Size is still going to be an issue. 1 farad gives you 1 volt at 1 amp for 1 second. Consider you need 5 volts to run the SSD reliably, that gives you 200mA for 1 second while dropping steadily (R/C time constant) towards 0 volts. This 1 farad of capacitance will be roughly the size of a stack of 15 - 20 quarters (or nickels if you want to pay 2X) and would take up lots of space in an SSD
I played around with some supercaps on an embedded flash based datalogger I designed, and without lots of CPU cycle consuming software monitoring and trigger circuitry I had much less corruption with a diode isolated normal (tiny) cap powering the flash chip, and nothing besides power conditioning on the CPU. That way if the flash had a buffer write in progress it would complete, but the CPU would go dead nearly instantly during brownout and not continue to try and operate until the power supply got so low (1000 mSec or so) that things started to have problems with logic levels and such. I had enough Capacitance to communicate on the bus, and debug status in the background for nearly 2 seconds after poweroff and under normal conditions I was by far the last device left communicating on the CAN bus I was monitoring, but if I lost power, and the bus continued to operate and I tried to ride it out and still record data to the bitter end hoping I would get my power back before I went dead, I saw failed writes and corrupted data. I had to use hardware triggers on the power supply to get an early signal so the CPU to decide when the power supply was stable enough to continue, or if I needed to issue a write command immediately to flush the buffer and ensure the data was safe and in the meantime buffer in CPU RAM and wait to see if things improved by the time I got confirmation that the page was written so I could decide if I could sneak another 20 mSec sample into flash. It was a lot of additional hardware and software (and highly targeted testing) to get any additional improvement in data reliability over version 1.0 that just died when the power did. I doubt your SSD manufacturer cares that much about such edge cases as we did (I even stored our supply voltage and hardware trigger status with every sample) when validating drive by wire systems.
One thing I thought about while reading this paper was that they should have stopped writing to the SSD when power was cut to it, because it's kind of unfair to cut the power on your storage device that's fed from the same power as the CPU, but to have some magic ability for that CPU to keep writing after it normally would be dead. It's worst case, but might not be real world.
Seems they've gotten to Bit-9, and found ways to get around that too.
OS security needs to have a major makeover, zero days for sale to the highest bidder, state sponsored malware with forged certs, vulnerabilities everywhere.
I guess what strikes me as odd is that you do a good job of providing details about the Emoji, but provide nothing about what Scroll Ninja is even though it is going to consume half of your resources.
Are there goals for Scroll Ninja to go along with the various levels of funding? Can you provide links to the potential investors that give information on it's current status? What platform is it for? Is it going to be completed (enough to play) if you reach level 1 funding with only 250 hours of time to spend on it? How much will another 2000 hours of time add to the game? Will you make more levels, support more platforms, more weapons etc. What's missing is something to tell how additional funding will help the game as well as it is a significant portion of the project cost.
Please bear in mind I in no way was trying to implicate that you were going to scam people out of there money (I copied your where's the money going statement) I was only saying that half of the money raised was going to a different unrelated project that does not have any visibility or stated goals in the main description.
I think actually stating that you have 2 developers working for $10 an hour each will also help your cause, as this is double dirt cheap for anyone talented enough to do these sorts of things!
I would also donate to Scroll Ninja (if I knew what effect my $ was having) as I am of the side scrolling 2D generation, and enjoy those types of games, so increased visibility of the game in your kickstarter description and goals will IMHO will only help your chances of getting more funding!
Including a link to the Github page may also increase your odds of gathering investors, or contributors to the game that you may not have gotten before!
I just think that if half of the money raised is really going to another project that they have a responsibility to the potential investors that the other project should be better defined. What is the game? Any screenshots? A link to a demo, or the current Github page? How is the game going to progress through the different levels of funding? What point is the game at now? At what level of funding is it going to be playable? Can it be completed with 250 hours of work if funded to level one? How will going from $5,000 to $50,000 make the game better? None of this is spelled out, yet it is half the cost of the project. Each level of funding should include clear goals for the game. The current state, and the reasons it should be completed should be included in the introduction along with the other half of the project which includes all of those details.
I've spent 20 years in product development, working with customers, and impressing investors, I know development costs get split, and resources are shared, but when dealing with investors, they typically want to know where the money is going beyond half of it is going to something else we really think didn't get the chance it deserved. The first thing they would ask is tell me more about this other project.
Imagine making a PowerPoint presentation from the Kickstarter page. You'd have 10 slides, and on the bottom of the 9th slide there'd be two sentences that state half of the money raised is going to something else completely unrelated, and the hands would go up.
The cost of developing the next iThingy is nowhere close to 50% of the available financial resources of Apple, it's a drop in the bucket, and hardly the same thing as what's going on here.
When you're standing at the store contemplating a widget, that product is right there in front of you, already done. Even then, if a sign said to purchase this widget, you also agree to purchase our game (or even said the game was included free with purchase) unless you were hell bent on purchasing said widget, you'd likely want to know more about the game because you know that some of your money (and usually not half of it) is going towards the purchase of that game. You would still know that a portion of your overall purchase would be going to the store stocking other items which you have no interest in purchasing, paying employees, keeping the lights on etc. but that (IMHO) is different because it is a part of doing business, not part of the free game offer.
Would you give to a charity that said half of all the money donated is going to my little sister so she can write that book she's been talking about, or would you perhaps look for a charity that was going to spend all their resources on the cause you wish to help.
My comment about Congress was relating to how they put multiple things on the same bill so one gets snuck in with the other that is more popular.
I just think that a kickstarter should be about one project to be able to have the best chance at success for the investors, especially when the projects as unrelated as these two are.
If Apple was going to take half the cost of your itoy (or perhaps double the cost of it so they could make the Apple Lisa the success it should have been, would their investors be all for it?
If the project was desired it should have been able to get funded on it's own. To force it on an unrelated project to me seems dishonest.
I know we don't like it when Congress sneaks things in like that, and I know that if I spent half my work time or budget working on a project that was canceled that I just really wanted to see finished anyways, it wouldn't go over to well either.
The slippery ninja should be able to stand on it's own two feet, not ride on the back of something they feel might have a (better) chance of succeeding after it wasn't successful on it's own.
It could also cost them investors, and ruin their chance to get this project funded. The two are completely unrelated and someone who wants cute smileys might not want a previously failed ninja side scroller.
It also makes me wonder if they are paying them $10 an hour each or $20, and how much the icons really cost.
Is the source code or binary of the game going to be released for free as well, or are they going to sell it and make money off a project for a free product?
We're calculating work time at roughly $20 per work hour for Tohyama, which is lower than what we usually bill him at. Even then half of that rate will go to paying Scroll Ninja lead developer Iwakawa so he can continue working on Scroll Ninja... since we didn't get funded but want to continue anyway
So half of your money won't even go to the project!
My guess is that the electric portion is not so much there to be an electric car, but to increase the efficiency of the gas car by allowing regenerative braking, and helping a smaller more efficient engine to still have respectable acceleration.
You could also use it in a traffic jam to keep from having to run the engine constantly the movie 5 feet every minute or so.
The Prius is a hybrid, not really an electric car.

It seems that the newer smartphone OS's exist to provide your personal life to their creators, and push the limits of the invasion of your privacy, whereas the "last gen" smartphones were trying to provide a pocket-sized computing experience that could be safely used to access sensitive corporate networks, and push the limits of technology.
We lost something along the way...
WinMo was never the best technology, or the best OS, but it was built to be a platform you had full control over and you could conceivably trust accessing and storing your private personal and corporate data.
Look at the incredible amount of work that Google puts into Android only to give it away. It's like downloading cracked software from a warez site that also installs a keylogger. Nothing is free, you're paying with your privacy, and people are waiting in line to trade it for a shiny gadget.
I'm really hoping BB10, Firefox, Ubuntu or someone (miss you WebOS) steps up to provide a secure user focused phone based computing experience again!
That's one thing I really miss about my old WinMo phones. They were not a data harvesting device, just a phone, with computer functionality. Every device I've had since then just seems like it's spying on me and siphoning off my personal life for someone else's gain.
I've run into that issue as well, but so far, this has worked every time.

It's actually much easier to do before the computer dies, or right before you do your clonezilla backup. I have VM images of all of our SCADA PCs so I can test changes before pushing them out onto the line, and I have to do this every time I clone a disk to move it to my VM. After fighting this on the first PC that crashed on us with no backup, I went around and did it to all of our PCs. They now have the additional entries already in the registry so they are ready to go and can be cloned to different computer, and boot so they just have to install the plug-and-pray devices that are different.
For a more complicated switcheroo, you can tell windows to reexamine and repair the install on the next reboot by setting the appropriate registry keys.This article is sometimes helpful:

I really like the way Linux just works, and examines the hardware during boot. It eliminates the BS you have to go through when swapping a HDD from one computer to a different one!
The only problem is the newspapers are probably hoping to get email from China that contains juicy tidbits to splash on their pages. They were probably hacked by China tricking them with emails that were fakes of the same types of emails that China was looking for by hacking them.
Makes it hard to know if you should open some random email from China or not! The rest of us (should) know better, but the news has a certain urge to open them.
I found I had to learn how to use them as I end up fixing lots of laptops that have nothing but a touchpad because the people coming to me for help with their computer are smart enough to get the hang of theirs.
One thing I think helps a lot is spend 5 minutes with the settings window open, and try to make a move that you feel should get a certain response from the touchpad, and adjust it to get a result that is close to what you feel it should do. Start with the small movements and set the sensitivity to make those come out, then use acceleration to get you to menus and icons on various points around the screen.
Once you get the hang of one (which setting it to yourself helps) adapting to someone else's is not too hard.
I'll still take a Thinkpad clit over anything else though!
Agreed. The purpose of these large screens is to provide status updates, and give notice to things requiring special attention. Something that color was born for. It's very difficult to draw attention to something on a monochrome display.
Having the majority of the content grey and saving the black for important items, or trying to make something flash on E-Ink would make an unreadable mess of it all.
It took me less than an hour including moving the furniture (:and splicing the cable:) and I'm sure the next guy would appreciate the free cable (ahemm, i I mean coax and Cat5) only problem is my landlord has an aversion to returning the security deposit, and after he jipped my friend out of $400 to pick up 5 softballs his kids lost in the weeds by the back yard when he moved out, I think I'll take it with me:)
You can easily tuck them under the baseboard, use a flat screwdriver turned sideways to tuck them between the baseboard and the carpet and run them right against the wall. there's room for 2 or 3 cords under there in most houses. If it crosses a doorway and the trim strip is too small, just get a piece of trim that will fit over it, and tack it to the floor over the wires.
I have a coax, and a cat 5 cable running from my bedroom, down the hall, around the living room, and into the kitchen closet, and it's completely invisible. When I move, I just grab one end, and pull it out.
Look we have this poison that will kill any plant it comes near, and leave nothing but a barren wasteland of dead dirt...
Now look, we made this corn that you can douse in the previously mentioned poison, and it will continue to grow despite the fact that everything else that comes near it shrivels up and promptly dies...
Of course it's safe to eat, and causes no long term health problems... It is as good for you as the non-poisoned variety, we designed, and tested it...

I wonder how the write times change when they become over-write times, and sectors have to be erased before they can be written.
