Thanks +UNITED AIRLINES​!!!

I managed to loose my sunglasses in the depth of my seat. It took 3 flight attendants, 2 flashlights, one pair of tongues and some long hook-device to get them out again. Your crew of UA 863 rocks!!!

Day 2 with my +Ghost Drone. Very unimpressed so far:

1. Instructions
Setting up the Drone was OK. But then the instructions for the Gimbal did not match my device (different cable colors). I connected it as good as I could see fit (blue-blue, white-white). But the app doesn't recognize that I have a Gimbal (though it does get stabilized).

2. Support
I asked Ghost support about this problem, but didn't get any response (after 1 week!)

3. Stability
Compared to my 2 year(!) old parrot, the ghost is a step back. The parrot drone takes of and flies in an amazing straight line. The ghost drone goes mostly straight. This makes flying in an area that is not completely empty and open difficult (e.g. backyard and street).

4. Controlling
The fly-by-map mode of the ghost is interesting (you point on a map and ghost drone flies there). But I think I prefer that fly-by-tilt mode of the parrot (the drone flies into the direction that you tilt your device).

5. App
The Android app crashed a few times. But almost worse during normal flight mode, the Android button bar (with the home and back key) overlapped with the app and made the height slider inaccessible (see screenshot).

6. Follow Mode
It required some imagination, that the ghost drone really follows you. It sort of turns and flies into the right direction by it's very imprecise. I had to make more then 5 steps before the drone even started to react.

7. Automated landing
On my first try on our street, the drone landed once hard enough to bend the legs and leave some marks. But today, the drone ran low on battery and what should have been a controlled landing broke BOTH LEGS and THREE PROPELLORS (but the protectors were unharmed - shouldn't it be the other way round?) - see photo.

I'll fix the drone, but not sure how much fun I'll have with it. Maybe I should have forked off additional $$$ and get a Beebop drone ...

+Mark Striebeck Prop guards shouldn't be able to flex enough to contact the props, or -- as you note -- their whole point is moot. I do usually run prop guards despite their minor weight and aerodynamic hits because I frequently land in situations on ground where a tilt over is not unlikely no matter how slow the speed. As for your crash, that hover you describe is the probable clue. While a power failure is not impossible, I'm betting it thought it was already on the ground when it cut the power. At least in the APM world, the usual algorithm is to use the baro on the way down but make the final determination of landing based on lack of downward movement as determined by the other sensors (it's all tunable).  Some people add a physical touchdown switch but that usually isn't necessary.

I am sooooo late to the party with my image of Lovejoy.

I took this data back in January, but it took me a long time and many tries to figure out how to process it: a) this was my first comet, b) had to fight with extreme vignetting, and c) the light pollution in our backyard (plus the moon).

I had to use the whole bandwidth of processing tools: CCDStack, Pixinsight, Nebulosity, Photoshop.

I wish I had taken more Luminance data - the tail isn't somewhat washed out.

If you are interested in the whole process: http://mstriebeck-astrophotography.blogspot.de/2015/02/first-comet-image-lovejoy.html

Comet Lovejoy travelling our skies.

I took these images a month ago, but it took me a long time and many tries to figure out how to process the data - mostly because of the light pollution in our backyard which washed out the images.

The point here is not if he compared the protesters to ISIS or not. The point here is that this guy clearly has no f###ing clue what he is talking about when he compares unarmed protestors who execute their democratic rights to a heavily armed militia that conquers large areas of countries, beheads people and tries to establish a state.

This is Scott Walkers I-can-see-russia-from-my-house type attempt to give the impression that he has any foreign policy experience.
Walker’s comments didn’t appear to hurt him among those who attended the CPAC conference. He finished a strong second in its straw poll Saturday.

This guy is GWB: The Sequel. I expect he is going to run away with the nomination in spite of saying something profoundly stupid every couple of weeks.

Are you f##-ing kidding me? Not just the stupidity of +Lenovo ​, but also that this isn't a criminal act!
News broke last night that Lenovo has been shipping laptops with a horrifically dangerous piece of software called Superfish, which tampers with Windows' cryptographic security to perform man-in-the-middle attacks against the user's browsing.

It gets worse. Superfish doesn't do proper validation and accepts any self-signed certificates with the domain name in the alternate field. Cracked key not necessary.

"Debating the nature of policing is very important but I worry that it has become an excuse at times to avoid doing something harder."

So, it is possible to make non-partisan statements in DC. If James Comey ever runs for any public office, he has my vote. Avoiding oversimplification and making thoughtful statements has become such a rare art :-(
FBI Director James Comey took on the issue of police and race relations Thursday challenging police to avoid "lazy mental short-cuts" that can lead to bias in the way they treat blacks and other minorities.

Awesome analysis of the Greek negotiations with the European Union - and Germany in particular. Not intermingling it with pro or contra austerity opinion. Just focusing on how Greek opened up its effort to renegotiate the terms.
Greece is back where it started in poker contest with Germany and Europe. Athens has shown its best cards too early and has no credibility left if it wants to try bluffing

The article unfortunately starts from an assumption which I think is wrong. It assumes that Germany is most interested in avoiding a debt write-off. It claims that this matters more to German voters than structural reform in Greece. But, knowing the German psyche, I believe this assumption to be wrong. Germans are happy to give money, but only to people who they perceive to conform to German ideals: austere, hard-working, rule-abiding, tax-paying, incorruptible. If they felt they could make Greece into a country that resembles Germany, they would happily give trillions. They did that with the former communist East Germany, for example. What German voters care about is not whether the Greek get more money, but whether they are austere. Do you think I am right about the German psyche? I think this is quite incomprehensible to non-Germans, but you are German, right?

Story
Introduction
I live in Silicon Valley, work at Google and am married to a wonderful wife with 2 awesome children.

I am working on YouTube on he creator side. Before that I worked on Gmail, testing infrastructure and Ads at Google.
I used to be very actively involved in the Agile community (I even served on the board of directors of the Agile Alliance). Now, there is very little time for that.

In my spare time, I am taking astro images. And in winter, me and the kids are avid snowboarders.
Bragging rights
I'm the Forrest Gump of IT. I had so many friends in school and university who knew exactly what they wanted to do later in their life and how to achieve it. I never had any concrete plans. I always went with something that felt cool - and ended up at Google in the Silicon Valley.
