Re-flashing the Librem Phone with Byzantium
If you just received a Librem 5 you probably have the latest software – including the new software that has a (mostly) working photos app, gps and a basic maps app! Development has continued on these devices but if you have one of the previous preorders you probably have been waiting on new updates and only getting a few standard package updates and no new apps 🙁
If you want to upgrade the phone in this case you need to re-flash it and wipe it with the newer version. Note this deletes everything and starts anew!
Their instructions here should be fine for some, but only if you have a very very new Ubuntu based system. If you have an older one such as Ubuntu 20.04 then you can get set up as shown below.

In Ben Sparks’ video he shows a very interesting trick. On a decimal angle calculator run:
sin(1/5555)
If your calculator has more than the standard Ubuntu calculator’s digits of accuracy you could add even more repeating 5’s. The answer is approximately PI with extra zeros…
0.000003142
Since today is Twosday (2-22-2022 in any date format), here is a similar Tuesday math trick for the Python console:
from math import sin
sin(22/700000.0)
It is also .0003142… or approximately Pi!

GTK Choice box with Glade and Python
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.

You may have noticed an issue with Youtube dislike count getting hidden, and it’s not just you… Youtube recently removed the dislike count, and hides it.

As you may have noticed, this past week saw major warnings for major Java applications or web services using Java and Log4j 2.x earlier than 2.15.0. You may wonder, how might this affect you and how can you tell if you are affected?

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.
