You know those storage bags that you suck the air out of with a vacuum so they take up less space? Imagine putting a sponge in one, and sucking out all the air. It would end up flat as a pancake, which is probably the same way a bag of areogel would look under those conditions.
I don't have one, but basically summarizing from the CNET review, the problems are the exact same problems I see with any cheap, no-name tablet:
* Poor display (very limited viewing angle, washed out colors). * Poor battery life (2 hours gaming, 4 hours watching video, 8 hours on standby doing nothing at all). * Poorly designed physical controls. D-Pad consisting of 4 individual buttons was the worst the reviewer had ever seen on any gaming device. Analog sticks are stiff.
The battery and the display are what sets apart the premium devices from the cheap ones, and that's how they get the price down. This device appears to be no exception.
When a board member calls up the CEO and says that it's unanimous, it's time for you to leave, the CEO can either save face and "resign", or let the board officially vote them out. Regardless of what they're calling it, "fired" is probably an accurate description.
The difference you're talking about over the course of a single hour is negligible. What I said is accurate in the real-world, measurable sense. We'd be talking about only 1 or 2 degrees K. If this was over the course of several hours, then yes, the cooling would slow down as the room's temperature approaches the outside temperature. But that's not what I, or the article, is talking about, is it?
Turning off air conditioning or heat for one hour will accomplish absolutely nothing. As soon as it is turned back on it still has to move or generate all the heat energy over that hour it would have otherwise. Simply put, it will have to work a little harder to catch up what it would have been doing over that hour anyway. Same with hot water heaters, dehumidifiers, refrigerators, etc. Merely putting off washing clothes, cooking, etc obviously accomplishes nothing either.
Board to engineer: We're excited to see the first demonstration of our new 3D printer! Let's see what you've got... Engineer to board: I've got good news and not so good news. The good news is the printer is working great, and I've brought several printed objects for you to take a look at. Board member: What's the bad news? Production costs are higher than estimated? Engineer: Well, not really. We have a scale problem. Unfortunately, the intern that exported the CAD blueprints to the machinists wasn't used to the software, and the exported design was 1/10th the scale it should have been. We didn't notice the problem until the molds were already created to mass produce the printer. Board members look at one another in alarm and begin murmuring to one another. Engineer: However, there's an upside - we can now make really tiny things with ten times the precision! It's a "NANO" printer! You will find sample objects already located on the center of the table. I just hope no one has sneezed. Board members lean forward, squinting and looking at various objects the size of grains of salt. Board member: Oh, that's what those things are. I was about to have the cleaning lady fired. Engineer: I hope this doesn't mean we lose or bonus? We did meet the deadline after all. Board member, picks up something off the table, then holding fingers together next to his head, rubs them back and forth. Engineer: What's that supposed to mean? Board member: I'm just playing the world's smallest violin, which just happened to have been printed on our newest 3D printer.
Why did you fixate on only the lighting part of this story? Of course those two things you chose to comment on are widely used. What type of lighting would you think they'd use?
What about power generation using not one, or two, but three different forms of renewable energy? These walmarts you speak of. Are they generating enough power to be a zero power use facility too?
Further, Raspberry Pis cannot act as a slave USB device, only a host (it is a hardware limitation in the way the chipset was physically connected to the USB port - required components for USB slave are not in place). Thus USB could not be the physical connectivity in a dock. The only other option would be to use the GPIO pins directly to try and emulate the OEM's proprietary dock connector, however I very much doubt the pi could communicate at a high enough rate to communicate with the laptop. The bandwidth of the dock port would have to be very high to support USB, LAN, etc, all in parallel.
It would be far easier to take a stock dock and embed a USB flash drive in it hardwired to one of the existing ports. Then if autorun is still enabled on the laptop the payload would be executed.
When the electron was discovered, it could have also, and naively been considered useless.
I don't really agree with that. The effects and usefulness of the electron - aka electricity - were "discovered" before anyone knew what the electron was. It was already useful before the exact mechanism (the electron) was even understood. The practical came long before the theory and the full understanding of the physics.
The watch replaces your phone. I assume you carry a phone pretty much all the time, correct? Now you won't be carrying a phone. You'll be wearing a watch. The battery lasts for days, and you already go to the trouble of charging it and keeping up with it because you use it for so many other things.
So in your scenario, right now, you have a phone you have to charge and carry around, and if you wanted to read ebooks on an actual eink screen, you would then have to buy an ebook reader, which you'd also have to charge and carry around. Further, you would have to get the books onto your ebook reader. For a $40 "chi-co" reader you're surely not going to have even wifi, let alone 3G, so that means you need yet another device - a laptop or PC - to act as USB host to download ebooks and upload them to your reader.
In my scenario, you already have your watch with you, and it has mobile data, thus it is always connected to the internet already. You want to read a book? You pull it up on your watch. That screen is too small? You grab an eInk display and your watch pushes data to it. That requires absolutely no extra power from your watch, as it is simply idle 99% of the time, and sending a page worth of text to another device is trivial extra load. In fact, it would be power-saving, because you're not even using the display on your watch to read, thus it doesn't have to power that up.
The architecture of this device is just slightly ahead of its time. It is, literally, a secondary display for a primary computing device. Electronic ink is optimal for reading when there is enough ambient light, so it would be much better than reading a book on a cell phone (plus the screen size is larger too). However, there are two places where this would be the killer app, and neither are mainstream yet: Google Glasses, and the iWatch. Both of those are wearable computers, but they both have sub-optimal displays. That's where an external display would be extremely useful. It would make a whole lot of sense to just extend your existing wearable computer into an ebook reader, instead of having to carry (and thus synchronize / manage data / etc) a discreet device.
Imagine - you have your Txtr in your hand, or simply propped up on a little stand or laying on your lap as you read. To turn the page, you just give your wrist (the one your iWatch is on) a little flick, and the page turns. Pretty much optimal.
This really is the future. Your iWatch or Google Glasses will be your primary computing device for everything. Want to watch a movie at home? It simply outputs wirelessly to your TV (with an Apple TV box attached). Want to browse the internet? Use an external display that looks like an iPad, but that is merely a display and touchscreen. Want to read an ebook? Grab an eInk screen. Got a lot of typing to do? Whip out your bluetooth keyboard. I predict devices in a laptop form factor (including touch screen) that is nothing more than an I/O device for your wearable computer.
I tend to agree that some sort of nuclear response would be required. The word "nuclear" must somehow be involved in at least one of the weapons launched in retaliation. The reason? Iran will be watching.
The problem is that he's using his fame achieved from his art to gain a larger audience for his message. That's when it's time to start to actively deny him his fame.
Tell that to Lady Gaga, and Madonna, and all the other liberal celebrities pushing their pesonal agenda, and flat out telling people who to vote for. Do you really think Obama could have been elected without 3/4th of the news and media outlets trying as hard as they possibly could to get him elected? And the same for far more than 3/4th of the movie stars and musicians?
Somehow various viewpoints and agendas in the United States have managed to be spun in such a way as to imply "if you are against this then you are full of hate". Just because someone doesn't agree that marriage should be redefined as a union between two people of the same sex does not mean they hate people that are homosexual. However at this time, that is the label now automatically applied to anyone who disagrees with that viewpoint.
I uninstalled everything starting with "java" on my computers, and the only thing now missing is the every-other-day notification that Java needs to be updated.
No, you are totally incorrect. Humphreys spoofed a commercial, civilian drone, using the unencrypted civilian GPS channel. The military uses a private GPS channel that is secure and encrypted and has not been hacked or spoofed. In addition, the newest GPS satellites modulate the signal in such a way (called M-code) as to further prevent spoofing (the edges of the square waveforms are peaks with troughs in the middle of the waveform, making it harder to overlay one signal onto another, so the receiver is actually looking at the shape of the waveform and not just the raw digital data it encodes by each peak and trough- or something like that).
Humphreys: Sure. Well GPS spoofing takes advantage of the fact that the civilian GPS signals, as you mentioned, are unencrypted and unauthenticated; so, whereas the military GPS signals have an encryption code overlaid on them, the civilian ones do not and never have.
We did so by purchasing our own drone. No one would lend us a drone because they knew it was going to be a risky endeavor and we generated fictitious GPS signals, captured the drone and brought it down.
"Hacking a UAV by GPS spoofing is but one expression of a larger problem: insecure civil GPS technology has over the last two decades been absorbed deeply into critical systems within our national infrastructure," Humphries told the subcommittee in his testimony. "Besides UAVs, civil GPS spoofing also presents a danger to manned aircraft, maritime craft, communications systems, banking and finance institutions, and the national power grid."
What he demonstrated has absolutely nothing to do with military at all. He's raising awareness to the risks of controlling important, life-or-death type hardware with unsecured civilian GPS.
I'm undoing my negative moderation of your post to reply to your comment. In case you don't understand the context of this video, it is the final lap of the race. Everyone is excited because it is a close race with a number of cars vying for the win. Perhaps you don't enjoy watching sports, or rooting for a particular person or team to win, but most people tend to get rather excited when a long competition comes down to the very end.
For you to demean the spectators, and use terms like "practically ejaculating", simply shows me that you are detached emotionally from sporting events, which is a great source of entertainment and pleasure for a very significant number of people.
If you find spectators getting excited over a winner of an event "gross" then I advise you to not attend sporting events or view videos of them, so as to not offend your sensitivities.
One thing that has annoyed me lately is that you now have to be signed in to a Google account to use the PDF preview capability in search results. These aren't "Google Books", but just PDFs on 3rd party sites that Google has retrieved and converted, so the documents are already sitting out there one the web. There's no good reason a person has to be signed in to Google view a preview version of a PDF found in a Google Search.
I can see now, if Google could get away with it, they would require you to be signed in to do just a general web search. Fortunately they would lose too much traffic if they went that far. For now.
You don't have to use the languages the story states for the various platforms. You use C++ or C and OpenGL for the library and use the same code for all 3 platforms. I know because I've done it.
This doesn't exactly fit the topic, but I don't know of a good place to even ask this question. At one time the official advice was to open windows during a tornado, so that pressure inside the building could equalize with the atmosphere, thus reducing destruction. I think that advice has been thrown out, because if a tornado does hit your house it's toast, and at least having your windows closed gives a little protection from flying debris and hail.
However, the opening windows advice does sound good for massive shock waves, like from a meteor. If you'll notice in the videos showing windows in apartment buildings blowing out, it was pretty evenly distributed across the building. It might have affected 1 in 5 windows or so, which to me appears to have been the necessary amount to equalize pressure in the building. My point is if if that number of windows had been opened on purpose, then I bet none would have had to have blown out.
Anyone know anything specific about this kind of thing?
