Is It Whiskey Festival Time???

Is it time for the Ohio Craft Whiskey Festival ??

Previously I had build a Vestibulo-ocular Reflex Therapy App . I had put the details about building it in the page, but it got kind of long after I started adding features so I figured why have one article when you can have two, right?

The Form

The first thing we need is a form. Each of the inputs will call a javascript function to perform it’s function. The tempo can be input with a slider or a text box, and each will update the other. We also need a time limit and a font scale. If I knew a better way to calculate the actual size of the letter on the screen I could get around this, but alas I could not figure out a reliable way to do that. Maybe in the future!

VOR Physical therapy

I recently have had some vestibular issues related to how my brain and eyes communicate (badly). My issues are basically due to my gaze not locking correctly / some issues with peripheral vision. Once the source of the issues were identified I was given some exercises to do to help with the gaze stabilization.

The exercise basically is staring at a letter that is straight in front of me while turning my head side to side like in this video . Now I could just download a metronome app for my phone that’s going to steal my personal information, or I could have way more fun building a javascript app to do it. So I build a javascript app because as we all know I’m a big giant nerd.

Normally when folks calculate an asset’s weighted average life they use the formula $$ WAL = {{\sum_n{n \cdot Prin_n}} \over Par_0} $$ where $$ Par_n = \hbox{Par value at time n} \\[7pt] $$ and $$ Prin_n = \hbox{Principal payment at time n} \\[7pt] $$

In a previous blog post I had presented this formula $$ WAL = {\sum{Par_n} \over Par_0} \\ $$ without any context, other than to leave it to the reader to prove.

Advent Calendars

I bought a candy advent calendar for my wife and a whiskey advent calendar for me. I hope to write reviews for both every day, but I’ll give the over under at April for when I actually write it lol =P.

In previous years we got Advent calendars for the animals. Funny thing - dog Advent calendars are almost always treats, cat advent calendars are almost always toys, and horse Advent calendars… okay those don’t exist to my knowledge (or would be very expense). At the end of the day we were left with a bunch of cat toys that that the cats leave everywhere for the Roomba to eat

This year we got the Sugarfina Advent Calendar as well as the 2023 Flaviar Whiskey Advent Calendar . I was content to leave the candy to Barb and the Whiskey to me, but Barb decided she wants to try whiskey, so now I have to share. At least the calendar came with two glasses!

Well it’s the end of the year so it’s that time that I tell you to go check out my media wrap up for the year! Inspired by my friend Jen I started a media log, or at least keeping some kind of track of all the books I read, Jen catalogs all her media and I am not nearly that organized or ambitious. However, I did add a new entry this year for Unconventional Christmas Movies where I ramble on about Christmas horror movies in addition to my annual book writeup (that usually gets procrastinated until the end of the year lol)

Die Hard is a Christmas Movie

Building a Hénon map with javascript

I first found out about the Hénon map as an undergrad and have loved it ever since. Can I simulate it in javascript? Let’s find out!

The Hénon map is a dynamical system that exhibits chaotic behavior. It takes two parameters a and b. Depending on the values the map can exhibit periodic , chaotic or intermittent (switching back and forth between chaotic and stable orbits). It is described by the formula:

$$ \begin{aligned}
x_{n+1} &= 1 - ax_n^2+y_n\\ y_{n+1} &= bx_n \end{aligned}
$$

The Hénon map is basically taking the x-y plane and stretches, folds and squishes it like kneading bread. For some parameters it will tend toward a fixed point or set of points, but for others it exhibits chaotic dynamics - which means that no matter how accurately you describe the current position, it will be impossible to predict where it will be in the future (other than within the bounds of the attractor).

My Random Meditation Video Generator

I’ve been collecting a group of meditation videos on YouTube that I use to manage anxiety. This is mostly a place for me to come, press a button and get a random meditaiton video. So if you’d like a random meditation video to help with anxiety click the button below!

In 2022 I started listening to audio books on Audible and I read a lot of books. Inspired by my friend Jen I started a media log. Jen catalogs all her media and I am not nearly that ambitious and I actually wanted to start writing short reviews and that really doesn’t work with my work load/ADHD. So for the most part my media log is more like a running list of very short summaries of books I’ve read. I am certain that nobody really gives a shit but I’m not doing this for them anyway =)
