Encryption is the new gun control

The same people who don't know anything about guns, know even less about computers and the internet.  Get ready to have your digital anuses violated.

Peak social networking

Social networks are bogus. If they have to spam you into joining, you don't need them. If I want to see pictures of my niece I can text my brother, I don't have to go to facebook. If I want to talk to my parents I call them with my cellphone telephone. Hell I am this close to busting out a goose feather, a nib, and some parchment. I would rather use any other form of communication than be a steer lead to data collection slaughter.

P.S. Linkedin stop trying to trick me into joining your bullshit website.

P.P.S. Twitter is sometimes funny.

TRS-80 Model 100 Super Mario Brothers Theme

I have been messing around with interfacing my raspberry pi with the keyboard and somewhere in the future the lcd.  Yesterday I was bored and decided to fool around with the speaker.  I found this post and followed it to figure out how to work the speaker. I then found this post that has code to play the mario theme using an arduino. I took his code and melded it with the softone example from wiringpi to make it work on the raspberry pi. I also added some code from okLed.c to get the ACT light to blink in time with the song kind of. The code I ended up with is is below.

  Arduino Mario Bros Tunes
  With Piezo Buzzer and PWM

  Connect the positive side of the Buzzer to pin 3,
  then the negative side to a 1k ohm resistor. Connect
  the other side of the 1 k ohm resistor to
  ground(GND) pin on the Arduino.
