  • Updated the Python Debugging page with more info on pdb.

  • Updated the Passive Filters page with more information on low-pass RC filters, including plots of the frequency response:

  • I created a public mbedded.ninja project on CircuitMaker at https://workspace.circuitmaker.com/Projects/Details/GeoffreyHunter/mbedded-ninja. I am going to trial out CircuitMaker as a tool for drawing schematic diagrams for this blog. In the past I have used Altium (not free), MultisimLive and InkScape (free but is a general vector graphics editor, not a dedicated electronics CAD program).

  • Added the Command-Line CSV Viewer page, which contains information on how to cleanly view CSV files from the Linux command-line.

  • Added a new page about the programming language Julia.
