and are uniformly shot down as a tax on wealth rather than income. And that is correct: it is, after all, an income tax, not a wealth tax. The author of this piece wishes us to ignore his sleight of hand. That is, this is not a bug, but a feature.
We have plenty of taxes on wealth. Vehicle use taxes, property taxes, etc. Also, as people noted, millionaires and billionaires borrow against these stocks to have cash but avoid paying income tax. Perhaps we could do the mark-to-market tax when the value is assessed and used as collateral for borrowing. In otherword... at the point you use it to get cash out to pay things, it's equivalent to buying and selling it at the assessed price and you pay your capital gains then.
The Article says the tablet will be about $265 with Linux but you can buy the same tablet right now for $138.89. Why not just save half the $$$ and install Linux yourself on it?
I am a professional so I am a little biased here....I say get a DSLR. The mirrorless stuff is a neat idea but slow and lacks in quality compared to a traditional DSLR.
The mirrorless cameras actually have the fastest response times out there. The shutter lag on the upcoming NEX 7 is 0.02s.
I wont own a Sony because I have personal issues against the entire brand, but the NEX5 NEX7 cameras are awesome at photos and video.
The NEX 7 will not be available to purchase until April 2012 due to production issues and flooding in Thailand. Certain camera professionals and reviewers were able to get "review" models of the camera earlier in 2011 but no one can yet make claims about the actual shipping NEX 7 camera.
I think your missing the point. They have restricted the only avenue to access the underlying software to make changes. If they did this update while giving all users the ability to alter the software via another approved method, there would be no issue. The fact that they have restricted all access to your own PURCHASED hardware is the issue.
I was under the impression that Kindle Fire did not have an encrypted boot loader and that Amazon has already released the source to the OS.
Few people have any real need to sacrifice stability for a little more speed. Overclocking is pretty pointless for anyone with a modern CPU.
Not true... For example, Intels i7 2700K is an unlocked chip basically intended for overclocking. The stock speed is 3.5 GHz but with a simple Corsair Water Cooler just about anyone can get a stable overclock to 4.7GHz and that makes a huge difference in any CPU limited games and video transcoding. There are people going as high as 5.2GHz and stable on simple all-in-one water coolers like the H100.
Root access was a security risk. I'm glad Amazon fixed that.
If it's Windoze, an unfixed privilege escalation exploit leads to Slashdotters calling Microsoft out as a shoddy company. When Amazon fixes the same type of security issue, they are accused of crushing homebrew development. Let's face it... security bugs should be fixed.
Homebrew is only related in that it's using security flaws to root the device. If Amazon wants to support homebrew, they should do it in a way that doesn't compromise the current OS. Not leaving security bugs where anyone can take over your device is not the same as trying to quash homebrew -- it's a security upgrade that benefits 99.999% of the platform owners and security-exploit-based-homebrew is merely collateral damage.
My 20 year class reunion was ORGANIZED on Facebook. Facebook allowed people to track down and more easily notify classmates. I actually feel that more people attended because of Facebook and the technology it provided to keep in touch.
Why? Because they fill a niche, and do it well. And the thing about social networks is this: whoever is the biggest is probably going to stay the biggest at this point. It's no good joining a social network that none of your friends use. And to some folks, Facebook is the internet.
Probably never???
At one point a lot of people thought AOL was "The Internet". Then MySpace.com was "The Internet". Other sites like Orkut, Buzz, Waves, etc may have tried and failed to replace FB but FB replaced AOL and MySpace. I would hardly consider Facebook to immortal or irreplaceable. It's time for being "The Internet" depends solely upon the whims of fickle users.
So iOS is secure against developers that tell Apple about the malware in their apps. That gives me a really warm, fuzzy feeling...
Yes... however, if Apple finds malware in an App, it is pulled from the App Store and the developer is banned. But anything you install could be potentially malware. Then again, I'd venture to say malicious developers can take advantage of *ANY* current software platform once you've installed their software.
If I can reverse-engineer the uninformative article a little, I would hazard a guess to say that he's found a way of bypassing the NX bit protection using Safari as an attack vector. This means that he would be able to inject arbitrary ARM code that wasn't present on the device at review time, meaning that he could execute code against APIs that the application wasn't originally using (but which are available for applications to use legitimately).
Nope, he wrote a Sleeper App (basically malware with trojan functionality) and put it up on the App-Store. Using the "backdoor" in the App, he could download, install and run unsigned code. Apps in the App Store run binary code. You don't need to inject code anywhere into a browser.
Also, what he did was EXPLICITLY AGAINST the developer agreement he made when he became an Apple Developer. He basically proved that you could write code with trojan functionality that violated developer agreements, lie about the functionality to Apple, and get it published on the App Store. Apple found out and took his App down and then took away his developer license.
On a netbook, tablet or phone, about 70% of the initial home page view is ads -- and not unbotrusive ones (those make up the bottom 50% of the page when you scroll down with web link ads).

Basically any site this cluttered is gonna be dying and starving for cash as the PostPC-browser age comes into full swing.
I have worked on optimizing computer algorithms for over 20 years. I'm going to assume that you are just a troll since you have made extremely obvious novice mistakes in your mathematics in every post so far that even a first or second year computer science student should be able to avoid.
Thanks SnowGirl for showing me there are actually other intelligent people who read Slashdot and who understand Mathematics as they apply to Computer Science. If this guy actually graduated Comp Sci, then sadly his school failed to teach him:-(
Sure, but you're comparing apples and oranges. The O(N^2) refers to the actual flipping time, while NP refers to the algorithm used for determining the minimum number of flips.
Wrong again. Sorry but that's the second basic comp sci "quiz" question you've flunked in a row. Have you actually taken an algorithms class where you determine order of magnitude and how that affects optimization?
It can be TRIVIALLY shown by using a simple "selection sort" of flipping to largest unsorted pancake to the top and then flipping that pancake down to the next sort position that the maximum number of flips required is only 2N. The reason the algorthim is O(N^2) is for the comparison work (non flipping): presumably, you go through all the unsorted pancakes in the stack between each flip O(N) to find the next largest one. So your flip time is actually only O(N) but you need to multiply by the compare time O(N) to get a final magnitude of O(N^2).
And still it doesn't matter if the NP refers to the amount of time to determine the flips. Eventually there is some number of elements (as the element count grows) at which it goes so much slower that it vastly outweighs the flipping time.
In other words, you could take an hour per flip and the computer might take 1 microsecond per comparison but eventually NP grows enough faster than N^2 (for an very large stack of pancakes mind you), that those time constants for single operations don't matter.
Now in the "real world" for hard optimizations vs comp sci, those time constants do matter. And most programmers who are concerned with performance for both small and extremely large sets simply write two versions of the functions and switch between them based on a threshold so you pick the optimal one either way (or at least close to the optimal one).
In fact, you see this in many quicksort implementations when they get down to less than N elements (5-10) they will switch to another method that is higher order but lower linear constant. See this qsort.c source for an example.
Not necessarily. Maybe it could take 1 billion calculations to figure out the optimal algorithm with an NP algorithm. But if a computer can do those calculations in 1 second total, while it takes you 2 seconds per flip, it's still worth it to spend all those CPU cycles.
Ummm... no... You are not only completely wrong here, you would also fail your basic comp sci exam when explaining how order of magnitude matters. In the long run as the number of pancakes in the stack gets greater, no matter how large the linear constant is, eventually NP becomes much greater than N^2.
That's how math works and the reason why Computer Scientists drop the constants when comparing O(N) vs O(N lgN) vs O(N^2) vs O(NP). If the constant for the higher order algorithm is very small compared to the constant for the lower order algorithm, then the higher order algorithm may be faster for some small number of elements, but there is *ALWAYS* some finite tipping point in the count of elements for finite linear constants where the ORDER OF MAGNITUDE of the operation OUTWEIGHS THE LINEAR CONSTANTS and the lower order algorithm will *ALWAYS* win out as the element count approaches infinity.
Oh, I see. The problem is not that pancake flipping itself is hard, that determining the optimal pancake flipping algorithm for a stack is hard. That's believable.
Yeah... well since finding the optimal flipping solution is NP hard, you'll save time with the simple O(N^2) solution.

On the other hand, it would not be cheap to conduct a proper survey.
Apple already has all the data on sales figures in a database (they need to in order to have stats like top selling app). For Apple, it'd be a cheap and simple database query to aggregate the results.
Getting Apple to release any of the sales data though is a whole different ball of wax.
Amazon is selling this device at a very low margin... perhaps even at a loss. They are assuming you will purchase media -- books, movies, music, apps or streaming thru Amazon Prime. It's a media consumption device and they plan on making the bulk of their money each time you purchase media for the device.
Can I root it and put the Android App store on it?
I'm sure that it will be possible to root it someday. However, the OS is a heavily customized and modified earlier version of Android so Android Apps from any Generic Store might not work. In fact, it is my guess that all Android Apps for the device require minor modifications (screen resolution and other calls) although "porting" between Android Flavors should be fairly easy.
Besides it comes with Amazon App Store which is actually an Android App Store and they give away one free paid App a day so you don't even need to Pirate Apps (oops I mean BUY -- silly for assuming Piracy as why you'd want to "root" when you only mention the App Store and not development). Just wait for the App you want to come up on a free day.

Last I heard, Warner Brothers is a pretty big company: Mortal Kombat: Legacy
This isn't about "original" content, it's about professional Hollywood content. In other words: "Television".
Warner Brothers and Netherrealm Studios produced an entire original series called Mortal Kombat: Legacy for YouTube.
The series did quite well and actually had a number of viewing hits that were fairly competitive with the top 5 cable TV shows at the time.
Disclaimer: I work for Netherrealm Studios which is owned by WB but nothing I say is directly representative of either company.
