I can punch through boards.
Today was the big board breaking for charity event at my dojang. I never really got the breaking boards thing until today. Oh man it is fun. It’s one thing to kick a pad and do forms but when you really let loose and put your fist or foot through a chunk of wood you get a total high off it. I’m probably sweating 90% testosterone at this point.
I’ll have to see if any of the pictures turned out.
A little more work on that map generator while dinner was cooking and now I have a hideous Voronoi tessellation of what was intended to be tectonic plates. I’m clearly going to have to rethink how I’m selecting the plate “centers” because I’m not getting the effect I want. Next up, Lloyd’s relaxation.
So after a couple weeks of futzing around with voronoi tessellations, locating implementations, rewriting chunks of those implementations to fit my needs, not being happy with the results, ripping it all out and starting over etc I decided I’d stick with what I Know and use a radial hex map. One cup of coffee, about[…]
It’s been a long week so I only have the basic WASD controller set up with a proper state machine. Now I can run around the featureless checkerboard plain with a few amenities like walking around a featureless checkerboard plain autorunning around a featureless checkerboard plain autowalking around a featureless checkerboard plain I’ll add jumping[…]
I spend a lot of time tinkering with various software projects, going at problems the wrong way, and generally making stupid decisions that a professional or more formally trained person would cringe to look at. Herein begins my cautionary tale as I learn painful lessons the hard way so you, dear reader, don’t have to.[…]
Coming away from the first class on the Bodhisattva Precepts at Buddha Eye Temple I have the following to roll around in my head for a while. The Bodhisattva Precepts used in the Soto Zen tradition encompass and expand on the ethics / sila encompassed in the Noble Eightfold Path. The sixteen Bodhisattva Precepts include[…]
I don’t know why I continue to use Windows. Every single god damned thing feels like pushing a giant rock up a hill. I’ll admit that the fact that I’ve been doing most of my work on Linux for the past twenty years inclines me to use the linux idiom for getting things done and[…]
HAL8999 7/100 I was sick yesterday but did spend some time looking over some “cheat sheets” that people had put together for various machine learning topics. Some were good, some were just stupid (I’m looking at you Machine Learning in Emoji). Also went through a very simply classifier based on the iris data set.

HAL8999 6/100 Watched the “Learn how to Learn” Google talk on youtube Updated the jupyter notebooks for handson-ml from github and read through the Ch2 notebook to address the CategoricalEncoder issue from yesterday Looked at a basic transformer Part of building a data pipeline is likely to include the creation of custom transformer classes to[…]
HAL8999 – 5/100 Today while going back through the Hands On Machine Learning book Ch2 I learned that the CategoricalEncoder referenced in the section on handling categorical attributes still isn’t in scikit-learn. I checked the reqirements.txt which shows scikit-learn=0.19.1. Checking my virtualenv, I should be good.
