How crazy is this !! ;-)

By now if you’re as RSS-addicted as me you’ve probably seen the excellent “How to remain calm” Chrome OS video. Like the previous potato-powered Chrome ad, excellent job from the marketing guys at Google!

However this time with my fellow geeks at Jamendo we noticed an equation hidden at 2:23 in the video. We then proceeded to lose several hours of productivity running it through Wolfram Alpha...

Jamendo geeks solve the hidden Chrome OS equation (and win a Cr-48 netbook)

All we got was X = 900.91/191605050401140404051920181525 ~= 4.7*10^-27 and we were not even sure of this one number because of barely readable numbers in the original video. At this point we were quite sure that there was something to find (and hopefully to win) but still had to find a way to give a meaning to this number.


The first path we explored was in Physics, 1.66*10^-27 being the atomic mass constant u. Having X=2.83u didn’t make much sense: too far from 2.0x or 3.0x where the closest elements I knew are. Then my friend Joachim Rambeau tipped me off with an idea on “Chrome UX” being the name of the team that released the video. There was an X in there! With the equation X=(U/Chrome), U being the mass of Uranium (~238u depending on isotopes) and “Chrome” the mass of Cr-48 or related isotopes, we found ourselves very close to the 4.7 ballpark. I posted this as a comment in the video, without much hope of it being the definite answer.


So we left this for a few hours and got back to work. Funny coincidence? The current work at Jamendo is actually building a Jamendo Pro player on cheap Android tablets ;-) So we didn’t quite leave the Google world...


Anyway, while having drinks at the office at the end of the day (Yes, Jamendo is almost as cool to work at as Google) , we realized “900.91″ did actually reference the url shortener. The division obviously meant a slash in an URL, and then we had to make sense of the 191605050401140404051920181525 to find an URL. But the excitation was growing, we knew we were on the right path this time!


Unfortunately, at this point I had to leave and go catch a TGV back to Paris. I’m actually still on the TGV as I’m writing this, thanks to Android tethering ;-) Anyway, I tried to convert the 30 numbers into 4 characters, like all URLs. Didn’t have much luck, I was trying to prepend “00″ at the beginning to have 32 characters, but couldn’t make sense of the resulting sequence “00191605 05040114 04040519 20181525″.


That was when I noticed there were far too many zeroes in that sequence, even without the ones I added... So I tried different splits, and ended up with “19 16 05 05 04 01 14 04 04 05 19 20 18 15 25″.


There, any geek would have known what to do! I translated it to letters and got “s p e e d a n d d e s t r o y”. Obviously, at this point my fingers were very shaky! But I managed to type in my browser and got to a form telling me that I was the “first to figure out our MENSA-certified puzzle” and would receive a Cr-48. WIN ! ;-)


Here is a screenshot of that page:

I think I was indeed the first because now the link just says “The form you are trying to access has either expired or reached its maximum registration limit.”. Well, that’s pretty cool if you ask me ;-) (Funny details, while submitting the form, I crossed the Luxembourg/France border, the tethering went off and I started sweating they were going to check the IP address but I was still able to submit the form from France)

Big credits must go to the to the tech team at Jamendo: our genius lead developer Vincent who showed us the video first, our incredible Android hacker Mauro who helped me a lot with the actual equation, my fellow Jamendo Co-Founder Laurent and my own personal Physics expert Joachim Rambeau.

Anyway, congrats to Google for being such nerds. The video itself is really funny, embedding an easter egg is even cooler, and, well, most people I know including myself couldn’t go back to anything else than Chromium/V8 anymore.

I’m obviously quite happy to have won the Cr-48 notebook, I also hope Google may start giving a little more attention to Jamendo! If you pardon the plug, we’re the biggest Creative Commons music repository, and we’ve never succeeded inking a deal with YouTube about these hundred of thousands of CC music tracks (be it AudioSwap integration, proper CC attribution, revenue sharing, …). Let’s hope that will happen in the future!

PS: Hey Google, could we also have one of the destroyed notebooks to include in our gallery ? ;-)

PS2: The form says that I should live in the U.S. to receive the notebook but sorry that's not the case obviously! I left the address of a U.S. relative but I can't imagine it being a real issue just for one laptop. I'll keep everybody updated as I get contacted by Google.

This month, electronic artist Professor Kliq shares with you his best tips for increasing exposure on jamendo. Professor Kliq is a top-selling artist on jamendo PRO and has seen his fan-base grow dramatically in the three years since he joined jamendo.  Read on to find out what he believes contributed to his success and use his tips to gain exposure yourself as a jamendo artist!

Jamendo has been the backbone of my success in my music career so far... if there's one thing I tell people about Creative Commons and technology today and the way it has impacted society, culture, and thusly the music industry, it's that you never know WHOSE hands your music will end up in if it's free and on the internet. There is definitely a sense of community in the CC world and that has shown with the support of my fans - a number which grows every day thanks to Jamendo and the doctrine of the CC license. If I could give any advice to anyone just starting their presence on Jamendo, it would be this:


  1. Space your releases and make sure they're of a reasonable length. Don't just upload a single track every time you finish something... people who enjoy your work want to be able to put it on and listen to it for a while, not have to hunt and peck through your slew of single releases and make a playlist. Also, when you create an "album", you have control over the structure of the entire thing... track selection is as musically relevant as the music itself and people respect that.
  2. Be patient. Like anything, it takes time to garner a following... I've been on Jamendo since 2007, so it's taken a while to get as many listens as I have, but the right people heard it and the listens have grown almost exponentially since.
  3. Participate in the community... go through and find some other works that you like. It's a great help to see what other artists like yourself are up to across the globe. You'll end up making friends this way and networking is key when your music is on the internet.
  4. Keep track of where your music is used - every use is another piece of your portfolio as a musician.
  5. Keep in touch with the people who use your music... you never know when they're going to need you again and if you're on a personal level, you'd be surprised where it can take you in your career.
