Happy New Year to all.

• Past year I published some Java Validation Classes for Keyboard input.

Is something very simple, but will help my student friends to validate Input from Keyboard without losing too many hours.

The Input Validation Classes I create in PHP for Privalia or in my PHP Catalonia Framework, are much, much, more powerful, allowing the validation of complete forms, rendering errors, etc… although they were created for Web, and not for Keyboard input.

• I also published a Bash script to count the lines of your programs.

It recursively goes to all the subdirectories looking for .py files, and then it counts the lines.

• I updated the price of my books to be the minimum allowed by LeanPub, to $5 USD, and created a bundle of two of them for $7 USD.

So people can benefit from this during the lock down.

• I’ve updated the Python Combat Guide book with a sample of using Paramiko Libraries for SSH, and increased the Object Oriented Programing and Unit Testing, sections. I also added some books to the Bibliography.
• I’ve read the postmortem initial analysis from Slack’s incident. It’s really interesting.

I cannot share it, but I guess that at some point they will publish it on their blog:

• I’ve been working on an article on How to install the Linux Kernel in Windows 10, with WSL as I got WslRegisterDistribution failed with error: 0x80070057.
  Update: The article has been published.

• As I’m giving more Python Classes I decided to write a book to teach to code in Python for non-programmers.
