Time Series Forecasting – a quick reference

Leave a Comment / Data Science, Essays / colin.catlin

*This is really not meant for an introduction, although there is some, but rather a reference of links and reminder for people who already know some of the basics (ie me!). I have been busy researching high-dimensional forecasting, and this is part of the result. A time series is any series of numbers that occur […]

Chickens One Month In

Leave a Comment / Farm / colin.catlin

I got interested in raising chickens back in 2009. I was already interested in beekeeping and self-sufficient farming. I was in England with my family. Of all things, happened to have the TV on in our hotel room and they had a feature story on Omlet’s then new Beehaus beehive. Looking it up later, I

Erosion: A Story of a Wabasha Valley

1 Comment / Essays, Farm, General Garden, Projects / colin.catlin

Once upon a time, there was no valley, no ravine, no house, and no driveway. Between 30,000 and 15,000 years ago, glaciers reached their maximum extent covering much of North America. As the glaciers melted, they formed a massive lake around 13,000 years ago called Lake Agassiz. Over roughly the next three thousand years this

Amtrak is Awesome for Medium Distance Travel

1 Comment / Travel / colin.catlin

Last Thursday I rode a train to Chicago from Winona. I returned this last Monday. The train was definitely the best method of travel for this journey. I could have driven to Chicago (5.5 hrs) or flown from Minneapolis/Rochester/LaCrosse (less than 1 hr in the air, lots more on the ground). The train took 6

Preparing the UCI Framelist

3 Comments / Cycling, Data Collection / colin.catlin

The UCI – the international cycling union, publishes a list of bike frames allowed in the World Tour – the series of races that comprise the premier event of professional road cycling. If there’s a premium mass market road bike, it’s on the list. And this list is a great way to analyze the development

New Bike Impressions: Ribble CGR SL

Leave a Comment / Cycling / colin.catlin

The Ribble CGR SL is a bike unfamiliar to most Americans, an English brand that has positioned themselves more on the value end of the market. ‘CGR’ stands for Cylocross, Gravel, and Road – its meant to do all three, and comes in steel, aluminum, and carbon, the last being what I have here. I

Farm Time Lapse Video

1 Comment / Farm, Photography and Drones / colin.catlin

For fun, I had the Raspberry Pi take pictures for a year with a PS3 Eye camera, and I then put them together into a little time lapse video. It’s really not that interesting, but easy enough to do: plugged in USB camera, cronjob to take the photo using the following script, in a .sh

Building a Rain Garden – and it actually works

Leave a Comment / Farm, General Garden / colin.catlin

I’ve always had an unusual interest in water control – particularly surface water flow control. I would like to build a dam across the ravine at some point to stop that big problem, but for now, a smaller problem. In the course of constructing the house and surrounding retaining walls at the farm, it accidentally

Polishing and Rebuilding a Titanium Bike

Leave a Comment / Projects / colin.catlin

My first road bike was a Motobecane Lechampion Titanium with Ultegra groupset that my dad liked so much that he bought a second one – that one with SRAM Force mechanical. My bike was given away a few years ago to a friend of a friend, a pastor who needed a decent bike for commuting

Kardemummabullar – Cardamom Rolls

Leave a Comment / Cooking, Travel / colin.catlin

Also available in cinnamon – kaneli, the cardamom roll is closely related to the cardamom bread we ate frequently as children in my family, which Kelly in particular loved. It’s a sweet bread with cardamom, nothing too complicated there. While related as well to the American cinnamon roll, the American versus the Swedish cinnamon bulle
