Jamal Khashoggi's Last Piece

On October 2, Jamal Khashoggi, a dissident Saudi journalist residing in the United States, walked into a Saudi consulate in Istanbul to retrieve documents related to his upcoming wedding while his fiancée waited outside.

Fandible Numenera Podcast

Fandible is a roleplaying podcast with a cast of players playing a variety of games. I’ve been listening to their Numenera Longshot episodes and really enjoy it. I haven’t played Numenera, although I want to try. It is interesting to listen to a group tabletop roleplaying, and I also enjoy the storytelling.

More than ten years :gasp: since rewriting Geneagrapher (see a post about that here), I have published it to PyPI. Check out the Geneagrapher on PyPI!

My Geneagraph

It’s been a long time since I’ve written about Geneagrapher. In fact, I didn’t expect to look at the project again, but thanks to activity, I did a little clean-up work recently.

New Dwarf Planet: Get Ready for More

The discovery of 2015 TG387, a new dwarf planet nicknamed “The Goblin”, was announced today. According to a Carnegie Institution for Science press release, this object’s closest approach to the sun (perihelion) is about 65 AU; a little more than double Pluto’s perihelion. However, its orbit is highly elliptical, and its aphelion is about 35x further. The story here fits into a puzzle about a hypothetical ninth planet in the far outer solar system.

Hacktoberfest

In addition to the good feeling of contributing to a project and learning, some people that contribute at least five PRs will receive a t-shirt. Sounds like fun!

Changing Rear Brake Pads on Packster

Replacing the rear brake pads on the Packster for the first time was quite a challenge. I needed to get the rear wheel off the ground long enough to remove it and put it back on. To accomplish this, I parked the bike on a sidewalk staircase landing leading up to my house. The landing is a little larger than needed to have the front wheel and the center stand on the slab.
