Comment Dealerships are a facade (Score 4, Insightful) 261

They're really just repair shops who've applied with an auto manufacturer to become a local monopolist middle-man for a brand of automobiles and associated parts. They make the bulk of their money on repair work (in-warranty from the manufacturer and out-of-warranty on highly marked-up fees charged to consumers).

As far as I'm concerned, the sooner we move to a world where all cars can be purchased online direct, the better.

Comment Re: Solar panels are nice, but what about storage? (Score 5, Funny) 60

Well, one thought is that they could put the building on a huge hydraulic lift and in this way store solar energy as potential energy, then slowly drop the building to release that energy post-daylight. This has the added advantage of forcing workers to stay inside rolling lithium until the wee hours of the morning when, presumably, the floor reaches ground level.

Comment Re:remember everything that savings mean (Score 1) 183

Yeah I think everyone gets it, but don't you think you're being a bit overly dramatic about Amazon warehouse pickers? Think of all the paper shufflers personal computers put out to pasture 30 years ago. That had a much bigger impact than the few thousand seasonal warehouse pickers that will be impacted by this. Society will survive.

Ok I'll bite.

While I'm sure there is some truth to your assertions, why didn't one of the old industrials with the gray hairs running the show simply take their automated warehouse tech and dominate electronic retail so thoroughly? Were they just not greedy enough? I'm going to go out on a limb and assume that Amazon warehouses have subtly different requirements that required unique solutions.

Comment Re:1 billion batteries every ten years. (Score 3, Informative) 630

The primary constituents of lithium ion batteries are actually relatively straight forward to recycle (Lithium, Cobalt, Copper, Nickel, Graphite (carbon), Aluminum are the most common elements), and the batteries have useful lifetimes well beyond 10 years. However, the capacity degradation curve for Li-ion chemistries is mostly logarithmic, meaning even after it's done as an EV power store (say at 2/3s original capacity which might be reached after 10 years), it can last another 20+ years as grid storage, which doesn't require anywhere near the same weight/size to energy ratio.

Comment Re:Blinders Much (Score 4, Informative) 103

The main thing you need to remember is the focal length changes ... a 50mm lens on a 35mm camera is an objective lens which sees the world like you do. The same 50mm lens on a DSLR ends up being a moderate telephoto, and is equivalent to an 80mm lens.

That only applies if you have a crop sensor. Most professional DSLRs now are full frame.

Comment Ha. Let me explain why you're on this page... (Score 5, Informative) 398

It's because the media is a piece of fucking garbage and take practically every goddamn thing that's said by anyone out of context. Oh, and the folks who run Slashdot do effectively zero checking on anything they post. /rant

Now the explanation: Prior to the answer Musk gave indicating that Teslas would do 1000km on a charge, he was talking about a recently set record where a dude (Casey Spencer) did 500 miles (~800km) in a Tesla Model S, driving at something like 24mph for like 24 hours. In that context, Musk said that similarly, a 1000km could be achieved in a Tesla by 2017, given battery density improvements of 5-10% annually. All that would be necessary would be a 20% improvement on the record by 2017. I might add that the dude who did this was in a 85kWh car going downhill for a decent portion of the drive and took into account weather effects, temps and whatnot to achieve his 500 miles. I wouldn't be surprised if the latest 90kWh Model S as is could do another 100 miles if tightly controlled in the right conditions (high altitude, ideal temp/wind), so really a 5% improvement in both 2016 and 2017 is all that's really being predicted here.

Comment Am I the only one that sort of liked Flash? (Score 4, Interesting) 202

By having the majority of undesirable web content stuck in easy-to-flag Flash buckets, it was inherently simple to block that content. I could simply whitelist a handful of sites whose flash content I wanted to see (e.g. Youtube) and block it pretty much everywhere else.

Now with everything moving to HTML5, I fear the necessary blocking ruleset will gets many times more complicated and with more false positives and negatives to boot. Am I wrong?
