Andrey Zhukov's Tech Blog

This blog has been on hold since 2020, and every year I’m thinking of restarting it. This year is no exception.

The stopping factor was that it’s the technical blog. Yet, I write a lot during journaling and when preparing YouTube videos. I don’t know if I’ll be able to transform them into blog posts, but I’ll try.

Continue of previous task.

from azure.storage.blob import BlockBlobService, ContentSettings, PublicAccess
BlockBlobService(
                account_name=cluster_config["config"]["AZURE_STORAGE_ACCOUNT"],
                account_key=cluster_config["config"]["AZURE_STORAGE_KEY"],
            )
storage.create_container(container_name, public_access=PublicAccess.Blob)
        storage.create_blob_from_bytes(
            container_name, blob_name, content, content_settings=ContentSettings(content_type=content_type) 
block_blob_service.create_blob_from_stream(
                folder_name, filename, content, content_settings=ContentSettings(content_type=mimetype)
            )                       

from azure.storage.blob import ContainerClient, ContentSettings, PublicAccess
account_name = cluster_config["config"]["AZURE_STORAGE_ACCOUNT"]
        account_key = cluster_config["config"]["AZURE_STORAGE_KEY"]
        account_url = f"https://{account_name}.blob.core.windows.net"
        container_clients.append(
            ContainerClient(account_url=account_url, credential=account_key, container_name=container_name)
if not container_client.exists():
            container_client.create_container(public_access=PublicAccess.Blob)  # exception, or overwrite true
        container_client.get_blob_client(blob_name).upload_blob(
            content, content_settings=ContentSettings(content_type=content_type)            , overwrite=Tru

Recently I made an update for some legacy code and one of the tasks was to replace oauth2client. This library used to interact with OAuth2-protected resources related to Google API and deprecated since September 2018. The recomendation is to use google-auth and for OAuth 2 flow google-auth-oauthlib. The changes are simple.

Usually I have a lot of microservices and they communicate using REST API. For communication with frontend I still need REST, but between microservices gRPC looks more promising.

Some benefits of it:

• is built on HTTP2, using multiplexed streams - better connection management
• performance benefits because of Protobuf binary format
• code generation for a multilingual environment

Here is my first attempt to use gRPC in AioHTTP applications with some explanations.

If you have Redis integration in Datadog, there is an easy way to add monitoring for celery queues.

The more simple way is to add an endpoint to the service with celery. Here is an example of a low level way based on Message Protocol.

It’s my first mechanical keyboard and it’s about a year that I’m interesting to try it. I like my apple keyboard, but there are so many reviews for the mechanical ones, so finally I gave up and bought this IQUNIX A80.

I bought iPad 11" one year ago and I had a lot of doubts about it usefulness, it’s not one of the cheapest devices. If you are in the same position, maybe this post will help you.

If you, like me, suffer from celery banner in your logs, but still want to see useful information from it.

It’s almost a year that I did not post anything to this blog and here is a chart from Google Analytics.
