@takbb’s KNIME Knowledge Archive

Below is my “bookmarks page” for “knowledge articles” that I have written and refer back to periodically. I hope these are of help to other KNIME users.

Would you like to buy me (or my wife) a coffee? ☕😎

I know that some people like to show their appreciation, and if you would like to do so, then please fee free to buy me (or my wife) a coffee at https://buymeacoffee.com/takbb. Whether you wish to do so is entirely a decision for you, and I am most grateful to those who choose to.

(If I can buy my wife an occasional coffee then I’ll perhaps be allowed to spend more time helping, so win-win, lol!)

If you do choose to buy one, please state whether the coffee is for me, or my long-suffering wife! thank you. BB

It us worth the effort, but when I went through the pain myself, I decided that some additional components might help.

  See the following articles that show:
