  1. Re:Android first, maybe? on Google Drive Will Soon Back Up Your Entire Computer (theverge.com) · · Score: 2

    My android devices are currently backing themselves up to Google somehow, and I've restored the entire phone from backup with almost no problem. There were only a few apps I had that didn't support this, causing me to have to reconfigure them or transfer settings another way.

  4. Yahoo snatched defeat from jaws of victory on Yahoo Discussing Sale of Internet Business (bloomberg.com) · · Score: 1

    Yahoo games used to be one of the most popular places to play a ton of board game clones, but Yahoo snubbed mobile devices for years. What makes this extra mystifying is that almost all of their games were written in Java, and most mobile devices support Java. Why weren't they ported?

    History was recently repeated when several shows such as Community were purchased to promote Yahoo's video streaming service, "Yahoo Screen". But the apps and Chromecast support didn't exist until the season was almost over, and they were far from polished. Even the web interface is perplexing.

  6. Re:One small problem on What To Say When the Police Tell You To Stop Filming Them · · Score: 1

    From Radley Balko's excellent column at http://www.washingtonpost.com/... :

    When white people fled St. Louis in the early-to-mid-20th century, they took advantage of Missouri’s lenient incorporation laws to set up new towns to keep blacks away. As blacks began to move west, white people would move a little farther out, incorporate again, and set up new zoning laws to restrict black residency. The result is a county filled with dozens of tiny towns, nearly all of which have their own government and police force. The primary source of revenue for the local towns is sales tax. But the poorer (which means blacker) towns don’t generate enough income from sales taxes. So they turn to municipal fines to keep themselves from going under. The poorer the town and its residents, the more likely the town relies on fines for a greater percentage of its annual revenue. Which means that the blacker the town, the more likely its residents are getting treated like ATMs for the local government.

    The cops in these towns don’t deal with felony crimes. The county police investigate those. A local officer’s job is to administer fines. Most cops are drawn from whiter, wealthier areas, in part because so many people in the poorer areas have arrest records. That means you have cops patrolling areas they aren’t from who are charged with extracting fines from people with whom they have little in common, and for petty offenses.

    We did see a few examples of overt racism from city officials in the months after the Ferguson protests. But a system like this, one created by racism, will produce racist results even if none of the cops, prosecutors, or judges are racist themselves.

  7. Re:possible iOS Exploit? on Exploiting the DRAM Rowhammer Bug To Gain Kernel Privileges · · Score: 1

    Probably, and if you have physical access to the iPhone you can increase the rate of memory errors with mild heat. This paper from 2003 is pretty interesting and I'm not sure why it hasn't led to a new class of jailbreaking / rooting exploits yet. (That I'm aware of, at least.)
    http://sip.cs.princeton.edu/pr... :
    "Our attack works by sending to the JVM a Java program that is designed so that almost any memory error in its address space will allow it to take control of the JVM. All conventional Java and .NET virtual machines are vulnerable to this attack. The technique of the attack is broadly applicable against other language-based security schemes such as proof-carrying code.
    "We measured the attack on two commercial Java Virtual Machines: Sun’s and IBM’s. We show that a singlebit error in the Java program’s data space can be exploited to execute arbitrary code with a probability of about 70%, and multiple-bit errors with a lower probability.
    "Our attack is particularly relevant against smart cards or tamper-resistant computers, where the user has physical access (to the outside of the computer) and can use various means to induce faults; we have successfully used heat. Fortunately, there are some straightforward defenses against this attack."

  8. Re:Permenant Beta on Google Won't Enable Chrome Video Acceleration Because of Linux GPU Bugs · · Score: 1

    Google seems to be breaking (Youtube), abandoning (Google Voice), and outright eliminating/neutering (Google Reader, Google Shopping) a lot of its better products lately. The official corporate word is that this is "improving the experience" or "putting more wood behind fewer arrows", but it's more about internal turf wars (e.g. Vic Gundotra's Google Plus) and new engineers not wanting to merely maintain new code when they can make a name for themselves with something "new". Throw into this the fact that the average Google employee works there for 3 years.

    Maybe this all makes no difference to the average tech-ignorant user, but Google's flakiness is taking a toll on its reputation among anyone who pays attention. Ironically, most of this damage began when founder Larry Page took the reins, confident that he had finally learned how to CEO. Seems like he decided the way to do that is to emulate Facebook.

    So mind-numbingly wrong. Why do you think satellite dishes must be painstakingly aimed in the proper direction? Try listening through a parabolic amplifier (those dishes spies use) and see how quickly the volume drops off if you point it off the mark. You'd think more parabolas would show up in nature if they had the magical focus-making properties you think they do. I somewhat suspect you also meant your two ALWAYS assertions in a way that's mutually contradictory.

    Since the only case where a parabola fixes the focus is when the incoming rays are parallel to its axis (meaning the sun could only move toward and away from the face of the building), this makes the original poster's distance from being right more in the range of "hardly at all".

    In fact, rays that are not parallel to the axis don't even converge into a focal point:

    Nice about the RFC, but the ICMP problem shouldn't exist if both nodes send their packets out at approximately the exact same time. By the time each packet reaches the other side, the port should be open.

  24. Re:No other cross platform alternative... on Skype Encryption (Partly) Revealed · · Score: 1

    Using an intermediary is not the only way for two nodes behind separate NATs to talk to eachother: for UDP there's also a connection bootstrapping trick that gets them both hooked up. It works when the NAT doesn't rewrite the source port of a UDP packet, as is usually the case when a node uses an unoccupied source port (and as a random port is likely to be): each node simply starts sending a packet to the other node's source port. As the packet passes out through the NAT, it will remember that there is a "conversation" going on on that source/dest port pair and forward the incoming packets with the same port pair to the proper destination.

    This could work for TCP, also, if a node could generate a blind SYNACK with the correct sequence numbers and thereby cause the NAT to start forwarding - which is possible with the momentary assistance of an intermediary.

    Yes, this is a gross kludge and is inferior to proper NAT-traversal protocols like UPNP port forwarding, but it works in a large majority of real-world cases. Too bad it's not widely known or implemented.

    The conservation laws are *NOT* based on rigorous mathematics, but rather inference from observation.

    As to whether they are a "complete description", there is a major hurdle to overcome when defining "energy" on a subatomic level -- for one thing, because of the example of Maxwell's Demon http://en.wikipedia.org/wiki/Maxwell's_demon the definition must depend on the "information", which is an even less well-defined concept, although "conservation of information" has been posited as a law that seems to work well except around black holes.
