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.”

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

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.

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.

Eliminating Rust

“The story is, Australian sheep farmers noticed that steel things that sheep often rubbed against did not rust. Sheep’s wool is thick with lanolin, which is removed in processing the wool. Soap makers use it, it is also used in cosmetics.

One pound of anhydrous lanolin from eBay costs about $16. I mix it about 10:1 with light oil and apply with a brush or cloth. I also mix it with WD40 in a trigger spray. A pound goes a long way.

Since starting this about 10 years ago, rust is a thing of the past – except where I failed to apply this mixture. It has been 100% effective.”
