    Not really. Every country that has weapons development also has export controls. It isn't about believing your government is moral or good. Its about understanding that your govern…

    Not really. Military grade weapons are a big deal. They're used to kill people. Export controls are there to prevent killing machines getting in the hands of a countries enemies (o…

    If you support export controls for security reasons, this is kind of inevitable. The government shouldn't be forced to buy any type of military technology someone creates. But even…

    There's nothing unlibertarian about a private business making up its own terms of services and privately enforcing them. That's exactly how the free market self regulates without t…

    Twitter isn't sinking. It just isn't ascending as fast as investors would like to ensure hyper growth. While its always great for your career to be in a company that's constantly g…

    Not sure DDOS clauses are that unreasonable. Especially when attackers might be targeting your DNS server, even though you're the target.

    This often happens when I'm travelling internationally. If I plan on buying a local sim card instead of purchasing a roaming plan - I might not have access to my SMS until I get ba…

    Great point. "correct horse battery staple" wouldn't be vulnerable to such an attack.

    Mistakes were made, and there are definitely lessons to be learned, but if we want to improve the state of security, we really need to change the way we react to these types of bug…

    More likely along the lines of if ((isset($_POST["SecurityQuestion0"]) && $_POST["SecurityQuestion0"] != $answer0) || (isset($_POST["SecurityQuestion1"]) && $_POST["SecurityQuestio…

    If you're breaking your contract, that's something to be enforced by your landlord and the courts. Not something you need special laws to forbid.

    Based on the "you can still rent a bedroom" comments, I'm guessing the people commenting here are single and definitely don't have kids.

    Is it really a Chicken and egg situation? SF prices in the last years have skyrocketed, through out the city. The financial incentive to build is there. But there isn't massive bui…

    Subways make sense in dense urban areas - When a lot of people are within walking distance from the subway station. For SF to justify extensive subway infrastructure, it needs to s…

    Which part do you consider an opening act of a cold war? Launching a cyber attack in a foreign country - or arresting someone who launched a cyber attack?

    The weakest link I can identify here is MITM attacks when you're sending the link. Imagine: Alice generates a link. Sends the link to Bob over an unencrypted/unauthenticated link. …

    Comparing political candidates to Hitler is a rather lazy thought experiment.

    I agree with the first part, it's kind of a self reinforcing decision. Intel wanted INT 3 to be for break points so they gave it a single byte instruction, and because INT 3 is a s…

    What's even better is that breakpoints haven't really changed over that period of time. They just work. While a lot of tech is rapidly moving and constantly changing - this is the …

    Comment #12732296

    The reason INT 3 is used is that it's the only interrupt that has a single byte opcode (0xCC). Other interrupts require two bytes: CD . This makes setting a breakpoint really easy,…
