Once in awhile a package hangs out at an old version even after a system upgrade or two. This can cause odd things like that software portion not working like it should. In my case, an old salbabix ios PPA that was long defunct as Ubuntu 18.04 and later have no problem just plugging in updated iOS devices.Continue reading “Removing old PPA from Ubuntu for stability and latest features”
What3words is an interesting alternative to sharing around long latitude/longitude numbers, instead share just a few words!

Last month we heard Google was getting sued again for collecting location data tied to user accounts. This is yet another reason it’s good to keep your Google account separate, away from your Google device if you have one. But last week Google announced that they will be changing this, auto deleting data after 18 months… but only for new Google accounts.Continue reading “Google sued over Android’s tracking, revises options.”

Recently a possible proof of the ABC Conjecture has been in the news. Although the proof of this is hundreds of pages long and not really a fun read for most people, this reminded me of the prime spiral, “Ulam spiral” which we explored years ago at a meetup.
The interesting thing about ABC Conjecture is that no matter what examples or counterexamples you find to the inequality, it does not prove or disprove the theory as to where there are only finitely many specific triples to solve the inequality.
Ulam’s spiral is also a look into prime numbers, but from a visual perspective. Nothing to “prove” here but to see an interesting pattern within numbers. It was supposedly thought of by Stanislaw Ulam during a meeting, doodling numbers, and it was later popularized by Martin Gardner’s writings. It is a great way to have some fun learning how to use Matplotlib to draw up some interesting charts, too:Continue reading “Possible ABC Proof Conjecture brings Primes into Prime time news again!”
