Using most frequent letters used as root in TST

https://www.math.cornell.edu/~mec/2003-2004/cryptography/subs/frequencies.html
Still haven't worked on getting these links working. I really don't want to touch the blog html until I understand what I'm doing and to what
#the most frequent letters used in english in order: ETAOINSR
#average word length = 7.6
#using ETAOINSR as root, should result in a more balanced TST tree
#make that 'ointesra' so that E and T are in the middle.

Ok, I think if your making a search tree for strings, the best thing to do would be use these letters as a root in some way.

I have to test it, but I'll update when I get some data.
For the TSTree were using in class, It only compares the first letter of the root to decide equal, high and low.
So basically, if I'm just analyzing english text, I'd want my root to be 'E', as most frequently used english letter, I'd think that would distribute the highs and lows most evenly.

If its a whole string it's comparing to in set method, I'd think we'd want the etaoinsr more evenly spread, like maybe 'otsaerns':
Then again maybe I need to look what is most frequent 'first' letters of words.  What do most english words start with?

Anyhoo, I'll update when I fiddle with it. 
Earned myself some T.V. time today.  Woot woot!

JavaScript Ascii animation with while loops and console.log

I was working on figuring out while loops for an exercise in LearnJavaScriptTheHardWay  by Zed Shaw,  and I decided to do this: The red text console.logs were for debugging, and will take over the animation if the comments are removed. The bold red number is the point at which the loop stops.  My CPU didn't have too much trouble with that large number, but I'd recommend dialing it down if your CPU is slow. Also if your CPU is really fast, you'll have to change the pause to something much lower to see the animation better.  That too is in a loop, so the more that pause happens, the more loops your CPU is running.   Link: https://stackoverflow.com/questions/9006988/node-js-on-windows-how-to-clear-console To clear screen as described in link above, uncomment the bold purple comment I tried to comment the code to help learners see what I did,  any comments or suggestions, feel free to drop em in!        ...

playing with trigonometry sin in pygame

Image
Ok I am so far from understanding, so don't take this as any kind of math lesson. Also, every time I thought I knew what I was doing.... pygame would show me differently. Still a work in progress, but for now, something to play with. Update: SinWaveTime class added to produce that particular weaving effect Tinkering with the different sin wave variables: I wrote this piece separate from my 3D experiment to see how to manipulate the sin wave. While trying to use time as the factor to move my pygame draw circle on the x-axis, i got this crazy little doo-dad : I don't think it's drawing two circles at once, but if I figure out what the heck it's doing I'll let you know.  Or hey if you know, drop a comment.  I don't know if my comments are just not working, or no one wants to. So, here's some pygame code to play with the sin wave.  Alter the different variables to see it in action. picture of SinWave.move_with_time() see changes, SinWaveTime c...

JavaScript and a Matrix

Image
Screenshot of the code a 10 by 10 matrix Update 5/11/2021 I have successfully used the matrix to create a Snake game in Angular. See the live (Desktop only) game here: Firebase Deploy of Angular S N A K E Update 3/23/2021: I have changed the live version of the game to dynamically create the map for the minesweeper and this allowed for many open windows as to how I can upgrade and add onto the game. The easy version of the game allows people to learn and see how to form a strategy to defeat the original version of the game. There are sounds and options for game type and game size. Click on the options to turn the sound off if loud noises startle you as losing the games results in an explosion noise. Below is the link to the game, hosted on GitHub, and a GitHub link if you'd like to fork the code. Live Game: http...
