If you have tried at building an Android app recently you might notice that there is a new icon shown on newer Android Oreo, Android 10, Android 11 devices… it shows the Android antenna head instead of the normal icon. The odd thing is that the “design” area of the .xml file will display it but not let you actually design and draw in it like you can change layout xml. You can however use Inkscape or your favorite .svg editor and convert that file to this Android format:

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!

During the past year many have been able to give each other a good amount of grace and empathy and not judge them by their race, inability to wear a mask, or whether they go to the grocery store once a week or once a month to reduce their risk. Business owners have shown concern by giving special hours for the at risk or unvaccinated to come and shop early hours. And many have been using tools like microcovid.org to gauge the risk their household should budget. However not all has been as it should be.

If you are using Chrome 93, you may have noticed recently the “Your connection is always secure unless Chrome tells you otherwise” in the location bar. This raises an interesting question – should the system be telling you that any site that you visit is secure? Should we be trusting Chrome in this regard?

In the chapter The Long Tail of the Law, in Alex Bellos’ book The Grapes of Math, he shows some different statistical patterns that share the same properties:

If you have studied some of the old SAT questions at some point you may have gone through questions like –
4 consecutive numbers sum to 166. What is the product of the numbers? or…
3 consecutive even numbers sum to X. What is their product?
The way the tutors and the online tutorials show seems to always be to algebraically solve this – for example 4 consecutive numbers would solve x+x+1+x+2+x+3 = 166, collect terms and solve…
However there is another way that works for this and works for other similar problems.

If you have used Ham radio and are on Linux, you most likely have used the Winlink program Pat, an open source interface to use Winlink over internet (and some radios if you have that set up). The long awaited new release now includes the forms feature! and other improvements! If you haven’t set it up here is a quick review:

With a lot of misinformation about genes and the spreading of all manner of made up things on the internet it is interesting to read this pre-pandemic published book and some interesting history of viruses and gene technology.

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.

If you have been doing OpenCV or Python machine learning, you have most likely come across PyImageSearch. If you come across a sale for this service I would recommend trying it out if you are learning some machine learning. This past week they have run a free promo 7 day trial, which gave me an opportunity to browse these.
