-SQLAlchemy (I think).

Notice how the constraint names are incremented starting with CONSTRAINT_1. Well the problem is that each table starts incrementing its constraint names starting with CONSTRAINT_1. Thus the error I am seeing gets thrown when trying to create the second table. According to the MySQL docs, duplicate constraint names are not allowed. Apparently MariaDB allows them.

Is there a way to rename these constraints systematically or an alternative way to migrate the data?

Note: This fiddle tests duplicate constraint names and executes without error on MySQL. However if I run the same commands on a fresh MySQL container, it fails with the duplicate constraint.

magento2 – Duplicate block content

I would like to duplicate the filters block content on layered category pages.
I’m using this code :

<referenceContainer name="category.product.list.additional">
    <action method="append">
        <argument name="block" xsi:type="string">catalog.leftnav</argument>
        <argument name="as" xsi:type="string">alias.name</argument>

but instead of duplicate the block it moves it to the new container and remove it from the left sidebar.

Thanks !

seo – Duplicate content, canonical url and json-ld Article

If I have a duplicate content, which URLs should I use in json-ld Article schema? To be precise, let’s say I want to publish an article from my blog.example.xyz on another site e.g. popular.example.com. When I publish the article on popular.example.com I go and update canonical URL on my blog.example.xyz, and og:url property (both should be same as implied here):

<!-- this is on blog.example.xyz -->
<link rel="canonical" href="https://popular.example.com/my-duplicate-article/">
<meta property="og:url" content="https://popular.example.com/my-duplicate-article/" />

I also use http://schema.org/Article to describe the Article entity, however, usually all URLs within it point to my own blog.example.xyz

<!-- this is on blog.example.xyz -->
<script type="application/ld+json">
    "@context": "http://schema.org",
    "@type": "Article",
    "author": {
      "name" : "Gitnik"
    "headline": "My Duplicate Article",
    "description" : "Uhm, how do I deal with Article entity in case of duplicate content?",
    "inLanguage" : "en",
    "wordCount":  600 ,
    "datePublished" : "2020-05-18T21:00:00",
    "dateModified" : "2020-05-18T21:00:00",
    "image" : "http://blog.example.xyz/img/logo.png",
    "mainEntityOfPage" : "http://blog.example.xyz/2020/05/my-duplicate-article/",
    "publisher" : {
      "@type": "Organization",
      "name" : "http://blog.example.xyz/",
      "logo" : {
          "@type" : "ImageObject",
          "url" : "http://blog.example.xyz/img/logo.png",
          "height" :  60 ,
          "width" :  60

but Google states that mainEntityOfPage should be same as canonical URL. Now, it’s easy to update mainEntityOfPage to the new url. But what about image url and organization? Can image url point to a location other than canonical url? And should I change Organization entity to the popular.example.com and change the url there also? How would it affect SEO if I left them unchanged? How would it affect SEO if I left mainEntityOfPage unchanged?

worksheet function – Excel – How to “combine” columns for a row, and create duplicate rows for the values in the combined columns?

I have a table like below:

Account# Code1 Code2 Code3    
123      A     B     C

And I would like to removed columns “Code2” and “Code3”, and create new rows like below:

Account# Code    
123      A    
123      B    
123      C

Unfortunately I’m not sure what this would be called, and every search for “converting columns to rows” turns up with transposing results. Is there some excel function that I can use instead of copying the rows and manually doing it?

Transit with Covid [duplicate]

My husband is coming to the United States for the first time on a CR1 visa. I want to ask, there’s a flight coming from pk to London. From London can he take a plane to the United States? The airport closes at 8:00 p.m. I think his flight is going to arrive around 6 pm, so he’d have to spend the night at the hotel and take a flight to the United States the next day at 11 AM. Does he need a transit visa or a visitor in transit visa? Where should we receive that from? Are they allowing people to transit because of COVID-19?
