Introducing the Domino's DomiCopter!

I wonder why innovation and Pizza are so tightly linked. Remember back in 1994 when you could order the first pizza over the internet? Or the famous Bitcoin pizza? Well, here is the first drone based pizza delivery :-)

 

Anyway, I don't believe so much in the cost efficiency of drone based pizza (or tacos) delivery. However i'm sure these kind of logistic use cases will be disruptive in some industries.

First attempt at estimating the state of an AR Drone

This is my first attempt at estimating the position of an ARDrone by integrating the motion data through time. You can kinda see I have been flying two square patterns.

 

There is a lot of noise obviously (both sensors and wind) which are the cause of this not so precise tracking. Next step is to integrate observations derived from the camera into a proper Extended Kalman Filter. That's the tricky part :-)

An inspiring one-hour interview of Elon Musk at D11

Elon Musk is such an amazing entrepreneur. Listening to him is both inspiring (let's dream big!) and depressing (not everyone can climb big mountains). In this video, he talks about electric cars, building mars colonies and going from LA to SF in 30 minutes with his HyperLoop. He also talks about wa...

Drone Adventures Uses UAVs to Help Make the World a Better Place

Ok, I admit, over the last months I got myself a real passion for flying robots. Yet, most of my friends & familly have been literally laughing at me and my 'toys'. This is an annoying cognitivie dissonance, of thinking you are working on world changing technologies when other just see you as playing with toys.

 

So, it was reassuring to come accross Drone Adventures and this video. Good to see a few other folks out there also believe these little toys can make this world a better place, and not only a big brotherish distopian future.

 

Update: These are other life savings flying robots. They will help us better understand tornadoes and provided key information to first aid responders in emergency situations.

I've also fallen in love with #indieweb over the last few months, and have made a commitment to moving over to my own platform, which I'm on track to do by the end of the month.

There was some leadership drain, but there were a lot of stalwarts in the federated social web community. Honestly, though, I think Tom hit the nail on the head, and the movement was stymied by complexity (and the bureaucracy that you described). Brad Fitzpatrick's frustration at the last Federated Social Web Summit was also spot on.

Indieweb will succeed, I believe, because it's easy. You can get *something* up and running in an afternoon. There's lots of great software springing up (and I hope mine gets to be part of the mix). The next trick is, finding the business cases for building these features in, and keeping them in.

I'm lurking on the channel a lot!

I wanted to come back and say: I think the federated social web software that was produced, and is being produced, is amazing. Honestly showing us the future, way ahead of time. And my comments above about complexity should not detract from that; the point is that the platforms people are writing abstract that complexity away from end-users, which is great.

Similar questions have been asked regarding Identi.ca's upcoming migration from StatusNet to pump.io. Evan Prodromou has always wanted to give people software for making their own federated networks, but what they wanted was an open alternative to Twitter -- in other words, a central gathering place. And that makes sense, because in federated networks the biggest problem is discovery. Consider the hoops you must jump through to make sure all your contacts know when you change your e-mail address or IM handles.

Also, not everyone has the skills and disposition to rent a VPS and set up the complex software infrastructure required to run something like pump.io, especially as it has nothing to do with the usual LAMP stack. At least Diaspora is built on RoR, which is provided even on shared hosting accounts.

Ultimately, having a balance serves people best, like with WordPress the software and WordPress the service. But that's not what the federated networks crowd wants...

The question we have to ask ourselves is "Why?". Answers assuming bad intentions are missing the point.

There's a deep reason why email is the only successful decentralized network. And also the worst regarding tho spam, ease of use and problems.

Changing and admitting failure is part of Google culture and, for me, the biggest reason of their success.

We can say that they honestly tried. They tried really hard.

But it is simply not working. They are limiting themselves, they can't evolve the way they want.

I'm not saying that it is "good", I'm just saying that it is understandable and very predictable. I remember saying in one of my conference where someone told me that "XMPP was successful at taking over MSN" : "It's not XMPP, it's Google. The day Google drops XMPP, we will discover that only a tiny minority cares about XMPP."

I wish I was wrong…

"The good news is, we do not need Google to build the open web for us. "

If that's true, than I don't understand all the whining and crying is all about. Yeah it sucks when a service is closed down but that happens everyday. Why is it such a big deal when Google happens to do it - since *we* don't need them anyway.

@zaidira I think the bitterness comes from the perceived movement in google's culture. A move from their hacker origins to a corporate culture where the masses dominate. Time to move on I guess, but the effort required to replicate google's quality products is a little daunting.

Seriously, they didn't try very hard.

The XMPP community did, bending over backwards to accommodate them. A vast amount of serious effort has gone into reworking S2S authentication, for example, specifically to address Google's requests to make supporting Google Apps domains securely simpler for them.

Jingle was initially designed by Google, but yet they never implemented the latest standards as they were developed - and yet this was their area of greatest interaction.

I've even heard that some of PEP - another set of XMPP extensions they never bothered to implement - was guided by Google so they could deploy it.

Google have been known to use open standards, but they're rubbish at contributing to them.

Google has never cared about the "open web"... it cares about Google being able to access all information out there. It doesn't give a damn-- and never has-- about other people being able to access information.

It's sad that a generation of people have been deluded into thinking google is somehow a force for good. They are blatent patent trolls-- suing Apple (via Motorola) for standards essential patents, which started the whole patent war (Apple sued them in defense)... which is pretty ironic given that android is a ripoff of Apple's IP... all the while Google's publically running an anti-IP campaign (Because as an IP theif they want to get away with it.)

Yet people ignore the fact that Google is the patent troll that started the whole thing and delude themselves into thinking that Google is "right" ... becuase they want to own an android phone without guilt.

At this point, I have no sympathy for people who are so deluded that they think google is anything but evil. They have been evil (and uninnovative) for a long time.

This is not surprising given they make their money by violating people's privacy.

But the deluded fools think "oh this service from google is free, they must be benevolent!"

There's not a whole lot of transparency from Goog as to why they make these decisions, so I can only imagine that as they've evolved into a purely commercial company supporting and championing interoperability has become a cost center that runs against some walled-garden vision. Who knows, but I think its sad.

""Changing and admitting failure is part of Google culture and, for me, the biggest reason of their success. We can say that they honestly tried. They tried really hard. But it is simply not working. They are limiting themselves, they can't evolve the way they want.""

I think the problem is not that Google is abandoning these protocols. (Lots of companies never bothered to use them in the first place, and we're not complaining about those guys.) The problem is they're talking out of both sides of their mouth.

From one side: open is great, Google is open, Google is better than our competitors *because* we're more open. From the other side: we're abandoning a bunch of the most popular open protocols because they're just not working for us (you claim).

I think it would be drastically different if they had said, hypothetically, "CalDav isn't flexible enough for the needs of Google Calendars, so we're proposing a new open standard, SuperCalSync, and inviting everybody to try it out with us". That would show that the existing protocol sucks (well, it kind of does!), but that they think openness can work. But they're not doing that.

I would *love* for Google to put out a press release that said: "We tried open source and open protocols. Nobody cares, and it holds us back. We're going to do everything behind closed doors from now on. Deal with it." Then at least they'd be honest.

It's amusing to me that Google's apologists defend the company for almost any action, even when they would be howling if a similar action was taken by Microsoft of Apple. For some reason, there's a portion of the tech crowd that's bought the insane notion that Google has everybody's best interests at heart, so we can trust them. I appreciate and use some of Google's products, but I trust the company less and less — because their actual track record is nowhere near the record of altruism that Larry Page and his supporters would have you believe. (Just to be clear, Google isn't supposed to be altruistic. I'm just sick of the hypocrisy and the dishonesty about it.)
