A-LINK | Code for A-LINK and A2-LINK | Machine Learning library

Given ONLY the playlist-id, can I create a link that starts playing at the first video?

Whenever I try to remove the video-id from a "watch"-url, it breaks, and linking to the "playlist"-endpoint doesn't start playing immediately.

Why does YouTube require a first video-id to be specified?

My reason for not including the video-id is that I want the player to start playing the first video even after the owner modifies the playlist and perhaps remove or replace the first video. I don't want the link to break just because of this.

To be clear this is what I meant:

Does not work (for me at least):

Doing the same with an embedded player apparently works fine, but not with a browser a-link.

I have this, but it returns the url of the web page. I want the "href" in a text string.

When creating singly linked lists, it is common to create a Node struct as follows:

In order to get some interesting data for NLP, I just started to do some basic web scraping in R. My goal is to gather product reviews from amazon, as much as I can. My first basic trials succeeded, but now I am running into an error.

As you can check from the url in my reprex, there are 3 pages of reviews for the product. If I scrape the first and second one, everything works fine. The third page contains a review from a foreign customer.

When I am trying to scrape page three I am getting an error indicating, that my tibble columns do not have compatible sizes. How can I explain this and how to avoid the error?

Also the error disappears, if I delete review_star and review_title from the scrape function.

I cannot seem to sort out this challenge. I want the div #project1 to show (visibility, opacity, display) when hover on #img1.

can't find the solution. would really appreciate some help.

Hi i have two html files Preloader.html (which is my preloader) index.html (which is my mainpage/homepage) now my problem is that when i load my site from preloader.html then it works perfectly like first it shows the preloader for 5.5 seconds then open the index.html .. but even in this case if i reload the site in index.html it doesn't load preloader.html

I am trying, using Selenium, to click the PDF icon (shown in screenshot 2) for each element (each of the containers shown in screenshot 1).

The problem is that the identifiers for the PDF icons are limited, so I am restricted to locating them with an XPath expression by class. At each iteration of the for elem in issues_numb: statement, the script clicks the first PDF icon it finds on the page, as it is the first element associated with the XPath fed to the script.

Is there a way to create a nested loop that for each instance of a class (article titles) clicks the instance of another class (PDF icons) that's associated to it? So for the first article, click the first PDF icon, etc...

I would like to make a portal in A-Frame. I followed this page on the official website. The portal is displayed, but I encountered 2 issues. Thank you in advance.

1. The title did not change even though I added a title tag in
2. I used VSCode + Live Server for development. When I click on the portal, I expected it to navigate to forest.html, but nothing happened.

My code is as below:
