The main advantage of this feature is that users can apply a message to their donations that will be seen on the stream. It becomes a way of paid communication with the streamer. You can use third-party tools or develop your own to implement the donation system. Chat Chatting is an ...
Emulators do not require any changes to cloud infrastructure (such as developer cloud accounts), so it’s easy to implement with existing testing patterns. Testing with emulators has these disadvantages: Emulators can be difficult to set up and replicate, especially when used in CI/CD pipelines...
To implement it in Python, you could enumerate() elements to keep track of the current element’s index:Python def find_index(elements, value): for index, element in enumerate(elements): if element == value: return index The function loops over a collection of elements in a predefined ...
For the "just posted" section the list of IDs can be used raw, or using the first pattern proposed in this blog post. Implement expires on items Another way to use sorted sets is to index stuff by time. We just use the unix time as score. This can be used in general to index ...
