  1. Smart Talk? on AT&T Introducing Verizon-Style Shared Data Plans · · Score: 1

    Did you mean Straight Talk?

    Once my AT&T contract is over (maybe before - going to look into whether my ETF is prorated) I'm going to ST + unlocked phones (possibly the next Nexus now that Google is selling them on the Play Store.)

    Through my employer, I get 25% off of my plan and 50% off of my accessories, however:
    1) I still am spending $25/mo more on AT&T than I would on Straight Talk
    2) AT&T's phone selection sucks, and their software update policies have been atrocious. Every official update for the Galaxy S II was a horrific bugfest compared to the software available for the international version - even though getting I9100 firmware fully working on the I777 required only a weekend of kernel hacking for one guy (me).
    3) Because I am now using international unlocked devices, the 50% accesory discount is useless to me.

    Unless I can bring an unlocked phone WITHOUT paying a contract subsidy penalty by the end of my contract, I'm gone. Fuck you, AT&T.

    How is it bullshit? Did you bother to read what I wrote at all? What part of "It probably won't work with mixed vehicles at all - you don't get the speed/separation capacity benefits." didn't you understand?

    How many HOV lanes have you seen with curves designed for 50 mph?

  3. Re:No, it'll just be an OPTION on Will Speed Limits Inhibit Autonomous Car Adoption? · · Score: 4, Interesting

    One of the things that has been advertised as a big benefit for autonomous cars IS that much higher speeds are permissible while remaining safe. Similarly, much closer following distances are possible without compromising safety.

    Many of our speed limits are based on safety decisions made based on "typical" human reaction times. You can get a ticket now for "following too closely" based on the assumption that at speed X, you need Y feet of separation to be safe based on a reaction time of N milliseconds.

    The reaction time of an autonomous vehicle is far less than N milliseconts, permitting X to be higher and Y much lower.

    There have been, for example, "auto trains" of multiple autonomous vehicles operating with ridiculously small separation distances on test tracks.

    The problem is - how do you make the transition? A mix of autonomous and human-driven vehicles won't work well unless the autonomous vehicles obey the limits imposed on human-driven vehicles. So you need to segregate the human vehicles from the autonomous ones. This is really difficult in most places.

    There's one exception: In many metropolitan areas, highways have HOV lanes. HOV lanes are intended to increase the capacity (in humans per hour) of that lane. In quite a few areas, they have the secondary goal of reducing fuel consumption and emissions per user. (In some places, this goal has been prioritized to the point where vehicles that meet certain emissions/efficiency standards are permitted in HOV lanes with fewer occupants than the normal HOV limit - http://en.wikipedia.org/wiki/High-occupancy_vehicle_lane#Qualifying_vehicles.)

    A big problem with current HOV lanes is, honestly, the humans. On quite a few business trips to Long Island, my coworkers and I met the HOV lane criteria during a time the HOV lane restrictions were enforced (usually the tail end/beginning end of that period when traffic was lighter than the peaks the HOV lane was designed for). In quite a few cases, there were enough HOV-eligible vehicles that the HOV lanes weren't any faster than the main lanes. In a few cases, a single vehicle meeting HOV eligibility but with a slow driver would render the HOV lane significantly slower than the non-HOV lanes of the highway.

    Autonomous vehicles would be the perfect solution to the remaining HOV lane problems. Most likely, the cost of autonomous vehicles will mean that the costs of them meeting above-average emissions/efficiency standards won't be that much more. (After all, Google's "open road" driverless vehicle is a Prius, which meets the "single occupant in HOV lane exception" requirements in many areas that have such exceptions for "green" vehicles.) - Autonomous vehicles can achieve significantly higher speeds at lower separations in a HOV lane, significantly increasing the lane's capacity significantly even for single-occupant vehicles.

    The problem is, of course - the transition. Making a HOV lane into an autonomous-only lane requires enough autonomous vehicles to justify it. It probably won't work with mixed vehicles at all - you don't get the speed/separation capacity benefits.

    Yeah. "Sandbox" apps like this will be received better by employees. If you try OS-level encryption with policy enforcements (such as Exchange policy enforcements), users will find ways to bypass the policy enforcements that get in the way of "normal personal operations" and this will also kill the security of the things you want to keep secure.

    Sandboxes like Good for Enterprise don't annoy users when they are engaged in personal use, so they are far less likely to disable security measures.

    Even for those situations listed above where you could tether to a smartphone, extremely low data caps (you'd kill your data allowance on most carriers with a single 720p movie for example) mean that cloud storage of video is nowhere near ready for mobile devices, and even cloud storage of music is a bad idea.

  8. Re:Google support of third party mods on Google Releases Android 4.1 Source Code · · Score: 3, Insightful

    Wrong. It's pretty clear that the carriers are the major blocker for updates.

    For example, the Samsung Infuse 4G was originally released with Android 2.2. Canadian devices on Rogers received Gingerbread (Android 2.3) in late July/early August 2011. AT&T devices did not see Gingerbread until February 2012.

    The Samsung Captivate was nearly identical to the original Samsung Galaxy S. The similarities were enough that community developers were able to have the I9000 Gingerbread release fully functional within weeks of Gingerbread for the I9000 becoming available. The Captivate did not receive an official upgrade through AT&T for NINE MONTHS.

    The AT&T variant of the Samsung Galaxy S II (SGH-I777) is nearly identical to the international version (GT-I9100). As a result, there are only a handful of software differences required between the two handsets:
    1) Change the digital I/O settings for the audio chip to a different sample rate - this was included in the GT-I9100 source code release
    2) Change the keymap for the touchkeys - This was also included in the GT-I9100 source code release
    3) Unmap the GPIO line for the HOME key which doesn't exist on the device - This was missing from the GT-I9100 source code release, but took less than a week to identify and fix
    4) Swap the audio channels for the noise cancelling and main microphones - This took me a single Saturday to reverse engineer and fix

    Despite these minor changes, the AT&T ICS release was delayed for more than three months, and was of worse quality than some of the early I9100 ICS leak builds. In addition to poor battery performance, frequent crashes, and other bugs not present in the initial I9100 ICS release, the SGH-I777 official release contains a severe bug that can permanently damage the device's eMMC storage if the user performs a factory reset.

    If carriers didn't get in the way, the SGH-I777 would not exist - users would have received the GT-I9100 and would have received a high-quality ICS build in mid-March instead of an awful hackjob in late June.

    For that thing to be unsafe you'd have to jam the antenna up your ass. At this point, there are plenty of "unsafe" things going on even if the RF is off, such as having a metal object jammed up your ass. :)

    Key aspects of safety around pulsed transmitters that have very high peak power but moderate average power:
    1) Don't walk through the fucking beam! (Although I know of an engineer that determined he would be within OSHA limits if he kept exposure to 30 seconds per 6 minutes at a range of 20+ feet occasionally...)
    2) Humans don't arc. Shit that will instantly sizzlefry electronics will do nothing to a human if it's a low duty cycle pulse.

    Another way to read this is: Duty cycle is very important when dealing with human safety. So that leads to the question: What is the transmit power of these smart meters? What is the duty cycle? The article claiming they are "unsafe" has zero data on these crucial parameters.

    2) Most such aircraft also have a fairly robust inertial navigation system the GPS is checked against. (often this is checked as part of the RAIM monitoring process)
    3) In the case of manned aircraft not on an instrument approach, you need to defeat the Mk1 Eyeball in addition to the GPS and INS.
    4) In the case of manned aircraft on instrument approach - most airports still also have legacy ILS.

    In short - spoofing a civilian aircraft without causing a "my instruments are fucked, pull up" pilot response is orders of magnitude more difficult than this hack.

    In addition, there's absolutely no evidence to back this claim - "But the big worry is — it also means that it wouldn't be too hard for [a very skilled person] to work out how to un-encrypt military drones and spoof them, and that could be extremely dangerous because they could turn them on the wrong people."

    Transitioning from "making a few fake pseudolites" to "discovering the crypto key before it changes" (I believe the keys rotate on a daily basis, so you would need to crack the key AND the key change algorithm) is a MAJOR step. I don't know what universe that person lives in if they thing breaking military-grade crypto is even remotely close to this attack in complexity. This attack is easymode compared to generating a proper P(Y) code.

    The only "break" so far in the military encryption is the fact that the same keys (and in fact same signal) are used on both L1 and L2, allowing you to cross-correlate L1 and L2 to determine ionospheric delay and remove that one error source. Note that the next block of GPS satellites adds a civilian L2 signal, so this "break" is mostly irrelevant.

    In addition, no evidence was provided that a RAIM-enabled receiver was successfully spoofed, only a cheap consumer-grade unit that lacked RAIM.
