Rad Power Bikes

Rad Power Bikes are priced at ~$1,500 and can replace an automobile in a variety of contexts. Bookmarking because I think the future will likely move to autonomous electric automobiles and some variety of electric bike, scooter, etc. for shorter distances. These may very well be where individual ownership moves, and the advantage of a bike is you’re less likely to get injured riding one than you would a scooter.

Inexpensive Landline/VoIP Service Replacement: The OBi202 Voice Adapter

Recently, I had a need for to have a plug-in, landline phone. A cell phone simply wouldn’t get the job done.

Our Internet provider was charging $50/month for VoIP, and even a VoIP specialist wanted $30/month. I wanted a less expensive VoIP option, and I thought there should be something that works with Google Voice. I found the OBi202 Voice adapter.

The OBi202 Voice adapter has two traditional telephone ports, two network ports, a USB and a port for power. This enables you to set-up a traditional telephone line and a separate line for a fax machine. Then, this plugs into the line between your router and the rest of your local network.

You pay a one-time fee for the device, between $65-100, depending on where you purchase and whether it is on sale. There’s a quick set-up process through their website. I had the whole thing up in running inside of 15 minutes. Recommended.

The tidyverse style guide

All style guides are fundamentally opinionated. Some decisions genuinely do make code easier to use (especially matching indenting to programming structure), but many decisions are arbitrary. The most important thing about a style guide is that it provides consistency, making code easier to write because you need to make fewer decisions.”

-Hadley Wickham, “The tidyverse style guide.” style.tidyverse.org

Probably the definitive guide for writing R code. See also Hadley Wickham’s Advanced R.


A note-taking tool for networked thought.As easy to use as a document. As powerful as a graph database. Roam helps you organize your research for the long haul.


I wanted to bookmark this for the future. I currently use org-mode in emacs for journaling and NextCloud Notes for a Keep replacement. But, this looks interesting.

The Best Lead Grade For Every Application

For thousands of years, people have used graphite to exercise creativity and bring ideas to life. Graphite is the key component of modern day pencil lead—in fact, lead is a misnomer as it’s actually made up of a mixture of graphite and clay. The formulation of this mixture determines its lead grade. The higher the proportion of graphite content relative to clay the lead has, the softer and darker the lead will be, and vice versa.

Lead grade is an important consideration for both the artist and writer. The hardness of a lead affects its strength, smoothness, smudge resistance, and pigmentation. Writers can fine tune the darkness of their lines by moving a step up or down in lead hardness, while an artist can employ the full range of lead grades to achieve different effects.

Probably more than you want to know on the topic of selecting a pencil.

Vertiwalk: An Alternative to Stairs

“Vertical Walking is a new system to move yourself between floors in a building. By exploiting the potential of the human body and materials, only a fraction of effort is required, compared to taking stairs. No external energy is needed.”


The intersection of how making things working for folks that are differently abled due to disease, age or some other issue and how that opens up new ways of looking at things for everyone else is really interesting. In the United States, your lifetime chance of dying from a fall is 1 in 114. The CDC states: “Every second of every day in the United States an older adult falls, making falls the number one cause of injuries and deaths from injury among older Americans, [for a total of 27,000 each year].

Changing the stair paradigm could make our residences much safer. It would also open up new architectural options.
