Apple added a few non-standard interaction between SSH Agent and there own Keychain. This gave a great default of strong public-key cryptography with the convenience of not needing to enter a password all the time. But with macOS Sierra (10.12) the defaults changed[^defualts]. It took some time for people to figure out what was happening, but finally after 7 months, Bart Busschots explains how to reset the defaults and regain the old balance of security and convenience.
For more information on SSH, I recommend the Bart’s Taming the Terminal parts 29 through 33.
Many people set goals for the year. If you do this near January 1st it's called a New Years resolution. For the next 12 months, I am focusing on the word "compassion."
Vera Rubin, an amazing Astrophysicist who's research changed everything about galaxy formation and cosmology, died this week. If you study something larger than a collection of a few stars (like me), your research is impacted daily by her discoveries.
With a therapy dog at a hospital you quickly notice the patients that are there for rabies treatments. After recently being attached by an unknown animal, they don’t like the surprise of a dog in the hospital.
There are a few that are different. Recently one told the staff that they were looking forward to my visit. They petted Chance and had a nice visit. They had brought company with them, and they too enjoyed Chance. Then the nurses handed out some dog treat, as usual, and right on cue, Chance’s “lab-ervore” took over. I always expect it and I am always in control of him, but he starts darting around trying to find all the treats. He wound up getting a bit too close to this patient and I’m sure it triggered some flash backs.
After a few moments, and a lot of comforting, everything was OK. They even . . .
Having visited a hospital for around two years, Chance has met a number of patients who can’t speak for one reason or another. Chance does not miss a beat. He will say hello to anyone whether they say it back or not. There was one patient who loved dogs, but had a tube down their throat.
They were excited when we came in and sat up to looked at him. This was not a wise move for them. So they could lay down, I picked Chance up and put him in bed with them. They were so happy, you could see them smile. You could also see them trying to mouth the words “Good Boy.” I told them that Chance just loves pets and did not need anything more. I saw the relief when they realized they did not need to speak.
Recently we had a very sad visit; grief . . .
I have written and released my first utility! It takes a

This was the math problem that got me interested in problem solving as a career. Even though I choose a career in Astrophysics rather than Mathematics, this problem still holds a place in my heart.
