short_url | ruby open source short url

I need to check if a given tweet contains or not alt_text.

I'm trying with API.get_status operation, which, according to its documentation contains a parameter to include alt_text:

include_ext_alt_text – If alt text has been added to any attached media entities, this parameter will return an ext_alt_text value in the top-level key for the media entity.

However, all I get is:

I have 5 links with tooltip hovers on each one except the last one. The reason the last one is different is because I'm using the tooltip to show the user their data was copied after the link was clicked. I would still like to have a hover for that link like the other ones that tells the user what the button does before they click it. I've included a sample below. I'd appreciate it if someone could help me figure out how to add the hover tool tip on the last link as well as having it still say "copied" after it was clicked.

I am learning to design systems. First use case is URL shortening service. I have read that we can store short_url,long_url pair in RDBMS. Since as per the requirement, we should be able to map a short_url to long_url (so that this can be sent to calling client) and also from long_url to short_url (so that existing mapped long_urls are not shortened again). My question is how these mappings/look-ups are efficiently done in RDBMS. Straightforward answer would be that index on short_url as well as index on long_url is maintained. I would like to explore its details like generally what indexing techniques in both cases are done in RDBMS.

I'm trying to create a url shortener and I'm creating the redirect part of it. I have a view that triggers when a user searches the short url that they generated.

I have a document links like this

I have two mongo documents of the structure

I can upload files from the PHP SDK, It is uploading and also getting the shared link back. But my issue is, how I can make and empty folder with password protected shared link. I am researching on it, but I could not find a good way to do it. Here is waht I researched.

In the code there is a promise.then that is attempted to be used to set a global variable originalUrl, however originalUrl is not being changed. Any help would be greatly appreciated.

I need to capture the return of the shorten method from the TinyUrl library. I'm trying to store this return in the shortUrl variable and then save it in the database as follows:
