  1. Re:Beyond 404 HiJacking on Sony Leaks Reveal Hollywood Is Trying To Break DNS · · Score: 1

    It's not really 404 hijacking, it's DNS resolution failure hijacking. If you get a 404, then you at least got to the site. Anyway, DNS hijacking is why I don't use my ISP's DNS.

  2. Re:Backups are not secure on Backblaze's 6 TB Hard Drive Face-Off · · Score: 1

    This is really not a good approach to using public key crypto. The private key shouldn't be on the servers, it should be on the client. I know it's a pain to handle per-file backups and especially deltas when everything is encrypted, but that's the tradeoff for proper security. In fact there's really no need for expensive public key crypto here at all. Just have the client use a cheapish symmetric key (AES256 perhaps) and send only encrypted data to the servers. There's no need at all for the servers to ever have the data in the clear.

    You could punch a hole to turn a double-density floppy into a high density floppy, at least with the 3.5" floppies. It worked the few times I tried it but the need for antics like that faded pretty quickly as technology marched on.

    From what information the police have released since then, it looks like you're right on the mark. The guy is a violent nutjob that also happens to be an Iranian Muslem; and he has lived in Australia for almost 20 years now. I doubt he has much connection with Islamic State beyond their chat boards.

    It's really the same mechanism. In one case the high energy rays impart enough energy to charge or drain a gate, and in another high energy rays impart enough energy to break a DNA bond. The parent was talking about being continually hit with enough high energy rays to instantly crash a normal computer, which is well above the amount you need to kill a person.

    After the patch my box started complaining endlessly that it was not genuine windows, but when I went to activate Windows page it said I was already activated and just told me all of the great benefits of having genuine Windows and that I should install MS Defender.

    It non-activated dialog box wanted me to install some application to double activate it or something? I've had a tough time figuring out exactly what's up with it. The links all point to genuine microsoft.com websites, so it doesn't appear to be malware, but I'll be damned if it's not acting like malware.

  10. Re:And the #1 option is... on 3D Printer Owner's Network Puts Together Buyer's Guide · · Score: 1

    The big reason for the huge price drops in the past couple of years is a whole bunch of the patents expiring. At this point the primary limitations to making them cheaper are technical, not legal. This means we shouldn't expect to see the same magnitude of price reduction going forward that we've seen in the recent past. The only area where I expect to see significant movement is on the filament, which still strikes me as overpriced for what it is. It's only a matter of time till some factory in China is spitting that stuff out by the ton and undercutting everybody.

  13. Re:XBMC Finally? on $35 Quad-core Hacker SBC Offers Raspberry Pi-like Size and I/O · · Score: 1

    It doesn't help that the Raspberry Pi foundation finally released an update after 2 years...and left the specs almost completely unchanged. Not even a badly needed speed bump on the CPU or an ARM architecture update that makes it less of a pain in the butt to support. Not even a RAM bump, even though many many apps (XBMC included) bump into the RAM limit on the Pi constantly, severely degrading its performance.

    The situation is so ridiculous that overclocking is officially supported on their default distro (Raspbian) in the installer. It really helps too. Even a little 300Mhz clock bump makes the Pi feel twice as fast (mostly from the increased clock on the RAM). Unfortunately, in my experience the built-in "turbo" mode is generally over aggressive with the Core and GPU and you'll eventually get crashes when doing 3D games or hitting the USB controller (and remember, the networking on the box is all USB).

    For what it is worth, if you have Samsung memory (Hynix sucks), I've had good success across several Pis with the following config:
    arm_freq=1000
    sdram_freq=600
    core_freq=400
    gpu_freq=333
    avoid_pwm_pll=1
    over_voltage=6

    This setup plays Quake3 smoothly (mostly) at 1280x1024 and runs Chromium reasonably well if you don't have too much other stuff open (beware hitting the memory limit though, swapping on the Pi makes it nigh unusable--no more than 2 or 3 tabs open at once). Another caveat: The analog audio will be crackly with this config, use HDMI audio or remove the "avoid_pwm_pll" line and reduce core_freq to 333 to match the gpu_freq. I don't have any of the B+s to try it out, but given the extra couple of years they've had I expect them to overclock even better than the old model Bs. If you are one of those poor suckers with a Hynix Pi, you are probably going to have to remove the sdram_freq line as well, it just doesn't overclock for beans.

  14. Re:XBMC Finally? on $35 Quad-core Hacker SBC Offers Raspberry Pi-like Size and I/O · · Score: 1

    The Pi is actually surprisingly good at streaming video, but with a big list of caveats. The biggest is that it is only good at streaming 2 (3 if you pay a little extra money) formats. Luckily one of them is mp4 so it's not a complete disaster, but anything it can't do on the GPU is too slow to be useable. XBMC's interface is also a poor choice for the Pi, as it is not GPU accelerated on the Pi and quite slow as a result.

    The Broadcom chip on the Pi is really designed to stream video. The CPU is almost an afterthought, and is mostly there to service the USB controller and feed data into the GPU.

  15. Re:Why wasn't this already revoked? on New Destover Malware Signed By Stolen Sony Certificate · · Score: 1

    Because CRLs suck and using them is a last resort. Plus, Sony has to re-issue the certs first or it will break existing consumer equipment. There is a chicken and egg problem where you want to push down the new certs securely before you invalidate the old ones, otherwise the consumers will get a warning about an improperly signed server trying to mess with the security on their machine.

    Or they have to wait for some third party (Windows Update for instance) to push it out, which takes time.

    I'm more worried that a laser powerful enough to evaporate a wet leaf in a fraction of a second is going to reflect off of the rails at other times, burning parallel lines in the roofs of tunnels, potentially burning holes in people who just happen to be walking over a crossbridge at the wrong time, or blinding pilots.
