This is for all of you ROS (Robot Operating System) users out there.
If your ROS topics won't publish, make sure that you subscribe to the topic AFTER it is advertised, otherwise it won't work. For example, if you have one program that is subscribed to an advertised topic, then the program advertising the topic is closed, the topic is unadvertised (right?). When this program runs again, and the topic re-advertised, it will not automatically reconnect with the program that was already subscribed to this topic - resubscribe!

Can't play DVD's in Ubuntu? Try this...
So I ran into a problem the other day on a clean install of Ubuntu while trying to play a DVD - it didn't work. I did some looking, and found the answer pretty quickly.
Make sure you have either ubuntu-restricted-extras or libdvdread4 installed (sudo apt-get install ubuntu-restricted-extras)
Open a terminal and run: sudo /usr/share/doc/libdvdread4/install-css.sh
Ta-Da! A reboot might be necessary, but that should get you playing.

Cowboy Cauldron
Ah, the Cowboy Cauldron. So, ever since I saw these on Huckberry, I've been completely sold. Love at first sight. Like I need one in my yard. Right. NOW.
Unfortunately, I currently don't have the cash to shell out for one of these little (er - not so little?) beauties, so this will have to do in the meantime.
Because everything's better in steel, right?
What's more refined that a flat cap, sheepskin gloves,
and a giant steel cauldron of fire? Irish countryside not included.
"Did you say you just cooked a cow? A cow cow??" Yes. Yes I did.
Which one do you prefer? Personally I find it difficult to resist the alluring call of the Ranch Boss, but what can I say? I like fire.

$$$ Get Access to Your Flash Cache! - Windows 7 Edition!$$$
In a follow-up to my previous post, here is some info for accessing the Flash cache in Windows 7. When using Chrome, simply open a Windows file folder and navigate to
%LocalAppData%\Google\Chrome\User Data\Default\Pepper Data\Shockwave Flash\
and you should see your Flash media buffering here. Simply rename the *.tmp files to *.flv (or the container of your choice), and voilĂ ! Enjoy with the media player of your choice (e.g. VLC and a nice Chianti.)
Did this work for you? Did I miss anything? Let me know!

Can-Am Spyder Roadster - The Family Man's Motorcycle
Ode to the Hustler - Joey Roth
Yeah, not that Hustler. Designer Joey Roth designed a series of graphics for the first issue of 48 Hours Magazine, Hustle. What he came up with is pure genius.
Hustling is creating something from inspiration, mediated by an uncompromising picture of reality, then launching it with precision into the world.
Grind: Disciplined, incremental movement through reality towards a goal
Dream: A good idea that loses potency as it encounters reality
I have Huckberry to thank for this find. You can buy prints from Huckberry (while the offer lasts) or from Joey Roth's website.
