Submission + - Watch celestial mechanics in (almost) real time! (io9.com)

wisebabo writes: If Sir Isaac Newton weren't already dead and in Heaven, I'm sure this would make him die and go there.

Here (scroll down to the GIF, please) is a time-lapse sequence taken by Cassini at Saturn of a small (okay tiny) moon "Prometheus" pulling out streamers of dust from the nearby ring over and over again. For eternity. (Or at least tens of millions of years). While the sequence only shows one such event, a quick glance at a larger scale (scroll to the top, please) shows that it is doing so repeatedly. L i k e c l o c k w o r k.

Despite all the troubles in the world (although the number of deaths due to war DO seem to be decreasing which is a minor problem in itself http://www.nytimes.com/2014/06...) these kind of things make me realize that I am living in an incredible age.

Submission + - This Is How Formula 1 Brakes Work

cartechboy writes: For the most part, you probably have a simple understanding of how your car's brakes work. But a race car, that's a whole different beast. Brembo's the biggest name in the brake industry, and it just released a video explaining the technology that goes into the brakes on a Formula 1 race car from pedal to caliper. Obviously it starts with every component being beefed up from a normal braking system, but there's also aluminum monoblock calipers, carbon rotors and pads, a brake-by-wire system with a redundancy in case of an electronic failure, and a kinetic energy recovery system (KERS). Of course, KERS is the most interesting bit as the it allows for smaller rear calipers than before which of course reduces mass. Believe it or not, all of this stuff ends up trickling down to mass-market cars eventually, it's just a matter of time. So the next time you tap your brakes, remember, that technology was likely proven on a race car at some point.

Submission + - Interviews: Ask "The King of Kong" Billy Mitchell About Classic Video Games

samzenpus writes: Billy Mitchell owns the Rickey's World Famous Restaurant chain, sells his own line of hot sauces, and was called, "probably the greatest arcade-video-game player of all time". His was the first to achieve a perfect score in Pac-Man, and held many record scores in other arcade games. He is probably most famous for the 2007 documentary,"The King of Kong: A Fistful of Quarters". The film follows a challenger on his quest to surpass Billy's high score in Donkey Kong, which Mitchell had set in 1982. Since the film was made, the Kong crown has been held by a number people including twice by Mitchell. Billy has agreed to put down the quarters and answer any questions you might have. As usual, ask as many as you'd like, but please, one question per post.

Submission + - FCC Demands States to get out of the way of municipal broadband (engadget.com)

RavenLrD20k writes: I hope that Mr. Wheeler has the ability and the stones to actually act on this, but I'm not holding my breath. From the article:

While his recent waffling on Net Neutrality is still cause for concern, Tom Wheeler's recent statements in support of municipal broadband are worth cheering. In a statement posted to the FCC site, Wheeler said that: "If the people, acting through their elected local governments, want to pursue competitive community broadband, they shouldn't be stopped by state laws promoted by cable and telephone companies that don't want that competition."

That's about as strong a statement as one can expect from the head of a regulatory body. Plus, it's a pretty blunt challenge to both the industry he once lobbied on behalf of, and the government officials many believe are in their back pockets. In particular he cited the case of Chattanooga, TN which built out its own gigabit per-second fiber network out of frustration with the options offered by the incumbent Comcast. The trouble is, Tennessee's state government passed a law restricting municipal broadband projects...


Submission + - DOT Aims to Regulate Map Aids in Vehicles (nytimes.com)

schwit1 writes: The US Department of Transportation is intensifying its battle against distracted driving by seeking explicit authority from Congress to regulate navigation aids of all types, including apps on smartphones.

The measure, included in the Obama administration’s proposed transportation bill, would specify that the National Highway Traffic Safety Administration has the authority to set restrictions on the apps and later order changes if they are deemed dangerous, much the way it currently regulates mechanical features of cars.

The measure has the support of automakers, which already mostly comply with voluntary guidelines for built-in navigation systems, but it has run into stiff opposition from technology companies, which say that any such law would be impractical and impossible to enforce. It’s another example, they say, of federal regulators trying vainly to keep up with a rapidly changing industry.

Submission + - LinkedIn spam lawsuit can continue (pcworld.com)

Submission + - Need to move to IPv6 highlighted as Microsoft runs out of US address space (networkworld.com)

alphadogg writes: Microsoft has been forced to start using its global stock of IPv4 addresses to keep its Azure cloud service afloat in the U.S., highlighting the growing importance of making the shift to IP version 6. The newer version of the Internet Protocol adds an almost inexhaustible number of addresses thanks to a 128-bit long address field, compared to the 32 bits used by version 4. The IPv4 address space has been fully assigned in the U.S., meaning there are no additional addresses available, Microsoft said in a blog post earlier this week. http://blog.azure.com/2014/06/... This requires the company to use the IPv4 address space available to it globally for new services, it said.

Do you seriously want to have apps that seem to hang for 2-5 seconds every time a button is pushed just because it needs to save its state before it enters a new one? Most phone apps do not do anything where they need to have their state saved from one moment to the next. The only times you want to have an app continuously saving a file is if it's editing a local document of some kind. If you do happen to have an app that needs to keep persistent data from instance to instance, that's what the OnPause() or OnStop() methods are for. Then this data can be loaded back in when the app regains foreground by using the onResume() method, or regains visibility by using the onRestart() method.

Seriously, read up on the Activity Life Cycle so you can begin to understand what you're talking about.

My post was about what happens when the Phone App takes over. In my development experience, when the phone App takes over, the apps don't always get to perform the OnPause() or even the OnStop() methods before they go straight to OnDestroy(). Having the app actively listening for the phone call event (which occurs about 2 seconds before the phone system activates the phone Application) will give your app an extra bit of time to get the app state saved and properly stopped before the memory manager starts performing an aggressive cleanup to make room for the phone App (this is especially true on low end phones that don't have a substantial amount of application memory to work with).

In fairness, while Location is completely optional and generally unnecessary unless the app is designed for the user to make use of the location data, it is generally a good practice for apps to watch for phone calls just so if there's one that comes in while you're performing $(menial computation X), the app state can be saved to storage and the app suspended so if Dalvik decides it needs to free up the memory resources in the middle of your call there's still a way for the app to recover where it was in its calculations. The reason you want your app monitoring the phone system instead of trusting that OnPause() is going to get called when a phone call comes in is simply that you cannot trust that the Phone App will not cause Dalvik to simply destroy the app instance without allowing calls to OnPause() or even OnStop(). This is especially true on lower end phones that don't necessarily have the memory to spare to run apps in the background when the phone, a memory hog in itself, activates.

I have no problem with having a HUD on glasses. As a biker I could think of many uses of such (a HUD on my visor would be very nice for reading speed/gear/tach/general status without looking down at my gauges, as well as nav). My question is, why does it need a mounted camera too? As a biker, I could make use of a camera rear mounted on my helmet to use as a wide angle rear view. I could also make use of a wide angle feed coming off my front fender to get a different perspective on the road. But to have a feed coming from a camera mounted right beside my own eyeball would be roughly useless. When you need augmented reality or facial recognition or such, sure, attach a camera to the rim; but take the bloody thing off when it's not necessary for what you do.

It's all a matter of taste and what we can relate to. I've not been able to get into any of the Gold Age stories that I've found, and the Silver Age still tends to have too much camp. Being a child of the 80's and teen of the 90's I guess it makes sense that my tastes tend to travel along the trenches of the Bronze and Modern ages.

Have you tried asking your partner what she'd recommend? You don't seem to have the experience with comics to realize it, but your question is extremely loaded. There are so many threads from the Golden Age that you could start reading about and reading through a particular thread and it may wind up having no relevance to what your lady likes. Is she into Dick Tracy? Classic Superman, WonderWoman or Batman? Submariner? Human Torch (not to be confused with Johnny Storm from Fantastic 4)? If you talk with your partner about what she likes from that era, she may be willing to open up to you more and start to take you under her wing.

On the other hand... if she looks at you with a highbrow "you're not worthy" sort of look and seems to be annoyed with you learning this world, she may want to keep this world to herself for her own private enjoyment.

Just as much as if the admin password was "toor", "god","dog","password", or "openSesame". A hack is still a hack even if it doesn't require a high level of skill. The skill required to successfully pull off a hack (and not get caught) only contributes to the degree of warm fuzzies a hacker would feel. It does not change the fact that it is a hack.
