Summary: Lots of improvements in a number of areas can make a big, big difference.

Since ~2008 I know they've increased the energy density of their 18650 cells by 20-30%, which would correspond to a 20-30% increase in range no matter what. After that it starts adding up quick.

I wonder if they might end up restarting roadster production. For a small car manufacturer that could even be fairly logical - produce as many as you can for a relatively short period of time(few years), then shut down production for a few years to let the demand recover and grow.

Perhaps more importantly, increasing the range of a car from 250 miles to ~400 also means that you could put a smaller battery pack in that costs nearly half as much, making it more affordable.

It also helps show the longevity of Battery Electronic Vehicles. Though it's only been two years since they stopped producing it, they're still producing not just maintenance parts, but serious upgrades.

So unless you were planning immolating yourself in front of Buckingham Palace as a protest for your country's policies, the quote is not really appropriate.

That would be an awfully odd place for me to do it, I'd be concerned that my message would be lost by doing it in a foreign country.

As for liberty/tyranny, it's always a balance that has to be constantly fought for. There's plenty of wannabe tyrants in the USA, UK, and pretty much every other country(including actual tyrants).

Having read your entire post, I'll say that I would have boiled down your post to what Free Censorship did. Well, I wouldn't mention North Korea.

"An attack on their dignity" - Mentioning the color blue is an attack on my dignity, you must never do that. Tying a noose is a reference to lynchings, even when you're a young boy from the north without a clue to that bit in history. Mentioning infidelity is an attack on the dignity of a politician.

Your dignity is a bit like the US 'right to seek happiness'. It doesn't mean that you can't be insulted.

Story I heard about mid-20th-century IBM mainframe. (I think it was the 360 series).

Core memory was tight and had cooling issues. The designers examined the instruction set and determined that, given cacheing and the like, no infinite loop could hammer a particular location more than one cycle in four (25% duty cycle), for which cooling was adequate. So they shipped.

Turns out, though, you could do a VERY LONG FINITE loop that hit a location every other cycle, for 50% duty cycle (not to mention the possibility of hitting a nearby location with some of the remaining cycles). Wasn't too long before a student managed to do this.

And set the core memory on fire.

And even if they were the same, I love how /. is so fixated on one mistake one department made over a decade ago.

How about the repeat three years ago?

And let's not forget about "OtherOS" four years ago.

Or profiteering from Whitney Houston's extremely convenient death two years ago.

No, Sony's PR problem doesn't come from "one mistake one department made over a decade ago", it comes from their entire corporate ethos, which their latest woes merely exemplify. They pretty much have made it a holiday tradition of shoving their foot up our asses on a yearly basis, and then expecting us to just smile and ask when the next gen of Playstation will come out so we can re-buy our entire game library that doesn't work on their empty promises of backward compatibility.

Well, as they say, the tree of liberty needs to occasionally be watered with the blood of tyrants and patriots. It appears that their tree is in need of some watering.

Besides that, top gear's Stephen Fry:
“It's now very common to hear people say, 'I'm rather offended by that.' As if that gives them certain rights. It's actually nothing more... than a whine. 'I find that offensive.' It has no meaning; it has no purpose; it has no reason to be respected as a phrase. 'I am offended by that.' Well, so fucking what."

And from Salman Rushdie:
“Nobody has the right to not be offended. That right doesn't exist in any declaration I have ever read.

If you are offended it is your problem, and frankly lots of things offend lots of people.

I can walk into a bookshop and point out a number of books that I find very unattractive in what they say. But it doesn't occur to me to burn the bookshop down. If you don't like a book, read another book. If you start reading a book and you decide you don't like it, nobody is telling you to finish it.

To read a 600-page novel and then say that it has deeply offended you: well, you have done a lot of work to be offended.”

There's a LOT of subjectivity in Olympic sports.

How about walk-racing? The rule is the walker must be in contact with the ground at all times....but slow motion video clearly shows they break the rule with every stride. So now they say "visible to the naked eye." And it's back in the hands of judges who, knowing full well that the walker is losing contact, have to decide if they can actually see it or just "know" it.
I guess the reason they don't fully enforce it that it would be even less interesting to watch.

US Internet Offers 10Gbps Fiber In Minneapolis 108

An anonymous reader writes Christmas came early in Minneapolis! U.S. Internet has announced that they are now offering 10 Gbps service to all of their existing fiber customers. Their prior top tier service was 1 Gbps. The article also goes on to state that they're actively working on rolling out 40 Gbps and 100 Gbps fiber service as well."
