    That would be useless, as the key could just be passed through.

    Critically, it also doesn't leave a trail by running a server anywhere.

    That's why they're using two different stats engines.

    They are linked as HTTP referrer, so they can get the tokens out of the stats page later on. It's using a popular and well known domain to evade detection.

    "Hey Siri" is.

    Siri recognises the "hey siri" bit unique to the owner, further commands aren't validated.

    The US military uses encrypted GPS, not the civilian one.

    I'm not really in this world, but you'd save more power by recycling aluminium cans (%5+ of US power consumption) than by killing off cryptocurrency mining.

    The answer is a little unfortunate, even though things are said to be worth $xxxxM market cap, but the depth of the market is so shallow that the true value is near zero.

    It's worthwhile to note that not a single once of the thousands of "ICO" things that have been launched in the last year have actually done anything of value. They all generate hyp…

    All obfuscation around a central controlling group that have the ability to reverse any transactions they don't like or negatively financially impact them, in other words.

    The principle of Ethereum is that code is law, the "hacker" followed the law to the letter and acted in a prescribed manner. What's the crime here exactly?

    If your concern is an attacker that can do 128 bits of work, you've got other problems (like reality).

    SHA3 is a hash function, not a KDF.

    There's beyond HDR, you can switch between multiple penetration levels and do automatic detection of materials even with ones made 2 decades ago. None of this is really new, insigh…

    In general yes, invisible things can burn your eyes but it's probably of no concern here. The more common thing you'll run into is things like cheap DPSS green lasers that output a…

    They are not opaque to X-Rays, much less the ludicrous penetrating power used in baggage inspection. Baggage X-rays can happily penetrate inches of metal, nothing short of lead bri…

    How does this handle SSH session re-keying, does that need further authentication from the device? openssh does this pretty infrequently, I can't immediately remember if that needs…

    So, capture the auth and use it for the malware, show the user some failure and allow their retry to pass. Stupid dodgy Yubikey fails half the time.

    No, luggage X-rays are extremely powerful, think 120kV or higher. They can easily penetrate inches of steel on the low end.
