Using TkDiff with Subversion on OSX

Step 1: Download and install TkDiff

Download this from SourceForge, unpack the disk image, and drag the tkdiff application to your Applications directory.

Step 2: Set up an alias to run TkDiff from the command line

In bash on my machine, I added the following to my PATH in my ~/.bash_profile so I could run it via the command line.

Step 3: Tell Subversion to use TkDiff instead of the default

You'll need an adapter script so Subversion can call TkDiff correctly.
# Configure your favorite diff program here.
# Subversion provides the paths we need as the sixth and seventh
# parameters.
# Call the diff command (change the following line to make sense for
# your merge program).
Then add the following to ~/.subversion/config to default to this diff method.
diff-cmd = /Users/tgnourse/scripts/

Step 4: Success!

Now you can diff all your edits like so:
svn diff
In addition, TkDiff has built in subversion support so you can also diff single files like so:
tkdiff your/file.ext

Writing to / Reading from a Serial Port on Linux

echo -n "?" > /dev/ttyUSB0

 tail -f /dev/ttyUSB0

The beauty of this is that this can happen while something else is connected to the port which makes the tail command great for debugging.

Getting a Blackberry Tour Unlocked on Sprint

This is a free service. All you need to do is be able to prove you own the account (i.e. remember your PIN number or secret question).

Step 1: Call the Sprint International Desk at (817) 698-4199 and select option 3 to get a real live person.

Step 2: Tell them your Sprint phone number (the one that goes to your Tour) and answer any verification questions.

Step 3:  They should now give you your unlock code. To unlock your phone all you need to do is.

  1. Options -> Advanced -> SIM Card
  2. Type 'mepdmep2' (a dialog should pop up)
  3. Enter your unlock code
  4. Reset your phone by pulling the battery
That's it! Kudos to Sprint for making this so easy, if a little hard to discover.

Tethering on Blackberry Tour (9360) on Sprint on Windows

  1. Pair the Blackberry and your computer (should be self explanatory)
  2. When setting up the connection enter "#777" for the phone number
  3. Leave the username and password blank
  4. Click "Dial" to start the connection
Note that despite the fact that this is listed as a "Dial Up Connection" its really just using the phone as a Bluetooth Modem like it should.

Hauppauge ImpactVCB

I purchased this card intending to use it on my Ubuntu Linux box and it worked fine. All I had to do was make sure I set VLC and Motion to use NTSC .. silly Europeans set PAL to be the default.

Selecting an input is done by selecting the channel number.

Now, despite the fact that it has 4 inputs (1 super video and 4 analog) it can only capture from one of those inputs at a time :( I guess this is why it was $40 and everything else was $100 or more.
