Better things to do this Oct 31st

This has been a challenging year for many of us, and while it may be tempting to go visit neighborhood houses for parties or candy, the extra sugar and staying out in the cold could possibly be a setback from healthy progress in recent weeks. Some say sugar worsens immune function. Instead you might consider activities including:

  1. Reading, study
  2. Watch some interesting Makerfaire videos, as most areas didn’t get a Makerfair this year 🙁
  3. Build something on the computer and present at a hackathon – there’s a Tmobile hackathon, a Here Maps hackathon, Post COVID Hackathon, hack-or-treat going on.

New England Repeaters added to Hearham.live Repeater Listing and Repeater-START

The Repeater-START app now includes repeaters imported from the New England Repeater Directory. This makes the app and repeater listing much more useful to those in Massachusetts, Connecticut, Vermont, Rhode Island, New Hampshire and Maine! This expands the repeater-START app and any other applications needing an offline, fairly complete listing of amateur radio repeaters worldwide.

Building a mobile app for Linux, part 4: GPS/mobile tracking

Another important part of many mobile apps is location tracking – there is, fortunately, there is a built in api for most Linux systems called Geoclue that should work… There is even a Python-geoclue package, but after some digging I found that this package does not work in Python3. In fact it’s hard to find examples or documentation, if you look at the files of the package you can see there are some basic docs:

Building an amateur radio app for Linux, part 2

In the previous post I showed how to add some icons to an application showing OpenStreetMap, with Python and GTK+. Next, I’ll show how to make a listing of nearest repeaters to selected area. The listing of all repeaters is in the local array, and since there is a .distance(lat,lon) that gives the distance to a point, the list of repeaters can be sorted by closest to a certain point that is selected – in the on_button_release function. The Python Gtk guide shows an example that can be integrated in to the code to add a Listbox. The listbox should be “self.listbox” so various functions can access and change it. Below the other widget/control code, this must be added, within a gtkScrollWindow or adding many items will expand the window awkwardly:
