  1. Bystander Data? on New Cellphone Surveillance Safeguards Imposed On Federal Law Enforcement · · Score: 1

    Why does the bystander data need to be destroyed unless it was collected as allowed by the warrant? Are they issuing warrants to collect bystander data? What probable cause allows that?

  2. Re:Trust on system updates broken on Microsoft's Telemetry Additions To Windows 7 and 8 Raise Privacy Concerns · · Score: 1

    The thing that worries me it that there are now dozens of articles about which updates to remove to disable telemetry or the Windows 10 update nagbox. We've been saying that installing security updates is fundamental to keeping your computer secure. This goes against that. Do we really want to teach people to uninstall random updates based on shady blog articles?

    Earlier I had all automatic update checkboxes checked, because I trusted that security updates are just that - security updates. From now on I'll be checking all the updates manually before installing, and I really hate to have to do that.

    The real question is did MIcrosoft want to teach that because they have.

  3. Re:Beamfromin and MIMO isn't magic... on Ask Slashdot: Can Any Wireless Tech Challenge Fiber To the Home? · · Score: 1

    It's also wrong in an ideal world, as the number and placement of antennas dictates the geometries over which beams can be steered, including the minimum spacing between a beam of desired energy and a null of undesired radiation. (Same logic appears on Rx...) More antennas is more cost, but also has fundamental need for more bandwidth dedicated to training the BF/MIMO weights.

    It is actually worse than this.

    The beam steering in this case is done after demodulation on receive so an interfering source is present through each receiver, digitized, and then subtracted.

    Direct conversion WiFi receivers already suffer from poor dynamic range and this will not help when strong interfering signals are present.

    The best place for the access point is not likely to be the best place for the switch so the lack of multiple LAN ports does not bother me. My Nanostation also only has 1 LAN port although it was not really intended for use as a WiFi/WAN/LAN router.

    The privacy destroying aspects and lack of local configuration make it a deal-killer for me.

    The congestion is further into AT&T's network. My local FTTN connection is perfect other than having a power backup time of seconds or less in the event of loss of power. My side is backed up but the DSLAM or something further into the network is not.

    These days it is not even that. For more than a year now my U-Verse FTTN service has suffered from congestion during peak times with peak times being more than 1/3rd of the day and congestion yielding download speeds (upload not affected) below 1 Mb with attendant packet loss. I responded by downgrading my service to the slowest service they provide since anything faster is not usable.

    The latency (and various mysterious failures like suddenly being unable to pass HTTP but not other protocols) still make me long for the days of SDSL.

    Should be an interesting test of the Supreme court. As I understand the Roe V Wade decision had some pretty similar arguments. A lot of it came down to an issue of standing and it was determined that, while by normal standings rules, a person denied an abortion would not have standing to bring a case until injured, but if a pregnancy was life threatening, that would be an effective denial of right to sue.

  13. Responsibility? on A "Public Health" Approach To Internet of Things Security · · Score: 1

    Bray says unless you plan to unplug from the Internet completely, every consumer needs to assume some responsibility for the security and overall health of the Internet of Everything.

    This is not going to be reasonable or even possible when devices are using obfuscated or poorly documented protocols which is becoming more prevalent. The best that the consumer will be able to do is isolate every device from every other (with a VLAN switch or equivalent) and block all incoming connections.

    For example with Windows 10 or Windows 7 and later with various updates, how is the consumer to know via traffic inspection what is normal expected traffic and what is not? Even if you shut off all of the privacy destroying features, Windows still generates traffic. How do you distinguish this traffic from other malicious traffic?

    Yes, and it felt fine. They didn't stop me, so I simply drove comfortably below the speed limit. A bit boring, but nothing to worry about. If you want to get rid of them, go even slower and they will pass.

    I was once honest to gawd pulled over for going exactly the speed limit. It was in a neighborhood where most people speed through, so I guess the officer found someone obeying the speed limit mighty suspicious.

    A compiled list of reasons allowing reasonable suspicion to pull someone over in Texas included traveling slower than the speed limit, traveling at the speed limit, and traveling faster than the speed limit.

  15. Re:Why so complicated? on Why Modular Smartphones Are Such a Nightmare To Develop · · Score: 1

    It is not that difficult. The only issue is transmission line stub length.

    Use current mode low voltage differential signaling to keep the power down with a termination at either end of the transmission line. Then every transmitter in the middle sees the transmission line impedance divided by 2 because it is driving two transmission line in parallel. The transmitters at the ends see the same transmission line impedance divided by 2 because they are driving a transmission line and an immediately adjacent termination although the termination may be placed remotely.

    Receivers are high impedance just like on the old Ethernet 10Base-2 standard.

    If the minimum stub length is too long for the baud rate because of integrated circuit packaging and layout, then use the same trick Tektronix used on fast oscilloscopes by using 4 pins instead of 2 pins and route the transmission line on and off of the integrated circuit so the stub length is only on the integrated circuit.

  16. Re:The cars can detect gestures. on When Should Cops Be Allowed To Take Control of Self-Driving Cars? · · Score: 1

    Absolutely correct. Officers are (normally) trained that they need to allow the person to travel to a location they feel safe, which can mean a lit area or a populated area. Similarly if you are are on a bridge or somewhere with no shoulder, you can turn on your hazard lights, slow down, and continue to a safe area. If someone in the vehicle has a cell phone, they can call 911, describe the situation, and tell dispatch they will stop in a location with light and other people. You can also call 911 to verify the person is a real officer.

    They may be trained in this but most officers (and the court) will use your not stopping immediately as evidence against you.

  17. Re:Exceeds state authority on California Bill Would Dramatically Limit Commercial Drones · · Score: 1

    The FAA must rely on the grant of power in Art 1 Sec 8 of the constitution to regulate commerce among the several states.

    Airliners bound for other states fly over my house every day. I concede the FAA's authority over those airplanes and their flights.

    OTOH, a little drone flying barely above the treetops has a far slimmer case to be part of interstate commerce.

    Federal jurisdiction over use of the air is not unlimited, and cannot be used to displace state jurisdiction on non commercial uses of airspace in realms that are clearly not part of the commercial airways.

    The hook for being relevant to interstate commerce may be as small as "has moved in or that otherwise affects interstate or foreign commerce". I am sure some part or parts of the drone will not have been indigenous to California.

    I personally guess that California's right to regulate the use of airspace below 500 feet outside of airport landing zones is constitutional and will be upheld if the law is enacted.

    I agree insofar as the California law does not conflict with any federal law.

    These days a T1 is painfully slow, even without multiple or even a single other user. I can't think of any reason to still use a dedicated circuit like that unless you absolutely positively need the guaranteed bandwidth and SLA service...or there was absolutely no other option.

    Or you want lower latency. My U-Verse service using FTTN has 3 to 4 times the latency to the gateway than my old SDSL had and the SDSL upload speed was half of the current U-Verse speed so it was not that much slower. Upload bandwidth has doubled but latency has increased 4 times.

    This puts business users who run Win10 at significant legal risk, given that they knew (or should have known) that every Win10 machine contains a general-purpose mechanism pre-installed that allows a third-party attacker (Microsoft) to silently collect any information at will.

    Sure, the firewall part has been done using a Raspberry Pi. Because of the limitations of using one or more additional USB to ethernet converters, the speed and perhaps reliability is not anything to write home about but it is fast enough for most US internet connections.

    Better I think would be to use embedded x86 hardware like from Netgate to run pfsense. Maybe a pfsense plug-in will be produced to handle the Microsoft security violations.

    The write protect jumpers were originally used because Flash memory at the time required an external high voltage supply for programming and the cheapest way to control this was through a physical jumper.

    I agree that controlling this through hardware is a good idea. The programming supply is no longer available for this but the write protect jumper could block the write strobe instead. Unfortunately some newer Flash memories do not have a separate write strobe either.

    Couple points, that decision was flawed. It is well documented that it was one of the worse Supreme Court cases in history. And likely staged...Neither the defendants nor their legal counsel appeared at the Supreme Court. A lack of financial support and procedural irregularities prevented counsel from traveling.[4] Miller was found shot to death in April, before the decision was rendered.[5]

    So imagine using as precedent a case that was never even defended against. So what were the precedents established?

    1.The Second Amendment protects only the ownership of military-type weapons appropriate for use in an organized militia.

    2.The "double barrel 12-gauge Stevens shotgun having a barrel less than 18 inches in length, bearing identification number 76230" was never used in any militia organization.

    The situation with Miller is even worse than this:

    The Peculiar Story of United States v. Miller

    2. Our military now regularly uses short barreled shotguns in door-to-door operations. As such, short barreled rifles would now have to be legal sans the tax stamp.

    And even back in the day it was an incorrect decisions as: During WWI, between 30,000 and 40,000 short-barreled pump-action shotguns were purchased by the US Ordnance Department and saw service in the trenches and for guarding German prisoners.

    Radiation damage to integrated electronics in satellites was a big problem at the time, and I'm not sure why that's different now, but in any case they decided to use core memory rather than chip memory. (hence the term "core dump" for all you youngsters).

    The simplest integrated processes use junction isolation which is susceptible to all kind of additional problems when exposed to radiation compared to integrated circuits which use dielectric isolation.
