Remote phone development.

I remember when I started selfhosting my own instance of GitLab, which had simple code editor that allows you to edit code quickly inline. Then they integrated with fork of Visual Studio Code and allowed you to code in real repository directly in GL.

I was thinking of doing quick code changes to applications at this way, change some configuration of my API, quick fix of my mobile phone for home automation and etc.

sudo systemctl disable exim.service

Monitoring vs Observability

Thu, 20 Feb 2025 09:25:14 +0100

What is the difference between monitoring and observability?

Monitoring is process of collecting live events from your application, traces, debug messages, warnings and exceptions. The same process may involve sending those events to some storage or application that analyze or visualize those messages. I.e. in asp.net core applications monitoring of application involves calling a ILogger and sending those logs or critical exceptions to AppInsights. Monitoring may also involve activity of development team members to active watch those logged messages for any potential errors or problems that may impact availability of production environment.
