Astronomers Get Picture of Nearby Exoplanet
The Bad Astronomer writes "While nearly a thousand planets are known to orbit other stars, getting direct pictures of them is extremely difficult due to the glare from their host stars. Fewer than a dozen images of exoplanets exist. However, we can now add one more to the list: Kappa Andromedae b, or Kap And b for short. It's about 170 light years away, and orbits Kappa And, a massive star bright enough to see with the naked eye. One hitch: its mass puts it right at the upper limit for a planet, and it may edge into brown dwarf territory. Further observations are needed to pin its mass down." -
iPhone 5 GeekBench Results
EGSonikku writes "The iPhone 5 has been benchmarked using the GeekBench tool. According to the results, Apple's claim of 2x higher performance over the iPhone 4S seems accurate. The results show the iPhone 5's A6 CPU is dual core and clocked at 1.2GHz, and is paired with 1GB of RAM. Despite the fact that the Samsung Galaxy S3 has a quad core CPU at 1.4GHz, and twice as much RAM, it seems the iPhone 5 is faster than the S3, or any other Android handset." Meanwhile, Samsung has launched a marketing campaign that compares some of the hardware specs and features between the new iPhone 5 and the GS3. -
Two Space Missions Planned To Look For Killer Asteroids
The Bad Astronomer writes "Today, the B612 Foundation announced it's seeking private funds to build Sentinel, a space mission to find Earth-threatening asteroids. Placed in a Venus-like orbit, it should find a large fraction of these potentially hazardous rocks. At the same time, the NEOCam (Near Earth Object camera) website went live today. This is a separate, publicly-funded space mission also designed to look for these asteroids. While Sentinel will concentrate on finding them and getting accurate positions and orbits, NEOCam will focus more on getting their physical characteristics. While not strictly competing with each other, they are more complementary; with both missions flying (in the 2017 time range) we will learn a huge amount about the asteroid threat from space." -
Stellar Blast Boils Away Some of a Planet's Atmosphere
The Bad Astronomer writes "Using a combination of Hubble and Swift observations, astronomers have apparently witnessed some of a planet's atmosphere being peeled away by a powerful stellar blast. HD 189733b orbits its star just 4 million km from the surface, and a few hours after Swift detected a big X-ray flare from the star, Hubble data revealed a big jump in hydrogen absorption as the planet transited the star. This indicates the planet's atmosphere was blasted off by the flare to the tune of a thousand tons of hydrogen per second. The planet is so hot it probably already loses a substantial amount of air to space all the time, but this spike is the first time a change in an exoplanet's atmosphere has been detected." -
Are 'Real Names' Policies an Abuse of Power?
telekon writes "Microsoft researcher Danah Boyd argues in this article that 'The people who most heavily rely on pseudonyms in online spaces are those who are most marginalized by systems of power.' This comes in the wake of criticism aimed at Facebook and Google for their stance on anonymity and pseudonymity. A related article from the Atlantic discusses how revolutionary the real name requirement really is." -
Ubuntu Will Switch To Base-10 File Size Units In Future Release
CyberDragon777 writes "Ubuntu's future 10.10 operating system is going to make a small, but contentious change to how file sizes are represented. Like most other operating systems using binary prefixes, Ubuntu currently represents 1 kB (kilobyte) as 1024 bytes (base-2). But starting with 10.10, a switch to SI prefixes (base-10) will denote 1 kB as 1000 bytes, 1 MB as 1000 kB, 1 GB as 1000 MB, and so on." -
Jobs and Gates Chat Amicably
circletimessquare writes "As noted, Bill Gates and Steve Jobs met at the D conference yesterday. AllThingsD has video of the entire convivial and historic meeting — check the highlights clip. When a reporter asked if their rivalry was overblown, Jobs offered up this joke: 'We've kept our marriage secret for over a decade' — to an apparently flummoxed Gates. Other tidbits: 'His mother loves him!' said Gates about PC Guy in the famous series of commercials. 'And we love them because they're all customers!' said Jobs about Microsoft employees working on Zune who use the iPod. Read more about the event, which also covered a lot of serious ground, such as Apple's iPhone, at CNN and the Times Online." -
Old Islamic Tile Patterns Show Modern Math Insight
arbitraryaardvark writes "Reuters reports that medieval Muslims made a mega math marvel. Tile patterns on middle eastern mosques display a kind of quasicrystalline effect that was unknown in the west until rediscovered by Penrose in the 1970s. 'Quasicrystalline patterns comprise a set of interlocking units whose pattern never repeats, even when extended infinitely in all directions, and possess a special form of symmetry.' It isn't known if the mosque designers understood the math behind the patterns or not." -
Facebook Scrambles after Unexpected Privacy Fumble
bart_scriv writes "Facebook is responding to the recent uproar among its users by deploying better privacy protections and control, as well as being more open about future changes. This could be a case study for other social networking sites on how to avoid or deal with similar problems in the future." From the article: "A week before launch, when asked if he was concerned about a privacy backlash, he appeared surprised, saying, 'No, these people share stuff already and they get something out of sharing.' They've shared all right. And Facebook is listening. On Sept. 7, the site is ratcheting up privacy protections--the result of around-the-clock coding. On their privacy settings page, people will be given greater control over what items will or won't be included in news feeds." Relatedly, an anonymous reader writes "A recent Reuters article mentions that Facebook user Igor Hiller, 17, a freshman at University of California, Santa Barbara is organizing a real-world demonstration next Monday at Facebook's downtown Palo Alto headquarters." Read below for Zuckerman's Open Letter to the community. theStorminMormon writes ""We really messed this one up." begins an open letter from Mark Zuckerberg to the Facebook community. The letter goes on to say: "When we launched News Feed and Mini-Feed we were trying to provide you with a stream of information about your social world. Instead, we did a bad job of explaining what the new features were and an even worse job of giving you control of them. I'd like to try to correct those errors now.
When I made Facebook two years ago my goal was to help people understand what was going on in their world a little better. I wanted to create an environment where people could share whatever information they wanted, but also have control over whom they shared that information with. I think a lot of the success we've seen is because of these basic principles.
We made the site so that all of our members are a part of smaller networks like schools, companies or regions, so you can only see the profiles of people who are in your networks and your friends. We did this to make sure you could share information with the people you care about. This is the same reason we have built extensive privacy settings — to give you even more control over who you share your information with.
Somehow we missed this point with Feed and we didn't build in the proper privacy controls right away. This was a big mistake on our part, and I'm sorry for it. But apologizing isn't enough. I wanted to make sure we did something about it, and quickly. So we have been coding nonstop for two days to get you better privacy controls. This new privacy page will allow you to choose which types of stories go into your Mini-Feed and your friends' News Feeds, and it also lists the type of actions Facebook will never let any other person know about. If you have more comments, please send them over.
This may sound silly, but I want to thank all of you who have written in and created groups and protested. Even though I wish I hadn't made so many of you angry, I am glad we got to hear you. And I am also glad that News Feed highlighted all these groups so people could find them and share their opinions with each other as well.
About a week ago I created a group called Free Flow of Information on the Internet, because that's what I believe in — helping people share information with the people they want to share it with. I'd encourage you to check it out to learn more about what guides those of us who make Facebook. Tomorrow at 4pm est, I will be in that group with a bunch of people from Facebook, and we would love to discuss all of this with you. It would be great to see you there.
Thanks for taking the time to read this,

Christie's Auction House gets Star Trek Props
circletimessquare writes "A New York Times reporter was granted access to the trove of 40 years of Star Trek props that Christie's, the auction house, is cataloguing for auction in October. 'The stuff of "Star Trek' — uniforms, communicators and other props, including pointy rubber ears — has boldly gone to a place where the intrepid crew never took the Enterprise: the Bronx.' For an opening bid of $1,000 to $1,500, you can own an original tribble. 'It's an Auction, Jim, but Not as We Know It.'" -
Novell To Open Source SUSE
jambarama writes "Newsforge reports Novell will be open sourcing SUSE professional under the name OpenSUSE. Is Novell following in the footsteps of Red Hat Inc., with its Fedora Core Linux distribution, or continuing its own open source policy as it has in the past as with YAST?" Note that it looks like the opensuse.org site is not yet up. -
Suggestions for Performing Regression Testing?
gmletzkojr asks: "The company that I am currently working at develops a fairly complex industrial controller, complete with embedded software, a GUI on the controller, and a Windows app to connect over Ethernet. On previous versions of a similar project, we have performed testing manually - ie, monkey presses button, and sees that light turns on, widget turns, GUI updates, etc. However, this is extremely time consuming (previous complete regression testing took ~3 weeks) and is error prone in itself. How do you perform complete system regression testing? Do you use shrink-wrapped packages, or build your own? How do you test features that are easy for humans to observe, but not as easy for software to detect (ie, the light came on, the GUI updated when I pressed the external input, etc)?"
