Comment Re:DTCP flag set on all channels (Score 1) 156

Depends on the carrier, and even from region to region. Some people would get everything but the premiums, some would get nothing. Even more annoying, broadcast TV had a copy protection flag in the spec, that was never implemented on broadcast receivers... except it shows up and is active on cablecard equipment, meaning you can be blocked from recording broadcast television.

I've not paid attention to this in several years, so it may be the whole industry has shifted to copy-once/never, which activates full DRM.

Comment Re:Make DRM work with my CableCard.... (Score 1) 156

Transmitting everything ClearQAM is stupid. They would have to structure their system so that no two packages used the same channel, and then install hardware filters for each subscriber at the pole. It would take weeks to get a tech out to change your subscription, and it would be a massive, pointless hardware overhead.

There's no problem with conditional access systems, and there's no problem with CableCard when it is used as a simple conditional access system. The tuner feeds encrypted data into the card, and the card feeds unencrypted data back to the system. No expensive hardware filters, easy management of subscriptions, free and clear access to everything you're paying for. Everyone is happy, except for the pirates wanting to steal cable, and the content providers who don't want subscribers to have free and clear access to their rightfully purchased content.

CableCard is only a problem when it actually invokes its DRM capabilities, and because of the expensive certification process it requires of authorized hardware to uphold its DRM capabilities.

publicly funded streets

Funded and built for a certain capacity and maintenance schedule. Side streets are not built for heavy traffic flow and they require more frequent maintenance if they are used that way. It's not just a homeowner issue - it's a city planning and infrastructure issue.

That's bullshit. Weather and heavy vehicle traffic are what cause roadway deterioration. A whole year's worth of car traffic on a residential street doesn't equal the damage done by a few passes of a plow truck, heavily loaded with brine that it's spewing onto the surface.

Comment Re:Artificial Gravity (Score 1) 154

The whole space station doesn't need to rotate in order to create artificial gravity. Just keep the living quarters in the rotating bit and the experiment areas in the none rotating bit.

It's not that simple. If you're rotating on a small radius, you're going to have a noticeable difference in apparent gravity between your feet and your head. Just as we don't know what long duration low gravity does to the human body, we don't know what long duration tidal gravity will do. If you're rotating on a large radius, well now you've got to construct this huge, high strength station. Now obviously, the only way we're ever going to find out is to throw something into orbit, and spend several years manning the thing, but the problem is a complex and not well understood one.

The hard part is probably trying to keep one area stationary while the other rotates. That's going to require something rotating in the opposite direction to cancel out any momentum.

Why do you have to cancel out any momentum? Why can the station not have a non-zero rotational momentum? Tons of satellites do.

Comment Re:Not likely to help diagnosis (Score 1) 119

If the MRI test falsely diagnoses children without autism as being autistic 20% of the time, then roughly 90% of all people who test positive will not be autistic.

According to the abstract, only 12% of those tested positive were not later diagnosed as autistic. You're just making argument over nonsense numbers, when the real numbers are available.
