Yeah, the TV was state of the art when I got it, replaced a 34" CRT. Since then I'm boycotting Sony because of the Sony_BMG_copy_protection_rootkit_scandal. Every now and then they come out with something really nice that I would otherwise be tempted to buy, but I don't because of that dick move they did. They deserved to go out of business at the time, and I'm still hoping they will.

I must have bought that TV back around 2003 - at the time a good plasma would have cost at least $10,000, would have been 780p instead of 1080p, and would have been thicker and used a lot more power. So, at the time it seemed like a good tradeoff even if the black level left a lot to be desired.

Comment Re:Cold weather? (Score 1) 198

What happens then? Does cold weather affect battery performance? Without an internal combustion engine, the only way to get heat in the cabin is via electricity, which is going to impose a considerable burden on the battery.

Not really...Consider this, if the battery is powerful enough to drive the car around for miles then powering a little heater and fan isn't going to tax it that much. I'm driving my Nissan LEAF in Pennsylvania in 20 degree F weather this week and I drove it all through last winter too. There is an ~10-20% hit to the range in colder weather, but the heater [and my heated steering wheel] isn't that big of deal, certainly no more than running the AC in the summer. It gets along just fine. In fact, last winter I jumped my wife's Honda Accord car with my LEAF when her battery died on a very cold morning... in that regard, EVs are more reliable to at least start in the cold.

I drive a Honda Fit EV and have a slightly different experience. In cold weather (it's been around 0 here in Boston the last few days) I lose about 50% of my range if I don't use the electric cabin heater. I attribute this to:

1) Denser air increasing aerodynamic drag (happens to ICE cars as well)
2) Can't charge the battery to the full 19kwh

Later versions of the Leaf use a heat pump rather than just a resistive cabin heater, so that may explain why your Leaf does better than my Fit. I believe the Tesla uses heat from either the battery pack or electric motor to help warm the cabin - I'm sure a Tesla person will jump in and correct me.

My point is that a compliance car like the Fit EV (so, I'm curious about the Bolt) can take a huge hit if you try to keep the cabin warm. I find that I lose about 1 mile per khw if I keep the cabin at about 65F, my daughter tends to keep it 70-75F when she's driving around town, and that can eat up another mile/kwh...

My only purpose for posting is that this is something that EV manufacturers need to keep in mind - seems like Tesla may have done the best job of this, Nissan addressed it a couple years into production, and some compliance cars don't do anything special and it can make them much less useful during winter months in northern states.

and then I bought a 4K LED backlit LCD with full dimming

I'm waiting for the OLED price to drop a bit (and hope that any kinks get worked out), but the reason I don't want to replace my old shitty-contrast LED TV is that the local dimming ones bother me - in lots of images I see the local dimming effect as an artifact, and it drives me crazy. I'll see a scene where it's apparent and suddenly I'm no longer watching the movie, I'm looking at the screen for more artifacts.

Am I the only one this bothers?

To be fair the "article" does mention Sony's OLED TVs

Not really replying to what you said just responding to the "Sony" part; I currently have a ~12 year old Sony, and they make some good stuff, but when they did the root kit thing in 2005 I swore I would never buy another piece of Sony gear, and I'm sticking with that... They deserved to go out of business over that snafu, so I'll just keep buying stuff from their competition and hope they eventually go out of business.


Comment Re:But we got a TV in 2015 (Score 1) 238

Not surprising that you might not notice. Question is, would a photographer/graphic designer/architect/interior designer/ etc. notice? Certainly as a part time photographer I notice it a lot!

The other thing is that people are amazingly good at getting used to crap. Many years ago when TVs were all CRTs I was visiting a friend. There was clearly a problem with his TV because the image was very very green. I asked him about it and he didn't know what I was talking about. He had gotten used to it and saw it as "normal". I couldn't believe that he didn't see how screwed up the picture was.

There are clearly changes which are very subtle that the average person won't notice. 4K is probably an example of that, except in very large screens. If you walk an average person into a room with an LED set, and then walk them into a room with an OLED set, yeah, lots of them won't notice, whereas if you show them side by side they probably will notice. It really is a huge difference in image quality, so just because you're used to LED crap, doesn't mean that OLED isn't a big improvement...

Would I pay $4K right now? No, especially because the light output is lower than LED and my screen is in a bright room. But when it hits $2K for a 65 or 70 inch screen, I'll probably upgrade from my LED.

It is a larger change from the Plasma -> LCD switch that happened years ago.

People changed from plasma to LCD? Not me - plasma looks great. LCD looks washed out and can't display black.

So, isn't that exactly the point? OLED gets you most of the visual improvements of Plasma without some of the drawbacks (power, depth).

But it's an incremental upgrade in quality. Clearly most people don't care much about color fidelity, or LCD never would have taken off. Compared to plasma, OLED has some incremental advantages, mostly lower power consumption.

Well, in addition to power consumption, how about price, weight and depth? (and, knowing people, it was probably mostly price).

One remaining problem with OLED is light output. I think it's about 1/2 of a LED display. It's an issue for some people: my tv is in a room that's a wall of glass... so, even the LED is pretty unwatchable during certain hours of the day, which is fine: I only watch it at night so it works out okay, but lots of people probably value the light output over the darker blacks.

Personally, I paid $5K for an early Sony Bravia LED and the black level is pretty horrible, so I've been waiting for OLED, mostly for the prices to drop but also for the technology to become more mature. This might be the year that I pull the trigger.

Yeah.... you are a genius for making this comparison. Nothing has changed in 100 years to make ramping up a car company easier.

Not sure if you're implying that it's easier now to ramp up a car company? I would have guessed the opposite: lots more governmental regulations to meet now. You obviously couldn't bring a Model T car to market today - it would fail on so many fronts it would be crazy to try. Also, people's expectations of even a basic car are pretty high now. No electric start? No air conditioning? No AM/FM/BT/SAT/USB entertainment system? People have pretty high expectations even for a basic car.

Additionally, when the Model T was introduced, there was a huge market of first time buyers available (most people didn't have cars). Now, not so much...

It's interesting that you do not deny that Putin's interest in relieving the economic sanctions trumps (pun intended) his interest in crushing Isis. Ok. We are in agreement there.

You seem like a bright fellow, so you'll probably recognize the fallacy you've presented in your own post regarding Podesta's lobbying firm taking money from a Russian bank. Did that money actually win them influence over Hillary Clinton? Apparently not. According to your prolific tirades against Clinton on Slashdot, she's a war mongering hawk trying to start wars with Russia. Donald Trump, in contrast, has the potential to (using your words)--

...join hands with Russia and Turkey to crush Isis.

You are trying to paint Clinton and Podesta as puppets of Russian lobbying money, while claiming the DNC also promotes Putin as a boogeyman. Kind of emphasizes the lack of real influence this money had on Clinton. You repeatedly reference this Saudi oil money going to the Clinton Foundation and paying for Chelsea's wedding, but where are the details on the quid pro quo? What was gained for them or the Russian bank?

I think we're getting tired of your broken record of "yeah, but Clinton collected money from xyz." Why don't you build up a stronger case for why Trump should hold hands with Putin to destroy Isis? We would all like to see your references to the great and wonderful things Vladimir Putin has done that would help explain how his involvement in Syria is only out of a humanitarian interest. I am very curious to hear more about your rationale for Donald Trump developing closer relations with Vladimir Putin.

..instead of having the US join hands with Russia and Turkey to crush Isis.

The Russian interest at play here is not to crush Isis, but to crush the economic sanctions against Russia for invading Crimea and trying to take over Ukraine. These sanctions are crippling the ability of the Russian Oligarchy to enjoy their wealth and amass more.

Do you think Paul Manafort was advising Trump on how Russia could join hands to help the US destroy ISIS, or do you think he was telling Trump about how all the Russian oligarchs would love him if he were to remove these annoying sanctions?

Trump has a track record of championing making money over punishing wrong-doers. Consider this episode where he wanted a convicted rapist to avoid prison time so his casino could profit off of his boxing match--

Trump and Tyson are old friends who did business together in the late 1980s, when the real estate mogul promoted and hosted several of Tyson's fights at his Atlantic City casinos and even fashioned himself for a time as the boxer's "business adviser." And in a largely forgotten episode, Trump came to the boxer's aid during one the darkest moments of Tyson's careerâ"his 1992 conviction for raping a beauty queen. To save the champ from being locked up, Trump pitched a highly controversial proposal that would have essentially allowed Tyson to buy his way out of prison.

Your premise in denouncing the report is that the methodology employed is not as sophisticated as you expect Russia to be capable of. You should consider and acknowledge a couple of espionage realities:

The spearphishing employed against Podesta worked and was trackable. The report is not going to talk about the hacking attempts that did not work and were not trackable. As in the case of the Tempest vans you reference. Because the report does not mention Tempest vans does not mean they are not driving around.

Intelligence agencies will only release info that does not compromise their capabilities of collecting intelligence. If they were to release a transcript of a private office conversation between Putin and Paul Manafort containing details of the hacking, then Putin would realize there is a bug in his office and clear it out. The confidence of these US intelligence agencies that Russia was meddling in the recent election is buttressed by information collected that can't be released without divulging the source mechanism for its collection. What you see in the report is safe information to release.

Carnival get's the leftovers, who will complain when poked. There are very few talented people working there for long.

Well, that may be true, but I wonder whether it's because of the qualifications of the staff, or whether the environment sucks so bad that the good people leave after a short stay. If so, that's the company selecting for poor employees.

I'm not IT, but any modern company who treats it as mere overhead does so at their own peril. Remember back in June when SouthWest had computer issues? "Flight delays across our network have resulted in 600-700 canceled and delayed flights". That cost the airline a lot of money and hassle.

Then you think about companies being hacked... you can literally bankrupt the company if you are hacked big time.

Does every IT department need to be all A-Team people? No, and in fact people like that might end up being bored in some shops. But a good solid team that can be depended on for reliable uptime and quick reaction when stuff does go wrong? Seems pretty important to me.

And offshoring like Carnival is doing? Why would you want to put the fate of the company in some external company that you have no control over day-to-day? Yeah, great, you can fire them when a major IT problem hurts you, and you might even be able to recover some of the losses in a lawsuit, but me, I'd much rather put together a solid team of people who have loyalty to the company and can be depended upon to do a good solid job.
