it is giving this message
The unit bitcoind.service has entered the ‘failed’ state with result ‘exit-code’.
I have read that IV’s are used with block ciphers in case a sequence is repeated in a message and produces repeated sequences in the ciphertext.
I see IV’s being used in cases where the message is very short, though (e.g. 11 bytes in the example on the attr_encrypted Ruby gem README). Does the use of a unique IV also provide protection in this scenario? If so, how?
When I used WhatsApp desktop in Windows, I used
whatsapp://send?phone=[phone] to begin a new chat with an unregistered phone. I would like to do something similar in Linux.
I can open Whatsdesk with the link
whatsapp://app but when I use
whatsapp://send?phone=[phone], it doesn’t begin a new chat, this only opens the app
It’s not that queues are more scalable, its the fact that two services communicating through queue means the communication is asynchronous.
Asynchronous communication is far more scalable than synchronous communication, as it allows the writer (who enqueues messages into the queue) and the consumers (who dequeues the messages) to progress in their own rhythm.
Let’s say you have a REST API service which is being called from your client side and perform some long running operation task.
If the communication was synchronous (the API service doesnt return a HTTP status code before it finishes the task), on high volumes of traffic your API service may crash as it will be too loaded or it will not finishes his task on time, which will eventually result in HTTP timeouts.
If the communication is asynchronous, your API service will only queue messages that will be processed by some background worker, and it will be able to return HTTP response message relatively quickly.

I’m using Magento 2.4.1, and this is my message queue configuration in app/etc/env.php
'queue' => [ 'consumers_wait_for_messages' => 0 ], 'cron_consumers_runner' => [ 'cron_run' => true, 'max_messages' => 2, 'single_thread' => true, 'consumers-wait-for-messages' => 0, 'consumers' => [ 'product_action_attribute.update', 'product_action_attribute.website.update', 'exportProcessor' ] ]
I set the max_messages to
2 , I don’t know if this is enough or gonna cause any trouble later

i installed omnet++ then removed it , after that it’s always displaying message to me each time when i open the terminal, how can solve this problem ?
I’m wondering if it is possible to manually Ack or Reject message from the RabbitMQ within the Magento 2 consumer process? What is the default behavior?
Imagine a simple messenger app. Where to place the first message(s) in a chat? See examples below.
E.g. Slack, Facebook’s Messenger does it the A way. Snapchat, WhatsApp does it the B way.
I’d argue the B way is more correct due to F reading pattern, however, can someone shed me some light on this?
