QUESTION
I am looking to find a pair of numbers with a GCD (Greatest Common Denominator) of 1, that the first N terms of the sequence X0, X1, ... XN are all composite.
For my code, for some reason, it gets stuck when i == 15, j == 878, and k == 78. It gets stuck when running is_prime() on the two last items in the list.
...ANSWER
Answered 2021-Jun-15 at 22:27The problem is that your is_prime function is to slow, instead of checking if every number is a prime inside of your for loop. Why not generate a list of primes, lets say the first 1 million, store them in a list. Then too check if your number is prime, just check if it is inside of the list.
QUESTION
I need to get token to connect to API. Tried with python this:
...ANSWER
Answered 2021-Jun-12 at 17:16First note that a token must be obtained from the server ! A token is required to make some API calls due to security concerns. There are usually at least two types of tokens:
- Access token: You use it to make API calls (as in the Authorization header above). But this token usually expires after a short period of time.
- Refresh token: Use this token to refresh the access token after it has expired.
You should use requests-oauthlib in addition with requests.
https://pypi.org/project/requests-oauthlib/
But first, read the available token acquisition workflows:
https://requests-oauthlib.readthedocs.io/en/latest/oauth2_workflow.html#available-workflows
and choose the right workflow that suits your purposes. (The most frequently used is Web App workflow)
Then, implement the workflow in your code to obtain the token. Once a valid token is obtained you can use it to make various API calls.
As a side note: be sure to refresh token if required.
QUESTION
I have a Spring Boot app with a Kafka Listener implementing the BatchAcknowledgingMessageListener interface. When I receive what should be a single message from the topic, it's actually one message for each line in the original message, and I can't cast the message to a ConsumerRecord.
The code producing the record looks like this:
...ANSWER
Answered 2021-Jun-15 at 17:48You are missing the listener type configuration so the default conversion service sees you want a list and splits the string by commas.

QUESTION
There are so many questions around that deal with finding the most common value in an array, but all of them return the "first" element in case of a tie. I need the highest value from the list of tied elements, imagine something like this:
...ANSWER
Answered 2021-Jun-15 at 14:30Not sure how you'd go about solving this with Numpy, as there is no way to alter the tie-breaking logic of argmax, but you can do it with collections.Counter easily:
QUESTION
As you might know, most common video container files are like zip archives that contain several other files: the actual video, several audio files for different languages and several text files for subtitles and captions. If these tracks are included in the video file, that's called packaged afaik.
Now, while HTML offers the element to reference additional files, are browsers capable of choosing among different packaged tracks and display different subtitles?
How is browser support?
...ANSWER
Answered 2021-Jun-15 at 14:13No, they can't, even though the HTML standard encourages browser vendors to implement such controls.
The standard allows several audio and video tracks per media resource, and exposes them via JavaScript:
A media resource can have multiple embedded audio and video tracks. For example, in addition to the primary video and audio tracks, a media resource could have foreign-language dubbed dialogues, director's commentaries, audio descriptions, alternative angles, or sign-language overlays.
4.8.12.10 Media resources with multiple media tracks
Additionally, the standard encourages controls for different audio tracks and captions.
If the [control] attribute is present, […] the user agent should expose a user interface to the user. This user interface should include features to […] change the display of closed captions or embedded sign-language tracks, select different audio tracks or turn on audio descriptions […]

I have a class SocialAuth, which holds some common properties of the AuthModel class. Now I want to dynamically update the instance of AuthModel based on the object of SocialAuth class.
I'm looping over the .toJson() of SocialAuth and trying to update the property of _authModel (Instance of AuthModel) dynamically.
ERROR IS - The operator '[]=' isn't defined for the type 'AuthModel'.
SocialAuth Class
...ANSWER
Answered 2021-Jun-15 at 10:31You get the error, as the operator []= isn't defined for the type AuthModel as the AuthModel class has not defined the [] operator.
You will need to define the operator [] in the AuthModel class,
