Comment Re:is the USB 'bug' fixed, at this point? (Score 3) 77

I gave up on BBB and went to rpi because BBB couldn't come up with a distro that worked.

Got tired of dd'ing my SD storage space back to stock and starting over when the unit ceased to boot after installing another stock apt.

And that's assuming it even worked when clean which it didn't, at least not at first (I got one of the first batch).

Comment how many productions moved overseas? (Score 1) 131

The VFX workers may eventually have to come to grips with the idea that if you can't do it better you can't charge more for it. And thus they will probably have to cut their rates to compete.

This is basically the end game of the guild system Hollywood uses. You can keep people from undercutting you within the country by requiring guild membership and declaring union shops (or productions), but then the production just moves overseas. How many films are produced overseas nowadays to mitigate labor costs?

Comment 2012 Lincoln MKS, 2013 Cadillac CTS (Score 1) 155

Musk says AWD has never been put on a car with no loss of efficiency before.

2012 Lincoln MKS:
FWD version: 17/25 mpg.
AWD version: 17/25 mpg. And the AWD version is more powerful.

2013 Cadillac CTS:
RWD version: 18/27 mpg.
AWD version: 18/27 mpg. AWD version has same power (same engine) as RWD version.

So yes, AWD has been added without a loss of efficiency before.

Elon, it would be fantastic if you would bother to check to see if what you say is true before you say it.

Comment Re:"Must accept harmful interference..." (Score 1) 158

The issue isn't acceptance. The receiving devices are accepting the interference. The issue is the radiation:

b and c indicate what's going wrong here.

The system isn't emitting on 700MHz intentionally. It's just that the equipment is out of spec. Either it was designed wrong and the proper testing not done or else it was designed correctly and not built properly so the particular units that were installed in this building are out of spec.

Comment Re:The building owner is at fault? (Score 2) 158

The manufacturer of the ballasts already said they would replace them. But the building owners haven't taken advantage of this.

Devices of that sort (unintentional emitters) are subject to FCC regulations but do not go through FCC testing. They are generally self-certified. That is, the makers submits a document indicating they have tested the device and it conforms.

Comment cars do have dead reckoning (Score 1) 151

A GPS which receives speed, wheel position and reverse light data from the car does dead reckoning. I watched a friend's car do it just this weekend as we drove into an underground parking garage where you get no GPS reception.

Dead reckoning for car NAVs has been around forever, it actually predates GPS. The first in-car NAV systems by Etak were made using only maps and dead reckoning because GPS didn't exist yet. It also predated affordable LCD panels.

Before accelerometers and gyros were cheap Garmin even made add-on GPSes for cars which required installation so the NAV could get speedometer data and reverse light data so it could dead reckon your position.

Comment Re:Why not Aereo? (Score 1) 578

If you don't pay for satellite/cable you only get what goes out over the broadcast station. You can get that through Aereo. If you pay for cable/satellite and your cable/satellite kicks part of your bill on to NBC, then you also get the expanded coverage which includes live streaming of every event (not opening and closing ceremonies though).

So if you have Aereo, you still don't get what these people are complaining about not getting. Because you're not paying NBC. It is this kind of expanded content offering that the networks are using to justify monthly subscription fees (through your cable bill) when their over-the-air broadcasts are free to receive.

Some think that having part of their cable bill go to NBC whether they watch NBC or not isn't right. I can see the value of this argument. What I can't see is the value of an argument that if your money isn't going to NBC that they still owe you the expanded coverage just because this is an event you want to watch.

Comment Re:Move to Canada! (Score 1) 578

That chart is wrong. You can stream every event online live in the US. And you can replay stream any event which isn't going to be shown in primetime on replay immediately after it finishes.

Why do I care when the first live TV is shown when I already have streaming? I already watched the Slopestyle prelims online on day -1 on NBC's streams.

I do dislike that you can't watch some events on replay because they are held for primetime, but other than that, the coverage is great on NBC. If you want to watch it live, you can, assuming you are paying NBC through a cable/satellite subscription.

Comment you got it wrong too (Score 1) 476

The cable doesn't know anything about the battery state. The cable is a souped-up extension cord with some protection and detection. The charger in the car does the charging, it knows the battery state. The EVSE (the proper name of this cable) is not supposed to shut off when the current goes down, the charger in the car will take care of that.

The car has always stopped charging at full, since trickle charging a Li-Ion battery is a great way to put excess wear on it.

Tesla's EVSE may be cutting off due to power problems. While it may not be Tesla's fault specifically, this would be an issue Tesla has to address.
