    Does the fetch happen immediately when Google receives the email? Or does it occur the first time the user opens the email? If the latter, sender image tracking will be alive and w…

    It may be trivially easy to host your own email, but in my experience it is nowhere as easy to do your own spam filtering. A few years ago when I ran my own mail server, having onl…

    Some JS engines already disallow security-violating operations from happening (such as inserting evil hooks into document.location). These same protections could apply to any Crypt…

    As eru said elsewhere, you've created a stream cipher. To be secure, the generated keystream (the thing you xor against the plaintext) must not have any biases: the attacker should…

    Ostensibly, a "a low-key ceremony in an actual beautiful natural area" (that can support 360 guests) would have a far greater ecological impact than manufacturing such a place in a…

    Aciicmez's BTB attack looks at the branch predictor, and is potentially valid against any implementation which branches based on sensitive data. There's a whole class of these atta…

    This article focuses pretty heavily on the possibility of cache timing attacks against AES, and cites djb's original work along with Tromer/Osvik's publication in 2005. Last week a…

    I'd be the first to tell you that I don't understand crypto. Most people don't. You're unwilling to have this conversation again; I understand. Do you have a link to one of your ta…

    It looks like you're being downvoted, so I'll provide a reason. Alcohol is legal. The gangs that formed around producing, smuggling, and selling alcohol (e.g. Capone) are gone. The…

    Don't forget about "Turbo Boost" - that "1.8 GHz" runs at 2.8 GHz when you're only using one of two cores. Combined with a more efficient architecture, this helps explain the perfo…

    I count 1930 applications, which is $357M in revenue, given the stated application fee of $185,000. This is three times the projected revenue of $92M [1]. It'll be interesting to s…

    You have a good point about TDD, and I'm unsure how to address it. However, you might find the itertools library helpful, particularly itertools.permutations(): http://docs.python.…
