If you clone a repo to a windows system and want to run shell scripts like bash or zsh within the Windows Subsystem for Linux you might need to fix the end-of-line characters. This depends on if you preserve end-of-line characters based on what is in the repo or if you have your local repo auto manage that.
tr -d '\r' < a.txt > b.txt
Within most IDEs you can run "coverage" on your code which tells you how much of your unittests cover the code you have written. If you want to run this kind of coverage from the command line (terminal) for a Python project there are just a few simple steps to follow.
This can be tried directly by cloning this project and running the following.
Setting up a linter can help detect odd or non-typical coding practices. The following will describe how to setup PyCharm for basic linting with the PyCharm PyLint plugin.
This assumes you have a venv setup within your current project.
For pylint for your current project venv the following two commands should be run in your project root. The first will install pylint and the second will create an rc file which you can then adjust for your current project.
In some cases, you need to create a bunch of repeating code based on some data you intended on processing. In the following examples, I had all the field names listed in a powershell script but I just needed to translate it to C#.
I pasted the data in needed onto a linux box into a file called t.txt. This is the general format of the file where this is just a small piece of the 50 or so fields this script was displaying.
~/tmp % head t.txt
In cases where you want a layer around your PostgreSQL DB to minimize access, versus opening another port on a server for direct access (which you can restrict to an IP address or range), there is the option of accessing your DB through an SSH tunnel.
authorized_hosts setup to allow the tunnel to open automaticallypsql command from a client system's terminal.
In some cases, you may have an object the you are returning in an System.Web.Http.IHttpActionResult response where properties in the object you are returning have null values. To minimize the size of the data structure you are returning, a formatter can be specified which will let you supress null values.
Add using System.Net.Http.Formatting to the top of your code file.

If you have some Raspberry PI's running Ubuntu Server 20.04 connected to a flatpanel monitor, here are the steps to configure the screen resolution. In my monitor, the default Ubuntu is selecting is terrible looking and impossible to read. It is even worse at odd angles.
Check out this raspberry pi site for video resolutions. Based on my setup...
