Sharing a folder from Windows 10 host to Ubuntu in Virtual Box

1. First things first! Make sure that you have the latest VirtualBox Guest Additions installed. There are two ways to install it

    a. From Ubuntu Desktop Menu Option:
Start your VM and select "Devices > Insert Guest Additions CD image..."

    b. From command line with sudo permissions:
Execute "VBoxLinuxAdditions.run" file. In my case, it was under path - "/media/VBox_Gas_5.2.6".

    sudo /media/VBox_Gas_5.2.6/VBoxLinuxAdditions.run
2. Now share the folder between Windows 10 Host and Ubuntu Guest

    a. Create a directory in Windows on any location of your choice.
    b. In the VirtualBox, go to the settings of the Ubuntu Guest.
    c. Under the Shared Folder section, add the location of you folder created with full permission.
    d. Start the ubuntu guest and add your user to the vboxsf group:

     sudo usermod -aG vboxsf $(whoami)

    e. Logout the user and login again.

Now you can access your shared directory in /media/sf_(shared_folder_name).

Solving PyCharm bug: "Python helpers are not copied yet..."

I have been using PyCharm Professional to run and debug Python code from my Windows machine to a remote Linux device. There are some other tools available for the same purpose (e.g. Python Tool for Visual Studio 2017). But in my opinion, PyCharm Professional stands out among its counterparts as it comes with a "All Batteries Included" setup. Once you configure remote Python interpreter in PyCharm, then it works out of the box. However, today after upgrading to PyCharm Professional 2018.2.1, I could not run my Python script on remote device. The execution always failed with below error - "Error running 'hello': Python helpers are not copied yet to the remote host. Please wait until remote interpreter initialization finishes." To solve this issue, I had to remove the ".pycharm_helpers " folder from the remove device and then restart PyCharm so that the folder is re-created and files are copied again. Here are the steps with comma...

Customized Crosshair with OxyPlot charting library

I am using Oxyplot to draw heatmap for a WPF project and needed to draw a crosshair that moves according to user clicks. Since I couldn't find any good example or documentation on the topic, I made a small hack by using LineAnnotations and by over-riding Oxyplot mouse click event. Here is the sample code using WPF with MVVM pattern- MainWindow.xaml <Grid> <oxy:Plot x:Name="CrossHairPlot"> <oxy:Plot.Axes> <oxy:LinearAxis Key="MyXAxis" Position="Bottom" IsZoomEnabled="False"/> <oxy:LinearAxis Key="MyYAxis" Position="Left" IsZoomEnabled="False"/> <oxy:LinearColorAxis Key="...

Generating settings.SECRET_KEY in django

On some occasions, there might be a need to generate a random Secret key for your Django project. The easiest option could be starting a django shell and running the below command - from django.core.management. utils import get_random_secret_key get_random_secret_key () However, this may not be safe to use in a production environment. A better option is to use a defined a set of allowed characters including upper case letters and then use Django to generate a long key. Here is an example of it - a. Define a list of allowed characters lower_plus_numbers = ( list ( chr (o) for o in range ( 0x61 , 0x7B )) + list ( chr (o) for o in range ( 0x30 , 0x3A ))) punctuation = list ( '!@#$%^&*(-_=+)' ) upper_alpha = list ( chr (o) for o in range ( 0x41 , 0x5B )) b. Generate Secret Key from django.utils.crypto import get_random_string key_length = 60 get_random_string( key_length, allowed_chars=lower_plus_numbers + punctuation + upper_alpha, ) c...
