Random picture maker with noise continued

Previously I posted about a script I wrote to generate random colorful pictures.

Picture maker and noise function

  It allows you to select an area using a box to guide the randomness of the color.  This allows you to somewhat control what the picture looks like.



I also talked about how I thought I could use Perlin noise to make the pictures look less like confetti and a little more like a painting.

I have moved forward with those ideas a little bit.  I made a copy of my other page.  I also found a nice implementation of Perlin and Simplex noise in js.

Currently I have the script starting with a bunch of points doing a random walk around the canvas.  Then you can click on a point and it will start a new drawing point using the color you clicked on.  After you pick some of your own points it starts to look kind of cool.  I'm not sure I like the way it starts out though, buy I'll keep working on that.





You can see in the picture how the page starts out.  Also I have clicked a few times in the green area in the lower middle of the picture near the box that you see.  You can see how it has drawn more there and started to blend some of the different green colors.   Also there is the box I mentioned.  You move that around with the mouse and resize it with the mouse wheel.  When you click and make a new moving point it is limited to moving within the box.

This thing still doesn't quite do what I want, but I'm not sure if I know what I want.  So maybe it will never do what I want, but I like messing around with this kind of thing so I'll keep working on it and posting about my progress.

Getting Hidden App Data From Your Google Drive

Some Android applications use space on your Google Drive to store data.  You can't see this data by browsing drive the normal way.  You can get access to it if you get the access token from the app and do a few other things.

I use an app to keep some notes and other things.  They require getting the paid version of the app to backup your data.  I wanted to see if I could get it myself without paying for the app.  I found out how to do this from this Stackoverflow post http://stackoverflow.com/questions/22832104/see-hidden-app-data-in-google-drive.  The example there uses php. Since I have been learning Python recently, I decided to see if I could do the same thing with Python.

 There is a pretty good explanation of why you need to go through all the steps you need to go through to get your data in the accepted answer for that post, so I won't go into too much detail about that here.


My First Memories of Coding

The first time I remember writing code was in grade school in the computer lab.  We were learning Basic.  I'm not sure how old I was, but it would have been sometime in the late '80s or early '90s.  I remember they had us write a program that would take some numbers from the user and print out the average.  I had to ask how to do division. I had only seen it with the standard division symbol in math class, not the forward slash.  Soon after that I was able to get Basic on my home PC.  Actually I think it was included in MS-DOS.

At school and in the beginning at home I was using Basic where you had to use line numbers to write your code.  Then to edit a line you had to retype that line with the number.  Soon after that I was able to get QBasic and a book to help me get started.


Python control of Broadlink RM2 wifi remote

I recently got a Broadlink wifi remote.  I have been playing around trying to send commands to it with python.  I found code on github that does most of what I need.  It looks like the device itself doesn't learn any remote codes.  It is all in the app.  The code I found can send codes to the device and get codes from learning mode. I have a bunch of buttons programmed in the app already.  I wanted to see if I could get those codes.  I think I got them today.  The app, called eControls, allows you to backup your setup.  Today I was able to get my backup file from their backup site. Tomorrow I will try to use the codes from the backup.
