On first glance, this looks good, perhaps I will try to make a new site based on the tools.
Other articles like https://julienblanchard.com/posts/revisiting-my-journaling-habits.html, https://julienblanchard.com/posts/setting-up-a-9front-cpu-server-on-a-raspberry-pi-4.html look interesting too.

jq is a lightweight and flexible command-line JSON processor.

website2org.el downloads a website, transforms it into minimalist Orgmode, and presents the results as either a temporary Orgmode buffer or creates an .org file in a specified directory.
Might be useful for conversion of my few HTML pages to Orgmode.

Works only for places in Germany. See https://forecast.solar/ for a potential alternative.

jq is like sed for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text.

This section of the site offers RF engineers quick access to popular calculators and design aids. They are useful at design time and for training purposes, both of which stimulated their development and use over the years. Each tool is written in Javascript and the user can view the page source should they wish to examine the implementation.

I have tried to include references to the various books/papers that I have used in the development of each tool and although I have used them all at various times and believe them to be accurate, please use due diligence and further simulate where necessary.

Most of the tools come with sample values pre-entered into each input box to offer a degree of help. I apologise if this bothers you, but from the feedback I receive, it is generally preferred.

Please be sure to have read the "terms of use". The link is available at the bottom of every page.
