I am try to use the following Bootstrap code however it is only showing the first slide and not moving to the next one. Not sure whats going on :(...

If you are on Bootstrap 5 then the answer will be that you're using Bootstrap 3 syntax on one of the attributes.
The first line of my input contains two numbers: 𝑛 and 𝑑, denoting respectively the number of containers
(2 ≤ 𝑛 ≤ 20,000) and the number of deliveries (not more than
In the following 𝑑 lines there are pairs of numbers: 𝑤 and 𝑧, where 𝑤 is the number of wagons in the delivery
(no more than
20,000) and 𝑧 is the number of gravel in each wagon (no more than
The total number of wagons from all deliveries will not exceed
There will be no situation in any of the inputs where the container will contain more than
Wagons are emptied one at a time, evenly into two consecutive containers. These are the rules for determining which two adjacent containers are chosen (where
containers denotes a list of the
n current container sizes):
- Among all pairs
0 <= i < n - 1, choose the pair which minimizes
- If there is a tie, choose among the tied pairs, the pair which minimizes
max(containers[i], containers[i+1])(i.e. minimizes the second smallest element in the pair)
- If there is still a tie, choose the pair
(containers[i], containers[i+1])with minimum index
iamong the tied pairs.
The gravel is distributed equally into the pair. If there is an odd number of gravel in a wagon, the container with the smaller ID gains the surplus (1 pebble).
At first, all containers are empty.

You can solve this much more efficiently by using a min-heap (i.e. priority queue), such as the one provided in Python's standard library. The main purpose of a heap is for efficiently tracking the minimum element of a collection, removing that minimum, and adding new elements, which accurately reflects your problem.
Currently, the line:

Hey buddy I really don't know if this is the correct way of doing it, but it seems to work just fine. What I did was change the width to max width the make it from 60% to 18%. It looks good and like the lesson. then when you switch it to tablet or mobile, I had the @media function change it back to 60% so it didn't shrink all the way down and look weird. idk if I'm explaining it correctly but here's the code:

I am using multiprocessing (and pebble) to create one or more producer processes and one or more consumer processes. The producer adds items to a queue, the consumers pull from the queue and then call
task_done. My main function calls the queue's
join()function which should block until
all items have been processed (meaning that a task_done() call was received for every item that had been put() into the queue)
However, the join blocks forever even though
task_done has been called for each item put on the queue. See example below:

I'm trying to make two
List components: one of them is static and small, the second is incredibly large and dynamic. In the first
List I store food categories: Alcoholic products, Soups, Cereals, etc. In the second
List, the word is searched directly from the database - it can be anything: a dish or a category of dishes. Below is the code - it displays the start page. Initially, the first static and small
List is located on it, as well as the Search component (
Navigationview.seacrhable()). When you type a word into the search bar, the first
List disappears and the second one appears. At the moment, both sheets are loaded asynchronously. This is necessary because the second sheet is really big (thousands of rows). This is where my problem begins. Sometimes, when you type a word into the search bar, a copy of this sheet appears on top of it, as shown in the image. It only happens for a fraction of a second, but it's still noticeable. The problem is most likely due to asynchronous loading, before I added it, the
List was loading super slowly, but without such bugs.
My minimal reproducible example:
Main List, displaying the food categories available for selection....

id for the IDs, as mentioned in the comments, you can do some refactoring to get SwiftUI to not re-render as much of the view hierarchy and instead reuse components. For example, you have an
if condition and in each you have separate
ForEach, etc components. Instead, you could render the content of the
ForEach based on the state of the search:
I'm in the process of upgrading a small spring boot application from Java 8 to Java 11. This project uses the package
javax.smartcardio. I'm building it with maven.
pom.xml basically contains the following dependencies/plugins:
- spring-boot-starter-parent (2.5.6)
After upgrading all my dependencies and using OpenJDK11 the project compiles and runs fine (
mvn clean package). Especially the parts using the classes from
javax.smartcardio also work fine.
Intellij however, is highlighting all my imports of the package
javax.smartcardio. in red. When hovering over it, it tells me
Intellij - Package 'javax.smartcardio' is declared in module 'java.smartcardio', which is not in the module graph. Intellij suggests to add this module via compiler options with
--add-modules java.smartcardio. When doing so, Intellij stops highlighting the imports.
My question is now, why does Intellij highlight those imports, even though everything is compiling and running just fine nevertheless? What am I missing? Is it important to add that module when compiling? Maybe maven does something in that regard for me already? If so, which part should I lookout for?
I've read about using
module-info.java, but came to the conclusion that using it to resolve my problem would not be the best solution. See also Any plans for Java 9 Jigsaw (module) of Spring projects?

It is a known issue, please vote for IDEA-259485 Non-standard modules are not part of the class path in a non-modular module.
