Introduction

I often find myself ssh'ing into my servers and checking my systemd service logs with $ journalctl -f -u {name}.service. One day I got tired of this and wanted all of my important logs in once place (Amazon AWS Cloudwatch). To my dismay, there weren't any real good tutorials on how to do so. So, voilà.

Steps

Overall, it's a fairly simple process consisting of the following few steps.

1. Modify the service file

Open the service file with $ sudo vi /lib/systemd/system/{name}.service

Modify the [Service] section:

Send a quick SMS/text message .

aws sns publish --phone-number +12012022034 --message " This is bob. My phone's dead. I'll be home soon."

Things to note:

Start with +counrtycode

GraphQL Subscription with django-channels

Django channels are official way for implementing async messaging in Django.

The primary caveat when working with GraphQL subscription is that we can't serialize message before broadcasting it to Group of subscribers. Each subscriber might use different GraphQL query so we don't know how to serialize instance in advance.

C# For Python Programmers

Syntax and core concepts

Basic Syntax

Single-line comments are started with //. Multi-line comments are started with /* and ended with */.
C# uses braces ({ and }) instead of indentation to organize code into blocks. If a block is a single line, the braces can be omitted. For example,

	import axios from 'axios';
	import Config from './app.config';

	const instance = axios.create({
	baseURL: Config.apiPath,
	});

	* node vindecoder WBA3A5G59DNP26082
