## Android: cover photo duplication problem in the Facebook iOS mobile application

When I try to update / change my cover photos through the Facebook mobile application (iOS), a copy is created as a cover photo without retaining likes and comments. These are cover photos previously set in the cover photo album on my Facebook account. I am not making a new charge from the device. Such duplication does not occur when I test it on the Facebook application on Android, the Facebook mobile site and Facebook on the PC.

Do you also have the same problem in iOS? Is this a kind of error or failure? What could be the reason for this? Thank you.

## \$ 40 per favicon, default facebook and cover photo

https://domainpager.com is the website and I need a default photo + cover photo (https://www.facebook.com/domainpager).

I also need a favicon.

Some guide is that the cover photo must have the features listed on the home page and something like "never miss a chance with premium domain welcome pages", we have 3 types of forms … buy it now, make an offer and contact us. Users also cannot have forms on the page and should only use the Domain Pager as the placeholder homepage / countdown timer. The concept is that many domains have private privacy who.is and people have no way of contacting the domain owner. With this service, domain owners can maintain their privacy while allowing people to contact them for inquiries and opportunities.

## algorithms: points to cover with circles and points to avoid

The points are in the 2d Euclidean space. Given a set of n points, A and a set of m points, B, what is the minimum number of circles so that the set of circles covers all points in A and no point in B is covered by a circle?

circles can have an arbitrary radius

Any ideas on the difficulty of this problem? Any ideas on exact non-trivial algorithms?

## mg metric geometry: cut a given triangle into 2 mutually congruent convex pieces that together cover most of the triangle

Two flat regions are congruent if one can be perfectly matched with the other by translation, rotation or reflection (flipping).

The problem: Given a triangular region T, how will we divide it into 2 mutually congruent convex pieces that together cover the highest fraction of the area of ​​T? Let's call such partition the best congruent partition of T.

And what is the specific shape of triangle T so that the largest fraction of its area is left over ("wasted") under its best congruent partition of 2?

Note: One can generalize from T and ask for a general convex region C that & # 39; wasted & # 39; the largest fraction of its area when it is given its best congruent partition 2.

An attempt on this question was published here: https: //arxiv.org/pdf/1012.3106.pdf.
Note that the document analyzes only partitions in convex parts. I don't know any conclusive results on this question.

## Why do you duplicate my cover photo without retaining your likes and comments on Facebook's mobile?

I tried to change my cover photo using the Facebook mobile application and I wanted to revert one of my old cover photos I used years ago. I checked the cover photos that later appear on the profile picture (cover photo album on my Facebook profile). I clicked on the photo I wanted to use, however, it was updated as a new upload without retaining its likes and comments.

Then, I logged into my Facebook account on my PC, deleted the duplicate and did the same process again. This time, my previously used cover photo, along with likes and comments, was successfully updated without having any duplicates.

What could be the reason for this problem? Is this something common, a kind of mistake? My mobile operating system is iOS. I could not see any complaints / examples on the Internet regarding this issue.

What I can do? I see that my DB tables are in ASCII and my collation is utf8mb4_general_ci

RESOLVED by adding the AUTO_INCREMENT option in some tables. I installed a new site and compared both databases to see where I need to add this option.

## Is there a mistake on Facebook's mobile to update the cover photos?

I tried to change my cover photo using Facebook's mobile and I wanted to have one of my old cover photos that I used years ago. I checked the cover photos that later appear on the profile picture. I clicked on the photo I wanted to use, however, it was updated as a new upload without saving your likes and comments on the cover. In addition to the previous one that I wanted to update as a cover photo, there was a duplicate on the cover.

Then, I logged into my Facebook account on my PC and deleted the duplicate cover photo and did the same process again. This time, my previous cover photo with the old likes and comments was updated successfully keeping their likes and comments without having any duplicates.

What is the reason for this problem? Could my mobile application understand my previous photo as a new photo due to the fact that my profile was first uploaded to a PC that was not mobile years ago? I could not see any complaints / similar examples on the Internet regarding this issue.
