Back in the late 90s, when TI already ruled calculators in High Schools, I selected HP48 as my platform. It is a high-end engineering calculator with CAS capabilities, native units, stack based interface and programmable in RPL¹.

Recently I purchased a near mint HP48G and again have a physical calculator on my desk.

Today, I uninstalled my Blink security camera. It is a cloud connected device controlled by Amazon Corporation with full access to my recordings. I decided that uninstalling the camera is the most reliable mechanism to ensure my footage cannot be accessed (in the future) for privacy violating use cases (AI training, government overreach, etc).

Aircraft engines need to be protected from moisture to prevent internal corrosion. As their overhaul intervals often exceed 10 years and it is not uncommon for an engine to not operate for months at a time, protecting them from corrosion can significantly extend their operational life.

Saturday was a post-frontal weather day - very windy with active turbulence Sigmets. Fortunately, only areas west of Sacramento had high winds at the surface, while most other area airports had only moderate winds. Up above I saw 30mph winds, moderate turbulence and mountain wave with 1000fpm ups and downs downwind of ridges.

I try to open the year with a January 1st flight, but this year I couldn’t make it due to maintenance. Once the airplane returned into service, I took it up for some pattern practice across three local airports. It was a calm hazy day with an inversion. Did three-pointers and wheel touch-and-goes on a warm 20C January day :)
