Let your voice be heard for Librem Phone/Pinephone Apps!

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!

Common Sense (and basic arithmetic) are not so common anymore

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.

Sum/product of consecutive numbers and other math shortcuts

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.

Purism price increase scheduled for end of June

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.

PyImageSearch Review

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.

Keeping a process running with a 3 line Bash script

While you are running a long running process, you may want to run it again if it stops or is watching some process that should be running all the time. At first look at this might seem best to…

  • Create some cron running a script that checks output of “ps aux | grep myprogram”, run it if it is not running.
  • Wrap some other Python script calling it and at the end wait and try running again.
  • Check in on the process and see what might be wrong. (Not great, if it is a process you want to be checking errors in you should be using Sentry anyway)
