Google Launches AMP For Email To Bring Web-like Actionable Content To Gmail (venturebeat.com) 98

Google today announced an extension of the AMP (accelerated mobile pages) program to include another popular communications medium. From a report: The internet giant unveiled the Gmail developer preview of AMP for email, a web-like experience designed to make emails more engaging and interactive. One of the key benefits of AMP for email will be that content within an email can be updated, and recipients will be able to browse email content much like they would a web page. So an email from Pinterest, for example, could contain actionable content, allowing users to Pin content to their own Pinterest account without leaving Gmail. Or they could complete a form to arrange a meeting, fill in a questionnaire, and do just about anything -- all from within the email itself. It's clear that marketers will be a major target audience here.

The ring is above the equator. I was surprised to read the rotation period is 3.9 hours for something that large. Then I started wondering, "that's gotta create some significant (relative to gravity) centripetal force. How much would gravity be reduced if you were standing on the equator on the long axis?" Calculemus!

Haumea (according to Wikipedia):
Size along longest axis: 2322 km
Mass: 4e21 kg

Based on this we can calculate centripetal acceleration using a = v^2/r:
v = angular velocity = 2.322e6 m * pi / 14040 s = 519.571 m/s
r = 1.161e6 m
a = 0.2325186 m/s^2

The acceleration due to gravity at that point on the equator is g = G*M/r^2:
G = 6.674e-11 m^3/kg/s^2
M = 4e21 kg
r = 1.161e6 m
g = 0.19805315 m/s^2

Which (if my calculations are correct) means that centripetal force at that point is actually 17% HIGHER than gravity. You'd have to hang on (it wouldn't be hard: if you weighted 200lbs (91kg) on Earth, you'd only need 11.25oz (320g) of force). Maybe that's where the ring comes from? Material just rolls off the planet?

Note: This assumes lots of stuff that may be incorrect.

Note 2: This would mean that an object attached to the surface at that point, if released, would immediately enter into an elliptical orbit with a period GREATER than the rotational period of the planet. You could very easily launch and capture orbiting vehicles with tethers extending some distance up from the surface, assuming the surface was solid enough to anchor them. Alternatively, you could build a hangar structure, and orbiting vehicles, facing retrograde, would land on the ceiling.

Refresh Is Sacred (tbray.org) 193

Several Slashdot readers share a blog post: There are two kinds of client applications: The first kind has a "refresh" or "reload" button to make sure your app's in sync with its server's view of the world. The second kind is broken. Of late, I have to deal regularly with several apps, notably including an emailer and car-sharing service, that lack such a button. I can imagine why -- a customer focused product manager said "Steve Jobs taught us that fewer controls are better and we should just take care of making sure we're in sync with the cloud. So lose the button. Except, it doesn't work. Apparently nobody in the world is smart enough to arrange flawlessly reliable hands-off client/cloud synchronization. There are times when you just know that what you're seeing on the screen is wrong and if the stupid app would just assume everything it knows is wrong and ask for a brain transplant from its server, things would be OK.

Running it in Golly on my PC right now it maxes out at 4-5 million generations/second with a step size of 8^6, periodically slowing down presumably to hash some new cell configuration. It uses ~550MB of RAM. I've run the other metapixel patterns that come with Golly, but this one is mind blowing to see.

Ironically, there's not much to look at, since there doesn't seem to be a display of the Tetris board built in.

Comment Re: Contamination (Score 3, Informative) 74

It was a worry over biological contamination. JPL (and NASA) have very specific protocols for planetary protection. Huygens went through some extreme decontamination prior to launch. Cassini, as an orbiting probe, not so much. Also, at launch we didn't know as much about the Saturn system and it's moons.

Specifically, we learned that Enceladus has a large subsurface ocean, at the bottom of which may lie hydrothermal vents. Since those on Earth are often teeming with life, we didn't want to risk contamination of Enceladus' oceans.

$782,000 Over Asking For a House in Sunnyvale (mercurynews.com) 266

An anonymous reader shares a report: A house in Sunnyvale just sold for close to $800,000 over its listing price. Your eyes do not deceive you: The four-bed, two-bath house -- less than 2,000 square feet -- listed for $1,688,000 and sold for $2,470,000. "I think it's the most anything has ever gone for over asking in Sunnyvale -- a record for Sunnyvale," said Dave Clark, the Keller Williams agent who represented the sellers in the deal. "We anticipated it would go for $2 million, or over $2 million. But we had no idea it would ever go for what it went for." This kind of over-bidding is known to happen farther north in cities including Palo Alto, Los Altos and Mountain View. But as those places have grown far too expensive for most buyers, future homeowners have migrated south to Sunnyvale, a once modest community that now finds itself among the Bay Area's real estate hot spots.

- multiple HDMI can be obtained by connecting a separate HDMI switch box. Some even have remote controls

No. God no. You lost me at the first point. The last thing I need is another box and another remote.

I got cheap (< 10USD) HDMI switch box for my TV that doesn't require power and automatically detects signals and switches based on port priority. No remote, although you can get one if you want - there are also buttons on the box to force it to a specific input. I currently have my XBox360 and Steam Link plugged in, and maybe the rPi.
