The comment threshold slider is completely broken on multi-touch devices. You can't "click and drag" in any modern multi-touch browser (iPhone, Android, Touchpad, Playbook, etc.) If you try, it just pans the page. "Touch and drag" is the universal pan / scroll gesture.
They mentioned the temperatures in the live video. I don't recall the exact numbers, but the range did peak at ~15C in sunlight. They also mentioned that the water was likely salty, and that this would push down the freezing temperature. Moreover, the phenomena is seasonal, and I think the runoff occurs in the martian summer.
They spent 12.9B on a poor quality military communications satellite, and yet they want to cancel the James Webb space telescope because its projected cost rose to 6.8B!?! Our priorities are all wrong!
Bug bounties are paid once. Meanwhile, there are many black hats who may be willing to pay for an exploit package, access to bot nets, etc. I imagine there is more money to be made using bugs for nefarious purposes.
