Logbook: L+15

Today I got to float all the way back to ATV again, this time taking with me a big full tank of brine.

What is brine, you may ask? Let’s put it this way: brine is what is left over when we are done “transforming yesterday’s coffee into tomorrow’s coffee”, as fellow astronaut +Don Pettit famously said (not sure if he was quoting somebody else!).

As you might know, we recycle urine onboard thanks to a facility called Urine Processing Assembly or UPA. You put urine from the toilet into UPA and you get two products out: one that will become potable water after some further work in the Water Recovery System and then the waste, a concentrate of all the stuff in your urine that you really don’t want to be part of your future cup.. ehm, pouch of coffee.

The brine is collected in the recycle tank: when this is full, we take it out and float it down to ATV to transfer it into one of the big liquid tanks - of course, once we’re done pumping out any water that might have been launched on ATV in that specific tank!

Only the toilet in Node 3 is directly connected to the Urine Processing Assembly. In the Service Module toilet, mostly used by our Russian crewmates, the urine is collected in a tank. Of course, for our water balance onboard we need to process that urine as well, so periodically some full urine tanks will materialize in a temporary stowage location in Node 1 and we will progressively transfer the urine to the UPA.

If you’re one of those who find this somewhat disturbing or even disgusting, try to look at it this way: our spaceship Earth is, among many other things, a giant UPA. We’re just not used to think about the previous history of those molecules of water in our drink: wouldn’t make much sense, would it? On ISS we don’t think about it either!

By the way, I have to plead guilty and admit that I have not contributed to the water balance at all today. But it’s for a good reason: science! I am doing a 24-hour urine collection, so we’ll have to detract from our onboard water all my filled tubes, frozen in the Melfi freezer by now. It’s one of those things that you’re a bit nervous about the first time, because it’s easy to make a mess in weightlessness, but I’m happy to say that it turned out to be smooth and easy!

We’re graduating from Google[x] labs

It’s hard to believe that Glass started as little more than a scuba mask attached to a laptop. We kept on it, and when it started to come together, we began the Glass Explorer Program as a kind of “open beta” to hear what people had to say.

Explorers, we asked you to be pioneers, and you took what we started and went further than we ever could have dreamed: from the large hadron collider at CERN, to the hospital operating table; the grass of your backyard to the courts of Wimbledon; in fire stations, recording studios, kitchens, mountain tops and more.

Glass was in its infancy, and you took those very first steps and taught us how to walk. Well, we still have some work to do, but now we’re ready to put on our big kid shoes and learn how to run.

Since we first met, interest in wearables has exploded and today it’s one of the most exciting areas in technology. Glass at Work has been growing and we’re seeing incredible developments with Glass in the workplace. As we look to the road ahead, we realize that we’ve outgrown the lab and so we’re officially “graduating” from Google[x] to be our own team here at Google. We’re thrilled to be moving even more from concept to reality.

As part of this transition, we’re closing the Explorer Program so we can focus on what’s coming next. January 19 will be the last day to get the Glass Explorer Edition. In the meantime, we’re continuing to build for the future, and you’ll start to see future versions of Glass when they’re ready. (For now, no peeking.)

Thanks to all of you for believing in us and making all of this possible. Hang tight—it’s going to be an exciting ride.

Today we’re unwrapping the best holiday gift we could’ve imagined: the first real build of our self-driving vehicle prototype.  

The vehicle we unveiled in May (goo.gl/qDUtgq) was an early mockup—it didn’t even have real headlights! Since then, we’ve been working on different prototypes-of-prototypes, each designed to test different systems of a self-driving car—for example, the typical “car” parts like steering and braking, as well as the “self-driving” parts like the computer and sensors. We’ve now put all those systems together in this fully functional vehicle—our first complete prototype for fully autonomous driving.

We’re going to be spending the holidays zipping around our test track, and we hope to see you on the streets of Northern California in the new year.  Our safety drivers will continue to oversee the vehicle for a while longer, using temporary manual controls as needed while we continue to test and learn.  Happy holidays!

Google mobile search is getting faster - to be exact, 100-150 milliseconds faster! When you click on one of the search results, the browser begins fetching the destination page… and here's the trick: we also provide a hint to the browser indicating which other critical resources it should fetch in parallel to speed up rendering of the destination page! 

This is a powerful pattern and one that you can use to accelerate your site as well. The key insight is that we are not speculatively prefetching resources and do not incur unnecessary downloads. Instead, we wait for the user to click the link and tell us exactly where they are headed, and once we know that, we tell the browser which other resources it should fetch in parallel - aka, reactive prefetch!

As you can infer, implementing the above strategy requires a lot of smarts both in the browser and within the search engine... First, we need to know the list of critical resources that may delay rendering of the destination page for every page on the web! No small feat, but the Search team has us covered - they're good like that. Next, we need a browser API that allows us to invoke the prefetch logic when the click occurs: the search page listens for the click event, and once invoked, dynamically inserts prefetch hints into the search results page. Finally, this is where Chrome comes in: as the search results page is unloaded, the browser begins fetching the hinted resources in parallel with the request for the destination page. The net result is that the critical resources are fetched much sooner, allowing the browser to render the destination page 100-150 milliseconds earlier.

P.S. Currently, reactive prefetch is only enabled for users of Google Chrome on Android, as it is the only browser that supports (a) dynamically inserted prefetch hints, and (b) reliably allows prefetch requests to persist across navigations. We hope to add support for other browsers once these features become available!
