There may be times you have a simple choice or listing in a GTK list box – for this example, in choosing a serial connection or other device. Glade is a good way to build an application window easily with an interface to build in to your app on Linux desktop, Ubuntu or Librem phone or other Linux based phones. I was able to use this to create a Winlink user interface for the previous tutorial to call up the Pat interface.

A previous posting showed how to set up Winlink through basic internet (Telnet). Internet/Wifi may or may not be available in any emergency, however, so it is important to be able to work Winlink over a VHF/UHF radio – which is the main benefit of WINLINK over e-mail, after all. To get this working you will need a radio, a TNC, and computer with the Pat or Winlink program. For my test I use a Yaesu FT-70 handheld, Mobilinkd TNC3, and Pat on a Linux computer.

A recent research project documented in Science shows a project they built to emulate the functionality of bird talon/grasping:

Treecard by Ecosia is a new debit card designed to reforest – and a card that is made of wood! Some previous app ratings suggested that this was “not real”, but it is in fact a real card – it has been delayed but the card production issues apparently were figured out, as they are shipping now.

Pi-start is a way to make a MMDVM (available from Newegg and other retailers) a DMR digital repeater node to talk with digital radio. If you have a Raspberry Pi, sd and reader, and a computer, you can set it up…

PineTime is one inexpensive yet very useful “smart watch”. If you want one that is open source, unlike those from Apple or Google, you will be glad to see this watch which is not only inexpensive but has software you can change (if you buy a dev kit version and know some wiring…)

As you may have noted if you have recently upgraded to Pinephone or Librem Phone, there are currently some missing spots as far as good and well built mobile apps for the platform. While this affords great opportunity for the first folks to build apps to profit from this growing segment, we also should encourage local app makers to fix their apps to work on Linux/Librem Phone!

If you have been thinking of buying the new Librem phone now may be the best time to do so! The price will be increasing $100 according to a recent posting on their blog. And what better way to celebrate independence day than a device independent of many of the major tech giants’ updates? You can even buy a Librem phone that is built in USA… at over double the cost, however.

Chances are you have seen a movie or book recently covering the topic of an EMP – an Electro-magnetic pulse from a faraway nuke that could cause outages and damage. While most of what you hear will either be dismissive of the possibility, or a horror story of years of electronic wasteland, the reality could be more in the middle and is something folks can prepare for, according to a US government publication linked in the documents section of the SHARES site.
The SHARES system is a HF long range ham radio service but there are several recommendations in the document that just about any civilian should be considering, not just radio maintainers and organizations:
