Subsonic 6 Random Refresh Rate

Posted in Uncategorized by cdeschenes on November 20, 2016

The “random” section of Subsonic 6 does an automatic refresh of the page every 20000 ms. I find this way to fast to look and make a decision. So how do I change this?

Im running Subsonic on Ubuntu:

  • cd /var/subsonic/jetty/a7857c/webapp/WEB-INF/jsp
  • sudo vim home.jsp
  • Search for 20000: / 20000
  • Change to 90000
  • Save and exit.

Replace With: Sleeping Sucks\r\nI can not sleep!


Match anything inside parentheses:

Search Mode: Regular Expression

Find What:  \(([^()]*)\) Starts with a space!

Replace With: emplty

Getting PicKit2 working in OSX

Posted in Uncategorized by cdeschenes on November 1, 2014


Extract files


  • Mac OSX 10.5 is required to run it along with the latest version of Java.
  • You need to copy pk2cmd and PK2DeviceFile.dat files into /bin folder, even if you have manually installed pk2cmd before.
  • To do that, open a Finder window and press CMD+SHIFT+G then type in “/bin” (without the ” “).
  • Drag and drop the 2 files, enter your admin password and you’re done.

Or by terminal:

  • copy pk2cmd to /bin
  • # sudo cp pkcmd /bin
  • Copy PK2DeviceFile.dat to /bin
  • # sudo cp PK2DeviceFile.dat /bin

Plugin your USB PicKit2

Run PicKit2-Programmer

If you get the message that the PK2DeviceFile.dat can not be found then run the following command.

# sudo chmod 777 /bin/PK2DeviceFile.dat

Use a USB to Serial adapter on a Macbook

Posted in Uncategorized by cdeschenes on October 22, 2014

Open terminal app or download iTerm

Type: ls /dev/tty.\*

plug in USB to Serial adapter and re-run the previous command. You should see a new tty.XXXXXX that is for the USB device.

Mine is /dev/tty.usbserial-A702XH8W

Were going to use screen to connect to a remote terminal VIA USB. You need to specify the speed of the connection. The defaults are defaults to databits=8, parity=none, stopbits=1

screen /dev/ttySX baud_rate,cs8|cs7,ixon|-ixon,ixoff|-ixoff,istrip|-istrip
  • /dev/ttySX: Linux serial port (e.g., /dev/ttyS0 [COM1] )
  • baud_rate: Usually 300, 1200, 9600 or 19200. This affects transmission as well as receive speed.
  • cs8 or cs7: Specify the transmission of eight (or seven) bits per byte.
  • ixon or -ixon: Enables (or disables) software flow-control (CTRL-S/CTRL-Q) for sending data.
  • ixoff or -ixoff: Enables (or disables) software flow-control for receiving data.
  • istrip or -istrip: Clear (or keep) the eight bit in each received byte.

Open a terminal windows and type:

screen /dev/tty.usbserial-A702XH8W 9600
