    The Justice Department filed an action fighting robocalls today. This particular case is interesting for several reasons, and we can learn a lot from it. (Thread)

    Security folks - do you know where I can get access to daily historical data of Alexa's top 1 million? (e.g., say I want daily snapshots of the top 1 million in April of 2016)

    The aviation GPS/ADS-B failure right now is interesting. So far only affects some aircraft, which suggest it's not an over-the-air jamming issue. Sounds like a client side software/configuration problem, but hard to be definitive.

    Great conference, great community, and great location! Looking forward to listening to the talks at Oh, and having an excuse to go back home to Miami, drink a colada, and eat amazing Hispanic food is always a plus :)

    Multiple Boeing 787s in China experienced GPS 20 years rollover issue. Some aircrafts have to be grounded waiting for an update.

    Amazing article! A Ph.D. has ups and downs all the time. "Sometimes it’s best to take a deep breath, do your best to tackle the challenge, and—in the meantime—appreciate that you’re doing something you love."

    Teachers! Parents! It is legal and perfectly welcome to email scientists asking for a PDF of their paper. Until all papers are free, please RT to make this more widely known. And fyi, scientists don't get the $$ from sales of papers so all it costs us is 1 minute of time!

    There's likely much more information here. Check out our 2016 paper "Sending Out an SMS: Characterizing the Security of the SMS Ecosystem with Public Gateways" for a deeper look at the kind of data such a leak may provide.
