Fix: starting the time plot on a specified time python

 To start a time plot at a specified time in Python, you can use libraries like Matplotlib for plotting. Here's a step-by-step guide on how to create a time plot that starts at a specific time:


1. **Install Matplotlib**:


   If you haven't already, you'll need to install the Matplotlib library. You can do this using pip:


   ```bash

   pip install matplotlib

   ```


2. **Import the Required Libraries**:


   In your Python script, import the necessary libraries:


   ```python

   import matplotlib.pyplot as plt

   import datetime

   ```


3. **Generate Your Data**:


   Create data points with corresponding times that you want to plot. For example, you might have time series data with timestamps.


   ```python

   # Example data with timestamps

   timestamps = [datetime.datetime(2023, 10, 27, 9, 0),

                datetime.datetime(2023, 10, 27, 10, 0),

                datetime.datetime(2023, 10, 27, 11, 0),

                # Add more timestamps here

                ]


   values = [10, 15, 12, 20, ...] # Your corresponding data values

   ```


4. **Create a Time Plot**:


   Create a time plot using Matplotlib. You can specify the start and end times on the x-axis using `plt.xlim()`.


   ```python

   plt.plot(timestamps, values, marker='o', linestyle='-')

   plt.xlabel("Time")

   plt.ylabel("Values")

   

   # Set the x-axis limits to start at a specific time and end at a specific time

   plt.xlim(datetime.datetime(2023, 10, 27, 9, 0), datetime.datetime(2023, 10, 27, 12, 0))

   

   plt.show()

   ```


   In the example above, `plt.xlim()` sets the x-axis limits to show data only between the specified start and end times.


5. **Customize the Plot**:


   You can further customize the plot by adding titles, legends, grid lines, and other styling options as needed.


Here's a complete example of how to create a time plot that starts at a specified time:


```python

import matplotlib.pyplot as plt

import datetime


timestamps = [datetime.datetime(2023, 10, 27, 9, 0),

              datetime.datetime(2023, 10, 27, 10, 0),

              datetime.datetime(2023, 10, 27, 11, 0),

              datetime.datetime(2023, 10, 27, 12, 0)]


values = [10, 15, 12, 20]


plt.plot(timestamps, values, marker='o', linestyle='-')

plt.xlabel("Time")

plt.ylabel("Values")


plt.xlim(datetime.datetime(2023, 10, 27, 9, 0), datetime.datetime(2023, 10, 27, 12, 0))


plt.title("Time Plot Starting at 9:00 AM")

plt.grid(True)


plt.show()

```


This example creates a time plot starting at 9:00 AM and ending at 12:00 PM. Adjust the data and timestamps according to your specific requirements.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
