Absolutely agree: "The longer we wait to get autonomous vehicles on the road, the more people will die. ... That is the real moral question of autonomous cars: Why aren't we getting them on the road faster?"

I personally have said two years ago, that I believe that my kids won't need a driver's license any more. I very much hope so.

And I hope even more for a more advanced and less individual transport system and for less needs for transportation in general.

Can you imagine, for example, that we still have daily commutes in twenty years? If that's the future, we will have failed!

BTW: I do have a driver's license but do not own a car. I personally do not like driving by car and prefer to use public transport. I also do lot's of walking and some cycling. My partner does own a car and believes our kids will have to get a driver's license :-)

I'll stop driving when you rip the keys out of my cold dead hands.

I love to drive, I only drive manuals. My commute from my house was 100km (one way) and I loved it!

I wanted to give a quick shout out to two Android apps that designers and app UI developers might find very useful in their work.

Huge thanks to both of the app teams! Android developer and designer community is amazing. Many of us spend our free time to make everyone's work easier.

New documentation about debugging various common kinds of native crash up on source.android.com this week: https://source.android.com/devices/tech/debug/native-crash.html

I actually wrote this to help folks in QA triage app compatibility crashes better, and it seems to have been helpful. The original internal version was based on actual app crashes from bugs.

Since our older son Linus had his birthday today, I wrote some code to play "Happy Birthday" using Android Things with a piezo buzzer.

Not the best sound - but well, he likes my tinkering with this stuff, so it was worth it!

And why not play Auld Lang Syne since I'm at it. So a belated Happy New Year to all of you!

And, yes, the lightshow definitely needs some more love :-D

Whow! This headline by the one of German's biggest newspapers a bit over the top - even considering that we are quite some privacy concerned folks.

"Nest soon to supervise Germany"

I thought a bit about what useful stuff to do with Android Things. And today the family council has decided: We are going to build a remote controlled car.

The only problem with that are my meager mechanical abilities. Hopefully the kids can make up for them :-)

Not sure about which components to use, but this tyre  and motor look pretty good for a start (German site: https://www.roboter-bausatz.de/460/roboter/auto-reifen-inkl.-getriebemotor-1-48). Anything else is open for recommendations. It's always reasonable to start with a hapazard detail :-D

Reports of Wear's death have been greatly exaggerated :-)
 
Dec 2016: Every second tech blogs writes some far fetched articles about the death of Android Wear and smartwatches in general.

Jan 2017: TONS of new Android Wear watches announced by multiple manufacturers as well as a flood of other watches.

I agree. This is still only an accessory (at least to me). And that must be cheap - or long-lasting. Since we can forget about the latter, the former has to be it.

After looking into deeply nested layouts on Facebooks Yoga layout and RelativeLayout [1], i wanted to compare the performance of deeply nested ConstraintLayouts. The key takeaway is: If you are having slow layouts with RelativeLayout you should update to the ConstraintLayout.

So hows does the ContraintLayout compare? The benchmark is the Yoga layout with a max depth of 500 levels (1000 ViewGroups) in 2.7sec. The good news: unlike the RelativeLayout, which topped out at depth ~8 (16 ViewGroups), the ConstraintLayout is actually able to handle such a depth. It took the ConstraintLayout ~3 sec to calculate its layout with a depth of 500 (1000 ViewGroups). Very close to the Yoga layout. Pretty good.

So how far down the rabbit hole can you take the ConstraintLayout? All tests were conducted on the Nexus 6P without "largeHeap" enabled. The deepest layout that could be created without an OutOfMemoryException was 1900 levels (3800 ViewGroups) in 46 sec. That is pretty deep.

Concluding this experiment it can be said that there is no reason to use the RelativeLayout anymore. If you need to use a cross platform layout, the Yoga layout is a good choice (although it is missing some features). When you need the absolute maximum depth (which you should not go for) and want a quick layout you should opt for the ConstraintLayout.

Keep in mind that the experiments were conducted on a particular layout configuration. Your mileage may vary when using other types of views/layoutparams.

Google is known all around the world. Everyone is 'googling', checking on 'maps' and communicating in 'gmail'. For simple users, they are services that just works, but not for us.

Technology built to uplift and connect people should not be turned into a tool of oppression. Read our open letter to the tech industry, published as a full-page ad in Wired Magazine today. As Trump takes office, we're calling on tech to delete logs, encrypt data, shed light on government demands, and fight for user rights in court & in policy. Read more and see the ad: https://eff.org/defend-users
