It's unobservable to humans on a whole 'nother dimension anyways - duration. I don't think anything on this scale can change noticeably during our paltry lifetimes.
I would imagine one necessity of keeping track of who's who (i.e. authentication) is so people can receiving incoming calls and texts.
Since I am not crazy about the tracking aspect of cell phones, I would like if you could put them into a "stealth" mode where they don't exchange any information unless you initiate a call. You could whitelist certain places to sync up all your texts and emails opportunistically, like your home and office.
I realize you could already accomplish this by simply putting the phone in airplane mode all the time (well, I think so), but the whitelisting is the important part.
I think I see your point now, which is that taking advantage of the immediate proximity to the power source removes your choice of providers. Whereas you can fill up your gas tank at your choice of gas stations, there would only be a single power infrastructure built into the road, so, no choice. It's a good point. Although, electricity transmission losses aren't THAT bad, so if the company operating the solar panels by the road got too greedy, it would be cheaper to use electricity piped in from somewhere else. But I guess the wireless power transmitters in the road would have to be operated by a regulated power utility, with all the issues of that.
Well, that seems like asking who will pay for your data usage as you roll down the freeway streaming music to your cellphone. You will still buy the energy to power your car.
Even if it isn't terribly efficient, it could still mean that your car could charge almost anywhere you park it
Why park? If our freeways could power electric cars wirelessly, you could drive forever without stopping to recharge. Line the freeway median with solar panels, and the loss of wireless transmission is offset by minimizing losses through power lines and battery storage.
The subways in Seoul, Moscow, Beijing, Shanghai, and Tokyo together provide over 12 billion rides per year (cite). Tunneling is totally the way to go for dense transport. It's 3d, safe, efficient, relieves the open land of the blight of travel infrastructure, and the high initial cost of tunneling is super-amortized when ridden billions of times per year.
Actually it is idiots that keep all their savings in their own wallets, or in paper bag in the freezer, or buried in the yard. Whereas normal people do entrust their saving to complete strangers, all the time, in a thing called a "bank." This turns out to be much safer than holding it yourself, thanks to "regulations" enforced by "governments." Kind of impressive if you step back and think about it.
I doubt an honest-to-gosh end-to-end analog call has been placed in the US for decades; I think you are making the mistake of equating consumer VOIP with a real backend VOIP infrastructure with actual resources dedicated to it.
The consoles are evidently fill-rate limited, so framerate and pixel count are interchangeable. But sheesh, it's almost 2014, I want BOTH! If the games I would want aren't at least 30hz at 1080p, I'll pass.
You know, a 4k display only has 8 megapixels. It doesn't take a super-special camera to output 8 good megapixels. I'm no pro but my interests do exceed viewing people's cellphone snaps on their facebook pages, even if yours do not.
Another nice thing about OLED is the dark areas take no power. If I'm getting a 4K TV it will be a BIG one. But I don't want normal TV viewing to be that huge or power hungry, I want to light up just a 1080p area in the center, thus having a smaller TV inside my big TV.
I'm not the guy you want to ask that question, I have a linux PVR connected to my TV so I do use it as a computer sometimes.
I am disappointed the new Playstation 4 and XBox One won't support 4k gaming though. A 4-way head-to-head game (remember Goldeneye?) would be so cool on that. I wonder if any PC games would allow me to run two instances and 'network' them.
I set up suspend on a Thinkpad T400 lately and here are the main issues I recall:
Would not suspend if Flash was running in Firefox
Network would sometimes not resume correctly when using Wicd, or (separately) when using DHCP. This caused the NFS mount to hang, which effectively hangs the system.
Resuming from a keypress of an external keyboard required manual configuration of USB ports in BIOS and addition of udev rules.
Sound occasionally does not work after resume
X hangs occasionally when using the discrete Radeon graphics. (It was more reliable with the integrated graphics, but they're slow).
I think it depends largely on how much you stay on the beaten path. When you start using unusual peripherals, usage patterns, or OS settings, you tend to find bugs that the developers haven't heard many complaints about. Although that explanation doesn't seem to provide much cover for Tesla in this case.
I find this wrinkle hilarious, out of sympathy. I have never, EVER, in the course of using probably 10 laptops over the last 10 years, had one on which suspend/resume actually worked right. Many that worked a few times, or even a couple weeks, or that worked unless I used a docking station, or 3d acceleration, or WiFi. And yes, that includes my i7 MacBook Pro running OSX; plug and unplug the external display and network enough times, and sooner or later it will forget to wake up when you open the lid.
My beef here is the "cloud" aspect. I would only accept a device that I upload to my own computer at my own convenience.
I really hate how the "push" aspect of connectedness has developed... see also the WWW, Digital Video Recorders, and the new generation of game consoles. I guess I was naiive about the Internet to think this window on the world would be one-way.
I partially agree... there are some fields where a postdoc or two is mandatory, and thus not an indication that you're failing to launch. But then, yes, there are fields where a postdoc (or especially a second postdoc) means you're probably just holding out hope for too long.
Try to find people who exemplify whatever success you are seeking in your own field, and ask about their experiences. (Of course there's always a slim chance you'll break the mold...)
Slashdot Mirror
Which one? I'm using tightvncserver. I just tried it on the desktop natively and it did run.
X Error: BadShmSeg (invalid shared segment parameter) 128
unknown Extension: 129 (MIT-SHM)
So, it won't work on remote X, or VNC, or xpra, etc.

"Always" is a long time. Is there some reason a Picocell can't be produced for about the same cost as a WiFi access point?
Sure, because your cellphone is still associating with the nearest cell (i.e. tracking you) so that information can be pushed to you.
Since I am not crazy about the tracking aspect of cell phones, I would like if you could put them into a "stealth" mode where they don't exchange any information unless you initiate a call.

Well, that seems like asking who will pay for your data usage as you roll down the freeway streaming music to your cellphone. You will still buy the energy to power your car.
I agree, the power transmitters along the road would still have to be connected to the grid, since the solar would never exactly equal onsite demand.
Why park? If our freeways could power electric cars wirelessly, you could drive forever without stopping to recharge. Line the freeway median with solar panels, and the loss of wireless transmission is offset by minimizing losses through power lines and battery storage.

Your selective use of scare quotes is unfounded.

I can easily see pixellation on the 30" 2560x1600 monitor I'm sitting at. Please step aside and make way for progress.
1) Remove SD card from your digital camera.
2) Insert in SD slot on TV.
3) Enjoy.
