ubuntu on older CPU freezes _crash_

Update 6-23-18:
I may have been very wrong.  On the suggestion of my sister, I opened up the casing of the alienware and blew out the 5 years of dust collected in it...
So far no crashes.... No fans going nuts... no wierdness... Dust... dust bunnies were most likely  cause of all these issues. Simplest explanation is most likely the right one.

Ok, so I'm trying to figure out why my computer refuses to shutdown, or recognize the keyboard or mouse if I plug the mouse in after it boots up.

It may or may not have anything to do with the mouse.
It has crashed on me before where I could not shutdown without either pulling the power supply or holding the power button.

Not sure why this stuff keeps happening on my computers other then they are old (in alienware case) or weak(in the laptop case), and the newest Operating systems may not be compatible with them.

I imagine when new operating systems are designed and built, they do not consider older or weaker machines.

It makes sense.  I don't like it, but it makes sense.  Most people using newer techs are going to have newer computers, or stronger computers.

And well if you can't afford such things, you must not belong to the club.
I may be a bit grumpy today.

It does look like there are OS like lubuntu that you should/can use on older or weaker machines.

So here's some searches, and links.....

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!                      ex16_ASCII.js //Trying to make a comma

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

playing with color in powershell python

Here's a bit I'm working on.  I've discovered I love doing Ascii.  Examples of how to use the color changing escape.  I got a table from StackOverflow: https://stackoverflow.com/questions/287871/print-in-terminal-with-colors-using-python the charts are way at the bottom. So far accurate for me.  def prettyjunk ( self ): # 1 is bold, 0 is plain, 2 is dull text_red = ' \x1b [1;31;40m' stop_color = ' \x1b [0m' text_blue = ' \x1b [1;34;40m' text_green = ' \x1b [1;32;40m' text_purple = ' \x1b [1;35;40m' text_lightblue = ' \x1b [1;36;40m' text_white = ' \x1b [1;37;40m' a_green_at = ( f " { text_green } @ { stop_color } " ) a_red_at = ( f " { text_red } @ { stop_color } " ) print ( f " { text_red } This should be Red. { stop_color } " ) print ( f "
