The big picture: Fitted particle-filtering masks like N95s are up to 75 times more effective at preventing infection with COVID-19 than surgical masks, according to a study published recently in the Proceedings of the National Academy of Sciences.

Well researched article showing effectiveness of masks in the prevention of coronavirus spread. There is plenty of misinformation on this topic. Commonsense should be enough to tell us that masks work. Here’s some good science as well.

I have taken every precaution to prevent contracting one of the COVID variants. So far I have been very lucky. I am fully vaccinated and recently received a booster. I maintain social distance wherever possible. I’m tested on at least a bi-weekly basis. I wear an N95 mask. We had break-through cases in my family last year. All four of my children contracted the virus and I took care of them for two weeks. All of these measures played a role in my not contracting the virus.

The hot chocolate effect, also known as the allassonic effect, is a phenomenon of wave mechanics first documented in 1980 by Frank Crawford, where the pitch heard from tapping a cup of hot liquid rises after the addition of a soluble powder. It was first observed in the making of hot chocolate or instant coffee, but also occurs in other situations such as adding salt to supersaturated hot water or cold beer. Recent research has found many more substances which create the effect, even in initially non-supersaturated liquids.

Surprising phenomenon that I was unaware of. Via the excellent blog FYFD

The person that makes $20 per week and spends $19.96 will be happy. The person that makes $20 and spends $20.04 will be miserable.

I wish I could properly attribute that quote. I believe it was published in The New York Times around the turn of the 20th century. It was true then and it is true now. Personal finance really is that simple.

I just finished “The Alpinist” on Netflix. The movie follows Marc-André Leclerc, a Canadian rock climber and alpinist. The movie chronicles two years of his climbing. I am not a climber, but I have always had a deep love for the wilderness, the mountains, and the unexplainable feeling of summiting a peak. I am in awe of climbers.

Some climbing documentaries are exciting. They depict feats that hold me on the edge of my seat. “Free Solo” is such a movie. Others combine beautiful scenery with a rhythmic tension. “Touching the Void” comes to mind. “The Alpinist” is something different. It flirts with the typical tropes that are prevalent in climbing documentaries without becoming cliché. Questions of risk are asked but the filmaker seems happy to grant agency to Marc-André and other climbers. They are content to accept that certain people have developed different understandings of acceptable risk through training and experience, not because they are somehow crazy. The cinematography is gorgeous. Marc-André is genuinely lovable and extremely talented. It is a joy to watch him work a crack and watching him ice-climb is spellbinding.

Spoilers Ahead: read later if you are not familiar with Marc-André’s climbing and would like to see the movie first.

The director positions Marc-André’s summit of Torre Egger in Patagonia as the climatic climb of the movie but for me his first solo ascent on Mt. Robson’s Emperor Face is the highlight. The joy on Marc-André’s face when he states that “it was a very good day” perfectly captured the indescribable feeling of accomplishing something that you weren’t sure was possible. Marc-André’s life was cut tragically short. The filmmaker doesn’t shy away from his untimely death. The grief of his mother and girlfriend are heart-wrenching. There is no beautiful lesson to be learned in death. He lived a beautiful life. He was inspiring. He was loved. He died. Life goes on and it hurts like hell.

I appreciate that the film doesn’t strive for some higher meaning. In being true to the intensity of life that Marc-André lived and the intense emotions experienced by his friends and family when he died, the movie inspires emotion. I sat on the edge of my seat. I caught myself holding my breath with fear. I cried uncontrollably. I felt the pull of my backpack and the wilderness. “The Alpinist” is a great climbing documentary.

My birthday is coming up soon so it’s that time of the year when friends start reaching out and asking where they should fly to and how we’re going to celebrate.

After a good run in the post-vaccinated-and-boosted part of 2020 that felt relatively “normal”, including traveling almost 200k miles, I’m going back into a pretty locked-down state of things. Omicron has just been catching too many friends and loved ones, even with fairly careful measures and testing. So what’s happening on January 11th?

What I’m asking for my birthday is for people to blog!

I met Matt years ago at the University of Houston. I was done with school and was taking an elective course. I believe he was starting/passing through. It was one of those random encounters where you strike up a conversation with a stranger. Years later I heard him on a podcast and thought, “that’s interesting, I met that guy once.” I guess today is his birthday. He’s done a lot for the blogosphere and is still promoting it. I think it’s a good cause to promote. If you’ve always wanted to blog but haven’t “bit the bullet”, then try it today. There are more ways than ever to get started. Test the waters over at Micro.blog. It’s easy and has a great community. If you are a seasoned blogger then post something new today.

This is one of my more popular designs at PrusaPrinters. The stars are customizable via an OpenSCAD script. All stars print in place such that they can move relatively freely but remain captured within each larger star. I saw something similar on Twitter. It was mesmerizing.

Execupundit.com is a great follow. Add it to your favorite RSS reader if you haven’t already. Maybe there are new ways to follow, but I’m old-school. I love RSS.

Micheal recently posted a link to a great poem by Henry Wadsworth Longfellow, called “A Psalm of Life”. It is an excellent choice as a poem to guide us into and through the next year.

I posted a new make at PrusaPrinters. As a die-hard Green Bay Packers fan I wanted some homemade memorabilia of our current 3x MVP and future hall of fame quarterback. I drew the artwork on an iPad and then created an SVG file in Inkscape that was extruded using OpenSCAD for the final print.

I posted a new make over at PrusaPrinters. My kids wanted some toy coins to play with.
