ROS Topics Won't Publish?

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.)

Can-Am Spyder Roadster - The Family Man's Motorcycle

Yes, you read it right. For those who love the feel of the open road, wind whipping in your hair (or past your law-abiding helmet), without the quiet nagging guilt of leaving a family parent-less, comes the Can-Am Spyder Roadster - The Family Man's Motorcycle. Often dubbed a 'tricycle', you should immediately dispose of the images of red-painted childhood wonder. This is no kids toy. Instead it is a shiny, gleaming machine of awesomeness. And it's coming to a road near you... take a look:







One of the safety selling points is the (supposed) fact that with the third wheel up front, it makes this ride nearly impossible to roll. Personally, I would like to see some hard data on this, but that's just me. That said, when I was doing research online to try to find how many accidents involving these platforms rolling had been recorded, I found nary a one. Well - I found one. A news purveyor in CA recorded a deadly accident involving a few first time riders taking two of these platforms into the mountains. The article made it a point to say that the Roadster was obviously not as safe as it purported to be. What the reporter failed to mention was just how the riders were able to flip the Roadster. Banking too hard, too fast? No. No, they were able to accomplish this feat by driving them off the side of a mountain. I don't know many vehicles that could survive that kind of rigorous activity unscathed. At any rate, with a few exceptions, this seems to be one safe (and sweet) ride.


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.
