Bujots - “boo-jots”: /buˈʒɒts/ A portmanteau of bullet journaling and Jots A web-based jot note app to create organized online notes Jot-Based Journals The goal of this project is to capture the joy and satisfaction of writing a beautiful journal entry and apply it to jot notes. Along with the ability to write daily notes organized in a timeline, users can freely customize their notes with stickers, adding personality and charm to each one....
Virtual Piano PianoTypes is a web-based piano that provides a full-range, customizable piano that is fast, visually sleek, and easy-to-use. While there are similar sites out there, PianoTypes tries to stand out by being a fully featured package and replicates most of the fundamental capabilities of a keyboard and more.

Not many code changes as of late but I’ve been more active on one of the packages I’m using to play sound, smplr. It’s such an amazing package for playing instrument sounds with an incredibly simple and powerful api. Kudos to danigb. A bunch of new changes were made recently that have added some awesome features as well as some bugs I found while using them. Note Scheduling Throughput The first change was a tweak to note scheduling that fixes an issue of the web audio getting overloaded and introducing lot’s of static....
Dot Product Find the interior angle between two vectors $$ A\cdot B = |A||B|cos\theta $$ $$ \theta = \arccos(\dfrac{A\cdot B}{|A||B|}) $$ $$ where\ A\cdot B = A_x \times A_y + B_x \times B_y $$ Cross Product Get perpendicular vector from two vectors Find area created by two vectors (for 2D, parallelogram area, for 3D, parallelepiped area) This is the magnitude of perpendicular vector Matrix Multiplication There is a formula for calculating the resultant matrix from a matrix multiplication....
Not too much to report. I had the realization that I can pause the scheduled notes by suspending the AudioContext since they depend on the context’s timer. It’d be pretty easy to add pause functionality. The only caveat is that if I pause the AudioContext, than all sound from the piano is also paused. Perhaps I could code in a notice to resume the timer given the user inputs a key press but I don’t want to resume the context on every key press....
A couple years ago I made a little extension for chrome to organize and sort tabs by url domains. It was really quick and crudely designed and since I wasn’t even a Chrome user, I didn’t think too much about improving it. Fast forward to now, I decided to do exactly that. Looking at old code Actually the code was mostly better than I expected, other than some variable naming and redundant lines, I didn’t see much need to rewrite it....
Today I spent some time working on getting the instructions dialogues up. I originally planned on creating a secondary overlay window that pops up given a trigger. Very similar to how to the toast notifications work but instead with a much larger area. The only problem with that is I wanted a clean way to inject custom html into the dialogue box depending on who triggers it. In the case of the toast notification I just pass it a string which is fine given it’s only suppose to be a sure notifier anyways....
I’m a bit more than late for a second devlog but I figured there’s no better thing to call this. I originally made this blog for the purposes of short and sweet devlogs but my recent posts have been bit larger than what I originally intended. I’m hoping with this log to bring that focus back down to just that. Since my previous post, I’ve done a lot of fine tuning of the UI and functionality of the site....
I recently finished a course in deep learning and wanted to took a look at a few ways I could apply my knowledge to. The idea the came to me was to create an ai music generation model and feed it into my old pianotypes app. Simple right! It’s all broken So I booted up my old, dusty, untouched, forgotten, delapidated, abused, ramshackled, repository, and lo and behold, I can’t get it to run....
I’ve been working on migrating my old PianoTypes project over from Vue to Svelte. So far the syntax has been much cleaner to use and has been an overall a great experience. My first and primary pain point thus far has been implementing a global reactive state for the piano. The Problem In Vue, it’s possible to add a reactive wrapper to any object. In my case, I had created a class containing all of the piano data and property methods so all I had to do was wrap this class in the wrapper and state is maintained across all instances of my piano class....
