Tomorrow begins the start of a healthier diet and exercise reigmen. Ugh.

It's been awhile since I was able to consistently exercise and eat right-- Vacation, Overloaded work schedules, and have knocked me off course from my path to healthy living. The result? A weight of ~230 and BMI of 33. Ouch. Reality Hurts. And it is also motivating. Enough to start the same thing I did the beginning of 2010, just a couple weeks earlier :)

This year was the year of Travel and food: Philippines, Europe, China, Hong Kong, Macau. Next year will be the year of savings and internal refinement starting right now. Let's do this how I know best, Geek-style.

A weight management scale that can track daily weight readings and BMI is on its way to the house. I'm already armed with the gadgets needed to view my progress on an excel spreadsheet or through pie charts and bar graphs. Channel that with the motivation to do the unthinkable-- Get back healthy again. I did it once and I can do it again :)

How to flash .img file on Mac OSX

Command Line Interface
==============
1. Download the desired .img file
2. Open a Terminal (in /Applications/Utilities/)
3. Run diskutil list to get the current list of devices
4. Insert your flash media
5. Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2)
6. Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2)
7. Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img, /dev/rdiskN is faster than /dev/diskN). If you see the error dd: Invalid number `1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.
8. Run diskutil eject /dev/diskN and remove your flash media when the command completes
9. External USB disc drives

Installing a public key on a linux box

1) Prep the linux system for remote access:

mkdir $HOME/.ssh

2) Run puttygen.exe on the client to generate a public/private key-pair.

3) Save the private key locally on the client
4) Copy the key directly from the output window of puttygen
5) Paste into the file $HOME/.ssh/authorized_keys as a single line.
6) Under putty, locate the SSH -> Auth -> ensure to select the proper private key file for authentication
